[+] marked option can be specified multiple times
COMMANDS¶
add¶
add the specified files on the next commit:
hg add [OPTION]... [FILE]...
Schedule files to be version controlled and added to the repository.
The files will be added to the repository at the next commit. To undo an add
before that, see
hg forget.
If no names are given, add all files to the repository.
An example showing how new (unknown) files are added automatically by
hg
add:
$ ls
foo.c
$ hg status
? foo.c
$ hg add
adding foo.c
$ hg status
A foo.c
Returns 0 if all files are successfully added.
Options:
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
- -S, --subrepos
- recurse into subrepositories
- -n, --dry-run
- do not perform actions, just print output
[+] marked option can be specified multiple times
addremove¶
add all new files, delete all missing files:
hg addremove [OPTION]... [FILE]...
Add all new files and remove all missing files from the repository.
New files are ignored if they match any of the patterns in
.hgignore. As
with add, these changes take effect at the next commit.
Use the -s/--similarity option to detect renamed files. This option takes a
percentage between 0 (disabled) and 100 (files must be identical) as its
parameter. With a parameter greater than 0, this compares every removed file
with every added file and records those similar enough as renames. Detecting
renamed files this way can be expensive. After using this option,
hg status
-C can be used to check which files were identified as moved or renamed.
If not specified, -s/--similarity defaults to 100 and only renames of
identical files are detected.
Returns 0 if all files are successfully added.
Options:
- -s,--similarity <SIMILARITY>
- guess renamed files by similarity (0<=s<=100)
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
- -n, --dry-run
- do not perform actions, just print output
[+] marked option can be specified multiple times
annotate¶
show changeset information by line for each file:
hg annotate [-r REV] [-f] [-a] [-u] [-d] [-n] [-c] [-l] FILE...
List changes in files, showing the revision id responsible for each line
This command is useful for discovering when a change was made and by whom.
Without the -a/--text option, annotate will avoid processing files it detects as
binary. With -a, annotate will annotate the file anyway, although the results
will probably be neither useful nor desirable.
Returns 0 on success.
Options:
- -r,--rev <REV>
- annotate the specified revision
- --follow
- follow copies/renames and list the filename
(DEPRECATED)
- --no-follow
- don't follow copies and renames
- -a, --text
- treat all files as text
- -u, --user
- list the author (long with -v)
- -f, --file
- list the filename
- -d, --date
- list the date (short with -q)
- -n, --number
- list the revision number (default)
- -c, --changeset
- list the changeset
- -l, --line-number
- show line number at the first appearance
- -w, --ignore-all-space
- ignore white space when comparing lines
- -b, --ignore-space-change
- ignore changes in the amount of white space
- -B, --ignore-blank-lines
- ignore changes whose lines are all blank
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
archive¶
create an unversioned archive of a repository revision:
hg archive [OPTION]... DEST
By default, the revision used is the parent of the working directory; use
-r/--rev to specify a different revision.
The archive type is automatically detected based on file extension (or override
using -t/--type).
Examples:
- •
- create a zip file containing the 1.0 release:
hg archive -r 1.0 project-1.0.zip
- •
- create a tarball excluding .hg files:
hg archive project.tar.gz -X ".hg*"
Valid types are:
- files
-
a directory full of files (default)
- tar
-
tar archive, uncompressed
- tbz2
-
tar archive, compressed using bzip2
- tgz
-
tar archive, compressed using gzip
- uzip
-
zip archive, uncompressed
- zip
-
zip archive, compressed using deflate
The exact name of the destination archive or directory is given using a format
string; see
hg help export for details.
Each member added to an archive file has a directory prefix prepended. Use
-p/--prefix to specify a format string for the prefix. The default is the
basename of the archive, with suffixes removed.
Returns 0 on success.
Options:
- --no-decode
- do not pass files through decoders
- -p,--prefix <PREFIX>
- directory prefix for files in archive
- -r,--rev <REV>
- revision to distribute
- -t,--type <TYPE>
- type of distribution to create
- -S, --subrepos
- recurse into subrepositories
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
backout¶
reverse effect of earlier changeset:
hg backout [OPTION]... [-r] REV
Prepare a new changeset with the effect of REV undone in the current working
directory.
If REV is the parent of the working directory, then this new changeset is
committed automatically. Otherwise, hg needs to merge the changes and the
merged result is left uncommitted.
- Note
- backout cannot be used to fix either an unwanted or
incorrect merge.
By default, the pending changeset will have one parent, maintaining a linear
history. With --merge, the pending changeset will instead have two parents:
the old parent of the working directory and a new child of REV that simply
undoes REV.
Before version 1.7, the behavior without --merge was equivalent to specifying
--merge followed by
hg update --clean . to cancel the merge and leave
the child of REV as a head to be merged separately.
See
hg help dates for a list of formats valid for -d/--date.
Returns 0 on success, 1 if nothing to backout or there are unresolved files.
Options:
- --merge
- merge with old dirstate parent after backout
- --parent <REV>
- parent to choose when backing out merge (DEPRECATED)
- -r,--rev <REV>
- revision to backout
- -e, --edit
- invoke editor on commit messages
- -t,--tool <VALUE>
- specify merge tool
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
- -m,--message <TEXT>
- use text as commit message
- -l,--logfile <FILE>
- read commit message from file
- -d,--date <DATE>
- record the specified date as commit date
- -u,--user <USER>
- record the specified user as committer
[+] marked option can be specified multiple times
bisect¶
subdivision search of changesets:
hg bisect [-gbsr] [-U] [-c CMD] [REV]
This command helps to find changesets which introduce problems. To use, mark the
earliest changeset you know exhibits the problem as bad, then mark the latest
changeset which is free from the problem as good. Bisect will update your
working directory to a revision for testing (unless the -U/--noupdate option
is specified). Once you have performed tests, mark the working directory as
good or bad, and bisect will either update to another candidate changeset or
announce that it has found the bad revision.
As a shortcut, you can also use the revision argument to mark a revision as good
or bad without checking it out first.
If you supply a command, it will be used for automatic bisection. The
environment variable HG_NODE will contain the ID of the changeset being
tested. The exit status of the command will be used to mark revisions as good
or bad: status 0 means good, 125 means to skip the revision, 127 (command not
found) will abort the bisection, and any other non-zero exit status means the
revision is bad.
Some examples:
- •
- start a bisection with known bad revision 34, and good
revision 12:
hg bisect --bad 34
hg bisect --good 12
- •
- advance the current bisection by marking current revision
as good or bad:
hg bisect --good
hg bisect --bad
- •
- mark the current revision, or a known revision, to be
skipped (e.g. if that revision is not usable because of another issue):
hg bisect --skip
hg bisect --skip 23
- •
- skip all revisions that do not touch directories foo
or bar:
hg bisect --skip "!( file('path:foo') & file('path:bar') )"
- •
- forget the current bisection:
hg bisect --reset
- •
- use 'make && make tests' to automatically find the
first broken revision:
hg bisect --reset
hg bisect --bad 34
hg bisect --good 12
hg bisect --command "make && make tests"
- •
- see all changesets whose states are already known in the
current bisection:
hg log -r "bisect(pruned)"
- •
- see the changeset currently being bisected (especially
useful if running with -U/--noupdate):
hg log -r "bisect(current)"
- •
- see all changesets that took part in the current bisection:
hg log -r "bisect(range)"
- •
- you can even get a nice graph:
hg log --graph -r "bisect(range)"
See
hg help revsets for more about the
bisect() keyword.
Returns 0 on success.
Options:
- -r, --reset
- reset bisect state
- -g, --good
- mark changeset good
- -b, --bad
- mark changeset bad
- -s, --skip
- skip testing changeset
- -e, --extend
- extend the bisect range
- -c,--command <CMD>
- use command to check changeset state
- -U, --noupdate
- do not update to target
bookmarks¶
create a new bookmark or list existing bookmarks:
hg bookmarks [OPTIONS]... [NAME]...
Bookmarks are labels on changesets to help track lines of development. Bookmarks
are unversioned and can be moved, renamed and deleted. Deleting or moving a
bookmark has no effect on the associated changesets.
Creating or updating to a bookmark causes it to be marked as 'active'. The
active bookmark is indicated with a '*'. When a commit is made, the active
bookmark will advance to the new commit. A plain
hg update will also
advance an active bookmark, if possible. Updating away from a bookmark will
cause it to be deactivated.
Bookmarks can be pushed and pulled between repositories (see
hg help push
and
hg help pull). If a shared bookmark has diverged, a new 'divergent
bookmark' of the form 'name@path' will be created. Using :hg:'merge' will
resolve the divergence.
A bookmark named '@' has the special property that
hg clone will check it
out by default if it exists.
Examples:
- •
- create an active bookmark for a new line of development:
hg book new-feature
- •
- create an inactive bookmark as a place marker:
hg book -i reviewed
- •
- create an inactive bookmark on another changeset:
hg book -r .^ tested
- •
- move the '@' bookmark from another branch:
hg book -f @
Options:
- -f, --force
- force
- -r,--rev <REV>
- revision
- -d, --delete
- delete a given bookmark
- -m,--rename <NAME>
- rename a given bookmark
- -i, --inactive
- mark a bookmark inactive
aliases: bookmark
branch¶
set or show the current branch name:
hg branch [-fC] [NAME]
- Note
- Branch names are permanent and global. Use hg
bookmark to create a light-weight bookmark instead. See hg help
glossary for more information about named branches and bookmarks.
With no argument, show the current branch name. With one argument, set the
working directory branch name (the branch will not exist in the repository
until the next commit). Standard practice recommends that primary development
take place on the 'default' branch.
Unless -f/--force is specified, branch will not let you set a branch name that
already exists, even if it's inactive.
Use -C/--clean to reset the working directory branch to that of the parent of
the working directory, negating a previous branch change.
Use the command
hg update to switch to an existing branch. Use
hg
commit --close-branch to mark this branch as closed.
Returns 0 on success.
Options:
- -f, --force
- set branch name even if it shadows an existing branch
- -C, --clean
- reset branch name to parent branch name
branches¶
list repository named branches:
hg branches [-ac]
List the repository's named branches, indicating which ones are inactive. If
-c/--closed is specified, also list branches which have been marked closed
(see
hg commit --close-branch).
If -a/--active is specified, only show active branches. A branch is considered
active if it contains repository heads.
Use the command
hg update to switch to an existing branch.
Returns 0.
Options:
- -a, --active
- show only branches that have unmerged heads
- -c, --closed
- show normal and closed branches
bundle¶
create a changegroup file:
hg bundle [-f] [-t TYPE] [-a] [-r REV]... [--base REV]... FILE [DEST]
Generate a compressed changegroup file collecting changesets not known to be in
another repository.
If you omit the destination repository, then hg assumes the destination will
have all the nodes you specify with --base parameters. To create a bundle
containing all changesets, use -a/--all (or --base null).
You can change compression method with the -t/--type option. The available
compression methods are: none, bzip2, and gzip (by default, bundles are
compressed using bzip2).
The bundle file can then be transferred using conventional means and applied to
another repository with the unbundle or pull command. This is useful when
direct push and pull are not available or when exporting an entire repository
is undesirable.
Applying bundles preserves all changeset contents including permissions,
copy/rename information, and revision history.
Returns 0 on success, 1 if no changes found.
Options:
- -f, --force
- run even when the destination is unrelated
- -r,--rev <REV[+]>
- a changeset intended to be added to the destination
- -b,--branch <BRANCH[+]>
- a specific branch you would like to bundle
- --base <REV[+]>
- a base changeset assumed to be available at the
destination
- -a, --all
- bundle all changesets in the repository
- -t,--type <TYPE>
- bundle compression type to use (default: bzip2)
- -e,--ssh <CMD>
- specify ssh command to use
- --remotecmd <CMD>
- specify hg command to run on the remote side
- --insecure
- do not verify server certificate (ignoring web.cacerts
config)
[+] marked option can be specified multiple times
cat¶
output the current or given revision of files:
hg cat [OPTION]... FILE...
Print the specified files as they were at the given revision. If no revision is
given, the parent of the working directory is used.
Output may be to a file, in which case the name of the file is given using a
format string. The formatting rules as follows:
- %%
-
literal "%" character
- %s
-
basename of file being printed
- %d
-
dirname of file being printed, or '.' if in repository root
- %p
-
root-relative path name of file being printed
- %H
-
changeset hash (40 hexadecimal digits)
- %R
-
changeset revision number
- %h
-
short-form changeset hash (12 hexadecimal digits)
- %r
-
zero-padded changeset revision number
- %b
-
basename of the exporting repository
Returns 0 on success.
Options:
- -o,--output <FORMAT>
- print output to file with formatted name
- -r,--rev <REV>
- print the given revision
- --decode
- apply any matching decode filter
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
clone¶
make a copy of an existing repository:
hg clone [OPTION]... SOURCE [DEST]
Create a copy of an existing repository in a new directory.
If no destination directory name is specified, it defaults to the basename of
the source.
The location of the source is added to the new repository's
.hg/hgrc
file, as the default to be used for future pulls.
Only local paths and
ssh:// URLs are supported as destinations. For
ssh:// destinations, no working directory or
.hg/hgrc will be
created on the remote side.
To pull only a subset of changesets, specify one or more revisions identifiers
with -r/--rev or branches with -b/--branch. The resulting clone will contain
only the specified changesets and their ancestors. These options (or 'clone
src#rev dest') imply --pull, even for local source repositories. Note that
specifying a tag will include the tagged changeset but not the changeset
containing the tag.
If the source repository has a bookmark called '@' set, that revision will be
checked out in the new repository by default.
To check out a particular version, use -u/--update, or -U/--noupdate to create a
clone with no working directory.
For efficiency, hardlinks are used for cloning whenever the source and
destination are on the same filesystem (note this applies only to the
repository data, not to the working directory). Some filesystems, such as AFS,
implement hardlinking incorrectly, but do not report errors. In these cases,
use the --pull option to avoid hardlinking.
In some cases, you can clone repositories and the working directory using full
hardlinks with
$ cp -al REPO REPOCLONE
This is the fastest way to clone, but it is not always safe. The operation is
not atomic (making sure REPO is not modified during the operation is up to
you) and you have to make sure your editor breaks hardlinks (Emacs and most
Linux Kernel tools do so). Also, this is not compatible with certain
extensions that place their metadata under the .hg directory, such as mq.
Mercurial will update the working directory to the first applicable revision
from this list:
- a.
- null if -U or the source repository has no changesets
- b.
- if -u . and the source repository is local, the first
parent of the source repository's working directory
- c.
- the changeset specified with -u (if a branch name, this
means the latest head of that branch)
- d.
- the changeset specified with -r
- e.
- the tipmost head specified with -b
- f.
- the tipmost head specified with the url#branch source
syntax
- g.
- the revision marked with the '@' bookmark, if present
- h.
- the tipmost head of the default branch
- i.
- tip
Examples:
- •
- clone a remote repository to a new directory named hg/:
hg clone http://selenic.com/hg
- •
- create a lightweight local clone:
hg clone project/ project-feature/
- •
- clone from an absolute path on an ssh server (note
double-slash):
hg clone ssh://user@server//home/projects/alpha/
- •
- do a high-speed clone over a LAN while checking out a
specified version:
hg clone --uncompressed http://server/repo -u 1.5
- •
- create a repository without changesets after a particular
revision:
hg clone -r 04e544 experimental/ good/
- •
- clone (and track) a particular named branch:
hg clone http://selenic.com/hg#stable
See
hg help urls for details on specifying URLs.
Returns 0 on success.
Options:
- -U, --noupdate
- the clone will include an empty working copy (only a
repository)
- -u,--updaterev <REV>
- revision, tag or branch to check out
- -r,--rev <REV[+]>
- include the specified changeset
- -b,--branch <BRANCH[+]>
- clone only the specified branch
- --pull
- use pull protocol to copy metadata
- --uncompressed
- use uncompressed transfer (fast over LAN)
- -e,--ssh <CMD>
- specify ssh command to use
- --remotecmd <CMD>
- specify hg command to run on the remote side
- --insecure
- do not verify server certificate (ignoring web.cacerts
config)
[+] marked option can be specified multiple times
commit¶
commit the specified files or all outstanding changes:
hg commit [OPTION]... [FILE]...
Commit changes to the given files into the repository. Unlike a centralized SCM,
this operation is a local operation. See
hg push for a way to actively
distribute your changes.
If a list of files is omitted, all changes reported by
hg status will be
committed.
If you are committing the result of a merge, do not provide any filenames or
-I/-X filters.
If no commit message is specified, Mercurial starts your configured editor where
you can enter a message. In case your commit fails, you will find a backup of
your message in
.hg/last-message.txt.
The --amend flag can be used to amend the parent of the working directory with a
new commit that contains the changes in the parent in addition to those
currently reported by
hg status, if there are any. The old commit is
stored in a backup bundle in
.hg/strip-backup (see
hg help
bundle and
hg help unbundle on how to restore it).
Message, user and date are taken from the amended commit unless specified. When
a message isn't specified on the command line, the editor will open with the
message of the amended commit.
It is not possible to amend public changesets (see
hg help phases) or
changesets that have children.
See
hg help dates for a list of formats valid for -d/--date.
Returns 0 on success, 1 if nothing changed.
Options:
- -A, --addremove
- mark new/missing files as added/removed before
committing
- --close-branch
- mark a branch as closed, hiding it from the branch
list
- --amend
- amend the parent of the working dir
- -s, --secret
- use the secret phase for committing
- -e, --edit
- invoke editor on commit messages
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
- -m,--message <TEXT>
- use text as commit message
- -l,--logfile <FILE>
- read commit message from file
- -d,--date <DATE>
- record the specified date as commit date
- -u,--user <USER>
- record the specified user as committer
- -S, --subrepos
- recurse into subrepositories
[+] marked option can be specified multiple times
config¶
show combined config settings from all hgrc files:
hg config [-u] [NAME]...
With no arguments, print names and values of all config items.
With one argument of the form section.name, print just the value of that config
item.
With multiple arguments, print names and values of all config items with
matching section names.
With --edit, start an editor on the user-level config file. With --global, edit
the system-wide config file. With --local, edit the repository-level config
file.
With --debug, the source (filename and line number) is printed for each config
item.
See
hg help config for more information about config files.
Returns 0 on success, 1 if NAME does not exist.
Options:
- -u, --untrusted
- show untrusted configuration options
- -e, --edit
- edit user config
- -l, --local
- edit repository config
- -g, --global
- edit global config
aliases: showconfig debugconfig
copy¶
mark files as copied for the next commit:
hg copy [OPTION]... [SOURCE]... DEST
Mark dest as having copies of source files. If dest is a directory, copies are
put in that directory. If dest is a file, the source must be a single file.
By default, this command copies the contents of files as they exist in the
working directory. If invoked with -A/--after, the operation is recorded, but
no copying is performed.
This command takes effect with the next commit. To undo a copy before that, see
hg revert.
Returns 0 on success, 1 if errors are encountered.
Options:
- -A, --after
- record a copy that has already occurred
- -f, --force
- forcibly copy over an existing managed file
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
- -n, --dry-run
- do not perform actions, just print output
[+] marked option can be specified multiple times
diff¶
diff repository (or selected files):
hg diff [OPTION]... ([-c REV] | [-r REV1 [-r REV2]]) [FILE]...
Show differences between revisions for the specified files.
Differences between files are shown using the unified diff format.
- Note
- diff may generate unexpected results for merges, as it will
default to comparing against the working directory's first parent
changeset if no revisions are specified.
When two revision arguments are given, then changes are shown between those
revisions. If only one revision is specified then that revision is compared to
the working directory, and, when no revisions are specified, the working
directory files are compared to its parent.
Alternatively you can specify -c/--change with a revision to see the changes in
that changeset relative to its first parent.
Without the -a/--text option, diff will avoid generating diffs of files it
detects as binary. With -a, diff will generate a diff anyway, probably with
undesirable results.
Use the -g/--git option to generate diffs in the git extended diff format. For
more information, read
hg help diffs.
Examples:
- •
- compare a file in the current working directory to its
parent:
hg diff foo.c
- •
- compare two historical versions of a directory, with rename
info:
hg diff --git -r 1.0:1.2 lib/
- •
- get change stats relative to the last change on some date:
hg diff --stat -r "date('may 2')"
- •
- diff all newly-added files that contain a keyword:
hg diff "set:added() and grep(GNU)"
- •
- compare a revision and its parents:
hg diff -c 9353 # compare against first parent
hg diff -r 9353^:9353 # same using revset syntax
hg diff -r 9353^2:9353 # compare against the second parent
Returns 0 on success.
Options:
- -r,--rev <REV[+]>
- revision
- -c,--change <REV>
- change made by revision
- -a, --text
- treat all files as text
- -g, --git
- use git extended diff format
- --nodates
- omit dates from diff headers
- -p, --show-function
- show which function each change is in
- --reverse
- produce a diff that undoes the changes
- -w, --ignore-all-space
- ignore white space when comparing lines
- -b, --ignore-space-change
- ignore changes in the amount of white space
- -B, --ignore-blank-lines
- ignore changes whose lines are all blank
- -U,--unified <NUM>
- number of lines of context to show
- --stat
- output diffstat-style summary of changes
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
- -S, --subrepos
- recurse into subrepositories
[+] marked option can be specified multiple times
export¶
dump the header and diffs for one or more changesets:
hg export [OPTION]... [-o OUTFILESPEC] [-r] [REV]...
Print the changeset header and diffs for one or more revisions. If no revision
is given, the parent of the working directory is used.
The information shown in the changeset header is: author, date, branch name (if
non-default), changeset hash, parent(s) and commit comment.
- Note
- export may generate unexpected diff output for merge
changesets, as it will compare the merge changeset against its first
parent only.
Output may be to a file, in which case the name of the file is given using a
format string. The formatting rules are as follows:
- %%
-
literal "%" character
- %H
-
changeset hash (40 hexadecimal digits)
- %N
-
number of patches being generated
- %R
-
changeset revision number
- %b
-
basename of the exporting repository
- %h
-
short-form changeset hash (12 hexadecimal digits)
- %m
-
first line of the commit message (only alphanumeric characters)
- %n
-
zero-padded sequence number, starting at 1
- %r
-
zero-padded changeset revision number
Without the -a/--text option, export will avoid generating diffs of files it
detects as binary. With -a, export will generate a diff anyway, probably with
undesirable results.
Use the -g/--git option to generate diffs in the git extended diff format. See
hg help diffs for more information.
With the --switch-parent option, the diff will be against the second parent. It
can be useful to review a merge.
Examples:
- •
- use export and import to transplant a bugfix to the current
branch:
hg export -r 9353 | hg import -
- •
- export all the changesets between two revisions to a file
with rename information:
hg export --git -r 123:150 > changes.txt
- •
- split outgoing changes into a series of patches with
descriptive names:
hg export -r "outgoing()" -o "%n-%m.patch"
Returns 0 on success.
Options:
- -o,--output <FORMAT>
- print output to file with formatted name
- --switch-parent
- diff against the second parent
- -r,--rev <REV[+]>
- revisions to export
- -a, --text
- treat all files as text
- -g, --git
- use git extended diff format
- --nodates
- omit dates from diff headers
[+] marked option can be specified multiple times
forget¶
forget the specified files on the next commit:
hg forget [OPTION]... FILE...
Mark the specified files so they will no longer be tracked after the next
commit.
This only removes files from the current branch, not from the entire project
history, and it does not delete them from the working directory.
To undo a forget before the next commit, see
hg add.
Examples:
- •
- forget newly-added binary files:
hg forget "set:added() and binary()"
- •
- forget files that would be excluded by .hgignore:
hg forget "set:hgignore()"
Returns 0 on success.
Options:
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
graft¶
copy changes from other branches onto the current branch:
hg graft [OPTION]... [-r] REV...
This command uses Mercurial's merge logic to copy individual changes from other
branches without merging branches in the history graph. This is sometimes
known as 'backporting' or 'cherry-picking'. By default, graft will copy user,
date, and description from the source changesets.
Changesets that are ancestors of the current revision, that have already been
grafted, or that are merges will be skipped.
If --log is specified, log messages will have a comment appended of the form:
(grafted from CHANGESETHASH)
If a graft merge results in conflicts, the graft process is interrupted so that
the current merge can be manually resolved. Once all conflicts are addressed,
the graft process can be continued with the -c/--continue option.
- Note
- The -c/--continue option does not reapply earlier
options.
Examples:
- •
- copy a single change to the stable branch and edit its
description:
hg update stable
hg graft --edit 9393
- •
- graft a range of changesets with one exception, updating
dates:
hg graft -D "2085::2093 and not 2091"
- •
- continue a graft after resolving conflicts:
hg graft -c
- •
- show the source of a grafted changeset:
hg log --debug -r .
See
hg help revisions and
hg help revsets for more about
specifying revisions.
Returns 0 on successful completion.
Options:
- -r,--rev <REV[+]>
- revisions to graft
- -c, --continue
- resume interrupted graft
- -e, --edit
- invoke editor on commit messages
- --log
- append graft info to log message
- -D, --currentdate
- record the current date as commit date
- -U, --currentuser
- record the current user as committer
- -d,--date <DATE>
- record the specified date as commit date
- -u,--user <USER>
- record the specified user as committer
- -t,--tool <VALUE>
- specify merge tool
- -n, --dry-run
- do not perform actions, just print output
[+] marked option can be specified multiple times
grep¶
search for a pattern in specified files and revisions:
hg grep [OPTION]... PATTERN [FILE]...
Search revisions of files for a regular expression.
This command behaves differently than Unix grep. It only accepts Python/Perl
regexps. It searches repository history, not the working directory. It always
prints the revision number in which a match appears.
By default, grep only prints output for the first revision of a file in which it
finds a match. To get it to print every revision that contains a change in
match status ("-" for a match that becomes a non-match, or
"+" for a non-match that becomes a match), use the --all flag.
Returns 0 if a match is found, 1 otherwise.
Options:
- -0, --print0
- end fields with NUL
- --all
- print all revisions that match
- -a, --text
- treat all files as text
- -f, --follow
- follow changeset history, or file history across copies and
renames
- -i, --ignore-case
- ignore case when matching
- -l, --files-with-matches
- print only filenames and revisions that match
- -n, --line-number
- print matching line numbers
- -r,--rev <REV[+]>
- only search files changed within revision range
- -u, --user
- list the author (long with -v)
- -d, --date
- list the date (short with -q)
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
heads¶
show branch heads:
hg heads [-ct] [-r STARTREV] [REV]...
With no arguments, show all open branch heads in the repository. Branch heads
are changesets that have no descendants on the same branch. They are where
development generally takes place and are the usual targets for update and
merge operations.
If one or more REVs are given, only open branch heads on the branches associated
with the specified changesets are shown. This means that you can use
hg
heads . to see the heads on the currently checked-out branch.
If -c/--closed is specified, also show branch heads marked closed (see
hg
commit --close-branch).
If STARTREV is specified, only those heads that are descendants of STARTREV will
be displayed.
If -t/--topo is specified, named branch mechanics will be ignored and only
topological heads (changesets with no children) will be shown.
Returns 0 if matching heads are found, 1 if not.
Options:
- -r,--rev <STARTREV>
- show only heads which are descendants of STARTREV
- -t, --topo
- show topological heads only
- -a, --active
- show active branchheads only (DEPRECATED)
- -c, --closed
- show normal and closed branch heads
- --style <STYLE>
- display using template map file (DEPRECATED)
- -T,--template <TEMPLATE>
- display with template
help¶
show help for a given topic or a help overview:
hg help [-ec] [TOPIC]
With no arguments, print a list of commands with short help messages.
Given a topic, extension, or command name, print help for that topic.
Returns 0 if successful.
Options:
- -e, --extension
- show only help for extensions
- -c, --command
- show only help for commands
- -k,--keyword <VALUE>
- show topics matching keyword
identify¶
identify the working copy or specified revision:
hg identify [-nibtB] [-r REV] [SOURCE]
Print a summary identifying the repository state at REV using one or two parent
hash identifiers, followed by a "+" if the working directory has
uncommitted changes, the branch name (if not default), a list of tags, and a
list of bookmarks.
When REV is not given, print a summary of the current state of the repository.
Specifying a path to a repository root or Mercurial bundle will cause lookup to
operate on that repository/bundle.
Examples:
- •
- generate a build identifier for the working directory:
hg id --id > build-id.dat
- •
- find the revision corresponding to a tag:
hg id -n -r 1.3
- •
- check the most recent revision of a remote repository:
hg id -r tip http://selenic.com/hg/
Returns 0 if successful.
Options:
- -r,--rev <REV>
- identify the specified revision
- -n, --num
- show local revision number
- -i, --id
- show global revision id
- -b, --branch
- show branch
- -t, --tags
- show tags
- -B, --bookmarks
- show bookmarks
- -e,--ssh <CMD>
- specify ssh command to use
- --remotecmd <CMD>
- specify hg command to run on the remote side
- --insecure
- do not verify server certificate (ignoring web.cacerts
config)
aliases: id
import¶
import an ordered set of patches:
hg import [OPTION]... PATCH...
Import a list of patches and commit them individually (unless --no-commit is
specified).
Because import first applies changes to the working directory, import will abort
if there are outstanding changes.
You can import a patch straight from a mail message. Even patches as attachments
work (to use the body part, it must have type text/plain or text/x-patch).
From and Subject headers of email message are used as default committer and
commit message. All text/plain body parts before first diff are added to
commit message.
If the imported patch was generated by
hg export, user and description
from patch override values from message headers and body. Values given on
command line with -m/--message and -u/--user override these.
If --exact is specified, import will set the working directory to the parent of
each patch before applying it, and will abort if the resulting changeset has a
different ID than the one recorded in the patch. This may happen due to
character set problems or other deficiencies in the text patch format.
Use --bypass to apply and commit patches directly to the repository, not
touching the working directory. Without --exact, patches will be applied on
top of the working directory parent revision.
With -s/--similarity, hg will attempt to discover renames and copies in the
patch in the same way as
hg addremove.
Use --partial to ensure a changeset will be created from the patch even if some
hunks fail to apply. Hunks that fail to apply will be written to a
<target-file>.rej file. Conflicts can then be resolved by hand before
hg commit --amend is run to update the created changeset. This flag
exists to let people import patches that partially apply without losing the
associated metadata (author, date, description, ...). Note that when none of
the hunk applies cleanly,
hg import --partial will create an empty
changeset, importing only the patch metadata.
To read a patch from standard input, use "-" as the patch name. If a
URL is specified, the patch will be downloaded from it. See
hg help
dates for a list of formats valid for -d/--date.
Examples:
- •
- import a traditional patch from a website and detect
renames:
hg import -s 80 http://example.com/bugfix.patch
- •
- import a changeset from an hgweb server:
hg import http://www.selenic.com/hg/rev/5ca8c111e9aa
- •
- import all the patches in an Unix-style mbox:
hg import incoming-patches.mbox
- •
- attempt to exactly restore an exported changeset (not
always possible):
hg import --exact proposed-fix.patch
Returns 0 on success, 1 on partial success (see --partial).
Options:
- -p,--strip <NUM>
- directory strip option for patch. This has the same meaning
as the corresponding patch option (default: 1)
- -b,--base <PATH>
- base path (DEPRECATED)
- -e, --edit
- invoke editor on commit messages
- -f, --force
- skip check for outstanding uncommitted changes
(DEPRECATED)
- --no-commit
- don't commit, just update the working directory
- --bypass
- apply patch without touching the working directory
- --partial
- commit even if some hunks fail
- --exact
- apply patch to the nodes from which it was generated
- --import-branch
- use any branch information in patch (implied by
--exact)
- -m,--message <TEXT>
- use text as commit message
- -l,--logfile <FILE>
- read commit message from file
- -d,--date <DATE>
- record the specified date as commit date
- -u,--user <USER>
- record the specified user as committer
- -s,--similarity <SIMILARITY>
- guess renamed files by similarity (0<=s<=100)
aliases: patch
incoming¶
show new changesets found in source:
hg incoming [-p] [-n] [-M] [-f] [-r REV]... [--bundle FILENAME] [SOURCE]
Show new changesets found in the specified path/URL or the default pull
location. These are the changesets that would have been pulled if a pull at
the time you issued this command.
For remote repository, using --bundle avoids downloading the changesets twice if
the incoming is followed by a pull.
See pull for valid source format details.
Examples:
- •
- show incoming changes with patches and full description:
hg incoming -vp
- •
- show incoming changes excluding merges, store a bundle:
hg in -vpM --bundle incoming.hg
hg pull incoming.hg
- •
- briefly list changes inside a bundle:
hg in changes.hg -T "{desc|firstline}\n"
Returns 0 if there are incoming changes, 1 otherwise.
Options:
- -f, --force
- run even if remote repository is unrelated
- -n, --newest-first
- show newest record first
- --bundle <FILE>
- file to store the bundles into
- -r,--rev <REV[+]>
- a remote changeset intended to be added
- -B, --bookmarks
- compare bookmarks
- -b,--branch <BRANCH[+]>
- a specific branch you would like to pull
- -p, --patch
- show patch
- -g, --git
- use git extended diff format
- -l,--limit <NUM>
- limit number of changes displayed
- -M, --no-merges
- do not show merges
- --stat
- output diffstat-style summary of changes
- -G, --graph
- show the revision DAG
- --style <STYLE>
- display using template map file (DEPRECATED)
- -T,--template <TEMPLATE>
- display with template
- -e,--ssh <CMD>
- specify ssh command to use
- --remotecmd <CMD>
- specify hg command to run on the remote side
- --insecure
- do not verify server certificate (ignoring web.cacerts
config)
- -S, --subrepos
- recurse into subrepositories
[+] marked option can be specified multiple times
init¶
create a new repository in the given directory:
hg init [-e CMD] [--remotecmd CMD] [DEST]
Initialize a new repository in the given directory. If the given directory does
not exist, it will be created.
If no directory is given, the current directory is used.
It is possible to specify an
ssh:// URL as the destination. See
hg
help urls for more information.
Returns 0 on success.
Options:
- -e,--ssh <CMD>
- specify ssh command to use
- --remotecmd <CMD>
- specify hg command to run on the remote side
- --insecure
- do not verify server certificate (ignoring web.cacerts
config)
locate¶
locate files matching specific patterns:
hg locate [OPTION]... [PATTERN]...
Print files under Mercurial control in the working directory whose names match
the given patterns.
By default, this command searches all directories in the working directory. To
search just the current directory and its subdirectories, use "--include
.".
If no patterns are given to match, this command prints the names of all files
under Mercurial control in the working directory.
If you want to feed the output of this command into the "xargs"
command, use the -0 option to both this command and "xargs". This
will avoid the problem of "xargs" treating single filenames that
contain whitespace as multiple filenames.
Returns 0 if a match is found, 1 otherwise.
Options:
- -r,--rev <REV>
- search the repository as it is in REV
- -0, --print0
- end filenames with NUL, for use with xargs
- -f, --fullpath
- print complete paths from the filesystem root
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
log¶
show revision history of entire repository or files:
hg log [OPTION]... [FILE]
Print the revision history of the specified files or the entire project.
If no revision range is specified, the default is
tip:0 unless --follow
is set, in which case the working directory parent is used as the starting
revision.
File history is shown without following rename or copy history of files. Use
-f/--follow with a filename to follow history across renames and copies.
--follow without a filename will only show ancestors or descendants of the
starting revision.
By default this command prints revision number and changeset id, tags,
non-trivial parents, user, date and time, and a summary for each commit. When
the -v/--verbose switch is used, the list of changed files and full commit
message are shown.
With --graph the revisions are shown as an ASCII art DAG with the most recent
changeset at the top. 'o' is a changeset, '@' is a working directory parent,
'x' is obsolete, and '+' represents a fork where the changeset from the lines
below is a parent of the 'o' merge on the same line.
- Note
- log -p/--patch may generate unexpected diff output for
merge changesets, as it will only compare the merge changeset against its
first parent. Also, only files different from BOTH parents will appear in
files:.
- Note
- for performance reasons, log FILE may omit duplicate
changes made on branches and will not show removals or mode changes. To
see all such changes, use the --removed switch.
Some examples:
- •
- changesets with full descriptions and file lists:
hg log -v
- •
- changesets ancestral to the working directory:
hg log -f
- •
- last 10 commits on the current branch:
hg log -l 10 -b .
- •
- changesets showing all modifications of a file, including
removals:
hg log --removed file.c
- •
- all changesets that touch a directory, with diffs,
excluding merges:
hg log -Mp lib/
- •
- all revision numbers that match a keyword:
hg log -k bug --template "{rev}\n"
- •
- list available log templates:
hg log -T list
- •
- check if a given changeset is included in a tagged release:
hg log -r "a21ccf and ancestor(1.9)"
- •
- find all changesets by some user in a date range:
hg log -k alice -d "may 2008 to jul 2008"
- •
- summary of all changesets after the last tag:
hg log -r "last(tagged())::" --template "{desc|firstline}\n"

