We validate a few things here, such as the non-presence of '@INPUT' in
an output name. These got moved out of the CustomTarget constructor in
commit 11f9638035 and into KwargInfo, but
only for kwargs that took multiple values. This caused configure_file()
and unstable_rust.bindgen() to stop checking for this.
Add a shared single-output KW and use it in both places. This now
dispatches to _output_validator.
configure_file now validates subdirectories in output names the same way
we do elsewhere, directly in the typed_kwargs and by specifying the
erroring kwarg.
Previously subprojects inherited languages already added by main
project, or any previous subproject. This change to have a list of
compilers per interpreters, which means that if a subproject does not
add 'c' language it won't be able to compile .c files any more, even if
main project added the 'c' language.
This delays processing list of compilers until the interpreter adds the
BuildTarget into its list of targets. That way the interpreter can add
missing languages instead of duplicating that logic into BuildTarget for
the cython case.
Because we don't want to pass the Interpreter kwargs into the build
layer. This turned out to be a mega commit, as there's really on elegant
way to make this change in an incremental way. On the nice side, mypy
made this change super easy, as nearly all of the calls to
`CustomTarget` are fully type checked!
It also turns out that we're not handling install_tags in custom_target
correctly, since we're not converting the boolean values into Optional
values!
Make the handling of bindgen inputs consistent with the inputs and outputs of
source_strings_to_files.
However, for the first source argument reject anything that cannot
possibly be an header file. This also fixes a mypy failure from the next
patch, since ExtractedObjects does not have a zero-argument get_outputs
method.

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.
- 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.
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
we have two functions to do the exact same thing, and they're basically
implemented the same way. Instead, let's just use the BuildTarget one,
as it's more generally available.
Like other language specific modules this module is module for holding
rust specific helpers. This commit adds a test() function, which
simplifies using rust's internal unittest mechanism.
Rust tests are generally placed in the same code files as they are
testing, in contrast to languages like C/C++ and python which generally
place the tests in separate translation units. For meson this is
somewhat problematic from a repetition point of view, as the only
changes are generally adding --test, and possibly some dependencies.
The rustmod.test() method provides a mechanism to remove the repatition:
it takes a rust target, copies it, and then addes the `--test` option,
then creates a Test() target with the `rust` protocol. You can pass
additional dependencies via the `dependencies` keyword. This all makes
for a nice, DRY, test definition.
