6 opam-upgrade - Upgrade the installed package to latest version.
7
9 opam upgrade [OPTION]... [PACKAGES]...
10
12 This command upgrades the installed packages to their latest available
13 versions. More precisely, this command calls the dependency solver to
14 find a consistent state where most of the installed packages are
15 upgraded to their latest versions.
16
17 If a directory is specified as argument, anything that is pinned to
18 that directory is selected for upgrade.
19
21 PACKAGES
22 List of package names, with an optional version or constraint, e.g
23 `pkg', `pkg.1.0' or `pkg>=0.5' ; or directory names containing
24 package description, with explicit directory (e.g. `./srcdir' or
25 `.')
26
28 -a, --all
29 Run an upgrade of all installed packages. This is the default if
30 PACKAGES was not specified, and can be useful with PACKAGES to
31 upgrade while ensuring that some packages get or remain installed.
32
33 --check
34 Don't run the upgrade: just check if anything could be upgraded.
35 Returns 0 if that is the case, 1 if there is nothing that can be
36 upgraded.
37
38 --fixup
39 Recover from a broken state (eg. missing dependencies, two
40 conflicting packages installed together...).
41
42 --installed
43 When a directory is provided as argument, do not install pinned
44 package that are not yet installed.
45
46 -j JOBS, --jobs=JOBS
47 Set the maximal number of concurrent jobs to use. The default value
48 is calculated from the number of cores. You can also set it using
49 the $OPAMJOBS environment variable.
50
51 --no
52 Answer no to all opam yes/no questions without prompting. See also
53 --confirm-level. This is equivalent to setting $OPAMNO to "true".
54
55 -y, --yes
56 Answer yes to all opam yes/no questions without prompting. See also
57 --confirm-level. This is equivalent to setting $OPAMYES to "true".
58
60 --assume-depexts
61 Skip the installation step for any missing system packages, and
62 attempt to proceed with compilation of the opam packages anyway. If
63 the installation is successful, opam won't prompt again about these
64 system packages. Only meaningful if external dependency handling is
65 enabled.
66
67 -b, --keep-build-dir
68 Keep the build directories after compiling packages. This is
69 equivalent to setting $OPAMKEEPBUILDDIR to "true".
70
71 --build-doc
72 Removed in 2.1, use --with-doc instead.
73
74 --build-test
75 Removed in 2.1, use --with-test instead.
76
77 -d, --with-doc
78 Build the package documentation. This only affects packages listed
79 on the command-line. This is equivalent to setting $OPAMWITHDOC (or
80 the deprecated $OPAMBUILDDOC) to "true".
81
82 --dry-run
83 Simulate the command, but don't actually perform any changes. This
84 also can be set with environment variable $OPAMDEBUG.
85
86 --fake
87 This option registers the actions into the opam database, without
88 actually performing them. WARNING: This option is dangerous and
89 likely to break your opam environment. You probably want --dry-run.
90 You've been warned.
91
92 --ignore-constraints-on[=PACKAGES] (default=)
93 Forces opam to ignore version constraints on all dependencies to
94 the listed packages. This can be used to test compatibility, but
95 expect builds to break when using this. Note that version
96 constraints on optional dependencies and conflicts are unaffected.
97 This is equivalent to setting $OPAMIGNORECONSTRAINTS.
98
99 --inplace-build
100 When compiling a package which has its source bound to a local
101 directory, process the build and install actions directly in that
102 directory, rather than in a clean copy handled by opam. This only
103 affects packages that are explicitly listed on the command-line.
104 This is equivalent to setting $OPAMINPLACEBUILD to "true".
105
106 --lock-suffix=SUFFIX (absent=locked)
107 Set locked files suffix to SUFFIX.
108
109 --locked
110 In commands that use opam files found from pinned sources, if a
111 variant of the file with an added .locked extension is found (e.g.
112 foo.opam.locked besides foo.opam), that will be used instead. This
113 is typically useful to offer a more specific set of dependencies
114 and reproduce similar build contexts, hence the name. The
115 lockoption can be used to generate such files, based on the
116 versions of the dependencies currently installed on the host. This
117 is equivalent to setting the $OPAMLOCKED environment variable. Note
118 that this option doesn't generally affect already pinned packages.
119
120 -m MAKE, --make=MAKE
121 Removed in 2.1, use opam config set[-global] make MAKE instead.
122
123 --no-checksums
124 Do not verify the checksum of downloaded archives.This is
125 equivalent to setting $OPAMNOCHECKSUMS to "true".
