Red Bear OS is a full fork. All sources must be available from git clone with zero network access. Removed gitignore rules that excluded fetched source trees under recipes/*/source/, local/recipes/kde/*/source/, local/recipes/qt/*/source/, and vendor source trees. Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded. 127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt frameworks, mesa, wayland, DRM drivers, and every other recipe source.

/* KDE 4 format strings are processed by method
|
|
KLocalizedStringPrivate::substituteSimple(string,'%',false) in
|
|
kde4libs-3.93.0.orig/kdecore/localization/klocalizedstring.cpp .
|
|
A directive
|
|
- starts with '%',
|
|
- is followed by a non-zero digit and optionally more digits. All
|
|
the following digits are eaten up.
|
|
An unterminated directive ('%' not followed by a digit or at the end) is
|
|
not an error.
|
|
%1 denotes the first argument, %2 the second argument, etc.
|
|
The set of used argument numbers must be of the form {1,...,n} or
|
|
{1,...,n} \ {m}: one of the supplied arguments may be ignored by the
|
|
format string. This allows the processing of singular forms (msgstr[0]).
|
|
Which argument may be skipped, depends on the argument types at runtime;
|
|
since xgettext cannot extract this info, it is considered unknown here. */
