DUNE-TOP(1) Dune Manual DUNE-TOP(1)

NAME

dune-top - Print a list of toplevel directives for including directories and loading cma files.

SYNOPSIS

dune top [OPTION]... [DIR]

DESCRIPTION

Print a list of toplevel directives for including directories and loading cma files.

The output of dune toplevel-init-file should be evaluated in a toplevel to make a library available there.

OPTIONS

--build-info
Show build information.
--context=CONTEXT (absent=default)
Select context where to build/run utop.
-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
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
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.

MORE HELP

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

Specified build directory. _build if unspecified
Activate binary cache (either `disabled' or `enabled'). Default is `disabled'.

Binary cache duplication mode
Binary cache protocol
Disable all promotion rules
"Enable instrumentation by BACKENDS. BACKENDS is a comma-separated list of library names, each one of which must declare an instrumentation backend.
Build profile. dev if unspecified or release if -p is set.
Sandboxing mode to use by default. (see --sandbox)
Store original source location in dune-package metadata
Use this specific workspace file instead of looking it up.
