package jbuilder

1.0+beta20.1 (02/12/2019)

• Fix compat with OCaml >= 4.08

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 (21/03/2018)

• 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 (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)

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 (#588)
• Add a hack to be able to build ppxlib, until beta20 which will have generic support for ppx drivers

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 (#489)
• 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 (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 (05/11/2017)

• Fix build on 32-bit OCaml (#313)

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 (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 (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)

1.0+beta12 (18/08/2017)

• Fix the quoting of FLG lines in generated .merlin files (#200, Marcello Seri)
• Use the full path of archive files when linking. Before jbuilder would do: -I <path> file.cmxa, now it does -I <path> <path>/file.cmxa. Fixes #118 and #177
• Use an absolute path for ppx drivers in .merlin files. Merlin <3.0.0 used to run ppx commands from the directory where the .merlin was present but this is no longer the case
• Allow to use jbuilder install in contexts other than opam; if ocamlfind is present in the PATH and the user didn't pass --prefix or --libdir explicitly, use the output of ocamlfind printconf destdir as destination directory for library files (#179, Francois Bobot)
• Allow (:include ...) forms in all *flags fields (#153, David Allsopp)
• Add a utop subsommand. Running jbuilder utop in a directory builds and executes a custom utop toplevel with all libraries defined in the current directory (#183, Rudi Grinberg)
• Do not accept per_file anymore in preprocess field. per_file was renamed per_module and it is planned to reuse per_file for another purpose
• Warn when a file is both present in the source tree and generated by a rule. Before, jbuilder would silently ignore the rule. One now has to add a field (fallback) to custom rules to keep the current behavior (#218)
• Get rid of the deprecated-ppx-method findlib package for ppx rewriters (#222, fixes #163)
• Use digests (MD5) of files contents to detect changes rather than just looking at the timestamps. We still use timestamps to avoid recomputing digests. The performance difference is negligible and we avoid more useless recompilations, especially when switching branches for instance (#209, fixes #158)

1.0+beta11 (21/07/2017)

• Fix the error message when there are more than one <package>.opam file for a given pacakge
• Report an error when in a wrapped library, a module that is not the toplevel module depends on the toplevel module. This doesn't make as such a module would in theory be inaccessible from the outside
• Add ${SCOPE_ROOT} pointing to the root of the current scope, to fix some misuses of ${ROOT}
• Fix useless hint when all missing dependencies are optional (#137)
• Fix a bug preventing one from generating META.pkg.template with a custom rule (#190)
• Fix compilation of reason projects: .rei files where ignored and caused the build to fail (#184)

1.0+beta10 (08/06/2017)

• Add a clean subcommand (Richard Davison, #89)
• Add support for generating API documentation with odoc (#74)
• Don't use unix in the bootstrap script, to avoid surprises with Cygwin
• Improve the behavior of jbuilder exec on Windows
• Add a --no-buffer option to see the output of commands in real-time. Should only be used with -j1
• Deprecate per_file in preprocessing specifications and rename it per_module
• Deprecate copy-and-add-line-directive and rename it copy#
• Remove the ability to load arbitrary libraries in jbuild file in OCaml syntax. Only unix is supported since a few released packages are using it. The OCaml syntax might eventually be replaced by a simpler mechanism that plays better with incremental builds
• Properly define and implement scopes
• Inside user actions, ${^} now includes files matches by (glob_files ...) or (file_recursively_in ...)
• When the dependencies and targets of a rule can be inferred automatically, you no longer need to write them: (rule (copy a b))
• Inside (run ...), ${xxx} forms that expands to lists can now be split across multiple arguments by adding a !: ${!xxx}. For instance: (run foo ${!^})

• Add support for using the contents of a file inside an action:

  • ${read:<file>}
  • ${read-lines:<file>}
  • ${read-strings:<file>} (same as read-lines but lines are escaped using OCaml convention)
• When exiting prematurely because of a failure, if there are other background processes running and they fail, print these failures
• With msvc, -lfoo is transparently replaced by foo.lib (David Allsopp, #127)
• Automatically add the .exe when installing executables on Windows (#123)
• (run <prog> ...) now resolves <prog> locally if possible. i.e. (run ${bin:prog} ...) and (run prog ...) behave the same. This seems like the right default
• Fix a bug where jbuild rules would crash instead of reporting a proper build error
• Fix a race condition in future.ml causing jbuilder to crash on Windows in some cases (#101)
• Fix a bug causing ppx rewriter to not work properly when using multiple build contexts (#100)
• Fix .merlin generation: projects in the same workspace are added to merlin's source path, so "locate" works on them.

1.0+beta9 (19/05/2017)

• Add support for building Reason projects (Rudi Grinberg, #58)
• Add support for building javascript with js-of-ocaml (Hugo Heuzard, #60)
• Better support for topkg release workflow. See topkg-jbuilder for more details
• Port the manual to rst and setup a jbuilder project on readthedocs.org (Rudi Grinberg, #78)
• Hint for mistyped targets. Only suggest correction on the basename for now, otherwise it's slow when the workspace is big
• Add a (package ...) field for aliases, so that one can restrict tests to a specific package (Rudi Grinberg, #64)

• Fix a couple of bugs on Windows:

  • fix parsing of end of lines in some cases
  • do not take the case into account when comparing environment variable names
• Add AppVeyor CI
• Better error message in case a chain of dependencies crosses the installed world
• Better error messages for invalid dependency list in jbuild files

• Severel improvements/fixes regarding the handling of findlib packages:

  • Better error messages when a findlib package is unavailable
  • Don't crash when an installed findlib package has missing dependencies
  • Handle the findlib alternative directory layout which is still used by a few packages
• Add jbuilder installed-libraries --not-available explaining why some libraries are not available
• jbuilder now records dependencies on files of external libraries. This mean that when you upgrade a library, jbuilder will know what need to be rebuilt.
• Add a jbuilder rules subcommand to dump internal compilation rules, mostly for debugging purposes

