Single words are hard to translate in context, give some indication what
they do. They're automatically extracted into the pot file.
#. translators: This is a emmoji keyboard layout
#: data/popover.ui:6
msgid "Emoji"
msgstr "…"
#. translators: This is a terminal keyboard layout
#: data/popover.ui:12
msgid "Terminal"
msgstr "…"
This allows them to be translated via po so we don't have to maintain
the translation list by hand or care about empty translation files.
The only downside is that the "overlay layouts" in OVERLAY_NAMES need to
match the ones in the ui file but since a missing one is a clean crash
when selected there's little potential for subtle breackage. We could
even ensure consistency by comparing the two at run time but they change
only slowly this is not much of an issue (compared to how e.g. new
languages can be added now).
Since the current code uses a handcoded approach for popup construction
reuse the unused ui file to keep translatable strings. Since UI file in
popover.rs runs through glib the strings get translated.
Future rework will allow us to get rid of this duplication but since the
ui file went unnoticed for so long who could possibly complain.
Closes: #315
