Structured concurrency library
IN THIS PACKAGE
  • Fix build on cygwin/i686-w64-mingw32 (#6008, @kit-ty-kate)

3.4.0 (20-07-2022)

  • Make dune describe correctly handle overlapping implementations
    for virtual libraries (#5971, fixes #5747, @esope)

  • Building the @check alias should make sure the libraries and executables
    don't have dependency cycles (#5892, @rgrinberg)

  • [ctypes] Add support for the errno parameter using the errno_policy field
    in the ctypes settings. (#5827, @droyo)

  • Fix dune coq top when it is invoked on files from a subdirectory of the
    directory containing the associated stanza (#5784, fixes #5552, @ejgallego,
    @rlepigre, @Alizter)

  • Fix hint when an invalid module name is found. (#5922, fixes #5273, @emillon)

  • The (cat) action now supports several files. (#5928, fixes #5795, @emillon)

  • Dune no longer uses shimmed META files for OCaml 5.x, solely using the ones
    installed by the compiler. (#5916, @dra27)

  • Fix handling of the (deps) field in (test) stanzas when there is an
    .expected file. (#5952, #5951, fixes #5950, @emillon)

  • Ignore insignificant filesystem events. This stops RPC in watch mode from
    flashing errors on insignificant file system events such as changes in the
    .git/ directory. (#5953, @rgrinberg)

  • Fix parsing more error messages emitted by the OCaml compiler. In
    particular, messages where the excerpt line number started with a blank
    character were skipped. (#5981, @rgrinberg)

  • env stanza: warn if some rules are ignored because they appear after a
    wildcard rule. (#5898, fixes #5886, @emillon)

  • On Windows, XDG_CACHE_HOME is taken to be the FOLDERID_InternetCache if
    unset, and XDG_CONFIG_HOME and XDG_DATA_HOME are both taken to be
    FOLDERID_LocalAppData if unset. (#5943, fixes #5808, @nojb)

3.3.1 (19-06-2022)

  • Improve parsing of ocamlc errors. We now correctly strip excerpts and parse
    alerts (#5879, @rgrinberg)

  • The (libraries) field of the coq.theory stanza has been renamed to
    (plugins) and the Coq language version has been bumped to 0.5.

3.3.0 (17-06-2022)

  • Sandbox preprocessing, lint, and dialect rules by default. All these rules
    now require precise dependency specifications (#5807, @rgrinberg)

  • Allow list expansion in the pps specification for preprocessing (#5820,
    @Firobe)

  • Add warnings 67-69 to dune's default set of warnings. These are warnings of
    the form "unused X.." (#5844, @rgrinbreg)

  • Introduce project "composition" for coq theories. Coq theories in separate
    projects can now refer to each other when in the same workspace (#5784,
    @Alizter, @rgrinberg)

  • Fix hint message for data_only_dirs that wrongly mentions the unknown
    constructor data_only (#5803, @lambdaxdotx)

  • Fix creating sandbox directory trees by getting rid of buggy memoization
    (@5794, @rgrinberg, @snowleopard)

  • Handle directory dependencies in sandboxed rules. Previously, the parents of
    these directory dependencies weren't created. (#5754, @rgrinberg)

  • Set the exit code to 130 when dune is terminated with a signal (#5769, fixes
    #5757)

  • Support new locations of unix, str, dynlink in OCaml >= 5.0 (#5582, @dra27)

  • The coq.theory stanza now produces rules for running coqdoc. Given a
    theory named mytheory, the directory targets mytheory.html/ and
    mytheory.tex/ or additionally the aliases @doc and @doc-latex will
    build the HTML and LaTeX documentation repsectively. (#5695, fixes #3760,
    @Alizter)

  • Coq theories marked as (boot) cannot depend on other theories
    (#5867, @ejgallego)

  • Ignore bigarray in (libraries) with OCaml >= 5.0. (#5526, fixes #5494,
    @moyodiallo)

  • Start with :standard when building the ctypes generated foreign stubs so that
    we include important compiler flags, such as -fPIC (#5816, fixes #5809).

3.2.0 (17-05-2022)

  • Fixed dune describe workspace --with-deps so that it correctly handles
    Reason files, as well as files any other dialect. (#5701, @esope)

  • Disable alerts when compiling code in vendored directories (#5683,
    @NathanReb)

  • Fixed dune describe --with-deps, that crashed when some preprocessing was
    required in a dune file using per_module. (#5682, fixes #5680, @esope)

  • Add $ dune describe pp to print the preprocssed ast of sources. (#5615,
    fixes #4470, @cannorin)

  • Report dune file evaluation errors concurrently. In the same way we report
    build errors. (#5655, @rgrinberg)

  • Watch mode now default to clearing the terminal on rebuild (#5636, fixes,
    #5216, @rgrinberg)

  • The output of jobs that finished but were cancelled is now omitted. (#5631,
    fixes #5482, @rgrinberg)

  • Allows to configure all the default destination directories with ./configure
    (adds bin, sbin, data, libexec). Use OPAM_SWITCH_PREFIX instead of
    calling the opam binaries in dune install. Fix handling of multiple
    libdir in ./configure for handling /usr/lib/ocaml/ and
    /usr/local/lib/ocaml. In dune install forbid relative directories in
    libdir, docdir and others specific directory setting because their handling
    was inconsistent (#5516, fixes #3978 and #5455, @bobot)

  • --terminal-persistence=clear-on-rebuild will no longer destroy scrollback
    on some terminals (#5646, @rgrinberg)

  • Add a fmt command as a shortcut of dune build @fmt --auto-promote (#5574,
    @tmattio)

  • Watch mode now tracks copied external files, external directories for
    dependencies, dune files in OCaml syntax, files used by include stanzas,
    dune-project, opam files, libraries builtin with compiler, and foreign
    sources (#5627, #5645, #5652, #5656, #5672, #5691, #5722, fixes #5331,
    @rgrinberg)

  • Improve metrics for cram tests. Include test names in the event and add a
    category for cram tests (#5626, @rgrinberg)

  • Allow specifying multiple licenses in project file (#5579, fixes #5574,
    @liyishuai)

  • Match glob_files only against files in external directories (#5614, fixes
    #5540, @rgrinberg)

  • Add pid's to chrome trace output (#5617, @rgrinberg)

  • Fix race when creating local cache directory (#5613, fixes #5461, @rgrinberg)

  • Add not to boolean expressions (#5610, fix #5503, @rgrinberg)

  • Fix relative dependencies outside the workspace (#4035, fixes #5572, @bobot)

  • Allow to specify --prefix via the environment variable
    DUNE_INSTALL_PREFIX (#5589, @vapourismo)

  • Dune-site.plugin: add support for archive(native|byte, plugin) used in the
    wild before findlib documented plugin(native|byte) in 2015 (#5518, @bobot)

  • Fix a bug where Dune would not correctly interpret META files in alternative
    layout (ie when the META file is named META.$pkg). The Llvm bindings were
    affected by this issue. (#5619, fixes #5616, @nojb)

  • Support (binaries) in (env) in dune-workspace files (#5560, fix #5555,
    @emillon)

  • (mdx) stanza: add support for (locks). (#5628, fixes #5489, @emillon)

  • (mdx) stanza: support including files in different directories using relative
    paths, and provide better error messages when paths are invalid (#5703, #5704,
    fixes #5596, @emillon)

  • Fix ctypes rules for external lib names which aren't valid ocaml names
    (#5667, fixes #5511, @Khady)

3.1.1 (19/04/2022)

  • Fix build on Cygwin. (#5593, fixes 5577, @nojb)

  • Fix execution of (system ..) actions on Windows. (#5593, fixes #5523,
    @nojb)

3.1.0 (15/04/2022)

  • Add sourcehut as an option for defining project sources in dune-project
    files. For example, (source (sourcehut user/repo)). (#5564, @rgrinberg)

  • Add dune coq top command for running a Coq toplevel (#5457, @rlepigre)

  • Fix dune exec dumping database in wrong directory (#5544, @bobot)

  • Always output absolute paths for locations in RPC reported diagnostics
    (#5539, @rgrinberg)

  • Add (deps <deps>) in ctype field (#5346, @bobot)

  • Add (include <file>) constructor to dependency specifications. This can be
    used to introduce dynamic dependencies (#5442, @anmonteiro)

  • Ensure that dune describe computes a transitively closed set of
    libraries (#5395, @esope)

  • Add direct dependencies to $ dune describe output (#5412, @esope)

  • Show auto-detected concurrency on Windows too (#5502, @MisterDA)

  • Fix operations that remove folders with absolute path. This happens when
    using esy (#5507, @EduardoRFS)

  • Dune will not fail if some directories are non-empty when uninstalling.
    (#5543, fixes #5542, @nojb)

  • coqdep now depends only on the filesystem layout of the .v files,
    and not on their contents (#5547, helps with #5100, @ejgallego)

  • The mdx stanza 0.2 can now be used with (implicit_transitive_deps false)
    (#5558, fixes #5499, @emillon)

  • Fix missing parenthesis in printing of corresponding terminal command for
    (with-outputs-to ) (#5551, fixes #5546, @Alizter)

  • Do not enable warnings 63-70 by default (#5476, fixes #5464, @rgrinberg)

  • Allow %{read-lines} to introduce dynamic dependencies like %{read}. (#5440,
    @anmonteiro)

  • Look up gmake before make (#5474, fixes #5470, @rgrinberg)

  • Handle empty output from getconf (#5473 fixes #5471, @mndrix)

  • Depend on any provided foreign_archives for ctypes stub generation (#5475,
    @mbacarella)

3.0.2 (17/02/2022)

  • Fix digest computation bug introduced in 3.0.1 (#5451, @rgrinberg)

3.0.1 (17/02/2022)

  • Fix compilation on MacOS SDK < 10.13. The native watch mode is disabled in
    such instances (#5431 fix #5430, @rgrinberg)

  • Do no add workspace_root to BUILD_PATH_PREFIX_MAP for projects before 3.0
    (5448, @rgrinberg)

  • Fix performance regression in incremental builds (#5439, @snowleopard)

3.0.0 (11/02/2022)

  • Remove uchar and seq dummy ocamlfind libraries from dune's builtin
    library database (#5260, @kit-ty-kate)

  • Add a DUNE_DIFF_COMMAND environment variable to match --diff-command
    command-line parameter (@raphael-proust, fix #5369, #5375)

  • Add support for odoc-link rules (#5045, @jonludlam, @lubegasimon)

  • Dune will no longer generate documentation for hidden modules (#5045,
    @jonludlam, @lubegasimon)

  • Parse the native_pack_linker field of ocamlc -config (#5281, @TheLortex)

  • Fix plugins with dot in the name (#5182, @bobot, review @rgrinberg)

  • Don't generate the dune-site build part when not needed (#4861, @bobot,
    review @kit-ty-kate)

  • Fix installation of implementations of virtual libraries (#5150, fix #3636,
    @rgrinberg)

  • Run tests in all modes defined. Previously, jsoo was excluded. (@hhugo,
    #5049, fix #4951)

  • Allow to configure the alias to run the jsoo tests (@hhugo, #5049, #4999)

  • Set jsoo compilation flags in the env stanza (@hhugo, #5049, #1613)

  • Allow to configure jsoo separate compilation in the env stanza. Previously,
    it was hard coded to always be enabled in the dev profile. (@hhugo, #5049,
    fix #970)

