.SH NAME
.P
opam\N'45'pin \N'45' Pin a given package to a specific version or source\N'46'
.SH SYNOPSIS
.P
\fBopam pin\fR [\fIOPTION\fR]\N'46'\N'46'\N'46' [\fICOMMAND\fR] [\fIARG\fR]\N'46'\N'46'\N'46'
.SH DESCRIPTION
.P
This command allows local customisation of the packages in a given switch\N'46' A pinning can either just enforce a given version, or provide a local, editable version of the definition of the package\N'46' It is also possible to create a new package just by pinning a non\N'45'existing package name\N'46'
.P
Any customisation is available through the \fIedit\fR subcommand, but the command\N'45'line gives facility for altering the source URL of the package, since it is the most common use: \fIopam pin add PKG URL\fR modifies package \fIPKG\fR to fetch its source from \fIURL\fR\N'46' If a package definition is found in the package\N'39's source tree, it will be used locally\N'46'
.P
If (or \fI\N'45'\fR) is specified, the package is pinned without a source archive\N'46' The package name can be omitted if the target is a directory containing one or more valid package definitions (this allows to do e\N'46'g\N'46' \fIopam pin add \N'46'\fR from a source directory\N'46'
.P
If \fIPACKAGE\fR has the form \fIname\N'46'version\fR, the pinned package will be considered as version \fIversion\fR by opam\N'46' Beware that this doesn\N'39't relate with the version of the source actually used for the package\N'46'
.P
The default subcommand is \fIlist\fR if there are no further arguments, and \fIadd\fR otherwise if unambiguous\N'46'
.SH COMMANDS
.P
Without argument, defaults to \fBlist\fR\N'46'
.TP 4
\fBlist\fR 
Lists pinned packages\N'46'
.TP 4
\fBadd\fR \fIPACKAGE\fR \fITARGET\fR
Pins package \fIPACKAGE\fR to \fITARGET\fR, which may be a version, a path, or a URL\N'46' \fIPACKAGE\fR can be omitted if \fITARGET\fR contains one or more package descriptions\N'46' \fITARGET\fR can be replaced by \fB\N'45'\N'45'dev\N'45'repo\fR if a package by that name is already known\N'46' If \fITARGET\fR is \fB\N'45'\fR, the package is pinned as a virtual package, without any source\N'46' opam will infer the kind of pinning from the format (and contents, if local) of \fITARGET\fR, Use \fB\N'45'\N'45'kind\fR or an explicit URL to disable that behaviour\N'46' Pins to version control systems may target a specific branch or commit using \fB#branch\fR e\N'46'g\N'46' \fBgit://host/me/pkg#testing\fR\N'46' If \fIPACKAGE\fR is not a known package name, a new package by that name will be locally created\N'46' For source pinnings, the package version may be specified by using the format \fINAME\fR\N'46'\fIVERSION\fR for \fIPACKAGE\fR, in the source opam file, or with \fBedit\fR\N'46'
.TP 4
\fBremove\fR \fINAMES\N'46'\N'46'\N'46'|TARGET\fR
Unpins packages \fINAMES\fR, restoring their definition from the repository, if any\N'46' With a \fITARGET\fR, unpins everything that is currently pinned to that target\N'46'
.TP 4
\fBedit\fR \fINAME\fR
Opens an editor giving you the opportunity to change the package definition that opam will locally use for package \fINAME\fR, including its version and source URL\N'46' Using the format \fINAME\N'46'VERSION\fR will update the version in the opam file in advance of editing, without changing the actual target\N'46' The chosen editor is determined from environment variables \fBOPAM_EDITOR\fR, \fBVISUAL\fR or \fBEDITOR\fR, in order\N'46'
.SH OPTIONS
.TP 4
\fB\N'45'\N'45'dev\N'45'repo\fR

.TP 4
\fB\N'45'e\fR, \fB\N'45'\N'45'edit\fR
With \fIopam pin add\fR, edit the opam file as with `opam pin edit\N'39' after pinning\N'46'
.TP 4
\fB\N'45'j\fR \fIJOBS\fR, \fB\N'45'\N'45'jobs\fR=\fIJOBS\fR