[+] marked option can be specified multiple times
manifest¶
output the current or given revision of the project manifest:
hg manifest [-r REV]
Print a list of version controlled files for the given revision. If no revision
is given, the first parent of the working directory is used, or the null
revision if no revision is checked out.
With -v, print file permissions, symlink and executable bits. With --debug,
print file revision hashes.
If option --all is specified, the list of all files from all revisions is
printed. This includes deleted and renamed files.
Returns 0 on success.
Options:
- -r,--rev <REV>
- revision to display
- --all
- list files from all revisions
merge¶
merge working directory with another revision:
hg merge [-P] [-f] [[-r] REV]
The current working directory is updated with all changes made in the requested
revision since the last common predecessor revision.
Files that changed between either parent are marked as changed for the next
commit and a commit must be performed before any further updates to the
repository are allowed. The next commit will have two parents.
--tool can be used to specify the merge tool used for file merges. It
overrides the HGMERGE environment variable and your configuration files. See
hg help merge-tools for options.
If no revision is specified, the working directory's parent is a head revision,
and the current branch contains exactly one other head, the other head is
merged with by default. Otherwise, an explicit revision with which to merge
with must be provided.
hg resolve must be used to resolve unresolved files.
To undo an uncommitted merge, use
hg update --clean . which will check
out a clean copy of the original merge parent, losing all changes.
Returns 0 on success, 1 if there are unresolved files.
Options:
- -f, --force
- force a merge including outstanding changes
(DEPRECATED)
- -r,--rev <REV>
- revision to merge
- -P, --preview
- review revisions to merge (no merge is performed)
- -t,--tool <VALUE>
- specify merge tool
outgoing¶
show changesets not found in the destination:
hg outgoing [-M] [-p] [-n] [-f] [-r REV]... [DEST]
Show changesets not found in the specified destination repository or the default
push location. These are the changesets that would be pushed if a push was
requested.
See pull for details of valid destination formats.
Returns 0 if there are outgoing changes, 1 otherwise.
Options:
- -f, --force
- run even when the destination is unrelated
- -r,--rev <REV[+]>
- a changeset intended to be included in the destination

[+] marked option can be specified multiple times
parents¶
show the parents of the working directory or revision:
hg parents [-r REV] [FILE]
Print the working directory's parent revisions. If a revision is given via
-r/--rev, the parent of that revision will be printed. If a file argument is
given, the revision in which the file was last changed (before the working
directory revision or the argument to --rev if given) is printed.
Returns 0 on success.
Options:
- -r,--rev <REV>
- show parents of the specified revision
- --style <STYLE>
- display using template map file (DEPRECATED)
- -T,--template <TEMPLATE>
- display with template
paths¶
show aliases for remote repositories:
hg paths [NAME]
Show definition of symbolic path name NAME. If no name is given, show definition
of all available names.
Option -q/--quiet suppresses all output when searching for NAME and shows only
the path names when listing all definitions.
Path names are defined in the [paths] section of your configuration file and in
/etc/mercurial/hgrc. If run inside a repository,
.hg/hgrc is
used, too.
The path names
default and
default-push have a special meaning.
When performing a push or pull operation, they are used as fallbacks if no
location is specified on the command-line. When
default-push is set, it
will be used for push and
default will be used for pull; otherwise
default is used as the fallback for both. When cloning a repository,
the clone source is written as
default in
.hg/hgrc. Note that
default and
default-push apply to all inbound (e.g.
hg
incoming) and outbound (e.g.
hg outgoing,
hg email and
hg
bundle) operations.
See
hg help urls for more information.
Returns 0 on success.
phase¶
set or show the current phase name:
hg phase [-p|-d|-s] [-f] [-r] REV...
With no argument, show the phase name of specified revisions.
With one of -p/--public, -d/--draft or -s/--secret, change the phase value of
the specified revisions.
Unless -f/--force is specified,
hg phase won't move changeset from a
lower phase to an higher phase. Phases are ordered as follows:
public < draft < secret
Returns 0 on success, 1 if no phases were changed or some could not be changed.
Options:
- -p, --public
- set changeset phase to public
- -d, --draft
- set changeset phase to draft
- -s, --secret
- set changeset phase to secret
- -f, --force
- allow to move boundary backward
- -r,--rev <REV[+]>
- target revision
[+] marked option can be specified multiple times
pull¶
pull changes from the specified source:
hg pull [-u] [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [SOURCE]
Pull changes from a remote repository to a local one.
This finds all changes from the repository at the specified path or URL and adds
them to a local repository (the current one unless -R is specified). By
default, this does not update the copy of the project in the working
directory.
Use
hg incoming if you want to see what would have been added by a pull
at the time you issued this command. If you then decide to add those changes
to the repository, you should use
hg pull -r X where
X is
the last changeset listed by
hg incoming.
If SOURCE is omitted, the 'default' path will be used. See
hg help urls
for more information.
Returns 0 on success, 1 if an update had unresolved files.
Options:
- -u, --update
- update to new branch head if changesets were pulled
- -f, --force
- run even when remote repository is unrelated
- -r,--rev <REV[+]>
- a remote changeset intended to be added
- -B,--bookmark <BOOKMARK[+]>
- bookmark to pull
- -b,--branch <BRANCH[+]>
- a specific branch you would like to pull
- -e,--ssh <CMD>
- specify ssh command to use
- --remotecmd <CMD>
- specify hg command to run on the remote side
- --insecure
- do not verify server certificate (ignoring web.cacerts
config)
[+] marked option can be specified multiple times
push¶
push changes to the specified destination:
hg push [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [DEST]
Push changesets from the local repository to the specified destination.
This operation is symmetrical to pull: it is identical to a pull in the
destination repository from the current one.
By default, push will not allow creation of new heads at the destination, since
multiple heads would make it unclear which head to use. In this situation, it
is recommended to pull and merge before pushing.
Use --new-branch if you want to allow push to create a new named branch that is
not present at the destination. This allows you to only create a new branch
without forcing other changes.
- Note
- Extra care should be taken with the -f/--force option,
which will push all new heads on all branches, an action which will almost
always cause confusion for collaborators.
If -r/--rev is used, the specified revision and all its ancestors will be pushed
to the remote repository.
If -B/--bookmark is used, the specified bookmarked revision, its ancestors, and
the bookmark will be pushed to the remote repository.
Please see
hg help urls for important details about
ssh:// URLs.
If DESTINATION is omitted, a default path will be used.
Returns 0 if push was successful, 1 if nothing to push.
Options:
- -f, --force
- force push
- -r,--rev <REV[+]>
- a changeset intended to be included in the destination
- -B,--bookmark <BOOKMARK[+]>
- bookmark to push
- -b,--branch <BRANCH[+]>
- a specific branch you would like to push
- --new-branch
- allow pushing a new branch
- -e,--ssh <CMD>
- specify ssh command to use
- --remotecmd <CMD>
- specify hg command to run on the remote side
- --insecure
- do not verify server certificate (ignoring web.cacerts
config)
[+] marked option can be specified multiple times
recover¶
roll back an interrupted transaction:
hg recover
Recover from an interrupted commit or pull.
This command tries to fix the repository status after an interrupted operation.
It should only be necessary when Mercurial suggests it.
Returns 0 if successful, 1 if nothing to recover or verify fails.
remove¶
remove the specified files on the next commit:
hg remove [OPTION]... FILE...
Schedule the indicated files for removal from the current branch.
This command schedules the files to be removed at the next commit. To undo a
remove before that, see
hg revert. To undo added files, see
hg
forget.
-A/--after can be used to remove only files that have already been deleted,
-f/--force can be used to force deletion, and -Af can be used to remove files
from the next revision without deleting them from the working directory.
The following table details the behavior of remove for different file states
(columns) and option combinations (rows). The file states are Added [A], Clean
[C], Modified [M] and Missing [!] (as reported by
hg status). The
actions are Warn, Remove (from branch) and Delete (from disk):
|
opt/state |
A |
C |
M |
! |
|
none |
W |
RD |
W |
R |

