1OPAM-LIST(1) Opam Manual OPAM-LIST(1)
2
6 opam-list - Display the list of available packages.
7
9 opam list [OPTION]… [PATTERNS]…
10
12 List selections of opam packages.
13 Without argument, the command displays the list of currently installed
15 packages. With pattern arguments, lists all available packages matching
16 one of the patterns.
17 Unless the --short switch is used, the output format displays one
19 package per line, and each line contains the name of the package, the
20 installed version or `--' if the package is not installed, and a short
21 description. In color mode, manually installed packages (as opposed to
22 automatically installed ones because of dependencies) are underlined.
23 See section PACKAGE SELECTION OPTIONS for all the ways to select the
25 packages to be displayed, and section OUTPUT FORMAT OPTIONS to
26 customise the output format.
27 For a more detailed description of packages, see opam show. For
29 extended search capabilities within the packages' metadata, see opam
30 search.
31
33 PATTERNS
34 Package patterns with globs. Unless --search is specified, they
35 match againsta NAME or NAME.VERSION
36
38 -a, --available
39 List only packages that are available on the current system
40 -A, --all
42 Include all, even uninstalled or unavailable packages
43 --base
45 List only the immutable base of the current switch (i.e. compiler
46 packages)
47 --coinstallable-with=PACKAGES
49 Only list packages that are compatible with all of PACKAGES.
50 --conflicts-with=PACKAGES
52 List packages that have declared conflicts with at least one of the
53 given list. This includes conflicts defined from the packages in
54 the list, from the other package, or by a common conflict-class:
55 field.
56 --depends-on=PACKAGES
58 List only packages that depend on one of (comma-separated)
59 PACKAGES.
60 --depopts
62 Include optional dependencies in dependency requests.
63 --dev
65 Include development packages in dependencies.
66 --field-match=FIELD:PATTERN
68 Filter packages with a match for PATTERN on the given FIELD
69 --has-flag=FLAG
71 Only include packages which have the given flag set. Package flags
72 are one of: light-uninstall verbose plugin compiler conf
73 --has-tag=TAG
75 Only includes packages which have the given tag set
76 -i, --installed
78 List installed packages only. This is the default when no further
79 arguments are supplied
80 --installable
82 List only packages that can be installed on the current switch
83 (this calls the solver and may be more costly; a package depending
84 on an unavailable package may be available, but is never
85 installable)
86 --no-switch
88 List what is available from the repositories, without consideration
89 for the current (or any other) switch (installed or pinned
90 packages, etc.)
91 --nobuild
93 Exclude build dependencies (they are included by default).
94 --or
96 Instead of selecting packages that match all the criteria, select
97 packages that match any of them
98 --owns-file=FILE
100 Finds installed packages responsible for installing the given file
101 --pinned
103 List only the pinned packages
104 --post
106 Include dependencies tagged as post.
107 --recursive
109 With `--depends-on' and `--required-by', display all transitive
110 dependencies rather than just direct dependencies.
111 --repos=REPOS
113 Include only packages that took their origin from one of the given
114 repositories (unless no-switch is also specified, this excludes
115 pinned packages).
116 --required-by=PACKAGES
118 List only the dependencies of (comma-separated) PACKAGES.
119 --resolve=PACKAGES
121 Restrict to a solution to install (comma-separated) PACKAGES, i.e.
122 a consistent set of packages including those. This is subtly
123 different from `--required-by --recursive`, which is more
124 predictable and can't fail, but lists all dependencies
125 independently without ensuring consistency. Without `--installed`,
126 the answer is self-contained and independent of the current
127 installation. With `--installed', it's computed from the set of
128 currently installed packages. `--no-switch` further makes the
129 solution independent from the currently pinned packages,
130 architecture, and compiler version. The combination with
131 `--depopts' is not supported.
132 --roots, --installed-roots
134 List only packages that were explicitly installed, excluding the
135 ones installed as dependencies
136 --search
138 Match PATTERNS against the full descriptions of packages, and
139 require all of them to match, instead of requiring at least one to
140 match against package names (unless --or is also specified).
141 -t, --with-test, --test
143 Include test-only dependencies.
144 --with-doc, --doc
146 Include doc-only dependencies.
147
149 --columns=COLUMNS
150 Select the columns to display among: name, version, package,
151 synopsis, synopsis-or-target, description, <field>:,
152 installed-version, pin, source-hash, opam-file,
153 all-installed-versions, available-versions, all-versions,
154 repository, installed-files, vc-ref, depexts. The default is name
155 when --short is present and name, installed-version,
156 synopsis-or-target otherwise.