Set the maximal number of concurrent jobs to use\N'46' The default value is calculated from the number of cores\N'46' You can also set it using the \fB$OPAMJOBS\fR environment variable\N'46'
.TP 4
\fB\N'45'k\fR \fIKIND\fR, \fB\N'45'\N'45'kind\fR=\fIKIND\fR
Sets the kind of pinning\N'46' Must be one of one of `version\N'39', `path\N'39', `http\N'39', `git\N'39', `darcs\N'39', `hg\N'39', `none\N'39' or `auto\N'39'\N'46' If unset or \fIauto\fR, is inferred from the format of the target, defaulting to the appropriate version control if one is detected in the given directory, or to \fIpath\fR otherwise\N'46' \fIOPAMPINKINDAUTO\fR can be set to "0" to disable automatic detection of version control\N'46'Use \fInone\fR to pin without a target (for virtual packages)\N'46'
.TP 4
\fB\N'45'n\fR, \fB\N'45'\N'45'no\N'45'action\fR
Just record the new pinning status, and don\N'39't prompt for (re)installation or removal of affected packages\N'46'
.TP 4
\fB\N'45's\fR, \fB\N'45'\N'45'short\fR
Output raw lists of names, one per line, skipping any details\N'46'
.SH PACKAGE BUILD OPTIONS
.TP 4
\fB\N'45'b\fR, \fB\N'45'\N'45'keep\N'45'build\N'45'dir\fR
Keep the build directories after compiling packages\N'46' This is equivalent to setting \fB$OPAMKEEPBUILDDIR\fR to "true"\N'46'
.TP 4
\fB\N'45'd\fR, \fB\N'45'\N'45'with\N'45'doc\fR, \fB\N'45'\N'45'build\N'45'doc\fR
Build the package documentation\N'46' This only affects packages listed on the command\N'45'line\N'46' The \fB\N'45'\N'45'build\N'45'doc\fR form is deprecated as this does also installation\N'46' This is equivalent to setting \fB$OPAMWITHDOC\fR (or the deprecated \fB$OPAMBUILDDOC\fR) to "true"\N'46'
.TP 4
\fB\N'45'\N'45'dry\N'45'run\fR
Simulate the command, but don\N'39't actually perform any changes\N'46'
.TP 4
\fB\N'45'\N'45'fake\fR
This option registers the actions into the opam database, without actually performing them\N'46' WARNING: This option is dangerous and likely to break your opam environment\N'46' You probably want `\N'45'\N'45'dry\N'45'run\N'39'\N'46' You\N'39've been warned\N'46'
.TP 4
\fB\N'45'\N'45'ignore\N'45'constraints\N'45'on\fR[=\fIPACKAGES\fR] (default=)
Forces opam to ignore version constraints on all dependencies to the listed packages\N'46' This can be used to test compatibility, but expect builds to break when using this\N'46' Note that version constraints on optional dependencies and conflicts are unaffected\N'46'
.TP 4
\fB\N'45'\N'45'inplace\N'45'build\fR
When compiling a package which has its source bound to a local directory, process the build and install actions directly in that directory, rather than in a clean copy handled by opam\N'46' This only affects packages that are explicitly listed on the command\N'45'line\N'46' This is equivalent to setting \fB$OPAMINPLACEBUILD\fR to "true"\N'46'
.TP 4
\fB\N'45'\N'45'locked\fR[=\fISUFFIX\fR] (default=locked)
In commands that use opam files found from pinned sources, if a variant of the file with an added \N'46'\fISUFFIX\fR extension is found (e\N'46'g\N'46' \fBfoo\N'46'opam\N'46'locked\fR besides \fBfoo\N'46'opam\fR), that will be used instead\N'46' This is typically useful to offer a more specific set of dependencies and reproduce similar build contexts, hence the name\N'46' The \fIopam lock\fR plugin can be used to generate such files, based on the versions of the dependencies currently installed on the host\N'46' This is equivalent to setting the \fB$OPAMLOCK\fR environment variable\N'46' Note that this option doesn\N'39't generally affect already pinned packages\N'46'
.TP 4
\fB\N'45'm\fR \fIMAKE\fR, \fB\N'45'\N'45'make\fR=\fIMAKE\fR
