This pull request adds dune-action-plugin library.

What it does

This change makes possible to describe dependencies directly in source code of executable and to express dependencies that are selected based on content of previous dependencies.

To use this feature in an executable, user needs to link it against dune-action-plugin library and use provided API to describe dependencies. Then the executable can be used as a part of build process by declaring it as a part of the rule action.

API

User-facing API can be found in src/dune_action_plugin/dune_action_plugin.mli.

Examples

Examples of use can be found in src/dune_action_plugin/examples directory.

Testing

Tests can be found in test/blackbox-tests/test-cases-with-libs/dune-action-plugin and in test/expect-tests/dune_action_plugin.

What changes inside dune

  • New available construction in action definition: dynamic-run.
    This is similar to current run but tells dune, that the executable is using dune-action-plugin.
  • New variant in Action.t type: Dynamic_run and some changes in Action_exec module to handle the Dynamic_run and communication with client executable.
  • Trace_db in build_system.ml that is used to track when rule need to be rerun now stores more data to handle Dynamic_run.

Due to problem with package dependencies, this library will remain as a private dune package. After the dune.configurator split is done, this can be exposed as a public package.

We should pull in staronj#3 soon, by the way. That adds support for globs.

…lugin, dune-private-libs and dune-glob (2.0.0+draft1)

CHANGES:

- Introduce `alias` and `package` fields to the `rule` stanza. This is the
  preferred way of attaching rules to aliases. (ocaml/dune#2744, @rgrinberg)

- Add field `(optional)` for executable stanzas (ocaml/dune#2463, fixes ocaml/dune#2433, @bobot)

- Infer targets for rule stanzas expressed in long form (ocaml/dune#2494, fixes ocaml/dune#2469,
  @NathanReb)

- Indicate the progress of the initial file tree loading (ocaml/dune#2459, fixes ocaml/dune#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. (ocaml/dune#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 (ocaml/dune#2329, @diml)

- Change `implicit_transive_deps` to be false. Implicit transitive deps now must
  be manually enabled (ocaml/dune#2306, @rgrinberg)

- 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. (ocaml/dune#2364, fixes ocaml/dune#2292, @rgrinberg)

- Enable `(explicit_js_mode)` by default. (ocaml/dune#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 (ocaml/dune#2440, @rgrinberg)

- Library names are now validated in a strict fashion. Previously, invalid names
  would be allowed for unwrapped libraries (ocaml/dune#2442, @rgrinberg)

- mli only modules must now be explicitly declared. This was previously a
  warning and is now an error. (ocaml/dune#2442, @rgrinberg)

- Modules filtered out from the module list via the Ordered Set Language must
  now be actual modules. (ocaml/dune#2442, @rgrinberg)

- Actions which introduce targets where new targets are forbidden (e.g.
  preprocessing) are now an error instead of a warning. (ocaml/dune#2442, @rgrinberg)

- No longer install a `jbuilder` binary. (ocaml/dune#2441, @diml)

- Stub names are no longer allowed relative paths. This was previously a warning
  and is now an error (ocaml/dune#2443, @rgrinberg).

- Define (paths ...) fields in (context ...) definitions in order to set or
  extend any PATH-like variable in the context environment. (ocaml/dune#2426, @nojb)

- The `diff` action will always normalize newlines before diffing. Perviousy, it
  would not do this normalization for rules defined in jbuild files. (ocaml/dune#2457,
  @rgrinberg)

- Modules may no longer belong to more than one stanza. This was previously
  allowed only in stanzas defined in `jbuild` files. (ocaml/dune#2458, @rgrinberg)

- Remove support for `jbuild-ignore` files. They have been replaced by the the
  `dirs` stanza in `dune` files. (ocaml/dune#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.
  (ocaml/dune#2213, @aalekseyev, @diml)

- Remove support for old style subsystems. Dune will now emit a warning to
  reinstall the library with the old style subsystem. (ocaml/dune#2480, @rgrinberg)

- Add action (with-stdin-from <file> <action>) to redirect input from <file>
  when performing <action>. (ocaml/dune#2487, @nojb)

- Change the automatically generated odoc index to only list public modules.
  This only affects unwrapped libraries (ocaml/dune#2479, @rgrinberg)

- Set up formatting rules by default. They can be configured through a new
  `(formatting)` stanza in `dune-project` (ocaml/dune#2347, fixes ocaml/dune#2315, @emillon)

- Change default target from `@install` to `@all`. (ocaml/dune#2449, fixes ocaml/dune#1220,
  @rgrinberg)

- Include building stubs in `@check` rules. (@rgrinberg, ocaml/dune#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 (ocaml/dune#2541, @diml)

- In `(diff? x y)` action, require `x` to exist and register a
  dependency on that file. (ocaml/dune#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. (ocaml/dune#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. (ocaml/dune#2486,
  @aalekseyev, fixes ocaml/dune#2482)

