dune-package
files. The error is now raised
only if the invalid package is treated as a library and used to build
something. (#2972, @rgrinberg)On behalf of the dune team, I'm delighted to announce the release of dune 2.0. This release is the culmination of 4 months of hard work by the dune team and contains new features, bug fixes, and performance improvements . Here's a selection of new features that I personally find interesting:
(deprecated_library_name ..)
stanza to properly deprecate old library names(foreign_library ..)
stanza to define C/C++ libraries.Refer to the change log for an exhaustive list.
We strive for a good out of the box experience that requires no configuration, so we've also tweaked a few defaults. In particular, $ dune build
will now build @all
instead of @install
, and ocamlformat rules are setup by default.
Lastly, dune 2.0 sheds all the legacy related to jbuilder and will no longer build jbuilder projects. This change is necessary to ease maintenance and make it easier to add new features down the line. There are a few other minor breaking changes. Refer to the change log for the full list. We apologize in advance for any convenience this might cause.
Happy Hacking!
Remove existing destination files in install
before installing the new
ones. (#2885, fixes #2883, @bschommer)
The action
field in the alias
stanza is not available starting lang dune 2.0
. The alias
field in the rule
stanza is a replacement. (#2846, fixes
2681, @rgrinberg)
Introduce alias
and package
fields to the rule
stanza. This is the
preferred way of attaching rules to aliases. (#2744, @rgrinberg)
Add field (optional)
for executable stanzas (#2463, fixes #2433, @bobot)
Infer targets for rule stanzas expressed in long form (#2494, fixes #2469, @NathanReb)
Indicate the progress of the initial file tree loading (#2459, fixes #2374, @bobot)
Build .cm[ox]
files for executables more eagerly. This speeds up builds at
the cost of building unnecessary artifacts in some cases. Some of these extra
artifacts can fail to built, so this is a breaking change. (#2268, @rgrinberg)
Do not put the <package>.install
files in the source tree unless -p
or
--promote-install-files
is passed on the command line (#2329, @jeremiedimino)
Compilation units of user defined executables are now mangled by default. This is done to prevent the accidental collision with library dependencies of the executable. (#2364, fixes #2292, @rgrinberg)
Enable (explicit_js_mode)
by default. (#1941, @nojb)
Add an option to clear the console in-between builds with
--terminal-persistence=clear-on-rebuild
Stop symlinking object files to main directory for stanzas defined jbuild
files (#2440, @rgrinberg)
Library names are now validated in a strict fashion. Previously, invalid names would be allowed for unwrapped libraries (#2442, @rgrinberg)
mli only modules must now be explicitly declared. This was previously a warning and is now an error. (#2442, @rgrinberg)
Modules filtered out from the module list via the Ordered Set Language must now be actual modules. (#2442, @rgrinberg)
Actions which introduce targets where new targets are forbidden (e.g. preprocessing) are now an error instead of a warning. (#2442, @rgrinberg)
No longer install a jbuilder
binary. (#2441, @jeremiedimino)
Stub names are no longer allowed relative paths. This was previously a warning and is now an error (#2443, @rgrinberg).
Define (paths ...) fields in (context ...) definitions in order to set or extend any PATH-like variable in the context environment. (#2426, @nojb)
The diff
action will always normalize newlines before diffing. Perviousy, it
would not do this normalization for rules defined in jbuild files. (#2457,
@rgrinberg)
Modules may no longer belong to more than one stanza. This was previously
allowed only in stanzas defined in jbuild
files. (#2458, @rgrinberg)
Remove support for jbuild-ignore
files. They have been replaced by the the
dirs
stanza in dune
files. (#2456, @rgrinberg)
Add a new config option sandboxing_preference
, the cli argument --sandbox
,
and the dep spec sandbox
in dune language. These let the user control the level of
sandboxing done by dune per rule and globally. The rule specification takes precedence.
The global configuration merely specifies the default.
