Dune 1.6.3

dune platform

The dune team is pleased to announce the bug fix release of Dune 1.6.3. Normally, we don't bother announcing all bug fix releases, but this one contains quite a few fixes. I'd like to take this opportunity to encourage everyone to upgrade. Cheers.

See full changelog

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

  • skip directories when looking up programs in the PATH (#1628, fixes #1616, @jeremiedimino)

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

  • Do not generate targets for archive that don't match the modes field. (#1632, fix #1617, @rgrinberg)

  • When executing actions, open files lazily and close them as soon as possible in order to reduce the maximum number of file descriptors opened by Dune (#1635, #1643, fixes #1633, @jonludlam, @rgrinberg, @jeremiedimino)

  • Do not generate targets for archive that don't match the modes field. (#1632, fix #1617, @rgrinberg)

  • Get the correct environment node for multi project workspaces (#1648, @rgrinberg)

  • 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, @jeremiedimino)

Ppxlib 0.4.0

ppxlib

The ppxlib team is pleased to announce the release of ppxlib 0.4.0. This release adds better support for defining compile-time interpretation of dotted operators such as +.+ and also improves integration with other tools such as reason or metaocaml by no longer complaining about attributes generated by these tools. In particular, ppxlib now treats all attributes whose name start with an _ as machine generated attributes and doesn’t complain if it can’t decide whether they have been correctly interpreted or not. FTR, ppxlib tries to detect attributes and extension points that are dead-code, in order to catch typing mistakes or misplacement.

See full changelog
  • Do not report errors about dropped or uninterpreted attributes starting with _ (#46, fix #40, @diml)
  • Fix he special_function rule for dotted operators and allow Longident.parse to parse dotted operators (#44, @Octachron)
  • Port to dune and remove use of bash (#45, @rgrinberg)
  • Ignore all attribites starting with _ (#46, @diml)
  • Reserve the reason and refmt namespaces (#46, @diml)
  • Reserve the metaocaml namespace (#50, @rgrinberg)
  • Fix attribute extraction for Otag/Rtag (#51, @xclerc)
  • Do not relocate files unless -loc-filename is passed (#55, @hhugo)
  • Preserve the filename in the output (#56, @hhugo)

opam 2.0.2 release

opam platform

We are pleased to announce the release of opam 2.0.2.

As sandbox scripts have been updated, don't forget to run opam init --reinit -ni to update yours.

This new version contains mainly backported fixes:

  • Doc:
    • update man page
    • add message for deprecated options
    • reinsert removed ones to print a deprecated message instead of fail (e.g. --alias-of)
    • deprecate no-aspcud
  • Pin:
    • on pinning, rebuild updated pin-depends packages reliably
    • include descr & url files on pinning 1.2 opam files
  • Sandbox:
    • handle symlinks in bubblewrap for system directories such as /bin or /lib (#3661). Fixes sandboxing on some distributions such as CentOS 7 and Arch Linux.
    • allow use of unix domain sockets on macOS (#3659)
    • change one-line conditional to if statement which was incompatible with set -e
    • make /var readonly instead of empty and rw
  • Path: resolve default opam root path
  • System: suffix .out for read_command_output stdout files
  • Locked: check consistency with opam file when reading lock file to suggest regeneration message
  • Show: remove pin depends messages
  • Cudf: Fix closure computation in the presence of cycles to have a complete graph if a cycle is present in the graph (typically ocaml-base-compiler ⇄ ocaml)
  • List: Fix some cases of listing coinstallable packages
  • Format upgrade: extract archived source files of version-pinned packages
  • Core: add is_archive in OpamSystem and OpamFilename
  • Init: don't fail if empty compiler given
  • Lint: fix light_uninstall flag for error 52
  • Build: partial port to dune
  • Update cold compiler to 4.07.1

Installation instructions (unchanged):

  1. From binaries: run

    sh <(curl -sL https://opam.ocaml.org/install.sh)

    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 your 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.