  • Fix build-info version in jsoo executables (@hhugo, #5049, fix #4444)

  • Pass -no-check-prims when building bytecode for jsoo (@hhugo, #5049, #4027)

  • Fix jsoo builds when dynamically linked foreign archives are disabled
    (@hhugo, #5049)

  • Disallow empty packages starting from 3.0. Empty packages may be
    re-enabled by adding the (allow_empty) to the package stanza in
    the dune-project file. (#4867, fix #2882, @kit-ty-kate, @rgrinberg)

  • Add link_flags field to the executable field of inline_tests (#5088,
    fix #1530, @jvillard)

  • In watch mode, use fsevents instead of fswatch on OSX (#4937, #4990, fixes
    #4896 @rgrinberg)

  • Remove inotifywait watch mode backend on Linux. We now use the inotify API
    exclusively (#4941, @rgrinberg)

  • Report cycles between virtual libraries and their implementation (#5050,
    fixes #2896, @rgrinberg)

  • Warn when lang versions have an ignored suffix. (lang dune 2.3.4) or (lang dune 2.3suffix) were silently parsed as 2.3 and we know suggest to remove
    the prefix. (#5040, @emillon)

  • Allow users to specify dynamic dependencies in rules. For example (deps %{read:foo.gen}) (#4662, fixes #4089, @jeremiedimino)

  • Sandbox infer rules for menhir. Fixes possible "inconsistent assumptions"
    errors (#5015, @rgrinberg)

  • Experimental support for ctypes stubs (#3905, fixes #135, @mbacarella)

  • Fix interpretation of binaries defined in the env stanza. Binaries
    defined in x/dune wouldn't be visible in `x//*/dune. (#4975, fixes #4976,
    @Leonidas-from-XIV, @rgrinberg)

  • Do not list private libraries in package listings (#4945, fixes #4799,
    @rgrinberg)

  • Allow spaces in cram test paths (#4980, fixes #4162, @rgrinberg)

  • Improve error handling of misbehaving cram scripts. (#4981, fix #4230,
    @rgrinberg)

  • Fix foreign_stubs inside a tests stanza. Previously, dune would crash
    when this field was present (#4942, fix #4946, @rgrinberg)

  • Add the enabled_if field to inline_tests within the library stanza.
    This allows us to disable executing the inline tests while still allowing for
    compilation (#4939, @rgrinberg)

  • Generate a dune-project when initializing projects with dune init proj ...
    (#4881, closes #4367, @shonfeder)

  • Allow spaces in the directory argument of the subdir stanza (#4943, fixes
    #4907, @rgrinberg)

  • Add a %{toolchain} expansion variable (#4899, fixes #3949, @rgrinberg)

  • Include dependencies of executables when creating toplevels (either dune top or dune utop) (#4882, fixes #4872, @Gopiancode)

  • Fixes opam META file requires entry for private libs (#4841, fixes #4839, @toots)

  • Allow multiple cinaps stanzas in the same directory (#4460, @rgrinberg)

  • Fix $ dune subst in empty git repositories (#4441, fixes #3619, @rgrinberg)

  • Improve interpretation of ansi escape sequence when spawning processes (#4408,
    fixes #2665, @rgrinberg)

  • Allow (package pkg) in dependencies even if pkg is an installed package
    (#4170, @bobot)

  • Allow %{version:pkg} to work for external packages (#4104, @kit-ty-kate)

  • Add (glob_files_rec <dir>/<glob>) for globbing files recursively (#4176,
    @jeremiedimino)

  • Automatically generate empty .mli files for executables and tests (#3768,
    fixes #3745, @CraigFe)

  • Add ocaml command subgroup for OCaml related commands such as utop, top,
    and merlin (#3936, @rgrinberg).

  • Detect unknown variables more eagerly (#4184, @jeremiedimino)

  • Improve location of variables and macros in error messages (#4205,
    @jeremiedimino)

  • Auto-detect dune-project files as dune files in Emacs (#4222, @shonfeder)

  • Dune no longer automatically create or edit dune-project files
    (#4239, fixes #4108, @jeremiedimino)

  • Warn if dune-project is not found (fatal in release mode) (#5343, @emillon)

  • Cleanup temporary files after running $ dune exec. (#4260, fixes #4243,
    @rgrinberg)

  • Add a new subcommand dune ocaml dump-dot-merlin that prints a mix of all the
    merlin configuration of a directory (defaulting to the current directory) in
    the Merlin configuration syntax. (#4250, @voodoos)

  • Enable cram tests by default (#4262, @rgrinberg)

  • Drop support for opam 1.x (#4280, @jeremiedimino)

  • Stop calling ocamlfind to determine the library search path or
    library installation directory. This makes the behavior of Dune
    simpler and more reproducible (#4281, @jeremiedimino)

  • Remove the external-lib-deps command. This command was only
    approximative and the cost of maintainance was getting too high. We
    removed it to make room for new more important features (#4298,
    @jeremiedimino)

  • It is now possible to define action dependencies through a chain
    of aliases. (#4303, @aalekseyev)

  • If an .ml file is not used by an executable, Dune no longer report
    parsing error in this file (#4330, @jeremiedimino)

  • Add support for sandboxing using hard links (#4360, Andrey Mokhov)

  • Fix dune crash when subdir is an absolute path (#4366, @anmonteiro)

  • Changed the implementation of actions attached to aliases, as in
    (rule (alias runtest) (action (run ./test))). A visible result for
    users is that such actions are now memoized for longer. For
    instance:

    $ echo '(rule (alias runtest) (action (echo "X=%{env:X=0}\n")))` > dune
    $ X=1 dune runtest
    X=1
    $ X=2 dune runtest
    X=2
    $ X=1 dune runtest
    

    Previously, Dune would have re-executed the action again at the last
    line. Now it remembers the result of the first execution.

  • Fix a bug where dune would always re-run all actions that produce symlinks,
    even if their dependencies did not change. (#4405, @aalekseyev)

  • Fix a bug that was causing Dune to re-hash generated files more
    often than necessary (#4419, @jeremiedimino)

  • Fields allowed in the config file are now also allowed in the
    workspace file (#4426, @jeremiedimino)

  • Add options to control how Dune should handle stdout and stderr of
    actions when then succeed. It is now possible to ask Dune to ignore
    the stdout of actions when they succeed or to request that the
    stderr of actions must be empty. This allows to reduce the noise of
    large builds (#4422, #4515, @jeremiedimino)

  • The @all alias no longer depends directly on copies of files from the source
    directory (#4461, @nojb)

  • Allow dune-file as an alternative file name for dune files (needs to be
    enabled in the dune-project file) (#4428, @nojb)

  • Drop support for upgrading jbuilder projects (#4473, @jeremiedimino)

  • Extend the environment variable BUILD_PATH_PREFIX_MAP to rewrite
    the root of the build dir (or sandbox) to /workspace_root (#4466,
    @jeremiedimino)

  • Simplify the implementation of build cache. We stop using the cache daemon to
    access the cache and instead write to and read from it directly. The new cache
    implementation is based on Jenga's cache library, which was thoroughly tested
    on large-scale builds. Using Jenga's cache library will also make it easier
    for us to port Jenga's cloud cache to Dune. (#4443, #4465, Andrey Mokhov)

  • More informative error message when Dune can't read a target that's supposed
    to be produced by the action. Old message is still produced on ENOENT, but other
    errors deserve a more detailed report. (#4501, @aalekseyev)

  • Fixed a bug where a sandboxed action would fail if it declares no dependencies in
    its initial working directory or any directory it chdirs into. (#4509, @aalekseyev)

  • Fix a crash when clearing temporary directories (#4489, #4529, Andrey Mokhov)

  • Dune now memoizes all errors when running in the file-watching mode. This
    speeds up incremental rebuilds but may be inconvenient in rare cases, e.g. if
    a build action fails due to a spurious error, such as running out of memory.
    Right now, the only way to force such actions to be rebuilt is to restart
    Dune, which clears all memoized errors. In future, we would like to provide a
    way to rerun all actions failed due to errors without restarting the build,
    e.g. via a Dune RPC call. (#4522, Andrey Mokhov)

  • Remove dune compute. It was broken and unused (#4540,
    @jeremiedimino)

  • No longer generate an approximate merlin files when computing the
    ocaml flags fails, for instance because they include the contents of
    a file that failed to build. This was a niche feature and it was
    getting in the way of making Dune's core better. (#4607, @jeremiedimino)

  • Make Dune display the progress indicator in all output modes except quiet
    (#4618, @aalekseyev)

  • Report accurate process timing information in trace mode (enabled with
    --trace-file) (#4517, @rgrinberg)

  • Do not log live_words and free_words in trace file. This allows using
    Gc.quick_stat which does not scan the heap. (#4643, @emillon)

  • Don't let command run by Dune observe the environment variable
    INSIDE_EMACS in order to improve reproducibility (#4680,
    @jeremiedimino)

  • Fix root_module when used in public libraries (#4685, fixes #4684,
    @rgrinberg, @CraigFe)

  • Fix root_module when used with preprocessing (#4683, fixes #4682,
    @rgrinberg, @CraigFe)

  • Display Coq profile flags in dune printenv (#4767, @ejgallego)

  • Introduce mdx stanza 0.2, requiring mdx >= 1.9.0, with a new generic deps
    field and the possibility to statically link libraries in the test
    executable. (#3956, #5391, fixes #3955)

  • Improve lookup of optional or disabled binaries. Previously, we'd treat every
    executable with missing libraries as optional. Now, we treat make sure to
    look at the library's optional or enabled_if status (#4786).

  • Always use 7 char hash prefix in build info version (#4857, @jberdine, fixes
    #4855)

  • Allow to explicitly disable/enable the use of dune subst by adding a
    new (subst <disable|enable>) stanza to the dune-project file.
    (#4864, @kit-ty-kate)

  • Simplify the way dune discovers the root of the workspace. It now
    stops at the first dune-workspace file it encounters, and fails if
    it finds neither a dune-workspace nor a dune-project file
    (#4921, fixes #4459, @jeremiedimino)

  • Dune no longer reads installed META files for libraries distributed with the
    compiler, instead using its own internal database. (#4946, @nojb)

  • Add support for (empty_module_interface_if_absent) in executable and library
    stanzas. (#4955, @nojb)

  • Add support for %{bin-available:...} (#4995, @jeremiedimino)

  • Make sure running git or hg in a sandboxed action, such as a
    cram test cannot escape the sandbox and pick up some random git or
    mercurial repository on the file system (#4996, @jeremiedimino)

  • Allow %{read:...} in more places such as (enabled_if ...)
    (#4994, @jeremiedimino)

  • Run each action in its own process group so that we don't leave
    stray processes behind when killing actions (#4998, @jeremiedimino)

  • Add an option expand_aliases_in_sandbox (#5003, @jeremiedimino)

  • Allow to cancel the initial scan via Control+C (#4460, fixes #4364
    @jeremiedimino)

  • Add experimental support for directory targets (#3316, #5025, Andrey Mokhov),
    enabled via (using directory-targets 0.1) in dune-project.

  • Delete old promote-into, promote-until-clean and promote-until-clean-into
    syntax (#5091, Andrey Mokhov).