157 -e, --external, --depexts
159 Instead of displaying the packages, display their external
160 dependencies that are associated with the current system. This
161 excludes other display options. Rather than using this directly,
162 you should probably head for the `depext' plugin, that will use
163 your system package management system to handle the installation of
164 the dependencies. Run `opam depext'.
165 --normalise
167 Print the values of opam fields normalised
168 -S, --sort
170 Sort the packages in dependency order (i.e. an order in which they
171 could be individually installed.)
172 -s, --short
174 Don't print a header, and sets the default columns to name only. If
175 you need package versions included, use --columns=package instead
176 --separator=STRING (absent= )
178 Set the column-separator string
179 -V, --all-versions
181 Normally, when multiple versions of a package match, only one is
182 shown in the output (the installed one, the pinned-to one, or,
183 failing that, the highest one available or the highest one). This
184 flag disables this behaviour and shows all matching versions. This
185 also changes the default display format to include package versions
186 instead of just package names (including when --short is set). This
187 is automatically turned on when a single non-pattern package name
188 is provided on the command-line.
189 --vars=[VAR=STR,...]
191 Define the given variable bindings. Typically useful with
192 --external to override the values for arch, os, os-distribution,
193 os-version, os-family.
194 --wrap
196 Wrap long lines, the default being to truncate when displaying on a
197 terminal, or to keep as is otherwise
198
200 --check
201 Don't write anything in the output, exit with return code 0 if the
202 list is not empty, 1 otherwise.
203 --no
205 Answer no to all opam yes/no questions without prompting. See also
206 --confirm-level. This is equivalent to setting $OPAMNO to "true".
207 --no-depexts
209 Disable external dependencies handling for the query. This can be
210 used to include packages that are marked as unavailable because of
211 an unavailable system dependency.
212 --silent
214 Removed in 2.1, use --check instead.
215 -y, --yes
217 Answer yes to all opam yes/no questions without prompting. See also
218 --confirm-level. This is equivalent to setting $OPAMYES to "true".
219
221 These options are common to all commands.
222 --best-effort
224 Don't fail if all requested packages can't be installed: try to
225 install as many as possible. Note that not all external solvers may
226 support this option (recent versions of aspcud or mccs should).
227 This is equivalent to setting $OPAMBESTEFFORT environment variable.
228 --cli=MAJOR.MINOR (absent=2.1)
230 Use the command-line interface syntax and semantics of MAJOR.MINOR.
231 Intended for any persistent use of opam (scripts, blog posts,
232 etc.), any version of opam in the same MAJOR series will behave as
233 for the specified MINOR release. The flag was not available in opam
234 2.0, so to select the 2.0 CLI, set the OPAMCLI environment variable
235 to 2.0 instead of using this parameter.
236 --color=WHEN
238 Colorize the output. WHEN must be one of always, never or auto.
239 --confirm-level=LEVEL
241 Confirmation level, LEVEL must be one of ask, no, yes or
242 unsafe-yes. Can be specified more than once. If --yes or --no are
243 also given, the value of the last --confirm-level is taken into
244 account. This is equivalent to setting $OPAMCONFIRMLEVEL`.
245 --criteria=CRITERIA
247 Specify user preferences for dependency solving for this run.
248 Overrides both $OPAMCRITERIA and $OPAMUPGRADECRITERIA. For details
249 on the supported language, and the external solvers available, see
250 http://opam.ocaml.org/doc/External_solvers.html. A general guide to
251 using solver preferences can be found at
252 http://www.dicosmo.org/Articles/usercriteria.pdf.
253 --cudf=FILENAME
255 Debug option: Save the CUDF requests sent to the solver to
256 FILENAME-<n>.cudf.
257 --debug
259 Print debug message to stderr. This is equivalent to setting
260 $OPAMDEBUG to "true".
261 --debug-level=LEVEL
263 Like --debug, but allows specifying the debug level (--debug sets
264 it to 1). Equivalent to setting $OPAMDEBUG to a positive integer.
265 --git-version
267 Print the git version of opam, if set (i.e. you are using a
268 development version), and exit.
269 --help[=FMT] (default=auto)
271 Show this help in format FMT. The value FMT must be one of auto,
272 pager, groff or plain. With auto, the format is pager or plain
273 whenever the TERM env var is dumb or undefined.
274 --ignore-pin-depends
276 Ignore extra pins required by packages that get pinned, either
277 manually through opam pin or through opam install DIR. This is
278 equivalent to setting IGNOREPINDEPENDS=true.
