+name: meson
+long_name: Meson object
+description: |
+  The `meson` object allows you to introspect various properties of the
+  system. This object is always mapped in the `meson` variable.

+methods:
+  - name: add_dist_script
+    returns: void
+    since: 0.48.0
+    description: |
+      Causes the script given as argument to run during `dist`
+      operation after the
+      distribution source has been generated but before it is
+      archived. Note that this runs the script file that is in the
+      _staging_ directory, not the one in the source directory. If the
+      script file can not be found in the staging directory, it is a hard
+      error. The `MESON_DIST_ROOT` environment variables is set when dist scripts is
+      run.
+
+      *(since 0.54.0)* The `MESON_SOURCE_ROOT` and `MESON_BUILD_ROOT`
+      environment variables are set when dist scripts are run. They are path to the
+      root source and build directory of the main project, even when the script
+      comes from a subproject.
+
+      *(since 0.58.0)* This command can be invoked from a subproject, it was a hard
+      error in earlier versions. Subproject dist scripts will only be executed
+      when running `meson dist --include-subprojects`. `MESON_PROJECT_SOURCE_ROOT`,
+      `MESON_PROJECT_BUILD_ROOT` and `MESON_PROJECT_DIST_ROOT` environment
+      variables are set when dist scripts are run. They are identical to
+      `MESON_SOURCE_ROOT`, `MESON_BUILD_ROOT` and `MESON_DIST_ROOT` for main project
+      scripts, but for subproject scripts they have the path to the root of the
+      subproject appended, usually `subprojects/<subproject-name>`.

+
+  - name: add_install_script
+    returns: void
+    description: |
+      Causes the script given as an argument to be run during the install step,
+      this script  will have the environment variables `MESON_SOURCE_ROOT`,
+      `MESON_BUILD_ROOT`, `MESON_INSTALL_PREFIX`,
+      `MESON_INSTALL_DESTDIR_PREFIX`, and `MESONINTROSPECT` set.
+      All positional arguments are passed as parameters.
+
+      *(since 0.54.0)* If `meson install` is called with the `--quiet` option, the
+      environment variable `MESON_INSTALL_QUIET` will be set.
+
+      Meson uses the `DESTDIR` environment variable as set by the
+      inherited environment to determine the (temporary) installation
+      location for files. Your install script must be aware of this while
+      manipulating and installing files. The correct way to handle this is
+      with the `MESON_INSTALL_DESTDIR_PREFIX` variable which is always set
+      and contains `DESTDIR` (if set) and `prefix` joined together. This
+      is useful because both are usually absolute paths and there are
+      platform-specific edge-cases in joining two absolute paths.
+
+      In case it is needed, `MESON_INSTALL_PREFIX` is also always set and
+      has the value of the `prefix` option passed to Meson.
+
+      `MESONINTROSPECT` contains the path to the introspect command that
+      corresponds to the `meson` executable that was used to configure the
+      build. (This might be a different path than the first executable
+      found in `PATH`.) It can be used to query build configuration. Note
+      that the value will contain many parts, f.ex., it may be `python3
+      /path/to/meson.py introspect`. The user is responsible for splitting
+      the string to an array if needed by splitting lexically like a UNIX
+      shell would. If your script uses Python, `shlex.split()` is the
+      easiest correct way to do this.

+  - `@BASENAME@`: the input filename, with extension removed
+  - `@PRIVATE_DIR@` *(since 0.50.1)*: path to a directory where the custom target must store all its intermediate files.
+  - `@SOURCE_ROOT@`: the path to the root of the source tree. Depending on the backend,
+    this may be an absolute or a relative to current workdir path.
+  - `@BUILD_ROOT@`: the path to the root of the build tree. Depending on the backend,
+    this may be an absolute or a relative to current workdir path.
+  - `@CURRENT_SOURCE_DIR@`: this is the directory where the currently
+    processed meson.build is located in.  Depending on the backend,
+    this may be an absolute or a relative to current workdir path.
+
+  *(since 0.47.0)* The `depfile` keyword argument also accepts the