- `c_flags`, `c_names` and `cxx_names` are now supported in `executable`
  and `executables` stanzas. (ocaml/dune#2562, @nojb)
  Note: this feature has been subsequently extended into a separate
  `foreign_stubs` field. (ocaml/dune#2659, RFC ocaml/dune#2650, @snowleopard)

- Remove git integration from `$ dune upgrade` (ocaml/dune#2565, @rgrinberg)

- Add a `--disable-promotion` to disable all modification to the source
  directory. There's also a corresponding `DUNE_DISABLE_PROMOTION` environment
  variable. (ocaml/dune#2588, fix ocaml/dune#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 (ocaml/dune#2570, @diml)

- Fix incorrect error message when a variable is expanded in static context:
  `%{lib:lib:..}` when the library does not exist. (ocaml/dune#2597, fix ocaml/dune#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. (ocaml/dune#2609, fixes ocaml/dune#2554, @rgrinberg)

- Drop support for `jbuild` and `jbuild-ignore` files (ocaml/dune#2607, @diml)

- 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 <progn> ...). (ocaml/dune#2635, @staronj, @aalekseyev)

- Stop installing the `ocaml-syntax-shims` binary. In order to use
  `future_syntax`, one now need to depend on the `ocaml-syntax-shims`
  package (ocaml/dune#2654, @diml)

- Add support for dependencies that are re-exported. Such dependencies
  are marked with`re_export` and will automatically be provided to
  users of a library (ocaml/dune#2605, @rgrinberg)

- Add a `deprecated_library_name` stanza to redirect old names after a
  library has been renamed (ocaml/dune#2528, @diml)

- Error out when a `preprocessor_deps` field is present but not
  `preprocess` field is. It is a warning with Dune 1.x projects
  (ocaml/dune#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) (ocaml/dune#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. (ocaml/dune#2699, @nojb)

- Do not setup rules for disabled libraries (ocaml/dune#2491, fixes ocaml/dune#2272, @bobot)

- Configurator: filter out empty flags from `pkg-config` (ocaml/dune#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.
  (ocaml/dune#2752, fixes ocaml/dune#2747, @rgrinberg)

- Extend support for foreign sources and archives via the `(foreign_library ...)`
  stanza as well as the `(foreign_stubs ...)` and `(foreign_archives ...)` fields.
  (ocaml/dune#2659, RFC ocaml/dune#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. (ocaml/dune#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. (ocaml/dune#2774, @nojb)

  self-contained bytecode executables whenever this options is available
  (OCaml version >= 4.10) (ocaml/dune#2692, @nojb)

- Add action `(with-accepted-exit-codes <pred> <action>)` to specify the set of

- 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

- 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. (ocaml/dune#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 (ocaml/dune#2329, @diml)

- Change `implicit_transive_deps` to be false. Implicit transitive deps now must
  be manually enabled (ocaml/dune#2306, @rgrinberg)

  is done to prevent the accidental collision with library dependencies of the
  executable. (ocaml/dune#2364, fixes ocaml/dune#2292, @rgrinberg)

- Enable `(explicit_js_mode)` by default. (ocaml/dune#1941, @nojb)

 `--terminal-persistence=clear-on-rebuild`

- Stop symlinking object files to main directory for stanzas defined `jbuild`

- Define (paths ...) fields in (context ...) definitions in order to set or
  extend any PATH-like variable in the context environment. (ocaml/dune#2426, @nojb)

- The `diff` action will always normalize newlines before diffing. Perviousy, it
  would not do this normalization for rules defined in jbuild files. (ocaml/dune#2457,

- Modules may no longer belong to more than one stanza. This was previously
  allowed only in stanzas defined in `jbuild` files. (ocaml/dune#2458, @rgrinberg)

- Remove support for `jbuild-ignore` files. They have been replaced by the the
  `dirs` stanza in `dune` files. (ocaml/dune#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.
  (ocaml/dune#2213, @aalekseyev, @diml)

- Remove support for old style subsystems. Dune will now emit a warning to
  reinstall the library with the old style subsystem. (ocaml/dune#2480, @rgrinberg)

- Add action (with-stdin-from <file> <action>) to redirect input from <file>
  when performing <action>. (ocaml/dune#2487, @nojb)

- Change the automatically generated odoc index to only list public modules.
  This only affects unwrapped libraries (ocaml/dune#2479, @rgrinberg)

- 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. (ocaml/dune#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 (ocaml/dune#2329, @diml)

- 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. (ocaml/dune#2364, fixes ocaml/dune#2292, @rgrinberg)

- Enable `(explicit_js_mode)` by default. (ocaml/dune#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 (ocaml/dune#2440, @rgrinberg)

- Library names are now validated in a strict fashion. Previously, invalid names
  would be allowed for unwrapped libraries (ocaml/dune#2442, @rgrinberg)

- mli only modules must now be explicitly declared. This was previously a
  warning and is now an error. (ocaml/dune#2442, @rgrinberg)

- Modules filtered out from the module list via the Ordered Set Language must
  now be actual modules. (ocaml/dune#2442, @rgrinberg)

- Actions which introduce targets where new targets are forbidden (e.g.
  preprocessing) are now an error instead of a warning. (ocaml/dune#2442, @rgrinberg)

- No longer install a `jbuilder` binary. (ocaml/dune#2441, @diml)

- Stub names are no longer allowed relative paths. This was previously a warning
  and is now an error (ocaml/dune#2443, @rgrinberg).