126
127 --no-depexts
128 Temporarily disables handling of external dependencies. This can be
129 used if a package is not available on your system package manager,
130 but you installed the required dependency by hand. Implies
131 --assume-depexts, and stores the exceptions upon success as well.
132
133 --require-checksums
134 Reject the installation of packages that don't provide a checksum
135 for the upstream archives. This is equivalent to setting
136 $OPAMREQUIRECHECKSUMS to "true".
137
138 --reuse-build-dir
139 Reuse existing build directories (kept by using --keep-build-dir),
140 instead of compiling from a fresh clone of the source. This can be
141 faster, but also lead to failures if the build systems of the
142 packages don't handle upgrades of dependencies well. This is
143 equivalent to setting $OPAMREUSEBUILDDIR to "true".
144
145 --show-actions
146 Call the solver and display the actions. Don't perform any changes.
147 This is equivalent to setting $OPAMSHOW.
148
149 --skip-updates
150 When running an install, upgrade or reinstall on source-pinned
151 packages, they are normally updated from their origin first. This
152 flag disables that behaviour and will keep them to their version in
153 cache. This is equivalent to setting $OPAMSKIPUPDATE.
154
155 -t, --with-test
156 Build and run the package unit-tests. This only affects packages
157 listed on the command-line. This is equivalent to setting
158 $OPAMWITHTEST (or the deprecated $OPAMBUILDTEST) to "true".
159
160 --unlock-base
161 Removed in 2.1, use --update-invariant instead.
162
163 --update-invariant
164 Allow changes to the packages set as switch base (typically, the
165 main compiler). Use with caution. This is equivalent to setting the
166 $OPAMUNLOCKBASE environment variable
167
169 These options are common to all commands.
170
171 --best-effort
172 Don't fail if all requested packages can't be installed: try to
173 install as many as possible. Note that not all external solvers may
174 support this option (recent versions of aspcud or mccs should).
175 This is equivalent to setting $OPAMBESTEFFORT environment variable.
176
177 --cli=MAJOR.MINOR (absent=2.1)
178 Use the command-line interface syntax and semantics of MAJOR.MINOR.
179 Intended for any persistent use of opam (scripts, blog posts,
180 etc.), any version of opam in the same MAJOR series will behave as
181 for the specified MINOR release. The flag was not available in opam
182 2.0, so to select the 2.0 CLI, set the OPAMCLI environment variable
183 to 2.0 instead of using this parameter.
184
185 --color=WHEN
186 Colorize the output. WHEN must be one of `always', `never' or
187 `auto'.
188
189 --confirm-level=LEVEL
190 Confirmation level, LEVEL must be one of `ask', `no', `yes' or
191 `unsafe-yes'. Can be specified more than once. If --yes or --no are
192 also given, the value of the last --confirm-level is taken into
193 account. This is equivalent to setting $OPAMCONFIRMLEVEL`.
194
195 --criteria=CRITERIA
196 Specify user preferences for dependency solving for this run.
197 Overrides both $OPAMCRITERIA and $OPAMUPGRADECRITERIA. For details
198 on the supported language, and the external solvers available, see
199 http://opam.ocaml.org/doc/External_solvers.html. A general guide to
200 using solver preferences can be found at
201 http://www.dicosmo.org/Articles/usercriteria.pdf.
202
203 --cudf=FILENAME
204 Debug option: Save the CUDF requests sent to the solver to
205 FILENAME-<n>.cudf.
206
207 --debug
208 Print debug message to stderr. This is equivalent to setting
209 $OPAMDEBUG to "true".
210
211 --debug-level=LEVEL
212 Like --debug, but allows specifying the debug level (--debug sets
213 it to 1). Equivalent to setting $OPAMDEBUG to a positive integer.
214
215 --git-version
216 Print the git version of opam, if set (i.e. you are using a
217 development version), and exit.
218
219 --help[=FMT] (default=auto)
220 Show this help in format FMT. The value FMT must be one of `auto',
221 `pager', `groff' or `plain'. With `auto', the format is `pager` or
222 `plain' whenever the TERM env var is `dumb' or undefined.
223
224 --ignore-pin-depends
225 Ignore extra pins required by packages that get pinned, either
226 manually through opam pin or through opam install DIR. This is
227 equivalent to setting IGNOREPINDEPENDS=true.
228
229 --json=FILENAME
230 Save the results of the opam run in a computer-readable file. If
231 the filename contains the character `%', it will be replaced by an
232 index that doesn't overwrite an existing file. Similar to setting
233 the $OPAMJSON variable.