+name: dependency
+returns: dep
+description: |
+  Finds an external dependency (usually a library installed on your
+  system) with the given name with `pkg-config` and [with
+  CMake](Dependencies.md#cmake) if `pkg-config` fails. Additionally,
+  frameworks (OSX only) and [library-specific fallback detection
+  logic](Dependencies.md#dependencies-with-custom-lookup-functionality)
+  are also supported.
+
+  Dependencies can also be resolved in two other ways:
+
+  * if the same name was used in a `meson.override_dependency` prior to
+    the call to `dependency`, the overriding dependency will be returned
+    unconditionally; that is, the overriding dependency will be used
+    independent of whether an external dependency is installed in the system.
+    Typically, `meson.override_dependency` will have been used by a
+    subproject.
+
+  * by a fallback subproject which, if needed, will be brought into the current
+    build specification as if [`subproject()`](#subproject) had been called.
+    The subproject can be specified with the `fallback` argument.  Alternatively,
+    if the `fallback` argument is absent, *since 0.55.0* Meson can
+    automatically identify a subproject as a fallback if a wrap file
+    [provides](Wrap-dependency-system-manual.md#provide-section) the
+    dependency, or if a subproject has the same name as the dependency.
+    In the latter case, the subproject must use `meson.override_dependency` to
+    specify the replacement, or Meson will report a hard error.  See the
+    [Wrap documentation](Wrap-dependency-system-manual.md#provide-section)
+    for more details.  This automatic search can be controlled using the
+    `allow_fallback` keyword argument.
+
+  If `dependency_name` is `''`, the dependency is always not found. So
+  with `required: false`, this always returns a dependency object for
+  which the `found()` method returns `false`, and which can be passed
+  like any other dependency to the `dependencies:` keyword argument of a
+  `build_target`. This can be used to implement a dependency which is
+  sometimes not required e.g. in some branches of a conditional, or with
+  a `fallback:` kwarg, can be used to declare an optional dependency
+  that only looks in the specified subproject, and only if that's
+  allowed by `--wrap-mode`.
+
+  The returned object [[@dep]] also has additional methods.
+
+notes:
+  - This function supports additional [library-specific](Dependencies.md#dependencies-with-custom-lookup-functionality)
+    keyword arguments that may also be accepted (e.g. `modules` specifies submodules to use for
+    dependencies such as Qt5 or Boost. `components` allows the user to manually
+    add CMake `COMPONENTS` for the `find_package` lookup)

+
+  allow_fallback:
+    type: bool
+    since: 0.56.0
+    description: |
+      Specifies whether Meson should automatically pick a fallback subproject
+      in case the dependency
+      is not found in the system.  If `true` and the dependency is not found
+      on the system, Meson will fallback to a subproject that provides this
+      dependency. If `false`, Meson will not fallback even if a subproject
+      provides this dependency.  By default, Meson will do so if `required`
+      is `true` or  [`enabled`](Build-options.md#features); see the [Wrap
+      documentation](Wrap-dependency-system-manual.md#provide-section)
+      for more details.
+
+  fallback:
+    type: list[str] | str
+    description: |
+      Manually specifies a subproject fallback
+      to use in case the dependency is not found in the system.
+      This is useful if the automatic search is not applicable or if you
+      want to support versions of Meson older than 0.55.0.  If the value is an
+      array `['subproj_name', 'subproj_dep']`, the first value is the name
+      of the subproject and the second is the variable name in that
+      subproject that contains a dependency object such as the return
+      value of [[declare_dependency]] or
+      [[dependency]], etc. Note that this means the
+      fallback dependency may be a not-found dependency, in which
+      case the value of the `required:` kwarg will be obeyed.
+      *Since 0.54.0* the value can be a single string, the subproject name;
+      in this case the subproject must use
+      `meson.override_dependency('dependency_name', subproj_dep)`
+      to specify the dependency object used in the superproject.
+      If the value is an empty list, it has the same effect as

+
+  version:

+      `>1.0.0`, `<=2.3.5` or `3.1.4` for exact matching.
+      You can also specify multiple restrictions by passing a list to this
+      keyword argument, such as: `['>=3.14.0', '<=4.1.0']`.

+description: |
+  `program_name` here is a string that can be an executable or script
+  to be searched for in `PATH` or other places inside the project.
+  The search order is:
+
+  1. Program overrides set via [[meson.override_find_program]]
+  1. [`[provide]` sections](Wrap-dependency-system-manual.md#provide-section)
+    in subproject wrap files, if [`wrap_mode`](Builtin-options.md#core-options) is
+    set to `forcefallback`
+  1. [`[binaries]` section](Machine-files.md#binaries) in your machine files
+  1. Directories provided using the `dirs:` kwarg (see below)
+  1. Project's source tree relative to the current subdir
+    - If you use the return value of [[configure_file]], the
+      current subdir inside the build tree is used instead
+  1. `PATH` environment variable
+  1. [`[provide]` sections](Wrap-dependency-system-manual.md#provide-section) in
+    subproject wrap files, if [`wrap_mode`](Builtin-options.md#core-options) is
+    set to anything other than `nofallback`
+
+  Meson will also autodetect scripts with a shebang line and run them
+  with the executable/interpreter specified in it both on Windows
+  (because the command invocator will reject the command otherwise) and
+  Unixes (if the script file does not have the executable bit set).
+  Hence, you *must not* manually add the interpreter while using this
+  script as part of a list of commands.
+
+  If you need to check for a program in a non-standard location, you can
+  just pass an absolute path to `find_program`, e.g.
+
+  ```meson
+  setcap = find_program('setcap', '/usr/sbin/setcap', '/sbin/setcap', required : false)
+  ```
+
+  It is also possible to pass an array to `find_program` in case you
+  need to construct the set of paths to search on the fly:
+
+  ```meson
+  setcap = find_program(['setcap', '/usr/sbin/setcap', '/sbin/setcap'], required : false)
+  ```

