Move '-C' option into 'get_always_args' as we always generate C sources.
Add a branch in the dependency management to perform Vala-specific work
of adding '--pkg' and '--target-glib'.
Allow users to specify @CURRENT_SOURCE_DIR@ in generator arguments
to specify the current target source directory.
This is useful when creating protobuf generator objects in sub-directories
because protoc will then generate files in the expected location.
Fixes#1622.
Remove stray semicolon
Update documentation
This adds a set of private flags that are removed from the output of
`llvm-config --cppflags` before storing them. This is unfortunately
necessary since some versions of LLVM include absolute garbage like
'-DNDEBUG' in their CPP flags, and we don't want to pass those.
This implementation is obvious rather than efficient, but it's efficient
enough for our uses I think. It uses `type(self)` to guarantee that it
works even in subclasses or if the name of the class changes.
Refactor to use ExternalProgram for the command instead of duplicating
that code (badly). Also improve messages to say "or not executable"
when a script/command is not found.
Also allow ExternalPrograms to be passed as arguments to
run_command(). The only thing we're doing by preventing that is
forcing people to use prog.path()
The file will always exist by the time run_command() is invoked, so
there is no reason why we should forbid it. Also allow using File
objects as the command to run since strings are also allowed.
We never use preprocessed output anywhere except compiler checks,
so we don't care about the debugging information that it adds.
Just always disable it.
Closes https://github.com/mesonbuild/meson/issues/1726
Provide a proper error message, rather than the current
"Command cannot have '@INPUT0@', since no input files were specified"
which doesn't actually tell us where things are going wrong.
This adds a depdendncy wrapper for llvm-config based on the wxwidgets
dependency. IT handles libs, version, include dir, and the llvm unique
concept of components. These components are individual pieces of the
LLVM library that may or may not be available depending on the platform.
Meson has a common pattern of using 'if len(foo) == 0:' or
'if len(foo) != 0:', however, this is a common anti-pattern in python.
Instead tests for emptiness/non-emptiness should be done with a simple
'if foo:' or 'if not foo:'
Consider the following:
>>> import timeit
>>> timeit.timeit('if len([]) == 0: pass')
0.10730923599840025
>>> timeit.timeit('if not []: pass')
0.030033907998586074
>>> timeit.timeit('if len(['a', 'b', 'c', 'd']) == 0: pass')
0.1154778649979562
>>> timeit.timeit("if not ['a', 'b', 'c', 'd']: pass")
0.08259823200205574
>>> timeit.timeit('if len("") == 0: pass')
0.089759664999292
>>> timeit.timeit('if not "": pass')
0.02340641999762738
>>> timeit.timeit('if len("foo") == 0: pass')
0.08848102600313723
>>> timeit.timeit('if not "foo": pass')
0.04032287199879647
And for the one additional case of 'if len(foo.strip()) == 0', which can
be replaced with 'if not foo.isspace()'
>>> timeit.timeit('if len(" ".strip()) == 0: pass')
0.15294511600222904
>>> timeit.timeit('if " ".isspace(): pass')
0.09413968399894657
>>> timeit.timeit('if len(" abc".strip()) == 0: pass')
0.2023209120015963
>>> timeit.timeit('if " abc".isspace(): pass')
0.09571301700270851
In other words, it's always a win to not use len(), when you don't
actually want to check the length.
Use a titlecase for arbitrary language, this was we don't have 'C' in
lowercase.
Rename 'Static linking library $out' for 'Linking static target $out.'.
Add missing punctuation.
When cross compiling and looking for moc/uic/rcc you really want the
host binary.
Still fall back to QT_INSTALL_BINS as it appears that's the only
variable available with qt4.
It's much faster to do 'if a in dict' instead of 'if a in dict.keys()',
since the latter constructs an iterator and walks that iterator and then
tests equality at each step, and the former does a single hash lookup.
The intel fortran compiler "ifort" was not listed in the list of
default fortran compilers. This caused it to not be found unless
explicitly set via the FC.
This uses the ABC's in collections to implement an OrderedSet class.
Internally an OrderedDict is still wrapped so that the ordering is
maintained, this adds the full interface and behavior of an Set, but
with ordering by first insertion.
Using Meson from outside a git repo results in an error when trying to
resolve submodule subprojects. Running git from inside subproject root
should be enough to fix it.

After an initial checkout, submodules aren’t initialized and thus trying
to update them fails.