234
235 --no-aspcud
236 Removed in 2.1.
237
238 --no-auto-upgrade
239 When configuring or updating a repository that is written for an
240 earlier opam version (1.2), opam internally converts it to the
241 current format. This disables this behaviour. Note that
242 repositories should define their format version in a 'repo' file at
243 their root, or they will be assumed to be in the older format. It
244 is, in any case, preferable to upgrade the repositories manually
245 using opam admin upgrade [--mirror URL] when possible.
246
247 --no-self-upgrade
248 Opam will replace itself with a newer binary found at OPAMROOT/opam
249 if present. This disables this behaviour.
250
251 -q, --quiet
252 Disables --verbose.
253
254 --root=ROOT
255 Use ROOT as the current root path. This is equivalent to setting
256 $OPAMROOT to ROOT.
257
258 --safe, --readonly
259 Make sure nothing will be automatically updated or rewritten.
260 Useful for calling from completion scripts, for example. Will fail
261 whenever such an operation is needed ; also avoids waiting for
262 locks, skips interactive questions and overrides the $OPAMDEBUG
263 variable. This is equivalent to set environment variable $OPAMSAFE.
264
265 --solver=CMD
266 Specify the CUDF solver to use for resolving package installation
267 problems. This is either a predefined solver (this version of opam
268 supports builtin-mccs+lp(), builtin-mccs+glpk,
269 builtin-dummy-z3-solver, builtin-dummy-0install-solver, aspcud,
270 mccs, aspcud-old, packup), or a custom command that should contain
271 the variables %{input}%, %{output}%, %{criteria}%, and optionally
272 %{timeout}%. This is equivalent to setting $OPAMEXTERNALSOLVER.
273
274 --strict
275 Fail whenever an error is found in a package definition or a
276 configuration file. The default is to continue silently if
277 possible.
278
279 --switch=SWITCH
280 Use SWITCH as the current compiler switch. This is equivalent to
281 setting $OPAMSWITCH to SWITCH.
282
283 --use-internal-solver
284 Disable any external solver, and use the built-in one (this
285 requires that opam has been compiled with a built-in solver). This
286 is equivalent to setting $OPAMNOASPCUD or $OPAMUSEINTERNALSOLVER.
287
288 -v, --verbose
289 Be more verbose. One -v shows all package commands, repeat to also
290 display commands called internally (e.g. tar, curl, patch etc.)
291 Repeating n times is equivalent to setting $OPAMVERBOSE to "n".
292
293 --version
294 Show version information.
295
296 -w, --working-dir
297 Whenever updating packages that are bound to a local,
298 version-controlled directory, update to the current working state
299 of their source instead of the last committed state, or the ref
300 they are pointing to. As source directory is copied as it is, if it
301 isn't clean it may result on a opam build failure.This only affects
302 packages explicitly listed on the command-line.It can also be set
303 with $OPAMWORKINGDIR.
304
306 Opam makes use of the environment variables listed here. Boolean
307 variables should be set to "0", "no", "false" or the empty string to
308 disable, "1", "yes" or "true" to enable.
309
310 OPAMALLPARENS surround all filters with parenthesis.
311
312 OPAMASSUMEDEPEXTS see option `--assume-depexts'.
313
314 OPAMAUTOREMOVE see remove option `--auto-remove'.
315
316 OPAMBESTEFFORT see option `--best-effort'.
317
318 OPAMBESTEFFORTPREFIXCRITERIA sets the string that must be prepended to
319 the criteria when the `--best-effort' option is set, and is expected to
320 maximise the `opam-query' property in the solution.
321
322 OPAMBUILDDOC Removed in 2.1.
323
324 OPAMBUILDTEST Removed in 2.1.
325
326 OPAMCLI see option `--cli'.
327
328 OPAMCOLOR when set to always or never, sets a default value for the
329 `--color' option.
330
331 OPAMCONFIRMLEVEL see option `--confirm-level`. OPAMCONFIRMLEVEL has
332 priority over OPAMYES and OPAMNO.
333
334 OPAMCRITERIA specifies user preferences for dependency solving. The
335 default value depends on the solver version, use `config report' to
336 know the current setting. See also option --criteria.
337
338 OPAMCUDFFILE save the cudf graph to file-actions-explicit.dot.
339
340 OPAMCUDFTRIM controls the filtering of unrelated packages during CUDF
341 preprocessing.
342
343 OPAMCURL can be used to select a given 'curl' program. See OPAMFETCH
344 for more options.
345
346 OPAMDEBUG see options `--debug' and `--debug-level'.
347
348 OPAMDEBUGSECTIONS if set, limits debug messages to the space-separated
349 list of sections. Sections can optionally have a specific debug level
350 (for example, CLIENT:2 or CLIENT CUDF:2), but otherwise use
351 `--debug-level'.
