OCaml Changelog

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

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

• Remove assert false in favor of error message. (#125, @ejgallego)
• Embed a 'version: "$release-version"' in each opam file of the current directory to get reproducible releases (#128, #129, @hannesm)
• Generate sha256 and sha512 checksums for release (#131, @hannesm)
• Grammar fixes (#132, @anmonteiro)
• Handle doc fields with no trailing slash (#133, @yomimono)

• 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 update project boilerplate. (#1448, fixes #159, @shonfeder)

• Experimental Coq support (fix #1466, @ejgallego)

• Install .cmi files of private modules in a .private directory (#1983, fix #1973 @rgrinberg)

• Fix dune subst attempting to substitute on directories. (#2000, fix #1997, @rgrinberg)

• Do not list private modules in the generated index. (#2009, fix #2008, @rgrinberg)

• Warn instead of failing if an opam file fails to parse. This opam file can still be used to define scope. (#2023, @rgrinberg)

• 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)

• Fix nested (binaries ..) fields in the env stanza. Previously, parent binaries fields would be ignored, but instead they should be combined. (#2029, @rgrinberg)

• Allow "." in c_names and cxx_names (#2036, fix #2033, @rgrinberg)

• Format rules: if a dune file uses OCaml syntax, do not format it. (#2014, fix #2012, @emillon)

• Improve error message when dune subst fails (#1898, fix #1897, @rgrinberg)

• Add more GC counters to catapult traces (fix908, @rgrinberg)

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

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

• 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)

• Add virtual libraries feature and enable it by default (#1430 fixes #921, @rgrinberg)

• Fix handling of Control+C in watch mode (#1678, fixes #1671, @jeremiedimino)

• Make the seq package available for OCaml >= 4.07 (#1714, @rgrinberg)

• Add locations to error messages where a rule fails to generate targets and rules that require files outside the build/source directory. (#1708, fixes #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, @jeremiedimino)

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

• Add a dune upgrade command for upgrading jbuilder projects to Dune (#1749, @jeremiedimino)

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

• 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, @jeremiedimino)

• unstable-fmt: preserve comments (#1766, @emillon)

• Pass flags correctly when using staged_pps (#1779, fixes #1774, @jeremiedimino)

• Fix an issue with the use of (mode promote) in the menhir stanza. It was previously causing intermediate mock files to be promoted (#1783, fixes #1781, @jeremiedimino)

• 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, @jeremiedimino)

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