10
12 opam remote is an alias for opam repository.
13 See opam repository --help for details.
15
17 -a, --all-switches
18 Act on the selections of all configured switches
19 --dont-select
21 Don't update any selections
22 --on-switches=SWITCHES
24 Act on the selections of the given list of switches
25 --set-default
27 Act on the default repository selection that is used for newly
28 created switches
29 --this-switch
31 Act on the selections for the current switch (this is the default)
32
34 -k KIND, --kind=KIND
35 Specify the kind of the repository to be used (one of http, local,
36 git, darcs or hg).
37 --no
39 Answer no to all opam yes/no questions without prompting. See also
40 --confirm-level. This is equivalent to setting $OPAMNO to "true".
41 --rank=RANK (absent=1)
43 Set the rank of the repository in the list of configured
44 repositories. Package definitions are looked in the repositories in
45 increasing rank order, therefore 1 is the highest priority.
46 Negative ints can be used to select from the lowest priority, -1
47 being last. set-repos can otherwise be used to explicitly set the
48 repository list at once.
49 -s, --short
51 Output raw lists of names, one per line, skipping any details.
52 -y, --yes
54 Answer yes to all opam yes/no questions without prompting. See also
55 --confirm-level. This is equivalent to setting $OPAMYES to "true".
56
58 These options are common to all commands.
59 --best-effort
61 Don't fail if all requested packages can't be installed: try to
62 install as many as possible. Note that not all external solvers may
63 support this option (recent versions of aspcud or mccs should).
64 This is equivalent to setting $OPAMBESTEFFORT environment variable.
65 --cli=MAJOR.MINOR (absent=2.1)
67 Use the command-line interface syntax and semantics of MAJOR.MINOR.
68 Intended for any persistent use of opam (scripts, blog posts,
69 etc.), any version of opam in the same MAJOR series will behave as
70 for the specified MINOR release. The flag was not available in opam
71 2.0, so to select the 2.0 CLI, set the OPAMCLI environment variable
72 to 2.0 instead of using this parameter.
73 --color=WHEN
75 Colorize the output. WHEN must be one of always, never or auto.
76 --confirm-level=LEVEL
78 Confirmation level, LEVEL must be one of ask, no, yes or
79 unsafe-yes. Can be specified more than once. If --yes or --no are
80 also given, the value of the last --confirm-level is taken into
81 account. This is equivalent to setting $OPAMCONFIRMLEVEL`.
82 --criteria=CRITERIA
84 Specify user preferences for dependency solving for this run.
85 Overrides both $OPAMCRITERIA and $OPAMUPGRADECRITERIA. For details
86 on the supported language, and the external solvers available, see
87 http://opam.ocaml.org/doc/External_solvers.html. A general guide to
88 using solver preferences can be found at
89 http://www.dicosmo.org/Articles/usercriteria.pdf.
90 --cudf=FILENAME
92 Debug option: Save the CUDF requests sent to the solver to
93 FILENAME-<n>.cudf.
94 --debug
96 Print debug message to stderr. This is equivalent to setting
97 $OPAMDEBUG to "true".
98 --debug-level=LEVEL
100 Like --debug, but allows specifying the debug level (--debug sets
101 it to 1). Equivalent to setting $OPAMDEBUG to a positive integer.
102 --git-version
104 Print the git version of opam, if set (i.e. you are using a
105 development version), and exit.
106 --help[=FMT] (default=auto)
108 Show this help in format FMT. The value FMT must be one of auto,
109 pager, groff or plain. With auto, the format is pager or plain
110 whenever the TERM env var is dumb or undefined.
111 --ignore-pin-depends
113 Ignore extra pins required by packages that get pinned, either
114 manually through opam pin or through opam install DIR. This is
115 equivalent to setting IGNOREPINDEPENDS=true.
116 --json=FILENAME
118 Save the results of the opam run in a computer-readable file. If
119 the filename contains the character `%', it will be replaced by an
120 index that doesn't overwrite an existing file. Similar to setting
121 the $OPAMJSON variable.
122 --no-aspcud
124 Removed in 2.1.
125 --no-auto-upgrade
127 When configuring or updating a repository that is written for an
128 earlier opam version (1.2), opam internally converts it to the
129 current format. This disables this behaviour. Note that
130 repositories should define their format version in a 'repo' file at
131 their root, or they will be assumed to be in the older format. It
132 is, in any case, preferable to upgrade the repositories manually
133 using opam admin upgrade [--mirror URL] when possible.