(#2213, @aalekseyev, @jeremiedimino)
Remove support for old style subsystems. Dune will now emit a warning to reinstall the library with the old style subsystem. (#2480, @rgrinberg)
Add action (with-stdin-from
Change the automatically generated odoc index to only list public modules. This only affects unwrapped libraries (#2479, @rgrinberg)
Set up formatting rules by default. They can be configured through a new
(formatting)
stanza in dune-project
(#2347, fixes #2315, @emillon)
Change default target from @install
to @all
. (#2449, fixes #1220,
@rgrinberg)
Include building stubs in @check
rules. (@rgrinberg, #2530)
Get rid of ad-hoc rules for guessing the version. Dune now only
relies on the version written in the dune-project
file and no
longer read VERSION
or similar files (#2541, @jeremiedimino)
In (diff? x y)
action, require x
to exist and register a
dependency on that file. (#2486, @aalekseyev)
On Windows, an .exe suffix is no longer added implicitly to binary names that already end in .exe. Second, when resolving binary names, .opt variants are no longer chosen automatically. (#2543, @nojb)
Make (diff? x y)
move the correction file (y
) away from the build
directory to promotion staging area. This makes corrections work with
sandboxing and in general reduces build directory pollution. (#2486,
@aalekseyev, fixes #2482)
c_flags
, c_names
and cxx_names
are now supported in executable
and executables
stanzas. (#2562, @nojb)
Note: this feature has been subsequently extended into a separate
foreign_stubs
field. (#2659, RFC #2650, @snowleopard)
Remove git integration from $ dune upgrade
(#2565, @rgrinberg)
Add a --disable-promotion
to disable all modification to the source
directory. There's also a corresponding DUNE_DISABLE_PROMOTION
environment
variable. (#2588, fix #2568, @rgrinberg)
Add a forbidden_libraries
field to prevent some library from being
linked in an executable. This help detecting who accidently pulls in
unix
for instance (#2570, @jeremiedimino)
Fix incorrect error message when a variable is expanded in static context:
%{lib:lib:..}
when the library does not exist. (#2597, fix #1541,
@rgrinberg)
Add --sections
option to $ dune install
to install subsections of .install
files. This is useful for installing only the binaries in a workspace for
example. (#2609, fixes #2554, @rgrinberg)
Drop support for jbuild
and jbuild-ignore
files (#2607, @jeremiedimino)
Add a dune-action-plugin
library for describing dependencies direcly in
the executable source. Programs that use this feature can be run by a new
action (dynamic-run
Stop installing the ocaml-syntax-shims
binary. In order to use
future_syntax
, one now need to depend on the ocaml-syntax-shims
package (#2654, @jeremiedimino)
Add support for dependencies that are re-exported. Such dependencies
are marked withre_export
and will automatically be provided to
users of a library (#2605, @rgrinberg)
Add a deprecated_library_name
stanza to redirect old names after a
library has been renamed (#2528, @jeremiedimino)
Error out when a preprocessor_deps
field is present but not
preprocess
field is. It is a warning with Dune 1.x projects
(#2660, @Julow)
Dune will use -output-complete-exe
instead of -custom
when compiling
self-contained bytecode executables whenever this options is available
(OCaml version >= 4.10) (#2692, @nojb)
Add action (with-accepted-exit-codes <pred> <action>)
to specify the set of
successful exit codes of <action>
. <pred>
is specified using the predicate
language. (#2699, @nojb)
Do not setup rules for disabled libraries (#2491, fixes #2272, @bobot)
Configurator: filter out empty flags from pkg-config
(#2716, @AltGr)
no_keep_locs
is a no-op for projects that use lang dune
older than 2.0. In
projects where the language is at least 2.0
, the field is now forbidden.
(#2752, fixes #2747, @rgrinberg)
Extend support for foreign sources and archives via the (foreign_library ...)
stanza as well as the (foreign_stubs ...)
and (foreign_archives ...)
fields.
(#2659, RFC #2650, @snowleopard)
Add (deprecated_package_names) field to (package) declaration in dune-project. The names declared here can be used in the (old_public_name) field of (deprecated_library_name) stanza. These names are interpreted as library names (not prefixed by a package name) and appropiate redirections are setup in their META files. This feaure is meant to migrate old libraries which do not follow Dune's convention of prefixing libraries with the package name. (#2696, @nojb)
The fields license
, authors
, maintainers
, source
, bug_reports
,
homepage
, and documentation
of dune-project
can now be overriden on a
per-package basis. (#2774, @nojb)
Change the default modes
field of executables to (mode exe)
. If
one wants to build a bytecode program, it now needs to be explicitly
requested via (modes byte exe)
. (#2851, @jeremiedimino)
Allow ccomp_type
as a variable for evaluating enabled_if
. (#2855, @dra27,
@rgrinberg)
Stricter validation of file names in select
. The file names of conditional
sources must match the prefix and the extension of the resultant filename.
(#2867, @rgrinberg)
Add flag disable_dynamically_linked_foreign_archives
to the workspace file.
