OCaml Changelog

• backend
  • catch findlib initialization failures and keep going on

• Add --force-output option to force generation of diff file (#118 @clecat)
• Support OCaml 4.08.0 (#121 @xclerc)
• README and documentation fixes (#122 #118 @andreypopp @clecat @samoht)
• Use latest ocaml-migrate-parsetree interfaces (@avsm)

• Fix a bug in documentation publication where under certain circumstances the doc would be published in a _html folder instead of being published at the root of gh-pages (#157, @NathanReb)

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

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

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

• 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, @jeremiedimino)

• 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, @jeremiedimino)

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

• 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, @jeremiedimino)

• 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 @jeremiedimino, @rgrinberg and @aalekseyev)

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

• 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, @jeremiedimino)

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

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

Oops, we went looking but didn't find the changelog for this release 🙈

Oops, we went looking but didn't find the changelog for this release 🙈

General

• Better support for wide and combined glyph (@kandu)
• Added tips for simpe prompt without fancy features (Marshall Abrams, #279)
• Correct quoting for Windows command shell (Dmitry Bely, #272)

Additions

• 4.08 compatibility (#284)
• module UTop: add get_load_path and set_load_path to manage the include directories (#284)

Breaking

• module UTop: val load_path : string list ref is removed (#284)

• Make sure opening Ast_408 doesn't shadow Int or Misc (#71, @hhugo)
• Fix a couple of issues related to upgrading the AST from 4.07 to 4.08 (#71, @hhugo)

• 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)

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

• Get rid of the ocamlbuild plugin. Nobody is using it in opam and it is more work to maintain (#63, @diml)
• Set Location.input_name to the original filename when reading a binary AST (#66, @diml)
• Add support 4.08 (#70, @xclerc)

• Set Location.input_name to the original filename when reading a binary AST (#.., @diml)

• 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)

• 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)

• 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)
