default for large mono\N'45'repositories is \fB\N'45'\N'45'action\N'45'stdout\N'45'on\N'45'success=swallow \N'45'\N'45'action\N'45'stderr\N'45'on\N'45'success=must\N'45'be\N'45'empty\fR\N'46' This ensures that a successful build has a "clean" empty output\N'46' .TP 4 \fB\N'45'\N'45'action\N'45'stdout\N'45'on\N'45'success\fR=\fIVAL\fR Specify how to deal with the standard output of actions when they succeed\N'46' Possible values are: \fBprint\fR to just print it to Dune\N'39's output, \fBswallow\fR to completely ignore it and \fBmust\N'45'be\N'45'empty\fR to enforce that the action printed nothing\N'46' With \fBmust\N'45'be\N'45'empty\fR, Dune will consider that the action failed if it printed something to its standard output\N'46' The default is \fBprint\fR\N'46' .TP 4 \fB\N'45'\N'45'build\N'45'info\fR Show build information\N'46' .TP 4 \fB\N'45'\N'45'display\N'45'separate\N'45'messages\fR Separate error messages with a blank line\N'46' .TP 4 \fB\N'45'\N'45'error\N'45'reporting\fR=\fIVAL\fR (absent=\fBdeterministic\fR) Controls when the build errors are reported\N'46' \fBearly\fR reports errors as soon as they are discovered\N'46' \fBdeterministic\fR reports errors at the end of the build in a deterministic order\N'46' \fBtwice\fR reports each error twice: once as soon as the error is discovered and then again at the end of the build, in a deterministic order\N'46' .TP 4 \fB\N'45'f\fR, \fB\N'45'\N'45'force\fR Force actions associated to aliases to be re\N'45'executed even if their dependencies haven\N'39't changed\N'46' .TP 4 \fB\N'45'\N'45'file\N'45'watcher\fR=\fIVAL\fR (absent=\fBautomatic\fR) Mechanism to detect changes in the source\N'46' Automatic to make dune run an external program to detect changes\N'46' Manual to notify dune that files have changed manually\N'46' .TP 4 \fB\N'45'\N'45'passive\N'45'watch\N'45'mode\fR Similar to [\N'45'\N'45'watch], but only start a build when instructed externally by an RPC\N'46' .TP 4 \fB\N'45'\N'45'sandbox\fR=\fIVAL\fR (absent \fBDUNE_SANDBOX\fR env) Set sandboxing mode\N'46' Some actions require a certain sandboxing mode, so they will ignore this setting\N'46' The allowed values are: none, symlink, copy, hardlink\N'46' .TP 4 \fB\N'45'\N'45'stop\N'45'on\N'45'first\N'45'error\fR Stop the build as soon as an error is encountered\N'46' .TP 4 \fB\N'45'w\fR,

contents for better incrementally\N'46' These digests are themselves cached\N'46' In some cases, Dune needs to drop some digest cache entries in order for things to be reliable\N'46' This option makes Dune wait for the file system clock to advance so that it doesn\N'39't need to drop anything\N'46' 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\N'46' .SH COMMON OPTIONS .TP 4 \fB\N'45'\N'45'always\N'45'show\N'45'command\N'45'line\fR Always show the full command lines of programs executed by dune\N'46' .TP 4 \fB\N'45'\N'45'auto\N'45'promote\fR Automatically promote files\N'46' This is similar to running \fBdune promote\fR after the build\N'46' .TP 4

\fBDUNE_CACHE_CHECK_PROBABILITY\fR env) Check build reproducibility by re\N'45'executing randomly chosen rules and comparing their results with those stored in Dune cache\N'46' Note: by increasing the probability of such checks you slow down the build\N'46' The default probability is zero, i\N'46'e\N'46' no rules are checked\N'46' .TP 4 \fB\N'45'\N'45'cache\N'45'storage\N'45'mode\fR=\fIVAL\fR

\fB\N'45'\N'45'dump\N'45'memo\N'45'graph\fR\N'46' Since all nodes contain a cached value, each measurement will only account for a single node\N'46' .TP 4 \fB\N'45'\N'45'help\fR[=\fIFMT\fR] (default=\fBauto\fR) Show this help in format \fIFMT\fR\N'46' The value \fIFMT\fR must be one of \fBauto\fR, \fBpager\fR, \fBgroff\fR or \fBplain\fR\N'46' With \fBauto\fR, the format is \fBpager\fR or

simultaneously\N'46' .TP 4 \fB\N'45'\N'45'no\N'45'buffer\fR Do not buffer the output of commands executed by dune\N'46' By default dune buffers the output of subcommands, in order to prevent interleaving when multiple commands are executed in parallel\N'46' However, this can be an issue when debugging long running tests\N'46' With \fB\N'45'\N'45'no\N'45'buffer\fR, commands have direct access to the terminal\N'46' Note that as a result their output won\N'39't be captured in the log file\N'46' You should use this option in conjunction with \fB\N'45'j 1\fR, to avoid interleaving\N'46' Additionally you should use \fB\N'45'\N'45'verbose\fR as well, to make sure that commands are printed before they are being executed\N'46' .TP 4 \fB\N'45'\N'45'no\N'45'config\fR Do not load the

to a package that is not in \fBPACKAGES\fR\N'46' \fBPACKAGES\fR is a comma\N'45'separated list of package names\N'46' Note that this has the same effect as deleting the relevant stanzas from dune