  • Add link_flags in the env stanza (#5215)

  • Bootstrap: ignore errors when trying to remove generated files. (#5407,
    @damiendoligez)

2.9.4 (unreleased)

  • Do not generate META information for bigarray library in OCaml >= 5.0
    (#5421, @nojb)

  • Support new locations of unix, str, dynlink in OCaml >= 5.0
    (#5582, @dra27)

2.9.3 (26/01/2022)

  • Disable warning for deprecated Toploop functions used in dune files written in
    OCaml syntax. Restores 4.02 compatibility. (#5381, @nojb)

2.9.2 (23/01/2022)

  • Fix missing -linkall flag when linking library dune-sites.plugin
    ( #4348, @kakadu, @bobot, reported by @kakadu)

  • No longer reference deprecated Toploop functions when using dune files in
    OCaml syntax. (#4834, fixes #4830, @nojb)

  • Use the stag format API to be compatible with OCaml 5.0 (#5351, @emillon).

2.8.0 (13/01/2021)

  • dune rules accepts aliases and other non-path rules (#4063, @mrmr1993)

  • Action (diff reference test_result) now accept reference to be absent and
    in that case consider that the reference is empty. Then running dune promote
    will create the reference file. (#3795, @bobot)

  • Ignore special files (BLK, CHR, FIFO, SOCKET), (#3570, fixes #3124, #3546,
    @ejgallego)

  • Experimental: Simplify loading of additional files (data or code) at runtime
    in programs by introducing specific installation sites. In particular it allow
    to define plugins to be installed in these sites. (#3104, #3794, fixes #1185,
    @bobot)

  • Move all temporary files created by dune to run actions to a single directory
    and make sure that actions executed by dune also use this directory by setting
    TMPDIR (or TEMP on Windows). (#3691, fixes #3422, @rgrinberg)

    @rgrinberg)

  • Fix generation of META and dune-package files when some targets (byte,
    native, dynlink) are disabled. Previously, dune would generate all archives
    for regardless of settings. (#3829, #4041, @rgrinberg)

  • Do not run ocamldep to for single module executables & libraries. The
    dependency graph for such artifacts is trivial (#3847, @rgrinberg)

  • Fix cram tests inside vendored directories not being interpreted correctly.
    (#3860, fixes #3843, @rgrinberg)

  • Add package field to private libraries. This allows such libraries to be
    installed and to be usable by other public libraries in the same project
    (#3655, fixes #1017, @rgrinberg)

  • Fix the %{make} variable on Windows by only checking for a gmake binary
    on UNIX-like systems as a unrelated gmake binary might exist on Windows.
    (#3853, @kit-ty-kate)

  • Fix $ dune install modifying the build directory. This made the build
    directory unusable when $ sudo dune install modified permissions. (fix
    #3857, @rgrinberg)

  • Fix handling of aliases given on the command line (using the @ and @@
    syntax) so as to correctly handle relative paths. (#3874, fixes #3850, @nojb)

    makes it possible to use the build info module inside the preprocessor.
    (#3848, fix #3848, @rgrinberg)

  • Correctly call git ls-tree so unicode files are not quoted, this fixes
    problems with dune subst in the presence of unicode files. Fixes #3219
    (#3879, @ejgallego)

  • dune subst now accepts common command-line arguments such as
    --debug-backtraces (#3878, @ejgallego)

  • dune describe now also includes information about executables in addition to
    that of libraries. (#3892, #3895, @nojb)

  • instrumentation backends can now receive arguments via (instrumentation (backend <name> <args>)). (#3906, #3932, @nojb)

  • Tweak auto-formatting of dune files to improve readability. (#3928, @nojb)

  • Add a switch argument to opam when context is not default. (#3951, @tmattio)

  • Avoid pager when running $ git diff (#3912, @AltGr)

    possible to use library dependencies shadowed by local modules (#3825,
    @rgrinberg)

  • Allow (formatting ...) field in (env ...) stanza to set per-directory
    formatting specification. (#3942, @nojb)

    flags set in env profile flags (#3931 , @ejgallego @rgrinberg)

  • [coq] Add -q flag to :standard coqc flags , fixes #3924, (#3931 , @ejgallego)

  • Add a SUFFIX directive in .merlin files for each dialect with no
    preprocessing, to let merlin know of additional file extensions (#3977,
    @vouillon)

  • Stop promoting .merlin files. Write per-stanza Merlin configurations in
    binary form. Add a new subcommand dune ocaml-merlin that Merlin can use to
    query the configuration files. The allow_approximate_merlin option is now
    useless and deprecated. Dune now conflicts with merlin < 3.4.0 and
    ocaml-lsp-server < 1.3.0 (#3554, @voodoos)

  • Configurator: fix a bug introduced in 2.6.0 where the configurator V1 API
    doesn't work at all when used outside of dune. (#4046, @aalekseyev)

  • Fix libexec and libexec-private variables. In cross-compilation settings,
    they now point to the file in the host context. (#4058, fixes #4057,
    @TheLortex)

  • When running $ dune subst, use project metadata as a fallback when package
    metadata is missing. We also generate a warning when (name ..) is missing in
    dune-project files to avoid failures in production builds.

  • Remove support for passing -nodynlink for executables. It was bypassed in
    most cases and not correct in other cases in particular on arm32.
    (#4085, fixes #4069, fixes #2527, @emillon)

  • Generate archive rules compatible with 4.12. Dune no longer attempts to
    generate an archive file if it's unnecessary (#3973, fixes #3766, @rgrinberg)

  • Fix generated Merlin configurations when multiple preprocessors are defined
    for different modules in the same folder. (#4092, fixes #2596, #1212 and
    #3409, @voodoos)

  • Add the option use_standard_c_and_cxx_flags to dune-project that 1.
    disables the unconditional use of the ocamlc_cflags and ocamlc_cppflags
    from ocamlc -config in C compiler calls, these flags will be present in the
    :standard set instead; and 2. enables the detection of the C compiler family
    and populates the :standard set of flags with common default values when
    building CXX stubs. (#3875, #3802, fix #3718 and #3528, @voodoos)

2.7.1 (2/09/2020)

  • configurator: More flexible probing of #define. We allow duplicate values in
    the object file, as long as they are the same after parsing. (#3739, fixes
    #3736, @rgrinberg)

    #3746, @rgrinberg)

  • Resolve symlinks before running $ git diff (#3750, fixes #3740, @rgrinberg)

  • Cram tests: when checking that all test directories contain a run.t file,
    skip empty directories. These can be left around by git. (#3753, @emillon)

2.7.0 (13/08/2020)

  • Write intermediate files in a .mdx folder for each mdx stanza
    to prevent the corresponding actions to be executed as part of the @all
    alias (#3659, @NathanReb)

    landmarks, etc, via dune-workspace and/or the command-line. (#3404, #3526
    @stephanieyou, @nojb)

  • Formatting of dune files is now done in the executing dune process instead of
    in a separate process. (#3536, @nojb)

    version not being captured by dune-build-info (#3589,
    @jeremiedimino)

    @rgrinberg)

  • Add (alias ...), (mode ...) fields to (copy_fields ...) stanza (#3631, @nojb)

  • (copy_files ...) now supports copying files from outside the workspace using
    absolute file names (#3639, @nojb)

  • Dune does not use ocamlc as an intermediary to call C compiler anymore.
    Configuration flags ocamlc_cflags and ocamlc_cppflags are always prepended
    to the compiler arguments. (#3565, fixes #3346, @voodoos)

  • Revert the build optimization in #2268. This optimization slows down building
    individual executables when they're part of an executables stanza group
    (#3644, @rgrinberg)

  • Use {dev} rather than {pinned} in the generated .opam file. (#3647,
    @kit-ty-kate)

  • Insert correct extension name when editing dune-project files. Previously,
    dune would just insert the stanza name. (#3649, fixes #3624, @rgrinberg)

  • Fix crash when evaluating an mdx stanza that depends on unavailable
    packages. (#3650, @CraigFe)

  • Fix typo in cache-check-probablity field in dune config files. This field
    now requires 2.7 as it wasn't usable before this version. (#3652, @edwintorok)

  • Fix a bug where valid lib names in dune init exec --libs=lib1,lib2
    results in an error. (#3444, fix #3443, @bikallem)

  • Add and enabled_ if field to the install stanza. Enforce the same variable
    restrictions for enabled_if fields in the executable and install stanzas
    than in the library stanza. When using dune lang < 2.6, the usage of
    forbidden variables in executables stanzas with only trigger a warning to
    maintain compatibility. (#3408 and #3496, fixes #3354, @voodoos)

  • Insert a constraint one the version of dune when the user explicitly
    specify the dependency on dune in the dune-project file (#3434 ,
    fixes #3427, @diml)

  • Generate correct META files for sub-libraries (of the form lib.foo) that
    contain .js runtime files. (#3445, @hhugo)

  • Add a (no-infer ...) action that prevents inference of targets and
    dependencies in actions. (#3456, fixes #2006, @roddyyaga)

2.5.0 (09/04/2020)

  • Add a --release option meaning the same as -p but without the
    package filtering. This is useful for custom dune invocation in opam
    files where we don't want -p (#3260, @diml)

  • Fix a bug introduced in 2.4.0 causing .bc programs to be built
    with -custom by default (#3269, fixes #3262, @diml)

  • Allow contexts to be defined with local switches in workspace files (#3265,
    fix #3264, @rgrinberg)

  • Delay expansion errors until the rule is used to build something (#3261, fix

  • [coq] Support for theory dependencies and compositional builds using
    new field (theories ...) (#2053, @ejgallego, @rgrinberg)

  • From now on, each version of a syntax extension must be explicitly tied to a
    minimum version of the dune language. Inconsistent versions in a
    dune-project will trigger a warning for version <=2.4 and an error for
    versions >2.4 of the dune language. (#3270, fixes #2957, @voodoos)

  • [coq] Bump coq lang version to 0.2. New coq features presented this release
    require this version of the coq lang. (#3283, @ejgallego)

  • Prevent installation of public executables disabled using the enabled_if field.
    Installation will now simply skip such executables instead of raising an
    error. (#3195, @voodoos)

    2.0 of the dune language. (#3174, @voodoos)

  • Add a top command to integrate dune with any toplevel, not just
    utop. It is meant to be used with the new #use_output directive of
    OCaml 4.11 (#2952, @mbernat, @diml)

  • Allow per-package version in generated opam files (#3287, @toots)

  • [coq] Introduce the coq.extraction stanza. It can be used to extract OCaml
    sources (#3299, fixes #2178, @rgrinberg)

    (#3220, @snowleopard and @aalekseyev)

  • Starting from (lang dune 2.4), dune systematically puts all files
    under _build in read-only mode instead of only doing it when the
    shared cache is enabled (#3092, @mefyl)

2.3.1 (20/02/2020)

  • Fix versioning of artifact variables (eg %{cmxa:...}), which were introduced
    in 2.0, not 1.11. (#3149, @nojb)

  • Fix a bug introduced in 2.3.0 where dune insists on using fswatch on linux
    (even when inotifywait is available). (#3162, @aalekseyev)

  • Fix a bug causing all executables to be considered as optional (#3163, @diml)

2.3.0 (15/02/2020)

  • Improve validation and error handling of arguments to dune init (#3103, fixes
    #3046, @shonfeder)

  • dune init exec NAME now uses the NAME argument for private modules (#3103,
    fixes #3088, @shonfeder)

    performance when a target has a large number of dependencies (#2959,
    @ejgallego, @aalekseyev, @Armael)

  • [coq] Add (boot) option to (coq.theories) to enable bootstrap of
    Coq's stdlib (#3096, @ejgallego)

  • [coq] Deprecate public_name field in favour of package (#2087, @ejgallego)

  • Better error reporting for "data only" and "vendored" dirs. Using these with
    anything else than a strict subdirectory or * will raise an error. The
    previous behavior was to just do nothing (#3056, fixes #3019, @voodoos)

  • Fix bootstrap on bytecode only switches on windows or where -j1 is set.
    (#3112, @xclerc, @rgrinberg)

  • Allow enabled_if fields in executable(s) stanzas (#3137, fixes #1690

  • Allow to set menhir flags in the env stanza using the menhir_flags field.
    (#2960, fix #2924, @bschommer)

  • By default, do not show the full command line of commands executed
    by dune when dune is executed inside dune. This is to make
    integration tests more reproducible (#3042, @diml)

  • dune subst now works even without opam files (#2955, fixes #2910,
    @fangyi-zhou and @diml)

  • Hint when trying to execute an executable defined in the current directory
    without using the ./ prefix (#3041, fixes #1094, @voodoos).

