NAME

       opam admin-lint - Runs 'opam lint' and reports on a whole repository

SYNOPSIS

       opam admin lint [OPTION]... [INT]...

DESCRIPTION

       This command gathers linting results on all files in a repository. The warnings and errors to show or
       hide can be selected

ARGUMENTS

       INT Show only these warnings

OPTIONS

       -i INT, --ignore-packages=INT
           Ignore any packages having one of these warnings or errors

       -l, --list
           Only list package names, without warning details

       -s, --short
           Print only packages and warning/error numbers, without explanations

       -W, --warn-error
           Return failure on any warnings, not only on errors

       -x INT, --exclude=INT
           Exclude the given warnings or errors

COMMON OPTIONS

These options are common to all commands.

--best-effort
Don't fail if all requested packages can't be installed: try to install as many as possible. Note
that not all external solvers may support this option (recent versions of aspcud or mccs should).
This is equivalent to setting $OPAMBESTEFFORT environment variable.

--color=WHEN
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/External_solvers.html. A general guide to using solver preferences can be
found at http://www.dicosmo.org/Articles/usercriteria.pdf.

--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 of opam, if set (i.e. you are using a development version), and exit.

--help[=FMT] (default=auto)
Show this help in format FMT. The value FMT must be one of `auto', `pager', `groff' or `plain'. With
`auto', the format is `pager` or `plain' whenever the TERM env var is `dumb' or undefined.

--ignore-pin-depends
Ignore extra pins required by packages that get pinned, either manually through opam pin or through
opam install DIR. This is equivalent to setting IGNOREPINDEPENDS=true.

--json=FILENAME
Save the results of the opam run in a computer-readable file. If the filename contains the character
`%', it will be replaced by an index that doesn't overwrite an existing file. Similar to setting the
$OPAMJSON variable.

--no-aspcud
Deprecated.

--no-auto-upgrade
When configuring or updating a repository that is written for an earlier opam version (1.2), opam
internally converts it to the current format. This disables this behaviour. Note that repositories
should define their format version in a 'repo' file at their root, or they will be assumed to be in
the older format. It is, in any case, preferable to upgrade the repositories manually using opam
admin upgrade [--mirror URL] when possible.

-q, --quiet
Disables --verbose.

--root=ROOT
Use ROOT as the current root path. This is equivalent to setting $OPAMROOT to ROOT.

--safe, --readonly
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. This is equivalent to set
environment variable $OPAMSAFE.

--solver=CMD
Specify the CUDF solver to use for resolving package installation problems. This is either a
predefined solver (this version of opam supports builtin-mccs+lp(), builtin-mccs+glpk, aspcud, mccs,
aspcud-old, packup), or a custom command that should contain the variables %{input}%, %{output}%,
%{criteria}%, and optionally %{timeout}%. This is equivalent to setting $OPAMEXTERNALSOLVER.

--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
Disable any external solver, and use the built-in one (this requires that opam has been compiled with
a built-in solver). This is equivalent to setting $OPAMNOASPCUD or $OPAMUSEINTERNALSOLVER.

-v, --verbose
Be more verbose. One -v shows all package commands, repeat to also display commands called internally
(e.g. tar, curl, patch etc.) Repeating n times is equivalent to setting $OPAMVERBOSE to "n".

--version
Show version information.

-w, --working-dir
Whenever updating packages that are bound to a local, version-controlled directory, update to the
current working state of their source instead of the last committed state, or the ref they are
pointing to. This only affects packages explicitly listed on the command-line.It can also be set with
$OPAMWORKINGDIR.

-y, --yes
Answer yes to all yes/no questions without prompting. This is equivalent to setting $OPAMYES to
"true".

ENVIRONMENT VARIABLES

Opam makes use of the environment variables listed here. Boolean variables should be set to "0", "no",
"false" or the empty string to disable, "1", "yes" or "true" to enable.

OPAMALLPARENS surround all filters with parenthesis

OPAMAUTOREMOVE see remove option `--auto-remove`

OPAMBESTEFFORT see option `--best-effort`

OPAMBESTEFFORTPREFIXCRITERIA sets the string that must be prepended to the criteria when the
`--best-effort` option is set, and is expected to maximise the `opam-query` property in the solution

OPAMCOLOR, when set to always or never, sets a default value for the --color option.

OPAMCRITERIA specifies user preferences for dependency solving. The default value depends on the solver
version, use `config report` to know the current setting. See also option --criteria

OPAMCUDFFILE file save the cudf graph to file-actions-explicit.dot

OPAMCURL can be used to select a given 'curl' program. See OPAMFETCH for more options.

OPAMDEBUG see options `--debug' and `--debug-level'.

OPAMDOWNLOADJOBS sets the maximum number of simultaneous downloads.

OPAMDRYRUN see option `--dry-run`

OPAMEDITOR sets the editor to use for opam file editing, overrides $EDITOR and $VISUAL

OPAMERRLOGLEN sets the number of log lines printed when a sub-process fails. 0 to print all.

OPAMEXTERNALSOLVER see option `--solver'.

