Dune 1.2.0

══════════

  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:

  I'd also like to personally thank him for all work he's done to make

  this release so great.



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



  Happy hacking!





1.2.0 (14/09/2018)

╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌



  • Ignore stderr output when trying to find out the number of jobs

    available (#1118, fix #1116, @diml)



  • Fix error message when the source directory of `copy_files' does not

    exist.  (#1120, fix #1099, @emillon)



  • Highlight error locations in error messages (#1121, @emillon)



  • Display actual stanza when package is ambiguous (#1126, fix #1123,

    @emillon)



  • Add `dune unstable-fmt' to format `dune' files. The interface and

    syntax are still subject to change, so use with caution. (#1130, fix

    #940, @emillon)



  • Improve error message for `dune utop' without a library name (#1154,

    fix #1149, @emillon)



  • Fix parsing `ocamllex' stanza in jbuild files (#1150, @rgrinberg)



  • Highlight multi-line errors (#1131, @anuragsoni)



  • Do no try to generate shared libraries when this is not supported by

    the OS (#1165, fix #1051, @diml)



  • Fix `Flags.write_{sexp,lines}' in configurator by avoiding the use

    of `Stdune.Path' (#1175, fix #1161, @rgrinberg)



  • Add support for `findlib.dynload': when linking an executable using

    `findlib.dynload', automatically record linked in libraries and

    findlib predicates (#1172, @bobot)



  • Add support for promoting a selected list of files (#1192, @diml)



  • Add an emacs mode providing helpers to promote correction files

    (#1192, @diml)



  • Improve message suggesting to remove parentheses (#1196, fix #1173,

    @emillon)



  • Add `(wrapped (transition "..message.."))' as an option that will

    generate wrapped modules but keep unwrapped modules with a

    deprecation message to preserve compatibility. (#1188, fix #985,

    @rgrinberg)



  • Fix the flags passed to the ppx rewriter when using `staged_pps'

    (#1218, @diml)



  • Add `(env var)' to add a dependency to an environment variable.

    (#1186, @emillon)



  • Add a simple version of a polling mode: `dune build -w' keeps

    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, #1195, @emillon)



  • Add support for private modules via the `private_modules' field

    (#1241, fix #427, @rgrinberg)



  • Add support for passing arguments to the OCaml compiler via a

    response file when the list of arguments is too long (#1256, @diml)



  • Do not print diffs by default when running inside dune (#1260,

    @diml)



  • Interpret `$ dune build dir' as building the default alias in

    `dir'. (#1259, @rgrinberg)



  • Make the `dynlink' library available without findlib installed

    (#1270, fix #1264, @rgrinberg)

    `Configurator.V1.c_test' (#1274, @rgrinberg)