  • Extend the list of modifiers that can be nested under
    with-accepted-exit-codes with chdir, setenv, ignore-<outputs>,
    with-stdin-from and with-<outputs>-to (#3027, fixes #3014, @voodoos)

  • It is now an error to have a preprocessing dependency on a ppx rewriter
    library that is not marked as (kind ppx_rewriter) (#3039, @snowleopard).

  • Fix permissions of files promoted to the source tree when using the
    shared cache. In particular, make them writable by the user (#3043,
    fixes #3026, @diml)

  • Only detect internal OCaml tools with .opt extensions. Previously, this
    detection applied to other binaries as well (@kit-ty-kate, @rgrinberg, #3051).

  • Give the user a proper error message when they try to promote into a source
    directory that doesn't exist. (#3073, fix #3069, @rgrinberg)

  • Correctly build vendored packages in -p mode. These packages were
    incorrectly filtered out before. (#3075, @diml)

  • Do not install vendored packages (#3074, @diml)

  • make now prints a message explaining the main targets available
    (#3085, fix #3078, @diml)

  • Add a byte_complete executable mode to build programs as
    self-contained bytecode programs
    (#3076, fixes #1519, @diml)

2.1.3 (16/01/2020)

  • Fix building the OCaml compiler with Dune (#3038, fixes #2974,
    @diml)

2.1.2 (08/01/2020)

  • Fix a bug in the Fiber.finalize function of the concurrency monad of Dune,
    causing a race condition at the user level (#3009, fix #2958, @diml)

2.1.1 (07/01/2020)

  • Guess foreign archives & native archives for libraries defined using the
    META format. (#2994, @rgrinberg, @anmonteiro)

  • Fix generation of .merlin files when depending on local libraries with more
    than one source directory. (#2983, @rgrinberg)

2.1.0 (21/12/2019)

  • Attach cinaps stanza actions to both @runtest and @cinaps aliases
    (#2831, @NathanReb)

  • Add variables %{lib-private...} and %{libexec-private...} for finding
    build paths of files in public and private libraries within the same
    project. (#2901, @snowleopard)

  • Add --mandir option to $ dune install. This option allows to override the
    installation directory for man pages. (#2915, fixes #2670, @rgrinberg)

  • Fix dune --version. The bootstrap didn't compute the version
    correctly. (#2929, fixes #2911, @diml)

  • Do not open the log file in dune clean. (#2965, fixes #2964 and
    #2921, @diml)

  • Support passing two arguments to =, <>, ... operators in package
    dependencies so that we can have things such as (<> :os win32)
    (#2965, @diml)

2.0.1 (17/12/2019)

  • Delay errors raised by invalid dune-package files. The error is now raised
    only if the invalid package is treated as a library and used to build
    something. (#2972, @rgrinberg)

2.0.0 (20/11/2019)

  • Remove existing destination files in install before installing the new
    ones. (#2885, fixes #2883, @bschommer)

  • The action field in the alias stanza is not available starting lang dune 2.0. The alias field in the rule stanza is a replacement. (#2846, fixes
    2681, @rgrinberg)

  • Introduce alias and package fields to the rule stanza. This is the
    preferred way of attaching rules to aliases. (#2744, @rgrinberg)

  • Add field (optional) for executable stanzas (#2463, fixes #2433, @bobot)

  • Infer targets for rule stanzas expressed in long form (#2494, fixes #2469,
    @NathanReb)

  • Indicate the progress of the initial file tree loading (#2459, fixes #2374,
    @bobot)

  • Build .cm[ox] files for executables more eagerly. This speeds up builds at
    the cost of building unnecessary artifacts in some cases. Some of these extra
    artifacts can fail to built, so this is a breaking change. (#2268, @rgrinberg)

  • Do not put the <package>.install files in the source tree unless -p or
    --promote-install-files is passed on the command line (#2329, @diml)

  • Compilation units of user defined executables are now mangled by default. This
    is done to prevent the accidental collision with library dependencies of the
    executable. (#2364, fixes #2292, @rgrinberg)

  • Enable (explicit_js_mode) by default. (#1941, @nojb)

  • Add an option to clear the console in-between builds with
    --terminal-persistence=clear-on-rebuild

  • Stop symlinking object files to main directory for stanzas defined jbuild
    files (#2440, @rgrinberg)

  • Library names are now validated in a strict fashion. Previously, invalid names
    would be allowed for unwrapped libraries (#2442, @rgrinberg)

  • mli only modules must now be explicitly declared. This was previously a
    warning and is now an error. (#2442, @rgrinberg)

  • Modules filtered out from the module list via the Ordered Set Language must
    now be actual modules. (#2442, @rgrinberg)

  • Actions which introduce targets where new targets are forbidden (e.g.
    preprocessing) are now an error instead of a warning. (#2442, @rgrinberg)

  • No longer install a jbuilder binary. (#2441, @diml)

  • Stub names are no longer allowed relative paths. This was previously a warning
    and is now an error (#2443, @rgrinberg).

  • Define (paths ...) fields in (context ...) definitions in order to set or
    extend any PATH-like variable in the context environment. (#2426, @nojb)

  • The diff action will always normalize newlines before diffing. Previously, it
    would not do this normalization for rules defined in jbuild files. (#2457,
    @rgrinberg)

  • Modules may no longer belong to more than one stanza. This was previously
    allowed only in stanzas defined in jbuild files. (#2458, @rgrinberg)

  • Remove support for jbuild-ignore files. They have been replaced by the the
    dirs stanza in dune files. (#2456, @rgrinberg)

  • Add a new config option sandboxing_preference, the cli argument --sandbox,
    and the dep spec sandbox in dune language. These let the user control the
    level of sandboxing done by dune per rule and globally. The rule specification
    takes precedence. The global configuration merely specifies the default.
    (#2213, @aalekseyev, @diml)

  • Remove support for old style subsystems. Dune will now emit a warning to
    reinstall the library with the old style subsystem. (#2480, @rgrinberg)

  • Add action (with-stdin-from ) to redirect input from
    when performing . (#2487, @nojb)

  • Change the automatically generated odoc index to only list public modules.
    This only affects unwrapped libraries (#2479, @rgrinberg)

  • Set up formatting rules by default. They can be configured through a new
    (formatting) stanza in dune-project (#2347, fixes #2315, @emillon)

  • Change default target from @install to @all. (#2449, fixes #1220,
    @rgrinberg)

  • Include building stubs in @check rules. (@rgrinberg, #2530)

  • Get rid of ad-hoc rules for guessing the version. Dune now only
    relies on the version written in the dune-project file and no
    longer read VERSION or similar files (#2541, @diml)

  • In (diff? x y) action, require x to exist and register a
    dependency on that file. (#2486, @aalekseyev)

  • On Windows, an .exe suffix is no longer added implicitly to binary names that
    already end in .exe. Second, when resolving binary names, .opt variants are no
    longer chosen automatically. (#2543, @nojb)

  • Make (diff? x y) move the correction file (y) away from the build
    directory to promotion staging area. This makes corrections work with
    sandboxing and in general reduces build directory pollution. (#2486,
    @aalekseyev, fixes #2482)

  • c_flags, c_names and cxx_names are now supported in executable and
    executables stanzas. (#2562, @nojb) Note: this feature has been subsequently
    extended into a separate foreign_stubs field. The fields c(xx)_names and
    c(xx)_flags are now deleted. (#2659, RFC #2650, @snowleopard)

  • Remove git integration from $ dune upgrade (#2565, @rgrinberg)

  • Add a --disable-promotion to disable all modification to the source
    directory. There's also a corresponding DUNE_DISABLE_PROMOTION environment
    variable. (#2588, fix #2568, @rgrinberg)

  • Add a forbidden_libraries field to prevent some library from being
    linked in an executable. This help detecting who accidently pulls in
    unix for instance (#2570, @diml)

  • Fix incorrect error message when a variable is expanded in static context:
    %{lib:lib:..} when the library does not exist. (#2597, fix #1541,
    @rgrinberg)

  • Add --sections option to $ dune install to install subsections of .install
    files. This is useful for installing only the binaries in a workspace for
    example. (#2609, fixes #2554, @rgrinberg)

  • Drop support for jbuild and jbuild-ignore files (#2607, @diml)

  • Add a dune-action-plugin library for describing dependencies direcly in
    the executable source. Programs that use this feature can be run by a new
    action (dynamic-run ...). (#2635, @staronj, @aalekseyev)

  • Stop installing the ocaml-syntax-shims binary. In order to use
    future_syntax, one now need to depend on the ocaml-syntax-shims
    package (#2654, @diml)

  • Add support for dependencies that are re-exported. Such dependencies
    are marked withre_export and will automatically be provided to
    users of a library (#2605, @rgrinberg)

  • Add a deprecated_library_name stanza to redirect old names after a
    library has been renamed (#2528, @diml)

  • Error out when a preprocessor_deps field is present but not
    preprocess field is. It is a warning with Dune 1.x projects
    (#2660, @Julow)

  • Dune will use -output-complete-exe instead of -custom when compiling
    self-contained bytecode executables whenever this options is available
    (OCaml version >= 4.10) (#2692, @nojb)

  • Add action (with-accepted-exit-codes <pred> <action>) to specify the set of
    successful exit codes of <action>. <pred> is specified using the predicate
    language. (#2699, @nojb)

  • Do not setup rules for disabled libraries (#2491, fixes #2272, @bobot)

  • Configurator: filter out empty flags from pkg-config (#2716, @AltGr)

  • no_keep_locs is a no-op for projects that use lang dune older than 2.0. In
    projects where the language is at least 2.0, the field is now forbidden.
    (#2752, fixes #2747, @rgrinberg)

  • Extend support for foreign sources and archives via the (foreign_library ...)
    stanza as well as the (foreign_stubs ...) and (foreign_archives ...) fields.
    (#2659, RFC #2650, @snowleopard)

  • Add (deprecated_package_names) field to (package) declaration in
    dune-project. The names declared here can be used in the (old_public_name)
    field of (deprecated_library_name) stanza. These names are interpreted as
    library names (not prefixed by a package name) and appropriate redirections are
    setup in their META files. This feature is meant to migrate old libraries which
    do not follow Dune's convention of prefixing libraries with the package
    name. (#2696, @nojb)

  • The fields license, authors, maintainers, source, bug_reports,
    homepage, and documentation of dune-project can now be overridden on a
    per-package basis. (#2774, @nojb)

  • Change the default modes field of executables to (mode exe). If
    one wants to build a bytecode program, it now needs to be explicitly
    requested via (modes byte exe). (#2851, @diml)

  • Allow ccomp_type as a variable for evaluating enabled_if. (#2855, @dra27,
    @rgrinberg)

  • Stricter validation of file names in select. The file names of conditional
    sources must match the prefix and the extension of the resultant filename.
    (#2867, @rgrinberg)

  • Add flag disable_dynamically_linked_foreign_archives to the workspace file.
    If the flag is set to true then: (i) when installing libraries, we do not
    install dynamic foreign archives dll*.so; (ii) when building executables in
    the byte mode, we statically link in foreign archives into the runtime
    system; (iii) we do not generate any dll*.so rules. (#2864, @snowleopard)

  • Reimplement the bootstrap procedure. The new procedure is faster and
    should no longer stack overflow (#2854, @dra27, @diml)

  • Allow .opam.template files to be generated using rules (#2866, @rgrinberg)

  • Delete the deprecated self_build_stubs_archive field, replaced by
    foreign_archives.

