.SH NAME
.P
opam\N'45'init \N'45' Initialize opam state, or set init options\N'46'
.SH SYNOPSIS
.P
\fBopam init\fR [\fIOPTION\fR]\N'46'\N'46'\N'46' [\fINAME\fR] [\fIADDRESS\fR]
.SH DESCRIPTION
.P
Initialise the opam state, or update opam init options
.P
The \fBinit\fR command initialises a local "opam root" (by default, \fI~/\N'46'opam/\fR) that holds opam\N'39's data and packages\N'46' This is a necessary step for normal operation of opam\N'46' The initial software repositories are fetched, and an initial \N'39'switch\N'39' can also be installed, according to the configuration and options\N'46' These can be afterwards configured using \fBopam switch\fR and \fBopam repository\fR\N'46'
.P
The initial repository and defaults can be set through a configuration file found at \fI~/\N'46'opamrc\fR or \fI/etc/opamrc\fR\N'46'
.P
Additionally, this command allows to customise some aspects of opam\N'39's shell integration, when run initially (avoiding the interactive dialog), but also at any later time\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

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'
.SH COMMON OPTIONS
.P

.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'

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

.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

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