If the flag is set to true
then: (i) when installing libraries, we do not
install dynamic foreign archives dll*.so
; (ii) when building executables in
the byte
mode, we statically link in foreign archives into the runtime
system; (iii) we do not generate any dll*.so
rules. (#2864, @snowleopard)
Reimplement the bootstrap procedure. The new procedure is faster and should no longer stack overflow (#2854, @dra27, @jeremiedimino)
Allow .opam.template
files to be generated using rules (#2866, @rgrinberg)
Allow to mark directories as data_only_dirs
without including them as dirs
(#2619, fix #2584, @rgrinberg)
Fix reading .install
files generated with an external --build-dir
. (#2638,
fix #2629, @rgrinberg)
Remove the optimisation of passing -nodynlink
for executables when
not necessary. It seems to be breaking things (see #2527, @diml)
Fix invalid library names in dune-package
files. Only public names should
exist in such files. (#2558, fix #2425, @rgrinberg)
Fix config file dependencies of ocamlformat (#2471, fixes #2464, @nojb)
Cleanup stale directories when using (source_tree ...)
in the
presence of directories with only sub-directories and no files
(#2514, fixes #2499, @diml)
On behalf of the dune team, I'm pleased to announce the release of dune 1.11.0. This release contains quite a few new interesting features such as custom dialects: anyone can define their own OCaml based syntax. Is anyone up to revive the revised syntax? :slight_smile: I'd also like to highlight the the re-launch of variants feature in a sounder form, a new build-info
library that queries build information, and that dune init
can initialize an entire project. But of course, by far the most important thing is that the compiler's colours are now back :champagne:
Don't select all local implementations in dune utop
. Instead, let the
default implementation selection do its job. (#2327, fixes #2323, @TheLortex,
review by @rgrinberg)
Check that selected implementations (either by variants or default implementations) are indeed implementations. (#2328, @TheLortex, review by @rgrinberg)
Don't reserve the Ppx
toplevel module name for ppx rewriters (#2242, @jeremiedimino)
Redesign of the library variant feature according to the #2134 proposal. The
set of variants is now computed when the virtual library is installed.
Introducing a new external_variant
stanza. (#2169, fixes #2134, @TheLortex,
review by @jeremiedimino)
Add proper line directives when copying .cc
and .cxx
sources (#2275,
@rgrinberg)
Fix error message for missing C++ sources. The .cc
extension was always
ignored before. (#2275, @rgrinberg)
Add $ dune init project
subcommand to create project boilerplate according
to a common template. (#2185, fixes #159, @shonfeder)
Allow to run inline tests in javascript with nodejs (#2266, @hhugo)
Build ppx.exe
as compiling host binary. (#2286, fixes #2252, @toots, review
by @rgrinberg and @jeremiedimino)
Add a cinaps
extension and stanza for better integration with the
cinaps tool tool (#2269,
@jeremiedimino)
Allow to embed build info in executables such as version and list and version of statically linked libraries (#2224, @jeremiedimino)
Set version in META
and dune-package
files to the one read from
the vcs when no other version is available (#2224, @jeremiedimino)
Add a variable %{target}
to be used in situations where the context
requires at most one word, so %{targets}
can be confusing; stdout
redirections and "-o" arguments of various tools are the main use
case; also, introduce a separate field target
that must be used
instead of targets
in those situations. (#2341, @aalekseyev)
Fix dependency graph of wrapped_compat modules. Previously, the dependency on the user written entry module was omitted. (#2305, @rgrinberg)
Allow to promote executables built with an executable
stanza
(#2379, @jeremiedimino)
When instantiating an implementation with a variant, make sure it matches virtual library's list of known implementations. (#2361, fixes #2322, @TheLortex, review by @rgrinberg)
Add a variable %{ignoring_promoted_rules}
that is true
when
--ingore-promoted-rules
is passed on the command line and false
otherwise (#2382, @jeremiedimino)
Fix a bug in future_syntax
where the characters @
and &
were
not distinguished in the names of binding operators (let@
was the
same as let&
) (#2376, @aalekseyev, @jeremiedimino)
Workspaces with non unique project names are now supported. (#2377, fix #2325, @rgrinberg)
Improve opam generation to include the dune
dependencies with the minimum
constraint set based on the dune language version specified in the
dune-project
file. (2383, @avsm)
The order of fields in the generated opam file now follows order preferred in opam-lib. (@avsm, #2380)
Fix coloring of error messages from the compiler (@jeremiedimino, #2384)
Add warning 66
to default set of warnings starting for dune projects with
language verison >= 1.11
(@rgrinberg, @jeremiedimino, fixes #2299)
Add (dialect ...) stanza (@nojb, #2404)
Add a --context
argument to dune install/uninstall
(@jeremiedimino, #2412)
Do not warn about merlin files pre 1.9. This warning can only be disabled in 1.9 (#2421, fixes #2399, @emillon)
Add a new inline_tests
field in the env stanza to control inline_tests
framework with a variable (#2313, @mlasson, original idea by @jeremiedimino, review
by @rgrinberg).