1.11.4 (09/10/2019)

  • Allow to mark directories as data_only_dirs without including them as dirs
    (#2619, fix #2584, @rgrinberg)

  • Fix reading .install files generated with an external --build-dir. (#2638,
    fix #2629, @rgrinberg)

1.11.3 (23/08/2019)

  • Fix a ppx hash collision in watch mode (#2546, fixes #2520, @diml)

1.11.2 (20/08/2019)

  • Remove the optimisation of passing -nodynlink for executables when
    not necessary. It seems to be breaking things (see #2527, @diml)

  • Fix invalid library names in dune-package files. Only public names should
    exist in such files. (#2558, fix #2425, @rgrinberg)

1.11.1 (09/08/2019)

  • Fix config file dependencies of ocamlformat (#2471, fixes #2464,
    @nojb)

  • Cleanup stale directories when using (source_tree ...) in the
    presence of directories with only sub-directories and no files
    (#2514, fixes #2499, @diml)

1.11.0 (23/07/2019)

  • Don't select all local implementations in dune utop. Instead, let the
    default implementation selection do its job. (#2327, fixes #2323, @TheLortex,
    review by @rgrinberg)

  • Check that selected implementations (either by variants or default
    implementations) are indeed implementations. (#2328, @TheLortex, review by
    @rgrinberg)

  • Don't reserve the Ppx toplevel module name for ppx rewriters (#2242, @diml)

  • Redesign of the library variant feature according to the #2134 proposal. The
    set of variants is now computed when the virtual library is installed.
    Introducing a new external_variant stanza. (#2169, fixes #2134, @TheLortex,
    review by @diml)

  • Add proper line directives when copying .cc and .cxx sources (#2275,
    @rgrinberg)

  • Fix error message for missing C++ sources. The .cc extension was always
    ignored before. (#2275, @rgrinberg)

  • Add $ dune init project subcommand to create project boilerplate according
    to a common template. (#2185, fixes #159, @shonfeder)

  • Allow to run inline tests in javascript with nodejs (#2266, @hhugo)

  • Build ppx.exe as compiling host binary. (#2286, fixes #2252, @toots, review
    by @rgrinberg and @diml)

  • Add a cinaps extension and stanza for better integration with the
    cinaps tool tool (#2269,
    @diml)

  • Allow to embed build info in executables such as version and list
    and version of statically linked libraries (#2224, @diml)

  • Set version in META and dune-package files to the one read from
    the vcs when no other version is available (#2224, @diml)

  • Add a variable %{target} to be used in situations where the context
    requires at most one word, so %{targets} can be confusing; stdout
    redirections and "-o" arguments of various tools are the main use
    case; also, introduce a separate field target that must be used
    instead of targets in those situations. (#2341, @aalekseyev)

  • Fix dependency graph of wrapped_compat modules. Previously, the dependency on
    the user written entry module was omitted. (#2305, @rgrinberg)

  • Allow to promote executables built with an executable stanza
    (#2379, @diml)

  • When instantiating an implementation with a variant, make sure it matches
    virtual library's list of known implementations. (#2361, fixes #2322,
    @TheLortex, review by @rgrinberg)

  • Add a variable %{ignoring_promoted_rules} that is true when
    --ignore-promoted-rules is passed on the command line and false
    otherwise (#2382, @diml)

  • Fix a bug in future_syntax where the characters @ and & were
    not distinguished in the names of binding operators (let@ was the
    same as let&) (#2376, @aalekseyev, @diml)

  • Workspaces with non unique project names are now supported. (#2377, fix #2325,
    @rgrinberg)

  • Improve opam generation to include the dune dependencies with the minimum
    constraint set based on the dune language version specified in the
    dune-project file. (2383, @avsm)

  • The order of fields in the generated opam file now follows order preferred in
    opam-lib. (@avsm, #2380)

  • Fix coloring of error messages from the compiler (@diml, #2384)

  • Add warning 66 to default set of warnings starting for dune projects with
    language version >= 1.11 (@rgrinberg, @diml, fixes #2299)

  • Add (dialect ...) stanza
    (@nojb, #2404)

  • Add a --context argument to dune install/uninstall (@diml, #2412)

  • Do not warn about merlin files pre 1.9. This warning can only be disabled in
    1.9 (#2421, fixes #2399, @emillon)

  • Add a new inline_tests field in the env stanza to control inline_tests
    framework with a variable (#2313, @mlasson, original idea by @diml, review
    by @rgrinberg).

  • New binary kind js for executables in order to explicitly enable Javascript
    targets, and a switch (explicit_js_mode) to require this mode in order to
    declare JS targets corresponding to executables. (#1941, @nojb)

1.10.0 (04/06/2019)

  • Restricted the set of variables available for expansion in the destination
    filename of install stanza to simplify implementation and avoid dependency
    cycles. (#2073, @aalekseyev, @diml)

  • [menhir] call menhir from context root build_dir (#2067, @ejgallego,
    review by @diml, @rgrinberg)

  • [coq] Add coq.pp stanza to help with pre-processing of grammar
    files (#2054, @ejgallego, review by @rgrinberg)

  • Add a new more generic form for the promote mode: (promote (until-clean) (into <dir>)) (#2068, @diml)

  • Allow to promote only a subset of the targets via (promote (only <pred>)). For instance: (promote (only *.mli)) (#2068, @diml)

  • Improve the behavior when a strict subset of the targets of a rule is already
    in the source tree for projects using the dune language < 1.10 (#2068, fixes
    #2061, @diml)

  • With lang dune >= 1.10, rules in standard mode are no longer allowed to
    produce targets that are present in the source tree. This has been a warning
    for long enough (#2068, @diml)

  • Allow %{...} variables in pps flags (#2076, @mlasson review by @diml and
    @aalekseyev).

  • Add a 'cookies' option to ppx_rewriter/deriver flags in library stanzas. This
    allow to specify cookie requests from variables expanded at each invocation of
    the preprocessor. (#2106, @mlasson @diml)

  • Add more opam metadata and use it to generate .opam files. In particular, a
    package field has been added to specify package specific information.
    (#2017, #2091, @avsm, @jonludlam, @rgrinberg)

  • Clean up the special support for findlib.dynload. Before, Dune would simply
    match on the library name. Now, we only match on the findlib package name when
    the library doesn't come from Dune. Someone writing a library called
    findlib.dynload with Dune would have to add (special_builtin_support findlib_dynload) to trigger the special behavior. (#2115, @diml)

  • Install the future_syntax preprocessor as ocaml-syntax-shims.exe (#2125,
    @rgrinberg)

  • Hide full command on errors and warnings in development and show them in CI.
    (detected using the CI environment variable). Commands for which the
    invocation might be omitted must output an error prefixed with File . Add an
    --always-show-command-line option to disable this behavior and always show
    the full command. (#2120, fixes #1733, @rgrinberg)

  • In dune-workspace files, add the ability to choose the host context and to
    create duplicates of the default context with different settings. (#2098,
    @TheLortex, review by @diml, @rgrinberg and @aalekseyev)

  • Add support for hg in dune subst (#2135, @diml)

  • Don't build documentation for implementations of virtual libraries (#2141,
    fixes #2138, @jonludlam)

  • Fix generation of the -pp flag in .merlin (#2142, @rgrinberg)

  • Make dune subst add a (version ...) field to the dune-project
    file (#2148, @diml)

  • Add the %{os_type} variable, which is a short-hand for
    %{ocaml-config:os_type} (#1764, @diml)

  • Allow enabled_if fields in library stanzas, restricted to the
    %{os_type}, %{model}, %{architecture}, %{system} variables (#1764,
    #2164 @diml, @rgrinberg)

  • Fix chdir on external and source paths. Dune will also fail gracefully if
    the external or source path does not exist (#2165, fixes #2158, @rgrinberg)

  • Support the .cc extension fro C++ sources (#2195, fixes #83, @rgrinberg)

  • Run ocamlformat relative to the context root. This improves the locations of
    errors. (#2196, fixes #1370, @rgrinberg)

  • Fix detection of README, LICENSE, CHANGE, and HISTORY files. These
    would be undetected whenever the project was nested in another workspace.
    (#2194, @rgrinberg)

  • Fix generation of .merlin whenever there's more than one stanza with the
    same ppx preprocessing specification (#2209 ,fixes #2206, @rgrinberg)

  • Fix generation of .merlin in the presence of the copy_files stanza and
    preprocessing specifications of other stanazs. (#2211, fixes #2206,
    @rgrinberg)

  • Run refmt from the context's root directory. This improves error messages in
    case of syntax errors. (#2223, @rgrinberg)

  • In .merlin files, don't pass -dump-ast to the future_syntax preprocessor.
    Merlin doesn't seem to like it when binary AST is generated by a -pp
    preprocessor. (#2236, @aalekseyev)

  • dune install will verify that all files mentioned in all .install files
    exist before trying to install anything. This prevents partial installation of
    packages (#2230, @rgrinberg)

1.9.3 (06/05/2019)

  • Fix .install files not being generated (#2124, fixes #2123, @rgrinberg)

1.9.2 (02/05/2019)

  • Put back library variants in development mode. We discovered a
    serious unexpected issue and we might need to adjust the design of
    this feature before we are ready to commit to a final version. Users
    will need to write (using library_variants 0.1) in their
    dune-project file if they want to use it before the design is
    finalized. (#2116, @diml)

  • Forbid to attach a variant to a library that implements a virtual
    library outside the current project (#2104, @rgrinberg)

  • Fix a bug where dune install would install man pages to incorrect
    paths when compared to opam-installer. For example dune now
    installs (foo.1 as man1/foo.1) correctly and previously that was
    installed to man1/man1/foo.1. (#2105, @aalekseyev)

  • Do not fail when a findlib directory doesn't exist (#2101, fix #2099, @diml)

  • [coq] Rename (coqlib ...) to (coq.theory ...), support for
    coqlib will be dropped in the 1.0 version of the Coq language
    (#2055, @ejgallego)

