See original attempt at commit 7ec5fd79df65cd3e54d3d14c52df106d71d06c53 This eliminates the need for a resource file at run-time. locale/LanguageNames.txt is intended as a "source file" that is infrequently changed as the set of supported languages changes. The intermediate step, of appropriately copying that file into the C++ source code in src/Languages.cpp, was done by hand. In XCode, I set locale/LanguagesNames.txt and src/Languages.cpp to be interpreted as Western encoding, and then the copy-paste was easy in the editor. The resulting C++ source code file now has string literals that are not 7-bit ASCII.

\brief Determine installed languages.
|
|
|
|
Figure out what translations are installed and return a list
|
|
of language codes (like "es", "fr", or "pt-br") and corresponding
|
|
language names (like "Español", "Français", and "Português").
|
|
We use our own list of translations of language names (i.e.
|
|
"Français" instead of "French") but we fallback on the language
|
|
name in wxWidgets if we don't have it listed.
|
|
|
|
This code is designed to work well with all of the current
|
|
languages, but adapt to any language that wxWidgets supports.
|
|
Other languages will only be supported if they're added to
|
|
the database using wxLocale::AddLanguage.
|
|
|
|
But for the most part, this means that somebody could add a NEW
|
|
translation and have it work immediately.
