opam info [OPTION]... PACKAGES...

opam info is an alias for opam show.

See opam show --help for details.

PACKAGES

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

--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".

-f FIELDS, --field=FIELDS

Only display these fields. You can specify multiple fields by separating them with commas.

--help[=FMT] (default=pager)

Show this help in format FMT (pager, plain or groff).

--raw

Print the raw opam file for this package

--version

Show version information.

--where

Print the location of the opam file used for this package
