6 dune-external-lib-deps - Removed command.
7
9 dune external-lib-deps [OPTION]… [TARGET]…
10
12 This subcommand used to print out an approximate set of external
13 libraries that were required for building a given set of targets,
14 without running the build. While this feature was useful, over time the
15 quality of approximation had degraded and the cost of maintenance had
16 increased, so we decided to remove it.
17
19 --action-stderr-on-success=VAL
20 Same as --action-stdout-on-success but for the standard output for
21 error messages. A good default for large mono-repositories is
22 --action-stdout-on-success=swallow
23 --action-stderr-on-success=must-be-empty. This ensures that a
24 successful build has a "clean" empty output.
25 --action-stdout-on-success=VAL
27 Specify how to deal with the standard output of actions when they
28 succeed. Possible values are: print to just print it to Dune's
29 output, swallow to completely ignore it and must-be-empty to
30 enforce that the action printed nothing. With must-be-empty, Dune
31 will consider that the action failed if it printed something to its
32 standard output. The default is print.
33 --build-info
35 Show build information.
36 --error-reporting=VAL (absent=deterministic)
38 Controls when the build errors are reported. early - report errors
39 as soon as they are discovered. deterministic - report errors at
40 the end of the build in a deterministic order. twice - report each
41 error twice: once as soon as the error is discovered and then again
42 at the end of the build, in a deterministic order.
43 -f, --force
45 Force actions associated to aliases to be re-executed even if their
46 dependencies haven't changed.
47 --file-watcher=VAL (absent=automatic)
49 Mechanism to detect changes in the source. Automatic to make dune
50 run an external program to detect changes. Manual to notify dune
51 that files have changed manually."
52 --missing
54 unused
55 --passive-watch-mode
57 Similar to [--watch], but only start a build when instructed
58 externally by an RPC.
59 --react-to-insignificant-changes
61 react to insignificant file system changes; this is only useful for
62 benchmarking dune
63 --sandbox=VAL (absent DUNE_SANDBOX env)
65 Sandboxing mode to use by default. Some actions require a certain
66 sandboxing mode, so they will ignore this setting. The allowed
67 values are: none, symlink, copy, hardlink.
68 --sexp
70 unused
71 --unstable-by-dir
73 unused
74 -w, --watch
76 Instead of terminating build after completion, wait continuously
77 for file changes.
78 --wait-for-filesystem-clock
80 Dune digest file contents for better incrementally. These digests
81 are themselves cached. In some cases, Dune needs to drop some
82 digest cache entries in order for things to be reliable. This
83 option makes Dune wait for the file system clock to advance so that
84 it doesn't need to drop anything. You should probably not care
85 about this option; it is mostly useful for Dune developers to make
86 Dune tests of the digest cache more reproducible.
87
89 These options are common to all commands.
90 --always-show-command-line
92 Always show the full command lines of programs executed by dune
93 --auto-promote
95 Automatically promote files. This is similar to running dune
96 promote after the build.
97 --build-dir=FILE (absent DUNE_BUILD_DIR env)
99 Specified build directory. _build if unspecified
100 --cache=VAL (absent DUNE_CACHE env)
102 Enable or disable Dune cache (either enabled or disabled). Default
103 is `disabled'.
104 --cache-check-probability=VAL (absent DUNE_CACHE_CHECK_PROBABILITY env)
106 Check build reproducibility by re-executing randomly chosen rules
107 and comparing their results with those stored in Dune cache. Note:
108 by increasing the probability of such checks you slow down the
109 build. The default probability is zero, i.e. no rules are checked.
110 --cache-storage-mode=VAL (absent DUNE_CACHE_STORAGE_MODE env)
112 Dune cache storage mode (one of auto, hardlink or copy). Default is
113 `auto'.
114 --config-file=FILE
116 Load this configuration file instead of the default one.
117 --debug-artifact-substitution
119 Print debugging info about artifact substitution
120 --debug-backtraces
122 Always print exception backtraces.
123 --debug-cache=VAL
125 Show debug messages on cache misses for the given cache layers.
126 Value is a comma-separated list of cache layer names. All available
127 cache layers: shared,workspace-local,fs.
128 --debug-dependency-path
130 In case of error, print the dependency path from the targets on the
131 command line to the rule that failed.
132 --debug-digests
134 Explain why Dune decides to re-digest some files
135 --debug-findlib
137 Debug the findlib sub-system.
138 --debug-load-dir
140 Print debugging info about directory loading
141 --debug-store-digest-preimage
143 Store digest preimage for all computed digests, so that it's
144 possible to reverse them later, for debugging. The digests are
145 stored in the shared cache (see --cache flag) as values, even if
146 cache is otherwise disabled. This should be used only for
147 debugging, since it's slow and it litters the shared cache.
148 --default-target=TARGET (absent=@@default)
150 Set the default target that when none is specified to dune build.
151 --diff-command=VAL (absent DUNE_DIFF_COMMAND env)
153 Shell command to use to diff files. Use - to disable printing the
154 diff.
155 --disable-promotion (absent DUNE_DISABLE_PROMOTION env)
157 Disable all promotion rules
158 --display=MODE
160 Control the display mode of Dune. See dune-config(5) for more
161 details.
