NAME

6       dune-compute - Compute internal function.
7

SYNOPSIS

9       dune compute [OPTION]... FUNCTION [INPUT]
10

DESCRIPTION

12       Run a registered memoize function with the given input and print the
13       output.
14
15       This should only be used for debugging dune.
16

ARGUMENTS

18       FUNCTION (required)
19           Compute FUNCTION for a given input.
20
21       INPUT
22           Use INPUT as the input to the function.
23

OPTIONS

25       -f, --force
26           Force actions associated to aliases to be re-executed even if their
27           dependencies haven't changed.
28
29       --help[=FMT] (default=auto)
30           Show this help in format FMT. The value FMT must be one of `auto',
31           `pager', `groff' or `plain'. With `auto', the format is `pager` or
32           `plain' whenever the TERM env var is `dumb' or undefined.
33
34       --version
35           Show version information.
36
37       -w, --watch
38           Instead of terminating build after completion, wait continuously
39           for file changes.
40

COMMON OPTIONS

42       These options are common to all commands.
43
44       --auto-promote
45           Automatically promote files. This is similar to running dune
46           promote after the build.
47
48       --build-dir=FILE (absent DUNE_BUILD_DIR env)
49           Specified build directory. _build if unspecified
50
51       --config-file=FILE
52           Load this configuration file instead of the default one.
53
54       --debug-backtraces
55           Always print exception backtraces.
56
57       --debug-dependency-path
58           In case of error, print the dependency path from the targets on the
59           command line to the rule that failed.
60
61       --debug-findlib
62           Debug the findlib sub-system.
63
64       --default-target=TARGET
65           Set the default target that when none is specified to dune build.
66           It defaults to @@default.
67
68       --dev
69           Same as --profile dev
70
71       --diff-command=VAL
72           Shell command to use to diff files. Use - to disable printing the
73           diff.
74
75       --display=MODE
76           Control the display mode of Dune. See dune-config(5) for more
77           details.
78
79       --ignore-promoted-rules
80           Ignore rules with (mode promote)
81
82       -j JOBS
83           Run no more than JOBS commands simultaneously.
84
85       --no-buffer
86           Do not buffer the output of commands executed by dune. By default
87           dune buffers the output of subcommands, in order to prevent
88           interleaving when multiple commands are executed in parallel.
89           However, this can be an issue when debugging long running tests.
90           With --no-buffer, commands have direct access to the terminal. Note
91           that as a result their output won't be captured in the log file.
92           You should use this option in conjunction with -j 1, to avoid
93           interleaving. Additionally you should use --verbose as well, to
94           make sure that commands are printed before they are being executed.
95
96       --no-config
97           Do not load the configuration file
98
99       --no-print-directory
100           Suppress "Entering directory" messages
101
102       --only-packages=PACKAGES
103           Ignore stanzas referring to a package that is not in PACKAGES.
104           PACKAGES is a comma-separated list of package names. Note that this
105           has the same effect as deleting the relevant stanzas from jbuild
106           files. It is mostly meant for releases. During development, it is
107           likely that what you want instead is to build a particular
108           <package>.install target.
109
110       -p PACKAGES, --for-release-of-packages=PACKAGES
111           Shorthand for --root . --only-packages PACKAGE
112           --ignore-promoted-rules --no-config --profile release. You must use
113           this option in your <package>.opam files, in order to build only
114           what's necessary when your project contains multiple packages as
115           well as getting reproducible builds.
116
117       --profile=VAL (absent DUNE_PROFILE env)
118           Select the build profile, for instance dev or release. The default
119           is dev.
120
121       --root=DIR
122           Use this directory as workspace root instead of guessing it. Note
123           that this option doesn't change the interpretation of targets given
124           on the command line. It is only intended for scripts.
125
126       --store-orig-source-dir (absent DUNE_STORE_ORIG_SOURCE_DIR env)
127           Store original source location in dune-package metadata
128
129       --trace-file=FILE
130           Output trace data in catapult format (compatible with
131           chrome://tracing)
132
133       --verbose
134           Same as --display verbose
135
136       --workspace=FILE
137           Use this specific workspace file instead of looking it up.
138
139       -x VAL
140           Cross-compile using this toolchain.