Use \fIMAKE\fR as the default \N'39'make\N'39' command\N'46' Deprecated: use \fBopam config set[\N'45'global] make MAKE\fR instead\N'46' Has no effect if the \fImake\fR variable is defined\N'46'
.TP 4
\fB\N'45'\N'45'no\N'45'checksums\fR
Do not verify the checksum of downloaded archives\N'46'This is equivalent to setting \fB$OPAMNOCHECKSUMS\fR to "true"\N'46'
.TP 4
\fB\N'45'\N'45'require\N'45'checksums\fR
Reject the installation of packages that don\N'39't provide a checksum for the upstream archives\N'46' This is equivalent to setting \fB$OPAMREQUIRECHECKSUMS\fR to "true"\N'46'
.TP 4
\fB\N'45'\N'45'reuse\N'45'build\N'45'dir\fR
Reuse existing build directories (kept by using \fB\N'45'\N'45'keep\N'45'build\N'45'dir\fR), instead of compiling from a fresh clone of the source\N'46' This can be faster, but also lead to failures if the build systems of the packages don\N'39't handle upgrades of dependencies well\N'46' This is equivalent to setting \fB$OPAMREUSEBUILDDIR\fR to "true"\N'46'
.TP 4
\fB\N'45'\N'45'show\N'45'actions\fR
Call the solver and display the actions\N'46' Don\N'39't perform any changes\N'46'
.TP 4
\fB\N'45'\N'45'skip\N'45'updates\fR
When running an install, upgrade or reinstall on source\N'45'pinned packages, they are normally updated from their origin first\N'46' This flag disables that behaviour and will keep them to their version in cache\N'46'
.TP 4
\fB\N'45't\fR, \fB\N'45'\N'45'with\N'45'test\fR, \fB\N'45'\N'45'build\N'45'test\fR
Build and \fBrun\fR the package unit\N'45'tests\N'46' This only affects packages listed on the command\N'45'line\N'46' The \fB\N'45'\N'45'build\N'45'test\fR form is deprecated as this also affects installation\N'46' This is equivalent to setting \fB$OPAMWITHTEST\fR (or the deprecated \fB$OPAMBUILDTEST\fR) to "true"\N'46'
.TP 4
\fB\N'45'\N'45'unlock\N'45'base\fR
Allow changes to the packages set as switch base (typically, the main compiler)\N'46' Use with caution\N'46'

.TP 4
\fB\N'45'\N'45'best\N'45'effort\fR
Don\N'39't fail if all requested packages can\N'39't be installed: try to install as many as possible\N'46' Note that not all external solvers may support this option (recent versions of \fIaspcud\fR or \fImccs\fR should)\N'46'
.TP 4
\fB\N'45'\N'45'color\fR=\fIWHEN\fR
Colorize the output\N'46' \fIWHEN\fR must be one of `always\N'39', `never\N'39' or `auto\N'39'\N'46'
.TP 4
\fB\N'45'\N'45'criteria\fR=\fICRITERIA\fR
Specify user \fIpreferences\fR for dependency solving for this run\N'46' Overrides both \fB$OPAMCRITERIA\fR and \fB$OPAMUPGRADECRITERIA\fR\N'46' For details on the supported language, and the external solvers available, see \fI http://opam\N'46'ocaml\N'46'org/doc/Specifying_Solver_Preferences\N'46'html\fR\N'46' A general guide to using solver preferences can be found at \fI http://www\N'46'dicosmo\N'46'org/Articles/usercriteria\N'46'pdf\fR\N'46'
.TP 4
\fB\N'45'\N'45'cudf\fR=\fIFILENAME\fR
Debug option: Save the CUDF requests sent to the solver to \fIFILENAME\fR\N'45'<n>\N'46'cudf\N'46'
.TP 4
\fB\N'45'\N'45'debug\fR
Print debug message to stderr\N'46' This is equivalent to setting \fB$OPAMDEBUG\fR to "true"\N'46'
.TP 4
\fB\N'45'\N'45'debug\N'45'level\fR=\fILEVEL\fR
Like \fB\N'45'\N'45'debug\fR, but allows specifying the debug level (\fB\N'45'\N'45'debug\fR sets it to 1)\N'46' Equivalent to setting \fB$OPAMDEBUG\fR to a positive integer\N'46'
.TP 4
\fB\N'45'\N'45'git\N'45'version\fR
Print the git version of opam, if set (i\N'46'e\N'46' you are using a development version), and exit\N'46'
.TP 4
\fB\N'45'\N'45'help\fR[=\fIFMT\fR] (default=auto)