279 --json=FILENAME
281 Save the results of the opam run in a computer-readable file. If
282 the filename contains the character `%', it will be replaced by an
283 index that doesn't overwrite an existing file. Similar to setting
284 the $OPAMJSON variable.
285 --no-aspcud
287 Removed in 2.1.
288 --no-auto-upgrade
290 When configuring or updating a repository that is written for an
291 earlier opam version (1.2), opam internally converts it to the
292 current format. This disables this behaviour. Note that
293 repositories should define their format version in a 'repo' file at
294 their root, or they will be assumed to be in the older format. It
295 is, in any case, preferable to upgrade the repositories manually
296 using opam admin upgrade [--mirror URL] when possible.
297 --no-self-upgrade
299 Opam will replace itself with a newer binary found at OPAMROOT/opam
300 if present. This disables this behaviour.
301 -q, --quiet
303 Disables --verbose.
304 --root=ROOT
306 Use ROOT as the current root path. This is equivalent to setting
307 $OPAMROOT to ROOT.
308 --safe, --readonly
310 Make sure nothing will be automatically updated or rewritten.
311 Useful for calling from completion scripts, for example. Will fail
312 whenever such an operation is needed ; also avoids waiting for
313 locks, skips interactive questions and overrides the $OPAMDEBUG
314 variable. This is equivalent to set environment variable $OPAMSAFE.
315 --solver=CMD
317 Specify the CUDF solver to use for resolving package installation
318 problems. This is either a predefined solver (this version of opam
319 supports builtin-mccs+lp(), builtin-mccs+glpk,
320 builtin-dummy-z3-solver, builtin-dummy-0install-solver, aspcud,
321 mccs, aspcud-old, packup), or a custom command that should contain
322 the variables %{input}%, %{output}%, %{criteria}%, and optionally
323 %{timeout}%. This is equivalent to setting $OPAMEXTERNALSOLVER.
324 --strict
326 Fail whenever an error is found in a package definition or a
327 configuration file. The default is to continue silently if
328 possible.
329 --switch=SWITCH
331 Use SWITCH as the current compiler switch. This is equivalent to
332 setting $OPAMSWITCH to SWITCH.
333 --use-internal-solver
335 Disable any external solver, and use the built-in one (this
336 requires that opam has been compiled with a built-in solver). This
337 is equivalent to setting $OPAMNOASPCUD or $OPAMUSEINTERNALSOLVER.
338 -v, --verbose
340 Be more verbose. One -v shows all package commands, repeat to also
341 display commands called internally (e.g. tar, curl, patch etc.)
342 Repeating n times is equivalent to setting $OPAMVERBOSE to "n".
343 --version
345 Show version information.
346 -w, --working-dir
348 Whenever updating packages that are bound to a local,
349 version-controlled directory, update to the current working state
350 of their source instead of the last committed state, or the ref
351 they are pointing to. As source directory is copied as it is, if it
352 isn't clean it may result on a opam build failure.This only affects
353 packages explicitly listed on the command-line.It can also be set
354 with $OPAMWORKINGDIR.
355
357 Opam makes use of the environment variables listed here. Boolean
358 variables should be set to "0", "no", "false" or the empty string to
359 disable, "1", "yes" or "true" to enable.
360 OPAMALLPARENS surround all filters with parenthesis.
362 OPAMASSUMEDEPEXTS see option `--assume-depexts'.
364 OPAMAUTOREMOVE see remove option `--auto-remove'.
366 OPAMBESTEFFORT see option `--best-effort'.
368 OPAMBESTEFFORTPREFIXCRITERIA sets the string that must be prepended to
370 the criteria when the `--best-effort' option is set, and is expected to
371 maximise the `opam-query' property in the solution.
372 OPAMBUILDDOC Removed in 2.1.
374 OPAMBUILDTEST Removed in 2.1.
376 OPAMCLI see option `--cli'.
378 OPAMCOLOR when set to always or never, sets a default value for the
380 `--color' option.
381 OPAMCONFIRMLEVEL see option `--confirm-level`. OPAMCONFIRMLEVEL has
383 priority over OPAMYES and OPAMNO.
384 OPAMCRITERIA specifies user preferences for dependency solving. The
386 default value depends on the solver version, use `config report' to
387 know the current setting. See also option --criteria.
388 OPAMCUDFFILE save the cudf graph to file-actions-explicit.dot.
390 OPAMCUDFTRIM controls the filtering of unrelated packages during CUDF
392 preprocessing.
393 OPAMCURL can be used to select a given 'curl' program. See OPAMFETCH
395 for more options.
