There are cases where we need to specify arguments to gtkdoc-mkdb, like
telling it to scan extensions that are not '.h' and '.c'. Let's add a
new named argument to gnome.gtkdoc(), as well as the plumbing needed for
the gtk-doc helper script.
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.
Grammatically, this full stop isn't needed and with file names it has a
potential to be confusing:
Installing /foo/bar/filename.1 to /foo/bar/dirname.
The full stop caused me to do a double-take more than once, so let's drop it.
'gtkdoc-scangobj' script was recently ported to Python (it was Perl), and it now requires providing '--type' option to specify the name of the file to store the types in. Without this option, 'gtkdockelper' will exit with error status 2 and will throw a message "gtkdoc-scangobj: error: unrecognized arguments: <typefile>"
'test cases/common/12 data' and 'test cases/common/66 install subdir' both
try to install something as 'root'. This user doesn't exist on Cygwin.
Perhaps we should automatically convert this to some other user, but it's
not clear which. For real projects, it's possibly better for the meson.build
to explicitly handle this...
'test cases/common/12 data' also tries to install something with GID 0.
There's no guarantee this group exists.
Points to the `mesonintrospect.py` script corresponding to the
currently-running version of Meson.
Includes a test for all three methods of running scripts/commands.
Closes https://github.com/mesonbuild/meson/issues/1385
With the 'install_mode' kwarg, you can now specify the file and
directory permissions and the owner and the group to be used while
installing. You can pass either:
* A single string specifying just the permissions
* A list of strings with:
- The first argument a string of permissions
- The second argument a string specifying the owner or
an int specifying the uid
- The third argument a string specifying the group or
an int specifying the gid
Specifying `false` as any of the arguments skips setting that one.
The format of the permissions kwarg is the same as the symbolic
notation used by ls -l with the first character that specifies 'd',
'-', 'c', etc for the file type omitted since that is always obvious
from the context.
Includes unit tests for the same. Sadly these only run on Linux right
now, but we want them to run on all platforms. We do set the mode in the
integration tests for all platforms but we don't check if they were
actually set correctly.
Set the rules for the symlinking on the target itself, and then reuse
that information while generating aliases during the build, and then
pass it to the install script too.
At installation, if the executable is a ELF file, we try to fix the
dependencies in the binary section.
If a executable has been compiled with the --static flag, there is
no .dynamic section in the ELF binary and so we need to handle this case.

The script will manually delete all custom_target outputs that are
directories instead of files. This is needed because on platforms other
than Windows, Ninja only deletes directories while cleaning if they are
empty.
Closes#1220
This is useful in many cases where the list of files cannot be known in
advance and is just dumped inside a directory. For example when
generating documentation with doxygen and other tools that we don't have
built-in support for.
Includes a test for the same.
Closes#893
In the case of subproject we will properly setup the --subdir argument
but the MESON_SUBDIR is never adapted and will point to an empty string
leading to the following backtrace when building `gst-build`:
