PROGRAM:

NAME

opam-uninstall - An alias for remove.

SYNOPSIS

opam uninstall [OPTION]... [PACKAGES]...

DESCRIPTION

opam uninstall is an alias for opam remove.

See opam remove --help for details.

ARGUMENTS

PACKAGES
List of package names, with an optional version or constraint, e.g `pkg', `pkg.1.0' or
`pkg>=0.5'.

COMMON OPTIONS

--color=WHEN (absent=auto)
Colorize the output. WHEN must be one of `always', `never' or `auto'.

--criteria=CRITERIA
Specify user preferences for dependency solving for this run. Overrides both
$OPAMCRITERIA and $OPAMUPGRADECRITERIA. For details on the supported language, and the
external solvers available, see
http://opam.ocaml.org/doc/Specifying_Solver_Preferences.html. A general guide to using
solver preferences can be found at http://www.dicosmo.org/Articles/usercriteria.pdf.
The default value is
-count(down),-count(removed),-notuptodate(solution),-sum(solution,version-lag),-count(new)
for upgrades, and
-count(removed),-notuptodate(request),-sum(request,version-lag),-count(down),-notuptodate(changed),-count(changed),-notuptodate(solution),-sum(solution,version-lag)
otherwise.

--cudf=FILENAME
Debug option: Save the CUDF requests sent to the solver to FILENAME-<n>.cudf.

--debug
Print debug message to stderr. This is equivalent to setting $OPAMDEBUG to "true".

--debug-level=LEVEL
Like `--debug', but allows specifying the debug level (`--debug' sets it to 1).
Equivalent to setting $OPAMDEBUG to a positive integer.

--git-version
Print the git version if it exists and exit.

--no-base-packages
Do not install base packages (useful for testing purposes). This is equivalent to
setting $OPAMNOBASEPACKAGES to a non-empty string.

--no-self-upgrade
OPAM will replace itself with a newer binary found at OPAMROOT/opam if present. This
disables this behaviour.

-q, --quiet
Be quiet when installing a new compiler.

--root=ROOT (absent=~/.opam)
Use ROOT as the current root path. This is equivalent to setting $OPAMROOT to ROOT.

--safe
Make sure nothing will be automatically updated or rewritten. Useful for calling from
completion scripts, for example. Will fail whenever such an operation is needed ; also
avoids waiting for locks, skips interactive questions and overrides the OPAMDEBUG
variable.

--solver=CMD
Specify the name of the external dependency solver. The default value is aspcud.
Either 'aspcud', 'packup' or a custom command that may contain the variables
%{input}%, %{output}% and %{criteria}%

--strict
Fail whenever an error is found in a package definition or a configuration file. The
default is to continue silently if possible.

--switch=SWITCH
Use SWITCH as the current compiler switch. This is equivalent to setting $OPAMSWITCH
to SWITCH.

--use-internal-solver, --no-aspcud
Force use of internal heuristics, even if an external solver is available.

-v, --verbose
Be more verbose, show package sub-commands and their output. Repeat to see more.
Repeating n times is equivalent to setting $OPAMVERBOSE to "n".

-y, --yes
Disable interactive mode and answer yes to all questions that would otherwise be asked
to the user. This is equivalent to setting $OPAMYES to "true".

OPTIONS

-a, --auto-remove
Remove all the packages which have not been explicitly installed and which are not
necessary anymore. It is possible to prevent the removal of an already-installed
package by running opam install <pkg>. This flag can also be set using the
$OPAMAUTOREMOVE configuration variable.

-b, --keep-build-dir
Keep the build directory. This is equivalent to setting $OPAMKEEPBUILDDIR to "true".

-d, --build-doc
Build the package documentation. This is equivalent to setting $OPAMBUILDDOC to
"true".

--dry-run
Simulate the command, but don't actually perform any changes.

-e TAGS, --external=TAGS
Display the external packages associated to the given tags. This is deprecated, use
`opam list --external' instead

--fake
This option registers the actions into the OPAM database, without actually performing
them. WARNING: This option is dangerous and likely to break your OPAM environment. You
probably want `--dry-run'. You've been warned.

--force
Execute the remove commands of given packages directly, even if they are not
considered installed by OPAM.

--help[=FMT] (default=pager)
Show this help in format FMT (pager, plain or groff).

-j JOBS, --jobs=JOBS
Set the maximal number of concurrent jobs to use. You can also set it using the
$OPAMJOBS environment variable.

--json=FILENAME
Save the result output of an OPAM run in a computer-readable file

-m MAKE, --make=MAKE
Use MAKE as the default 'make' command.

--no-checksums
Do not verify the checksum of downloaded archives.This is equivalent to setting
$OPAMNOCHECKSUMS to "true".

--require-checksums
Reject the installation of packages that don't provide a checksum for the upstream
archives. This is equivalent to setting $OPAMREQUIRECHECKSUMS to "true".

--show-actions
Call the solver and display the actions. Don't perform any changes.

-t, --build-test
Build and run the package unit-tests. This is equivalent to setting $OPAMBUILDTEST to
"true".

--version
Show version information.