OPAMFAKE see option `--fake`

OPAMFETCH specifies how to download files: either `wget', `curl' or a custom command where variables
%{url}%, %{out}%, %{retry}%, %{compress}% and %{checksum}% will be replaced. Overrides the
'download-command' value from the main config file.

OPAMFIXUPCRITERIA same as OPAMUPGRADECRITERIA, but specific to fixup

OPAMIGNORECONSTRAINTS see install option `--ignore-constraints-on`

OPAMIGNOREPINDEPENDS see option `--ignore-pin-depends`

OPAMJOBS sets the maximum number of parallel workers to run.

OPAMJSON log json output to the given file (use character `%' to index the files)

OPAMLOCKED see install option `--locked`

OPAMLOGS logdir sets log directory, default is a temporary directory in /tmp

OPAMMAKECMD set the system make command to use

OPAMNOAUTOUPGRADE disables automatic internal upgrade of repositories in an earlier format to the current
one, on 'update' or 'init'.

OPAMKEEPLOGS tells opam to not remove some temporary command logs and some backups. This skips some
finalisers and may also help to get more reliable backtraces

OPAMLOCKRETRIES sets the number of tries after which opam gives up acquiring its lock and fails. <= 0
means infinite wait.

OPAMMERGEOUT merge process outputs, stderr on stdout

OPAMNO answer no to any question asked.

OPAMNOASPCUD Deprecated.

OPAMNOCHECKSUMS enables option --no-checksums when available.

OPAMNOSELFUPGRADE see option `--no-self-upgrade'.

OPAMPINKINDAUTO sets whether version control systems should be detected when pinning to a local path.
Enabled by default since 1.3.0.

OPAMPRECISETRACKING fine grain tracking of directories

OPAMREQUIRECHECKSUMS Enables option `--require-checksums' when available (e.g. for `opam install`).

OPAMRETRES sets the number of tries before failing downloads.

OPAMROOT see option `--root'. This is automatically set by `opam env --root=DIR --set-root'.

OPAMROOTISOK don't complain when running as root.

OPAMSAFE see option `--safe'

OPAMSHOW see option `--show`

OPAMSKIPUPDATE see option `--skip-updates`

OPAMSKIPVERSIONCHECKS bypasses some version checks. Unsafe, for compatibility testing only.

OPAMSOLVERTIMEOUT change the time allowance of the solver. Default is 60.0, set to 0 for unlimited. Note
that all solvers may not support this option.

OPAMSTATUSLINE display a dynamic status line showing what's currently going on on the terminal. (one of
one of `always', `never' or `auto')

OPAMSTATS display stats at the end of command

OPAMSTRICT fail on inconsistencies (file reading, switch import, etc.)

OPAMSWITCH see option `--switch'. Automatically set by `opam env --switch=SWITCH --set-switch'.

OPAMUNLOCKBASE see install option `--unlock-base`

OPAMUPGRADECRITERIA specifies user preferences for dependency solving when performing an upgrade.
Overrides OPAMCRITERIA in upgrades if both are set. See also option --criteria

OPAMUSEINTERNALSOLVER see option `--use-internal-solver'.

OPAMUSEOPENSSL force openssl use for hash computing

OPAMUTF8 use UTF8 characters in output (one of one of `always', `never' or `auto'). By default `auto',
which is determined from the locale).

OPAMUTF8MSGS use extended UTF8 characters (camels) in opam messages. Implies OPAMUTF8. This is set by
default on OSX only.

OPAMVALIDATIONHOOK hook if set, uses the `%{hook%}` command to validate an opam repository update

OPAMVAR_var overrides the contents of the variable var when substituting `%{var}%` strings in `opam`
files.

OPAMVAR_package_var overrides the contents of the variable package:var when substituting
`%{package:var}%` strings in `opam` files.

OPAMVERBOSE see option `--verbose'.

OPAMWORKINGDIR see option `--working-dir`

OPAMYES see option `--yes'.

EXIT STATUS

       As an exception to the following, the `exec' command returns 127 if the command was not found or couldn't
       be executed, and the command's exit value otherwise.

       0   Success, or true for boolean queries.

       1   False.  Returned  when  a  boolean  return  value is expected, e.g. when running with --check, or for
           queries like opam lint.

       2   Bad command-line arguments, or command-line arguments pointing to an invalid context (e.g.  file  not
           following the expected format).

       5   Not found. You requested something (package, version, repository, etc.) that couldn't be found.

       10  Aborted. The operation required confirmation, which wasn't given.

       15  Could not acquire the locks required for the operation.

       20  There  is  no  solution to the user request. This can be caused by asking to install two incompatible
           packages, for example.

       30  Error in package definition, or other metadata files. Using --strict raises this error more often.

       31  Package script error. Some package operations were unsuccessful. This may be an error in the packages
           or an incompatibility with your system. This can be a partial error.

       40  Sync error. Could not fetch some remotes from the network. This can be a partial error.

       50  Configuration error. Opam or system configuration doesn't allow operation, and needs fixing.

       60  Solver failure. The solver failed to return a sound answer. It  can  be  due  to  a  broken  external
           solver, or an error in solver configuration.

       99  Internal error. Something went wrong, likely due to a bug in opam itself.

       130 User interrupt. SIGINT was received, generally due to the user pressing Ctrl-C.
