1.0+beta20

1.0+beta20 (10/04/2018)

• Add a documentation stanza. This stanza allows one to attach .mld files to
  opam packages. (#570 @rgrinberg)

• Execute all actions (defined using (action ..)) in the context's
  environment. (#623 @rgrinberg)

• Add a (universe) special dependency to specify that an action depend on
  everything in the universe. Jbuilder cannot cache the result of an action that
  depend on the universe (#603, fixes #255 @diml)

• Add a (package <package>) dependency specification to indicate
  dependency on a whole package. Rules depending on whole pacakge will
  be executed in an environment similar to the one we get once the
  package is installed (#624, @rgrinberg and @diml)

• Don't pass -runtime-variant _pic on Windows (#635)

• Display documentation in alphabetical order. This is relevant to packages,
  libraries, and modules. (#647, fixes #606 @rgrinberg)

• Missing asm in ocaml -config on bytecode only architecture is no longer fatal.
  The same kind of fix is preemptively applied to C compilers being absent.
  (#646, fixes $637 @rgrinberg)

• Use the host's PATH variable when running actions during cross compilation
  (#649, fixes #625 @rgrinberg)

• Fix incorrect include (-I) flags being passed to odoc. These flags should be
  directories that include .odoc files, rather than the include flags of the
  libraries. (#652 fixes #651 @rgrinberg)

• Fix a regression introduced by beta19 where the generated merlin
  files didn't include the right -ppx flags in some cases (#658
  fixes #657 @diml)

• Fix error messaage when a public library is defined twice. Before
  jbuilder would raise an uncaught exception (Fixes #661, @diml)

• Fix several cases where external-lib-deps was returning too little
  dependencies (#667, fixes #644 @diml)

• Place module list on own line in generated entry point mld (#670 @antron)

• Cosmetic improvements to generated entry point mld (#653 @trefis)

1.0+beta19.1

1.0+beta19.1 (21/03/2018)

• Missing asm in ocaml -config on bytecode only architecture is no longer fatal
  (#637 fixed by #639 @rgrinberg)

• Fix regression introduced by beta19 where duplicate environment variables in
  Unix.environ would cause a fatal error. The first defined environment variable
  is now chosen. (#638 fixed by #640)

• Use ';' as the path separator for OCAMLPATH on Cygwin (#630 fixed by #636
  @diml).

• Use the contents of the OCAMLPATH environment variable when not relying on
  ocamlfind (#642 @diml)

1.0+beta19

1.0+beta19 (14/03/2018)

• Ignore errors during the generation of the .merlin (#569, fixes #568 and #51)

• Add a workaround for when a library normally installed by the
  compiler is not installed but still has a META file (#574, fixes
  #563)

• Do not depend on ocamlfind. Instead, hard-code the library path when
  installing from opam (#575)

• Change the default behavior regarding the check for overlaps between
  local and installed libraries. Now even if there is no link time
  conflict, we don't allow an external dependency to overlap with a
  local library, unless the user specifies allow_overlapping_dependencies
  in the jbuild file (#587, fixes #562)

• Expose a few more variables in jbuild files: ext_obj, ext_asm,
  ext_lib, ext_dll and ext_exe as well as ${ocaml-config:XXX}
  for most variables in the output of ocamlc -config (#590)

• Add support for inline and inline expectation tests. The system is
  generic and should support several inline test systems such as
  ppx_inline_test, ppx_expect or qtest (#547)

• Make sure modules in the current directory always have precedence
  over included directories (#597)

• Add support for building executables as object or shared object
  files (#23)

• Add a best mode which is native with fallback to byte-code when
  native compilation is not available (#23)

• Fix locations reported in error messages (#609)

• Report error when a public library has a private dependency. Previously, this
  would be silently ignored and install broken artifacts (#607).

• Fix display when output is not a tty (#518)

• Add a (universe) special dependency to specify that an action
  depend on everything in the universe. Jbuilder cannot cache the
  result of an action that depend on the universe (#603, fixes #255)

1.0+beta18.1

1.0+beta18.1 (14/03/2018)

• Reduce the number of simultaneously opened fds (#578)

• Always produce an implementation for the alias module, for
  non-jbuilder users (Fix #576)

• Reduce interleaving in the scheduler in an attempt to make Jbuilder
  keep file descriptors open for less long (#586)

• Accept and ignore upcoming new library fields: ppx.driver,
  inline_tests and inline_tests.backend

• Add a hack to be able to build ppxlib, until beta20 which will have
  generic support for ppx drivers

1.0+beta18

1.0+beta18 (25/02/2018)

• Fix generation of the implicit alias module with 4.02. With 4.02 it
  must have an implementation while with OCaml >= 4.03 it can be an
  interface only module (#549)

• Let the parser distinguish quoted strings from atoms. This makes
  possible to use "${v}" to concatenate the list of values provided by
  a split-variable. Concatenating split-variables with text is also
  now required to be quoted.

• Split calls to ocamldep. Before ocamldep would be called once per
  library/executables stanza. Now it is called once per file
  (#486)

• Make sure to not pass -I <stdlib-dir> to the compiler. It is
  useless and it causes problems in some cases (#488)

• Don't stop on the first error. Before, jbuilder would stop its
  execution after an error was encountered. Now it continues until
  all branches have been explored (#477)

• Add supprot for a user configuration file (#490)

• Add more display modes and change the default display of
  Jbuilder. The mode can be set from the command line or from the
  configuration file (#490)

• Allow to set the concurency level (-j N) from the configuration
  file (#491)

• Store artifacts for libraries and executables in separate
  directories. This ensure that Two libraries defined in the same
  directory can't see each other unless one of them depend on the
  other (#472)

• Better support for mli/rei only modules (#490)

• Fix support for byte-code only architectures (#510, fixes #330)

• Fix a regression in external-lib-deps introduced in 1.0+beta17
  (#512, fixes #485)

• @doc alias will now build only documentation for public libraries. A new
  @doc-private alias has been added to build documentation for private
  libraries.

