This commit improves the best locale match algorithm by prioritizing
closer matches and add many new tests verifying that this works as
expected.
In order to do this, new information had to be added to the language
database, which was extended with it and updated to use the latest
Unicode CLDR data and latest Windows 11 locale list.
Further, add a set of scripts for maintaining the language database up
to date and a GitHub workflow `genlangdb.yml` which can be run manually
to regenerate the wxWidgets language-related source and header files
from the underlying Windows and Unicode data. It produces 2 artifacts:
- wxLanguageDatabaseDist.zip allows to easily update the
language-related files in the wxWidgets repository by simply copying
all files.
- the normal workflow log and wxLanguageDatabaseLog.zip allow to check
all temporary files of the regeneration process and to detect
potential issues, before the language-related files are actually
replaced by the new ones.
Finally, fix wxUILocaleImplName::GetPreferredUILanguages: Under Windows
10 and above the Windows API function ::GetUserPreferredUILanguages()
returns only the primary UI language plus US English. Additional
preferred UI languages installed by the user are ignored, so instead of
using this function read the list of user preferred languages from the
Windows registry.
Closes#24855.
Including the recently added docs/changes_32.txt one.
This should have been in 304f173924 (Rename the existing changelog to
changes_32.txt and add a new one, 2022-07-11) but was forgotten there.
Import the theme files into a subdirectory without any changes, even not
removing the trailing whitespace, to facilitate updating them in the
future. Do not add the theme as a submodule as it's surprisingly big
(~12MB) and we don't want to spend extra time on cloning it in each of
our CI builds.
Using this theme gives a nicer appearance and supports the often
requested dark mode.
Remove all colour-related options from the existing custom CSS file as
they don't work well in dark mode.
Also switch to using SVGs with transparent background, rather than PNGs,
for the class diagrams, to avoid background colour mismatch in dark
mode.
