12 dune upgrade upgrades all the projects in the workspace to the latest
13 major version of Dune
14
16 --action-stderr-on-success=VAL
17 Same as --action-stdout-on-success but for the standard output for
18 error messages. A good default for large mono-repositories is
19 --action-stdout-on-success=swallow
20 --action-stderr-on-success=must-be-empty. This ensures that a
21 successful build has a "clean" empty output.
22 --action-stdout-on-success=VAL
24 Specify how to deal with the standard output of actions when they
25 succeed. Possible values are: print to just print it to Dune's
26 output, swallow to completely ignore it and must-be-empty to
27 enforce that the action printed nothing. With must-be-empty, Dune
28 will consider that the action failed if it printed something to its
29 standard output. The default is print.
30 --build-info
32 Show build information.
33 --display-separate-messages
35 Separate error messages with a blank line.
36 --error-reporting=VAL (absent=deterministic)
38 Controls when the build errors are reported. early - report errors
39 as soon as they are discovered. deterministic - report errors at
40 the end of the build in a deterministic order. twice - report each
41 error twice: once as soon as the error is discovered and then again
42 at the end of the build, in a deterministic order.
43 -f, --force
45 Force actions associated to aliases to be re-executed even if their
46 dependencies haven't changed.
47 --file-watcher=VAL (absent=automatic)
49 Mechanism to detect changes in the source. Automatic to make dune
50 run an external program to detect changes. Manual to notify dune
51 that files have changed manually."
52 --passive-watch-mode
54 Similar to [--watch], but only start a build when instructed
55 externally by an RPC.
56 --react-to-insignificant-changes
58 react to insignificant file system changes; this is only useful for
59 benchmarking dune
60 --sandbox=VAL (absent DUNE_SANDBOX env)
62 Sandboxing mode to use by default. Some actions require a certain
63 sandboxing mode, so they will ignore this setting. The allowed
64 values are: none, symlink, copy, hardlink.
65 -w, --watch
67 Instead of terminating build after completion, wait continuously
68 for file changes.
69 --wait-for-filesystem-clock
71 Dune digest file contents for better incrementally. These digests
72 are themselves cached. In some cases, Dune needs to drop some
73 digest cache entries in order for things to be reliable. This
74 option makes Dune wait for the file system clock to advance so that
75 it doesn't need to drop anything. You should probably not care
76 about this option; it is mostly useful for Dune developers to make
77 Dune tests of the digest cache more reproducible.
78
80 These options are common to all commands.
81 --always-show-command-line
83 Always show the full command lines of programs executed by dune
84 --auto-promote
86 Automatically promote files. This is similar to running dune
87 promote after the build.
88 --build-dir=FILE (absent DUNE_BUILD_DIR env)
90 Specified build directory. _build if unspecified
91 --cache=VAL (absent DUNE_CACHE env)
93 Enable or disable Dune cache (either enabled or disabled). Default
94 is `disabled'.
95 --cache-check-probability=VAL (absent DUNE_CACHE_CHECK_PROBABILITY env)
97 Check build reproducibility by re-executing randomly chosen rules
98 and comparing their results with those stored in Dune cache. Note:
99 by increasing the probability of such checks you slow down the
100 build. The default probability is zero, i.e. no rules are checked.
101 --cache-storage-mode=VAL (absent DUNE_CACHE_STORAGE_MODE env)
103 Dune cache storage mode (one of auto, hardlink or copy). Default is
104 `auto'.
105 --config-file=FILE
107 Load this configuration file instead of the default one.
108 --debug-artifact-substitution
110 Print debugging info about artifact substitution
111 --debug-backtraces
113 Always print exception backtraces.
114 --debug-cache=VAL
116 Show debug messages on cache misses for the given cache layers.
117 Value is a comma-separated list of cache layer names. All available
118 cache layers: shared,workspace-local,fs.
119 --debug-dependency-path
121 In case of error, print the dependency path from the targets on the
122 command line to the rule that failed.
123 --debug-digests
125 Explain why Dune decides to re-digest some files
126 --debug-load-dir
128 Print debugging info about directory loading
129 --debug-store-digest-preimage
131 Store digest preimage for all computed digests, so that it's
132 possible to reverse them later, for debugging. The digests are
133 stored in the shared cache (see --cache flag) as values, even if
134 cache is otherwise disabled. This should be used only for
135 debugging, since it's slow and it litters the shared cache.
136 --default-target=TARGET (absent=@@default)
138 Set the default target that when none is specified to dune build.
139 --diff-command=VAL (absent DUNE_DIFF_COMMAND env)
141 Shell command to use to diff files. Use - to disable printing the
142 diff.
143 --disable-promotion (absent DUNE_DISABLE_PROMOTION env)
145 Disable all promotion rules
146 --display=MODE
148 Control the display mode of Dune. See dune-config(5) for more
149 details. Valid values for this option are progress, verbose, short,
150 quiet or tui.
151 --dump-gc-stats=FILE
153 Dump the garbage collector stats to a file after the build is
154 complete.
155 --dump-memo-graph=FILE
157 Dumps the dependency graph to a file after the build is complete
158 --dump-memo-graph-format=FORMAT (absent=gexf)
160 File format to be used when dumping dependency graph
161 --dump-memo-graph-with-timing
163 With --dump-memo-graph, will re-run each cached node in the Memo
164 graph after building and include the runtime in the output. Since
165 all nodes contain a cached value, this will measure just the
166 runtime of each node
167 --help[=FMT] (default=auto)
169 Show this help in format FMT. The value FMT must be one of auto,
170 pager, groff or plain. With auto, the format is pager or plain
171 whenever the TERM env var is dumb or undefined.
