1OPAM ADMIN-LINT(1) Opam admin Manual OPAM ADMIN-LINT(1)
2
6 opam admin-lint - Runs 'opam lint' and reports on a whole repository
7
9 opam admin lint [OPTION]... [INT]...
10
12 This command gathers linting results on all files in a repository. The
13 warnings and errors to show or hide can be selected
14
16 INT Show only these warnings
17
19 -i INT, --ignore-packages=INT
20 Ignore any packages having one of these warnings or errors
21 -l, --list
23 Only list package names, without warning details
24 -s, --short
26 Print only packages and warning/error numbers, without explanations
27 -W, --warn-error
29 Return failure on any warnings, not only on errors
30 -x INT, --exclude=INT
32 Exclude the given warnings or errors
33
35 These options are common to all commands.
36 --best-effort
38 Don't fail if all requested packages can't be installed: try to
39 install as many as possible. Note that not all external solvers may
40 support this option (recent versions of aspcud or mccs should).
41 This is equivalent to setting $OPAMBESTEFFORT environment variable.
42 --color=WHEN
44 Colorize the output. WHEN must be one of `always', `never' or
45 `auto'.
46 --criteria=CRITERIA
48 Specify user preferences for dependency solving for this run.
49 Overrides both $OPAMCRITERIA and $OPAMUPGRADECRITERIA. For details
50 on the supported language, and the external solvers available, see
51 http://opam.ocaml.org/doc/External_solvers.html. A general guide to
52 using solver preferences can be found at
53 http://www.dicosmo.org/Articles/usercriteria.pdf.
54 --cudf=FILENAME
56 Debug option: Save the CUDF requests sent to the solver to
57 FILENAME-<n>.cudf.
58 --debug
60 Print debug message to stderr. This is equivalent to setting
61 $OPAMDEBUG to "true".
62 --debug-level=LEVEL
64 Like --debug, but allows specifying the debug level (--debug sets
65 it to 1). Equivalent to setting $OPAMDEBUG to a positive integer.
66 --git-version
68 Print the git version of opam, if set (i.e. you are using a
69 development version), and exit.
70 --help[=FMT] (default=auto)
72 Show this help in format FMT. The value FMT must be one of `auto',
73 `pager', `groff' or `plain'. With `auto', the format is `pager` or
74 `plain' whenever the TERM env var is `dumb' or undefined.
75 --ignore-pin-depends
77 Ignore extra pins required by packages that get pinned, either
78 manually through opam pin or through opam install DIR. This is
79 equivalent to setting IGNOREPINDEPENDS=true.
80 --json=FILENAME
82 Save the results of the opam run in a computer-readable file. If
83 the filename contains the character `%', it will be replaced by an
84 index that doesn't overwrite an existing file. Similar to setting
85 the $OPAMJSON variable.
86 --no-aspcud
88 Deprecated.
89 --no-auto-upgrade
91 When configuring or updating a repository that is written for an
92 earlier opam version (1.2), opam internally converts it to the
93 current format. This disables this behaviour. Note that
94 repositories should define their format version in a 'repo' file at
95 their root, or they will be assumed to be in the older format. It
96 is, in any case, preferable to upgrade the repositories manually
97 using opam admin upgrade [--mirror URL] when possible.
98 -q, --quiet
100 Disables --verbose.
101 --root=ROOT
103 Use ROOT as the current root path. This is equivalent to setting
104 $OPAMROOT to ROOT.
105 --safe, --readonly
107 Make sure nothing will be automatically updated or rewritten.
108 Useful for calling from completion scripts, for example. Will fail
109 whenever such an operation is needed ; also avoids waiting for
110 locks, skips interactive questions and overrides the $OPAMDEBUG
111 variable. This is equivalent to set environment variable $OPAMSAFE.
112 --solver=CMD
114 Specify the CUDF solver to use for resolving package installation
115 problems. This is either a predefined solver (this version of opam
116 supports builtin-mccs+lp(), builtin-mccs+glpk, aspcud, mccs,
117 aspcud-old, packup), or a custom command that should contain the
118 variables %{input}%, %{output}%, %{criteria}%, and optionally
119 %{timeout}%. This is equivalent to setting $OPAMEXTERNALSOLVER.