Show this help in format \fIFMT\fR\N'46' The value \fIFMT\fR must be one of `auto\N'39', `pager\N'39', `groff\N'39' or `plain\N'39'\N'46' With `auto\N'39', the format is `pager` or `plain\N'39' whenever the \fBTERM\fR env var is `dumb\N'39' or undefined\N'46'
.TP 4
\fB\N'45'\N'45'ignore\N'45'pin\N'45'depends\fR
Ignore extra pins required by packages that get pinned, either manually through \fIopam pin\fR or through \fIopam install DIR\fR\N'46' This is equivalent to setting \fBIGNOREPINDEPENDS=true\fR\N'46'
.TP 4
\fB\N'45'\N'45'json\fR=\fIFILENAME\fR
Save the results of the opam run in a computer\N'45'readable file\N'46' If the filename contains the character `%\N'39', it will be replaced by an index that doesn\N'39't overwrite an existing file\N'46' Similar to setting the \fB$OPAMJSON\fR variable\N'46'
.TP 4
\fB\N'45'\N'45'no\N'45'auto\N'45'upgrade\fR
When configuring or updating a repository that is written for an earlier opam version (1\N'46'2), opam internally converts it to the current format\N'46' This disables this behaviour\N'46' Note that repositories should define their format version in a \N'39'repo\N'39' file at their root, or they will be assumed to be in the older format\N'46' It is, in any case, preferable to upgrade the repositories manually using \fIopam admin upgrade [\N'45'\N'45'mirror URL]\fR when possible\N'46'
.TP 4
\fB\N'45'\N'45'no\N'45'self\N'45'upgrade\fR
Opam will replace itself with a newer binary found at \fBOPAMROOT/opam\fR if present\N'46' This disables this behaviour\N'46'

.TP 4
\fB\N'45'\N'45'safe\fR, \fB\N'45'\N'45'readonly\fR
Make sure nothing will be automatically updated or rewritten\N'46' Useful for calling from completion scripts, for example\N'46' Will fail whenever such an operation is needed ; also avoids waiting for locks, skips interactive questions and overrides the \fB$OPAMDEBUG\fR variable\N'46'
.TP 4
\fB\N'45'\N'45'solver\fR=\fICMD\fR
Specify the CUDF solver to use for resolving package installation problems\N'46' This is either a predefined solver (this version of opam supports builtin\N'45'dummy\N'45'solver, aspcud, mccs, aspcud\N'45'old, packup), or a custom command that should contain the variables %{input}%, %{output}%, %{criteria}%, and optionally %{timeout}%\N'46'
.TP 4
\fB\N'45'\N'45'strict\fR
Fail whenever an error is found in a package definition or a configuration file\N'46' The default is to continue silently if possible\N'46'
.TP 4
\fB\N'45'\N'45'switch\fR=\fISWITCH\fR
Use \fISWITCH\fR as the current compiler switch\N'46' This is equivalent to setting \fB$OPAMSWITCH\fR to \fISWITCH\fR\N'46'
.TP 4
\fB\N'45'\N'45'use\N'45'internal\N'45'solver\fR, \fB\N'45'\N'45'no\N'45'aspcud\fR
Disable any external solver, and use the built\N'45'in one (this requires that opam has been compiled with a built\N'45'in solver)\N'46'
.TP 4
\fB\N'45'v\fR, \fB\N'45'\N'45'verbose\fR
Be more verbose\N'46' One \fB\N'45'v\fR shows all package commands, repeat to also display commands called internally (e\N'46'g\N'46' \fItar\fR, \fIcurl\fR, \fIpatch\fR etc\N'46') Repeating \fIn\fR times is equivalent to setting \fB$OPAMVERBOSE\fR to "\fIn\fR"\N'46'
.TP 4
\fB\N'45'\N'45'version\fR
Show version information\N'46'
.TP 4
\fB\N'45'w\fR, \fB\N'45'\N'45'working\N'45'dir\fR
Whenever updating packages that are bound to a local, version\N'45'controlled directory, update to the current working state of their source instead of the last committed state, or the ref they are pointing to\N'46' This only affects packages explicitly listed on the command\N'45'line\N'46'
.TP 4
\fB\N'45'y\fR, \fB\N'45'\N'45'yes\fR
Answer yes to all yes/no questions without prompting\N'46' This is equivalent to setting \fB$OPAMYES\fR to "true"\N'46'