134 --no-self-upgrade
136 Opam will replace itself with a newer binary found at OPAMROOT/opam
137 if present. This disables this behaviour.
138 -q, --quiet
140 Disables --verbose.
141 --root=ROOT
143 Use ROOT as the current root path. This is equivalent to setting
144 $OPAMROOT to ROOT.
145 --safe, --readonly
147 Make sure nothing will be automatically updated or rewritten.
148 Useful for calling from completion scripts, for example. Will fail
149 whenever such an operation is needed ; also avoids waiting for
150 locks, skips interactive questions and overrides the $OPAMDEBUG
151 variable. This is equivalent to set environment variable $OPAMSAFE.
152 --solver=CMD
154 Specify the CUDF solver to use for resolving package installation
155 problems. This is either a predefined solver (this version of opam
156 supports builtin-mccs+lp(), builtin-mccs+glpk,
157 builtin-dummy-z3-solver, builtin-dummy-0install-solver, aspcud,
158 mccs, aspcud-old, packup), or a custom command that should contain
159 the variables %{input}%, %{output}%, %{criteria}%, and optionally
160 %{timeout}%. This is equivalent to setting $OPAMEXTERNALSOLVER.
161 --strict
163 Fail whenever an error is found in a package definition or a
164 configuration file. The default is to continue silently if
165 possible.
166 --switch=SWITCH
168 Use SWITCH as the current compiler switch. This is equivalent to
169 setting $OPAMSWITCH to SWITCH.
170 --use-internal-solver
172 Disable any external solver, and use the built-in one (this
173 requires that opam has been compiled with a built-in solver). This
174 is equivalent to setting $OPAMNOASPCUD or $OPAMUSEINTERNALSOLVER.
175 -v, --verbose
177 Be more verbose. One -v shows all package commands, repeat to also
178 display commands called internally (e.g. tar, curl, patch etc.)
179 Repeating n times is equivalent to setting $OPAMVERBOSE to "n".
180 --version
182 Show version information.
183 -w, --working-dir
185 Whenever updating packages that are bound to a local,
186 version-controlled directory, update to the current working state
187 of their source instead of the last committed state, or the ref
188 they are pointing to. As source directory is copied as it is, if it
189 isn't clean it may result on a opam build failure.This only affects
190 packages explicitly listed on the command-line.It can also be set
191 with $OPAMWORKINGDIR.
192
194 Opam makes use of the environment variables listed here. Boolean
195 variables should be set to "0", "no", "false" or the empty string to
196 disable, "1", "yes" or "true" to enable.
197 OPAMALLPARENS surround all filters with parenthesis.
199 OPAMASSUMEDEPEXTS see option `--assume-depexts'.
201 OPAMAUTOREMOVE see remove option `--auto-remove'.
203 OPAMBESTEFFORT see option `--best-effort'.
205 OPAMBESTEFFORTPREFIXCRITERIA sets the string that must be prepended to
207 the criteria when the `--best-effort' option is set, and is expected to
208 maximise the `opam-query' property in the solution.
209 OPAMBUILDDOC Removed in 2.1.
211 OPAMBUILDTEST Removed in 2.1.
213 OPAMCLI see option `--cli'.
215 OPAMCOLOR when set to always or never, sets a default value for the
217 `--color' option.
218 OPAMCONFIRMLEVEL see option `--confirm-level`. OPAMCONFIRMLEVEL has
220 priority over OPAMYES and OPAMNO.
221 OPAMCRITERIA specifies user preferences for dependency solving. The
223 default value depends on the solver version, use `config report' to
224 know the current setting. See also option --criteria.
225 OPAMCUDFFILE save the cudf graph to file-actions-explicit.dot.
227 OPAMCUDFTRIM controls the filtering of unrelated packages during CUDF
229 preprocessing.
230 OPAMCURL can be used to select a given 'curl' program. See OPAMFETCH
232 for more options.
233 OPAMDEBUG see options `--debug' and `--debug-level'.
235 OPAMDEBUGSECTIONS if set, limits debug messages to the space-separated
237 list of sections. Sections can optionally have a specific debug level
238 (for example, CLIENT:2 or CLIENT CUDF:2), but otherwise use
239 `--debug-level'.