Note that remove never deletes files in Added [A] state from the working
directory, not even if option --force is specified.
Returns 0 on success, 1 if any warnings encountered.
Options:
- -A, --after
- record delete for missing files
- -f, --force
- remove (and delete) file even if added or modified
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
rename¶
rename files; equivalent of copy + remove:
hg rename [OPTION]... SOURCE... DEST
Mark dest as copies of sources; mark sources for deletion. If dest is a
directory, copies are put in that directory. If dest is a file, there can only
be one source.
By default, this command copies the contents of files as they exist in the
working directory. If invoked with -A/--after, the operation is recorded, but
no copying is performed.
This command takes effect at the next commit. To undo a rename before that, see
hg revert.
Returns 0 on success, 1 if errors are encountered.
Options:
- -A, --after
- record a rename that has already occurred
- -f, --force
- forcibly copy over an existing managed file
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
- -n, --dry-run
- do not perform actions, just print output
[+] marked option can be specified multiple times
resolve¶
redo merges or set/view the merge status of files:
hg resolve [OPTION]... [FILE]...
Merges with unresolved conflicts are often the result of non-interactive merging
using the
internal:merge configuration setting, or a command-line merge
tool like
diff3. The resolve command is used to manage the files
involved in a merge, after
hg merge has been run, and before
hg
commit is run (i.e. the working directory must have two parents). See
hg help merge-tools for information on configuring merge tools.
The resolve command can be used in the following ways:
- •
- hg resolve [--tool TOOL] FILE...: attempt to
re-merge the specified files, discarding any previous merge attempts.
Re-merging is not performed for files already marked as resolved. Use
--all/-a to select all unresolved files. --tool can be used
to specify the merge tool used for the given files. It overrides the
HGMERGE environment variable and your configuration files. Previous file
contents are saved with a .orig suffix.
- •
- hg resolve -m [FILE]: mark a file as having been
resolved (e.g. after having manually fixed-up the files). The default is
to mark all unresolved files.
- •
- hg resolve -u [FILE]...: mark a file as unresolved.
The default is to mark all resolved files.
- •
- hg resolve -l: list files which had or still have
conflicts. In the printed list, U = unresolved and R =
resolved.
Note that Mercurial will not let you commit files with unresolved merge
conflicts. You must use
hg resolve -m ... before you can commit after a
conflicting merge.
Returns 0 on success, 1 if any files fail a resolve attempt.
Options:
- -a, --all
- select all unresolved files
- -l, --list
- list state of files needing merge
- -m, --mark
- mark files as resolved
- -u, --unmark
- mark files as unresolved
- -n, --no-status
- hide status prefix
- -t,--tool <VALUE>
- specify merge tool
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
revert¶
restore files to their checkout state:
hg revert [OPTION]... [-r REV] [NAME]...
- Note
- To check out earlier revisions, you should use hg update
REV. To cancel an uncommitted merge (and lose your changes), use hg
update --clean ..
With no revision specified, revert the specified files or directories to the
contents they had in the parent of the working directory. This restores the
contents of files to an unmodified state and unschedules adds, removes,
copies, and renames. If the working directory has two parents, you must
explicitly specify a revision.
Using the -r/--rev or -d/--date options, revert the given files or directories
to their states as of a specific revision. Because revert does not change the
working directory parents, this will cause these files to appear modified.
This can be helpful to "back out" some or all of an earlier change.
See
hg backout for a related method.
Modified files are saved with a .orig suffix before reverting. To disable these
backups, use --no-backup.
See
hg help dates for a list of formats valid for -d/--date.
Returns 0 on success.
Options:
- -a, --all
- revert all changes when no arguments given
- -d,--date <DATE>
- tipmost revision matching date
- -r,--rev <REV>
- revert to the specified revision
- -C, --no-backup
- do not save backup copies of files
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
- -n, --dry-run
- do not perform actions, just print output
[+] marked option can be specified multiple times
rollback¶
roll back the last transaction (DANGEROUS) (DEPRECATED):
hg rollback
Please use
hg commit --amend instead of rollback to correct mistakes in
the last commit.
This command should be used with care. There is only one level of rollback, and
there is no way to undo a rollback. It will also restore the dirstate at the
time of the last transaction, losing any dirstate changes since that time.
This command does not alter the working directory.
Transactions are used to encapsulate the effects of all commands that create new
changesets or propagate existing changesets into a repository.
For example, the following commands are transactional, and their effects can be
rolled back:
- •
- commit
- •
- import
- •
- pull
- •
- push (with this repository as the destination)
- •
- unbundle
To avoid permanent data loss, rollback will refuse to rollback a commit
transaction if it isn't checked out. Use --force to override this protection.
This command is not intended for use on public repositories. Once changes are
visible for pull by other users, rolling a transaction back locally is
ineffective (someone else may already have pulled the changes). Furthermore, a
race is possible with readers of the repository; for example an in-progress
pull from the repository may fail if a rollback is performed.
Returns 0 on success, 1 if no rollback data is available.
Options:
- -n, --dry-run
- do not perform actions, just print output
- -f, --force
- ignore safety measures
root¶
print the root (top) of the current working directory:
hg root
Print the root directory of the current repository.
Returns 0 on success.
serve¶
start stand-alone webserver:
hg serve [OPTION]...
Start a local HTTP repository browser and pull server. You can use this for
ad-hoc sharing and browsing of repositories. It is recommended to use a real
web server to serve a repository for longer periods of time.
Please note that the server does not implement access control. This means that,
by default, anybody can read from the server and nobody can write to it by
default. Set the
web.allow_push option to
* to allow everybody
to push to the server. You should use a real web server if you need to
authenticate users.
By default, the server logs accesses to stdout and errors to stderr. Use the
-A/--accesslog and -E/--errorlog options to log to files.
To have the server choose a free port number to listen on, specify a port number
of 0; in this case, the server will print the port number it uses.
Returns 0 on success.
Options:
- -A,--accesslog <FILE>
- name of access log file to write to
- -d, --daemon
- run server in background
- --daemon-pipefds <NUM>
- used internally by daemon mode
- -E,--errorlog <FILE>
- name of error log file to write to
- -p,--port <PORT>
- port to listen on (default: 8000)
- -a,--address <ADDR>
- address to listen on (default: all interfaces)
- --prefix <PREFIX>
- prefix path to serve from (default: server root)
- -n,--name <NAME>
- name to show in web pages (default: working directory)
- --web-conf <FILE>
- name of the hgweb config file (see "hg help
hgweb")
- --webdir-conf <FILE>
- name of the hgweb config file (DEPRECATED)
- --pid-file <FILE>
- name of file to write process ID to
- --stdio
- for remote clients
- --cmdserver <MODE>
- for remote clients
- -t,--templates <TEMPLATE>
- web templates to use
- --style <STYLE>
- template style to use
- -6, --ipv6
- use IPv6 in addition to IPv4
- --certificate <FILE>
- SSL certificate file
status¶
show changed files in the working directory:
hg status [OPTION]... [FILE]...
Show status of files in the repository. If names are given, only files that
match are shown. Files that are clean or ignored or the source of a copy/move
operation, are not listed unless -c/--clean, -i/--ignored, -C/--copies or
-A/--all are given. Unless options described with "show only ..."
are given, the options -mardu are used.
Option -q/--quiet hides untracked (unknown and ignored) files unless explicitly
requested with -u/--unknown or -i/--ignored.
- Note
- status may appear to disagree with diff if permissions have
changed or a merge has occurred. The standard diff format does not report
permission changes and diff only reports changes relative to one merge
parent.
If one revision is given, it is used as the base revision. If two revisions are
given, the differences between them are shown. The --change option can also be
used as a shortcut to list the changed files of a revision from its first
parent.
The codes used to show the status of files are:
M = modified
A = added
R = removed
C = clean
! = missing (deleted by non-hg command, but still tracked)
? = not tracked
I = ignored
= origin of the previous file (with --copies)
Examples:
- •
- show changes in the working directory relative to a
changeset:
hg status --rev 9353
- •
- show all changes including copies in an existing changeset:
hg status --copies --change 9353
- •
- get a NUL separated list of added files, suitable for
xargs:
hg status -an0
Returns 0 on success.
Options:
- -A, --all
- show status of all files
- -m, --modified
- show only modified files
- -a, --added
- show only added files
- -r, --removed
- show only removed files
- -d, --deleted
- show only deleted (but tracked) files
- -c, --clean
- show only files without changes
- -u, --unknown
- show only unknown (not tracked) files
- -i, --ignored
- show only ignored files
- -n, --no-status
- hide status prefix
- -C, --copies
- show source of copied files
- -0, --print0
- end filenames with NUL, for use with xargs
- --rev <REV[+]>
- show difference from revision
- --change <REV>
- list the changed files of a revision
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
- -S, --subrepos
- recurse into subrepositories
[+] marked option can be specified multiple times
summary¶
summarize working directory state:
hg summary [--remote]
This generates a brief summary of the working directory state, including
parents, branch, commit status, and available updates.
With the --remote option, this will check the default paths for incoming and
outgoing changes. This can be time-consuming.
Returns 0 on success.
Options:
- --remote
- check for push and pull
aliases: sum
tag¶
add one or more tags for the current or given revision:
hg tag [-f] [-l] [-m TEXT] [-d DATE] [-u USER] [-r REV] NAME...
Name a particular revision using <name>.
Tags are used to name particular revisions of the repository and are very useful
to compare different revisions, to go back to significant earlier versions or
to mark branch points as releases, etc. Changing an existing tag is normally
disallowed; use -f/--force to override.
If no revision is given, the parent of the working directory is used.
To facilitate version control, distribution, and merging of tags, they are
stored as a file named ".hgtags" which is managed similarly to other
project files and can be hand-edited if necessary. This also means that
tagging creates a new commit. The file ".hg/localtags" is used for
local tags (not shared among repositories).
Tag commits are usually made at the head of a branch. If the parent of the
working directory is not a branch head,
hg tag aborts; use -f/--force
to force the tag commit to be based on a non-head changeset.
See
hg help dates for a list of formats valid for -d/--date.
Since tag names have priority over branch names during revision lookup, using an
existing branch name as a tag name is discouraged.
Returns 0 on success.
Options:
- -f, --force
- force tag
- -l, --local
- make the tag local
- -r,--rev <REV>
- revision to tag
- --remove
- remove a tag
- -e, --edit
- invoke editor on commit messages
- -m,--message <TEXT>
- use text as commit message
- -d,--date <DATE>
- record the specified date as commit date
- -u,--user <USER>
- record the specified user as committer
list repository tags:
hg tags
This lists both regular and local tags. When the -v/--verbose switch is used, a
third column "local" is printed for local tags.
Returns 0 on success.
tip¶
show the tip revision (DEPRECATED):
hg tip [-p] [-g]
The tip revision (usually just called the tip) is the changeset most recently
added to the repository (and therefore the most recently changed head).
If you have just made a commit, that commit will be the tip. If you have just
pulled changes from another repository, the tip of that repository becomes the
current tip. The "tip" tag is special and cannot be renamed or
assigned to a different changeset.
This command is deprecated, please use
hg heads instead.
Returns 0 on success.
Options:
- -p, --patch
- show patch
- -g, --git
- use git extended diff format
- --style <STYLE>
- display using template map file (DEPRECATED)
- -T,--template <TEMPLATE>
- display with template
unbundle¶
apply one or more changegroup files:
hg unbundle [-u] FILE...
Apply one or more compressed changegroup files generated by the bundle command.
Returns 0 on success, 1 if an update has unresolved files.
Options:
- -u, --update
- update to new branch head if changesets were unbundled
update¶
update working directory (or switch revisions):
hg update [-c] [-C] [-d DATE] [[-r] REV]
Update the repository's working directory to the specified changeset. If no
changeset is specified, update to the tip of the current named branch and move
the current bookmark (see
hg help bookmarks).
Update sets the working directory's parent revision to the specified changeset
(see
hg help parents).
If the changeset is not a descendant or ancestor of the working directory's
parent, the update is aborted. With the -c/--check option, the working
directory is checked for uncommitted changes; if none are found, the working
directory is updated to the specified changeset.
The following rules apply when the working directory contains uncommitted
changes:
- 1.
- If neither -c/--check nor -C/--clean is specified, and if
the requested changeset is an ancestor or descendant of the working
directory's parent, the uncommitted changes are merged into the requested
changeset and the merged result is left uncommitted. If the requested
changeset is not an ancestor or descendant (that is, it is on another
branch), the update is aborted and the uncommitted changes are
preserved.
- 2.
- With the -c/--check option, the update is aborted and the
uncommitted changes are preserved.
- 3.
- With the -C/--clean option, uncommitted changes are
discarded and the working directory is updated to the requested
changeset.
To cancel an uncommitted merge (and lose your changes), use
hg update --clean
..
Use null as the changeset to remove the working directory (like
hg clone
-U).
If you want to revert just one file to an older revision, use
hg revert [-r
REV] NAME.
See
hg help dates for a list of formats valid for -d/--date.
Returns 0 on success, 1 if there are unresolved files.
Options:
- -C, --clean
- discard uncommitted changes (no backup)
- -c, --check
- update across branches if no uncommitted changes
- -d,--date <DATE>
- tipmost revision matching date
- -r,--rev <REV>
- revision
- -t,--tool <VALUE>
- specify merge tool
aliases: up checkout co
verify¶
verify the integrity of the repository:
hg verify
Verify the integrity of the current repository.
This will perform an extensive check of the repository's integrity, validating
the hashes and checksums of each entry in the changelog, manifest, and tracked
files, as well as the integrity of their crosslinks and indices.
Please see
http://mercurial.selenic.com/wiki/RepositoryCorruption for more
information about recovery from corruption of the repository.
Returns 0 on success, 1 if errors are encountered.
version¶
output version and copyright information:
hg version
output version and copyright information
Some commands allow the user to specify a date, e.g.:
- •
- backout, commit, import, tag: Specify the commit date.
- •
- log, revert, update: Select revision(s) by date.
Many date formats are valid. Here are some examples:
- •
- Wed Dec 6 13:18:29 2006 (local timezone
assumed)
- •
- Dec 6 13:18 -0600 (year assumed, time offset
provided)
- •
- Dec 6 13:18 UTC (UTC and GMT are aliases for
+0000)
- •
- Dec 6 (midnight)
- •
- 13:18 (today assumed)
- •
- 3:39 (3:39AM assumed)
- •
- 3:39pm (15:39)
- •
- 2006-12-06 13:18:29 (ISO 8601 format)
- •
- 2006-12-6 13:18
- •
- 2006-12-6
- •
- 12-6
- •
- 12/6
- •
- 12/6/6 (Dec 6 2006)
- •
- today (midnight)
- •
- yesterday (midnight)
- •
- now - right now
Lastly, there is Mercurial's internal format:
- •
- 1165411109 0 (Wed Dec 6 13:18:29 2006 UTC)
This is the internal representation format for dates. The first number is the
number of seconds since the epoch (1970-01-01 00:00 UTC). The second is the
offset of the local timezone, in seconds west of UTC (negative if the timezone
is east of UTC).
The log command also accepts date ranges:
- •
- <DATE - at or before a given date/time
- •
- >DATE - on or after a given date/time
- •
- DATE to DATE - a date range, inclusive
- •
- -DAYS - within a given number of days of today
Mercurial's default format for showing changes between two versions of a file is
compatible with the unified format of GNU diff, which can be used by GNU patch
and many other standard tools.
While this standard format is often enough, it does not encode the following
information:
- •
- executable status and other permission bits
- •
- copy or rename information
- •
- changes in binary files
- •
- creation or deletion of empty files
Mercurial also supports the extended diff format from the git VCS which
addresses these limitations. The git diff format is not produced by default
because a few widespread tools still do not understand this format.
This means that when generating diffs from a Mercurial repository (e.g. with
hg export), you should be careful about things like file copies and
renames or other things mentioned above, because when applying a standard diff
to a different repository, this extra information is lost. Mercurial's
internal operations (like push and pull) are not affected by this, because
they use an internal binary format for communicating changes.
To make Mercurial produce the git extended diff format, use the --git option
available for many commands, or set 'git = True' in the [diff] section of your
configuration file. You do not need to set this option when importing diffs in
this format or using them in the mq extension.
ENVIRONMENT VARIABLES¶
- HG
- Path to the 'hg' executable, automatically passed when
running hooks, extensions or external tools. If unset or empty, this is
the hg executable's name if it's frozen, or an executable named 'hg' (with
%PATHEXT% [defaulting to COM/EXE/BAT/CMD] extensions on Windows) is
searched.
- HGEDITOR
- This is the name of the editor to run when committing. See
EDITOR.
(deprecated, use configuration file)
- HGENCODING
- This overrides the default locale setting detected by
Mercurial. This setting is used to convert data including usernames,
changeset descriptions, tag names, and branches. This setting can be
overridden with the --encoding command-line option.
- HGENCODINGMODE
- This sets Mercurial's behavior for handling unknown
characters while transcoding user input. The default is
"strict", which causes Mercurial to abort if it can't map a
character. Other settings include "replace", which replaces
unknown characters, and "ignore", which drops them. This setting
can be overridden with the --encodingmode command-line option.
- HGENCODINGAMBIGUOUS
- This sets Mercurial's behavior for handling characters with
"ambiguous" widths like accented Latin characters with East
Asian fonts. By default, Mercurial assumes ambiguous characters are
narrow, set this variable to "wide" if such characters cause
formatting problems.
- HGMERGE
- An executable to use for resolving merge conflicts. The
program will be executed with three arguments: local file, remote file,
ancestor file.
(deprecated, use configuration file)
- HGRCPATH
- A list of files or directories to search for configuration
files. Item separator is ":" on Unix, ";" on Windows.
If HGRCPATH is not set, platform default search path is used. If empty,
only the .hg/hgrc from the current repository is read.
For each element in HGRCPATH:
- •
- if it's a directory, all files ending with .rc are
added
- •
- otherwise, the file itself will be added
- HGPLAIN
- When set, this disables any configuration settings that
might change Mercurial's default output. This includes encoding, defaults,
verbose mode, debug mode, quiet mode, tracebacks, and localization. This
can be useful when scripting against Mercurial in the face of existing
user configuration.
Equivalent options set via command line flags or environment variables are
not overridden.
- HGPLAINEXCEPT
- This is a comma-separated list of features to preserve when
HGPLAIN is enabled. Currently the only value supported is
"i18n", which preserves internationalization in plain mode.
Setting HGPLAINEXCEPT to anything (even an empty string) will enable plain
mode.
- HGUSER
- This is the string used as the author of a commit. If not
set, available values will be considered in this order:
- •
- HGUSER (deprecated)
- •
- configuration files from the HGRCPATH
- •
- EMAIL
- •
- interactive prompt
- •
- LOGNAME (with @hostname appended)
(deprecated, use configuration file)
- EMAIL
- May be used as the author of a commit; see HGUSER.
- LOGNAME
- May be used as the author of a commit; see HGUSER.
- VISUAL
- This is the name of the editor to use when committing. See
EDITOR.
- EDITOR
- Sometimes Mercurial needs to open a text file in an editor
for a user to modify, for example when writing commit messages. The editor
it uses is determined by looking at the environment variables HGEDITOR,
VISUAL and EDITOR, in that order. The first non-empty one is chosen. If
all of them are empty, the editor defaults to 'sensible-editor'.
- PYTHONPATH
- This is used by Python to find imported modules and may
need to be set appropriately if this Mercurial is not installed
system-wide.
USING ADDITIONAL FEATURES¶
Mercurial has the ability to add new features through the use of extensions.
Extensions may add new commands, add options to existing commands, change the
default behavior of commands, or implement hooks.
To enable the "foo" extension, either shipped with Mercurial or in the
Python search path, create an entry for it in your configuration file, like
this:
[extensions]
foo =
You may also specify the full path to an extension:
[extensions]
myfeature = ~/.hgext/myfeature.py
See
hg help config for more information on configuration files.
Extensions are not loaded by default for a variety of reasons: they can increase
startup overhead; they may be meant for advanced usage only; they may provide
potentially dangerous abilities (such as letting you destroy or modify
history); they might not be ready for prime time; or they may alter some usual
behaviors of stock Mercurial. It is thus up to the user to activate extensions
as needed.
To explicitly disable an extension enabled in a configuration file of broader
scope, prepend its path with !:
[extensions]
# disabling extension bar residing in /path/to/extension/bar.py
bar = !/path/to/extension/bar.py
# ditto, but no path was supplied for extension baz
baz = !

SPECIFYING FILE SETS¶
Mercurial supports a functional language for selecting a set of files.
Like other file patterns, this pattern type is indicated by a prefix, 'set:'.
The language supports a number of predicates which are joined by infix
operators. Parenthesis can be used for grouping.
Identifiers such as filenames or patterns must be quoted with single or double
quotes if they contain characters outside of
[.*{}[]?/\_a-zA-Z0-9\x80-\xff] or if they match one of the predefined
predicates. This generally applies to file patterns other than globs and
arguments for predicates.
Special characters can be used in quoted identifiers by escaping them, e.g.,
\n is interpreted as a newline. To prevent them from being interpreted,
strings can be prefixed with
r, e.g.
r'...'.
There is a single prefix operator:
- not x
-
Files not in x. Short form is ! x.
These are the supported infix operators:
- x and y
-
The intersection of files in x and y. Short form is x & y.
- x or y
-
The union of files in x and y. There are two alternative short forms: x |
y and x + y.
- x - y
-
Files in x but not in y.
The following predicates are supported:
- added()
-
File that is added according to status.
- binary()
-
File that appears to be binary (contains NUL bytes).
- clean()
-
File that is clean according to status.
- copied()
-
File that is recorded as being copied.
- deleted()
-
File that is deleted according to status.
- encoding(name)
-
File can be successfully decoded with the given character encoding. May not
be useful for encodings other than ASCII and UTF-8.
- eol(style)
-
File contains newlines of the given style (dos, unix, mac). Binary files are
excluded, files with mixed line endings match multiple styles.
- exec()
-
File that is marked as executable.
- grep(regex)
-
File contains the given regular expression.
- hgignore()
-
File that matches the active .hgignore pattern.
- ignored()
-
File that is ignored according to status. These files will only be
considered if this predicate is used.
- modified()
-
File that is modified according to status.
- removed()
-
File that is removed according to status.
- resolved()
-
File that is marked resolved according to the resolve state.
- size(expression)
-
File size matches the given expression. Examples:
- •
- 1k (files from 1024 to 2047 bytes)
- •
- < 20k (files less than 20480 bytes)
- •
- >= .5MB (files at least 524288 bytes)
- •
- 4k - 1MB (files from 4096 bytes to 1048576 bytes)
- subrepo([pattern])
-
Subrepositories whose paths match the given pattern.
- symlink()
-
File that is marked as a symlink.
- unknown()
-
File that is unknown according to status. These files will only be
considered if this predicate is used.
- unresolved()
-
File that is marked unresolved according to the resolve state.
Some sample queries:
- •
- Show status of files that appear to be binary in the
working directory:
hg status -A "set:binary()"
- •
- Forget files that are in .hgignore but are already tracked:
hg forget "set:hgignore() and not ignored()"
- •
- Find text files that contain a string:
hg locate "set:grep(magic) and not binary()"
- •
- Find C files in a non-standard encoding:
hg locate "set:**.c and not encoding('UTF-8')"
- •
- Revert copies of large binary files:
hg revert "set:copied() and binary() and size('>1M')"
- •
- Remove files listed in foo.lst that contain the letter a or
b:
hg remove "set: 'listfile:foo.lst' and (**a* or **b*)"