396 OPAMDEBUG see options `--debug' and `--debug-level'.
398 OPAMDEBUGSECTIONS if set, limits debug messages to the space-separated
400 list of sections. Sections can optionally have a specific debug level
401 (for example, CLIENT:2 or CLIENT CUDF:2), but otherwise use
402 `--debug-level'.
403 OPAMDIGDEPTH defines how aggressive the lookup for conflicts during
405 CUDF preprocessing is.
406 OPAMDOWNLOADJOBS sets the maximum number of simultaneous downloads.
408 OPAMDROPWORKINGDIR overrides packages previously updated with
410 --working-dir on update. Without this variable set, opam would keep
411 them unchanged unless explicitly named on the command-line.
412 OPAMDRYRUN see option `--dry-run'.
414 OPAMEDITOR sets the editor to use for opam file editing, overrides
416 $EDITOR and $VISUAL.
417 OPAMERRLOGLEN sets the number of log lines printed when a sub-process
419 fails. 0 to print all.
420 OPAMEXTERNALSOLVER see option `--solver'.
422 OPAMFAKE see option `--fake'.
424 OPAMFETCH specifies how to download files: either `wget', `curl' or a
426 custom command where variables %{url}%, %{out}%, %{retry}%,
427 %{compress}% and %{checksum}% will be replaced. Overrides the
428 'download-command' value from the main config file.
429 OPAMFIXUPCRITERIA same as OPAMUPGRADECRITERIA, but specific to fixup.
431 OPAMIGNORECONSTRAINTS see install option `--ignore-constraints-on'.
433 OPAMIGNOREPINDEPENDS see option `--ignore-pin-depends'.
435 OPAMINPLACEBUILD see option `--inplace-build'.
437 OPAMJOBS sets the maximum number of parallel workers to run.
439 OPAMJSON log json output to the given file (use character `%' to index
441 the files).
442 OPAMKEEPBUILDDIR see install option `--keep-build-dir'.
444 OPAMKEEPLOGS tells opam to not remove some temporary command logs and
446 some backups. This skips some finalisers and may also help to get more
447 reliable backtraces.
448 OPAMLOCKED combination of `--locked' and `--lock-suffix' options.
450 OPAMLOGS logdir sets log directory, default is a temporary directory in
452 /tmp
453 OPAMMAKECMD set the system make command to use.
455 OPAMMERGEOUT merge process outputs, stderr on stdout.
457 OPAMNO answer no to any question asked, see options `--no` and
459 `--confirm-level`. OPAMNO is ignored if either OPAMCONFIRMLEVEL or
460 OPAMYES is set.
461 OPAMNOAGGREGATE with `opam admin check', don't aggregate packages.
463 OPAMNOASPCUD Deprecated.
465 OPAMNOAUTOUPGRADE disables automatic internal upgrade of repositories
467 in an earlier format to the current one, on 'update' or 'init'.
468 OPAMNOCHECKSUMS enables option --no-checksums when available.
470 OPAMNODEPEXTS disables system dependencies handling, see option
472 `--no-depexts'.
473 OPAMNOENVNOTICE Internal.
475 OPAMNOSELFUPGRADE see option `--no-self-upgrade'
477 OPAMPINKINDAUTO sets whether version control systems should be detected
479 when pinning to a local path. Enabled by default since 1.3.0.
480 OPAMPRECISETRACKING fine grain tracking of directories.
482 OPAMPREPRO set this to false to disable CUDF preprocessing. Less
484 efficient, but might help debugging solver issue.
485 OPAMREQUIRECHECKSUMS Enables option `--require-checksums' when
487 available (e.g. for `opam install').
488 OPAMRETRIES sets the number of tries before failing downloads.
490 OPAMREUSEBUILDDIR see option `--reuse-build-dir'.
492 OPAMROOT see option `--root'. This is automatically set by `opam env
494 --root=DIR --set-root'.
495 OPAMROOTISOK don't complain when running as root.
497 OPAMSAFE see option `--safe'.
499 OPAMSHOW see option `--show'.
501 OPAMSKIPUPDATE see option `--skip-updates'.
503 OPAMSKIPVERSIONCHECKS bypasses some version checks. Unsafe, for
505 compatibility testing only.
506 OPAMSOLVERALLOWSUBOPTIMAL (default `true') allows some solvers to still
508 return a solution when they reach timeout; while the solution remains
509 assured to be consistent, there is no guarantee in this case that it
510 fits the expected optimisation criteria. If `true', opam willcontinue
511 with a warning, if `false' a timeout is an error. Currently only the
512 builtin-z3 backend handles this degraded case.
