Way back in Meson 0.25, support was added to `vala_args` for Files.
Strangely, this was never added to any other language, though it's been
discussed before. For type safety, it makes more sense to handle this in
the interpreter level, and pass only strings into the build IR.
This is accomplished by adding a `depend_files` field to the
`BuildTarget` class (which is not exposed to the user), and adding the
depend files into that field, while converting the arguments to relative
string paths. This ensures both the proper build dependencies happen, as
well as that the arguments are always strings.
Since the previous commit allows for more scenarios with name
collisions, it makes sense to expand the compile command so that it can
also take into account suffixes. i.e. meson compile -C build foo.exe can
now work if the executable has an exe suffix along with being named foo.
When checking target names, meson explictly forbids having multiple
targets with the same name. This is good, but it is strict and it is
impossible to have targets with the same basename and differing suffixes
(e.g. foo and foo.bin) in the same directory. Allow this for executables
by including the suffix (if it exists) in the interal target id. So foo
would be foo@exe and foo.bin would be foo.bin@exe.
Add the `clang-tidy-fix` target to apply clang-tidy fixes to the source
code.
This is done by calling `run-clang-tidy` with `-fix` argument.
Add a test case to run `clang-tidy-fix` and verify the file is changed.

The method can be overridden by setting the `method` key in the wrap
file and always defaults to 'meson'. cmake.subproject() is still needed
in case specific cmake options need to be passed.
This also makes it easier to extend to other methods in the future e.g.
cargo.
It was generating #include with the basename of every header file. That
assumes that every directory where there are headers are also included
into search path when compiling the .c file.
Change to use path relative to current subdir, which can be both in
build or source directory. That means that we assume that when the .c
file is compiled, the target has a include_directories pointing to the
directory where gnome.mkenum_simple() has been called, which is
generally '.' and added automatically.
Also fix type annotation to only allow str and File sources, other types
have never been working, it would require to iterate over custom target
outputs, etc.
Fixes: #7582
Allow macro_name to be speficied as a parameter to configure_file().
This allows C macro-style include guards to be added to
configure_file()'s output when a template file is not given. This change
simplifies the creation of configure files that define macros with
dynamic names and want the C-style include guards.
A standard C library may not exist for cross-compile
environments, thus the existence of <stdio.h> cannot be
guaranteed.
Use <stddef.h> instead, this header contains compiler-specific
defines thus it usually comes from the compiler.
Adds a new method to the compiler object, has_define.
This makes it possible to check if a preprocessor macro/define
is set or not.
This is especially helpful if the define in question is empty,
for example:
#define MESON_EMPTY_DEFINE
This would yield the same results as a missing define with
the existing get_define method, as it would return an empty
string for both cases. Therefore this additional method is
needed.
Allow packagecache to contain already extracted directory to match what
some distro does with Cargo source packages in /usr/share/cargo/registry.
Note that there is no need to lock the cache directory because we
download into a temporary name and atomically rename afterward. It means
we could be downloading the same file twice, but at least integrity is
guaranteed.
Fixes: #12211
Prior to Windows 10, libfoo.a were usually not usable with MSVC. This is
not true any more since Autotools projects built with UCRT produce
libfoo.a that are compatible with MSVC.
This is another reason for using that naming convention in Meson.
`meson setup -Dfoo=bar builddir` command was returning success ignoring
new option values.
This now also update options. It is useful because it means
`meson setup -Dfoo=bar builddir && ninja -C builddir` works regardless
whether builddir already exists or not, and when done in a script,
changing options in the script will automatically trigger a reconfigure
if needed. This was already possible by always passing --reconfigure
argument, but that triggers a reconfigure even when options did not
change.
And in fact *use* typing_extensions, which is sometimes the only way to
get access to TypedDict.
Mostly, reindent almost but not quite an entire file to only define
annotation classes under TYPE_CHECKING.
This reverts commit f52bcaa27f.
It did not pass CI, and was merged anyway because there were two CI
errors in the same cygwin job. The other error was not the fault of this
commit, and since cygwin errors were glossed over because they were
"expected", the presence of a new error *added* by this commit was
overlooked.
Per the meson development policy, PRs which result in CI errors
can/should be reverted at will, no questions asked.
In commit f52bcaa27f a few issues were
added:
- doc typo
- imports for utils.universal are not intended to be directly used, it's
an internal wrapper that exists solely to make mesonlib work well as
it always did while simultaneously allowing `meson --internal`
codepaths to avoid importing anything other than an extremely stripped
down core
- type annotation specific import was imported at runtime scope
This commit adds a new keyword arg to extension_module() that enables
a user to target the Python Limited API, declaring the version of the
limited API that they wish to target.
Two new unittests have been added to test this functionality.
Projects that prefer GNU C but can fallback to ISO C can now set for
example `default_options: 'c_std=gnu11,c11'` and it will use gnu11 when
available, fallback to c11 otherwise. It is an error only if none of the
values are supported by the current compiler.
This allows to deprecate gnuXX values from MSVC compiler, that means
that `default_options: 'c_std=gnu11'` will now print warning with MSVC
but still fallback to 'c11' value. No warning is printed if at least one
of the values is valid, i.e. `default_options: 'c_std=gnu11,c11'`.
In the future that deprecation warning will become an hard error because
`c_std=gnu11` should mean GNU is required, for projects that cannot be
built with MSVC for example.