- Define (paths ...) fields in (context ...) definitions in order to set or
  extend any PATH-like variable in the context environment. (ocaml/dune#2426, @nojb)

- The `diff` action will always normalize newlines before diffing. Perviousy, it
  would not do this normalization for rules defined in jbuild files. (ocaml/dune#2457,
  @rgrinberg)

- Modules may no longer belong to more than one stanza. This was previously
  allowed only in stanzas defined in `jbuild` files. (ocaml/dune#2458, @rgrinberg)

- Remove support for `jbuild-ignore` files. They have been replaced by the the
  `dirs` stanza in `dune` files. (ocaml/dune#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.
  (ocaml/dune#2213, @aalekseyev, @diml)

- Remove support for old style subsystems. Dune will now emit a warning to
  reinstall the library with the old style subsystem. (ocaml/dune#2480, @rgrinberg)

- Add action (with-stdin-from <file> <action>) to redirect input from <file>
  when performing <action>. (ocaml/dune#2487, @nojb)

- Change the automatically generated odoc index to only list public modules.
  This only affects unwrapped libraries (ocaml/dune#2479, @rgrinberg)

- Set up formatting rules by default. They can be configured through a new
  `(formatting)` stanza in `dune-project` (ocaml/dune#2347, fixes ocaml/dune#2315, @emillon)

- Change default target from `@install` to `@all`. (ocaml/dune#2449, fixes ocaml/dune#1220,
  @rgrinberg)

- Include building stubs in `@check` rules. (@rgrinberg, ocaml/dune#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 (ocaml/dune#2541, @diml)

- In `(diff? x y)` action, require `x` to exist and register a
  dependency on that file. (ocaml/dune#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. (ocaml/dune#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. (ocaml/dune#2486,
  @aalekseyev, fixes ocaml/dune#2482)

- `c_flags`, `c_names` and `cxx_names` are now supported in `executable`
  and `executables` stanzas. (ocaml/dune#2562, @nojb)
  Note: this feature has been subsequently extended into a separate
  `foreign_stubs` field. (ocaml/dune#2659, RFC ocaml/dune#2650, @snowleopard)

- Remove git integration from `$ dune upgrade` (ocaml/dune#2565, @rgrinberg)

- Add a `--disable-promotion` to disable all modification to the source
  directory. There's also a corresponding `DUNE_DISABLE_PROMOTION` environment
  variable. (ocaml/dune#2588, fix ocaml/dune#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 (ocaml/dune#2570, @diml)

- Fix incorrect error message when a variable is expanded in static context:
  `%{lib:lib:..}` when the library does not exist. (ocaml/dune#2597, fix ocaml/dune#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. (ocaml/dune#2609, fixes ocaml/dune#2554, @rgrinberg)

- Drop support for `jbuild` and `jbuild-ignore` files (ocaml/dune#2607, @diml)

- 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 <progn> ...). (ocaml/dune#2635, @staronj, @aalekseyev)

- Stop installing the `ocaml-syntax-shims` binary. In order to use
  `future_syntax`, one now need to depend on the `ocaml-syntax-shims`
  package (ocaml/dune#2654, @diml)

- Add support for dependencies that are re-exported. Such dependencies
  are marked with`re_export` and will automatically be provided to
  users of a library (ocaml/dune#2605, @rgrinberg)

- Add a `deprecated_library_name` stanza to redirect old names after a
  library has been renamed (ocaml/dune#2528, @diml)

- Error out when a `preprocessor_deps` field is present but not
  `preprocess` field is. It is a warning with Dune 1.x projects
  (ocaml/dune#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) (ocaml/dune#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. (ocaml/dune#2699, @nojb)

- Do not setup rules for disabled libraries (ocaml/dune#2491, fixes ocaml/dune#2272, @bobot)

- Configurator: filter out empty flags from `pkg-config` (ocaml/dune#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.
  (ocaml/dune#2752, fixes ocaml/dune#2747, @rgrinberg)

- Extend support for foreign sources and archives via the `(foreign_library ...)`
  stanza as well as the `(foreign_stubs ...)` and `(foreign_archives ...)` fields.
  (ocaml/dune#2659, RFC ocaml/dune#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. (ocaml/dune#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. (ocaml/dune#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)`. (ocaml/dune#2851, @diml)

- Allow `ccomp_type` as a variable for evaluating `enabled_if`. (ocaml/dune#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.
  (ocaml/dune#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. (ocaml/dune#2864, @snowleopard)

- Reimplement the bootstrap procedure. The new procedure is faster and
  should no longer stack overflow (ocaml/dune#2854, @dra27, @diml)

- Allow `.opam.template` files to be generated using rules (ocaml/dune#2866, @rgrinberg)