GLOSSARY¶
- Ancestor
- Any changeset that can be reached by an unbroken chain of
parent changesets from a given changeset. More precisely, the ancestors of
a changeset can be defined by two properties: a parent of a changeset is
an ancestor, and a parent of an ancestor is an ancestor. See also:
'Descendant'.
- Bookmark
- Bookmarks are pointers to certain commits that move when
committing. They are similar to tags in that it is possible to use
bookmark names in all places where Mercurial expects a changeset ID, e.g.,
with hg update. Unlike tags, bookmarks move along when you make a
commit.
Bookmarks can be renamed, copied and deleted. Bookmarks are local, unless
they are explicitly pushed or pulled between repositories. Pushing and
pulling bookmarks allow you to collaborate with others on a branch without
creating a named branch.
- Branch
- (Noun) A child changeset that has been created from a
parent that is not a head. These are known as topological branches, see
'Branch, topological'. If a topological branch is named, it becomes a
named branch. If a topological branch is not named, it becomes an
anonymous branch. See 'Branch, anonymous' and 'Branch, named'.
Branches may be created when changes are pulled from or pushed to a remote
repository, since new heads may be created by these operations. Note that
the term branch can also be used informally to describe a development
process in which certain development is done independently of other
development. This is sometimes done explicitly with a named branch, but it
can also be done locally, using bookmarks or clones and anonymous
branches.
Example: "The experimental branch".
(Verb) The action of creating a child changeset which results in its parent
having more than one child.
Example: "I'm going to branch at X".
- Branch, anonymous
- Every time a new child changeset is created from a parent
that is not a head and the name of the branch is not changed, a new
anonymous branch is created.
- Branch, closed
- A named branch whose branch heads have all been
closed.
- Branch, default
- The branch assigned to a changeset when no name has
previously been assigned.
- Branch head
- See 'Head, branch'.
- Branch, inactive
- If a named branch has no topological heads, it is
considered to be inactive. As an example, a feature branch becomes
inactive when it is merged into the default branch. The hg branches
command shows inactive branches by default, though they can be hidden with
hg branches --active.
NOTE: this concept is deprecated because it is too implicit. Branches should
now be explicitly closed using hg commit --close-branch when
they are no longer needed.
- Branch, named
- A collection of changesets which have the same branch name.
By default, children of a changeset in a named branch belong to the same
named branch. A child can be explicitly assigned to a different branch.
See hg help branch, hg help branches and hg commit
--close-branch for more information on managing branches.
Named branches can be thought of as a kind of namespace, dividing the
collection of changesets that comprise the repository into a collection of
disjoint subsets. A named branch is not necessarily a topological branch.
If a new named branch is created from the head of another named branch, or
the default branch, but no further changesets are added to that previous
branch, then that previous branch will be a branch in name only.
- Branch tip
- See 'Tip, branch'.
- Branch, topological
- Every time a new child changeset is created from a parent
that is not a head, a new topological branch is created. If a topological
branch is named, it becomes a named branch. If a topological branch is not
named, it becomes an anonymous branch of the current, possibly default,
branch.
- Changelog
- A record of the changesets in the order in which they were
added to the repository. This includes details such as changeset id,
author, commit message, date, and list of changed files.
- Changeset
- A snapshot of the state of the repository used to record a
change.
- Changeset, child
- The converse of parent changeset: if P is a parent of C,
then C is a child of P. There is no limit to the number of children that a
changeset may have.
- Changeset id
- A SHA-1 hash that uniquely identifies a changeset. It may
be represented as either a "long" 40 hexadecimal digit string,
or a "short" 12 hexadecimal digit string.
- Changeset, merge
- A changeset with two parents. This occurs when a merge is
committed.
- Changeset, parent
- A revision upon which a child changeset is based.
Specifically, a parent changeset of a changeset C is a changeset whose
node immediately precedes C in the DAG. Changesets have at most two
parents.
- Checkout
- (Noun) The working directory being updated to a specific
revision. This use should probably be avoided where possible, as changeset
is much more appropriate than checkout in this context.
Example: "I'm using checkout X."
(Verb) Updating the working directory to a specific changeset. See hg
help update.
Example: "I'm going to check out changeset X."
- Child changeset
- See 'Changeset, child'.
- Close changeset
- See 'Head, closed branch'
- Closed branch
- See 'Branch, closed'.
- Clone
- (Noun) An entire or partial copy of a repository. The
partial clone must be in the form of a revision and its ancestors.
Example: "Is your clone up to date?".
(Verb) The process of creating a clone, using hg clone.
Example: "I'm going to clone the repository".
- Closed branch head
- See 'Head, closed branch'.
- Commit
- (Noun) A synonym for changeset.
Example: "Is the bug fixed in your recent commit?"
(Verb) The act of recording changes to a repository. When files are
committed in a working directory, Mercurial finds the differences between
the committed files and their parent changeset, creating a new changeset
in the repository.
Example: "You should commit those changes now."
- Cset
- A common abbreviation of the term changeset.
- DAG
- The repository of changesets of a distributed version
control system (DVCS) can be described as a directed acyclic graph (DAG),
consisting of nodes and edges, where nodes correspond to changesets and
edges imply a parent -> child relation. This graph can be visualized by
graphical tools such as hg log --graph. In Mercurial, the DAG is
limited by the requirement for children to have at most two parents.
- Default branch
- See 'Branch, default'.
- Descendant
- Any changeset that can be reached by a chain of child
changesets from a given changeset. More precisely, the descendants of a
changeset can be defined by two properties: the child of a changeset is a
descendant, and the child of a descendant is a descendant. See also:
'Ancestor'.
- Diff
- (Noun) The difference between the contents and attributes
of files in two changesets or a changeset and the current working
directory. The difference is usually represented in a standard form called
a "diff" or "patch". The "git diff" format
is used when the changes include copies, renames, or changes to file
attributes, none of which can be represented/handled by classic
"diff" and "patch".
Example: "Did you see my correction in the diff?"
(Verb) Diffing two changesets is the action of creating a diff or patch.
Example: "If you diff with changeset X, you will see what I
mean."
- Directory, working
- The working directory represents the state of the files
tracked by Mercurial, that will be recorded in the next commit. The
working directory initially corresponds to the snapshot at an existing
changeset, known as the parent of the working directory. See 'Parent,
working directory'. The state may be modified by changes to the files
introduced manually or by a merge. The repository metadata exists in the
.hg directory inside the working directory.
- Draft
- Changesets in the draft phase have not been shared with
publishing repositories and may thus be safely changed by
history-modifying extensions. See hg help phases.
- Graph
- See DAG and hg log --graph.
- Head
- The term 'head' may be used to refer to both a branch head
or a repository head, depending on the context. See 'Head, branch' and
'Head, repository' for specific definitions.
Heads are where development generally takes place and are the usual targets
for update and merge operations.
- Head, branch
- A changeset with no descendants on the same named
branch.
- Head, closed branch
- A changeset that marks a head as no longer interesting. The
closed head is no longer listed by hg heads. A branch is considered
closed when all its heads are closed and consequently is not listed by
hg branches.
Closed heads can be re-opened by committing new changeset as the child of
the changeset that marks a head as closed.
- Head, repository
- A topological head which has not been closed.
- Head, topological
- A changeset with no children in the repository.
- History, immutable
- Once committed, changesets cannot be altered. Extensions
which appear to change history actually create new changesets that replace
existing ones, and then destroy the old changesets. Doing so in public
repositories can result in old changesets being reintroduced to the
repository.
- History, rewriting
- The changesets in a repository are immutable. However,
extensions to Mercurial can be used to alter the repository, usually in
such a way as to preserve changeset contents.
- Immutable history
- See 'History, immutable'.
- Merge changeset
- See 'Changeset, merge'.
- Manifest
- Each changeset has a manifest, which is the list of files
that are tracked by the changeset.
- Merge
- Used to bring together divergent branches of work. When you
update to a changeset and then merge another changeset, you bring the
history of the latter changeset into your working directory. Once
conflicts are resolved (and marked), this merge may be committed as a
merge changeset, bringing two branches together in the DAG.
- Named branch
- See 'Branch, named'.
- Null changeset
- The empty changeset. It is the parent state of
newly-initialized repositories and repositories with no checked out
revision. It is thus the parent of root changesets and the effective
ancestor when merging unrelated changesets. Can be specified by the alias
'null' or by the changeset ID '000000000000'.
- Parent
- See 'Changeset, parent'.
- Parent changeset
- See 'Changeset, parent'.
- Parent, working directory
- The working directory parent reflects a virtual revision
which is the child of the changeset (or two changesets with an uncommitted
merge) shown by hg parents. This is changed with hg update.
Other commands to see the working directory parent are hg summary
and hg id. Can be specified by the alias ".".
- Patch
- (Noun) The product of a diff operation.
Example: "I've sent you my patch."
(Verb) The process of using a patch file to transform one changeset into
another.
Example: "You will need to patch that revision."
- Phase
- A per-changeset state tracking how the changeset has been
or should be shared. See hg help phases.
- Public
- Changesets in the public phase have been shared with
publishing repositories and are therefore considered immutable. See hg
help phases.
- Pull
- An operation in which changesets in a remote repository
which are not in the local repository are brought into the local
repository. Note that this operation without special arguments only
updates the repository, it does not update the files in the working
directory. See hg help pull.
- Push
- An operation in which changesets in a local repository
which are not in a remote repository are sent to the remote repository.
Note that this operation only adds changesets which have been committed
locally to the remote repository. Uncommitted changes are not sent. See
hg help push.
- Repository
- The metadata describing all recorded states of a collection
of files. Each recorded state is represented by a changeset. A repository
is usually (but not always) found in the .hg subdirectory of a
working directory. Any recorded state can be recreated by
"updating" a working directory to a specific changeset.
- Repository head
- See 'Head, repository'.
- Revision
- A state of the repository at some point in time. Earlier
revisions can be updated to by using hg update. See also 'Revision
number'; See also 'Changeset'.
- Revision number
- This integer uniquely identifies a changeset in a specific
repository. It represents the order in which changesets were added to a
repository, starting with revision number 0. Note that the revision number
may be different in each clone of a repository. To identify changesets
uniquely between different clones, see 'Changeset id'.
- Revlog
- History storage mechanism used by Mercurial. It is a form
of delta encoding, with occasional full revision of data followed by delta
of each successive revision. It includes data and an index pointing to the
data.
- Rewriting history
- See 'History, rewriting'.
- Root
- A changeset that has only the null changeset as its parent.
Most repositories have only a single root changeset.
- Secret
- Changesets in the secret phase may not be shared via push,
pull, or clone. See hg help phases.
- Tag
- An alternative name given to a changeset. Tags can be used
in all places where Mercurial expects a changeset ID, e.g., with hg
update. The creation of a tag is stored in the history and will thus
automatically be shared with other using push and pull.
- Tip
- The changeset with the highest revision number. It is the
changeset most recently added in a repository.
- Tip, branch
- The head of a given branch with the highest revision
number. When a branch name is used as a revision identifier, it refers to
the branch tip. See also 'Branch, head'. Note that because revision
numbers may be different in different repository clones, the branch tip
may be different in different cloned repositories.
- Update
- (Noun) Another synonym of changeset.
Example: "I've pushed an update".
(Verb) This term is usually used to describe updating the state of the
working directory to that of a specific changeset. See hg help
update.
Example: "You should update".
- Working directory
- See 'Directory, working'.
- Working directory parent
- See 'Parent, working directory'.
SYNTAX FOR MERCURIAL IGNORE FILES¶
Synopsis¶
The Mercurial system uses a file called
.hgignore in the root directory
of a repository to control its behavior when it searches for files that it is
not currently tracking.
Description¶
The working directory of a Mercurial repository will often contain files that
should not be tracked by Mercurial. These include backup files created by
editors and build products created by compilers. These files can be ignored by
listing them in a
.hgignore file in the root of the working directory.
The
.hgignore file must be created manually. It is typically put under
version control, so that the settings will propagate to other repositories
with push and pull.
An untracked file is ignored if its path relative to the repository root
directory, or any prefix path of that path, is matched against any pattern in
.hgignore.
For example, say we have an untracked file,
file.c, at
a/b/file.c
inside our repository. Mercurial will ignore
file.c if any pattern in
.hgignore matches
a/b/file.c,
a/b or
a.
In addition, a Mercurial configuration file can reference a set of per-user or
global ignore files. See the
ignore configuration key on the
[ui] section of
hg help config for details of how to configure
these files.
To control Mercurial's handling of files that it manages, many commands support
the
-I and
-X options; see
hg help <command> and
hg help patterns for details.
Files that are already tracked are not affected by .hgignore, even if they
appear in .hgignore. An untracked file X can be explicitly added with
hg
add X, even if X would be excluded by a pattern in .hgignore.
Syntax¶
An ignore file is a plain text file consisting of a list of patterns, with one
pattern per line. Empty lines are skipped. The
# character is treated
as a comment character, and the
\ character is treated as an escape
character.
Mercurial supports several pattern syntaxes. The default syntax used is
Python/Perl-style regular expressions.
To change the syntax used, use a line of the following form:
syntax: NAME
where
NAME is one of the following:
- regexp
-
Regular expression, Python/Perl syntax.
- glob
-
Shell-style glob.
The chosen syntax stays in effect when parsing all patterns that follow, until
another syntax is selected.
Neither glob nor regexp patterns are rooted. A glob-syntax pattern of the form
*.c will match a file ending in
.c in any directory, and a
regexp pattern of the form
\.c$ will do the same. To root a regexp
pattern, start it with
^.
- Note
- Patterns specified in other than .hgignore are
always rooted. Please see hg help patterns for details.
Example¶
Here is an example ignore file.
# use glob syntax.
syntax: glob
*.elc
*.pyc
*~
# switch to regexp syntax.
syntax: regexp
^\.pc/
CONFIGURING HGWEB¶
Mercurial's internal web server, hgweb, can serve either a single repository, or
a tree of repositories. In the second case, repository paths and global
options can be defined using a dedicated configuration file common to
hg
serve,
hgweb.wsgi,
hgweb.cgi and
hgweb.fcgi.
This file uses the same syntax as other Mercurial configuration files but
recognizes only the following sections:
- •
- web
- •
- paths
- •
- collections
The
web options are thoroughly described in
hg help config.
The
paths section maps URL paths to paths of repositories in the
filesystem. hgweb will not expose the filesystem directly - only Mercurial
repositories can be published and only according to the configuration.
The left hand side is the path in the URL. Note that hgweb reserves subpaths
like
rev or
file, try using different names for nested
repositories to avoid confusing effects.
The right hand side is the path in the filesystem. If the specified path ends
with
* or
** the filesystem will be searched recursively for
repositories below that point. With
* it will not recurse into the
repositories it finds (except for
.hg/patches). With
** it will
also search inside repository working directories and possibly find
subrepositories.
In this example:
[paths]
/projects/a = /srv/tmprepos/a
/projects/b = c:/repos/b
/ = /srv/repos/*
/user/bob = /home/bob/repos/**
The
collections section is deprecated and has been superseded by
paths.
To merge files Mercurial uses merge tools.
A merge tool combines two different versions of a file into a merged file. Merge
tools are given the two files and the greatest common ancestor of the two file
versions, so they can determine the changes made on both branches.
Merge tools are used both for
hg resolve,
hg merge,
hg
update,
hg backout and in several extensions.
Usually, the merge tool tries to automatically reconcile the files by combining
all non-overlapping changes that occurred separately in the two different
evolutions of the same initial base file. Furthermore, some interactive merge
programs make it easier to manually resolve conflicting merges, either in a
graphical way, or by inserting some conflict markers. Mercurial does not
include any interactive merge programs but relies on external tools for that.
External merge tools and their properties are configured in the merge-tools
configuration section - see
hgrc(5) - but they can often just be named by
their executable.
A merge tool is generally usable if its executable can be found on the system
and if it can handle the merge. The executable is found if it is an absolute
or relative executable path or the name of an application in the executable
search path. The tool is assumed to be able to handle the merge if it can
handle symlinks if the file is a symlink, if it can handle binary files if the
file is binary, and if a GUI is available if the tool requires a GUI.
There are some internal merge tools which can be used. The internal merge tools
are:
- internal:dump
-
Creates three versions of the files to merge, containing the contents of
local, other and base. These files can then be used to perform a merge
manually. If the file to be merged is named a.txt, these files will
accordingly be named a.txt.local, a.txt.other and
a.txt.base and they will be placed in the same directory as
a.txt.
- internal:fail
-
Rather than attempting to merge files that were modified on both branches,
it marks them as unresolved. The resolve command must be used to resolve
these conflicts.
- internal:local
-
Uses the local version of files as the merged version.
- internal:merge
-
Uses the internal non-interactive simple merge algorithm for merging files.
It will fail if there are any conflicts and leave markers in the partially
merged file.
- internal:other
-
Uses the other version of files as the merged version.
- internal:prompt
-
Asks the user which of the local or the other version to keep as the merged
version.
- internal:tagmerge
-
Uses the internal tag merge algorithm (experimental).
Internal tools are always available and do not require a GUI but will by default
not handle symlinks or binary files.
Mercurial uses these rules when deciding which merge tool to use:
- 1.
- If a tool has been specified with the --tool option to
merge or resolve, it is used. If it is the name of a tool in the
merge-tools configuration, its configuration is used. Otherwise the
specified tool must be executable by the shell.
- 2.
- If the HGMERGE environment variable is present, its
value is used and must be executable by the shell.
- 3.
- If the filename of the file to be merged matches any of the
patterns in the merge-patterns configuration section, the first usable
merge tool corresponding to a matching pattern is used. Here, binary
capabilities of the merge tool are not considered.
- 4.
- If ui.merge is set it will be considered next. If the value
is not the name of a configured tool, the specified value is used and must
be executable by the shell. Otherwise the named tool is used if it is
usable.
- 5.
- If any usable merge tools are present in the merge-tools
configuration section, the one with the highest priority is used.
- 6.
- If a program named hgmerge can be found on the
system, it is used - but it will by default not be used for symlinks and
binary files.
- 7.
- If the file to be merged is not binary and is not a
symlink, then internal:merge is used.
- 8.
- The merge of the file fails and must be resolved before
commit.
- Note
- After selecting a merge program, Mercurial will by default
attempt to merge the files using a simple merge algorithm first. Only if
it doesn't succeed because of conflicting changes Mercurial will actually
execute the merge program. Whether to use the simple merge algorithm first
can be controlled by the premerge setting of the merge tool. Premerge is
enabled by default unless the file is binary or a symlink.
See the merge-tools and ui sections of
hgrc(5) for details on the configuration
of merge tools.
SPECIFYING MULTIPLE REVISIONS¶
When Mercurial accepts more than one revision, they may be specified
individually, or provided as a topologically continuous range, separated by
the ":" character.
The syntax of range notation is [BEGIN]:[END], where BEGIN and END are revision
identifiers. Both BEGIN and END are optional. If BEGIN is not specified, it
defaults to revision number 0. If END is not specified, it defaults to the
tip. The range ":" thus means "all revisions".
If BEGIN is greater than END, revisions are treated in reverse order.
A range acts as a closed interval. This means that a range of 3:5 gives 3, 4 and
5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
FILE NAME PATTERNS¶
Mercurial accepts several notations for identifying one or more files at a time.
By default, Mercurial treats filenames as shell-style extended glob patterns.
Alternate pattern notations must be specified explicitly.
- Note
- Patterns specified in .hgignore are not rooted.
Please see hg help hgignore for details.
To use a plain path name without any pattern matching, start it with
path:. These path names must completely match starting at the current
repository root.
To use an extended glob, start a name with
glob:. Globs are rooted at the
current directory; a glob such as
*.c will only match files in the
current directory ending with
.c.
The supported glob syntax extensions are
** to match any string across
path separators and
{a,b} to mean "a or b".
To use a Perl/Python regular expression, start a name with
re:. Regexp
pattern matching is anchored at the root of the repository.
To read name patterns from a file, use
listfile: or
listfile0:.
The latter expects null delimited patterns while the former expects line
feeds. Each string read from the file is itself treated as a file pattern.
All patterns, except for
glob: specified in command line (not for
-I or
-X options), can match also against directories: files
under matched directories are treated as matched.
Plain examples:
path:foo/bar a name bar in a directory named foo in the root
of the repository
path:path:name a file or directory named "path:name"
Glob examples:
glob:*.c any name ending in ".c" in the current directory
*.c any name ending in ".c" in the current directory
**.c any name ending in ".c" in any subdirectory of the
current directory including itself.
foo/*.c any name ending in ".c" in the directory foo
foo/**.c any name ending in ".c" in any subdirectory of foo
including itself.
Regexp examples:
re:.*\.c$ any name ending in ".c", anywhere in the repository
File examples:
listfile:list.txt read list from list.txt with one file pattern per line
listfile0:list.txt read list from list.txt with null byte delimiters
See also
hg help filesets.
WORKING WITH PHASES¶
What are phases?¶
Phases are a system for tracking which changesets have been or should be shared.
This helps prevent common mistakes when modifying history (for instance, with
the mq or rebase extensions).
Each changeset in a repository is in one of the following phases:
- •
- public : changeset is visible on a public server
- •
- draft : changeset is not yet published
- •
- secret : changeset should not be pushed, pulled, or
cloned
These phases are ordered (public < draft < secret) and no changeset can be
in a lower phase than its ancestors. For instance, if a changeset is public,
all its ancestors are also public. Lastly, changeset phases should only be
changed towards the public phase.
How are phases managed?¶
For the most part, phases should work transparently. By default, a changeset is
created in the draft phase and is moved into the public phase when it is
pushed to another repository.
Once changesets become public, extensions like mq and rebase will refuse to
operate on them to prevent creating duplicate changesets. Phases can also be
manually manipulated with the
hg phase command if needed. See
hg
help -v phase for examples.
Phases and servers¶
Normally, all servers are
publishing by default. This means:
- all draft changesets that are pulled or cloned appear in phase
public on the client
- all draft changesets that are pushed appear as public on both
client and server
- secret changesets are neither pushed, pulled, or cloned
- Note
- Pulling a draft changeset from a publishing server does not
mark it as public on the server side due to the read-only nature of
pull.
Sometimes it may be desirable to push and pull changesets in the draft phase to
share unfinished work. This can be done by setting a repository to disable
publishing in its configuration file:
[phases]
publish = False
See
hg help config for more information on configuration files.
- Note
- Servers running older versions of Mercurial are treated as
publishing.
- Note
- Changesets in secret phase are not exchanged with the
server. This applies to their content: file names, file contents, and
changeset metadata. For technical reasons, the identifier (e.g.
d825e4025e39) of the secret changeset may be communicated to the
server.
Examples¶
- •
- list changesets in draft or secret phase:
hg log -r "not public()"
- •
- change all secret changesets to draft:
hg phase --draft "secret()"
- •
- forcibly move the current changeset and descendants from
public to draft:
hg phase --force --draft .
- •
- show a list of changeset revision and phase:
hg log --template "{rev} {phase}\n"
- •
- resynchronize draft changesets relative to a remote
repository:
hg phase -fd "outgoing(URL)"
See
hg help phase for more information on manually manipulating phases.
SPECIFYING SINGLE REVISIONS¶
Mercurial supports several ways to specify individual revisions.
A plain integer is treated as a revision number. Negative integers are treated
as sequential offsets from the tip, with -1 denoting the tip, -2 denoting the
revision prior to the tip, and so forth.
A 40-digit hexadecimal string is treated as a unique revision identifier.
A hexadecimal string less than 40 characters long is treated as a unique
revision identifier and is referred to as a short-form identifier. A
short-form identifier is only valid if it is the prefix of exactly one
full-length identifier.
Any other string is treated as a bookmark, tag, or branch name. A bookmark is a
movable pointer to a revision. A tag is a permanent name associated with a
revision. A branch name denotes the tipmost open branch head of that branch -
or if they are all closed, the tipmost closed head of the branch. Bookmark,
tag, and branch names must not contain the ":" character.
The reserved name "tip" always identifies the most recent revision.
The reserved name "null" indicates the null revision. This is the
revision of an empty repository, and the parent of revision 0.
The reserved name "." indicates the working directory parent. If no
working directory is checked out, it is equivalent to null. If an uncommitted
merge is in progress, "." is the revision of the first parent.
SPECIFYING REVISION SETS¶
Mercurial supports a functional language for selecting a set of revisions.
The language supports a number of predicates which are joined by infix
operators. Parenthesis can be used for grouping.
Identifiers such as branch names may need quoting with single or double quotes
if they contain characters like
- or if they match one of the
predefined predicates.
Special characters can be used in quoted identifiers by escaping them, e.g.,
\n is interpreted as a newline. To prevent them from being interpreted,
strings can be prefixed with
r, e.g.
r'...'.
There is a single prefix operator:
- not x
-
Changesets not in x. Short form is ! x.
These are the supported infix operators:
- x::y
-
A DAG range, meaning all changesets that are descendants of x and ancestors
of y, including x and y themselves. If the first endpoint is left out,
this is equivalent to ancestors(y), if the second is left out it is
equivalent to descendants(x).
An alternative syntax is x..y.
- x:y
-
All changesets with revision numbers between x and y, both inclusive. Either
endpoint can be left out, they default to 0 and tip.
- x and y
-
The intersection of changesets in x and y. Short form is x &
y.
- x or y
-
The union of changesets in x and y. There are two alternative short forms:
x | y and x + y.
- x - y
-
Changesets in x but not in y.
- x^n
-
The nth parent of x, n == 0, 1, or 2. For n == 0, x; for n == 1, the first
parent of each changeset in x; for n == 2, the second parent of changeset
in x.
- x~n
-
The nth first ancestor of x; x~0 is x; x~3 is
x^^^.
There is a single postfix operator:
- x^
-
Equivalent to x^1, the first parent of each changeset in x.
The following predicates are supported:
- adds(pattern)
-
Changesets that add a file matching pattern.
The pattern without explicit kind like glob: is expected to be
relative to the current directory and match against a file or a
directory.
- all()
-
All changesets, the same as 0:tip.
- ancestor(*changeset)
-
A greatest common ancestor of the changesets.
Accepts 0 or more changesets. Will return empty list when passed no args.
Greatest common ancestor of a single changeset is that changeset.
- ancestors(set)
-
Changesets that are ancestors of a changeset in set.
- author(string)
-
Alias for user(string).
- bisect(string)
-
Changesets marked in the specified bisect status:
- •
- good, bad, skip: csets explicitly
marked as good/bad/skip
- •
- goods, bads : csets topologically
good/bad
- •
- range : csets taking part in the bisection
- •
- pruned : csets that are goods, bads or skipped
- •
- untested : csets whose fate is yet unknown
- •
- ignored : csets ignored due to DAG topology
- •
- current : the cset currently being bisected
- bookmark([name])
-
The named bookmark or all bookmarks.
If name starts with re:, the remainder of the name is treated
as a regular expression. To match a bookmark that actually starts with
re:, use the prefix literal:.
- branch(string or set)
-
All changesets belonging to the given branch or the branches of the given
changesets.
If string starts with re:, the remainder of the name is
treated as a regular expression. To match a branch that actually starts
with re:, use the prefix literal:.
- branchpoint()
-
Changesets with more than one child.
- bumped()
-
Mutable changesets marked as successors of public changesets.
Only non-public and non-obsolete changesets can be bumped.
- bundle()
-
Changesets in the bundle.
Bundle must be specified by the -R option.
- children(set)
-
Child changesets of changesets in set.
- closed()
-
Changeset is closed.
- contains(pattern)
-
The revision's manifest contains a file matching pattern (but might not
modify it). See hg help patterns for information about file
patterns.
The pattern without explicit kind like glob: is expected to be
relative to the current directory and match against a file exactly for
efficiency.
- converted([id])
-
Changesets converted from the given identifier in the old repository if
present, or all converted changesets if no identifier is specified.
- date(interval)
-
Changesets within the interval, see hg help dates.
- desc(string)
-
Search commit message for string. The match is case-insensitive.
- descendants(set)
-
Changesets which are descendants of changesets in set.
- destination([set])
-
Changesets that were created by a graft, transplant or rebase operation,
with the given revisions specified as the source. Omitting the optional
set is the same as passing all().
- divergent()
-
Final successors of changesets with an alternative set of final
successors.
- draft()
-
Changeset in draft phase.
- extinct()
-
Obsolete changesets with obsolete descendants only.
- extra(label, [value])
-
Changesets with the given label in the extra metadata, with the given
optional value.
If value starts with re:, the remainder of the value is
treated as a regular expression. To match a value that actually starts
with re:, use the prefix literal:.
- file(pattern)
-
Changesets affecting files matched by pattern.
For a faster but less accurate result, consider using filelog()
instead.
This predicate uses glob: as the default kind of pattern.
- filelog(pattern)
-
Changesets connected to the specified filelog.
For performance reasons, visits only revisions mentioned in the file-level
filelog, rather than filtering through all changesets (much faster, but
doesn't include deletes or duplicate changes). For a slower, more accurate
result, use file().
The pattern without explicit kind like glob: is expected to be
relative to the current directory and match against a file exactly for
efficiency.
- first(set, [n])
-
An alias for limit().
- follow([file])
-
An alias for ::. (ancestors of the working copy's first parent). If a
filename is specified, the history of the given file is followed,
including copies.
- grep(regex)
-
Like keyword(string) but accepts a regex. Use grep(r'...') to
ensure special escape characters are handled correctly. Unlike
keyword(string), the match is case-sensitive.
- head()
-
Changeset is a named branch head.
- heads(set)
-
Members of set with no children in set.
- hidden()
-
Hidden changesets.
- id(string)
-
Revision non-ambiguously specified by the given hex string prefix.
- keyword(string)
-
Search commit message, user name, and names of changed files for string. The
match is case-insensitive.
- last(set, [n])
-
Last n members of set, defaulting to 1.
- limit(set, [n])
-
First n members of set, defaulting to 1.
- matching(revision [, field])
-
Changesets in which a given set of fields match the set of fields in the
selected revision or set.
To match more than one field pass the list of fields to match separated by
spaces (e.g. author description).
Valid fields are most regular revision fields and some special fields.
Regular revision fields are description, author,
branch, date, files, phase, parents,
substate, user and diff. Note that author and
user are synonyms. diff refers to the contents of the
revision. Two revisions matching their diff will also match their
files.
Special fields are summary and metadata: summary
matches the first line of the description. metadata is equivalent
to matching description user date (i.e. it matches the main
metadata fields).
metadata is the default field which is used when no fields are
specified. You can match more than one field at a time.
- max(set)
-
Changeset with highest revision number in set.
- merge()
-
Changeset is a merge changeset.
- min(set)
-
Changeset with lowest revision number in set.
- modifies(pattern)
-
Changesets modifying files matched by pattern.
The pattern without explicit kind like glob: is expected to be
relative to the current directory and match against a file or a
directory.
- obsolete()
-
Mutable changeset with a newer version.
- only(set, [set])
-
Changesets that are ancestors of the first set that are not ancestors of any
other head in the repo. If a second set is specified, the result is
ancestors of the first set that are not ancestors of the second set (i.e.
::<set1> - ::<set2>).
- origin([set])
-
Changesets that were specified as a source for the grafts, transplants or
rebases that created the given revisions. Omitting the optional set is the
same as passing all(). If a changeset created by these operations is
itself specified as a source for one of these operations, only the source
changeset for the first operation is selected.
- outgoing([path])
-
Changesets not found in the specified destination repository, or the default
push location.
- p1([set])
-
First parent of changesets in set, or the working directory.
- p2([set])
-
Second parent of changesets in set, or the working directory.
- parents([set])
-
The set of all parents for all changesets in set, or the working
directory.
- present(set)
-
An empty set, if any revision in set isn't found; otherwise, all revisions
in set.
If any of specified revisions is not present in the local repository, the
query is normally aborted. But this predicate allows the query to continue
even in such cases.
- public()
-
Changeset in public phase.
- remote([id [,path]])
-
Local revision that corresponds to the given identifier in a remote
repository, if present. Here, the '.' identifier is a synonym for the
current local branch.
- removes(pattern)
-
Changesets which remove files matching pattern.
The pattern without explicit kind like glob: is expected to be
relative to the current directory and match against a file or a
directory.
- rev(number)
-
Revision with the given numeric identifier.
- reverse(set)
-
Reverse order of set.
- roots(set)
-
Changesets in set with no parent changeset in set.
- secret()
-
Changeset in secret phase.
- sort(set[, [-]key...])
-
Sort set by keys. The default sort order is ascending, specify a key as
-key to sort in descending order.
The keys can be:
- •
- rev for the revision number,
- •
- branch for the branch name,
- •
- desc for the commit message (description),
- •
- user for user name (author can be used as an
alias),
- •
- date for the commit date
- tag([name])
-
The specified tag by name, or all tagged revisions if no name is given.
If name starts with re:, the remainder of the name is treated
as a regular expression. To match a tag that actually starts with
re:, use the prefix literal:.
- unstable()
-
Non-obsolete changesets with obsolete ancestors.
- user(string)
-
User name contains string. The match is case-insensitive.
If string starts with re:, the remainder of the string is
treated as a regular expression. To match a user that actually contains
re:, use the prefix literal:.
New predicates (known as "aliases") can be defined, using any
combination of existing predicates or other aliases. An alias definition looks
like:
<alias> = <definition>
in the
revsetalias section of a Mercurial configuration file. Arguments
of the form
$1,
$2, etc. are substituted from the alias into the
definition.
For example,
[revsetalias]
h = heads()
d($1) = sort($1, date)
rs($1, $2) = reverse(sort($1, $2))
defines three aliases,
h,
d, and
rs.
rs(0:tip,
author) is exactly equivalent to
reverse(sort(0:tip, author)).
Command line equivalents for
hg log:
-f -> ::.
-d x -> date(x)
-k x -> keyword(x)
-m -> merge()
-u x -> user(x)
-b x -> branch(x)
-P x -> !::x
-l x -> limit(expr, x)
Some sample queries:
- •
- Changesets on the default branch:
hg log -r "branch(default)"
- •
- Changesets on the default branch since tag 1.5 (excluding
merges):
hg log -r "branch(default) and 1.5:: and not merge()"
- •
- Open branch heads:
hg log -r "head() and not closed()"
- •
- Changesets between tags 1.3 and 1.5 mentioning
"bug" that affect hgext/*:
hg log -r "1.3::1.5 and keyword(bug) and file('hgext/*')"
- •
- Changesets committed in May 2008, sorted by user:
hg log -r "sort(date('May 2008'), user)"
- •
- Changesets mentioning "bug" or "issue"
that are not in a tagged release:
hg log -r "(keyword(bug) or keyword(issue)) and not ancestors(tag())"
SUBREPOSITORIES¶
Subrepositories let you nest external repositories or projects into a parent
Mercurial repository, and make commands operate on them as a group.
Mercurial currently supports Mercurial, Git, and Subversion subrepositories.
Subrepositories are made of three components:
- 1.
- Nested repository checkouts. They can appear anywhere in
the parent working directory.
- 2.
- Nested repository references. They are defined in
.hgsub, which should be placed in the root of working directory,
and tell where the subrepository checkouts come from. Mercurial
subrepositories are referenced like:
path/to/nested = https://example.com/nested/repo/path
Git and Subversion subrepos are also supported:
path/to/nested = [git]git://example.com/nested/repo/path
path/to/nested = [svn]https://example.com/nested/trunk/path
where path/to/nested is the checkout location relatively to the
parent Mercurial root, and https://example.com/nested/repo/path is
the source repository path. The source can also reference a filesystem
path.
Note that .hgsub does not exist by default in Mercurial repositories,
you have to create and add it to the parent repository before using
subrepositories.
- 3.
- Nested repository states. They are defined in
.hgsubstate, which is placed in the root of working directory, and
capture whatever information is required to restore the subrepositories to
the state they were committed in a parent repository changeset. Mercurial
automatically record the nested repositories states when committing in the
parent repository.
- Note
- The .hgsubstate file should not be edited
manually.
Adding a Subrepository¶
If
.hgsub does not exist, create it and add it to the parent repository.
Clone or checkout the external projects where you want it to live in the
parent repository. Edit
.hgsub and add the subrepository entry as
described above. At this point, the subrepository is tracked and the next
commit will record its state in
.hgsubstate and bind it to the
committed changeset.
Synchronizing a Subrepository¶
Subrepos do not automatically track the latest changeset of their sources.
Instead, they are updated to the changeset that corresponds with the changeset
checked out in the top-level changeset. This is so developers always get a
consistent set of compatible code and libraries when they update.
Thus, updating subrepos is a manual process. Simply check out target subrepo at
the desired revision, test in the top-level repo, then commit in the parent
repository to record the new combination.
Deleting a Subrepository¶
To remove a subrepository from the parent repository, delete its reference from
.hgsub, then remove its files.
Interaction with Mercurial Commands¶
- add
- add does not recurse in subrepos unless -S/--subrepos is
specified. However, if you specify the full path of a file in a subrepo,
it will be added even without -S/--subrepos specified. Git and Subversion
subrepositories are currently silently ignored.
- archive
- archive does not recurse in subrepositories unless
-S/--subrepos is specified.
- cat
- cat currently only handles exact file matches in subrepos.
Git and Subversion subrepositories are currently ignored.
- commit
- commit creates a consistent snapshot of the state of the
entire project and its subrepositories. If any subrepositories have been
modified, Mercurial will abort. Mercurial can be made to instead commit
all modified subrepositories by specifying -S/--subrepos, or setting
"ui.commitsubrepos=True" in a configuration file (see hg help
config). After there are no longer any modified subrepositories, it
records their state and finally commits it in the parent repository.
- diff
- diff does not recurse in subrepos unless -S/--subrepos is
specified. Changes are displayed as usual, on the subrepositories
elements. Git and Subversion subrepositories are currently silently
ignored.
- forget
- forget currently only handles exact file matches in
subrepos. Git and Subversion subrepositories are currently silently
ignored.
- incoming
- incoming does not recurse in subrepos unless -S/--subrepos
is specified. Git and Subversion subrepositories are currently silently
ignored.
- outgoing
- outgoing does not recurse in subrepos unless -S/--subrepos
is specified. Git and Subversion subrepositories are currently silently
ignored.
- pull
- pull is not recursive since it is not clear what to pull
prior to running hg update. Listing and retrieving all
subrepositories changes referenced by the parent repository pulled
changesets is expensive at best, impossible in the Subversion case.
- push
- Mercurial will automatically push all subrepositories first
when the parent repository is being pushed. This ensures new subrepository
changes are available when referenced by top-level repositories. Push is a
no-op for Subversion subrepositories.
- status
- status does not recurse into subrepositories unless
-S/--subrepos is specified. Subrepository changes are displayed as regular
Mercurial changes on the subrepository elements. Subversion
subrepositories are currently silently ignored.
- update
- update restores the subrepos in the state they were
originally committed in target changeset. If the recorded changeset is not
available in the current subrepository, Mercurial will pull it in first
before updating. This means that updating can require network access when
using subrepositories.
Remapping Subrepositories Sources¶
A subrepository source location may change during a project life, invalidating
references stored in the parent repository history. To fix this, rewriting
rules can be defined in parent repository
hgrc file or in Mercurial
configuration. See the
[subpaths] section in
hgrc(5) for more details.
TEMPLATE USAGE¶
Mercurial allows you to customize output of commands through templates. You can
either pass in a template or select an existing template-style from the
command line, via the --template option.
You can customize output for any "log-like" command: log, outgoing,
incoming, tip, parents, and heads.
Some built-in styles are packaged with Mercurial. These can be listed with
hg
log --template list. Example usage:
$ hg log -r1.0::1.1 --template changelog
A template is a piece of text, with markup to invoke variable expansion:
$ hg log -r1 --template "{node}\n"
b56ce7b07c52de7d5fd79fb89701ea538af65746
Strings in curly braces are called keywords. The availability of keywords
depends on the exact context of the templater. These keywords are usually
available for templating a log-like command:
- author
- String. The unmodified author of the changeset.
- bisect
- String. The changeset bisection status.
- bookmarks
- List of strings. Any bookmarks associated with the
changeset.
- branch
- String. The name of the branch on which the changeset was
committed.
- children
- List of strings. The children of the changeset.
- currentbookmark
- String. The active bookmark, if it is associated with the
changeset
- date
- Date information. The date when the changeset was
committed.
- desc
- String. The text of the changeset description.
- diffstat
- String. Statistics of changes with the following format:
"modified files: +added/-removed lines"
- extras
- List of dicts with key, value entries of the 'extras' field
of this changeset.
- file_adds
- List of strings. Files added by this changeset.
- file_copies
- List of strings. Files copied in this changeset with their
sources.
- file_copies_switch
- List of strings. Like "file_copies" but displayed
only if the --copied switch is set.
- file_dels
- List of strings. Files removed by this changeset.
- file_mods
- List of strings. Files modified by this changeset.
- files
- List of strings. All files modified, added, or removed by
this changeset.
- latesttag
- String. Most recent global tag in the ancestors of this
changeset.
- latesttagdistance
- Integer. Longest path to the latest tag.
- node
- String. The changeset identification hash, as a 40
hexadecimal digit string.
- p1node
- String. The identification hash of the changeset's first
parent, as a 40 digit hexadecimal string. If the changeset has no parents,
all digits are 0.
- p1rev
- Integer. The repository-local revision number of the
changeset's first parent, or -1 if the changeset has no parents.
- p2node
- String. The identification hash of the changeset's second
parent, as a 40 digit hexadecimal string. If the changeset has no second
parent, all digits are 0.
- p2rev
- Integer. The repository-local revision number of the
changeset's second parent, or -1 if the changeset has no second
parent.
- parents
- List of strings. The parents of the changeset in
"rev:node" format. If the changeset has only one
"natural" parent (the predecessor revision) nothing is
shown.
- phase
- String. The changeset phase name.
- phaseidx
- Integer. The changeset phase index.
- rev
- Integer. The repository-local changeset revision
number.
- subrepos
- List of strings. Updated subrepositories in the
changeset.
- tags
- List of strings. Any tags associated with the
changeset.
The "date" keyword does not produce human-readable output. If you want
to use a date in your output, you can use a filter to process it. Filters are
functions which return a string based on the input variable. Be sure to use
the stringify filter first when you're applying a string-input filter to a
list-like input variable. You can also use a chain of filters to get the
desired output:
$ hg tip --template "{date|isodate}\n"
2008-08-21 18:22 +0000
List of filters:
- addbreaks
- Any text. Add an XHTML "<br />" tag before
the end of every line except the last.
- age
- Date. Returns a human-readable date/time difference between
the given date/time and the current date/time.
- basename
- Any text. Treats the text as a path, and returns the last
component of the path after splitting by the path separator (ignoring
trailing separators). For example, "foo/bar/baz" becomes
"baz" and "foo/bar//" becomes "bar".
- date
- Date. Returns a date in a Unix date format, including the
timezone: "Mon Sep 04 15:13:13 2006 0700".

