debcheckout - checkout the development repository of a Debian package
- debcheckout [OPTIONS] PACKAGE
- debcheckout [OPTIONS] REPOSITORY_URL
- debcheckout --help
retrieves the information about the Version Control System
used to maintain a given Debian package (the PACKAGE
then checks out the latest (potentially unreleased) version of the package
from its repository. By default the repository is checked out to the
directory; this can be overridden by providing the
The information about where the repository is available is expected to be found
fields available in the source package record. For example,
package exposes such information with a field like
, you can see it by
grepping through apt-cache showsrc vim
If more than one source package record containing Vcs-*
will select the record with the highest version
number. Alternatively, a particular version may be selected from those
available by specifying the package name as PACKAGE
If you already know the URL of a given repository you can invoke
directly on it, but you will probably need to pass the
flag. That is, some heuristics are in use to guess the
repository type from the URL; if they fail, you might want to override the
guessed type using -t
The currently supported version control systems are: Arch (arch), Bazaar (bzr),
CVS (cvs), Darcs (darcs), Git (git), Mercurial (hg) and Subversion (svn).
- -a, --auth
- Work in authenticated mode; this means that for known
repositories (mainly those hosted on https://alioth.debian.org) URL
rewriting is attempted before checking out, to ensure that the repository
can be committed to. For example, for Subversion repositories hosted on
alioth this means that svn+ssh://svn.debian.org/... will be used
instead of svn://svn.debian.org/....
There are built-in rules for alioth.debian.org and github.com. Other hosts
can be configured using DEBCHECKOUT_AUTH_URLS.
- -d, --details
- Only print a list of detailed information about the package
repository, without checking it out; the output format is a list of
fields, each field being a pair of TAB-separated field name and field
value. The actual fields depend on the repository type. This action might
require a network connection to the remote repository.
Also see -p. This option and -p are mutually exclusive.
- -h, --help
- Print a detailed help message and exit.
- -p, --print
- Only print a summary about package repository information,
without checking it out; the output format is TAB-separated with two
fields: repository type, repository URL. This action works offline, it
only uses "static" information as known by APT's cache.
Also see -d. This option and -d are mutually exclusive.
- -P package, --package
- When checking out a repository URL, instead of trying to
guess the package name from the URL, use this package name.
- -t TYPE, --type TYPE
- Override the repository type (which defaults to some
heuristics based on the URL or, in case of heuristic failure, the fallback
"svn"); should be one of the currently supported repository
- -u USERNAME, --user
- Specify the login name to be used in authenticated mode
(see -a). This option implies -a: you don't need to specify
- -f FILE, --file FILE
- Specify that the named file should be extracted from the
repository and placed in the destination directory. May be used more than
once to extract multiple files.
- Some packages only place the debian directory in
version control. debcheckout can retrieve the remaining parts of
the source using apt-get source and move the files into the
- Only use the repository.
- auto (default)
- If the repository only contains the debian
directory, retrieve the source package, unpack it, and also place the
.orig.tar.gz file into the current directory. Else, do
- Always retrieve the .orig.tar.gz file, but do not
- Always retrieve the .orig.tar.gz file, and if the
repository only contains the debian directory, unpack it.
- --git-track BRANCHES
- Specify a list of remote branches which will be set up for
tracking (as in git branch --track, see
git-branch(1)) after the remote Git repository has been cloned. The
list should be given as a space-separated list of branch names.
As a shorthand, the string " *" can be given to require
tracking of all remote branches.
The two configuration files /etc/devscripts.conf
are sourced by a shell in that order to set configuration variables. Command
line options can be used to override configuration file settings. Environment
variable settings are ignored for this purpose. The currently recognised
- This variable should be a space separated list of Perl
regular expressions and replacement texts, which must come in pairs:
REGEXP TEXT REGEXP TEXT ... and so on. Each
pair denotes a substitution which is applied to repository URLs if other
built-in means of building URLs for authenticated mode (see -a)
References to matching substrings in the replacement texts are allowed as
usual in Perl by the means of $1,
$2, ... and so on.
This setting can be used to enable authenticated mode for most repositories
out there. Note that the Debian repositories on alioth.debian.org
($vcs.debian.org) are implicitly defined.
Here is a sample snippet suitable for the configuration files:
Note that whitespace is not allowed in either regexps or replacement texts.
Also, given that configuration files are sourced by a shell, you probably
want to use single quotes around the value of this variable.
- This variable determines under what scenarios the
associated orig.tar.gz for a package will be downloaded. See the
--source option for a description of the values.
- This variable sets the username for authenticated mode. It
can be overridden with the --user option. Setting this variable
does not imply the use of authenticated mode, it still has to be activated