240 OPAMDIGDEPTH defines how aggressive the lookup for conflicts during
242 CUDF preprocessing is.
243 OPAMDOWNLOADJOBS sets the maximum number of simultaneous downloads.
245 OPAMDROPWORKINGDIR overrides packages previously updated with
247 --working-dir on update. Without this variable set, opam would keep
248 them unchanged unless explicitly named on the command-line.
249 OPAMDRYRUN see option `--dry-run'.
251 OPAMEDITOR sets the editor to use for opam file editing, overrides
253 $EDITOR and $VISUAL.
254 OPAMERRLOGLEN sets the number of log lines printed when a sub-process
256 fails. 0 to print all.
257 OPAMEXTERNALSOLVER see option `--solver'.
259 OPAMFAKE see option `--fake'.
261 OPAMFETCH specifies how to download files: either `wget', `curl' or a
263 custom command where variables %{url}%, %{out}%, %{retry}%,
264 %{compress}% and %{checksum}% will be replaced. Overrides the
265 'download-command' value from the main config file.
266 OPAMFIXUPCRITERIA same as OPAMUPGRADECRITERIA, but specific to fixup.
268 OPAMIGNORECONSTRAINTS see install option `--ignore-constraints-on'.
270 OPAMIGNOREPINDEPENDS see option `--ignore-pin-depends'.
272 OPAMINPLACEBUILD see option `--inplace-build'.
274 OPAMJOBS sets the maximum number of parallel workers to run.
276 OPAMJSON log json output to the given file (use character `%' to index
278 the files).
279 OPAMKEEPBUILDDIR see install option `--keep-build-dir'.
281 OPAMKEEPLOGS tells opam to not remove some temporary command logs and
283 some backups. This skips some finalisers and may also help to get more
284 reliable backtraces.
285 OPAMLOCKED combination of `--locked' and `--lock-suffix' options.
287 OPAMLOGS logdir sets log directory, default is a temporary directory in
289 /tmp
290 OPAMMAKECMD set the system make command to use.
292 OPAMMERGEOUT merge process outputs, stderr on stdout.
294 OPAMNO answer no to any question asked, see options `--no` and
296 `--confirm-level`. OPAMNO is ignored if either OPAMCONFIRMLEVEL or
297 OPAMYES is set.
298 OPAMNOAGGREGATE with `opam admin check', don't aggregate packages.
300 OPAMNOASPCUD Deprecated.
302 OPAMNOAUTOUPGRADE disables automatic internal upgrade of repositories
304 in an earlier format to the current one, on 'update' or 'init'.
305 OPAMNOCHECKSUMS enables option --no-checksums when available.
307 OPAMNODEPEXTS disables system dependencies handling, see option
309 `--no-depexts'.
310 OPAMNOENVNOTICE Internal.
312 OPAMNOSELFUPGRADE see option `--no-self-upgrade'
314 OPAMPINKINDAUTO sets whether version control systems should be detected
316 when pinning to a local path. Enabled by default since 1.3.0.
317 OPAMPRECISETRACKING fine grain tracking of directories.
319 OPAMPREPRO set this to false to disable CUDF preprocessing. Less
321 efficient, but might help debugging solver issue.
322 OPAMREQUIRECHECKSUMS Enables option `--require-checksums' when
324 available (e.g. for `opam install').
325 OPAMRETRIES sets the number of tries before failing downloads.
327 OPAMREUSEBUILDDIR see option `--reuse-build-dir'.
329 OPAMROOT see option `--root'. This is automatically set by `opam env
331 --root=DIR --set-root'.
332 OPAMROOTISOK don't complain when running as root.
334 OPAMSAFE see option `--safe'.
336 OPAMSHOW see option `--show'.
338 OPAMSKIPUPDATE see option `--skip-updates'.
340 OPAMSKIPVERSIONCHECKS bypasses some version checks. Unsafe, for
342 compatibility testing only.
343 OPAMSOLVERALLOWSUBOPTIMAL (default `true') allows some solvers to still
345 return a solution when they reach timeout; while the solution remains
346 assured to be consistent, there is no guarantee in this case that it
347 fits the expected optimisation criteria. If `true', opam willcontinue
348 with a warning, if `false' a timeout is an error. Currently only the
349 builtin-z3 backend handles this degraded case.
350 OPAMSOLVERTIMEOUT change the time allowance of the solver. Default is
352 60.0, set to 0 for unlimited. Note that all solvers may not support
353 this option.
