Official stable release announcements and updates from the OCaml compiler, OCaml infrastructure and the OCaml Platform Tools.

Utop 2.8.0

See full changelog
  • If the current working directory is the home directory, then do not load .ocamlinit (@hyphenrf @copy #338)
  • With OCaml 4.12.0 and later, the toplevel uses the toplevel state to exit with the right status code (#348 @octachron)
  • Fix color highlight for errors (#350 @chripell)
  • Add support for OCaml 4.13 (#353 @kit-ty-kate)

Emacs mode fixes:

  • Company text-completion fixes (@leungbk #340)
  • utop-query-arguments always returns (utop-arguments) whether it sets the utop-command or not (@dansanduleac #347)
  • Fix completion returning bogus candidates (#352 @chripell @rgrinberg)

Ppxlib 0.22.1

See full changelog
  • Fix location in parse error reporting (#257, @pitag-ha)

Ppxlib 0.21.1

See full changelog
  • Fix location in parse error reporting (#256, @pitag-ha)

Mdx 1.9.0

See full changelog

Added

  • Add a new dune-gen subcommand that generates testing code for Dune to build and run with the new mdx stanza. (#305, @voodoos)
See full changelog

Fixes

  • Switch verbosity from 1 to 0. This is the same default that merlin uses. The old value for verbosity (#433)

  • Get fresh diagnostics (warning and error messages) on a file save (#438)

    Note: If you want the fresh diagnostics to take into account changes in other files, you likely need to rebuild your project. An easy way to get automatic rebuilds is to run dune in a watching mode, e.g.,[dune build --watch].

On behalf of the ocaml-lsp team, I'd like to announce version 1.6.0 of ocaml-lsp-server. The highlight of this release is the updated version of merlin which brings lots of new bug fixes.

See full changelog

Features

  • Code action to annotate a value with its type (#397)

Fixes

  • Fix interface/implementation switching on Windows (#427)

  • Correctly parse project paths with spaces and other special characters that must be escaped.

  • Print types with -short-paths even if the project wasn't built yet

See full changelog
  • merlin binary
    • external configuration reading:
      • use relative paths to communicate with Dune when possible. This solves issues related to symlinks on Unix and improve Windows support (#1271, fixes #1288)
      • make the workdir configuration value when using the dune ocaml-merlin configuration provider the same as when using dot-merlin-reader so that ppxes behaves in the same way as before (#1284, fixes ocaml/dune#4479, discussion in #1292)
    • destruct:
      • improve prefixing of generated constructors in Destruct by filtering opened modules (#1277)
      • make the destruct command more resilient to ill-typed expressions and when called without nodes (#1304, fixes #1300)
    • reintroduce some record recovery and improve completion (#1276)
    • introduce a new AST node for holes (_), allow correct typing of these holes and add a new holes command that returns the locations of all holes in the current file along with their types (#1242, #1289)
    • Mppx: don't restore cookies after invocation. Ppx are invoked only once so there is no need to manage cookies. This small change should increase performance and should not change any other behavior (#1309)
    • Windows: system command variant: do not open a window console when launching a ppx (#1270, fixes #714)
    • fix same file documentation bug (#1265 by @ulugbekna, fixes #1261)
  • editor modes
    • vim: Add MerlinNextHole and MerlinPreviousHole commands to navigate between holes. Jump to the first hole after destruct (#1287, #1303)
    • emacs: Add merlin-next-hole and merlin-previous-hole commands to navigate holes. Jump to the first hole after calling destruct. (#1291)
    • emacs: modernization of the elisp code and conformance with coding guidelines (#1247, #1310 by Steve Purcell )
    • vim & emacs : new client-side "merlin use package" commands, restoring previous behavior (#1272, fixes #1191)
  • test suite
    • cover constructor disambiguation and record fields (#1276)
    • cover the new holes command and AST node (#1242, #1289)

Installation instructions (unchanged):

  1. From binaries: run

    bash -c "sh <(curl -fsSL https://opam.ocaml.org/install.sh) --version 2.0.8"
    

    or download manually from the Github "Releases" page to your PATH. In this case, don't forget to run opam init --reinit -ni to enable sandboxing if you had version 2.0.0~rc manually installed or to update you sandbox script.

  2. From source, using opam:

    opam update; opam install opam-devel
    

    (then copy the opam binary to your PATH as explained, and don't forget to run opam init --reinit -ni to enable sandboxing if you had version 2.0.0~rc manually installed or to update you sandbox script)

  3. From source, manually: see the instructions in the README.

We hope you enjoy this new minor version, and remain open to bug reports and suggestions.

NOTE: this article is cross-posted on opam.ocaml.org and ocamlpro.com, and published in discuss.ocaml.org. Please head to the latter for the comments!

Dune 2.8.1

See full changelog
  • Fixed dune --version printing n/a rather than the version

Dune 2.8.0

On behalf of the dune, I'm pleased to announce the release of dune 2.8.0. This release contains many bug fixes, performance improvements, and interesting new features. I'll point out two new features that I'm most excited about.

First is the experimental dune_site extension that makes it possible to register and load plugins at runtime. This feature is quite involved, but we've documented it extensively in the manual.

Another cool feature is that we've eliminated the need for .merlin files and all the caveats that came with them. Now, merlin talks to dune directly to get precise configuration for every module. Say goodbye to all those "approximate .merlin file" warnings!

I encourage everyone to upgrade as soon as possible, as earlier versions are not compatible with OCaml 4.12. Happy Hacking.