120 --strict
122 Fail whenever an error is found in a package definition or a
123 configuration file. The default is to continue silently if
124 possible.
125 --switch=SWITCH
127 Use SWITCH as the current compiler switch. This is equivalent to
128 setting $OPAMSWITCH to SWITCH.
129 --use-internal-solver
131 Disable any external solver, and use the built-in one (this
132 requires that opam has been compiled with a built-in solver). This
133 is equivalent to setting $OPAMNOASPCUD or $OPAMUSEINTERNALSOLVER.
134 -v, --verbose
136 Be more verbose. One -v shows all package commands, repeat to also
137 display commands called internally (e.g. tar, curl, patch etc.)
138 Repeating n times is equivalent to setting $OPAMVERBOSE to "n".
139 --version
141 Show version information.
142 -w, --working-dir
144 Whenever updating packages that are bound to a local,
145 version-controlled directory, update to the current working state
146 of their source instead of the last committed state, or the ref
147 they are pointing to. This only affects packages explicitly listed
148 on the command-line.It can also be set with $OPAMWORKINGDIR.
149 -y, --yes
151 Answer yes to all yes/no questions without prompting. This is
152 equivalent to setting $OPAMYES to "true".
153
155 Opam makes use of the environment variables listed here. Boolean
156 variables should be set to "0", "no", "false" or the empty string to
157 disable, "1", "yes" or "true" to enable.
158 OPAMALLPARENS surround all filters with parenthesis
160 OPAMAUTOREMOVE see remove option `--auto-remove`
162 OPAMBESTEFFORT see option `--best-effort`
164 OPAMBESTEFFORTPREFIXCRITERIA sets the string that must be prepended to
166 the criteria when the `--best-effort` option is set, and is expected to
167 maximise the `opam-query` property in the solution
168 OPAMCOLOR, when set to always or never, sets a default value for the
170 --color option.
171 OPAMCRITERIA specifies user preferences for dependency solving. The
173 default value depends on the solver version, use `config report` to
174 know the current setting. See also option --criteria
175 OPAMCUDFFILE file save the cudf graph to file-actions-explicit.dot
177 OPAMCURL can be used to select a given 'curl' program. See OPAMFETCH
179 for more options.
180 OPAMDEBUG see options `--debug' and `--debug-level'.
182 OPAMDOWNLOADJOBS sets the maximum number of simultaneous downloads.
184 OPAMDRYRUN see option `--dry-run`
186 OPAMEDITOR sets the editor to use for opam file editing, overrides
188 $EDITOR and $VISUAL
189 OPAMERRLOGLEN sets the number of log lines printed when a sub-process
191 fails. 0 to print all.
192 OPAMEXTERNALSOLVER see option `--solver'.
194 OPAMFAKE see option `--fake`
196 OPAMFETCH specifies how to download files: either `wget', `curl' or a
198 custom command where variables %{url}%, %{out}%, %{retry}%,
199 %{compress}% and %{checksum}% will be replaced. Overrides the
200 'download-command' value from the main config file.
201 OPAMFIXUPCRITERIA same as OPAMUPGRADECRITERIA, but specific to fixup
203 OPAMIGNORECONSTRAINTS see install option `--ignore-constraints-on`
205 OPAMIGNOREPINDEPENDS see option `--ignore-pin-depends`
207 OPAMJOBS sets the maximum number of parallel workers to run.
209 OPAMJSON log json output to the given file (use character `%' to index
211 the files)
212 OPAMLOCKED see install option `--locked`
214 OPAMLOGS logdir sets log directory, default is a temporary directory in
216 /tmp
217 OPAMMAKECMD set the system make command to use
219 OPAMNOAUTOUPGRADE disables automatic internal upgrade of repositories
221 in an earlier format to the current one, on 'update' or 'init'.
222 OPAMKEEPLOGS tells opam to not remove some temporary command logs and
224 some backups. This skips some finalisers and may also help to get more
225 reliable backtraces
226 OPAMLOCKRETRIES sets the number of tries after which opam gives up
228 acquiring its lock and fails. <= 0 means infinite wait.