  • Fix crash when calculating library dependency closure (#2090, fixes #2085,
    @rgrinberg)

  • Clean up the special support for findlib.dynload. Before, Dune
    would simply match on the library name. Now, we only match on the
    findlib package name when the library doesn't come from
    Dune. Someone writing a library called findlib.dynload with Dune
    would have to add (special_builton_support findlib_dynload) to
    trigger the special behavior. (#2115, @diml)

  • Include permissions in the digest of targets and dependencies (#2121, fix
    #1426, @rgrinberg, @xclerc)

1.9.1 (11/04/2019)

  • Fix invocation of odoc to add previously missing include paths, impacting
    mld files that are not in directories containing libraries (#2016, fixes
    #2007, @jonludlam)

1.9.0 (09/04/2019)

  • Warn when generated .merlin does not reflect the preprocessing
    specification. This occurs when multiple stanzas in the same directory use
    different preprocessing specifications. This warning can now be disabled with
    allow_approx_merlin (#1947, fix #1946, @rgrinberg)

  • Watch mode: display "Success" in green and "Had errors" in red (#1956,
    @emillon)

  • Fix glob dependencies on installed directories (#1965, @rgrinberg)

  • Add support for library variants and default implementations. (#1900,
    @TheLortex)

  • Add experimental $ dune init command. This command is used to create or

  • Do not crash if unable to read a directory when traversing to find root
    (#2024, @rgrinberg)

  • Do not exit dune if some source directories are unreadable. Instead, warn the
    user that such directories need to be ignored (#2004, fix #310, @rgrinberg)

    binaries fields would be ignored, but instead they should be combined.
    (#2029, @rgrinberg)

    correctly erased by ^K. (#1912, @aalekseyev)

  • Add support for .cxx extension for C++ stubs (#1831, @rgrinberg)

    @diml)

1.7.2 (21/02/2019)

    #1846, @rgrinberg)

  • Configurator: Add warning to Pkg_config.query when a full package expression

    now emits a warning on every startup and both jbuilder and dune
    emit warnings when encountering jbuild files (#1752, @diml)

  • Change the layout of build artifacts inside _build. The new layout enables
    optimizations that depend on the presence of .cmx files of private modules
    (#1676, @bobot)

  • Fix merlin handling of private module visibility (#1653 @bobot)

  • unstable-fmt: use boxes to wrap some lists (#1608, fix #1153, @emillon,
    thanks to @rgrinberg)

    #1616, @diml)

  • Use lsof on macOS to implement --stats (#1636, fixes #1634, @xclerc)

    read instead of META files whenever they are available (#1329, @rgrinberg)

  • Fix preprocessing for libraries with (include_subdirs ..) (#1624, fix #1626,
    @nojb, @rgrinberg)

    @diml)

  • Reimplement the core of Dune using a new generic memoization system

    #848, @rgrinberg)

  • Let Configurator handle sizeof (in addition to negative numbers).
    (#1726, fixes #1723, @Chris00)

  • Fix an issue causing menhir generated parsers to fail to build in
    some cases. The fix is to systematically use -short-paths when
    calling ocamlc -i (#1743, fix #1504, @diml)

  • Never raise when printing located errors. The code that would print the
    location excerpts was prone to raising. (#1744, fix #1736, @rgrinberg)

    (#1749, @diml)

  • When automatically creating a dune-project file, insert the
    detected name in it (#1749, @diml)

    is turned off, transitive dependencies are not accessible. Only listed
    dependencies are directly accessible. (#1734, #430, @rgrinberg, @hnrgrgr)

  • Add toplevel stanza. This stanza is used to define toplevels with libraries
    already preloaded. (#1713, @rgrinberg)

  • Generate .merlin files that account for normal preprocessors defined using a
    subset of the action language. (#1768, @rgrinberg)

  • Emit (orig_src_dir <path>) metadata in dune-package for dune packages
    built with --store-orig-source-dir command line flag (also controlled by
    DUNE_STORE_ORIG_SOURCE_DIR env variable). This is later used to generate
    .merlin with S-directives pointed to original source locations and thus
    allowing merlin to see those. (#1750, @andreypopp)

  • Improve the behavior of dune promote when the files to be promoted have been
    deleted. (#1775, fixes #1772, @diml)

    promoted (#1783, fixes #1781, @diml)

  • unstable-fmt: ignore files using OCaml syntax (#1784, @emillon)

  • Configurator: Add which function to replace the which command line utility
    in a cross platform way. (#1773, fixes #1705, @Chris00)

  • Make configurator append paths to $PKG_CONFIG_PATH on macOS. Previously it
    was prepending paths and thus $PKG_CONFIG_PATH set by users could have been
    overridden by homebrew installed libraries (#1785, @andreypopp)

  • Disallow c/cxx sources that share an object file in the same stubs archive.
    This means that foo.c and foo.cpp can no longer exist in the same library.
    (#1788, @rgrinberg)

  • Forbid use of %{targets} (or ${@} in jbuild files) inside
    preprocessing actions
    (#1812, fixes #1811, @diml)

  • Add DUNE_PROFILE environment variable to easily set the profile. (#1806,

    @diml)

  • Rename unstable-fmt to format-dune-file and remove its --inplace option.
    (#1821, @emillon).

  • Autoformatting: (using fmt 1.1) will also format dune files (#1821, @emillon).

1.6.0 (29/11/2018)

  • Expand variables in install stanzas (#1354, @mseri)

  • Add predicate language support for specifying sub directories. This allows the
    use globs, set operations, and special values in specifying the sub

    use all directories except those that start with lib. (#1517, #1568,
    @rgrinberg)

    (#1578, @andreypopp)

  • Fix the output of dune external-lib-deps (#1594, @diml)

    (#1305, @trefis)

  • Fix bad interaction between env customization and vendored
    projects: when a vendored project didn't have its own env stanza,
    the env stanza from the enclosing project was in effect (#1408,
    @diml)

    running and restarts the build when something change on the
    filesystem (#1140, @kodek16)

  • Cleanup the way we detect the library search path. We no longer call
    opam config var lib in the default build context (#1226, @diml)

  • Make test stanzas honor the -p flag. (#1236, fix #1231, @emillon)

  • Test stanzas take an optional (action) field to customize how they run (#1248,

1.0.0 (10/07/2018)

  • Do not load the user configuration file when running inside dune
    (#700 @diml)

  • Do not infer ${null} to be a target (#693 fixes #694 @rgrinberg)

  • Introduce jbuilder.configurator library. This is a revived version of
    janestreet's configurator library with better cross compilation support, a
    versioned API, and no external dependencies. (#673, #678 #692, #695
    @rgrinberg)

  • Register the transitive dependencies of compilation units as the
    compiler might read .cm* files recursively (#666, fixes #660,
    @emillon)

  • Fix a bug causing jbuilder external-lib-deps to crash (#723,
    @diml)

  • -j now defaults to the number of processing units available rather
    4 (#726, @diml)

    executable stanza (#748, @diml)

  • Restore promoted files when they are deleted or changed in the
    source tree (#760, fix #759, @diml)

  • Fix a crash when using an invalid alias name (#762, fixes #761,
    @diml)

  • Fix a crash when using c files from another directory (#758, fixes
    #734, @diml)

  • Add an ignored_subdirs stanza to replace jbuild-ignore files
    (#767, @diml)

  • Fix a bug where Dune ignored previous occurrences of duplicated
    fields (#779, @diml)

  • Allow setting custom build directories using the --build-dir flag or
    DUNE_BUILD_DIR environment variable (#846, fix #291, @diml @rgrinberg)

  • In dune files, remove support for block (#| ... |#)) and sexp
    (#;) comments. These were very rarely used and complicate the
    language (#837, @diml)

  • In dune files, add support for block strings, allowing to nicely
    format blocks of texts (#837, @diml)

  • Remove hard-coded knowledge of ppx_driver and
    ocaml-migrate-parsetree when using a dune file (#576, @diml)

  • Make the output of Dune slightly more deterministic when run from
    inside Dune (#855, @diml)

  • Simplify quoting behavior of variables. All values are now multi-valued and
    whether a multi valued variable is allowed is determined by the quoting and
    substitution context it appears in. (#849, fix #701, @rgrinberg)

  • Fix documentation generation for private libraries. (#864, fix #856,
    @rgrinberg)

  • Use Marshal to store digest and incremental databases. This improves the
    speed of 0 rebuilds. (#817, @diml)

  • Allow setting environment variables in findlib.conf for cross compilation
    contexts. (#733, @rgrinberg)

  • Add a link_deps field to executables, to specify link-time dependencies
    like version scripts. (#879, fix #852, @emillon)

  • Rename files_recursively_in to source_tree to make it clearer it
    doesn't include generated files (#899, fix #843, @diml)

  • Present the menhir stanza as an extension with its own version
    (#901, @diml)

  • Improve the syntax of flags in (pps ...). Now instead of (pps (ppx1 -arg1 ppx2 (-foo x))) one should write (pps ppx1 -arg ppx2 -- -foo x) which looks nicer (#910, @diml)

  • Make (diff a b) ignore trailing cr on Windows and add (cmp a b) for
    comparing binary files (#904, fix #844, @diml)

  • Make dev the default build profile (#920, @diml)

  • Version dune-workspace and ~/.config/dune/config files (#932, @diml)

  • Add the ability to build an alias non-recursively from the command
    line by writing @@alias (#926, @diml)

  • Add a special default alias that defaults to (alias_rec install)
    when not defined by the user and make @@default be the default
    target (#926, @diml)

  • Forbid #require in dune files in OCaml syntax (#938, @diml)

  • Add %{profile} variable. (#938, @rgrinberg)

  • Rename path:file to dep:file (#944, @emillon)

  • Remove path-no-dep:file (#948, @emillon)

  • Adapt the behavior of dune subst for dune projects (#960, @diml)

  • Add the lib_root and libexec_root sections to install stanzas
    (#947, @diml)

  • Add a Configurator.V1.Flags module that improves the flag reading/writing
    API (#840, @avsm)

  • Add a tests stanza that simplified defining regular and expect tests
    (#822, @rgrinberg)

  • Change the subst subcommand to lookup the project name from the
    dune-project whenever it's available. (#960, @diml)

  • The subst subcommand no longer looks up the root workspace. Previously this
    detection would break the command whenever -p wasn't passed. (#960, @diml)

  • Add a # DUNE_GEN in META template files. This is done for consistency with
    # JBUILDER_GEN. (#958, @rgrinberg)

  • Rename the following variables in dune files:

    • SCOPE_ROOT to project_root

    • @ to targets

    • ^ to deps
      < was renamed in this PR and latter deleted in favor or named dependencies.
      (#957, @rgrinberg)

  • Rename ROOT to workspace_root in dune files (#993, @diml)

  • Lowercase all built-in %{variables} in dune files (#956, @rgrinberg)

  • New syntax for naming dependencies: (deps (:x a b) (:y (glob_files *.c*))).
    This replaces the use for ${<} in dune files. (#950, @diml, @rgrinberg)

  • Fix detection of dynamic cycles, which in particular may appear when
    using (package ..) dependencies (#988, @diml)

1.0+beta20 (10/04/2018)

  • Add a documentation stanza. This stanza allows one to attach .mld files to
    opam packages. (#570 @rgrinberg)

