NAME

       dune - composable build system for OCaml

SYNOPSIS

       dune COMMAND ...

DESCRIPTION

       Dune is a build system designed for OCaml projects only. It focuses on providing the user
       with a consistent experience and takes care of most of the low-level details of OCaml
       compilation. All you have to do is provide a description of your project and Dune will do
       the rest.

       The scheme it implements is inspired from the one used inside Jane Street and adapted to
       the open source world. It has matured over a long time and is used daily by hundreds of
       developers, which means that it is highly tested and productive.

COMMANDS

           Build the given targets, or all installable targets if none are given.

       clean
           Clean the project.

       exec
           Execute a command in a similar environment as if installation was performed.

       external-lib-deps
           Print out external libraries needed to build the given targets.

       help
           Additional Dune help

       install
           Install packages.

       installed-libraries
           Print out libraries installed on the system.

       printenv
           Print the environment of a directory

       promote
           Promote files from the last run

       rules
           Dump internal rules.

       runtest
           Run tests.

       subst
           Substitute watermarks in source files.

       uninstall
           Uninstall packages.

       unstable-fmt
           Format dune files

       utop
           Load library in utop

OPTIONS

       -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.

       --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.

       --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

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

       --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
           Set the default target that when none is specified to dune build. It defaults to
           @@default.

       --dev
           Same as --profile dev

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

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

       --ignore-promoted-rules
           Ignore rules with (mode promote)

       -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

       --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 jbuild 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
           Shorthand for --root . --only-packages PACKAGE --ignore-promoted-rules --no-config
           --profile release. 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
           Select the build profile, for instance dev or release. The default is dev.

       --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.

       --stats
           Record and print statistics about Dune resource usage.

       --verbose
           Same as --display verbose

       --workspace=FILE
           Use this specific workspace file instead of looking it up.

       -x VAL
           Cross-compile using this toolchain.

MORE HELP

       Use `dune COMMAND --help' for help on a single command.

ENVIRONMENT

       These environment variables affect the execution of dune:

       DUNE_BUILD_DIR
           Specified build directory. _build if unspecified
