- point to main Calamares site in the 'part of' headers instead
of to github (this is the "this file is part of Calamares"
opening line for most files).
- remove boilerplate from all source files, CMake modules and completions,
this is the 3-paragraph summary of the GPL-3.0-or-later, which has
a meaning entirely covered by the SPDX tag.
- the `parent` when installing a translator was not used, so drop it
from the API. Chase some uses of the API, but leave welcome-modules
broken: there's a merge of those coming.
- To support translation testing, without needing to recompile
Calamares, load files from the local directory when debugging,
or from /usr/share/calamares/lang/ in general.
- This allows updating translations and testing them with just
lrelease (a translation build tool) installed, without rebuilding
Calamares.
- This allows distro's to ship updated or modified translations without
rebuilding Calamares.
- Split the actual loading of translations into classes
to encapsulate the loading logic,
- Build a collection of classes to do the different kinds
of translation loading,
- Build a generic function to load something and update a
static pointer to the translation.
This makes installTranslator() much easier to read, and encapsulates
the type-specific loading somewhere else. While here, add a timezone-
translations loader so that the split-out TZ translations also work.
- sometimes a slot is easier than a lambda. Introduce
a macro CALAMARES_RETRANSLATE_SLOT that calls a given
slot in an object on language change.
- extend the retranslator with support for calling slots:
- use Qt's signal/slot mechanism alongside the private
list of functions to call
- provide convenience for obtaining the retranslator of
an object.
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)