email address. Example: User <user@example.com> becomes
user@example.com.
- emailuser
- Any text. Returns the user portion of an email

13:00 +0200".
- isodatesec
- Date. Returns the date in ISO 8601 format, including

headers: "Tue, 18 Aug 2009 13:00:13 +0200".
- short
- Changeset hash. Returns the short form of a changeset hash,
i.e. a 12 hexadecimal digit string.
- shortbisect
- Any text. Treats text as a bisection status, and
returns a single-character representing the status (G: good, B: bad, S:

email address.
Note that a filter is nothing more than a function call, i.e.
expr|filter
is equivalent to
filter(expr).
In addition to filters, there are some basic built-in functions:
- •
- date(date[, fmt])
- •
- fill(text[, width])
- •
- get(dict, key)
- •
- if(expr, then[, else])
- •
- ifcontains(expr, expr, then[, else])
- •
- ifeq(expr, expr, then[, else])
- •
- join(list, sep)
- •
- label(label, expr)
- •
- pad(text, width[, fillchar, right])
- •
- revset(query[, formatargs])
- •
- rstdoc(text, style)
- •
- shortest(node)
- •
- startswith(string, text)
- •
- strip(text[, chars])
- •
- sub(pat, repl, expr)
- •
- word(number, text[, separator])
Also, for any expression that returns a list, there is a list operator:
Some sample command line templates:
- •
- Format lists, e.g. files:
$ hg log -r 0 --template "files:\n{files % ' {file}\n'}"
- •
- Join the list of files with a ", ":
$ hg log -r 0 --template "files: {join(files, ', ')}\n"
- •
- Modify each line of a commit description:
$ hg log --template "{splitlines(desc) % '**** {line}\n'}"
- •
- Format date:
$ hg log -r 0 --template "{date(date, '%Y')}\n"
- •
- Output the description set to a fill-width of 30:
$ hg log -r 0 --template "{fill(desc, '30')}"
- •
- Use a conditional to test for the default branch:
$ hg log -r 0 --template "{ifeq(branch, 'default', 'on the main branch',
'on branch {branch}')}\n"
- •
- Append a newline if not empty:
$ hg tip --template "{if(author, '{author}\n')}"
- •
- Label the output for use with the color extension:
$ hg log -r 0 --template "{label('changeset.{phase}', node|short)}\n"
- •
- Invert the firstline filter, i.e. everything but the first
line:
$ hg log -r 0 --template "{sub(r'^.*\n?\n?', '', desc)}\n"
- •
- Display the contents of the 'extra' field, one per line:
$ hg log -r 0 --template "{join(extras, '\n')}\n"
- •
- Mark the current bookmark with '*':
$ hg log --template "{bookmarks % '{bookmark}{ifeq(bookmark, current, \"*\")} '}\n"
- •
- Mark the working copy parent with '@':
$ hg log --template "{ifcontains(rev, revset('.'), '@')}\n"
- •
- Show only commit descriptions that start with
"template":
$ hg log --template "{startswith(\"template\", firstline(desc))}\n"
- •
- Print the first word of each line of a commit message:
$ hg log --template "{word(\"0\", desc)}\n"
URL PATHS¶
Valid URLs are of the form:
local/filesystem/path[#revision]
file://local/filesystem/path[#revision]
http://[user[:pass]@]host[:port]/[path][#revision]
https://[user[:pass]@]host[:port]/[path][#revision]
ssh://[user@]host[:port]/[path][#revision]
Paths in the local filesystem can either point to Mercurial repositories or to
bundle files (as created by
hg bundle or
hg incoming --bundle).
See also
hg help paths.
An optional identifier after # indicates a particular branch, tag, or changeset
to use from the remote repository. See also
hg help revisions.
Some features, such as pushing to
http:// and
https:// URLs are only possible if
the feature is explicitly enabled on the remote Mercurial server.
Note that the security of HTTPS URLs depends on proper configuration of
web.cacerts.
Some notes about using SSH with Mercurial:
- •
- SSH requires an accessible shell account on the destination
machine and a copy of hg in the remote path or specified with as
remotecmd.
- •
- path is relative to the remote user's home directory by
default. Use an extra slash at the start of a path to specify an absolute
path:
ssh://example.com//tmp/repository
- •
- Mercurial doesn't use its own compression via SSH; the
right thing to do is to configure it in your ~/.ssh/config, e.g.:
Host *.mylocalnetwork.example.com
Compression no
Host *
Compression yes
Alternatively specify "ssh -C" as your ssh command in your
configuration file or with the --ssh command line option.
These URLs can all be stored in your configuration file with path aliases under
the [paths] section like so:
[paths]
alias1 = URL1
alias2 = URL2
...
You can then use the alias for any command that uses a URL (for example
hg
pull alias1 will be treated as
hg pull URL1).
Two path aliases are special because they are used as defaults when you do not
provide the URL to a command:
- default:
- When you create a repository with hg clone, the clone
command saves the location of the source repository as the new
repository's 'default' path. This is then used when you omit path from
push- and pull-like commands (including incoming and outgoing).
- default-push:
- The push command will look for a path named 'default-push',
and prefer it over 'default' if both are defined.
EXTENSIONS¶
This section contains help for extensions that are distributed together with
Mercurial. Help for other extensions is available in the help system.
acl¶
hooks for controlling repository access
This hook makes it possible to allow or deny write access to given branches and
paths of a repository when receiving incoming changesets via pretxnchangegroup
and pretxncommit.
The authorization is matched based on the local user name on the system where
the hook runs, and not the committer of the original changeset (since the
latter is merely informative).
The acl hook is best used along with a restricted shell like hgsh, preventing
authenticating users from doing anything other than pushing or pulling. The
hook is not safe to use if users have interactive shell access, as they can
then disable the hook. Nor is it safe if remote users share an account,
because then there is no way to distinguish them.
The order in which access checks are performed is:
- 1.
- Deny list for branches (section
acl.deny.branches)
- 2.
- Allow list for branches (section
acl.allow.branches)
- 3.
- Deny list for paths (section acl.deny)
- 4.
- Allow list for paths (section acl.allow)
The allow and deny sections take key-value pairs.
Branch-based Access Control¶
Use the
acl.deny.branches and
acl.allow.branches sections to have
branch-based access control. Keys in these sections can be either:
- •
- a branch name, or
- •
- an asterisk, to match any branch;
The corresponding values can be either:
- •
- a comma-separated list containing users and groups, or
- •
- an asterisk, to match anyone;
You can add the "!" prefix to a user or group name to invert the sense
of the match.
Path-based Access Control¶
Use the
acl.deny and
acl.allow sections to have path-based access
control. Keys in these sections accept a subtree pattern (with a glob syntax
by default). The corresponding values follow the same syntax as the other
sections above.
Groups¶
Group names must be prefixed with an
@ symbol. Specifying a group name
has the same effect as specifying all the users in that group.
You can define group members in the
acl.groups section. If a group name
is not defined there, and Mercurial is running under a Unix-like system, the
list of users will be taken from the OS. Otherwise, an exception will be
raised.
Example Configuration¶
[hooks]
# Use this if you want to check access restrictions at commit time
pretxncommit.acl = python:hgext.acl.hook
# Use this if you want to check access restrictions for pull, push,
# bundle and serve.
pretxnchangegroup.acl = python:hgext.acl.hook
[acl]
# Allow or deny access for incoming changes only if their source is
# listed here, let them pass otherwise. Source is "serve" for all
# remote access (http or ssh), "push", "pull" or "bundle" when the
# related commands are run locally.
# Default: serve
sources = serve
[acl.deny.branches]
# Everyone is denied to the frozen branch:
frozen-branch = *
# A bad user is denied on all branches:
* = bad-user
[acl.allow.branches]
# A few users are allowed on branch-a:
branch-a = user-1, user-2, user-3
# Only one user is allowed on branch-b:
branch-b = user-1
# The super user is allowed on any branch:
* = super-user
# Everyone is allowed on branch-for-tests:
branch-for-tests = *
[acl.deny]
# This list is checked first. If a match is found, acl.allow is not
# checked. All users are granted access if acl.deny is not present.
# Format for both lists: glob pattern = user, ..., @group, ...
# To match everyone, use an asterisk for the user:
# my/glob/pattern = *
# user6 will not have write access to any file:
** = user6
# Group "hg-denied" will not have write access to any file:
** = @hg-denied
# Nobody will be able to change "DONT-TOUCH-THIS.txt", despite
# everyone being able to change all other files. See below.
src/main/resources/DONT-TOUCH-THIS.txt = *
[acl.allow]
# if acl.allow is not present, all users are allowed by default
# empty acl.allow = no users allowed
# User "doc_writer" has write access to any file under the "docs"
# folder:
docs/** = doc_writer
# User "jack" and group "designers" have write access to any file
# under the "images" folder:
images/** = jack, @designers
# Everyone (except for "user6" and "@hg-denied" - see acl.deny above)
# will have write access to any file under the "resources" folder
# (except for 1 file. See acl.deny):
src/main/resources/** = *
.hgtags = release_engineer
Examples using the ! prefix¶
Suppose there's a branch that only a given user (or group) should be able to
push to, and you don't want to restrict access to any other branch that may be
created.
The "!" prefix allows you to prevent anyone except a given user or
group to push changesets in a given branch or path.
In the examples below, we will: 1) Deny access to branch "ring" to
anyone but user "gollum" 2) Deny access to branch "lake"
to anyone but members of the group "hobbit" 3) Deny access to a file
to anyone but user "gollum"
[acl.allow.branches]
# Empty
[acl.deny.branches]
# 1) only 'gollum' can commit to branch 'ring';
# 'gollum' and anyone else can still commit to any other branch.
ring = !gollum
# 2) only members of the group 'hobbit' can commit to branch 'lake';
# 'hobbit' members and anyone else can still commit to any other branch.
lake = !@hobbit
# You can also deny access based on file paths:
[acl.allow]
# Empty
[acl.deny]
# 3) only 'gollum' can change the file below;
# 'gollum' and anyone else can still change any other file.
/misty/mountains/cave/ring = !gollum
blackbox¶
log repository events to a blackbox for debugging
Logs event information to .hg/blackbox.log to help debug and diagnose problems.
The events that get logged can be configured via the blackbox.track config
key. Examples:
[blackbox]
track = *
[blackbox]
track = command, commandfinish, commandexception, exthook, pythonhook
[blackbox]
track = incoming
[blackbox]
# limit the size of a log file
maxsize = 1.5 MB
# rotate up to N log files when the current one gets too big
maxfiles = 3
Commands¶
blackbox¶
view the recent repository events:
hg blackbox [OPTION]...
view the recent repository events
Options:
- -l,--limit <VALUE>
- the number of events to show (default: 10)
bugzilla¶
hooks for integrating with the Bugzilla bug tracker
This hook extension adds comments on bugs in Bugzilla when changesets that refer
to bugs by Bugzilla ID are seen. The comment is formatted using the Mercurial
template mechanism.
The bug references can optionally include an update for Bugzilla of the hours
spent working on the bug. Bugs can also be marked fixed.
Three basic modes of access to Bugzilla are provided:
- 1.
- Access via the Bugzilla XMLRPC interface. Requires Bugzilla
3.4 or later.
- 2.
- Check data via the Bugzilla XMLRPC interface and submit bug
change via email to Bugzilla email interface. Requires Bugzilla 3.4 or
later.
- 3.
- Writing directly to the Bugzilla database. Only Bugzilla
installations using MySQL are supported. Requires Python MySQLdb.
Writing directly to the database is susceptible to schema changes, and relies on
a Bugzilla contrib script to send out bug change notification emails. This
script runs as the user running Mercurial, must be run on the host with the
Bugzilla install, and requires permission to read Bugzilla configuration
details and the necessary MySQL user and password to have full access rights
to the Bugzilla database. For these reasons this access mode is now considered
deprecated, and will not be updated for new Bugzilla versions going forward.
Only adding comments is supported in this access mode.
Access via XMLRPC needs a Bugzilla username and password to be specified in the
configuration. Comments are added under that username. Since the configuration
must be readable by all Mercurial users, it is recommended that the rights of
that user are restricted in Bugzilla to the minimum necessary to add comments.
Marking bugs fixed requires Bugzilla 4.0 and later.
Access via XMLRPC/email uses XMLRPC to query Bugzilla, but sends email to the
Bugzilla email interface to submit comments to bugs. The From: address in the
email is set to the email address of the Mercurial user, so the comment
appears to come from the Mercurial user. In the event that the Mercurial user
email is not recognized by Bugzilla as a Bugzilla user, the email associated
with the Bugzilla username used to log into Bugzilla is used instead as the
source of the comment. Marking bugs fixed works on all supported Bugzilla
versions.
Configuration items common to all access modes:
- bugzilla.version
- The access type to use. Values recognized are:
- xmlrpc
-
Bugzilla XMLRPC interface.
- xmlrpc+email
-
Bugzilla XMLRPC and email interfaces.
- 3.0
-
MySQL access, Bugzilla 3.0 and later.
- 2.18
-
MySQL access, Bugzilla 2.18 and up to but not including 3.0.
- 2.16
-
MySQL access, Bugzilla 2.16 and up to but not including 2.18.
- bugzilla.regexp
- Regular expression to match bug IDs for update in changeset
commit message. It must contain one "()" named group
<ids> containing the bug IDs separated by non-digit
characters. It may also contain a named group <hours> with a
floating-point number giving the hours worked on the bug. If no named
groups are present, the first "()" group is assumed to contain
the bug IDs, and work time is not updated. The default expression matches
Bug 1234, Bug no. 1234, Bug number 1234, Bugs
1234,5678, Bug 1234 and 5678 and variations thereof, followed
by an hours number prefixed by h or hours, e.g. hours
1.5. Matching is case insensitive.
- bugzilla.fixregexp
- Regular expression to match bug IDs for marking fixed in
changeset commit message. This must contain a "()" named group
<ids>` containing the bug IDs separated by non-digit
characters. It may also contain a named group ``<hours>
with a floating-point number giving the hours worked on the bug. If no
named groups are present, the first "()" group is assumed to
contain the bug IDs, and work time is not updated. The default expression
matches Fixes 1234, Fixes bug 1234, Fixes bugs
1234,5678, Fixes 1234 and 5678 and variations thereof, followed
by an hours number prefixed by h or hours, e.g. hours
1.5. Matching is case insensitive.
- bugzilla.fixstatus
- The status to set a bug to when marking fixed. Default
RESOLVED.
- bugzilla.fixresolution
- The resolution to set a bug to when marking fixed. Default
FIXED.
- bugzilla.style
- The style file to use when formatting comments.
- bugzilla.template
- Template to use when formatting comments. Overrides style
if specified. In addition to the usual Mercurial keywords, the extension
specifies:
- {bug}
-
The Bugzilla bug ID.
- {root}
-
The full pathname of the Mercurial repository.
- {webroot}
-
Stripped pathname of the Mercurial repository.
- {hgweb}
-
Base URL for browsing Mercurial repositories.
Default
changeset {node|short} in repo {root} refers to bug
{bug}.\ndetails:\n\t{desc|tabindent}
- bugzilla.strip
- The number of path separator characters to strip from the
front of the Mercurial repository path ( {root} in templates) to
produce {webroot}. For example, a repository with {root}
/var/local/my-project with a strip of 2 gives a value for
{webroot} of my-project. Default 0.
- web.baseurl
- Base URL for browsing Mercurial repositories. Referenced
from templates as {hgweb}.
Configuration items common to XMLRPC+email and MySQL access modes:
- bugzilla.usermap
- Path of file containing Mercurial committer email to
Bugzilla user email mappings. If specified, the file should contain one
mapping per line:
committer = Bugzilla user
See also the [usermap] section.
The
[usermap] section is used to specify mappings of Mercurial committer
email to Bugzilla user email. See also
bugzilla.usermap. Contains
entries of the form
committer = Bugzilla user.
XMLRPC access mode configuration:
- bugzilla.bzurl
- The base URL for the Bugzilla installation. Default
http://localhost/bugzilla.
- bugzilla.user
- The username to use to log into Bugzilla via XMLRPC.
Default bugs.
- bugzilla.password
- The password for Bugzilla login.
XMLRPC+email access mode uses the XMLRPC access mode configuration items, and
also:
- bugzilla.bzemail
- The Bugzilla email address.
In addition, the Mercurial email settings must be configured. See the
documentation in
hgrc(5), sections
[email] and
[smtp].
MySQL access mode configuration:
- bugzilla.host
- Hostname of the MySQL server holding the Bugzilla database.
Default localhost.
- bugzilla.db
- Name of the Bugzilla database in MySQL. Default
bugs.
- bugzilla.user
- Username to use to access MySQL server. Default
bugs.
- bugzilla.password
- Password to use to access MySQL server.
- bugzilla.timeout
- Database connection timeout (seconds). Default 5.
- bugzilla.bzuser
- Fallback Bugzilla user name to record comments with, if
changeset committer cannot be found as a Bugzilla user.
- bugzilla.bzdir
- Bugzilla install directory. Used by default notify. Default
/var/www/html/bugzilla.
- bugzilla.notify
- The command to run to get Bugzilla to send bug change
notification emails. Substitutes from a map with 3 keys, bzdir,
id (bug id) and user (committer bugzilla email). Default
depends on version; from 2.18 it is "cd %(bzdir)s && perl -T
contrib/sendbugmail.pl %(id)s %(user)s".

children¶
command to display child changesets (DEPRECATED)
This extension is deprecated. You should use
hg log -r
"children(REV)" instead.
Commands¶
children¶
show the children of the given or working directory revision:
hg children [-r REV] [FILE]
Print the children of the working directory's revisions. If a revision is given
via -r/--rev, the children of that revision will be printed. If a file
argument is given, revision in which the file was last changed (after the
working directory revision or the argument to --rev if given) is printed.
Options:
- -r,--rev <REV>
- show children of the specified revision
- --style <STYLE>
- display using template map file (DEPRECATED)
- -T,--template <TEMPLATE>
- display with template
churn¶
command to display statistics about repository history
Commands¶
churn¶
histogram of changes to the repository:
hg churn [-d DATE] [-r REV] [--aliases FILE] [FILE]
This command will display a histogram representing the number of changed lines
or revisions, grouped according to the given template. The default template
will group changes by author. The --dateformat option may be used to group the
results by date instead.
Statistics are based on the number of changed lines, or alternatively the number
of matching revisions if the --changesets option is specified.
Examples:
# display count of changed lines for every committer
hg churn -t "{author|email}"
# display daily activity graph
hg churn -f "%H" -s -c
# display activity of developers by month
hg churn -f "%Y-%m" -s -c
# display count of lines changed in every year
hg churn -f "%Y" -s
It is possible to map alternate email addresses to a main address by providing a
file using the following format:
<alias email> = <actual email>
Such a file may be specified with the --aliases option, otherwise a .hgchurn
file will be looked for in the working directory root. Aliases will be split
from the rightmost "=".
Options:
- -r,--rev <REV[+]>
- count rate for the specified revision or range
- -d,--date <DATE>
- count rate for revisions matching date spec
- -t,--template <TEMPLATE>
- template to group changesets (default: {author|email})
- -f,--dateformat <FORMAT>
- strftime-compatible format for grouping by date
- -c, --changesets
- count rate by number of changesets
- -s, --sort
- sort by key (default: sort by count)
- --diffstat
- display added/removed lines separately
- --aliases <FILE>
- file with email aliases
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
color¶
colorize output from some commands
This extension modifies the status and resolve commands to add color to their
output to reflect file status, the qseries command to add color to reflect
patch status (applied, unapplied, missing), and to diff-related commands to
highlight additions, removals, diff headers, and trailing whitespace.
Other effects in addition to color, like bold and underlined text, are also
available. By default, the terminfo database is used to find the terminal
codes used to change color and effect. If terminfo is not available, then
effects are rendered with the ECMA-48 SGR control function (aka ANSI escape
codes).
Default effects may be overridden from your configuration file:
[color]
status.modified = blue bold underline red_background
status.added = green bold
status.removed = red bold blue_background
status.deleted = cyan bold underline
status.unknown = magenta bold underline
status.ignored = black bold
# 'none' turns off all effects
status.clean = none
status.copied = none
qseries.applied = blue bold underline
qseries.unapplied = black bold
qseries.missing = red bold
diff.diffline = bold
diff.extended = cyan bold
diff.file_a = red bold
diff.file_b = green bold
diff.hunk = magenta
diff.deleted = red
diff.inserted = green
diff.changed = white
diff.trailingwhitespace = bold red_background
resolve.unresolved = red bold
resolve.resolved = green bold
bookmarks.current = green
branches.active = none
branches.closed = black bold
branches.current = green
branches.inactive = none
tags.normal = green
tags.local = black bold
rebase.rebased = blue
rebase.remaining = red bold
shelve.age = cyan
shelve.newest = green bold
shelve.name = blue bold
histedit.remaining = red bold
The available effects in terminfo mode are 'blink', 'bold', 'dim', 'inverse',
'invisible', 'italic', 'standout', and 'underline'; in ECMA-48 mode, the
options are 'bold', 'inverse', 'italic', and 'underline'. How each is rendered
depends on the terminal emulator. Some may not be available for a given
terminal type, and will be silently ignored.
Note that on some systems, terminfo mode may cause problems when using color
with the pager extension and less -R. less with the -R option will only
display ECMA-48 color codes, and terminfo mode may sometimes emit codes that
less doesn't understand. You can work around this by either using ansi mode
(or auto mode), or by using less -r (which will pass through all terminal
control codes, not just color control codes).
Because there are only eight standard colors, this module allows you to define
color names for other color slots which might be available for your terminal
type, assuming terminfo mode. For instance:
color.brightblue = 12
color.pink = 207
color.orange = 202
to set 'brightblue' to color slot 12 (useful for 16 color terminals that have
brighter colors defined in the upper eight) and, 'pink' and 'orange' to colors
in 256-color xterm's default color cube. These defined colors may then be used
as any of the pre-defined eight, including appending '_background' to set the
background to that color.
By default, the color extension will use ANSI mode (or win32 mode on Windows) if
it detects a terminal. To override auto mode (to enable terminfo mode, for
example), set the following configuration option:
[color]
mode = terminfo
Any value other than 'ansi', 'win32', 'terminfo', or 'auto' will disable color.

source).
If no destination directory name is specified, it defaults to the basename of
the source with
-hg appended. If the destination repository doesn't
exist, it will be created.
By default, all sources except Mercurial will use --branchsort. Mercurial uses
--sourcesort to preserve original revision numbers order. Sort modes have the
following effects:
- --branchsort
- convert from parent to child revision when possible, which
means branches are usually converted one after the other. It generates
more compact repositories.
- --datesort
- sort revisions by date. Converted repositories have
good-looking changelogs but are often an order of magnitude larger than
the same ones generated by --branchsort.
- --sourcesort
- try to preserve source revisions order, only supported by
Mercurial sources.
- --closesort
- try to move closed revisions as close as possible to parent
branches, only supported by Mercurial sources.
If
REVMAP isn't given, it will be put in a default location (
<dest>/.hg/shamap by default). The
REVMAP is a simple text
file that maps each source commit ID to the destination ID for that revision,
like so:
<source ID> <destination ID>
If the file doesn't exist, it's automatically created. It's updated on each
commit copied, so
hg convert can be interrupted and can be run
repeatedly to copy new commits.
The authormap is a simple text file that maps each source commit author to a
destination commit author. It is handy for source SCMs that use unix logins to
identify authors (e.g.: CVS). One line per author mapping and the line format
is:
source author = destination author
Empty lines and lines starting with a
# are ignored.
The filemap is a file that allows filtering and remapping of files and
directories. Each line can contain one of the following directives:
include path/to/file-or-dir
exclude path/to/file-or-dir
rename path/to/source path/to/destination
Comment lines start with
#. A specified path matches if it equals the
full relative name of a file or one of its parent directories. The
include or
exclude directive with the longest matching path
applies, so line order does not matter.
The
include directive causes a file, or all files under a directory, to
be included in the destination repository. The default if there are no
include statements is to include everything. If there are any
include statements, nothing else is included. The
exclude
directive causes files or directories to be omitted. The
rename
directive renames a file or directory if it is converted. To rename from a
subdirectory into the root of the repository, use
. as the path to
rename to.
The splicemap is a file that allows insertion of synthetic history, letting you
specify the parents of a revision. This is useful if you want to e.g. give a
Subversion merge two parents, or graft two disconnected series of history
together. Each entry contains a key, followed by a space, followed by one or
two comma-separated values:
key parent1, parent2
The key is the revision ID in the source revision control system whose parents
should be modified (same format as a key in .hg/shamap). The values are the
revision IDs (in either the source or destination revision control system)
that should be used as the new parents for that node. For example, if you have
merged "release-1.0" into "trunk", then you should specify
the revision on "trunk" as the first parent and the one on the
"release-1.0" branch as the second.
The branchmap is a file that allows you to rename a branch when it is being
brought in from whatever external repository. When used in conjunction with a
splicemap, it allows for a powerful combination to help fix even the most
badly mismanaged repositories and turn them into nicely structured Mercurial
repositories. The branchmap contains lines of the form:
original_branch_name new_branch_name
where "original_branch_name" is the name of the branch in the source
repository, and "new_branch_name" is the name of the branch is the
destination repository. No whitespace is allowed in the branch names. This can
be used to (for instance) move code in one repository from "default"
to a named branch.
Mercurial Source¶
The Mercurial source recognizes the following configuration options, which you
can set on the command line with
--config:
- convert.hg.ignoreerrors
- ignore integrity errors when reading. Use it to fix
Mercurial repositories with missing revlogs, by converting from and to
Mercurial. Default is False.
- convert.hg.saverev
- store original revision ID in changeset (forces target IDs
to change). It takes a boolean argument and defaults to False.
- convert.hg.revs
- revset specifying the source revisions to convert.
CVS Source¶
CVS source will use a sandbox (i.e. a checked-out copy) from CVS to indicate the
starting point of what will be converted. Direct access to the repository
files is not needed, unless of course the repository is
:local:. The
conversion uses the top level directory in the sandbox to find the CVS
repository, and then uses CVS rlog commands to find files to convert. This
means that unless a filemap is given, all files under the starting directory
will be converted, and that any directory reorganization in the CVS sandbox is
ignored.
The following options can be used with
--config:
- convert.cvsps.cache
- Set to False to disable remote log caching, for testing and
debugging purposes. Default is True.
- convert.cvsps.fuzz
- Specify the maximum time (in seconds) that is allowed
between commits with identical user and log message in a single changeset.
When very large files were checked in as part of a changeset then the
default may not be long enough. The default is 60.
- convert.cvsps.mergeto
- Specify a regular expression to which commit log messages
are matched. If a match occurs, then the conversion process will insert a
dummy revision merging the branch on which this log message occurs to the
branch indicated in the regex. Default is {{mergetobranch
([-\w]+)}}
- convert.cvsps.mergefrom
- Specify a regular expression to which commit log messages
are matched. If a match occurs, then the conversion process will add the
most recent revision on the branch indicated in the regex as the second
parent of the changeset. Default is {{mergefrombranch
([-\w]+)}}
- convert.localtimezone
- use local time (as determined by the TZ environment
variable) for changeset date/times. The default is False (use UTC).
- hooks.cvslog
- Specify a Python function to be called at the end of
gathering the CVS log. The function is passed a list with the log entries,
and can modify the entries in-place, or add or delete them.
- hooks.cvschangesets
- Specify a Python function to be called after the changesets
are calculated from the CVS log. The function is passed a list with the
changeset entries, and can modify the changesets in-place, or add or
delete them.
An additional "debugcvsps" Mercurial command allows the builtin
changeset merging code to be run without doing a conversion. Its parameters
and output are similar to that of cvsps 2.1. Please see the command help for
more details.
Subversion Source¶
Subversion source detects classical trunk/branches/tags layouts. By default, the
supplied
svn://repo/path/ source URL is converted as a single branch.
If
svn://repo/path/trunk exists it replaces the default branch. If
svn://repo/path/branches exists, its subdirectories are listed as
possible branches. If
svn://repo/path/tags exists, it is looked for
tags referencing converted branches. Default
trunk,
branches and
tags values can be overridden with following options. Set them to paths
relative to the source URL, or leave them blank to disable auto detection.
The following options can be set with
--config:
- convert.svn.branches
- specify the directory containing branches. The default is
branches.
- convert.svn.tags
- specify the directory containing tags. The default is
tags.
- convert.svn.trunk
- specify the name of the trunk branch. The default is
trunk.
- convert.localtimezone
- use local time (as determined by the TZ environment
variable) for changeset date/times. The default is False (use UTC).
Source history can be retrieved starting at a specific revision, instead of
being integrally converted. Only single branch conversions are supported.
- convert.svn.startrev
- specify start Subversion revision number. The default is
0.
Perforce Source¶
The Perforce (P4) importer can be given a p4 depot path or a client
specification as source. It will convert all files in the source to a flat
Mercurial repository, ignoring labels, branches and integrations. Note that
when a depot path is given you then usually should specify a target directory,
because otherwise the target may be named
...-hg.
It is possible to limit the amount of source history to be converted by
specifying an initial Perforce revision:
- convert.p4.startrev
- specify initial Perforce revision (a Perforce changelist
number).
Mercurial Destination¶
The following options are supported:
- convert.hg.clonebranches
- dispatch source branches in separate clones. The default is
False.
- convert.hg.tagsbranch
- branch name for tag revisions, defaults to
default.
- convert.hg.usebranchnames
- preserve branch names. The default is True.
Options:
- --authors <FILE>
- username mapping filename (DEPRECATED, use --authormap
instead)
- -s,--source-type <TYPE>
- source repository type
- -d,--dest-type <TYPE>
- destination repository type
- -r,--rev <REV>
- import up to source revision REV
- -A,--authormap <FILE>
- remap usernames using this file
- --filemap <FILE>
- remap file names using contents of file
- --splicemap <FILE>
- splice synthesized history into place
- --branchmap <FILE>
- change branch names while converting
- --branchsort
- try to sort changesets by branches
- --datesort
- try to sort changesets by date
- --sourcesort
- preserve source changesets order
- --closesort
- try to reorder closed revisions
eol¶
automatically manage newlines in repository files
This extension allows you to manage the type of line endings (CRLF or LF) that
are used in the repository and in the local working directory. That way you
can get CRLF line endings on Windows and LF on Unix/Mac, thereby letting
everybody use their OS native line endings.
The extension reads its configuration from a versioned
.hgeol
configuration file found in the root of the working copy. The
.hgeol
file use the same syntax as all other Mercurial configuration files. It uses
two sections,
[patterns] and
[repository].
The
[patterns] section specifies how line endings should be converted
between the working copy and the repository. The format is specified by a file
pattern. The first match is used, so put more specific patterns first. The
available line endings are
LF,
CRLF, and
BIN.
Files with the declared format of
CRLF or
LF are always checked
out and stored in the repository in that format and files declared to be
binary (
BIN) are left unchanged. Additionally,
native is an
alias for checking out in the platform's default line ending:
LF on
Unix (including Mac OS X) and
CRLF on Windows. Note that
BIN (do
nothing to line endings) is Mercurial's default behaviour; it is only needed
if you need to override a later, more general pattern.
The optional
[repository] section specifies the line endings to use for
files stored in the repository. It has a single setting,
native, which
determines the storage line endings for files declared as
native in the
[patterns] section. It can be set to
LF or
CRLF. The
default is
LF. For example, this means that on Windows, files
configured as
native (
CRLF by default) will be converted to
LF when stored in the repository. Files declared as
LF,
CRLF, or
BIN in the
[patterns] section are always stored
as-is in the repository.
Example versioned
.hgeol file:
[patterns]
**.py = native
**.vcproj = CRLF
**.txt = native
Makefile = LF
**.jpg = BIN
[repository]
native = LF
- Note
- The rules will first apply when files are touched in the
working copy, e.g. by updating to null and back to tip to touch all
files.
The extension uses an optional
[eol] section read from both the normal
Mercurial configuration files and the
.hgeol file, with the latter
overriding the former. You can use that section to control the overall
behavior. There are three settings:
- •
- eol.native (default os.linesep) can be set to
LF or CRLF to override the default interpretation of
native for checkout. This can be used with hg archive on
Unix, say, to generate an archive where files have line endings for
Windows.
- •
- eol.only-consistent (default True) can be set to
False to make the extension convert files with inconsistent EOLs.
Inconsistent means that there is both CRLF and LF present in
the file. Such files are normally not touched under the assumption that
they have mixed EOLs on purpose.
- •
- eol.fix-trailing-newline (default False) can be set
to True to ensure that converted files end with a EOL character (either
\n or \r\n as per the configured patterns).
The extension provides
cleverencode: and
cleverdecode: filters
like the deprecated win32text extension does. This means that you can disable
win32text and enable eol and your filters will still work. You only need to
these filters until you have prepared a
.hgeol file.
The
win32text.forbid* hooks provided by the win32text extension have been
unified into a single hook named
eol.checkheadshook. The hook will
lookup the expected line endings from the
.hgeol file, which means you
must migrate to a
.hgeol file first before using the hook.
eol.checkheadshook only checks heads, intermediate invalid revisions
will be pushed. To forbid them completely, use the
eol.checkallhook
hook. These hooks are best used as
pretxnchangegroup hooks.
See
hg help patterns for more information about the glob patterns used.
extdiff¶
command to allow external programs to compare revisions
The extdiff Mercurial extension allows you to use external programs to compare
revisions, or revision with working directory. The external diff programs are
called with a configurable set of options and two non-option arguments: paths
to directories containing snapshots of files to compare.
The extdiff extension also allows you to configure new diff commands, so you do
not need to type
hg extdiff -p kdiff3 always.
[extdiff]
# add new command that runs GNU diff(1) in 'context diff' mode
cdiff = gdiff -Nprc5
## or the old way:
#cmd.cdiff = gdiff
#opts.cdiff = -Nprc5
# add new command called vdiff, runs kdiff3
vdiff = kdiff3
# add new command called meld, runs meld (no need to name twice)
meld =
# add new command called vimdiff, runs gvimdiff with DirDiff plugin
# (see http://www.vim.org/scripts/script.php?script_id=102) Non
# English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in
# your .vimrc
vimdiff = gvim -f "+next" \
"+execute 'DirDiff' fnameescape(argv(0)) fnameescape(argv(1))"
Tool arguments can include variables that are expanded at runtime:
$parent1, $plabel1 - filename, descriptive label of first parent
$child, $clabel - filename, descriptive label of child revision
$parent2, $plabel2 - filename, descriptive label of second parent
$root - repository root
$parent is an alias for $parent1.
The extdiff extension will look in your [diff-tools] and [merge-tools] sections
for diff tool arguments, when none are specified in [extdiff].
[extdiff]
kdiff3 =
[diff-tools]
kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child
You can use -I/-X and list of file or directory names like normal
hg diff
command. The extdiff extension makes snapshots of only needed files, so
running the external diff program will actually be pretty fast (at least
faster than having to compare the entire tree).
Commands¶
extdiff¶
use external program to diff repository (or selected files):
hg extdiff [OPT]... [FILE]...
Show differences between revisions for the specified files, using an external
program. The default program used is diff, with default options
"-Npru".
To select a different program, use the -p/--program option. The program will be
passed the names of two directories to compare. To pass additional options to
the program, use -o/--option. These will be passed before the names of the
directories to compare.
When two revision arguments are given, then changes are shown between those
revisions. If only one revision is specified then that revision is compared to
the working directory, and, when no revisions are specified, the working
directory files are compared to its parent.
Options:
- -p,--program <CMD>
- comparison program to run
- -o,--option <OPT[+]>
- pass option to comparison program
- -r,--rev <REV[+]>
- revision
- -c,--change <REV>
- change made by revision
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
factotum¶
http authentication with factotum
This extension allows the factotum(4) facility on Plan 9 from Bell Labs
platforms to provide authentication information for HTTP access. Configuration
entries specified in the auth section as well as authentication information
provided in the repository URL are fully supported. If no prefix is specified,
a value of "*" will be assumed.
By default, keys are specified as:
proto=pass service=hg prefix=<prefix> user=<username> !password=<password>
If the factotum extension is unable to read the required key, one will be
requested interactively.
A configuration section is available to customize runtime behavior. By default,
these entries are:
[factotum]
executable = /bin/auth/factotum
mountpoint = /mnt/factotum
service = hg
The executable entry defines the full path to the factotum binary. The
mountpoint entry defines the path to the factotum file service. Lastly, the
service entry controls the service name used when reading keys.
fetch¶
pull, update and merge in one command (DEPRECATED)
Commands¶
fetch¶
pull changes from a remote repository, merge new changes if needed.:
hg fetch [SOURCE]
This finds all changes from the repository at the specified path or URL and adds
them to the local repository.
If the pulled changes add a new branch head, the head is automatically merged,
and the result of the merge is committed. Otherwise, the working directory is
updated to include the new changes.
When a merge is needed, the working directory is first updated to the newly
pulled changes. Local changes are then merged into the pulled changes. To
switch the merge order, use --switch-parent.
See
hg help dates for a list of formats valid for -d/--date.
Returns 0 on success.
Options:
- -r,--rev <REV[+]>
- a specific revision you would like to pull
- -e, --edit
- invoke editor on commit messages
- --force-editor
- edit commit message (DEPRECATED)
- --switch-parent
- switch parents when merging
- -m,--message <TEXT>
- use text as commit message
- -l,--logfile <FILE>
- read commit message from file
- -d,--date <DATE>
- record the specified date as commit date
- -u,--user <USER>
- record the specified user as committer
- -e,--ssh <CMD>
- specify ssh command to use
- --remotecmd <CMD>
- specify hg command to run on the remote side
- --insecure
- do not verify server certificate (ignoring web.cacerts
config)
[+] marked option can be specified multiple times

Options:
- -l, --local
- make the signature local
- -f, --force
- sign even if the sigfile is modified

The functionality of this extension has been include in core Mercurial since
version 2.3.
This extension adds a --graph option to the incoming, outgoing and log commands.
When this options is given, an ASCII representation of the revision graph is
also shown.
Commands¶
glog¶

[+] marked option can be specified multiple times
hgcia¶
hooks for integrating with the CIA.vc notification service
This is meant to be run as a changegroup or incoming hook. To configure it, set
the following options in your hgrc:
[cia]
# your registered CIA user name
user = foo
# the name of the project in CIA
project = foo
# the module (subproject) (optional)
#module = foo
# Append a diffstat to the log message (optional)
#diffstat = False
# Template to use for log messages (optional)
#template = {desc}\n{baseurl}{webroot}/rev/{node}-- {diffstat}
# Style to use (optional)
#style = foo
# The URL of the CIA notification service (optional)
# You can use mailto: URLs to send by email, e.g.
# mailto:cia@cia.vc
# Make sure to set email.from if you do this.
#url = http://cia.vc/
# print message instead of sending it (optional)
#test = False
# number of slashes to strip for url paths
#strip = 0
[hooks]
# one of these:
changegroup.cia = python:hgcia.hook
#incoming.cia = python:hgcia.hook
[web]
# If you want hyperlinks (optional)
baseurl = http://server/path/to/repo
hgk¶
browse the repository in a graphical way
The hgk extension allows browsing the history of a repository in a graphical
way. It requires Tcl/Tk version 8.4 or later. (Tcl/Tk is not distributed with
Mercurial.)
hgk consists of two parts: a Tcl script that does the displaying and querying of
information, and an extension to Mercurial named hgk.py, which provides hooks
for hgk to get information. hgk can be found in the contrib directory, and the
extension is shipped in the hgext repository, and needs to be enabled.
The
hg view command will launch the hgk Tcl script. For this command to
work, hgk must be in your search path. Alternately, you can specify the path
to hgk in your configuration file:
[hgk]
path=/location/of/hgk
hgk can make use of the extdiff extension to visualize revisions. Assuming you
had already configured extdiff vdiff command, just add:
[hgk]
vdiff=vdiff
Revisions context menu will now display additional entries to fire vdiff on
hovered and selected revisions.
Commands¶
view¶
start interactive history viewer:
hg view [-l LIMIT] [REVRANGE]
start interactive history viewer
Options:
- -l,--limit <NUM>
- limit number of changes displayed
highlight¶
syntax highlighting for hgweb (requires Pygments)
It depends on the Pygments syntax highlighting library:
http://pygments.org/
There is a single configuration option:
[web]
pygments_style = <style>
The default is 'colorful'.
histedit¶
interactive history editing
With this extension installed, Mercurial gains one new command: histedit. Usage
is as follows, assuming the following history:
@ 3[tip] 7c2fd3b9020c 2009-04-27 18:04 -0500 durin42
| Add delta
|
o 2 030b686bedc4 2009-04-27 18:04 -0500 durin42
| Add gamma
|
o 1 c561b4e977df 2009-04-27 18:04 -0500 durin42
| Add beta
|
o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42
Add alpha
If you were to run
hg histedit c561b4e977df, you would see the following
file open in your editor:
pick c561b4e977df Add beta
pick 030b686bedc4 Add gamma
pick 7c2fd3b9020c Add delta
# Edit history between c561b4e977df and 7c2fd3b9020c
#
# Commits are listed from least to most recent
#
# Commands:
# p, pick = use commit
# e, edit = use commit, but stop for amending
# f, fold = use commit, but combine it with the one above
# d, drop = remove commit from history
# m, mess = edit message without changing commit content
#
In this file, lines beginning with
# are ignored. You must specify a rule
for each revision in your history. For example, if you had meant to add gamma
before beta, and then wanted to add delta in the same revision as beta, you
would reorganize the file to look like this:
pick 030b686bedc4 Add gamma
pick c561b4e977df Add beta
fold 7c2fd3b9020c Add delta
# Edit history between c561b4e977df and 7c2fd3b9020c
#
# Commits are listed from least to most recent
#
# Commands:
# p, pick = use commit
# e, edit = use commit, but stop for amending
# f, fold = use commit, but combine it with the one above
# d, drop = remove commit from history
# m, mess = edit message without changing commit content
#
At which point you close the editor and
histedit starts working. When you
specify a
fold operation,
histedit will open an editor when it
folds those revisions together, offering you a chance to clean up the commit
message:
Add beta
***
Add delta
Edit the commit message to your liking, then close the editor. For this example,
let's assume that the commit message was changed to
Add beta and delta.
After histedit has run and had a chance to remove any old or temporary
revisions it needed, the history looks like this:
@ 2[tip] 989b4d060121 2009-04-27 18:04 -0500 durin42
| Add beta and delta.
|
o 1 081603921c3f 2009-04-27 18:04 -0500 durin42
| Add gamma
|
o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42
Add alpha
Note that
histedit does
not remove any revisions (even its own
temporary ones) until after it has completed all the editing operations, so it
will probably perform several strip operations when it's done. For the above
example, it had to run strip twice. Strip can be slow depending on a variety
of factors, so you might need to be a little patient. You can choose to keep
the original revisions by passing the
--keep flag.
The
edit operation will drop you back to a command prompt, allowing you
to edit files freely, or even use
hg record to commit some changes as a
separate commit. When you're done, any remaining uncommitted changes will be
committed as well. When done, run
hg histedit --continue to
finish this step. You'll be prompted for a new commit message, but the default
commit message will be the original message for the
edit ed revision.
The
message operation will give you a chance to revise a commit message
without changing the contents. It's a shortcut for doing
edit
immediately followed by
hg histedit --continue`.
If
histedit encounters a conflict when moving a revision (while handling
pick or
fold), it'll stop in a similar manner to
edit
with the difference that it won't prompt you for a commit message when done.
If you decide at this point that you don't like how much work it will be to
rearrange history, or that you made a mistake, you can use
hg histedit
--abort to abandon the new changes you have made and return to the state
before you attempted to edit your history.
If we clone the histedit-ed example repository above and add four more changes,
such that we have the following history:
@ 6[tip] 038383181893 2009-04-27 18:04 -0500 stefan
| Add theta
|
o 5 140988835471 2009-04-27 18:04 -0500 stefan
| Add eta
|
o 4 122930637314 2009-04-27 18:04 -0500 stefan
| Add zeta

