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!
When input kwarg is missing in i18n.merge_file() it was crashing with a
backtrace because of kwargs['input'][0]. That code was useless anyway
because CustomTarget now uses first output as default name which is what
we need here.
The previous commit bd2fcb268b
accidentally used the wrong var so the param name was missing,
leading to an error of "unrecognized arguments" for the
datadirs parameter value.
There were two allowed kwargs that were unused, I've dropped them for
now, though I need to check if they were documented. If they are then we
need to deprecate them to remove them, otherwise we'll just leave them
removed.
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.
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
Don't just create a .PHONY target which runs a script that magically
generates files ninja doesn't know about. It results in untracked files,
and `meson install` has to run additional commands instead of copying
over files, and then cannot track them to uninstall them later.
I'm not even really sure why it was originally done via a proxy script,
most likely bad legacy design. This is after all one of the oldest
modules...
One side effect of this is that meson doesn't know how to rename
build.CustomTarget files on install (only data files are supported?),
and every file needs to be installed as "domainname.mo" so it must be
named that in-tree too. To prevent clashes, every locale gets its own
locale-specific subdirectory.
Once we are doing that anyway, we can output them to the actual
structure required by the gettext family of functions, and
bindtextdomain() can therefore point to this location if desired. This
might be useful for running localized programs from the build tree.
Re-implement it in backend using the same code path as for
custom_target(). This for example handle setting PATH on Windows when
command is an executable.
On Windows this would fail because of missing DLL:
```
mylib = library(...)
exe = executable(..., link_with: mylib)
meson.add_install_script(exe)
```
The reason is on Windows we cannot rely on rpath to find libraries from
build directory, they are searched in $PATH. We already have all that
mechanism in place for custom_target() using ExecutableSerialisation
class, so reuse it for install/dist/postconf scripts too.
This has bonus side effect to also use exe_wrapper for those scripts.
Fixes: #8187
This patches takes the options work to it's logical conclusion: A single
flat dictionary of OptionKey: UserOptions. This allows us to simplify a
large number of cases, as we don't need to check if an option is in this
dict or that one (or any of 5 or 6, actually).
These are basically doing what mlog.log(..., once=True) does, so lets
just use that. The once argument to mlog is newer, so these probably
should have been changed already.
@permittedKwargs() is basically copying the logic of CustomTarget,
but it is not actually up to date, leading to warnings on perfectly
valid values such as 'build_by_default'.
Use CustomTarget.known_kwargs instead, and only append the specific
kwargs of i18n.merge_file().

using state.subdir will cause / or \ to be inserted into the target name.
Replace them with @ to future-proof it.

As it currently stands, if for whatever reason you have two files you
want to merge with the same output name, it will fail due to multiple
targets with the same name due to the target name being autogenerated
from the output kwarg.

Currently, run_target does not get namespaced for each subproject,
unlike executable and others. This means that two subprojects sharing
the same run_target name cause meson to crash.
Fix this by moving the subproject namespacing logic from the BuildTarget
class to the Target class.
This also adds a "# noqa: F401" comment on an unused "import lzma",
which we are using it in a try/except block that is being used to
check if the lzma module is importable; of course it is unused.
v2: This turned out to be a little tricky.
mesonbuild/modules/__init__.py had the "unused" import:
from ..interpreterbase import permittedKwargs, noKwargs
However, that meant that the various modules could do things like:
from . import noKwargs # "." is "mesonbuild.modules"
Which breaks when you remove __init__.py's "unused" import. I
could have tagged that import with "# noqa: F401", but instead I
chose to have each of the module import directly from
"..interpreterbase" instead of ".".