New binary kind js
for executables in order to explicitly enable Javascript
targets, and a switch (explicit_js_mode)
to require this mode in order to
declare JS targets corresponding to executables. (#1941, @nojb)
On behalf of the dune team, I'm pleased to announce the 1.10.0 release of dune. This release is packed with bug fixes, but it also introduces a few interesting features. I'll highlight one important feature that we've introduced and plan to improve in future versions:
Dune allows you to specify package metadata in the dune project file and generate an appropriate opam file. This is advantageous to writing opam files manually as dune will correctly fill in some boilerplate such as the build command:
Here's a snippet from dune's own project file as a demonstration:
(generate_opam_files true) ;; necessary to enbale the generation
(license MIT)
(maintainers "Jane Street Group, LLC <opensource@janestreet.com>")
(authors "Jane Street Group, LLC <opensource@janestreet.com>")
(source (github ocaml/dune))
(documentation "https://dune.readthedocs.io/")
(package
(name dune)
(depends
(ocaml (>= 4.02))
base-unix
base-threads)
(conflicts
(jbuilder (<> "transition"))
(odoc (< 1.3.0))
(dune-release (< 1.3.0)))
(synopsis "Fast, portable and opinionated build system")
(description "<redacted>"))
Generating the opam file is done via $ dune build @check
(the @install
, and @all
aliases will also work).
Later, we plan to have dune do some sanity checks on the depends
field. In the more distant future, we might even skip the generation step altogether by having opam invoke dune to get the generated opam file directly.
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)
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)
.install
files not being generated (#2124, fixes #2123, @rgrinberg)On behalf of the dune team, I'm pleased to announce the release of Dune 1.9.0. This release introduces a few exciting new features:
dune init
command to help users quickly generate boilerplate and get start with dune projects (contributed by @shonfeder)I would like to thank Lucas Pluvinage and @ejgallego for contributing the first two features respectively. They've also collaborated on a blog post to describe these features in detail.
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)
index.mld
. Use correct headings for the listing. (#1925,
@rgrinberg, @aantron)dune-package
when version is empty string (#1919, fix #1918,
@rgrinberg)On behalf of the dune team, I'm pleased to announce release 1.8. The highlight of this release is a standalone preprocessor that allows OCaml programs to use the new let bindings introduced in 1.8 and still be compatible with OCaml versions all the way back to 4.02.
This release includes some important contributions from a new contributor: @aalekseyev. So I would like to use this opportunity to welcome him to the team. Thanks Arseniy!
Clean up watch mode polling loop: improves signal handling and error handling during polling (#1912, fix #1907, fix #1671, @aalekseyev)

Add DUNE_WORKSPACE
variable. This variable is equivalent to setting
--workspace
in the command line. (#1711, fix #1503, @rgrinberg)

On behalf of the dune team, I'm pleased to announce the release of dune 1.7.0. This release is the biggest release since 1.0 and I'm excited to present it to you. The change log is quite long so I'll summarize the most noteworthy changes:
The jbuilder binary and jbuild files are officially deprecated. But not to worry, we've created a $ dune upgrade
command to do the hard work for you.
The virtual libraries feature has made it to 1.7.0. I've blogged about it before
There's now a mode to disable transitive dependencies. This mode still has some caveats because it lacks proper compiler support. But we welcome user reports regarding its usability.
Dune now has a --trace-file
to profile slow builds using shiny flame graphs in Chrome.