513 OPAMSOLVERTIMEOUT change the time allowance of the solver. Default is
515 60.0, set to 0 for unlimited. Note that all solvers may not support
516 this option.
517 OPAMSTATS display stats at the end of command.
519 OPAMSTATUSLINE display a dynamic status line showing what's currently
521 going on on the terminal. (one of one of always, never or auto)
522 OPAMSTRICT fail on inconsistencies (file reading, switch import, etc.).
524 OPAMSWITCH see option `--switch'. Automatically set by `opam env
526 --switch=SWITCH --set-switch'.
527 OPAMUNLOCKBASE see install option `--unlock-base'.
529 OPAMUPGRADECRITERIA specifies user preferences for dependency solving
531 when performing an upgrade. Overrides OPAMCRITERIA in upgrades if both
532 are set. See also option --criteria.
533 OPAMUSEINTERNALSOLVER see option `--use-internal-solver'.
535 OPAMUSEOPENSSL force openssl use for hash computing.
537 OPAMUTF8 use UTF8 characters in output (one of one of always, never or
539 auto). By default `auto', which is determined from the locale).
540 OPAMUTF8MSGS use extended UTF8 characters (camels) in opam messages.
542 Implies OPAMUTF8. This is set by default on OSX only.
543 OPAMVALIDATIONHOOK if set, uses the `%{hook%}' command to validate an
545 opam repository update.
546 OPAMVERBOSE see option `--verbose'.
548 OPAMVERSIONLAGPOWER do not use.
550 OPAMWITHDOC see install option `--with-doc'.
552 OPAMWITHTEST see install option `--with-test.
554 OPAMWORKINGDIR see option `--working-dir'.
556 OPAMYES see options `--yes' and `--confirm-level`. OPAMYES has has
558 priority over OPAMNO and is ignored if OPAMCONFIRMLEVEL is set.
559 OPAMVAR_var overrides the contents of the variable var when
561 substituting `%{var}%` strings in `opam` files.
562 OPAMVAR_package_var overrides the contents of the variable package:var
564 when substituting `%{package:var}%` strings in `opam` files.
565
567 All scripts and programmatic invocations of opam should use `--cli' in
568 order to ensure that they work seamlessly with future versions of the
569 opam client. Additionally, blog posts or other documentation can
570 benefit, as it prevents information from becoming stale.
571 Although opam only supports roots (~/.opam/) for the current version,
573 it does provide backwards compatibility for its command-line interface.
574 Since CLI version support was only added in opam 2.1, use OPAMCLI to
576 select 2.0 support (as opam 2.0 will just ignore it), and `--cli=2.1'
577 for 2.1 (or later) versions, since an environment variable controlling
578 the parsing of syntax is brittle. To this end, opam displays a warning
579 if OPAMCLI specifies a valid version other than 2.0, and also if
580 `--cli=2.0' is specified.
581 The command-line version is selected by using the `--cli' option or the
583 OPAMCLI environment variable. `--cli' may be specified morethan once,
584 where the last instance takes precedence. OPAMCLI is only inspected if
585 `--cli' is not given.
586
588 As an exception to the following, the `exec' command returns 127 if the
589 command was not found or couldn't be executed, and the command's exit
590 value otherwise.
591 0 Success, or true for boolean queries.
593 1 False. Returned when a boolean return value is expected, e.g. when
595 running with --check, or for queries like opam lint.
596 2 Bad command-line arguments, or command-line arguments pointing to
598 an invalid context (e.g. file not following the expected format).
599 5 Not found. You requested something (package, version, repository,
601 etc.) that couldn't be found.
602 10 Aborted. The operation required confirmation, which wasn't given.
604 15 Could not acquire the locks required for the operation.
606 20 There is no solution to the user request. This can be caused by
608 asking to install two incompatible packages, for example.
609 30 Error in package definition, or other metadata files. Using
611 --strict raises this error more often.
612 31 Package script error. Some package operations were unsuccessful.
614 This may be an error in the packages or an incompatibility with
615 your system. This can be a partial error.
616 40 Sync error. Could not fetch some remotes from the network. This can
618 be a partial error.
619 50 Configuration error. Opam or system configuration doesn't allow
621 operation, and needs fixing.
622 60 Solver failure. The solver failed to return a sound answer. It can
624 be due to a broken external solver, or an error in solver
625 configuration.
626 99 Internal error. Something went wrong, likely due to a bug in opam
628 itself.
629 130 User interrupt. SIGINT was received, generally due to the user
631 pressing Ctrl-C.