Dune 1.6.0

dune platform

The dune team is pleased to announce the release of Dune 1.6.0. This release does not contain any notable features or bug fixes that need to be specifically pointed out. Nevertheless, I expect that this will be a quality of life improvement to power users who have experienced dune's sharper corners.

Happy hacking!

See full changelog

  • 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 directories used for the build. For example: (dirs :standard \ lib*) will use all directories except those that start with lib. (#1517, #1568, @rgrinberg)

  • Add binaries field to the (env ..) stanza. This field sets and overrides binaries for rules defined in a directory. (#1521, @rgrinberg)

  • Fix a crash caused by using an extension in a project without dune-project file (#1535, fix #1529, @jeremiedimino)

  • Allow %{bin:..}, %{exe:..}, and other static expansions in the deps field. (#1155, fix #1531, @rgrinberg)

  • Fix bad interaction between on-demand ppx rewriters and using multiple build contexts (#1545, @jeremiedimino)

  • Fix handling of installed .dune files when the backend is declared via a dune file (#1551, fixes #1549, @jeremiedimino)

  • Add a --stats command line option to record resource usage (#1543, @jeremiedimino)

  • Fix dune build @doc deleting highlight.pack.js on rebuilds, after the first build (#1557, @aantron).

  • Allow targets to be directories, which Dune will treat opaquely (#1547, @jordwalke)

  • Support for OCaml 4.08: List.t is now provided by OCaml (#1561, @ejgallego)

  • Exclude the local esy directory (_esy) from the list of watched directories (#1578, @andreypopp)

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

  • Introduce data_only_dirs to replace ignored_subdirs. ignored_subdirs is deprecated since 1.6. (#1590, @rgrinberg)

  • Add dune external-lib-deps --sexp --unstable-by-dir so that the output can be easily processed by a machine (#1599, @jeremiedimino)

Ocp-indent 1.7.0

ocp-indent platform
See full changelog
  • lots of small fixes
  • better handling of attributes and extension points
  • better handling of GADT definitions
  • fixed a stack-overflow on extremely large files
  • indent the same (1 step) after let f = fun x -> and let f =\n fun x ->
  • build using dune

Dune 1.5.1

dune platform
See full changelog

  • Fix dune utop <dir> when invoked from a sub-directory of the project (#1520, fix #1518, @diml)

  • Fix bad interaction between on-demand ppx rewriters and polling mode (#1525, fix #1524, @diml)

Dune 1.5.0

dune platform

On behalf of the dune team, I'm pleased to announce the 1.5.0 release of dune. This release does not contain any major features, but it does contain a few notable bug fixes and a couple of useful little additions. First of all, $ dune exec now supports C-c again - I know this affected many of you. This releases introduces a couple of new aliases that will hopefully find their way into your workflows.

The first alias is @all and has been much requested by our users. $ dune build @dir/all will build all user defined targets in a the directory dir. This would include binaries, libraries, and user defined targets in dir. This alias should have been the defaulted instead of @install when running $ dune build, but we'll have to wait until dune 2.0 to make this compatibility breaking change. In the mean time, I highly recommend everyone to use $ dune build @all instead of $ dune build meanwhile. You may also set the default alias per project as well:

(alias
 (name default)
 (deps (alias_rec all)))

The second new alias is @check. It is inspired by cargo's check subcommand and roughly corresponds to type checking the project and building all artifacts necessary for editor integration - cmt, cmti's, .merlin, etc. This is the fastest target to verify that a project is in a valid state. Note that this alias will not relink binaries so it might not catch errors such as missing stubs. I find this alias handy when doing large, type driven refactoring of a codebase.

The rest of the change log is replicated below. Happy hacking!