352
353 OPAMDIGDEPTH defines how aggressive the lookup for conflicts during
354 CUDF preprocessing is.
355
356 OPAMDOWNLOADJOBS sets the maximum number of simultaneous downloads.
357
358 OPAMDROPWORKINGDIR overrides packages previously updated with
359 --working-dir on update. Without this variable set, opam would keep
360 them unchanged unless explicitly named on the command-line.
361
362 OPAMDRYRUN see option `--dry-run'.
363
364 OPAMEDITOR sets the editor to use for opam file editing, overrides
365 $EDITOR and $VISUAL.
366
367 OPAMERRLOGLEN sets the number of log lines printed when a sub-process
368 fails. 0 to print all.
369
370 OPAMEXTERNALSOLVER see option `--solver'.
371
372 OPAMFAKE see option `--fake'.
373
374 OPAMFETCH specifies how to download files: either `wget', `curl' or a
375 custom command where variables %{url}%, %{out}%, %{retry}%,
376 %{compress}% and %{checksum}% will be replaced. Overrides the
377 'download-command' value from the main config file.
378
379 OPAMFIXUPCRITERIA same as OPAMUPGRADECRITERIA, but specific to fixup.
380
381 OPAMIGNORECONSTRAINTS see install option `--ignore-constraints-on'.
382
383 OPAMIGNOREPINDEPENDS see option `--ignore-pin-depends'.
384
385 OPAMINPLACEBUILD see option `--inplace-build'.
386
387 OPAMJOBS sets the maximum number of parallel workers to run.
388
389 OPAMJSON log json output to the given file (use character `%' to index
390 the files).
391
392 OPAMKEEPBUILDDIR see install option `--keep-build-dir'.
393
394 OPAMKEEPLOGS tells opam to not remove some temporary command logs and
395 some backups. This skips some finalisers and may also help to get more
396 reliable backtraces.
397
398 OPAMLOCKED combination of `--locked' and `--lock-suffix' options.
399
400 OPAMLOGS logdir sets log directory, default is a temporary directory in
401 /tmp
402
403 OPAMMAKECMD set the system make command to use.
404
405 OPAMMERGEOUT merge process outputs, stderr on stdout.
406
407 OPAMNO answer no to any question asked, see options `--no` and
408 `--confirm-level`. OPAMNO is ignored if either OPAMCONFIRMLEVEL or
409 OPAMYES is set.
410
411 OPAMNOAGGREGATE with `opam admin check', don't aggregate packages.
412
413 OPAMNOASPCUD Deprecated.
414
415 OPAMNOAUTOUPGRADE disables automatic internal upgrade of repositories
416 in an earlier format to the current one, on 'update' or 'init'.
417
418 OPAMNOCHECKSUMS enables option --no-checksums when available.
419
420 OPAMNODEPEXTS disables system dependencies handling, see option
421 `--no-depexts'.
422
423 OPAMNOENVNOTICE Internal.
424
425 OPAMNOSELFUPGRADE see option `--no-self-upgrade'
426
427 OPAMPINKINDAUTO sets whether version control systems should be detected
428 when pinning to a local path. Enabled by default since 1.3.0.
429
430 OPAMPRECISETRACKING fine grain tracking of directories.
431
432 OPAMPREPRO set this to false to disable CUDF preprocessing. Less
433 efficient, but might help debugging solver issue.
434
435 OPAMREQUIRECHECKSUMS Enables option `--require-checksums' when
436 available (e.g. for `opam install').
437
438 OPAMRETRIES sets the number of tries before failing downloads.
439
440 OPAMREUSEBUILDDIR see option `--reuse-build-dir'.
441
442 OPAMROOT see option `--root'. This is automatically set by `opam env
443 --root=DIR --set-root'.
444
445 OPAMROOTISOK don't complain when running as root.
446
447 OPAMSAFE see option `--safe'.
448
449 OPAMSHOW see option `--show'.
450
451 OPAMSKIPUPDATE see option `--skip-updates'.
452
453 OPAMSKIPVERSIONCHECKS bypasses some version checks. Unsafe, for
454 compatibility testing only.
455
456 OPAMSOLVERALLOWSUBOPTIMAL (default `true') allows some solvers to still
457 return a solution when they reach timeout; while the solution remains
458 assured to be consistent, there is no guarantee in this case that it
459 fits the expected optimisation criteria. If `true', opam willcontinue
460 with a warning, if `false' a timeout is an error. Currently only the
461 builtin-z3 backend handles this degraded case.
