NAME

       dune-compute - Compute internal function.

SYNOPSIS

       dune compute [OPTION]... FUNCTION [INPUT]

DESCRIPTION

       Run a registered memoize function with the given input and print the output.

       This should only be used for debugging dune.

ARGUMENTS

       FUNCTION (required)
           Compute FUNCTION for a given input.

       INPUT
           Use INPUT as the input to the function.

OPTIONS

       --build-info
           Show build information.

       -f, --force
           Force actions associated to aliases to be re-executed even if their dependencies
           haven't changed.

       --help[=FMT] (default=auto)
           Show this help in format FMT. The value FMT must be one of `auto', `pager', `groff' or
           `plain'. With `auto', the format is `pager` or `plain' whenever the TERM env var is
           `dumb' or undefined.

       --sandbox=VAL (absent DUNE_SANDBOX env)
           Sandboxing mode to use by default. Some actions require a certain sandboxing mode, so
           they will ignore this setting. The allowed values are: none, symlink, copy.

       --version
           Show version information.

       -w, --watch
           Instead of terminating build after completion, wait continuously for file changes.

COMMON OPTIONS

       These options are common to all commands.

       --always-show-command-line
           Always show the full command lines of programs executed by dune

       --auto-promote
           Automatically promote files. This is similar to running dune promote after the build.

       --build-dir=FILE (absent DUNE_BUILD_DIR env)
           Specified build directory. _build if unspecified

       --cache=VAL (absent DUNE_CACHE env)
           Activate binary cache (either `disabled' or `enabled'). Default is `disabled'.

       --cache-check-probability=VAL (absent=0. or DUNE_CACHE_CHECK_PROBABILITY env)
           Probability cached rules are rerun to check for reproducibility

       --cache-duplication=VAL (absent DUNE_CACHE_DUPLICATION env)
           Binary cache duplication mode

       --cache-transport=VAL (absent DUNE_CACHE_TRANSPORT env)
           Binary cache protocol

       --config-file=FILE
           Load this configuration file instead of the default one.

       --debug-artifact-substitution
           Print debugging info about artifact substitution

       --debug-backtraces
           Always print exception backtraces.

       --debug-dependency-path
           In case of error, print the dependency path from the targets on the command line to
           the rule that failed.

       --debug-findlib
           Debug the findlib sub-system.

       --default-target=TARGET (absent=@@default)
           Set the default target that when none is specified to dune build.

       --diff-command=VAL
           Shell command to use to diff files. Use - to disable printing the diff.

       --disable-promotion (absent DUNE_DISABLE_PROMOTION env)
           Disable all promotion rules

       --display=MODE
           Control the display mode of Dune. See dune-config(5) for more details.

       --ignore-promoted-rules
           Ignore rules with (mode promote), except ones with (only ...). The variable
           %{ignoring_promoted_rules} in dune files reflects whether this option was passed or
           not.

       --instrument-with=BACKENDS (absent DUNE_INSTRUMENT_WITH env)
           "Enable instrumentation by BACKENDS. BACKENDS is a comma-separated list of library
           names, each one of which must declare an instrumentation backend.

       -j JOBS
           Run no more than JOBS commands simultaneously.

       --no-buffer
           Do not buffer the output of commands executed by dune. By default dune buffers the
           output of subcommands, in order to prevent interleaving when multiple commands are
           executed in parallel. However, this can be an issue when debugging long running tests.
           With --no-buffer, commands have direct access to the terminal. Note that as a result
           their output won't be captured in the log file. You should use this option in
           conjunction with -j 1, to avoid interleaving. Additionally you should use --verbose as
           well, to make sure that commands are printed before they are being executed.

       --no-config
           Do not load the configuration file

       --no-print-directory
           Suppress "Entering directory" messages

       --only-packages=PACKAGES
           Ignore stanzas referring to a package that is not in PACKAGES. PACKAGES is a
           comma-separated list of package names. Note that this has the same effect as deleting
           the relevant stanzas from dune files. It is mostly meant for releases. During
           development, it is likely that what you want instead is to build a particular
           <package>.install target.

       -p PACKAGES, --for-release-of-packages=PACKAGES (required)
           Shorthand for --release --only-packages PACKAGE. You must use this option in your
           <package>.opam files, in order to build only what's necessary when your project
           contains multiple packages as well as getting reproducible builds.

       --profile=VAL (absent DUNE_PROFILE env)
           Select the build profile, for instance dev or release. The default is dev.

       --promote-install-files[=VAL] (default=true)
           Promote the generated <package>.install files to the source tree

       --release
           Put dune into a reproducible release mode. This is in fact a shorthand for --root .
           --ignore-promoted-rules --no-config --profile release --always-show-command-line
           --promote-install-files --default-target @install. You should use this option for
           release builds. For instance, you must use this option in your <package>.opam files.
           Except if you already use -p, as -p implies this option.

       --root=DIR
           Use this directory as workspace root instead of guessing it. Note that this option
           doesn't change the interpretation of targets given on the command line. It is only
           intended for scripts.

       --store-orig-source-dir (absent DUNE_STORE_ORIG_SOURCE_DIR env)
           Store original source location in dune-package metadata

       --terminal-persistence=MODE
           Changes how the log of build results are displayed to the console between rebuilds
           while in --watch mode. Supported modes: preserve, clear-on-rebuild.

       --trace-file=FILE
           Output trace data in catapult format (compatible with chrome://tracing)

       --verbose
           Same as --display verbose

       --workspace=FILE (absent DUNE_WORKSPACE env)
           Use this specific workspace file instead of looking it up.

       -x VAL
           Cross-compile using this toolchain.