172 --ignore-promoted-rules
174 Ignore rules with (mode promote), except ones with (only ...). The
175 variable %{ignoring_promoted_rules} in dune files reflects whether
176 this option was passed or not.
177 --instrument-with=BACKENDS (absent DUNE_INSTRUMENT_WITH env)
179 "Enable instrumentation by BACKENDS. BACKENDS is a comma-separated
180 list of library names, each one of which must declare an
181 instrumentation backend.
182 -j JOBS
184 Run no more than JOBS commands simultaneously.
185 --no-buffer
187 Do not buffer the output of commands executed by dune. By default
188 dune buffers the output of subcommands, in order to prevent
189 interleaving when multiple commands are executed in parallel.
190 However, this can be an issue when debugging long running tests.
191 With --no-buffer, commands have direct access to the terminal. Note
192 that as a result their output won't be captured in the log file.
193 You should use this option in conjunction with -j 1, to avoid
194 interleaving. Additionally you should use --verbose as well, to
195 make sure that commands are printed before they are being executed.
196 --no-config
198 Do not load the configuration file
199 --no-print-directory
201 Suppress "Entering directory" messages
202 --only-packages=PACKAGES
204 Ignore stanzas referring to a package that is not in PACKAGES.
205 PACKAGES is a comma-separated list of package names. Note that this
206 has the same effect as deleting the relevant stanzas from dune
207 files. It is mostly meant for releases. During development, it is
208 likely that what you want instead is to build a particular
209 <package>.install target.
210 -p PACKAGES, --for-release-of-packages=PACKAGES (required)
212 Shorthand for --release --only-packages PACKAGE. You must use this
213 option in your <package>.opam files, in order to build only what's
214 necessary when your project contains multiple packages as well as
215 getting reproducible builds.
216 --print-metrics
218 Print out various performance metrics after every build
219 --profile=VAL (absent DUNE_PROFILE env)
221 Select the build profile, for instance dev or release. The default
222 is dev.
223 --promote-install-files[=VAL] (default=true)
225 Promote the generated <package>.install files to the source tree
226 --release
228 Put dune into a reproducible release mode. This is in fact a
229 shorthand for --root . --ignore-promoted-rules --no-config
230 --profile release --always-show-command-line
231 --promote-install-files --default-target @install
232 --require-dune-project-file. You should use this option for release
233 builds. For instance, you must use this option in your
234 <package>.opam files. Except if you already use -p, as -p implies
235 this option.
236 --require-dune-project-file[=VAL] (default=true)
238 Fail if a dune-project file is missing.
239 --root=DIR
241 Use this directory as workspace root instead of guessing it. Note
242 that this option doesn't change the interpretation of targets given
243 on the command line. It is only intended for scripts.
244 --store-orig-source-dir (absent DUNE_STORE_ORIG_SOURCE_DIR env)
246 Store original source location in dune-package metadata
247 --terminal-persistence=MODE
249 Changes how the log of build results are displayed to the console
250 between rebuilds while in --watch mode. Supported modes: preserve,
251 clear-on-rebuild, clear-on-rebuild-and-flush-history.
252 --trace-extended
254 Output extended trace data (requires trace-file)
255 --trace-file=FILE
257 Output trace data in catapult format (compatible with
258 chrome://tracing)
259 --verbose
261 Same as --display verbose
262 --version
264 Show version information.
265 --watch-exclusions=REGEX
267 Adds a POSIX regular expression that will exclude matching
268 directories from `dune build --watch`. The option
269 --watch-exclusions can be repeated to add multiple exclusions.
270 Semicolons can be also used as a separator. If no exclusions are
271 provided, then a standard set of exclusions is used; however, if
272 one or more --watch-exclusions are used, none of the standard
273 exclusions are used. The standard exclusions are: ^_opam /_opam
274 ^_esy /_esy ^\.#.* /\.#.* ~$ ^#[^#]*#$ /#[^#]*#$ ^4913$ /4913$
275 /.git /.hg :/windows
276 --workspace=FILE (absent DUNE_WORKSPACE env)
278 Use this specific workspace file instead of looking it up.
279 -x VAL
281 Cross-compile using this toolchain.
282
284 Use `dune COMMAND --help' for help on a single command.
285
287 upgrade exits with the following status:
288 0 on success.
290 1 if an error happened.
292 130 if it was interrupted by a signal.
294

300 DUNE_CACHE
302 Enable or disable Dune cache (either enabled or disabled). Default
303 is `disabled'.
304 DUNE_CACHE_CHECK_PROBABILITY
306 Check build reproducibility by re-executing randomly chosen rules
307 and comparing their results with those stored in Dune cache. Note:
308 by increasing the probability of such checks you slow down the
309 build. The default probability is zero, i.e. no rules are checked.
310 DUNE_CACHE_STORAGE_MODE
312 Dune cache storage mode (one of auto, hardlink or copy). Default is
313 `auto'.

325 instrumentation backend.
326 DUNE_PROFILE
328 Build profile. dev if unspecified or release if -p is set.
329 DUNE_SANDBOX
331 Sandboxing mode to use by default. (see --sandbox)
332 DUNE_STORE_ORIG_SOURCE_DIR
334 Store original source location in dune-package metadata
