- Require CMake 3.3 for the IN_LIST operator in if() statements
- It looks like Qt 5.12.2 (possibly earlier) supports a QLocale("eo")
so enable Esperanto if that Qt version or later is detected.
- While QObject::tr and gettext give us translations **most** of the
time via the translation mechanism, we sometimes have strings
embedded in configuration files that need to be shown to people
as well. Follow the .desktop style in handling this.
- A key's value **might** be translated; use `key[lang]` for the
translation into one of the languages that Calamares understands.
Code that expects a translated (human-readable) string in a configuration
file can use TranslatedString to collect all the translations of a
given key, so that it displays the right string from the configuration
when needed.
- Using id's as keys in a map orders them indeterminately -- in
practice, alphabetically by key. Switch to a list form so that
the products stick to the order they have in the config file
(which means distro's can list "preferred" versions at top).
- Change to std::chrono::seconds wasn't tried against the (optional)
PythonQt bindings, leading to build failure. Reported by Phil (Manjaro).
FIXES#1210
- Need to create just one QApplication (subclass) with the right
parameters for the UI to work.
- If the UI is enabled and it's a View module, then show the widget
rather than running the jobs.
- The ViewManager needs branding information, which wasn't
initialized -- leading to crashes. Add -b option to give
a specific branding, and default to something take makes
sense when testing modules from the build directory.
- Allows the module to load; doesn't show the UI though.
Package chooser is a **low density** package selector -- unlike
netinstall which offers a high density tree view -- for picking
zero, one, or more items from a small collection of packages.
This can be used, e.g., for "pick exactly one desktop environment",
"pick zero or more text editors" which can then be installed
by another module. The UI is big and shiny (rather than netinstall's
text-based tree view) and isn't suitable for more than a dozen or
so items.
