DUNE-SHUTDOWN(1)

NAME

dune-shutdown - cancel and shutdown any builds in the current workspace

SYNOPSIS

dune shutdown [OPTION]...

OPTIONS

--action-stderr-on-success=VAL
    Same as --action-stdout-on-success but for the standard output for error messages. A good default for large mono-repositories is --action-stdout-on-success=swallow --action-stderr-on-success=must-be-empty. This ensures that a successful build has a "clean" empty output.

--action-stdout-on-success=VAL
    Specify how to deal with the standard output of actions when they succeed. Possible values are: print to just print it to Dune's output, swallow to completely ignore it and must-be-empty to enforce that the action printed nothing. With must-be-empty, Dune will consider that the action failed if it printed something to its standard output. The default is print.

--build-info
    Show build information.

--error-reporting=VAL (absent=deterministic)
    Controls when the build errors are reported. early - report errors as soon as they are discovered. deterministic - report errors at the end of the build in a deterministic order. twice - report each error twice: once as soon as the error is discovered and then again at the end of the build, in a deterministic order.

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

--file-watcher=VAL (absent=automatic)
    Mechanism to detect changes in the source. Automatic to make dune run an external program to detect changes. Manual to notify dune that files have changed manually."

--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.

--passive-watch-mode
    Similar to [--watch], but only start a build when instructed externally by an RPC.

--react-to-insignificant-changes
    react to insignificant file system changes; this is only useful for benchmarking dune

--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, hardlink.

--version
    Show version information.

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

--wait-for-filesystem-clock
    Dune digest file contents for better incrementally. These digests are themselves cached. In some cases, Dune needs to drop some digest cache entries in order for things to be reliable. This option makes Dune wait for the file system clock to advance so that it doesn't need to drop anything. You should probably not care about this option; it is mostly useful for Dune developers to make Dune tests of the digest cache more reproducible.

COMMON OPTIONS

--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)
    Enable or disable Dune cache (either `enabled' or `disabled'). Default is `disabled'.

--cache-check-probability=VAL (absent DUNE_CACHE_CHECK_PROBABILITY env)
    Check build reproducibility by re-executing randomly chosen rules and comparing their results with those stored in Dune cache. Note: by increasing the probability of such checks you slow down the build. The default probability is zero, i.e. no rules are checked.

--cache-storage-mode=VAL (absent DUNE_CACHE_STORAGE_MODE env)
    Dune cache storage mode (one of `auto', `hardlink' or `copy'). Default is `auto'.

--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-cache=VAL
    Show debug messages on cache misses for the given cache layers. Value is a comma-separated list of cache layer names. All available cache layers: shared,workspace-local,fs.

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

--debug-digests
    Explain why Dune decides to re-digest some files

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

--debug-store-digest-preimage
    Store digest preimage for all computed digests, so that it's possible to reverse them later, for debugging. The digests are stored in the shared cache (see --cache flag) as values, even if cache is otherwise disabled. This should be used only for debugging, since it's slow and it litters the shared cache.

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

--diff-command=VAL (absent DUNE_DIFF_COMMAND env)
    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.

--dump-memo-graph=FILE
    Dumps the dependency graph to a file after the build is complete

--dump-memo-graph-format=FORMAT (absent=gexf)
    File format to be used when dumping dependency graph

--dump-memo-graph-with-timing
    With --dump-memo-graph, will re-run each cached node in the Memo graph after building and include the runtime in the output. Since all nodes contain a cached value, this will measure just the runtime of each node

--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.

--print-metrics
    Print out various performance metrics after every build

--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 --require-dune-project-file. 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.

--require-dune-project-file[=VAL] (default=true)
    Fail if a dune-project file is missing.

--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.