See full changelog

  • Filter out empty paths from OCAMLPATH and PATH (#1436, @rgrinberg)

  • Do not add the lib.cma.js target in lib's directory. Put this target in a sub directory instead. (#1435, fix #1302, @rgrinberg)

  • Install generated OCaml files with a .ml rather than a .ml-gen extension (#1425, fix #1414, @rgrinberg)

  • Allow to use the bigarray library in >= 4.07 without ocamlfind and without installing the corresponding otherlib. (#1455, @nojb)

  • Add @all alias to build all targets defined in a directory (#1409, fix #1220, @rgrinberg)

  • Add @check alias to build all targets required for type checking and tooling support. (#1447, fix #1220, @rgrinberg)

  • Produce the odoc index page with the content wrapper to make it consistent with odoc's theming (#1469, @rizo)

  • Unblock signals in processes started by dune (#1461, fixes #1451, @jeremiedimino)

  • Respect OCAMLFIND_TOOLCHAIN and add a toolchain option to contexts in the workspace file. (#1449, fix #1413, @rgrinberg)

  • Fix error message when using copy_files stanza to copy files from a non sub directory with lang set to dune < 1.3 (#1486, fixes #1485, @NathanReb)

  • Install man pages in the correct subdirectory (#1483, fixes #1441, @emillon)

  • Fix version syntax check for test stanza's action field. Only emits a warning for retro-compatibility (#1474, fixes #1471, @NathanReb)

  • Fix interpretation of paths in env stanzas (#1509, fixes #1508, @jeremiedimino)

  • Add context_name expansion variable (#1507, @rgrinberg)

  • Use shorter paths for generated on-demand ppx drivers. This is to help Windows builds where paths are limited in length (#1511, fixes #1497, @jeremiedimino)

  • Fix interpretation of environment variables under setenv. Also forbid dynamic environment names or values (#1503, @rgrinberg).

opam 2.0.1 is out!

Dune 1.4.0

dune platform

The dune team is pleased to announce the 1.4.0 release of Dune. The highlight of this release is the improved support for menhir, in particular the long awaited --infer flag. This seemingly small feature took quite a bit of coordination between the maintainers of dune and menhir. So I'd like to thank @fpottier for helping us out with this by adding better support for dune in menhir itself, and implementing the majority of the support in dune as well.

The rest of the release is mostly bug fixes, but one notable feature is that dune is now C-c friendly. Dune will now resume exactly where it's stopped after interruption instead of restarting the entire build.

EDIT: I actually forgot to mention that this release also includes integration with OCamlFormat due to @emillon. Initially, I had thought that this feature was released in 1.3.0. Sorry about that!

opam 2.0.0 release and repository upgrade

opam platform

We are happy to announce the final release of opam 2.0.0.

A few weeks ago, we released a last release candidate to be later promoted to 2.0.0, synchronised with the opam package repository upgrade.

You are encouraged to update as soon as you see fit, to continue to get package updates: opam 2.0.0 supports the older formats, and 1.2.2 will no longer get regular updates. See the Upgrade Guide for details about the new features and changes.

The website opam.ocaml.org has been updated, with the full 2.0.0 documentation pages. You can still find the documentation for the previous versions in the corresponding menu.

Package maintainers should be aware of the following:

  • the master branch of the opam package repository is now in the 2.0.0 format
  • package submissions must accordingly be made in the 2.0.0 format, or using the new version of opam-publish (2.0.0)
  • anything that was merged into the repository in 1.2 format has been automatically updated to the 2.0.0 format
  • the 1.2 format repository has been forked to its own branch, and will only be updated for critical fixes

For custom repositories, the advice remains the same.

Installation instructions (unchanged):

  1. From binaries: run

    sh <(curl -sL https://opam.ocaml.org/install.sh)

    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.

  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)

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

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

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

Dune 1.2.0

dune platform

On behalf of the dune team, I'm pleased to announce the release of Dune 1.2.0. This release contains many new goodies which I will not describe here. This is because Etienne Millon has prepared a blog post for this release: https://tarides.com/2018-09-06-dune-1-2-0.html

I'd also like to personally thank him for all work he's done to make this release so great.