  • Execute all actions (defined using (action ..)) in the context's
    environment. (#623 @rgrinberg)

  • Add a (universe) special dependency to specify that an action depend on
    everything in the universe. Jbuilder cannot cache the result of an action that
    depend on the universe (#603, fixes #255 @diml)

  • Add a (package <package>) dependency specification to indicate dependency on
    a whole package. Rules depending on whole package will be executed in an
    environment similar to the one we get once the package is installed (#624,
    @rgrinberg and @diml)

  • Don't pass -runtime-variant _pic on Windows (#635, fixes #573 @diml)

  • Display documentation in alphabetical order. This is relevant to packages,
    libraries, and modules. (#647, fixes #606 @rgrinberg)

  • Missing asm in ocaml -config on bytecode only architecture is no longer fatal.
    The same kind of fix is preemptively applied to C compilers being absent.
    (#646, fixes $637 @rgrinberg)

  • Use the host's PATH variable when running actions during cross compilation
    (#649, fixes #625 @rgrinberg)

  • Fix incorrect include (-I) flags being passed to odoc. These flags should be
    directories that include .odoc files, rather than the include flags of the
    libraries. (#652 fixes #651 @rgrinberg)

  • Fix a regression introduced by beta19 where the generated merlin
    files didn't include the right -ppx flags in some cases (#658
    fixes #657 @diml)

  • Fix error message when a public library is defined twice. Before
    jbuilder would raise an uncaught exception (Fixes #661, @diml)

  • Fix several cases where external-lib-deps was returning too little
    dependencies (#667, fixes #644 @diml)

  • Place module list on own line in generated entry point mld (#670 @antron)

  • Cosmetic improvements to generated entry point mld (#653 @trefis)

  • Remove most useless parentheses from the syntax (#915, @diml)

1.0+beta19.1 (21/03/2018)

  • Fix regression introduced by beta19 where duplicate environment variables in
    Unix.environ would cause a fatal error. The first defined environment variable
    is now chosen. (#638 fixed by #640)

  • Use ';' as the path separator for OCAMLPATH on Cygwin (#630 fixed by #636
    @diml).

  • Use the contents of the OCAMLPATH environment variable when not relying on
    ocamlfind (#642 @diml)

1.0+beta19 (14/03/2018)

  • Ignore errors during the generation of the .merlin (#569, fixes #568 and #51)

  • Add a workaround for when a library normally installed by the
    compiler is not installed but still has a META file (#574, fixes
    #563)

  • Do not depend on ocamlfind. Instead, hard-code the library path when
    installing from opam (#575)

  • Change the default behavior regarding the check for overlaps between
    local and installed libraries. Now even if there is no link time
    conflict, we don't allow an external dependency to overlap with a
    local library, unless the user specifies allow_overlapping_dependencies
    in the jbuild file (#587, fixes #562)

  • Expose a few more variables in jbuild files: ext_obj, ext_asm,
    ext_lib, ext_dll and ext_exe as well as ${ocaml-config:XXX}
    for most variables in the output of ocamlc -config (#590)

  • Add support for inline and inline expectation tests. The system is
    generic and should support several inline test systems such as
    ppx_inline_test, ppx_expect or qtest (#547)

  • Make sure modules in the current directory always have precedence
    over included directories (#597)

  • Add support for building executables as object or shared object
    files (#23)

  • Add a best mode which is native with fallback to byte-code when
    native compilation is not available (#23)

  • Fix locations reported in error messages (#609)

  • Report error when a public library has a private dependency. Previously, this
    would be silently ignored and install broken artifacts (#607).

  • Fix display when output is not a tty (#518)

1.0+beta18.1 (14/03/2018)

  • Reduce the number of simultaneously opened fds (#578)

  • Always produce an implementation for the alias module, for
    non-jbuilder users (Fix #576)

  • Reduce interleaving in the scheduler in an attempt to make Jbuilder
    keep file descriptors open for less long (#586)

  • Accept and ignore upcoming new library fields: ppx.driver,
    inline_tests and inline_tests.backend (#588)

  • Add a hack to be able to build ppxlib, until beta20 which will have
    generic support for ppx drivers

1.0+beta18 (25/02/2018)

  • Fix generation of the implicit alias module with 4.02. With 4.02 it
    must have an implementation while with OCaml >= 4.03 it can be an
    interface only module (#549)

  • Let the parser distinguish quoted strings from atoms. This makes
    possible to use "${v}" to concatenate the list of values provided by
    a split-variable. Concatenating split-variables with text is also
    now required to be quoted.

  • Split calls to ocamldep. Before ocamldep would be called once per
    library/executables stanza. Now it is called once per file
    (#486)

  • Make sure to not pass -I <stdlib-dir> to the compiler. It is
    useless and it causes problems in some cases (#488)

  • Don't stop on the first error. Before, jbuilder would stop its
    execution after an error was encountered. Now it continues until
    all branches have been explored (#477)

  • Add support for a user configuration file (#490)

  • Add more display modes and change the default display of
    Jbuilder. The mode can be set from the command line or from the
    configuration file (#490)

  • Allow to set the concurrency level (-j N) from the configuration file (#491)

  • Store artifacts for libraries and executables in separate
    directories. This ensure that Two libraries defined in the same
    directory can't see each other unless one of them depend on the
    other (#472)

  • Better support for mli/rei only modules (#489)

  • Fix support for byte-code only architectures (#510, fixes #330)

  • Fix a regression in external-lib-deps introduced in 1.0+beta17
    (#512, fixes #485)

  • @doc alias will now build only documentation for public libraries. A new
    @doc-private alias has been added to build documentation for private
    libraries.

  • Refactor internal library management. It should now be possible to
    run jbuilder build @lint in Base for instance (#516)

  • Fix invalid warning about non-existent directory (#536, fixes #534)

1.0+beta17 (01/02/2018)

  • Make jbuilder aware that num is an external package in OCaml >= 4.06.0
    (#358)

  • jbuilder exec will now rebuild the executable before running it if
    necessary. This can be turned off by passing --no-build (#345)

  • Fix jbuilder utop to work in any working directory (#339)

  • Fix generation of META synopsis that contains double quotes (#337)

  • Add S . to .merlin by default (#284)

  • Improve jbuilder exec to make it possible to execute non public executables.
    jbuilder exec path/bin will execute bin inside default (or specified)
    context relative to path. jbuilder exec /path will execute /path as
    absolute path but with the context's environment set appropriately. Lastly,
    jbuilder exec will change the root as to which paths are relative using the
    -root option. (#286)

  • Fix jbuilder rules printing rules when some binaries are missing (#292)

  • Build documentation for non public libraries (#306)

  • Fix doc generation when several private libraries have the same name (#369)

  • Fix copy# for C/C++ with Microsoft C compiler (#353)

  • Add support for cross-compilation. Currently we are supporting the
    opam-cross-x repositories such as
    opam-cross-windows
    (#355)

  • Simplify generated META files: do not generate the transitive
    closure of dependencies in META files (#405)

  • Deprecated ${!...}: the split behavior is now a property of the
    variable. For instance ${CC}, ${^}, ${read-lines:...} all
    expand to lists unless used in the middle of a longer atom (#336)

  • Add an (include ...) stanza allowing one to include another
    non-generated jbuild file in the current file (#402)

  • Add a (diff <file1> <file2>) action allowing to diff files and
    promote generated files in case of mismatch (#402, #421)

  • Add jbuilder promote and --auto-promote to promote files (#402,
    #421)

  • Report better errors when using (glob_files ...) with a directory
    that doesn't exist (#413, Fix #412)

  • Jbuilder now properly handles correction files produced by
    ppx_driver. This allows to use [@@deriving_inline] in .ml/.mli
    files. This require ppx_driver >= v0.10.2 to work properly (#415)

  • Make jbuilder load rules lazily instead of generating them all
    eagerly. This speeds up the initial startup time of jbuilder on big
    workspaces (#370)

  • Now longer generate a META.pkg.from-jbuilder file. Now the only
    way to customize the generated META file is through
    META.pkg.template. This feature was unused and was making the code
    complicated (#370)

  • Remove read-only attribute on Windows before unlink (#247)

  • Use /Fo instead of -o when invoking the Microsoft C compiler to eliminate
    deprecation warning when compiling C++ sources (#354)

  • Add a mode field to rule stanzas:

    • (mode standard) is the default

    • (mode fallback) replaces (fallback)

    • (mode promote) means that targets are copied to the source tree
      after the rule has completed

    • (mode promote-until-clean) is the same as (mode promote) except
      that jbuilder clean deletes the files copied to the source tree.
      (#437)

  • Add a flag --ignore-promoted-rules to make jbuilder ignore rules
    with (mode promote). -p implies --ignore-promoted-rules (#437)

  • Display a warning for invalid lines in jbuild-ignore (#389)

  • Always build boot.exe as a bytecode program. It makes the build of
    jbuilder faster and fix the build on some architectures (#463, fixes #446)

  • Fix bad interaction between promotion and incremental builds on OSX
    (#460, fix #456)

  • Make the beginning of a new build more explicit in watch mode
    (#2542 @diml)

1.0+beta16 (05/11/2017)

  • Fix build on 32-bit OCaml (#313)

1.0+beta15 (04/11/2017)

  • Change the semantic of aliases: there are no longer aliases that are
    recursive such as install or runtest. All aliases are
    non-recursive. However, when requesting an alias from the command
    line, this request the construction of the alias in the specified
    directory and all its children recursively. This allows users to get
    the same behavior as previous recursive aliases for their own
    aliases, such as example. Inside jbuild files, one can use (deps (... (alias_rec xxx) ...)) to get the same behavior as on the
    command line. (#268)

  • Include sub libraries that have a . in the generated documentation index
    (#280).

  • Fix "up" links to the top-level index in the odoc generated documentation
    (#282).