| Add gamma
|
o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42
Add alpha
If you run
hg histedit --outgoing on the clone then it is the same as
running
hg histedit 836302820282. If you need plan to push to a
repository that Mercurial does not detect to be related to the source repo,
you can add a
--force option.
Commands¶
histedit¶
interactively edit changeset history:
hg histedit ANCESTOR | --outgoing [URL]
This command edits changesets between ANCESTOR and the parent of the working
directory.
With --outgoing, this edits changesets not found in the destination repository.
If URL of the destination is omitted, the 'default-push' (or 'default') path
will be used.
For safety, this command is aborted, also if there are ambiguous outgoing
revisions which may confuse users: for example, there are multiple branches
containing outgoing revisions.
Use "min(outgoing() and ::.)" or similar revset specification instead
of --outgoing to specify edit target revision exactly in such ambiguous
situation. See
hg help revsets for detail about selecting revisions.
Returns 0 on success, 1 if user intervention is required (not only for
intentional "edit" command, but also for resolving unexpected
conflicts).
Options:
- --commands <VALUE>
- Read history edits from the specified file.
- -c, --continue
- continue an edit already in progress
- -k, --keep
- don't strip old nodes after edit is complete
- --abort
- abort an edit in progress
- -o, --outgoing
- changesets not found in destination
- -f, --force
- force outgoing even for unrelated repositories
- -r,--rev <VALUE[+]>
- first revision to be edited
[+] marked option can be specified multiple times
keyword¶
expand keywords in tracked files
This extension expands RCS/CVS-like or self-customized $Keywords$ in tracked
text files selected by your configuration.
Keywords are only expanded in local repositories and not stored in the change
history. The mechanism can be regarded as a convenience for the current user
or for archive distribution.
Keywords expand to the changeset data pertaining to the latest change relative
to the working directory parent of each file.
Configuration is done in the [keyword], [keywordset] and [keywordmaps] sections
of hgrc files.
Example:
[keyword]
# expand keywords in every python file except those matching "x*"
**.py =
x* = ignore
[keywordset]
# prefer svn- over cvs-like default keywordmaps
svn = True
- Note
- The more specific you are in your filename patterns the
less you lose speed in huge repositories.
For [keywordmaps] template mapping and expansion demonstration and control run
hg kwdemo. See
hg help templates for a list of available
templates and filters.
Three additional date template filters are provided:
- utcdate
-
"2006/09/18 15:13:13"
- svnutcdate
-
"2006-09-18 15:13:13Z"
- svnisodate
-
"2006-09-18 08:13:13 -700 (Mon, 18 Sep 2006)"
The default template mappings (view with
hg kwdemo -d) can be replaced
with customized keywords and templates. Again, run
hg kwdemo to control
the results of your configuration changes.
Before changing/disabling active keywords, you must run
hg kwshrink to
avoid storing expanded keywords in the change history.
To force expansion after enabling it, or a configuration change, run
hg
kwexpand.
Expansions spanning more than one line and incremental expansions, like CVS'
$Log$, are not supported. A keyword template map "Log = {desc}"
expands to the first line of the changeset description.
Commands¶
kwdemo¶
print [keywordmaps] configuration and an expansion example:
hg kwdemo [-d] [-f RCFILE] [TEMPLATEMAP]...
Show current, custom, or default keyword template maps and their expansions.
Extend the current configuration by specifying maps as arguments and using
-f/--rcfile to source an external hgrc file.
Use -d/--default to disable current configuration.
See
hg help templates for information on templates and filters.
Options:
- -d, --default
- show default keyword template maps
- -f,--rcfile <FILE>
- read maps from rcfile
kwexpand¶
expand keywords in the working directory:
hg kwexpand [OPTION]... [FILE]...
Run after (re)enabling keyword expansion.
kwexpand refuses to run if given files contain local changes.
Options:
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
kwfiles¶
show files configured for keyword expansion:
hg kwfiles [OPTION]... [FILE]...
List which files in the working directory are matched by the [keyword]
configuration patterns.
Useful to prevent inadvertent keyword expansion and to speed up execution by
including only files that are actual candidates for expansion.
See
hg help keyword on how to construct patterns both for inclusion and
exclusion of files.
With -A/--all and -v/--verbose the codes used to show the status of files are:
K = keyword expansion candidate
k = keyword expansion candidate (not tracked)
I = ignored
i = ignored (not tracked)
Options:
- -A, --all
- show keyword status flags of all files
- -i, --ignore
- show files excluded from expansion
- -u, --unknown
- only show unknown (not tracked) files
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
kwshrink¶
revert expanded keywords in the working directory:
hg kwshrink [OPTION]... [FILE]...
Must be run before changing/disabling active keywords.
kwshrink refuses to run if given files contain local changes.
Options:
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
largefiles¶
track large binary files
Large binary files tend to be not very compressible, not very diffable, and not
at all mergeable. Such files are not handled efficiently by Mercurial's
storage format (revlog), which is based on compressed binary deltas; storing
large binary files as regular Mercurial files wastes bandwidth and disk space
and increases Mercurial's memory usage. The largefiles extension addresses
these problems by adding a centralized client-server layer on top of
Mercurial: largefiles live in a
central store out on the network
somewhere, and you only fetch the revisions that you need when you need them.
largefiles works by maintaining a "standin file" in .hglf/ for each
largefile. The standins are small (41 bytes: an SHA-1 hash plus newline) and
are tracked by Mercurial. Largefile revisions are identified by the SHA-1 hash
of their contents, which is written to the standin. largefiles uses that
revision ID to get/put largefile revisions from/to the central store. This
saves both disk space and bandwidth, since you don't need to retrieve all
historical revisions of large files when you clone or pull.
To start a new repository or add new large binary files, just add --large to
your
hg add command. For example:
$ dd if=/dev/urandom of=randomdata count=2000
$ hg add --large randomdata
$ hg commit -m 'add randomdata as a largefile'
When you push a changeset that adds/modifies largefiles to a remote repository,
its largefile revisions will be uploaded along with it. Note that the remote
Mercurial must also have the largefiles extension enabled for this to work.
When you pull a changeset that affects largefiles from a remote repository, the
largefiles for the changeset will by default not be pulled down. However, when
you update to such a revision, any largefiles needed by that revision are
downloaded and cached (if they have never been downloaded before). One way to
pull largefiles when pulling is thus to use --update, which will update your
working copy to the latest pulled revision (and thereby downloading any new
largefiles).
If you want to pull largefiles you don't need for update yet, then you can use
pull with the
--lfrev option or the
hg lfpull command.
If you know you are pulling from a non-default location and want to download all
the largefiles that correspond to the new changesets at the same time, then
you can pull with
--lfrev "pulled()".
If you just want to ensure that you will have the largefiles needed to merge or
rebase with new heads that you are pulling, then you can pull with
--lfrev
"head(pulled())" flag to pre-emptively download any largefiles
that are new in the heads you are pulling.
Keep in mind that network access may now be required to update to changesets
that you have not previously updated to. The nature of the largefiles
extension means that updating is no longer guaranteed to be a local-only
operation.
If you already have large files tracked by Mercurial without the largefiles
extension, you will need to convert your repository in order to benefit from
largefiles. This is done with the
hg lfconvert command:
$ hg lfconvert --size 10 oldrepo newrepo
In repositories that already have largefiles in them, any new file over 10MB
will automatically be added as a largefile. To change this threshold, set
largefiles.minsize in your Mercurial config file to the minimum size in
megabytes to track as a largefile, or use the --lfsize option to the add
command (also in megabytes):
[largefiles]
minsize = 2
$ hg add --lfsize 2
The
largefiles.patterns config option allows you to specify a list of
filename patterns (see
hg help patterns) that should always be tracked
as largefiles:
[largefiles]
patterns =
*.jpg
re:.*\.(png|bmp)$
library.zip
content/audio/*
Files that match one of these patterns will be added as largefiles regardless of
their size.
The
largefiles.minsize and
largefiles.patterns config options will
be ignored for any repositories not already containing a largefile. To add the
first largefile to a repository, you must explicitly do so with the --large
flag passed to the
hg add command.
Commands¶
lfconvert¶
convert a normal repository to a largefiles repository:
hg lfconvert SOURCE DEST [FILE ...]
Convert repository SOURCE to a new repository DEST, identical to SOURCE except
that certain files will be converted as largefiles: specifically, any file
that matches any PATTERN
or whose size is above the minimum size
threshold is converted as a largefile. The size used to determine whether or
not to track a file as a largefile is the size of the first version of the
file. The minimum size can be specified either with --size or in configuration
as
largefiles.size.
After running this command you will need to make sure that largefiles is enabled
anywhere you intend to push the new repository.
Use --to-normal to convert largefiles back to normal files; after this, the DEST
repository can be used without largefiles at all.
Options:
- -s,--size <SIZE>
- minimum size (MB) for files to be converted as
largefiles
- --to-normal
- convert from a largefiles repo to a normal repo
lfpull¶
pull largefiles for the specified revisions from the specified source:
hg lfpull -r REV... [-e CMD] [--remotecmd CMD] [SOURCE]
Pull largefiles that are referenced from local changesets but missing locally,
pulling from a remote repository to the local cache.
If SOURCE is omitted, the 'default' path will be used. See
hg help urls
for more information.
Some examples:
- •
- pull largefiles for all branch heads:
hg lfpull -r "head() and not closed()"
- •
- pull largefiles on the default branch:
hg lfpull -r "branch(default)"
Options:
- -r,--rev <VALUE[+]>
- pull largefiles for these revisions
- -e,--ssh <CMD>
- specify ssh command to use
- --remotecmd <CMD>
- specify hg command to run on the remote side
- --insecure
- do not verify server certificate (ignoring web.cacerts
config)
[+] marked option can be specified multiple times
manage a stack of patches
This extension lets you work with a stack of patches in a Mercurial repository.
It manages two stacks of patches - all known patches, and applied patches
(subset of known patches).
Known patches are represented as patch files in the .hg/patches directory.
Applied patches are both patch files and changesets.
Common tasks (use
hg help command for more details):
create new patch qnew
import existing patch qimport
print patch series qseries
print applied patches qapplied
add known patch to applied stack qpush
remove patch from applied stack qpop
refresh contents of top applied patch qrefresh
By default, mq will automatically use git patches when required to avoid losing
file mode changes, copy records, binary files or empty files creations or
deletions. This behaviour can be configured with:
[mq]
git = auto/keep/yes/no
If set to 'keep', mq will obey the [diff] section configuration while preserving
existing git patches upon qrefresh. If set to 'yes' or 'no', mq will override
the [diff] section and always generate git or regular patches, possibly losing
data in the second case.
It may be desirable for mq changesets to be kept in the secret phase (see
hg
help phases), which can be enabled with the following setting:
[mq]
secret = True
You will by default be managing a patch queue named "patches". You can
create other, independent patch queues with the
hg qqueue command.
If the working directory contains uncommitted files, qpush, qpop and qgoto abort
immediately. If -f/--force is used, the changes are discarded. Setting:
[mq]
keepchanges = True
make them behave as if --keep-changes were passed, and non-conflicting local
changes will be tolerated and preserved. If incompatible options such as
-f/--force or --exact are passed, this setting is ignored.
This extension used to provide a strip command. This command now lives in the
strip extension.
Commands¶
qapplied¶
print the patches already applied:
hg qapplied [-1] [-s] [PATCH]
Returns 0 on success.
Options:
- -1, --last
- show only the preceding applied patch
- -s, --summary
- print first line of patch header
qclone¶
clone main and patch repository at same time:
hg qclone [OPTION]... SOURCE [DEST]
If source is local, destination will have no patches applied. If source is
remote, this command can not check if patches are applied in source, so cannot
guarantee that patches are not applied in destination. If you clone remote
repository, be sure before that it has no patches applied.
Source patch repository is looked for in <src>/.hg/patches by default. Use
-p <url> to change.
The patch directory must be a nested Mercurial repository, as would be created
by
hg init --mq.
Return 0 on success.
Options:
- --pull
- use pull protocol to copy metadata
- -U, --noupdate
- do not update the new working directories
- --uncompressed
- use uncompressed transfer (fast over LAN)
- -p,--patches <REPO>
- location of source patch repository
- -e,--ssh <CMD>
- specify ssh command to use
- --remotecmd <CMD>
- specify hg command to run on the remote side
- --insecure
- do not verify server certificate (ignoring web.cacerts
config)

hg qcommit [OPTION]... [FILE]...
This command is deprecated; use
hg commit --mq instead.
Options:
- -A, --addremove
- mark new/missing files as added/removed before
committing
- --close-branch
- mark a branch as closed, hiding it from the branch
list
- --amend
- amend the parent of the working dir
- -s, --secret
- use the secret phase for committing
- -e, --edit
- invoke editor on commit messages
- -I,--include <PATTERN[+]>

- -u,--user <USER>
- record the specified user as committer
- -S, --subrepos
- recurse into subrepositories
[+] marked option can be specified multiple times
qdelete¶
remove patches from queue:
hg qdelete [-k] [PATCH]...
The patches must not be applied, and at least one patch is required. Exact patch
identifiers must be given. With -k/--keep, the patch files are preserved in
the patch directory.
To stop managing a patch and move it into permanent history, use the
hg
qfinish command.
Options:
- -k, --keep
- keep patch file
- -r,--rev <REV[+]>
- stop managing a revision (DEPRECATED)
[+] marked option can be specified multiple times
qdiff¶
diff of the current patch and subsequent modifications:
hg qdiff [OPTION]... [FILE]...
Shows a diff which includes the current patch as well as any changes which have
been made in the working directory since the last refresh (thus showing what
the current patch would become after a qrefresh).
Use
hg diff if you only want to see the changes made since the last
qrefresh, or
hg export qtip if you want to see changes made by the
current patch without including changes made since the qrefresh.
Returns 0 on success.
Options:
- -a, --text
- treat all files as text
- -g, --git
- use git extended diff format
- --nodates
- omit dates from diff headers
- -p, --show-function
- show which function each change is in

- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
qfinish¶
move applied patches into repository history:
hg qfinish [-a] [REV]...
Finishes the specified revisions (corresponding to applied patches) by moving
them out of mq control into regular repository history.
Accepts a revision range or the -a/--applied option. If --applied is specified,
all applied mq revisions are removed from mq control. Otherwise, the given
revisions must be at the base of the stack of applied patches.
This can be especially useful if your changes have been applied to an upstream
repository, or if you are about to push your changes to upstream.
Returns 0 on success.
Options:
- -a, --applied
- finish all applied changesets
qfold¶
fold the named patches into the current patch:
hg qfold [-e] [-k] [-m TEXT] [-l FILE] PATCH...
Patches must not yet be applied. Each patch will be successively applied to the
current patch in the order given. If all the patches apply successfully, the
current patch will be refreshed with the new cumulative patch, and the folded
patches will be deleted. With -k/--keep, the folded patch files will not be
removed afterwards.
The header for each folded patch will be concatenated with the current patch
header, separated by a line of
* * *.
Returns 0 on success.
Options:
- -e, --edit
- invoke editor on commit messages
- -k, --keep
- keep folded patch files
- -m,--message <TEXT>
- use text as commit message
- -l,--logfile <FILE>
- read commit message from file
qgoto¶
push or pop patches until named patch is at top of stack:
hg qgoto [OPTION]... PATCH
Returns 0 on success.
Options:
- --keep-changes
- tolerate non-conflicting local changes
- -f, --force
- overwrite any local changes
- --no-backup
- do not save backup copies of files
qguard¶
set or print guards for a patch:
hg qguard [-l] [-n] [PATCH] [-- [+GUARD]... [-GUARD]...]
Guards control whether a patch can be pushed. A patch with no guards is always
pushed. A patch with a positive guard ("+foo") is pushed only if the
hg qselect command has activated it. A patch with a negative guard
("-foo") is never pushed if the
hg qselect command has
activated it.
With no arguments, print the currently active guards. With arguments, set guards
for the named patch.
- Note
- Specifying negative guards now requires '--'.
To set guards on another patch:
hg qguard other.patch -- +2.6.17 -stable
Returns 0 on success.
Options:
- -l, --list
- list all patches and guards
- -n, --none
- drop all guards
print the header of the topmost or specified patch:
hg qheader [PATCH]
Returns 0 on success.
qimport¶
import a patch or existing changeset:
hg qimport [-e] [-n NAME] [-f] [-g] [-P] [-r REV]... [FILE]...
The patch is inserted into the series after the last applied patch. If no
patches have been applied, qimport prepends the patch to the series.
The patch will have the same name as its source file unless you give it a new
one with -n/--name.
You can register an existing patch inside the patch directory with the
-e/--existing flag.
With -f/--force, an existing patch of the same name will be overwritten.
An existing changeset may be placed under mq control with -r/--rev (e.g. qimport
--rev . -n patch will place the current revision under mq control). With
-g/--git, patches imported with --rev will use the git diff format. See the
diffs help topic for information on why this is important for preserving
rename/copy information and permission changes. Use
hg qfinish to
remove changesets from mq control.
To import a patch from standard input, pass - as the patch file. When importing
from standard input, a patch name must be specified using the --name flag.
To import an existing patch while renaming it:
hg qimport -e existing-patch -n new-name
Returns 0 if import succeeded.
Options:
- -e, --existing
- import file in patch directory
- -n,--name <NAME>
- name of patch file
- -f, --force
- overwrite existing files
- -r,--rev <REV[+]>
- place existing revisions under mq control
- -g, --git
- use git extended diff format
- -P, --push
- qpush after importing
[+] marked option can be specified multiple times
qinit¶
init a new queue repository (DEPRECATED):
hg qinit [-c]
The queue repository is unversioned by default. If -c/--create-repo is
specified, qinit will create a separate nested repository for patches (qinit
-c may also be run later to convert an unversioned patch repository into a
versioned one). You can use qcommit to commit changes to this queue
repository.
This command is deprecated. Without -c, it's implied by other relevant commands.
With -c, use
hg init --mq instead.
Options:
- -c, --create-repo
- create queue repository
qnew¶
create a new patch:
hg qnew [-e] [-m TEXT] [-l FILE] PATCH [FILE]...
qnew creates a new patch on top of the currently-applied patch (if any). The
patch will be initialized with any outstanding changes in the working
directory. You may also use -I/--include, -X/--exclude, and/or a list of files
after the patch name to add only changes to matching files to the new patch,
leaving the rest as uncommitted modifications.
-u/--user and -d/--date can be used to set the (given) user and date,
respectively. -U/--currentuser and -D/--currentdate set user to current user
and date to current date.
-e/--edit, -m/--message or -l/--logfile set the patch header as well as the
commit message. If none is specified, the header is empty and the commit
message is '[mq]: PATCH'.
Use the -g/--git option to keep the patch in the git extended diff format. Read
the diffs help topic for more information on why this is important for
preserving permission changes and copy/rename information.
Returns 0 on successful creation of a new patch.
Options:
- -e, --edit
- invoke editor on commit messages
- -f, --force
- import uncommitted changes (DEPRECATED)
- -g, --git
- use git extended diff format
- -U, --currentuser
- add "From: <current user>" to patch
- -u,--user <USER>
- add "From: <USER>" to patch
- -D, --currentdate
- add "Date: <current date>" to patch
- -d,--date <DATE>
- add "Date: <DATE>" to patch
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
- -m,--message <TEXT>
- use text as commit message
- -l,--logfile <FILE>
- read commit message from file
[+] marked option can be specified multiple times
qnext¶
print the name of the next pushable patch:
hg qnext [-s]
Returns 0 on success.
Options:
- -s, --summary
- print first line of patch header
qpop¶
pop the current patch off the stack:
hg qpop [-a] [-f] [PATCH | INDEX]
Without argument, pops off the top of the patch stack. If given a patch name,
keeps popping off patches until the named patch is at the top of the stack.
By default, abort if the working directory contains uncommitted changes. With
--keep-changes, abort only if the uncommitted files overlap with patched
files. With -f/--force, backup and discard changes made to such files.
Return 0 on success.
Options:
- -a, --all
- pop all patches
- -n,--name <NAME>
- queue name to pop (DEPRECATED)
- --keep-changes
- tolerate non-conflicting local changes
- -f, --force
- forget any local changes to patched files
- --no-backup
- do not save backup copies of files
qprev¶
print the name of the preceding applied patch:
hg qprev [-s]
Returns 0 on success.
Options:
- -s, --summary
- print first line of patch header
qpush¶
push the next patch onto the stack:
hg qpush [-f] [-l] [-a] [--move] [PATCH | INDEX]
By default, abort if the working directory contains uncommitted changes. With
--keep-changes, abort only if the uncommitted files overlap with patched
files. With -f/--force, backup and patch over uncommitted changes.
Return 0 on success.
Options:
- --keep-changes
- tolerate non-conflicting local changes
- -f, --force
- apply on top of local changes
- -e, --exact
- apply the target patch to its recorded parent
- -l, --list
- list patch name in commit text
- -a, --all
- apply all patches
- -m, --merge
- merge from another queue (DEPRECATED)
- -n,--name <NAME>
- merge queue name (DEPRECATED)
- --move
- reorder patch series and apply only the patch
- --no-backup
- do not save backup copies of files
qqueue¶
manage multiple patch queues:
hg qqueue [OPTION] [QUEUE]
Supports switching between different patch queues, as well as creating new patch
queues and deleting existing ones.
Omitting a queue name or specifying -l/--list will show you the registered
queues - by default the "normal" patches queue is registered. The
currently active queue will be marked with "(active)". Specifying
--active will print only the name of the active queue.
To create a new queue, use -c/--create. The queue is automatically made active,
except in the case where there are applied patches from the currently active
queue in the repository. Then the queue will only be created and switching
will fail.
To delete an existing queue, use --delete. You cannot delete the currently
active queue.
Returns 0 on success.
Options:
- -l, --list
- list all available queues
- --active
- print name of active queue
- -c, --create
- create new queue
- --rename
- rename active queue
- --delete
- delete reference to queue
- --purge
- delete queue, and remove patch dir
qrefresh¶
update the current patch:
hg qrefresh [-I] [-X] [-e] [-m TEXT] [-l FILE] [-s] [FILE]...
If any file patterns are provided, the refreshed patch will contain only the
modifications that match those patterns; the remaining modifications will
remain in the working directory.
If -s/--short is specified, files currently included in the patch will be
refreshed just like matched files and remain in the patch.
If -e/--edit is specified, Mercurial will start your configured editor for you
to enter a message. In case qrefresh fails, you will find a backup of your
message in
.hg/last-message.txt.
hg add/remove/copy/rename work as usual, though you might want to use git-style
patches (-g/--git or [diff] git=1) to track copies and renames. See the diffs
help topic for more information on the git diff format.
Returns 0 on success.
Options:
- -e, --edit
- invoke editor on commit messages
- -g, --git
- use git extended diff format
- -s, --short
- refresh only files already in the patch and specified
files
- -U, --currentuser
- add/update author field in patch with current user
- -u,--user <USER>
- add/update author field in patch with given user
- -D, --currentdate
- add/update date field in patch with current date
- -d,--date <DATE>
- add/update date field in patch with given date
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
- -m,--message <TEXT>
- use text as commit message
- -l,--logfile <FILE>
- read commit message from file
[+] marked option can be specified multiple times
qrename¶
rename a patch:
hg qrename PATCH1 [PATCH2]
With one argument, renames the current patch to PATCH1. With two arguments,
renames PATCH1 to PATCH2.
Returns 0 on success.
qrestore¶
restore the queue state saved by a revision (DEPRECATED):
hg qrestore [-d] [-u] REV
This command is deprecated, use
hg rebase instead.
Options:
- -d, --delete
- delete save entry
- -u, --update
- update queue working directory
qsave¶
save current queue state (DEPRECATED):
hg qsave [-m TEXT] [-l FILE] [-c] [-n NAME] [-e] [-f]
This command is deprecated, use
hg rebase instead.
Options:
- -c, --copy
- copy patch directory
- -n,--name <NAME>
- copy directory name
- -e, --empty
- clear queue status file
- -f, --force
- force copy
- -m,--message <TEXT>
- use text as commit message
- -l,--logfile <FILE>
- read commit message from file
qselect¶
set or print guarded patches to push:
hg qselect [OPTION]... [GUARD]...
Use the
hg qguard command to set or print guards on patch, then use
qselect to tell mq which guards to use. A patch will be pushed if it has no
guards or any positive guards match the currently selected guard, but will not
be pushed if any negative guards match the current guard. For example:
qguard foo.patch -- -stable (negative guard)
qguard bar.patch +stable (positive guard)
qselect stable
This activates the "stable" guard. mq will skip foo.patch (because it
has a negative match) but push bar.patch (because it has a positive match).
With no arguments, prints the currently active guards. With one argument, sets
the active guard.
Use -n/--none to deactivate guards (no other arguments needed). When no guards
are active, patches with positive guards are skipped and patches with negative
guards are pushed.
qselect can change the guards on applied patches. It does not pop guarded
patches by default. Use --pop to pop back to the last applied patch that is
not guarded. Use --reapply (which implies --pop) to push back to the current
patch afterwards, but skip guarded patches.
Use -s/--series to print a list of all guards in the series file (no other
arguments needed). Use -v for more information.
Returns 0 on success.
Options:
- -n, --none
- disable all guards
- -s, --series
- list all guards in series file
- --pop
- pop to before first guarded applied patch
- --reapply
- pop, then reapply patches
qseries¶
print the entire series file:
hg qseries [-ms]
Returns 0 on success.
Options:
- -m, --missing
- print patches not in series
- -s, --summary
- print first line of patch header
qtop¶
print the name of the current patch:
hg qtop [-s]
Returns 0 on success.
Options:
- -s, --summary
- print first line of patch header
qunapplied¶
print the patches not yet applied:
hg qunapplied [-1] [-s] [PATCH]
Returns 0 on success.
Options:
- -1, --first
- show only the first patch
- -s, --summary
- print first line of patch header
notify¶
hooks for sending email push notifications
This extension implements hooks to send email notifications when changesets are
sent from or received by the local repository.
First, enable the extension as explained in
hg help extensions, and
register the hook you want to run.
incoming and
changegroup
hooks are run when changesets are received, while
outgoing hooks are
for changesets sent to another repository:
[hooks]
# one email for each incoming changeset
incoming.notify = python:hgext.notify.hook
# one email for all incoming changesets
changegroup.notify = python:hgext.notify.hook
# one email for all outgoing changesets
outgoing.notify = python:hgext.notify.hook
This registers the hooks. To enable notification, subscribers must be assigned
to repositories. The
[usersubs] section maps multiple repositories to a
given recipient. The
[reposubs] section maps multiple recipients to a
single repository:
[usersubs]
# key is subscriber email, value is a comma-separated list of repo patterns
user@host = pattern
[reposubs]
# key is repo pattern, value is a comma-separated list of subscriber emails
pattern = user@host
A
pattern is a
glob matching the absolute path to a repository,
optionally combined with a revset expression. A revset expression, if present,
is separated from the glob by a hash. Example:
[reposubs]
*/widgets#branch(release) = qa-team@example.com
This sends to
qa-team@example.com whenever a changeset on the
release branch triggers a notification in any repository ending in
widgets.
In order to place them under direct user management,
[usersubs] and
[reposubs] sections may be placed in a separate
hgrc file and
incorporated by reference:
[notify]
config = /path/to/subscriptionsfile
Notifications will not be sent until the
notify.test value is set to
False; see below.
Notifications content can be tweaked with the following configuration entries:
- notify.test
- If True, print messages to stdout instead of sending
them. Default: True.
- notify.sources
- Space-separated list of change sources. Notifications are
activated only when a changeset's source is in this list. Sources may
be:
- serve
-
changesets received via http or ssh
- pull
-
changesets received via hg pull
- unbundle
-
changesets received via hg unbundle
- push
-
changesets sent or received via hg push
- bundle
-
changesets sent via hg unbundle
Default: serve.
- notify.strip
- Number of leading slashes to strip from url paths. By
default, notifications reference repositories with their absolute path.
notify.strip lets you turn them into relative paths. For example,
notify.strip=3 will change /long/path/repository into
repository. Default: 0.
- notify.domain
- Default email domain for sender or recipients with no
explicit domain.
- notify.style
- Style file to use when formatting emails.
- notify.template
- Template to use when formatting emails.
- notify.incoming
- Template to use when run as an incoming hook, overriding
notify.template.
- notify.outgoing
- Template to use when run as an outgoing hook, overriding
notify.template.
- notify.changegroup
- Template to use when running as a changegroup hook,
overriding notify.template.
- notify.maxdiff
- Maximum number of diff lines to include in notification
email. Set to 0 to disable the diff, or -1 to include all of it. Default:
300.
- notify.maxsubject
- Maximum number of characters in email's subject line.
Default: 67.
- notify.diffstat
- Set to True to include a diffstat before diff content.
Default: True.
- notify.merge
- If True, send notifications for merge changesets. Default:
True.
- notify.mbox
- If set, append mails to this mbox file instead of sending.
Default: None.
- notify.fromauthor
- If set, use the committer of the first changeset in a
changegroup for the "From" field of the notification mail. If
not set, take the user from the pushing repo. Default: False.
If set, the following entries will also be used to customize the notifications:
- email.from
- Email From address to use if none can be found in
the generated email content.
- web.baseurl
- Root repository URL to combine with repository paths when
making references. See also notify.strip.
browse command output with an external pager
To set the pager that should be used, set the application variable:
[pager]
pager = less -FRX
If no pager is set, the pager extensions uses the environment variable $PAGER.
If neither pager.pager, nor $PAGER is set, no pager is used.
You can disable the pager for certain commands by adding them to the
pager.ignore list:
[pager]
ignore = version, help, update
You can also enable the pager only for certain commands using pager.attend.
Below is the default list of commands to be paged:
[pager]
attend = annotate, cat, diff, export, glog, log, qdiff
Setting pager.attend to an empty value will cause all commands to be paged.
If pager.attend is present, pager.ignore will be ignored.
Lastly, you can enable and disable paging for individual commands with the
attend-<command> option. This setting takes precedence over existing
attend and ignore options and defaults:
[pager]
attend-cat = false
To ignore global commands like
hg version or
hg help, you have to
specify them in your user configuration file.
The --pager=... option can also be used to control when the pager is used. Use a
boolean value like yes, no, on, off, or use auto for normal behavior.
patchbomb¶
command to send changesets as (a series of) patch emails
The series is started off with a "[PATCH 0 of N]" introduction, which
describes the series as a whole.
Each patch email has a Subject line of "[PATCH M of N] ...", using the
first line of the changeset description as the subject text. The message
contains two or three body parts:
- •
- The changeset description.
- •
- [Optional] The result of running diffstat on the
patch.
- •
- The patch itself, as generated by hg export.
Each message refers to the first in the series using the In-Reply-To and
References headers, so they will show up as a sequence in threaded mail and
news readers, and in mail archives.
To configure other defaults, add a section like this to your configuration file:
[email]
from = My Name <my@email>
to = recipient1, recipient2, ...
cc = cc1, cc2, ...
bcc = bcc1, bcc2, ...
reply-to = address1, address2, ...
Use
[patchbomb] as configuration section name if you need to override
global
[email] address settings.
Then you can use the
hg email command to mail a series of changesets as a
patchbomb.
You can also either configure the method option in the email section to be a
sendmail compatible mailer or fill out the [smtp] section so that the
patchbomb extension can automatically send patchbombs directly from the
commandline. See the [email] and [smtp] sections in
hgrc(5) for details.
Commands¶
email¶
send changesets by email:
hg email [OPTION]... [DEST]...
By default, diffs are sent in the format generated by
hg export, one per
message. The series starts with a "[PATCH 0 of N]" introduction,
which describes the series as a whole.
Each patch email has a Subject line of "[PATCH M of N] ...", using the
first line of the changeset description as the subject text. The message
contains two or three parts. First, the changeset description.
With the -d/--diffstat option, if the diffstat program is installed, the result
of running diffstat on the patch is inserted.
Finally, the patch itself, as generated by
hg export.
With the -d/--diffstat or --confirm options, you will be presented with a final
summary of all messages and asked for confirmation before the messages are
sent.
By default the patch is included as text in the email body for easy reviewing.
Using the -a/--attach option will instead create an attachment for the patch.
With -i/--inline an inline attachment will be created. You can include a patch
both as text in the email body and as a regular or an inline attachment by
combining the -a/--attach or -i/--inline with the --body option.
With -o/--outgoing, emails will be generated for patches not found in the
destination repository (or only those which are ancestors of the specified
revisions if any are provided)
With -b/--bundle, changesets are selected as for --outgoing, but a single email
containing a binary Mercurial bundle as an attachment will be sent.
With -m/--mbox, instead of previewing each patchbomb message in a pager or
sending the messages directly, it will create a UNIX mailbox file with the
patch emails. This mailbox file can be previewed with any mail user agent
which supports UNIX mbox files.
With -n/--test, all steps will run, but mail will not be sent. You will be
prompted for an email recipient address, a subject and an introductory message
describing the patches of your patchbomb. Then when all is done, patchbomb
messages are displayed. If the PAGER environment variable is set, your pager
will be fired up once for each patchbomb message, so you can verify everything
is alright.
In case email sending fails, you will find a backup of your series introductory
message in
.hg/last-email.txt.
Examples:
hg email -r 3000 # send patch 3000 only
hg email -r 3000 -r 3001 # send patches 3000 and 3001
hg email -r 3000:3005 # send patches 3000 through 3005
hg email 3000 # send patch 3000 (deprecated)
hg email -o # send all patches not in default
hg email -o DEST # send all patches not in DEST
hg email -o -r 3000 # send all ancestors of 3000 not in default
hg email -o -r 3000 DEST # send all ancestors of 3000 not in DEST
hg email -b # send bundle of all patches not in default
hg email -b DEST # send bundle of all patches not in DEST
hg email -b -r 3000 # bundle of all ancestors of 3000 not in default
hg email -b -r 3000 DEST # bundle of all ancestors of 3000 not in DEST
hg email -o -m mbox && # generate an mbox file...
mutt -R -f mbox # ... and view it with mutt
hg email -o -m mbox && # generate an mbox file ...
formail -s sendmail \ # ... and use formail to send from the mbox
-bm -t < mbox # ... using sendmail
Before using this command, you will need to enable email in your hgrc. See the
[email] section in
hgrc(5) for details.