354 OPAMSTATS display stats at the end of command.
356 OPAMSTATUSLINE display a dynamic status line showing what's currently
358 going on on the terminal. (one of one of always, never or auto)
359 OPAMSTRICT fail on inconsistencies (file reading, switch import, etc.).
361 OPAMSWITCH see option `--switch'. Automatically set by `opam env
363 --switch=SWITCH --set-switch'.
364 OPAMUNLOCKBASE see install option `--unlock-base'.
366 OPAMUPGRADECRITERIA specifies user preferences for dependency solving
368 when performing an upgrade. Overrides OPAMCRITERIA in upgrades if both
369 are set. See also option --criteria.
370 OPAMUSEINTERNALSOLVER see option `--use-internal-solver'.
372 OPAMUSEOPENSSL force openssl use for hash computing.
374 OPAMUTF8 use UTF8 characters in output (one of one of always, never or
376 auto). By default `auto', which is determined from the locale).
377 OPAMUTF8MSGS use extended UTF8 characters (camels) in opam messages.
379 Implies OPAMUTF8. This is set by default on OSX only.
380 OPAMVALIDATIONHOOK if set, uses the `%{hook%}' command to validate an
382 opam repository update.
383 OPAMVERBOSE see option `--verbose'.
385 OPAMVERSIONLAGPOWER do not use.
387 OPAMWITHDOC see install option `--with-doc'.
389 OPAMWITHTEST see install option `--with-test.
391 OPAMWORKINGDIR see option `--working-dir'.
393 OPAMYES see options `--yes' and `--confirm-level`. OPAMYES has has
395 priority over OPAMNO and is ignored if OPAMCONFIRMLEVEL is set.
396 OPAMVAR_var overrides the contents of the variable var when
398 substituting `%{var}%` strings in `opam` files.
399 OPAMVAR_package_var overrides the contents of the variable package:var
401 when substituting `%{package:var}%` strings in `opam` files.
402
404 All scripts and programmatic invocations of opam should use `--cli' in
405 order to ensure that they work seamlessly with future versions of the
406 opam client. Additionally, blog posts or other documentation can
407 benefit, as it prevents information from becoming stale.
408 Although opam only supports roots (~/.opam/) for the current version,
410 it does provide backwards compatibility for its command-line interface.
411 Since CLI version support was only added in opam 2.1, use OPAMCLI to
413 select 2.0 support (as opam 2.0 will just ignore it), and `--cli=2.1'
414 for 2.1 (or later) versions, since an environment variable controlling
415 the parsing of syntax is brittle. To this end, opam displays a warning
416 if OPAMCLI specifies a valid version other than 2.0, and also if
417 `--cli=2.0' is specified.
418 The command-line version is selected by using the `--cli' option or the
420 OPAMCLI environment variable. `--cli' may be specified morethan once,
421 where the last instance takes precedence. OPAMCLI is only inspected if
422 `--cli' is not given.
423
425 As an exception to the following, the `exec' command returns 127 if the
426 command was not found or couldn't be executed, and the command's exit
427 value otherwise.
428 0 Success, or true for boolean queries.
430 1 False. Returned when a boolean return value is expected, e.g. when
432 running with --check, or for queries like opam lint.
433 2 Bad command-line arguments, or command-line arguments pointing to
435 an invalid context (e.g. file not following the expected format).
436 5 Not found. You requested something (package, version, repository,
438 etc.) that couldn't be found.
439 10 Aborted. The operation required confirmation, which wasn't given.
441 15 Could not acquire the locks required for the operation.
443 20 There is no solution to the user request. This can be caused by
445 asking to install two incompatible packages, for example.
446 30 Error in package definition, or other metadata files. Using
448 --strict raises this error more often.
449 31 Package script error. Some package operations were unsuccessful.
451 This may be an error in the packages or an incompatibility with
452 your system. This can be a partial error.
453 40 Sync error. Could not fetch some remotes from the network. This can
455 be a partial error.
456 50 Configuration error. Opam or system configuration doesn't allow
458 operation, and needs fixing.
459 60 Solver failure. The solver failed to return a sound answer. It can
461 be due to a broken external solver, or an error in solver
462 configuration.
463 99 Internal error. Something went wrong, likely due to a bug in opam
465 itself.
466 130 User interrupt. SIGINT was received, generally due to the user
468 pressing Ctrl-C.
