Now that we bumped our meson requirement, meson is complaining about
several features now deprecated even in the minimum required meson
version:
s/meson.source_root/meson.project_source_root/ to fix:
> WARNING: Project targets '>=0.56.0' but uses feature deprecated since '0.56.0': meson.source_root. use meson.project_source_root() or meson.global_source_root() instead.
s/meson.build_root/meson.project_build_root/ to fix:
> WARNING: Project targets '>=0.56.0' but uses feature deprecated since '0.56.0': meson.build_root. use meson.project_build_root() or meson.global_build_root() instead.
Fixing using path() on xdg_email and python ExternalProgram variables:
> WARNING: Project targets '>=0.56.0' but uses feature deprecated since '0.55.0': ExternalProgram.path. use ExternalProgram.full_path() instead
s/get_pkgconfig_variable *(\([^)]*\))/get_variable(pkgconfig: \1)/ to
fix:
> WARNING: Project targets '>=0.56.0' but uses feature deprecated since '0.56.0': dependency.get_pkgconfig_variable. use dependency.get_variable(pkgconfig : ...) instead
… Windows installer localization.
There are kind of 2 separate bugs here:
- Direct i18n.gettext() to the proper data directory where to find the
ITS file. Otherwise `meson compile gimp30-windows-installer-pot` and
`meson compile gimp30-windows-installer-update-po` complained about
not knowing XML and falling back to C, which is obviously a problem:
> /usr/bin/xgettext: warning: file 'build/windows/installer/lang/setup.isl.xml.in' extension 'xml' is unknown; will try C
- Set gt:escapeRule to "no" in the ITS file, otherwise the XML entity is
kept as-is in the po file (i.e. "&" stays "&" inside the po
files), but it's considered as raw text when merged back to XML, i.e.
that the '&' is properly converted to a XML entity, so we end up with
a double escape "&".
Now the po file will have a '&' which will still be converted to XML
entity at merge time. This is actually most likely better than asking
translators to handle XML entities themselves (with the possibility to
make typos and break the XML entity).
See https://savannah.gnu.org/bugs/?58643
(1) On recent meson versions, it fixes this error:
> extensions/goat-exercises/meson.build:108:0: ERROR: i18n.merge_file keyword argument 'output' was of type array[str] but should have been str
As docs explains, 'output' only accepts one item in i18n.merge_file().
This bug also happens on older meson (but there the reported error is a
lot less useful as it doesn't mention local meson build code).
(2) `setup.isl.xml` is a temporary intermediary file used to create the
Windows installer. It must not be installed.
(3) `gimp30-windows-installer.mo` itself is only used to create
`setup.isl.xml`. It must not be installed as well.
(4) gimp-tips.(its|loc) files (same for gimp-tags ones) should not be
installed. They are only temporary data.
(5) Fix environment variable: s/GETTEXT_DATA_DIRS/GETTEXTDATADIRS/
Fixes:
> /usr/bin/msgfmt: cannot locate ITS rules for ../../../data/tips/gimp-tips.xml.in
(6) Fix various bugs in the *.setup.isl files creation in autotools
build (typo, wrong files used, order of options in `xsltproc`
apparently meaningful, and so on. I guess the autotools build was
not as well tested as the meson one :P).
(7) Fixing the unit test verifying language lists consistency.
(8) `setup.isl.xml.in` must be added to the distribution.