[+] marked option can be specified multiple times
progress¶
show progress bars for some actions
This extension uses the progress information logged by hg commands to draw
progress bars that are as informative as possible. Some progress bars only
offer indeterminate information, while others have a definite end point.
The following settings are available:
[progress]
delay = 3 # number of seconds (float) before showing the progress bar
changedelay = 1 # changedelay: minimum delay before showing a new topic.
# If set to less than 3 * refresh, that value will
# be used instead.
refresh = 0.1 # time in seconds between refreshes of the progress bar
format = topic bar number estimate # format of the progress bar
width = <none> # if set, the maximum width of the progress information
# (that is, min(width, term width) will be used)
clear-complete = True # clear the progress bar after it's done
disable = False # if true, don't show a progress bar
assume-tty = False # if true, ALWAYS show a progress bar, unless
# disable is given
Valid entries for the format field are topic, bar, number, unit, estimate,
speed, and item. item defaults to the last 20 characters of the item, but this
can be changed by adding either
-<num> which would take the last
num characters, or
+<num> for the first num characters.
purge¶
command to delete untracked files from the working directory
Commands¶
purge¶
removes files not tracked by Mercurial:
hg purge [OPTION]... [DIR]...
Delete files not known to Mercurial. This is useful to test local and
uncommitted changes in an otherwise-clean source tree.
This means that purge will delete the following by default:
- •
- Unknown files: files marked with "?" by hg
status
- •
- Empty directories: in fact Mercurial ignores directories
unless they contain files under source control management
But it will leave untouched:
- •
- Modified and unmodified tracked files
- •
- Ignored files (unless --all is specified)
- •
- New files added to the repository (with hg add)
The --files and --dirs options can be used to direct purge to delete only files,
only directories, or both. If neither option is given, both will be deleted.
If directories are given on the command line, only files in these directories
are considered.
Be careful with purge, as you could irreversibly delete some files you forgot to
add to the repository. If you only want to print the list of files that this
program would delete, use the --print option.
Options:
- -a, --abort-on-err
- abort if an error occurs
- --all
- purge ignored files too
- --dirs
- purge empty directories
- --files
- purge files
- -p, --print
- print filenames instead of deleting them
- -0, --print0
- end filenames with NUL, for use with xargs (implies
-p/--print)
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
rebase¶
command to move sets of revisions to a different ancestor
This extension lets you rebase changesets in an existing Mercurial repository.
For more information:
http://mercurial.selenic.com/wiki/RebaseExtension
Commands¶
rebase¶
move changeset (and descendants) to a different branch:
hg rebase [-s REV | -b REV] [-d REV] [OPTION]
Rebase uses repeated merging to graft changesets from one part of history (the
source) onto another (the destination). This can be useful for linearizing
local changes relative to a master development tree.
You should not rebase changesets that have already been shared with others.
Doing so will force everybody else to perform the same rebase or they will end
up with duplicated changesets after pulling in your rebased changesets.
In its default configuration, Mercurial will prevent you from rebasing published
changes. See
hg help phases for details.
If you don't specify a destination changeset (
-d/--dest), rebase uses
the current branch tip as the destination. (The destination changeset is not
modified by rebasing, but new changesets are added as its descendants.)
You can specify which changesets to rebase in two ways: as a "source"
changeset or as a "base" changeset. Both are shorthand for a
topologically related set of changesets (the "source branch"). If
you specify source (
-s/--source), rebase will rebase that changeset
and all of its descendants onto dest. If you specify base (
-b/--base),
rebase will select ancestors of base back to but not including the common
ancestor with dest. Thus,
-b is less precise but more convenient than
-s: you can specify any changeset in the source branch, and rebase will
select the whole branch. If you specify neither
-s nor
-b,
rebase uses the parent of the working directory as the base.
For advanced usage, a third way is available through the
--rev option. It
allows you to specify an arbitrary set of changesets to rebase. Descendants of
revs you specify with this option are not automatically included in the
rebase.
By default, rebase recreates the changesets in the source branch as descendants
of dest and then destroys the originals. Use
--keep to preserve the
original source changesets. Some changesets in the source branch (e.g. merges
from the destination branch) may be dropped if they no longer contribute any
change.
One result of the rules for selecting the destination changeset and source
branch is that, unlike
merge, rebase will do nothing if you are at the
branch tip of a named branch with two heads. You need to explicitly specify
source and/or destination (or
update to the other head, if it's the
head of the intended source branch).
If a rebase is interrupted to manually resolve a merge, it can be continued with
--continue/-c or aborted with --abort/-a.
Returns 0 on success, 1 if nothing to rebase or there are unresolved conflicts.
Options:
- -s,--source <REV>
- rebase from the specified changeset
- -b,--base <REV>
- rebase from the base of the specified changeset (up to
greatest common ancestor of base and dest)
- -r,--rev <REV[+]>
- rebase these revisions
- -d,--dest <REV>
- rebase onto the specified changeset
- --collapse
- collapse the rebased changesets
- -m,--message <TEXT>
- use text as collapse commit message
- -e, --edit
- invoke editor on commit messages
- -l,--logfile <FILE>
- read collapse commit message from file
- --keep
- keep original changesets
- --keepbranches
- keep original branch names
- -D, --detach
- (DEPRECATED)
- -t,--tool <VALUE>
- specify merge tool
- -c, --continue
- continue an interrupted rebase
- -a, --abort
- abort an interrupted rebase
- --style <STYLE>
- display using template map file (DEPRECATED)
- -T,--template <TEMPLATE>
- display with template
[+] marked option can be specified multiple times
record¶
commands to interactively select changes for commit/qrefresh
Commands¶
qrecord¶
interactively record a new patch:
hg qrecord [OPTION]... PATCH [FILE]...
See
hg help qnew &
hg help record for more information and
usage.
record¶
interactively select changes to commit:
hg record [OPTION]... [FILE]...
If a list of files is omitted, all changes reported by
hg status will be
candidates for recording.
See
hg help dates for a list of formats valid for -d/--date.
You will be prompted for whether to record changes to each modified file, and
for files with multiple changes, for each change to use. For each query, the
following responses are possible:
y - record this change
n - skip this change
e - edit this change manually
s - skip remaining changes to this file
f - record remaining changes to this file
d - done, skip remaining changes and files
a - record all changes to all remaining files
q - quit, recording no changes
? - display help
This command is not available when committing a merge.

[+] marked option can be specified multiple times
relink¶
recreates hardlinks between repository clones
Commands¶
relink¶
recreate hardlinks between two repositories:
hg relink [ORIGIN]
When repositories are cloned locally, their data files will be hardlinked so
that they only use the space of a single repository.
Unfortunately, subsequent pulls into either repository will break hardlinks for
any files touched by the new changesets, even if both repositories end up
pulling the same changes.
Similarly, passing --rev to "hg clone" will fail to use any hardlinks,
falling back to a complete copy of the source repository.
This command lets you recreate those hardlinks and reclaim that wasted space.
This repository will be relinked to share space with ORIGIN, which must be on
the same local disk. If ORIGIN is omitted, looks for
"default-relink", then "default", in [paths].
Do not attempt any read operations on this repository while the command is
running. (Both repositories will be locked against writes.)
schemes¶
extend schemes with shortcuts to repository swarms
This extension allows you to specify shortcuts for parent URLs with a lot of
repositories to act like a scheme, for example:
[schemes]
py = http://code.python.org/hg/
After that you can use it like:
hg clone py://trunk/
Additionally there is support for some more complex schemas, for example used by
Google Code:
[schemes]
gcode = http://{1}.googlecode.com/hg/
The syntax is taken from Mercurial templates, and you have unlimited number of
variables, starting with
{1} and continuing with
{2},
{3}
and so on. This variables will receive parts of URL supplied, split by
/. Anything not specified as
{part} will be just appended to an
URL.
For convenience, the extension adds these schemes by default:
[schemes]
py = http://hg.python.org/
bb = https://bitbucket.org/
bb+ssh = ssh://hg@bitbucket.org/
gcode = https://{1}.googlecode.com/hg/
kiln = https://{1}.kilnhg.com/Repo/
You can override a predefined scheme by defining a new scheme with the same
name.
share¶
share a common history between several working directories
Commands¶
share¶
create a new shared repository:
hg share [-U] SOURCE [DEST]
Initialize a new repository and working directory that shares its history with
another repository.
- Note
- using rollback or extensions that destroy/modify history
(mq, rebase, etc.) can cause considerable confusion with shared clones. In
particular, if two shared clones are both updated to the same changeset,
and one of them destroys that changeset with rollback, the other clone
will suddenly stop working: all operations will fail with "abort:
working directory has unknown parent". The only known workaround is
to use debugsetparents on the broken clone to reset it to a changeset that
still exists.
Options:
- -U, --noupdate
- do not create a working copy
unshare¶
convert a shared repository to a normal one:
hg unshare
Copy the store data to the repo and remove the sharedpath data.
shelve¶
save and restore changes to the working directory
The "hg shelve" command saves changes made to the working directory
and reverts those changes, resetting the working directory to a clean state.
Later on, the "hg unshelve" command restores the changes saved by
"hg shelve". Changes can be restored even after updating to a
different parent, in which case Mercurial's merge machinery will resolve any
conflicts if necessary.
You can have more than one shelved change outstanding at a time; each shelved
change has a distinct name. For details, see the help for "hg
shelve".
Commands¶
shelve¶
save and set aside changes from the working directory:
hg shelve [OPTION]... [FILE]...
Shelving takes files that "hg status" reports as not clean, saves the
modifications to a bundle (a shelved change), and reverts the files so that
their state in the working directory becomes clean.
To restore these changes to the working directory, using "hg
unshelve"; this will work even if you switch to a different commit.
When no files are specified, "hg shelve" saves all not-clean files. If
specific files or directories are named, only changes to those files are
shelved.
Each shelved change has a name that makes it easier to find later. The name of a
shelved change defaults to being based on the active bookmark, or if there is
no active bookmark, the current named branch. To specify a different name, use
--name.
To see a list of existing shelved changes, use the
--list option. For
each shelved change, this will print its name, age, and description; use
--patch or
--stat for more details.
To delete specific shelved changes, use
--delete. To delete all shelved
changes, use
--cleanup.
Options:
- -A, --addremove
- mark new/missing files as added/removed before
shelving
- --cleanup
- delete all shelved changes
- --date <DATE>
- shelve with the specified commit date
- -d, --delete
- delete the named shelved change(s)
- -e, --edit
- invoke editor on commit messages
- -l, --list
- list current shelves
- -m,--message <TEXT>
- use text as shelve message
- -n,--name <NAME>
- use the given name for the shelved commit
- -p, --patch
- show patch
- --stat
- output diffstat-style summary of changes
- -I,--include <PATTERN[+]>
- include names matching the given patterns
- -X,--exclude <PATTERN[+]>
- exclude names matching the given patterns
[+] marked option can be specified multiple times
unshelve¶
restore a shelved change to the working directory:
hg unshelve [SHELVED]
This command accepts an optional name of a shelved change to restore. If none is
given, the most recent shelved change is used.
If a shelved change is applied successfully, the bundle that contains the
shelved changes is deleted afterwards.
Since you can restore a shelved change on top of an arbitrary commit, it is
possible that unshelving will result in a conflict between your changes and
the commits you are unshelving onto. If this occurs, you must resolve the
conflict, then use
--continue to complete the unshelve operation. (The
bundle will not be deleted until you successfully complete the unshelve.)
(Alternatively, you can use
--abort to abandon an unshelve that causes a
conflict. This reverts the unshelved changes, and does not delete the bundle.)
Options:
- -a, --abort
- abort an incomplete unshelve operation
- -c, --continue
- continue an incomplete unshelve operation
- --keep
- keep shelve after unshelving
- --date <DATE>
- set date for temporary commits (DEPRECATED)
strip¶
strip changesets and their descendents from history
This extension allows you to strip changesets and all their descendants from the
repository. See the command help for details.
Commands¶
strip¶
strip changesets and all their descendants from the repository:
hg strip [-k] [-f] [-n] [-B bookmark] [-r] REV...
The strip command removes the specified changesets and all their descendants. If
the working directory has uncommitted changes, the operation is aborted unless
the --force flag is supplied, in which case changes will be discarded.
If a parent of the working directory is stripped, then the working directory
will automatically be updated to the most recent available ancestor of the
stripped parent after the operation completes.
Any stripped changesets are stored in
.hg/strip-backup as a bundle (see
hg help bundle and
hg help unbundle). They can be restored by
running
hg unbundle .hg/strip-backup/BUNDLE, where BUNDLE is the bundle
file created by the strip. Note that the local revision numbers will in
general be different after the restore.
Use the --no-backup option to discard the backup bundle once the operation
completes.
Strip is not a history-rewriting operation and can be used on changesets in the
public phase. But if the stripped changesets have been pushed to a remote
repository you will likely pull them again.
Return 0 on success.
Options:
- -r,--rev <REV[+]>
- strip specified revision (optional, can specify revisions
without this option)
- -f, --force
- force removal of changesets, discard uncommitted changes
(no backup)
- --no-backup
- no backups
- --nobackup
- no backups (DEPRECATED)
- -n
- ignored (DEPRECATED)
- -k, --keep
- do not modify working copy during strip
- -B,--bookmark <VALUE>
- remove revs only reachable from given bookmark
[+] marked option can be specified multiple times
transplant¶
command to transplant changesets from another branch
This extension allows you to transplant changes to another parent revision,
possibly in another repository. The transplant is done using 'diff' patches.
Transplanted patches are recorded in .hg/transplant/transplants, as a map from a
changeset hash to its hash in the source repository.
Commands¶
transplant¶
transplant changesets from another branch:
hg transplant [-s REPO] [-b BRANCH [-a]] [-p REV] [-m REV] [REV]...
Selected changesets will be applied on top of the current working directory with
the log of the original changeset. The changesets are copied and will thus
appear twice in the history with different identities.
Consider using the graft command if everything is inside the same repository -
it will use merges and will usually give a better result. Use the rebase
extension if the changesets are unpublished and you want to move them instead
of copying them.
If --log is specified, log messages will have a comment appended of the form:
(transplanted from CHANGESETHASH)
You can rewrite the changelog message with the --filter option. Its argument
will be invoked with the current changelog message as $1 and the patch as $2.
--source/-s specifies another repository to use for selecting changesets, just
as if it temporarily had been pulled. If --branch/-b is specified, these
revisions will be used as heads when deciding which changesets to transplant,
just as if only these revisions had been pulled. If --all/-a is specified, all
the revisions up to the heads specified with --branch will be transplanted.
Example:
- •
- transplant all changes up to REV on top of your current
revision:
hg transplant --branch REV --all
You can optionally mark selected transplanted changesets as merge changesets.
You will not be prompted to transplant any ancestors of a merged transplant,
and you can merge descendants of them normally instead of transplanting them.
Merge changesets may be transplanted directly by specifying the proper parent
changeset by calling
hg transplant --parent.
If no merges or revisions are provided,
hg transplant will start an
interactive changeset browser.
If a changeset application fails, you can fix the merge by hand and then resume
where you left off by calling
hg transplant --continue/-c.
Options:
- -s,--source <REPO>
- transplant changesets from REPO
- -b,--branch <REV[+]>
- use this source changeset as head
- -a, --all
- pull all changesets up to the --branch revisions
- -p,--prune <REV[+]>
- skip over REV
- -m,--merge <REV[+]>
- merge at REV
- --parent <REV>
- parent to choose when transplanting merge
- -e, --edit
- invoke editor on commit messages
- --log
- append transplant info to log message
- -c, --continue
- continue last transplant session after fixing
conflicts
- --filter <CMD>
- filter changesets through command
[+] marked option can be specified multiple times
win32mbcs¶
allow the use of MBCS paths with problematic encodings
Some MBCS encodings are not good for some path operations (i.e. splitting path,
case conversion, etc.) with its encoded bytes. We call such a encoding (i.e.
shift_jis and big5) as "problematic encoding". This extension can be
used to fix the issue with those encodings by wrapping some functions to
convert to Unicode string before path operation.
This extension is useful for:
- •
- Japanese Windows users using shift_jis encoding.
- •
- Chinese Windows users using big5 encoding.
- •
- All users who use a repository with one of problematic
encodings on case-insensitive file system.
This extension is not needed for:
- •
- Any user who use only ASCII chars in path.
- •
- Any user who do not use any of problematic encodings.
Note that there are some limitations on using this extension:
- •
- You should use single encoding in one repository.
- •
- If the repository path ends with 0x5c, .hg/hgrc cannot be
read.
- •
- win32mbcs is not compatible with fixutf8 extension.
By default, win32mbcs uses encoding.encoding decided by Mercurial. You can
specify the encoding by config option:
[win32mbcs]
encoding = sjis
It is useful for the users who want to commit with UTF-8 log message.
win32text¶
perform automatic newline conversion (DEPRECATED)
Deprecation: The win32text extension requires each user to configure the
extension again and again for each clone since the configuration is not copied
when cloning.
We have therefore made the
eol as an alternative. The
eol uses a
version controlled file for its configuration and each clone will therefore
use the right settings from the start.
To perform automatic newline conversion, use:
[extensions]
win32text =
[encode]
** = cleverencode:
# or ** = macencode:
[decode]
** = cleverdecode:
# or ** = macdecode:
If not doing conversion, to make sure you do not commit CRLF/CR by accident:
[hooks]
pretxncommit.crlf = python:hgext.win32text.forbidcrlf
# or pretxncommit.cr = python:hgext.win32text.forbidcr
To do the same check on a server to prevent CRLF/CR from being pushed or pulled:
[hooks]
pretxnchangegroup.crlf = python:hgext.win32text.forbidcrlf
# or pretxnchangegroup.cr = python:hgext.win32text.forbidcr
zeroconf¶
discover and advertise repositories on the local network
The zeroconf extension will advertise
hg serve instances over DNS-SD so
that they can be discovered using the
hg paths command without knowing
the server's address.
To allow other people to discover your repository using run
hg serve in
your repository:
$ cd test
$ hg serve
You can discover Zeroconf-enabled repositories by running
hg paths:
$ hg paths
zc-test = http://example.com:8000/test
FILES¶
- /etc/mercurial/hgrc, $HOME/.hgrc,
.hg/hgrc
-
This file contains defaults and configuration. Values in .hg/hgrc
override those in $HOME/.hgrc, and these override settings made in
the global /etc/mercurial/hgrc configuration. See hgrc(5)
for details of the contents and format of these files.
- .hgignore
-
This file contains regular expressions (one per line) that describe file
names that should be ignored by hg. For details, see
hgignore(5).
- .hgsub
-
This file defines the locations of all subrepositories, and tells where the
subrepository checkouts came from. For details, see hg help
subrepos.
- .hgsubstate
-
This file is where Mercurial stores all nested repository states. NB:
This file should not be edited manually.
- .hgtags
-
This file contains changeset hash values and text tag names (one of each
separated by spaces) that correspond to tagged versions of the repository
contents. The file content is encoded using UTF-8.
- .hg/last-message.txt
-
This file is used by hg commit to store a backup of the commit
message in case the commit fails.
- .hg/localtags
-
This file can be used to define local tags which are not shared among
repositories. The file format is the same as for .hgtags, but it is
encoded using the local system encoding.
Some commands (e.g. revert) produce backup files ending in
.orig, if the
.orig file already exists and is not tracked by Mercurial, it will be
overwritten.
BUGS¶
Probably lots, please post them to the mailing list (see Resources below) when
you find them.
