This basically means we talk about localization in the respective
localized variant. e.g. "German (Germany)" ➡ "Deutsch (Deutschland)".
If geoip lookup failed or isn't configured for whatever reason it's a
stretch to expect the user to know english enough to find their own
language. Preferring the localized strings resolves this issue.
Additionally this happens to bypass #712 respectively
https://bugreports.qt.io/browse/QTBUG-34287
as the native names are properly spelled. So, as long as Qt has localized
names the names will also be properly spelled.
- Some locales have no nativeLanguageName(), so instead display
the locale id (e.g. "eo") and the resulting language in English
(which, if it is really unsupported, will be "C").
- The QLocale constructor which takes a string (locale name) doesn't
understand sr@latin, and returns the Cyrillic locale. Fix that
by creating locales ourselves for @latin locales.
- sr and sr@latin now display correctly in the right script in the
native language dropdown.
- The (RTL) text "Arabiy (Misr)" should be entirely RTL, so
make the parenthetical insert -- which would otherwise be LTR
and so mess up the placing of those parenthesis around the country --
explicitly RTL.
- Since there are no RTL languages in Calamares right now with
country-local translations, this isn't visible.
- A locale suggests it is country-specific by having the form <lang>_<country>
- This mostly fixes locale "ar" being presented as "Arabiy (Misr)" when
there is no need to (and the RTL is messed up then, too).
- Introduce intermediate data class for building up the list
of languages to present.
- Sort on the English names, with en_US at the top (ugh).
- Show the native names.
- Much like std::find_if, but slightly muddled because there's
no iterator that we can sensibly use.
- Scan the ComboBox for a locale that matches a predicate.
- Log more as the search for a good locale progresses.
- Don't mix matching the locale with filling the ComboBox
(even though that's slightly more efficient).
- Move widget behavior into its own container / widget class
- Change the RequirementsChecker class to just check the
requirements, returning a results list
- Connect from the module manager to the results widget.
In order to avoid deep copies, Qt containers over which we iterate must be const
The remaining unported cases require qAsConst (Qt 5.7) or std::as_const (C++17)
