NAME

6       dune-printenv - Print the environment of a directory
7

SYNOPSIS

9       dune printenv [OPTION]... [PATH]
10

DESCRIPTION

12       dune printenv DIR prints the environment of a directory
13

OPTIONS

15       --build-info
16           Show build information.
17
18       -f, --force
19           Force actions associated to aliases to be re-executed even if their
20           dependencies haven't changed.
21
22       --field=FIELD
23           Only print this field. This option can be repeated multiple times
24           to print multiple fields.
25
26       --help[=FMT] (default=auto)
27           Show this help in format FMT. The value FMT must be one of `auto',
28           `pager', `groff' or `plain'. With `auto', the format is `pager` or
29           `plain' whenever the TERM env var is `dumb' or undefined.
30
31       --sandbox=VAL (absent DUNE_SANDBOX env)
32           Sandboxing mode to use by default. Some actions require a certain
33           sandboxing mode, so they will ignore this setting. The allowed
34           values are: none, symlink, copy.
35
36       --version
37           Show version information.
38
39       -w, --watch
40           Instead of terminating build after completion, wait continuously
41           for file changes.
42

COMMON OPTIONS

44       These options are common to all commands.
45
46       --always-show-command-line
47           Always show the full command lines of programs executed by dune
48
49       --auto-promote
50           Automatically promote files. This is similar to running dune
51           promote after the build.
52
53       --build-dir=FILE (absent DUNE_BUILD_DIR env)
54           Specified build directory. _build if unspecified
55
56       --cache=VAL (absent DUNE_CACHE env)
57           Activate binary cache (either `disabled' or `enabled'). Default is
58           `disabled'.
59
60       --cache-check-probability=VAL (absent=0. or
61       DUNE_CACHE_CHECK_PROBABILITY env)
62           Probability cached rules are rerun to check for reproducibility
63
64       --cache-duplication=VAL (absent DUNE_CACHE_DUPLICATION env)
65           Binary cache duplication mode
66
67       --cache-transport=VAL (absent DUNE_CACHE_TRANSPORT env)
68           Binary cache protocol
69
70       --config-file=FILE
71           Load this configuration file instead of the default one.
72
73       --debug-artifact-substitution
74           Print debugging info about artifact substitution
75
76       --debug-backtraces
77           Always print exception backtraces.
78
79       --debug-dependency-path
80           In case of error, print the dependency path from the targets on the
81           command line to the rule that failed.
82
83       --debug-findlib
84           Debug the findlib sub-system.
85
86       --default-target=TARGET (absent=@@default)
87           Set the default target that when none is specified to dune build.
88
89       --diff-command=VAL
90           Shell command to use to diff files. Use - to disable printing the
91           diff.
92
93       --disable-promotion (absent DUNE_DISABLE_PROMOTION env)
94           Disable all promotion rules
95
96       --display=MODE
97           Control the display mode of Dune. See dune-config(5) for more
98           details.
99
100       --ignore-promoted-rules
101           Ignore rules with (mode promote), except ones with (only ...). The
102           variable %{ignoring_promoted_rules} in dune files reflects whether
103           this option was passed or not.
104
105       --instrument-with=BACKENDS (absent DUNE_INSTRUMENT_WITH env)
106           "Enable instrumentation by BACKENDS. BACKENDS is a comma-separated
107           list of library names, each one of which must declare an
108           instrumentation backend.
109
110       -j JOBS
111           Run no more than JOBS commands simultaneously.
112
113       --no-buffer
114           Do not buffer the output of commands executed by dune. By default
115           dune buffers the output of subcommands, in order to prevent
116           interleaving when multiple commands are executed in parallel.
117           However, this can be an issue when debugging long running tests.
118           With --no-buffer, commands have direct access to the terminal. Note
119           that as a result their output won't be captured in the log file.
120           You should use this option in conjunction with -j 1, to avoid
121           interleaving. Additionally you should use --verbose as well, to
122           make sure that commands are printed before they are being executed.
123
124       --no-config
125           Do not load the configuration file
126
127       --no-print-directory
128           Suppress "Entering directory" messages
129
130       --only-packages=PACKAGES
131           Ignore stanzas referring to a package that is not in PACKAGES.
132           PACKAGES is a comma-separated list of package names. Note that this
133           has the same effect as deleting the relevant stanzas from dune
134           files. It is mostly meant for releases. During development, it is
135           likely that what you want instead is to build a particular
136           <package>.install target.
137
138       -p PACKAGES, --for-release-of-packages=PACKAGES
139           Shorthand for --release --only-packages PACKAGE. You must use this
140           option in your <package>.opam files, in order to build only what's
141           necessary when your project contains multiple packages as well as
142           getting reproducible builds.
143
144       --profile=VAL (absent DUNE_PROFILE env)
145           Select the build profile, for instance dev or release. The default
146           is dev.
147
148       --promote-install-files
149           Promote the generated <package>.install files to the source tree
150
151       --release
152           Put dune into a reproducible release mode. This is in fact a
153           shorthand for --root . --ignore-promoted-rules --no-config
154           --profile release --always-show-command-line
155           --promote-install-files --default-target @install. You should use
156           this option for release builds. For instance, you must use this
157           option in your <package>.opam files. Except if you already use -p,
158           as -p implies this option.
159
160       --root=DIR
161           Use this directory as workspace root instead of guessing it. Note
162           that this option doesn't change the interpretation of targets given
163           on the command line. It is only intended for scripts.
164
165       --store-orig-source-dir (absent DUNE_STORE_ORIG_SOURCE_DIR env)
166           Store original source location in dune-package metadata
167
168       --terminal-persistence=MODE
169            Changes how the log of build results are displayed to the console
170           between rebuilds while in --watch mode.
171
172       --trace-file=FILE
173           Output trace data in catapult format (compatible with
174           chrome://tracing)
175
176       --verbose
177           Same as --display verbose
178
179       --workspace=FILE (absent DUNE_WORKSPACE env)
180           Use this specific workspace file instead of looking it up.
181
182       -x VAL
183           Cross-compile using this toolchain.
