Since it cannot resolve `import typing as T` in order to figure out that
T.* is doing annotation-worthy stuff.
Since T.cast('Foo') is not actually using Foo except in an annotation
context (due to being a string) it requires extra work to resolve, and
the only thing that would currently work is actually using
'typing.cast'. However, we have decided to not use it except as T...
Since this import is only imported during mypy it's not so bad to noqa
it.
It is imported from a subpackage in __init__ alongside a big list of
other things which are all exported. And elsewhere, this import is
re-imported by other code. It's pretty clearly an oversight that it
didn't get added to __all__
Alias commands did not work with the vs backend, due to trying to access
target.command[0] with an empty command. Fix this by just not emitting a
CustomBuild node for alias targets - the project references are enough to
trigger the necessary actions.

It's broken in various circumstances, no one seems to actually use it,
CI doesn't test it, no one is committed to maintaining it, etc. etc.
etc.
Also, projects doing trivially reasonable things, such as generating
"foo/util.py" and "bar/util.py", create clashing output names. This will
never, ever, ever, ever work with layout=flat.

Until we invoke interpreter.Interpreter(b, ...) the coredata options
still have their default values and thus cannot be used sensibly.
Currently the warning never shows (other than, unsurprising in
retrospect, during --internal regenerate).
In commit 3c4c7d0429 the qresource
variable stopped being overwritten with a mesonlib.File, which is
reasonable. However, one call site for it which relied on being a built
file did not get renamed when needed.
Make the build target use the built file.
The clang compiler now reimplements and re-checks the c_std and cpp_std
options in order to use them for objc as well, but it didn't
consistently support the same options. First it completely excluded all
the gnu ones, and then it added a handful of them but not for C++.
Be fully consistent -- or at least as consistent as we can be, given a
minimally working fix. (The C/C++ compiler mixin actually gates
different stds depending on detected clang version, we do not do that
here.)

Dependencies are currently printed as
[<mesonbuild.mlog.AnsiDecorator object at 0x7faa85aeac70>, ' ', <mesonbuild.mlog.AnsiDecorator object at 0x7faa85aeab50>]
This was introduced in commit adb1b2f3f6, due to
an incorrect type annotation on the AnsiText constructor. Fix both the
annotation and the usage.

Allow using the links method to test that the C++ driver (e.g. g++) can be used to
link C objects. One usecase is that the C compiler's libsanitizer might not be
compatible with the one included by the C++ driver.
This is theoretically backwards-incompatible, but it should be treated as a
bugfix in my opinion. There is no way in Meson to compile a .c file with the
C++ driver as part of a build target, therefore there would be no reason to
do something like meson.get_compiler(meson.get_compiler('cpp').links(files('main.c')).
Fixes: #7703
In some cases, link tests would like to use objects provided by a compiler
for a different language, for example linking a C object file with a C++
compiler. This kind of scenario is what link_language is for, but it is
impossible to test that it works with a linker test.
This patch implements the required support in the Compiler class. The
source code compiler is passed to the Compiler.links method as an
argument.
Fixes various inconsistencies:
- gitattributes is respected
- export-subst
- export-ignore
- submodules with relative paths are not checked out relative to the
local clone (which does not work anyway)
- no need to manually remove gitfiles with inaccurate heuristics

"ERROR: Git program not found" is both highly true, and somewhat
inscrutable. Sure, looking at the line number you can basically figure
out that subproject('something') must somehow need git to operate, but
that may not be immediately obvious.
Make mention of the fact that it is needed to "download foo.wrap".
Fixes#7764
It is a commonly needed information to help debugging build issues. We
already were printing options with non-default value at the end of the
configure but outside of the summary.
Keeping the list of user defined options in the interpreter will also in
the future be useful to use new default value on reconfigure.
And more accurate too, TBH. Currently it says it is building "lang.mo",
even though it is actually building "domain.mo" inside
lang/LC_MESSAGES/.
Since meson loudly complains if I try to name the display name
"lang/domain.mo", name it with a dash instead of a slash. The actual
name isn't a priority here IMO, and this is nicely readable.
* compilers: improve docstring to `get_compiler_check_args()`
There was an incomplete list, which wasn't useful as it now takes an
enum anyway. Also add a new entry to the list of reasons to use this
function.
* clang: Add -Werror=implicit-function-declarations to check_args
Unlike GCC, clang warns but doesn't error when an implicit function
declaration happens. This means in checks like
`compiler.has_header_symbol('string.h', 'strlcat')` (on Linux, at least)
that GCC will fail, as there is no such function; clang will emit a
warning, but since it exists with a 0 status Meson interprets that as
success. To fix this, add `-Werror=implicit-function-declarations` to
clang's check arguments.
There seems to be something specific about functions that _may_ exist in
a header on a given system, as `cc.has_header_symbol('string.h',
'foobar')` will return false with clang, but `strlcat` will return true,
even though it's not defined. It is however, defined in some OSes, like
Solaris and the BSDs.
Fixes#9140
Removed in commit 487d45c1e5 but perhaps
it should not have -- people may have been depending on ensuring those
are built somehow. Even though the internal implementation changed and
it is now built by the all target, let's keep the old target around too.
Now it just aliases the actual build rules, though.
Users may wish to make use of these files for their own purposes.
For example, the -pot and -update-po pseudo targets could be reused in
an alias_target(), and at least one person wanted to reuse the built .mo
files as custom_target input.
Fixes#6227
This simplifies things for us, as we don't have to have threading
imported for no other reason, and we can remove the
`an_unpicklable_object` from the Interpreter and mesonlib, since there
was only one user of this.
This caught a couple of cases of us doing:
```python
for i in range(len(x)):
v = x[i]
```
which are places to use enumerate instead.
It also caught a couple of cases of:
```python
assert len(x) == len(y)
for i in range(len(x)):
xv = x[i]
yv = y[i]
```
Which should instead be using zip()
```python
for xv, yv in zip(x, y):
...
```