+name: generator
+returns: generator
+description: |
+  See also: [[custom_target]]
+
+  This function creates a [[@generator]] object that can
+  be used to run custom compilation commands. The only positional
+  argument is the executable to use. It can either be a self-built
+  executable or one returned by find_program.
+
+  The template strings passed to all the keyword arguments accept
+  the following special substitutions:
+
+  - `@PLAINNAME@`: the complete input file name, e.g: `foo.c` becomes `foo.c` (unchanged)
+  - `@BASENAME@`: the base of the input filename, e.g.: `foo.c.y` becomes `foo.c` (extension is removed)
+
+  Each string passed to the `output` keyword argument *must* be
+  constructed using one or both of these two substitutions.
+
+  In addition to the above substitutions, the `arguments` keyword
+  argument also accepts the following:
+
+  - `@OUTPUT@`: the full path to the output file
+  - `@INPUT@`: the full path to the input file
+  - `@DEPFILE@`: the full path to the depfile
+  - `@SOURCE_DIR@`: the full path to the root of the source tree
+  - `@CURRENT_SOURCE_DIR@`: this is the directory where the currently processed meson.build is located in
+  - `@BUILD_DIR@`: the full path to the root of the build dir where the output will be placed
+
+  NOTE: Generators should only be used for outputs that will ***only***
+  be used as inputs for a [[build_target]] or a [[custom_target]].
+  When you use the processed output of a
+  generator in multiple targets, the generator will be run multiple
+  times to create outputs for each target. Each output will be created
+  in a target-private directory `@BUILD_DIR@`.
+
+  If you want to generate files for general purposes such as for
+  generating headers to be used by several sources, or data that will be
+  installed, and so on, use a [[custom_target]] instead.

+name: summary
+returns: void
+since: 0.53.0
+description: |
+  This function is used to summarize build configuration at the end of the build
+  process. This function provides a way for projects (and subprojects) to report
+  this information in a clear way.
+
+  The content is a series of key/value pairs grouped into sections. If
+  the section keyword argument is omitted, those key/value pairs are
+  implicitly grouped into a section with no title. key/value pairs can
+  optionally be grouped into a dictionary, but keep in mind that
+  dictionaries does not guarantee ordering. `key` must be string,
+  `value` can be:
+
+  - an integer, boolean or string
+  - *since 0.57.0* an external program or a dependency
+  - *since 0.58.0* a feature option
+  - a list of those.
+
+  Instead of calling summary as `summary(key, value)`, it is also possible to
+  directly pass a dictionary to the [[summary]] function, as seen in the example
+  below.
+
+  `summary()` can be called multiple times as long as the same
+  section/key pair doesn't appear twice. All sections will be collected
+  and printed at the end of the configuration in the same order as they
+  have been called.
+
+example: |
+  Example `meson.build`:
+  ```meson
+  project('My Project', version : '1.0')
+  summary({'bindir': get_option('bindir'),
+          'libdir': get_option('libdir'),
+          'datadir': get_option('datadir'),
+          }, section: 'Directories')
+  summary({'Some boolean': false,
+          'Another boolean': true,
+          'Some string': 'Hello World',
+          'A list': ['string', 1, true],
+          }, section: 'Configuration')
+  ```
+
+  Output:
+  ```
+  My Project 1.0
+
+    Directories
+      prefix         : /opt/gnome
+      bindir         : bin

+  Defines a test to run with the test harness. Takes two positional
+  arguments, the first is the name of the test and the second is the
+  executable to run. The executable can be an [[@exe]] object returned by
+  [[executable]] or an [[@external_program]] object] returned by
+  [[find_program]].
+
+  *(since 0.55.0)* When cross compiling, if an exe_wrapper is needed and
+  defined the environment variable `MESON_EXE_WRAPPER` will be set to
+  the string value of that wrapper (implementation detail: using
+  `mesonlib.join_args`). Test scripts may use this to run cross built
+  binaries. If your test needs `MESON_EXE_WRAPPER` in cross build
+  situations it is your responsibility to return code 77 to tell the
+  harness to report "skip".
+
+  By default, environment variable
+  [`MALLOC_PERTURB_`](http://man7.org/linux/man-pages/man3/mallopt.3.html)
+  is automatically set by `meson test` to a random value between 1..255.
+  This can help find memory leaks on configurations using glibc,
+  including with non-GCC compilers. However, this can have a performance
+  impact, and may fail a test due to external libraries whose internals
+  are out of the user's control. To check if this feature is causing an
+  expected runtime crash, disable the feature by temporarily setting
+  environment variable `MALLOC_PERTURB_=0`. While it's preferable to
+  only temporarily disable this check, if a project requires permanent
+  disabling of this check in meson.build do like:
+
+  ```meson
+  nomalloc = environment({'MALLOC_PERTURB_': '0'})
+
+  test(..., env: nomalloc, ...)
+  ```
+
+  Defined tests can be run in a backend-agnostic way by calling
+  `meson test` inside the build dir, or by using backend-specific
+  commands, such as `ninja test` or `msbuild RUN_TESTS.vcxproj`.

+example: |
+  ```meson

+
+  # MY_PATH will be '0:1:2:3'
+  env.set('MY_PATH', '1')
+  env.append('MY_PATH', '2')
+  env.append('MY_PATH', '3')
+  env.prepend('MY_PATH', '0')
+  ```

+    the value `BOB` and plain `BAR;BAZ` if the value was not defined.