Dune 1.1.0

dune platform

On behalf of the dune team, I'm proud to announce the 1.1.0 release of dune. This release contains a few interesting features that I won't describe in this post, because I've already written a dedicated blog post about this release: http://rgrinberg.com/posts/dune-upcoming-1-1/

See full changelog

  • Fix lookup of command line specified files when --root is given. Previously, passing in --root in conjunction with --workspace or --config would not work correctly (#997, @rgrinberg)

  • Add support for customizing env nodes in workspace files. The env stanza is now allowed in toplevel position in the workspace file, or for individual contexts. This feature requires (dune lang 1.1) (#1038, @rgrinberg)

  • Add enabled_if field for aliases and tests. This field controls whether the test will be ran using a boolean expression language. (#819, @rgrinberg)

  • Make name, names fields optional when a public_name, public_names field is provided. (#1041, fix #1000, @rgrinberg)

  • Interpret X in --libdir X as relative to PREFIX when X is relative (#1072, fix #1070, @jeremiedimino)

  • Add support for multi directory libraries by writing (include_subdirs unqualified) (#1034, @jeremiedimino)

  • Add (staged_pps ...) to support staged ppx rewriters such as ones using the OCaml typer like ppx_import (#1080, fix #193, @jeremiedimino)

  • Use -opaque in the dev profile. This option trades off binary quality for compilation speed when compiling .cmx files. (#1079, fix #1058, @rgrinberg)

  • Fix placeholders in dune subst documentation (#1090, @emillon, thanks @trefis for the bug report)

  • Add locations to errors when a missing binary in PATH comes from a dune file (#1096, fixes #1095, @rgrinberg)

Dune 1.0.0

dune platform

It is my pleasure to announce the 1.0.0 release of Dune!

Dune is a built system for OCaml and Reason projects. It aims at building things fast and providing a smooth user experience.

Dune 1.0.0 is now available on github and in opam.

This is a big milestone for the project as it is the first release using the new Dune name that the community helped to choose. Dune started about a year and a half ago as the more narrow scoped Jbuilder and as since then proven itself to be the right tool for the job.

A big part of the work for this release was preparing the project for long-term support. Dune is the kind of project that will pretty much continue to evolve forever: it needs to keep up with the OCaml compiler evolving, development workflows changing, new kinds of tools with specific needs, etc... While doing so, it also needs to offer stability so that projects released now will continue to build with future versions of Dune.

Meeting these two constraints is a challenge. However, we had to do this for the renaming: we changed many things in Dune using what we learned from the Jbuilder experience. Still, Dune is able to understand and build Jbuilder projects. The mechanism used to support both Jbuilder and Dune projects is fully generic and will be the basis for future evolution.

You can find the full list of changes and bug fixes since Jbuilder 1.0+beta20 on the github release page. Following is an overview of some the new features:

  • General cleanup of the syntax: less parentheses, better behaved variables

  • Introduction of a dune.configurator library to help projects with C stubs detect and query the environment

  • General improvement of the default behavior: more parallelism by default, development mode by default

  • Better support for changing the defaults: it is now possible to set the default flags or change what dune build does by default

  • Support for setting the build directory

  • Better support for expectation tests on Windows

Dune-release 0.3.0

dune-release platform

See full changelog

  • backend

    • new "polarity search" feature: provides a Hoogle-like type-based search for libraries that are in merlin's scope. See https://github.com/ocaml/merlin/blob/master/doc/features.md#polarity-search
    • new "open refactoring" feature: helps cleaning the code in the scope of an open statement. See https://github.com/ocaml/merlin/blob/master/doc/features.md#open-refactoring
    • spell-checking: a simple spell-checker has been added to suggest corrections when nothing can be directly completed.
    • type-driven record completion: merlin will now make use of type information from the context for narrowing and refining completion candidates.
    • support for #require directive in a source file, and will treat it as a package use

    • locate: various minor bugfixes, as well as the following general improvements:
      • improved context detection
      • better tracking of namespaces

      • improved support for functors: merlin will now jump through functor application to the functor definitions and in some cases go back to the argument that was given (if it is simply reexported).
    • backport fixes of OCaml 4.06.1 to the 4.06 backend
    • various minor bugfixes

  • editor modes

    • emacs
      • proper handling of multibyte strings (by @Chris00)
