2
6 dune-compute - Compute internal function.
7
9 dune compute [OPTION]... FUNCTION [INPUT]
10
12 Run a registered memoize function with the given input and print the
13 output.
14 This should only be used for debugging dune.
16
18 FUNCTION (required)
19 Compute FUNCTION for a given input.
20 INPUT
22 Use INPUT as the input to the function.
23
25 --build-info
26 Show build information.
27 -f, --force
29 Force actions associated to aliases to be re-executed even if their
30 dependencies haven't changed.
31 --help[=FMT] (default=auto)
33 Show this help in format FMT. The value FMT must be one of `auto',
34 `pager', `groff' or `plain'. With `auto', the format is `pager` or
35 `plain' whenever the TERM env var is `dumb' or undefined.
36 --sandbox=VAL (absent DUNE_SANDBOX env)
38 Sandboxing mode to use by default. Some actions require a certain
39 sandboxing mode, so they will ignore this setting. The allowed
40 values are: none, symlink, copy.
41 --version
43 Show version information.
44 -w, --watch
46 Instead of terminating build after completion, wait continuously
47 for file changes.
48
50 These options are common to all commands.
51 --always-show-command-line
53 Always show the full command lines of programs executed by dune
54 --auto-promote
56 Automatically promote files. This is similar to running dune
57 promote after the build.
58 --build-dir=FILE (absent DUNE_BUILD_DIR env)
60 Specified build directory. _build if unspecified
61 --cache=VAL (absent DUNE_CACHE env)
63 Activate binary cache (either `disabled' or `enabled'). Default is
64 `disabled'.
65 --cache-check-probability=VAL (absent=0. or
67 DUNE_CACHE_CHECK_PROBABILITY env)
68 Probability cached rules are rerun to check for reproducibility
69 --cache-duplication=VAL (absent DUNE_CACHE_DUPLICATION env)
71 Binary cache duplication mode
72 --cache-transport=VAL (absent DUNE_CACHE_TRANSPORT env)
74 Binary cache protocol
75 --config-file=FILE
77 Load this configuration file instead of the default one.
78 --debug-artifact-substitution
80 Print debugging info about artifact substitution
81 --debug-backtraces
83 Always print exception backtraces.
84 --debug-dependency-path
86 In case of error, print the dependency path from the targets on the
87 command line to the rule that failed.
88 --debug-findlib
90 Debug the findlib sub-system.
91 --default-target=TARGET (absent=@@default)
93 Set the default target that when none is specified to dune build.
94 --diff-command=VAL
96 Shell command to use to diff files. Use - to disable printing the
97 diff.
98 --disable-promotion (absent DUNE_DISABLE_PROMOTION env)
100 Disable all promotion rules
101 --display=MODE
103 Control the display mode of Dune. See dune-config(5) for more
104 details.
105 --ignore-promoted-rules
107 Ignore rules with (mode promote), except ones with (only ...). The
108 variable %{ignoring_promoted_rules} in dune files reflects whether
109 this option was passed or not.
110 --instrument-with=BACKENDS (absent DUNE_INSTRUMENT_WITH env)
112 "Enable instrumentation by BACKENDS. BACKENDS is a comma-separated
113 list of library names, each one of which must declare an
114 instrumentation backend.
115 -j JOBS
117 Run no more than JOBS commands simultaneously.
118 --no-buffer
120 Do not buffer the output of commands executed by dune. By default
121 dune buffers the output of subcommands, in order to prevent
122 interleaving when multiple commands are executed in parallel.
123 However, this can be an issue when debugging long running tests.
124 With --no-buffer, commands have direct access to the terminal. Note
125 that as a result their output won't be captured in the log file.
126 You should use this option in conjunction with -j 1, to avoid
127 interleaving. Additionally you should use --verbose as well, to
128 make sure that commands are printed before they are being executed.
129 --no-config
131 Do not load the configuration file
132 --no-print-directory
134 Suppress "Entering directory" messages
135 --only-packages=PACKAGES
137 Ignore stanzas referring to a package that is not in PACKAGES.
138 PACKAGES is a comma-separated list of package names. Note that this
139 has the same effect as deleting the relevant stanzas from dune
140 files. It is mostly meant for releases. During development, it is
141 likely that what you want instead is to build a particular
142 <package>.install target.
143 -p PACKAGES, --for-release-of-packages=PACKAGES
145 Shorthand for --release --only-packages PACKAGE. You must use this
146 option in your <package>.opam files, in order to build only what's
147 necessary when your project contains multiple packages as well as
148 getting reproducible builds.
149 --profile=VAL (absent DUNE_PROFILE env)
151 Select the build profile, for instance dev or release. The default
152 is dev.
153 --promote-install-files
155 Promote the generated <package>.install files to the source tree
156 --release
158 Put dune into a reproducible release mode. This is in fact a
159 shorthand for --root . --ignore-promoted-rules --no-config
160 --profile release --always-show-command-line
161 --promote-install-files --default-target @install. You should use
162 this option for release builds. For instance, you must use this
163 option in your <package>.opam files. Except if you already use -p,
164 as -p implies this option.
165 --root=DIR
167 Use this directory as workspace root instead of guessing it. Note
168 that this option doesn't change the interpretation of targets given
169 on the command line. It is only intended for scripts.
170 --store-orig-source-dir (absent DUNE_STORE_ORIG_SOURCE_DIR env)
172 Store original source location in dune-package metadata
173 --terminal-persistence=MODE
175 Changes how the log of build results are displayed to the console
176 between rebuilds while in --watch mode.
177 --trace-file=FILE
179 Output trace data in catapult format (compatible with
180 chrome://tracing)
181 --verbose
183 Same as --display verbose
184 --workspace=FILE (absent DUNE_WORKSPACE env)
186 Use this specific workspace file instead of looking it up.
187 -x VAL
189 Cross-compile using this toolchain.
190
192 Use `dune COMMAND --help' for help on a single command.
193
195 These environment variables affect the execution of compute:
196 DUNE_BUILD_DIR
198 Specified build directory. _build if unspecified
199 DUNE_CACHE
201 Activate binary cache (either `disabled' or `enabled'). Default is
202 `disabled'.
203 DUNE_CACHE_CHECK_PROBABILITY
205 Probability cached rules are rerun to check for reproducibility
206 DUNE_CACHE_DUPLICATION
208 Binary cache duplication mode
209 DUNE_CACHE_TRANSPORT
211 Binary cache protocol
212 DUNE_DISABLE_PROMOTION
214 Disable all promotion rules
215 DUNE_INSTRUMENT_WITH
217 "Enable instrumentation by BACKENDS. BACKENDS is a comma-separated
218 list of library names, each one of which must declare an
219 instrumentation backend.
220 DUNE_PROFILE
222 Build profile. dev if unspecified or release if -p is set.
223 DUNE_SANDBOX
225 Sandboxing mode to use by default. (see --sandbox)
226 DUNE_STORE_ORIG_SOURCE_DIR
228 Store original source location in dune-package metadata
229 DUNE_WORKSPACE
231 Use this specific workspace file instead of looking it up.