• Ignore all directories starting with a . or _. This seems to be a common pattern:

  • .git, .hg, _darcs
  • _build
  • _opam (opam 2 local switches)
• Fix the hint for jbuilder external-lib-deps (#72)
• Do not require ocamllex and ocamlyacc to be at the same location as ocamlc (#75)

1.0+beta8 (17/04/2017)

• Added ${lib-available:<library-name>} which expands to true or false with the same semantic as literals in (select ...) stanzas
• Remove hard-coded knowledge of a few specific ppx rewriters to ease maintenance moving forward
• Pass the library name to ppx rewriters via the library-name cookie
• Fix: make sure the action working directory exist before running it

1.0+beta7 (12/04/2017)

• Make the output quieter by default and add a --verbose argument (Stephen Dolan, #40)
• Various documentation fixes (Adrien Guatto, #41)
• Make @install the default target when no targets are specified (Stephen Dolan, #47)
• Add predefined support for menhir, similar to ocamlyacc support (Rudi Grinberg, #42)
• Add internal support for sandboxing actions and sandbox the build of the alias module with 4.02 to workaround the compiler trying to read the cmi of the aliased modules
• Allow to disable dynlink support for libraries via (no_dynlink) (#55)
• Add a -p/--for-release-of-packages command line argument to simplify the jbuilder invocation in opam files and make it more future proof (#52)
• Fix the lookup of the executable in jbuilder exec foo. Before, even if foo was to be installed, the freshly built version wasn't selected
• Don't generate a exists_if ... lines in META files. These are useless sine the META files are auto-generated

1.0+beta6 (29/03/2017)

• Add an (executable ...) stanza for single executables (#33)
• Add a (package ...) and (public_name <name>)/(public_names (<names)) to executable/executables stanzas to make it easier to install executables (#33)
• Fix a bug when using specific rewriters that jbuilder knows about without ppx_driver.runner (#37). These problem should go away soon when we start using --cookie
• Fix the interpretation of META files when there is more than one applicable assignment. Before this fix, the one with the lowest number of formal predicates was selected instead of the one with the biggest number of formal predicates

1.0+beta5 (22/03/2017)

• When ocamlfind is present in the PATH, do not attempt to call opam config var lib
• Make sure the build of jbuilder itself never calls ocamlfind or opam
• Better error message when a jbuild file in OCaml syntax forgets to call Jbuild_plugin.V*.send
• Added examples of use
• Don't drop inline tests/benchmarks by default

1.0+beta4 (20/03/2017)

• Improve error messages about invalid/missing pkg.opam files
• Ignore all errors while running ocamlfind printconf path

1.0+beta3 (15/03/2017)

• Print optional dependencies as optional in the output of jbuilder external-lib-deps --missing

• Added a few forms to the DSL:

  • with-{stderr,outputs}-to
  • ignore-{stdout,stderr,outputs}
• Added ${null} which expands to /dev/null on Unix and NUL on Windows
• Improve the doc generated by odoc for wrapped libraries
• Improve the error reported when an installed package depends on a library that is not installed
• Documented (files_recursively_in ...)
• Added black box tests
• Fix a bug where jbuilder would crash when there was no <package>.opam file
• Fixed a bug where .merlin files where not generated at the root of the workspace (#20)
• Fix a bug where a (glob_files ...) would cause other dependencies to be ignored
• Fix the generated ppx(...) line in META files
• Fix (optional) when a ppx runtime dependency is not available (#24)
• Do not crash when an installed package that we don't need has missing dependencies (#25)

1.0+beta2 (10/03/2017)

• Simplified the rules for finding the root of the workspace as the old ones were often picking up the home directory. New rules are:

  • look for a jbuild-workspace file in parent directories
  • look for a jbuild-workspace* file in parent directories
  • use the current directory
• Fixed the expansion of ${ROOT} in actions
• Install quick-start.org in the documentation directory
• Add a few more things in the log file to help debugging

1.0+beta1 (07/03/2017)

• Added a manual
• Support incremental compilation
• Switched the CLI to cmdliner and added a build command (#5, Rudi Grinberg)

• Added a few commands:

  • runtest
  • install
  • uninstall
  • installed-libraries
  • exec: execute a command in an environment similar to what you would get after jbuilder install
• Removed the build-package command in favor of a --only-packages option that is common to all commands
• Automatically generate .merlin files (#2, Richard Davison)
• Improve the output of jbuilder, in particular don't mangle the output of commands when using -j N with N > 1
• Generate a log in _build/log
• Versioned the jbuild format and added a first stable version. You should now put (jbuilder_version 1) in a jbuild file at the root of your project to ensure forward compatibility
• Switch from ppx_driver to ocaml-migrate-parsetree.driver. In order to use ppx rewriters with Jbuilder, they need to use ocaml-migrate-parsetree.driver
• Added support for aliases (#7, Rudi Grinberg)
• Added support for compiling against multiple opam switch simultaneously by writing a jbuild-worspace file
• Added support for OCaml 4.02.3
• Added support for architectures that don't have natdynlink
• Search the root according to the rules described in the manual instead of always using the current directory

• extended the action language to support common actions without using a shell:

  • (with-stdout-to <file> <DSL>)
  • (copy <src> <dst>)
  • ...
• Removed all implicit uses of bash or the system shell. Now one has to write explicitely (bash "...") or (system "...")
• Generate meaningful versions in META files
• Strengthen the scope of a package. Jbuilder knows about package foo only in the sub-tree starting from where foo.opam lives

0.1.alpha1 (04/12/2016)

First release