Second step of the deprecation of jbuilder: the jbuilder
binary
now emits a warning on every startup and both jbuilder
and dune
emit warnings when encountering jbuild
files (#1752, @jeremiedimino)
Change the layout of build artifacts inside _build. The new layout enables
optimizations that depend on the presence of .cmx
files of private modules
(#1676, @bobot)
Fix merlin handling of private module visibility (#1653 @bobot)
unstable-fmt: use boxes to wrap some lists (#1608, fix #1153, @emillon, thanks to @rgrinberg)
skip directories when looking up programs in the PATH (#1628, fixes #1616, @jeremiedimino)
Use lsof
on macOS to implement --stats
(#1636, fixes #1634, @xclerc)
Generate dune-package
files for every package. These files are installed and
read instead of META
files whenever they are available (#1329, @rgrinberg)
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)
When executing actions, open files lazily and close them as soon as possible in order to reduce the maximum number of file descriptors opened by Dune (#1635, #1643, fixes #1633, @jonludlam, @rgrinberg, @jeremiedimino)
Reimplement the core of Dune using a new generic memoization system (#1489, @rudihorn, @jeremiedimino)
Replace the broken cycle detection algorithm by a state of the art one from this paper (#1489, @rudihorn)
Get the correct environment node for multi project workspaces (#1648, @rgrinberg)
Add dune compute
to call internal memoized functions (#1528,
@rudihorn, @jeremiedimino)
Add --trace-file
option to trace dune internals (#1639, fix #1180, @emillon)
Add --no-print-directory
(borrowed from GNU make) to suppress
Entering directory
messages. (#1668, @dra27)
Remove --stats
and track fd usage in --trace-file
(#1667, @emillon)
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)
Look for jsoo runtime in the same dir as the js_of_ocaml
binary
when the ocamlfind package is not available (#1467, @nojb)
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 (implicit_transitive_deps <bool>)
mode to dune projects. When this mode
is turned off, transitive dependencies are not accessible. Only listed
dependencies are directly accessible. (#1734, #430, @rgrinberg, @hnrgrgr)
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)
Deprecate the undocumented (no_keep_locs)
field. It was only
necessary until virtual libraries were supported (#1822, fix #1816,
@jeremiedimino)
Rename unstable-fmt
to format-dune-file
and remove its --inplace
option.
(#1821, @emillon).
Autoformatting: (using fmt 1.1)
will also format dune files (#1821, @emillon).
Autoformatting: record dependencies on .ocamlformat-ignore
files (#1824,
fixes #1793, @emillon)
The dune team is pleased to announce the bug fix release of Dune 1.6.3. Normally, we don't bother announcing all bug fix releases, but this one contains quite a few fixes. I'd like to take this opportunity to encourage everyone to upgrade. Cheers.

Nevertheless, I expect that this will be a quality of life improvement to power users who have experienced dune's sharper corners.
Happy hacking!
Expand variables in install
stanzas (#1354, @mseri)

On behalf of the dune team, I'm pleased to announce the 1.5.0 release of dune. This release does not contain any major features, but it does contain a few notable bug fixes and a couple of useful little additions. First of all, $ dune exec
now supports C-c
again - I know this affected many of you. This releases introduces a couple of new aliases that will hopefully find their way into your workflows.
The first alias is @all
and has been much requested by our users. $ dune build @dir/all
will build all user defined targets in a the directory dir
. This would include binaries, libraries, and user defined targets in dir
. This alias should have been the defaulted instead of @install
when running $ dune build
, but we'll have to wait until dune 2.0 to make this compatibility breaking change. In the mean time, I highly recommend everyone to use $ dune build @all
instead of $ dune build
meanwhile. You may also set the default alias per project as well:
(alias
(name default)
(deps (alias_rec all)))
The second new alias is @check
. It is inspired by cargo's check
subcommand and roughly corresponds to type checking the project and building all artifacts necessary for editor integration - cmt, cmti's, .merlin, etc. This is the fastest target to verify that a project is in a valid state. Note that this alias will not relink binaries so it might not catch errors such as missing stubs. I find this alias handy when doing large, type driven refactoring of a codebase.
The rest of the change log is replicated below. Happy hacking!
Filter out empty paths from OCAMLPATH
and PATH
(#1436, @rgrinberg)
Do not add the lib.cma.js
target in lib's directory. Put this target in a
sub directory instead. (#1435, fix #1302, @rgrinberg)
Install generated OCaml files with a .ml
rather than a .ml-gen
extension

Fix interpretation of paths in env
stanzas (#1509, fixes #1508, @jeremiedimino)
Add context_name
expansion variable (#1507, @rgrinberg)
Use shorter paths for generated on-demand ppx drivers. This is to help Windows builds where paths are limited in length (#1511, fixes #1497, @jeremiedimino)
Fix interpretation of environment variables under setenv
. Also forbid
dynamic environment names or values (#1503, @rgrinberg).
The dune team is pleased to announce the 1.4.0 release of Dune. The highlight of this release is the improved support for menhir, in particular the long awaited --infer
flag. This seemingly small feature took quite a bit of coordination between the maintainers of dune and menhir. So I'd like to thank @fpottier for helping us out with this by adding better support for dune in menhir itself, and implementing the majority of the support in dune as well.
The rest of the release is mostly bug fixes, but one notable feature is that dune is now C-c
friendly. Dune will now resume exactly where it's stopped after interruption instead of restarting the entire build.
EDIT: I actually forgot to mention that this release also includes integration with OCamlFormat due to @emillon. Initially, I had thought that this feature was released in 1.3.0. Sorry about that!