162 --dump-memo-graph=FILE
164 Dumps the dependency graph to a file after the build is complete
165 --dump-memo-graph-format=FORMAT (absent=gexf)
167 File format to be used when dumping dependency graph
168 --dump-memo-graph-with-timing
170 With --dump-memo-graph, will re-run each cached node in the Memo
171 graph after building and include the runtime in the output. Since
172 all nodes contain a cached value, this will measure just the
173 runtime of each node
174 --help[=FMT] (default=auto)
176 Show this help in format FMT. The value FMT must be one of auto,
177 pager, groff or plain. With auto, the format is pager or plain
178 whenever the TERM env var is dumb or undefined.
179 --ignore-promoted-rules
181 Ignore rules with (mode promote), except ones with (only ...). The
182 variable %{ignoring_promoted_rules} in dune files reflects whether
183 this option was passed or not.
184 --instrument-with=BACKENDS (absent DUNE_INSTRUMENT_WITH env)
186 "Enable instrumentation by BACKENDS. BACKENDS is a comma-separated
187 list of library names, each one of which must declare an
188 instrumentation backend.
189 -j JOBS
191 Run no more than JOBS commands simultaneously.
192 --no-buffer
194 Do not buffer the output of commands executed by dune. By default
195 dune buffers the output of subcommands, in order to prevent
196 interleaving when multiple commands are executed in parallel.
197 However, this can be an issue when debugging long running tests.
198 With --no-buffer, commands have direct access to the terminal. Note
199 that as a result their output won't be captured in the log file.
200 You should use this option in conjunction with -j 1, to avoid
201 interleaving. Additionally you should use --verbose as well, to
202 make sure that commands are printed before they are being executed.
203 --no-config
205 Do not load the configuration file
206 --no-print-directory
208 Suppress "Entering directory" messages
209 --only-packages=PACKAGES
211 Ignore stanzas referring to a package that is not in PACKAGES.
212 PACKAGES is a comma-separated list of package names. Note that this
213 has the same effect as deleting the relevant stanzas from dune
214 files. It is mostly meant for releases. During development, it is
215 likely that what you want instead is to build a particular
216 <package>.install target.
217 -p PACKAGES, --for-release-of-packages=PACKAGES (required)
219 Shorthand for --release --only-packages PACKAGE. You must use this
220 option in your <package>.opam files, in order to build only what's
221 necessary when your project contains multiple packages as well as
222 getting reproducible builds.
223 --print-metrics
225 Print out various performance metrics after every build
226 --profile=VAL (absent DUNE_PROFILE env)
228 Select the build profile, for instance dev or release. The default
229 is dev.
230 --promote-install-files[=VAL] (default=true)
232 Promote the generated <package>.install files to the source tree
233 --release
235 Put dune into a reproducible release mode. This is in fact a
236 shorthand for --root . --ignore-promoted-rules --no-config
237 --profile release --always-show-command-line
238 --promote-install-files --default-target @install
239 --require-dune-project-file. You should use this option for release
240 builds. For instance, you must use this option in your
241 <package>.opam files. Except if you already use -p, as -p implies
242 this option.
243 --require-dune-project-file[=VAL] (default=true)
245 Fail if a dune-project file is missing.
246 --root=DIR
248 Use this directory as workspace root instead of guessing it. Note
249 that this option doesn't change the interpretation of targets given
250 on the command line. It is only intended for scripts.
251 --store-orig-source-dir (absent DUNE_STORE_ORIG_SOURCE_DIR env)
253 Store original source location in dune-package metadata
254 --terminal-persistence=MODE
256 Changes how the log of build results are displayed to the console
257 between rebuilds while in --watch mode. Supported modes: preserve,
258 clear-on-rebuild, clear-on-rebuild-and-flush-history.
259 --trace-file=FILE
261 Output trace data in catapult format (compatible with
262 chrome://tracing)
263 --verbose
265 Same as --display verbose
266 --version
268 Show version information.
269 --workspace=FILE (absent DUNE_WORKSPACE env)
271 Use this specific workspace file instead of looking it up.
272 -x VAL
274 Cross-compile using this toolchain.
275
277 Use `dune COMMAND --help' for help on a single command.
278
280 external-lib-deps exits with the following status:
281 0 on success.
283 123 on indiscriminate errors reported on standard error.
285 124 on command line parsing errors.
287 125 on unexpected internal errors (bugs).
289
291 These environment variables affect the execution of external-lib-deps:
292 DUNE_BUILD_DIR
294 Specified build directory. _build if unspecified
295 DUNE_CACHE
297 Enable or disable Dune cache (either enabled or disabled). Default
298 is `disabled'.
299 DUNE_CACHE_CHECK_PROBABILITY
301 Check build reproducibility by re-executing randomly chosen rules
302 and comparing their results with those stored in Dune cache. Note:
303 by increasing the probability of such checks you slow down the
304 build. The default probability is zero, i.e. no rules are checked.
305 DUNE_CACHE_STORAGE_MODE
307 Dune cache storage mode (one of auto, hardlink or copy). Default is
308 `auto'.
309 DUNE_DIFF_COMMAND
311 Shell command to use to diff files. Use - to disable printing the
312 diff.
313 DUNE_DISABLE_PROMOTION
315 Disable all promotion rules
316 DUNE_INSTRUMENT_WITH
318 "Enable instrumentation by BACKENDS. BACKENDS is a comma-separated
319 list of library names, each one of which must declare an
320 instrumentation backend.
321 DUNE_PROFILE
323 Build profile. dev if unspecified or release if -p is set.
324 DUNE_SANDBOX
326 Sandboxing mode to use by default. (see --sandbox)
327 DUNE_STORE_ORIG_SOURCE_DIR
329 Store original source location in dune-package metadata
330 DUNE_WORKSPACE
332 Use this specific workspace file instead of looking it up.
