Custom objects returned by modules must be subclass of ModuleObject and
have the state argument in its methods.
Add MutableModuleObject base class for objects that needs to be deep
copied on assignation.
The only advantage they have is they have the interpreter in arguments,
but it's already available as self.interpreter. We should discourage
usage of the interpreter API and rely on ModuleState object instead in
the future.
This also lift the restriction that a module method cannot add build
targets, but that was not enforced for snippet methods anyway (and some
modules were doing it) and it's really loose restriction as it should
check for many other things if we wanted to make it consistent.
We need to pass any generated sources down the CustomTarget
inititalizers so that they will generate a dependency correctly,
otherwise we get race conditions.
We need to escape space in variables that gets into cflags or libs
because otherwise we cannot split compiler args when paths contains
spaces. But custom variables are unlikely to be path that gets used in
cflags/libs, and escaping them cause regression in GStreamer that use
space as separator in a list variable.
install_scripts used to replace @BUILD_ROOT@ and @SOURCE_ROOT@ but it
was not documented and got removed in Meson 0.58.0. gnome.gtkdoc() was
relying on that behaviour, but it has always been broken in the case the
source or build directory contains spaces.
Fix this by changing get_include_args() to substitue paths directly
which will then get escaped correctly.
Add a unit test that builds GObject documentation which is where this
issue has been spotted.

With this change File objects created with the builtin files() function
can be used with the fs submodule like normal strings.
All methods that seem reasonable support FileOrSting arguments.
For example fs.exists() still only takes str arguments because meson
already ensures that File objects do exist when creating them with files().
Each user facing function of the fs module has an additional FeatureNew
check when used with File objects.
The test cases for fs are extended appropriately with tests for File objects.
Cross-compiling and generating gobject-introspection isn't trivial, but
with wrapper scripts that call qemu-user it's perfectly doable[1].
Currently looking up the gobject-introspection pkgconfig is done as a
native dependency, which means in cross-compilation environments this
is not the right paths (wrong library path, for example).
Solve this by generalisiing _get_native_dep() to _get_dep(native) and
asking for the host gobject-introspection instead.

If an invalid resource path is specified, then an uncaught python
exception occurs, and a backtrace is shown. Throw a MesonException
instead to produce a cleaner error message.
Some variables are reserved because meson set them automatically. But we
are not setting them for dataonly pc files, so there is no reason to
reserve them.

Currently the Qt Dependencies still use the old "combined" method for
dependencies with multiple ways to be found. This is problematic as it
means that `get_variable()` and friends don't work, as the dependency
can't implement any of those methods. The correct solution is to make
use of multiple Dependency instances, and a factory to tie them
together. This does that.
To handle QMake, I've leveraged the existing config-tool mechanism,
which allows us to save a good deal of code, and use well tested code
instead of rolling more of our own code.
The one thing this doesn't do, but we probably should, is expose the
macOS ExtraFrameworks directly, instead of forcing them to be found
through QMake. That is a problem for another series, and someone who
cares more about macOS than I do.
It's a method on the QtDependeny that exists purely for the consumption
of the qt module (in the form, return some stuff the module makes into
an instance variable). So put it where it actually belongs, and pass the
qt dependency into it.
Dependencies is already a large and complicated package without adding
programs to the list. This also allows us to untangle a bit of spaghetti
that we have.
All changes were created by running
"pyupgrade --py3-only --keep-percent-format"
and committing the results. I have not touched string formatting for
now.
- use set literals
- simplify .format() parameter naming
- remove __future__
- remove default "r" mode for open()
- use OSError rather than compatibility aliases
- remove stray parentheses in function(generator) scopes
- ModuleState is now a real class that will have methods in the future
for actions modules needs, instead of using interpreter internal API.
- New ModuleObject base class, similar to InterpreterObject, that should
be used by all objects returned by modules. Its methods gets the
ModuleState passed as first argument. It has a `methods` dictionary to
define what is public API that can be called from build definition.
- Method return value is not required to be a ModuleReturnValue any
more, it can be any type that interpreter can holderify, including
ModuleObject.
- Legacy module API is maintained until we port all modules.
In the future modules should be updated:
- Use methods dict.
- Remove snippets.
- Custom objects returned by modules should all be subclass of
ModuleObject to get the state iface in their methods.
- Modules should never call into interpreter directly and instead state
object should have wrapper API.
- Stop using ModuleReturnValue in methods that just return simple
objects like strings. Possibly remove ModuleReturnValue completely
since all objects that needs to be processed by interpreter (e.g.
CustomTarget) should be created through ModuleState API.
Rather than having to manually build the locale aware man paths with
`install_data('foo.fr.1', install_dir: join_paths(get_option('mandir'), 'fr', 'man1'), rename: 'foo.1')`
Support doing
`install_man('foo.fr.1', locale: 'fr')`
By default all subprojects are installed. If --skip-subprojects is given
with no value only the main project is installed. If --skip-subprojects
is given with a value, it should be a coma separated list of subprojects
to skip and all others will be installed.

This has a couple of advantages over rolling it by hand:
1. it correctly handles include_directories objects, which is always
handy
2. it correctly generates a depfile for you, which makes it more
reliable
3. it requires less typing
Re-implement it in backend using the same code path as for
custom_target(). This for example handle setting PATH on Windows when
command is an executable.
Various GNOME projects have scripts that does similar task, better do it
directly in meson. This ensures it's done correctly regarding usage of
subprojects and pkg-config. See for example this gtk bug:
https://gitlab.gnome.org/GNOME/gtk/-/issues/3626.
Fixes: #8268
Following #7890, this patch introduces the ability to read the contents
of a file to the fs module.
This patch introduces the ability to read files at configure time, but
has some restrictions:
- binary files are not supported (I don't think this will prove a
problem, and if people are wanting to do something with binary
files, they should probably be shelling out to their own script).
- Only files outside the build directory allowed. This limitation
should prevent build loops.
Given that reading an arbitrary file at configure time can affect the
configuration in almost arbitrary ways, meson should force a reconfigure
when the given file changes. This is non-configurable, but this can
easily be changed with a future keyword argument.
On Windows this would fail because of missing DLL:
```
mylib = library(...)
exe = executable(..., link_with: mylib)
meson.add_install_script(exe)
```
The reason is on Windows we cannot rely on rpath to find libraries from
build directory, they are searched in $PATH. We already have all that
mechanism in place for custom_target() using ExecutableSerialisation
class, so reuse it for install/dist/postconf scripts too.
This has bonus side effect to also use exe_wrapper for those scripts.