229 OPAMMERGEOUT merge process outputs, stderr on stdout
231 OPAMNO answer no to any question asked.
233 OPAMNOASPCUD Deprecated.
235 OPAMNOCHECKSUMS enables option --no-checksums when available.
237 OPAMNOSELFUPGRADE see option `--no-self-upgrade'.
239 OPAMPINKINDAUTO sets whether version control systems should be detected
241 when pinning to a local path. Enabled by default since 1.3.0.
242 OPAMPRECISETRACKING fine grain tracking of directories
244 OPAMREQUIRECHECKSUMS Enables option `--require-checksums' when
246 available (e.g. for `opam install`).
247 OPAMRETRES sets the number of tries before failing downloads.
249 OPAMROOT see option `--root'. This is automatically set by `opam env
251 --root=DIR --set-root'.
252 OPAMROOTISOK don't complain when running as root.
254 OPAMSAFE see option `--safe'
256 OPAMSHOW see option `--show`
258 OPAMSKIPUPDATE see option `--skip-updates`
260 OPAMSKIPVERSIONCHECKS bypasses some version checks. Unsafe, for
262 compatibility testing only.
263 OPAMSOLVERTIMEOUT change the time allowance of the solver. Default is
265 60.0, set to 0 for unlimited. Note that all solvers may not support
266 this option.
267 OPAMSTATUSLINE display a dynamic status line showing what's currently
269 going on on the terminal. (one of one of `always', `never' or `auto')
270 OPAMSTATS display stats at the end of command
272 OPAMSTRICT fail on inconsistencies (file reading, switch import, etc.)
274 OPAMSWITCH see option `--switch'. Automatically set by `opam env
276 --switch=SWITCH --set-switch'.
277 OPAMUNLOCKBASE see install option `--unlock-base`
279 OPAMUPGRADECRITERIA specifies user preferences for dependency solving
281 when performing an upgrade. Overrides OPAMCRITERIA in upgrades if both
282 are set. See also option --criteria
283 OPAMUSEINTERNALSOLVER see option `--use-internal-solver'.
285 OPAMUSEOPENSSL force openssl use for hash computing
287 OPAMUTF8 use UTF8 characters in output (one of one of `always', `never'
289 or `auto'). By default `auto', which is determined from the locale).
290 OPAMUTF8MSGS use extended UTF8 characters (camels) in opam messages.
292 Implies OPAMUTF8. This is set by default on OSX only.
293 OPAMVALIDATIONHOOK hook if set, uses the `%{hook%}` command to validate
295 an opam repository update
296 OPAMVAR_var overrides the contents of the variable var when
298 substituting `%{var}%` strings in `opam` files.
299 OPAMVAR_package_var overrides the contents of the variable package:var
301 when substituting `%{package:var}%` strings in `opam` files.
302 OPAMVERBOSE see option `--verbose'.
304 OPAMWORKINGDIR see option `--working-dir`
306 OPAMYES see option `--yes'.
308
310 As an exception to the following, the `exec' command returns 127 if the
311 command was not found or couldn't be executed, and the command's exit
312 value otherwise.
313 0 Success, or true for boolean queries.
315 1 False. Returned when a boolean return value is expected, e.g. when
317 running with --check, or for queries like opam lint.
318 2 Bad command-line arguments, or command-line arguments pointing to
320 an invalid context (e.g. file not following the expected format).
321 5 Not found. You requested something (package, version, repository,
323 etc.) that couldn't be found.
324 10 Aborted. The operation required confirmation, which wasn't given.
326 15 Could not acquire the locks required for the operation.
328 20 There is no solution to the user request. This can be caused by
330 asking to install two incompatible packages, for example.
331 30 Error in package definition, or other metadata files. Using
333 --strict raises this error more often.
334 31 Package script error. Some package operations were unsuccessful.
336 This may be an error in the packages or an incompatibility with
337 your system. This can be a partial error.
338 40 Sync error. Could not fetch some remotes from the network. This can
340 be a partial error.
341 50 Configuration error. Opam or system configuration doesn't allow
343 operation, and needs fixing.
344 60 Solver failure. The solver failed to return a sound answer. It can
346 be due to a broken external solver, or an error in solver
347 configuration.
348 99 Internal error. Something went wrong, likely due to a bug in opam
350 itself.
351 130 User interrupt. SIGINT was received, generally due to the user
353 pressing Ctrl-C.