• Refactor internal library management. It should now be possible to
  run jbuilder build @lint in Base for instance (#516)

• Fix invalid warning about non-existent direcotry (#536, fixes #534)

1.0+beta17

1.0+beta17 (01/02/2018)

• Make jbuilder aware that num is an external package in OCaml >= 4.06.0
  (#358)

• jbuilder exec will now rebuild the executable before running it if
  necessary. This can be turned off by passing --no-build (#345)

• Fix jbuilder utop to work in any working directory (#339)

• Fix generation of META synopsis that contains double quotes (#337)

• Add S . to .merlin by default (#284)

• Improve jbuilder exec to make it possible to execute non public executables.
  jbuilder exec path/bin will execute bin inside default (or specified)
  context relative to path. jbuilder exec /path will execute /path as
  absolute path but with the context's environment set appropriately. Lastly,
  jbuilder exec will change the root as to which paths are relative using the
  -root option. (#286)

• Fix jbuilder rules printing rules when some binaries are missing (#292)

• Build documentation for non public libraries (#306)

• Fix doc generation when several private libraries have the same name (#369)

• Fix copy# for C/C++ with Microsoft C compiler (#353)

• Add support for cross-compilation. Currently we are supporting the
  opam-cross-x repositories such as
  opam-cross-windows
  (#355)

• Simplify generated META files: do not generate the transitive
  closure of dependencies in META files (#405)

• Deprecated ${!...}: the split behavior is now a property of the
  variable. For instance ${CC}, ${^}, ${read-lines:...} all
  expand to lists unless used in the middle of a longer atom (#336)

• Add an (include ...) stanza allowing one to include another
  non-generated jbuild file in the current file (#402)

• Add a (diff <file1> <file2>) action allowing to diff files and
  promote generated files in case of mismatch (#402, #421)

• Add jbuilder promote and --auto-promote to promote files (#402,
  #421)

• Report better errors when using (glob_files ...) with a directory
  that doesn't exist (#413, Fix #412)

• Jbuilder now properly handles correction files produced by
  ppx_driver. This allows to use [@@deriving_inline] in .ml/.mli
  files. This require ppx_driver >= v0.10.2 to work properly (#415)

• Make jbuilder load rules lazily instead of generating them all
  eagerly. This speeds up the initial startup time of jbuilder on big
  workspaces (#370)

• Now longer generate a META.pkg.from-jbuilder file. Now the only
  way to customise the generated META file is through
  META.pkg.template. This feature was unused and was making the code
  complicated (#370)

• Remove read-only attribute on Windows before unlink (#247)

• Use /Fo instead of -o when invoking the Microsoft C compiler to eliminate
  deprecation warning when compiling C++ sources (#354)

• Add a mode field to rule stanzas:

  • (mode standard) is the default
  • (mode fallback) replaces (fallback)
  • (mode promote) means that targets are copied to the source tree
    after the rule has completed
  • (mode promote-until-clean) is the same as (mode promote) except
    that jbuilder clean deletes the files copied to the source tree.
    (#437)

• Add a flag --ignore-promoted-rules to make jbuilder ignore rules
  with (mode promote). -p implies --ignore-promoted-rules (#437)

• Display a warning for invalid lines in jbuild-ignore (#389)

• Always build boot.exe as a bytecode program. It makes the build of
  jbuilder faster and fix the build on some architectures (#463, fixes #446)

• Fix bad interaction between promotion and incremental builds on OSX
  (#460, fix #456)

1.0+beta16

1.0+beta16 (05/11/2017)

• Fix build on 32-bit OCaml on Windows/Cygwin (#313)

1.0+beta15

1.0+beta15 (04/11/2017)

• Change the semantic of aliases: there are no longer aliases that are
  recursive such as install or runtest. All aliases are
  non-recursive. However, when requesting an alias from the command
  line, this request the construction of the alias in the specified
  directory and all its children recursively. This allows users to get
  the same behavior as previous recursive aliases for their own
  aliases, such as example. Inside jbuild files, one can use (deps (... (alias_rec xxx) ...)) to get the same behavior as on the
  command line. (#268)

• Include sub libraries that have a . in the generated documentation index
  (#280).

• Fix "up" links to the top-level index in the odoc generated documentation
  (#282).

• Fix ARCH_SIXTYFOUR detection for OCaml 4.06.0 (#303)

1.0+beta14

1.0+beta14 (11/10/2017)

• Add (copy_files ) and (copy_files# ) stanzas. These
  stanzas setup rules for copying files from a sub-directory to the
  current directory. This provides a reasonable way to support
  multi-directory library/executables in jbuilder (#35, Francois Bobot)

• An empty jbuild-workspace file is now interpreted the same as one
  containing just (context default)

• Better support for on-demand utop toplevels on Windows and when the
  library has C stubs

• Print Entering directory '...' when the workspace root is not the
  current directory. This allows Emacs and Vim to know where relative
  filenames should be interpreted from. Fixes #138

• Fix a bug related to menhir stanzas: menhir stanzas with a
  merge_into field that were in jbuild files in sub-directories
  where incorectly interpreted (#264)

• Add support for locks in actions, for tests that can't be run
  concurrently (#263)

• Support ${..} syntax in the include stanza. (#231)

1.0+beta13

1.0+beta13 (05/09/2017)

• Generate toplevel html index for documentation (#224, Thomas Gazagnaire)

• Fix recompilation of native artifacts. Regression introduced in the last
  version (1.0+beta12) when digests replaces timestamps for checking staleness
  (#238, David Allsopp)
