1dune-compute(1) Dune Manual dune-compute(1)
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-backtraces
80 Always print exception backtraces.
81 --debug-dependency-path
83 In case of error, print the dependency path from the targets on the
84 command line to the rule that failed.
85 --debug-findlib
87 Debug the findlib sub-system.
88 --default-target=TARGET (absent=@@default)
90 Set the default target that when none is specified to dune build.
91 --diff-command=VAL
93 Shell command to use to diff files. Use - to disable printing the
94 diff.
95 --disable-promotion (absent DUNE_DISABLE_PROMOTION env)
97 Disable all promotion rules
98 --display=MODE
100 Control the display mode of Dune. See dune-config(5) for more
101 details.
102 --ignore-promoted-rules
104 Ignore rules with (mode promote), except ones with (only ...). The
105 variable %{ignoring_promoted_rules} in dune files reflects whether
106 this option was passed or not.
107 -j JOBS
109 Run no more than JOBS commands simultaneously.
110 --no-buffer
112 Do not buffer the output of commands executed by dune. By default
113 dune buffers the output of subcommands, in order to prevent
114 interleaving when multiple commands are executed in parallel.
115 However, this can be an issue when debugging long running tests.
116 With --no-buffer, commands have direct access to the terminal. Note
117 that as a result their output won't be captured in the log file.
118 You should use this option in conjunction with -j 1, to avoid
119 interleaving. Additionally you should use --verbose as well, to
120 make sure that commands are printed before they are being executed.
121 --no-config
123 Do not load the configuration file
124 --no-print-directory
126 Suppress "Entering directory" messages
127 --only-packages=PACKAGES
129 Ignore stanzas referring to a package that is not in PACKAGES.
130 PACKAGES is a comma-separated list of package names. Note that this
131 has the same effect as deleting the relevant stanzas from dune
132 files. It is mostly meant for releases. During development, it is
133 likely that what you want instead is to build a particular
134 <package>.install target.
135 -p PACKAGES, --for-release-of-packages=PACKAGES
137 Shorthand for --release --only-packages PACKAGE. You must use this
138 option in your <package>.opam files, in order to build only what's
139 necessary when your project contains multiple packages as well as
140 getting reproducible builds.
141 --profile=VAL (absent DUNE_PROFILE env)
143 Select the build profile, for instance dev or release. The default
144 is dev.
145 --promote-install-files
147 Promote the generated <package>.install files to the source tree
148 --release
150 Put dune into a reproducible release mode. This is in fact a
151 shorthand for --root . --ignore-promoted-rules --no-config
152 --profile release --always-show-command-line
153 --promote-install-files --default-target @install. You should use
154 this option for release builds. For instance, you must use this
155 option in your <package>.opam files. Except if you already use -p,
156 as -p implies this option.
157 --root=DIR
159 Use this directory as workspace root instead of guessing it. Note
160 that this option doesn't change the interpretation of targets given
161 on the command line. It is only intended for scripts.
162 --store-orig-source-dir (absent DUNE_STORE_ORIG_SOURCE_DIR env)
164 Store original source location in dune-package metadata
165 --terminal-persistence=MODE
167 Changes how the log of build results are displayed to the console
168 between rebuilds while in --watch mode.
169 --trace-file=FILE
171 Output trace data in catapult format (compatible with
172 chrome://tracing)
173 --verbose
175 Same as --display verbose
176 --workspace=FILE (absent DUNE_WORKSPACE env)
178 Use this specific workspace file instead of looking it up.
179 -x VAL
181 Cross-compile using this toolchain.
182
184 Use `dune COMMAND --help' for help on a single command.
185
187 These environment variables affect the execution of compute:
188 DUNE_BUILD_DIR
190 Specified build directory. _build if unspecified
191 DUNE_CACHE
193 Activate binary cache (either `disabled' or `enabled'). Default is
194 `disabled'.
195 DUNE_CACHE_CHECK_PROBABILITY
197 Probability cached rules are rerun to check for reproducibility
198 DUNE_CACHE_DUPLICATION
200 Binary cache duplication mode
201 DUNE_CACHE_TRANSPORT
203 Binary cache protocol
204 DUNE_DISABLE_PROMOTION
206 Disable all promotion rules
207 DUNE_PROFILE
209 Build profile. dev if unspecified or release if -p is set.
210 DUNE_SANDBOX
212 Sandboxing mode to use by default. (see --sandbox)
213 DUNE_STORE_ORIG_SOURCE_DIR
215 Store original source location in dune-package metadata
216 DUNE_WORKSPACE
218 Use this specific workspace file instead of looking it up.
