NAME

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

SYNOPSIS

10       dune top [OPTION]... [DIR]
11

DESCRIPTION

13       Print a list of toplevel directives for including directories and
14       loading cma files.
15
16       The output of dune toplevel-init-file should be evaluated in a toplevel
17       to make a library available there.
18

OPTIONS

20       --build-info
21           Show build information.
22
23       --context=CONTEXT (absent=default)
24           Select context where to build/run utop.
25
26       -f, --force
27           Force actions associated to aliases to be re-executed even if their
28           dependencies haven't changed.
29
30       --help[=FMT] (default=auto)
31           Show this help in format FMT. The value FMT must be one of `auto',
32           `pager', `groff' or `plain'. With `auto', the format is `pager` or
33           `plain' whenever the TERM env var is `dumb' or undefined.
34
35       --sandbox=VAL (absent DUNE_SANDBOX env)
36           Sandboxing mode to use by default. Some actions require a certain
37           sandboxing mode, so they will ignore this setting. The allowed
38           values are: none, symlink, copy.
39
40       --version
41           Show version information.
42
43       -w, --watch
44           Instead of terminating build after completion, wait continuously
45           for file changes.
46

COMMON OPTIONS

48       These options are common to all commands.
49
50       --always-show-command-line
51           Always show the full command lines of programs executed by dune
52
53       --auto-promote
54           Automatically promote files. This is similar to running dune
55           promote after the build.
56
57       --build-dir=FILE (absent DUNE_BUILD_DIR env)
58           Specified build directory. _build if unspecified
59
60       --cache=VAL (absent DUNE_CACHE env)
61           Activate binary cache (either `disabled' or `enabled'). Default is
62           `disabled'.
63
64       --cache-check-probability=VAL (absent=0. or
65       DUNE_CACHE_CHECK_PROBABILITY env)
66           Probability cached rules are rerun to check for reproducibility
67
68       --cache-duplication=VAL (absent DUNE_CACHE_DUPLICATION env)
69           Binary cache duplication mode
70
71       --cache-transport=VAL (absent DUNE_CACHE_TRANSPORT env)
72           Binary cache protocol
73
74       --config-file=FILE
75           Load this configuration file instead of the default one.
76
77       --debug-artifact-substitution
78           Print debugging info about artifact substitution
79
80       --debug-backtraces
81           Always print exception backtraces.
82
83       --debug-dependency-path
84           In case of error, print the dependency path from the targets on the
85           command line to the rule that failed.
86
87       --debug-findlib
88           Debug the findlib sub-system.
89
90       --default-target=TARGET (absent=@@default)
91           Set the default target that when none is specified to dune build.
92
93       --diff-command=VAL
94           Shell command to use to diff files. Use - to disable printing the
95           diff.
96
97       --disable-promotion (absent DUNE_DISABLE_PROMOTION env)
98           Disable all promotion rules
99
100       --display=MODE
101           Control the display mode of Dune. See dune-config(5) for more
102           details.
103
104       --ignore-promoted-rules
105           Ignore rules with (mode promote), except ones with (only ...). The
106           variable %{ignoring_promoted_rules} in dune files reflects whether
107           this option was passed or not.
108
109       --instrument-with=BACKENDS (absent DUNE_INSTRUMENT_WITH env)
110           "Enable instrumentation by BACKENDS. BACKENDS is a comma-separated
111           list of library names, each one of which must declare an
112           instrumentation backend.
113
114       -j JOBS
115           Run no more than JOBS commands simultaneously.
116
117       --no-buffer
118           Do not buffer the output of commands executed by dune. By default
119           dune buffers the output of subcommands, in order to prevent
120           interleaving when multiple commands are executed in parallel.
121           However, this can be an issue when debugging long running tests.
122           With --no-buffer, commands have direct access to the terminal. Note
123           that as a result their output won't be captured in the log file.
124           You should use this option in conjunction with -j 1, to avoid
125           interleaving. Additionally you should use --verbose as well, to
126           make sure that commands are printed before they are being executed.
127
128       --no-config
129           Do not load the configuration file
130
131       --no-print-directory
132           Suppress "Entering directory" messages
133
134       --only-packages=PACKAGES
135           Ignore stanzas referring to a package that is not in PACKAGES.
136           PACKAGES is a comma-separated list of package names. Note that this
137           has the same effect as deleting the relevant stanzas from dune
138           files. It is mostly meant for releases. During development, it is
139           likely that what you want instead is to build a particular
140           <package>.install target.
141
142       -p PACKAGES, --for-release-of-packages=PACKAGES
143           Shorthand for --release --only-packages PACKAGE. You must use this
144           option in your <package>.opam files, in order to build only what's
145           necessary when your project contains multiple packages as well as
146           getting reproducible builds.
147
148       --profile=VAL (absent DUNE_PROFILE env)
149           Select the build profile, for instance dev or release. The default
150           is dev.
151
152       --promote-install-files
153           Promote the generated <package>.install files to the source tree
154
155       --release
156           Put dune into a reproducible release mode. This is in fact a
157           shorthand for --root . --ignore-promoted-rules --no-config
158           --profile release --always-show-command-line
159           --promote-install-files --default-target @install. You should use
160           this option for release builds. For instance, you must use this
161           option in your <package>.opam files. Except if you already use -p,
162           as -p implies this option.
163
164       --root=DIR
165           Use this directory as workspace root instead of guessing it. Note
166           that this option doesn't change the interpretation of targets given
167           on the command line. It is only intended for scripts.
168
169       --store-orig-source-dir (absent DUNE_STORE_ORIG_SOURCE_DIR env)
170           Store original source location in dune-package metadata
171
172       --terminal-persistence=MODE
173            Changes how the log of build results are displayed to the console
174           between rebuilds while in --watch mode.
175
176       --trace-file=FILE
177           Output trace data in catapult format (compatible with
178           chrome://tracing)
179
180       --verbose
181           Same as --display verbose
182
183       --workspace=FILE (absent DUNE_WORKSPACE env)
184           Use this specific workspace file instead of looking it up.
185
186       -x VAL
187           Cross-compile using this toolchain.