462
463 OPAMSOLVERTIMEOUT change the time allowance of the solver. Default is
464 60.0, set to 0 for unlimited. Note that all solvers may not support
465 this option.
466
467 OPAMSTATS display stats at the end of command.
468
469 OPAMSTATUSLINE display a dynamic status line showing what's currently
470 going on on the terminal. (one of one of `always', `never' or `auto')
471
472 OPAMSTRICT fail on inconsistencies (file reading, switch import, etc.).
473
474 OPAMSWITCH see option `--switch'. Automatically set by `opam env
475 --switch=SWITCH --set-switch'.
476
477 OPAMUNLOCKBASE see install option `--unlock-base'.
478
479 OPAMUPGRADECRITERIA specifies user preferences for dependency solving
480 when performing an upgrade. Overrides OPAMCRITERIA in upgrades if both
481 are set. See also option --criteria.
482
483 OPAMUSEINTERNALSOLVER see option `--use-internal-solver'.
484
485 OPAMUSEOPENSSL force openssl use for hash computing.
486
487 OPAMUTF8 use UTF8 characters in output (one of one of `always', `never'
488 or `auto'). By default `auto', which is determined from the locale).
489
490 OPAMUTF8MSGS use extended UTF8 characters (camels) in opam messages.
491 Implies OPAMUTF8. This is set by default on OSX only.
492
493 OPAMVALIDATIONHOOK if set, uses the `%{hook%}' command to validate an
494 opam repository update.
495
496 OPAMVERBOSE see option `--verbose'.
497
498 OPAMVERSIONLAGPOWER do not use.
499
500 OPAMWITHDOC see install option `--with-doc'.
501
502 OPAMWITHTEST see install option `--with-test.
503
504 OPAMWORKINGDIR see option `--working-dir'.
505
506 OPAMYES see options `--yes' and `--confirm-level`. OPAMYES has has
507 priority over OPAMNO and is ignored if OPAMCONFIRMLEVEL is set.
508
509 OPAMVAR_var overrides the contents of the variable var when
510 substituting `%{var}%` strings in `opam` files.
511
512 OPAMVAR_package_var overrides the contents of the variable package:var
513 when substituting `%{package:var}%` strings in `opam` files.
514
516 All scripts and programmatic invocations of opam should use `--cli' in
517 order to ensure that they work seamlessly with future versions of the
518 opam client. Additionally, blog posts or other documentation can
519 benefit, as it prevents information from becoming stale.
520
521 Although opam only supports roots (~/.opam/) for the current version,
522 it does provide backwards compatibility for its command-line interface.
523
524 Since CLI version support was only added in opam 2.1, use OPAMCLI to
525 select 2.0 support (as opam 2.0 will just ignore it), and `--cli=2.1'
526 for 2.1 (or later) versions, since an environment variable controlling
527 the parsing of syntax is brittle. To this end, opam displays a warning
528 if OPAMCLI specifies a valid version other than 2.0, and also if
529 `--cli=2.0' is specified.
530
531 The command-line version is selected by using the `--cli' option or the
532 OPAMCLI environment variable. `--cli' may be specified morethan once,
533 where the last instance takes precedence. OPAMCLI is only inspected if
534 `--cli' is not given.
535
537 As an exception to the following, the `exec' command returns 127 if the
538 command was not found or couldn't be executed, and the command's exit
539 value otherwise.
540
541 0 Success, or true for boolean queries.
542
543 1 False. Returned when a boolean return value is expected, e.g. when
544 running with --check, or for queries like opam lint.
545
546 2 Bad command-line arguments, or command-line arguments pointing to
547 an invalid context (e.g. file not following the expected format).
548
549 5 Not found. You requested something (package, version, repository,
550 etc.) that couldn't be found.
551
552 10 Aborted. The operation required confirmation, which wasn't given.
553
554 15 Could not acquire the locks required for the operation.
555
556 20 There is no solution to the user request. This can be caused by
557 asking to install two incompatible packages, for example.
558
559 30 Error in package definition, or other metadata files. Using
560 --strict raises this error more often.
561
562 31 Package script error. Some package operations were unsuccessful.
563 This may be an error in the packages or an incompatibility with
564 your system. This can be a partial error.
565
566 40 Sync error. Could not fetch some remotes from the network. This can
567 be a partial error.
568
569 50 Configuration error. Opam or system configuration doesn't allow
570 operation, and needs fixing.
571
572 60 Solver failure. The solver failed to return a sound answer. It can