  • Fix ARCH_SIXTYFOUR detection for OCaml 4.06.0 (#303)

1.0+beta14 (11/10/2017)

  • Add (copy_files ) and (copy_files# ) stanzas. These
    stanzas setup rules for copying files from a sub-directory to the
    current directory. This provides a reasonable way to support
    multi-directory library/executables in jbuilder (#35, @bobot)

  • An empty jbuild-workspace file is now interpreted the same as one
    containing just (context default)

  • Better support for on-demand utop toplevels on Windows and when the
    library has C stubs

  • Print Entering directory '...' when the workspace root is not the
    current directory. This allows Emacs and Vim to know where relative
    filenames should be interpreted from. Fixes #138

  • Fix a bug related to menhir stanzas: menhir stanzas with a
    merge_into field that were in jbuild files in sub-directories
    where incorrectly interpreted (#264)

  • Add support for locks in actions, for tests that can't be run
    concurrently (#263)

  • Support ${..} syntax in the include stanza. (#231)

1.0+beta13 (05/09/2017)

  • Generate toplevel html index for documentation (#224, @samoht)

  • Fix recompilation of native artifacts. Regression introduced in the last
    version (1.0+beta12) when digests replaces timestamps for checking staleness
    (#238, @dra27)

1.0+beta12 (18/08/2017)

  • Fix the quoting of FLG lines in generated .merlin files (#200,
    @mseri)

  • Use the full path of archive files when linking. Before jbuilder
    would do: -I <path> file.cmxa, now it does -I <path> <path>/file.cmxa. Fixes #118 and #177

  • Use an absolute path for ppx drivers in .merlin files. Merlin
    <3.0.0 used to run ppx commands from the directory where the
    .merlin was present but this is no longer the case

  • Allow to use jbuilder install in contexts other than opam; if
    ocamlfind is present in the PATH and the user didn't pass
    --prefix or --libdir explicitly, use the output of ocamlfind printconf destdir as destination directory for library files (#179,
    @bobot)

  • Allow (:include ...) forms in all *flags fields (#153, @dra27)

  • Add a utop subcommand. Running jbuilder utop in a directory
    builds and executes a custom utop toplevel with all libraries
    defined in the current directory (#183, @rgrinberg)

  • Do not accept per_file anymore in preprocess field. per_file
    was renamed per_module and it is planned to reuse per_file for
    another purpose

  • Warn when a file is both present in the source tree and generated by
    a rule. Before, jbuilder would silently ignore the rule. One now has
    to add a field (fallback) to custom rules to keep the current
    behavior (#218)

  • Get rid of the deprecated-ppx-method findlib package for ppx
    rewriters (#222, fixes #163)

  • Use digests (MD5) of files contents to detect changes rather than
    just looking at the timestamps. We still use timestamps to avoid
    recomputing digests. The performance difference is negligible and we
    avoid more useless recompilations, especially when switching branches
    for instance (#209, fixes #158)

1.0+beta11 (21/07/2017)

  • Fix the error message when there are more than one <package>.opam
    file for a given package

  • Report an error when in a wrapped library, a module that is not the
    toplevel module depends on the toplevel module. This doesn't make as
    such a module would in theory be inaccessible from the outside

  • Add ${SCOPE_ROOT} pointing to the root of the current scope, to
    fix some misuses of ${ROOT}

  • Fix useless hint when all missing dependencies are optional (#137)

  • Fix a bug preventing one from generating META.pkg.template with a
    custom rule (#190)

  • Fix compilation of reason projects: .rei files where ignored and
    caused the build to fail (#184)

1.0+beta10 (08/06/2017)

  • Add a clean subcommand (@rdavison, #89)

  • Add support for generating API documentation with odoc (#74)

  • Don't use unix in the bootstrap script, to avoid surprises with
    Cygwin

  • Improve the behavior of jbuilder exec on Windows

  • Add a --no-buffer option to see the output of commands in
    real-time. Should only be used with -j1

  • Deprecate per_file in preprocessing specifications and
    rename it per_module

  • Deprecate copy-and-add-line-directive and rename it copy#

  • Remove the ability to load arbitrary libraries in jbuild file in
    OCaml syntax. Only unix is supported since a few released packages
    are using it. The OCaml syntax might eventually be replaced by a
    simpler mechanism that plays better with incremental builds

  • Properly define and implement scopes

  • Inside user actions, ${^} now includes files matches by
    (glob_files ...) or (file_recursively_in ...)

  • When the dependencies and targets of a rule can be inferred
    automatically, you no longer need to write them: (rule (copy a b))

  • Inside (run ...), ${xxx} forms that expands to lists can now be
    split across multiple arguments by adding a !: ${!xxx}. For
    instance: (run foo ${!^})

  • Add support for using the contents of a file inside an action:

    • ${read:<file>}

    • ${read-lines:<file>}

    • ${read-strings:<file>} (same as read-lines but lines are
      escaped using OCaml convention)

  • When exiting prematurely because of a failure, if there are other
    background processes running and they fail, print these failures

  • With msvc, -lfoo is transparently replaced by foo.lib (@dra27, #127)

  • Automatically add the .exe when installing executables on Windows
    (#123)

  • (run <prog> ...) now resolves <prog> locally if
    possible. i.e. (run ${bin:prog} ...) and (run prog ...) behave
    the same. This seems like the right default

  • Fix a bug where jbuild rules would crash instead of reporting a
    proper build error

  • Fix a race condition in future.ml causing jbuilder to crash on
    Windows in some cases (#101)

  • Fix a bug causing ppx rewriter to not work properly when using
    multiple build contexts (#100)

  • Fix .merlin generation: projects in the same workspace are added to
    merlin's source path, so "locate" works on them.

1.0+beta9 (19/05/2017)

  • Add support for building Reason projects (@rgrinberg, #58)

  • Add support for building javascript with js-of-ocaml (@hhugo, #60)

  • Better support for topkg release workflow. See
    topkg-jbuilder for more
    details

  • Port the manual to rst and setup a jbuilder project on
    readthedocs.org (@rgrinberg, #78)

  • Hint for mistyped targets. Only suggest correction on the basename
    for now, otherwise it's slow when the workspace is big

  • Add a (package ...) field for aliases, so that one can restrict
    tests to a specific package (@rgrinberg, #64)

  • Fix a couple of bugs on Windows:

    • fix parsing of end of lines in some cases

    • do not take the case into account when comparing environment
      variable names

  • Add AppVeyor CI

  • Better error message in case a chain of dependencies crosses the
    installed world

  • Better error messages for invalid dependency list in jbuild files

  • Several improvements/fixes regarding the handling of findlib packages:

    • Better error messages when a findlib package is unavailable

    • Don't crash when an installed findlib package has missing
      dependencies

    • Handle the findlib alternative directory layout which is still
      used by a few packages

  • Add jbuilder installed-libraries --not-available explaining why
    some libraries are not available

  • jbuilder now records dependencies on files of external
    libraries. This mean that when you upgrade a library, jbuilder will
    know what need to be rebuilt.

  • Add a jbuilder rules subcommand to dump internal compilation
    rules, mostly for debugging purposes

  • Ignore all directories starting with a . or _. This seems to be
    a common pattern:

    • .git, .hg, _darcs

    • _build

    • _opam (opam 2 local switches)

  • Fix the hint for jbuilder external-lib-deps (#72)

  • Do not require ocamllex and ocamlyacc to be at the same location
    as ocamlc (#75)

1.0+beta8 (17/04/2017)

  • Added ${lib-available:<library-name>} which expands to true or
    false with the same semantic as literals in (select ...) stanzas

  • Remove hard-coded knowledge of a few specific ppx rewriters to ease
    maintenance moving forward

  • Pass the library name to ppx rewriters via the library-name cookie

  • Fix: make sure the action working directory exist before running it

1.0+beta7 (12/04/2017)

  • Make the output quieter by default and add a --verbose argument
    (@stedolan, #40)

  • Various documentation fixes (@adrieng, #41)

  • Make @install the default target when no targets are specified
    (@stedolan, #47)

  • Add predefined support for menhir, similar to ocamlyacc support
    (@rgrinberg, #42)

  • Add internal support for sandboxing actions and sandbox the build of
    the alias module with 4.02 to workaround the compiler trying to read
    the cmi of the aliased modules

  • Allow to disable dynlink support for libraries via (no_dynlink)
    (#55)

  • Add a -p/--for-release-of-packages command line argument to simplify
    the jbuilder invocation in opam files and make it more future proof
    (#52)

  • Fix the lookup of the executable in jbuilder exec foo. Before,
    even if foo was to be installed, the freshly built version wasn't
    selected

  • Don't generate a exists_if ... lines in META files. These are
    useless sine the META files are auto-generated

1.0+beta6 (29/03/2017)

  • Add an (executable ...) stanza for single executables (#33)

  • Add a (package ...) and (public_name <name>)/(public_names (<names)) to executable/executables stanzas to make it easier to
    install executables (#33)

  • Fix a bug when using specific rewriters that jbuilder knows about
    without ppx_driver.runner (#37). These problem should go away
    soon when we start using --cookie

  • Fix the interpretation of META files when there is more than one
    applicable assignment. Before this fix, the one with the lowest
    number of formal predicates was selected instead of the one with the
    biggest number of formal predicates

1.0+beta5 (22/03/2017)

  • When ocamlfind is present in the PATH, do not attempt to call
    opam config var lib

  • Make sure the build of jbuilder itself never calls ocamlfind or
    opam

  • Better error message when a jbuild file in OCaml syntax forgets to
    call Jbuild_plugin.V*.send

  • Added examples of use

  • Don't drop inline tests/benchmarks by default

1.0+beta4 (20/03/2017)

  • Improve error messages about invalid/missing pkg.opam files

  • Ignore all errors while running ocamlfind printconf path

1.0+beta3 (15/03/2017)

  • Print optional dependencies as optional in the output of jbuilder external-lib-deps --missing

  • Added a few forms to the DSL:

    • with-{stderr,outputs}-to

    • ignore-{stdout,stderr,outputs}

  • Added ${null} which expands to /dev/null on Unix and NUL on
    Windows

  • Improve the doc generated by odoc for wrapped libraries

  • Improve the error reported when an installed package depends on a
    library that is not installed

  • Documented (files_recursively_in ...)

  • Added black box tests

  • Fix a bug where jbuilder would crash when there was no
    <package>.opam file

  • Fixed a bug where .merlin files where not generated at the root of
    the workspace (#20)

  • Fix a bug where a (glob_files ...) would cause other dependencies
    to be ignored

  • Fix the generated ppx(...) line in META files

  • Fix (optional) when a ppx runtime dependency is not available
    (#24)

  • Do not crash when an installed package that we don't need has
    missing dependencies (#25)

1.0+beta2 (10/03/2017)

  • Simplified the rules for finding the root of the workspace as the
    old ones were often picking up the home directory. New rules are:

    • look for a jbuild-workspace file in parent directories

    • look for a jbuild-workspace* file in parent directories

    • use the current directory

  • Fixed the expansion of ${ROOT} in actions

  • Install quick-start.org in the documentation directory

  • Add a few more things in the log file to help debugging

1.0+beta1 (07/03/2017)

  • Added a manual

  • Support incremental compilation

  • Switched the CLI to cmdliner and added a build command (#5, @rgrinberg)

  • Added a few commands:

    • runtest

    • install

    • uninstall

    • installed-libraries

    • exec: execute a command in an environment similar to what you
      would get after jbuilder install

  • Removed the build-package command in favor of a --only-packages
    option that is common to all commands

  • Automatically generate .merlin files (#2, @rdavison)

  • Improve the output of jbuilder, in particular don't mangle the
    output of commands when using -j N with N > 1

  • Generate a log in _build/log

  • Versioned the jbuild format and added a first stable version. You
    should now put (jbuilder_version 1) in a jbuild file at the root
    of your project to ensure forward compatibility

  • Switch from ppx_driver to ocaml-migrate-parsetree.driver. In
    order to use ppx rewriters with Jbuilder, they need to use
    ocaml-migrate-parsetree.driver

  • Added support for aliases (#7, @rgrinberg)

  • Added support for compiling against multiple opam switch
    simultaneously by writing a jbuild-workspace file

  • Added support for OCaml 4.02.3

  • Added support for architectures that don't have natdynlink

  • Search the root according to the rules described in the manual
    instead of always using the current directory

  • extended the action language to support common actions without using
    a shell:

    • (with-stdout-to <file> <DSL>)

    • (copy <src> <dst>)

    • ...

  • Removed all implicit uses of bash or the system shell. Now one has
    to write explicitly (bash "...") or (system "...")

  • Generate meaningful versions in META files

  • Strengthen the scope of a package. Jbuilder knows about package
    foo only in the sub-tree starting from where foo.opam lives

0.1.alpha1 (04/12/2016)