See full changelog
  • 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)

  • Fix bootstrap script with custom configuration. (#3757, fixes #3774, @marsam)

  • Add the executable field to inline_tests to customize the compilation flags of the test runner executable (#3747, fixes #3679, @lubegasimon)

  • Add (enabled_if ...) to (copy_files ...) (#3756, @nojb)

  • Make sure Dune cleans up the status line before exiting (#3767, fixes #3737, @alan-j-hu)

  • Add {gitlab,bitbucket} as options for defining project sources with source stanza (source (<host> user/repo)) in the dune-project file. (#3813, @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)

  • Allow link time code generation to be used in preprocessing executable. This 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)

  • Add (root_module ..) field to libraries & executables. This makes it 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)

  • [coq] In coq.theory, :standard for the flags field now uses the flags set in env profile flags (#3931 , @ejgallego @rgrinberg)

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

  • Add support for Coq's native compute compilation mode (@ejgallego, #3210)

  • 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 longer attempt 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)

See full changelog
  • Drop Github token generation feature, no longer supported by Github API.
  • Use newer github library, avoiding warning with deprecated authentication method
  • Allow publication of packages without URL (for conf packages)
  • Added flag --no-browser to disable browser popup
  • Fix detection of package names when specifying opam file names on the command-line

On behalf of the ocaml-lsp team, it is my pleasure to announce version 1.4.0. This release introduces support for automatic signature help. Signature help is not yet present in all possible contexts. We intend to improve to support as many relevant language constructs as possible in the future. Many thanks to @mnxn for implementing this feature.

The full change log is replicated at the end of this post for your convenience.

Happy Holidays!

Dune 2.7.0

On behalf of the dune team, I'm pleased to announce the release of dune 2.7.0. This release adds a couple of important features and many bug fixes. I'll just briefly summarize the two features, and let our improved documentation elaborate on the details.

The first one is first class support for instrumentation tools such as bisect_ppx and landmarks. This is one of the most requested dune features ever, and we're pleased to show you all what we've come up with

Special thanks to @stephanieyou & @nojb for implementing this feature. Many thanks to @aantron for tirelessly iterating on the end user experience with us.

While the features is looking quite good already, we consider it a "first take" on this subject. We welcome your experience reports and feature requests.

The second feature we're introducing this release is dune's cram testing framework. The cram framework is our secret weapon for making dune (relatively) bug free. I'll soon write up a dedicated post to give you a flavour of how it works. To those who can't wait, there's a new section in the documentation that explains everything.

As always, the change log is replicated below for your convenience.

Happy Hacking.

  • 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)

  • Read Coq flags from env (#3547 , fixes #3486, @gares)

  • Allow bisect_ppx to be enabled/disabled via dune-workspace. (#3404, @stephanieyou)

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

  • Add a --debug-artifact-substution flag to help debug problem with version not being captured by dune-build-info (#3589, @jeremiedimino)

  • Allow the use of the context_name variable in the enabled_if fields of executable(s) and install stanzas. (#3568, fixes #3566, @voodoos)

  • Fix compatibility with OCaml 4.12.0 when compiling empty archives; no .a file is generated. (#3576, @dra27)

  • $ dune utop no longer tries to load optional libraries that are unavailable (#3612, fixes #3188, @anuragsoni)

  • Fix dune-build-info on 4.10.0+flambda (#3599, @emillon, @jeremiedimino).

  • Allow multiple libraries with inline_tests to be defined in the same directory (#3621, @rgrinberg)

  • Run exit hooks in jsoo separate compilation mode (#3626, fixes #3622, @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)

  • Do not allow user actions to capture dune's stdin (#3677, fixes #3672, @rgrinberg)

  • (subdir ...) stanzas can now appear in dune files used via (include ...). (#3676, @nojb)

Changes

  • Do not break inline elements such as {i blah} in docstrings (#1346, @jberdine)
  • Distinguish hash-getter from hash-comparison infix operators. Operators of the form #**# or #**. where ** can be 0 or more operator chars are considered getter operators and are not surrounded by spaces, as opposed to regular infix operators (#1376, @gpetiot)

  • Fix extra break before function body of a fun (#1343, @jberdine)
  • Indent further args of anonymous functions (#1440, @gpetiot)
  • Do not clear the emacs *compilation* buffer on successful reformat (#1350, @jberdine)
  • Fix disabling with attributes on OCaml < 4.08 (#1322, @emillon)
  • Preserve unwrapped comments by not adding artificial breaks when wrap-comments=false and ocp-indent-compat=true are set to avoid interfering with ocp-indent indentation. (#1352, @gpetiot)
  • Break long literal strings at the margin (#1367, @gpetiot)
  • Break after a multiline argument in an argument list (#1360, @gpetiot)

  • Fix placement of comments on constants (#1383, @gpetiot)
  • Do not escape arguments of some Odoc tags (#1391, 1408, @gpetiot, @Julow). The characters []{} must not be escaped in the arguments of @raise, @author, @version and others.
  • Fix missing open line between multi-line let-binding with poly-typexpr (#1372, @jberdine)
  • Remove trailing space after expression when followed by an attribute and break before attributes attached to multi-line phrases (#1382, @gpetiot)
  • Do not add a space to minimal comments (* *), (** *) and (*$ *) (#1407, @gpetiot)
  • Fix attributes position in labelled arguments type (#1434, @gpetiot)
