This commit adds:
* A new bpy.app.translations module giving some info about locales/translation stuff (current active locale, all locales currently known by blender, all translation contexts currently defined, etc.).
* The ability for addons to feature translations, using the (un)register functions of above module.
* Also cleans up "translate py string when storing into RNA prop" by removing "PROP_TRANSLATE" string's subtype, and adding a PROP_STRING_PY_TRANSLATE flag instead (this way it is no more exposed to python...).
Addon translations work with py dictionaries: each addon features a dict {lang: {(context, message): translation, ...}, ...}, which is registered when the addon is enabled (and unregistered when disabled).
Then, when a key (context, message) is not found in regular mo catalog, a cache dict for current locale is built from all registered addon translations, and key is searched in it.
Note: currently addons writers have to do all the work by hand, will add something (probably extend "edit translation" addon) to automate messages extraction from addons soon(ish)! To get a look to expected behavior from addons, have a look at render_copy_settings/__init__.py and render_copy_settings/translations.py (rather stupid example currently, but...). Once we have a complete process, I'll also update relevant wiki pages.
This sub-type is actually *only* needed for the "text" property of UI rna api (maybe we should rename it to "PROP_PY_TRANSLATE", as it is anyway only 'active' during conversion from py string to RNA string property...). In fact, I think it should only be used in RNA func properties anyway, as it stores the translated string into the property, it should only be used with "one time" RNA stuff...
User preferences, keymap editor: it allowed to set any event for "key modifier", and not
even to NULL the option. Now it limits to keyboard events, on mouseclicks it clears,
on ESC it exits without changes.
use the same precision for location all over (2-5 was used), use define as 5.
also disallow boolean to have any subtype besides PROP_LAYER_MEMBER, some booleans had TRANSLATION / XYZ subtypes which don't make sense.
Operator descriptions can be NULL pointers,
fix this by making use of PROP_NEVER_NULL flag, when its not set, generated string funcs will test for NULL.
Note about long lines: I did not touch to two pieces of code (because I don’t see any way to keep a nicely formated, compact code, with shorter lines):
* The node types definitions into rna_nodetree_types.h
* The vgroup name functions into rna_particle.c
That was intended change to clear PROP_TRANSLATE flag from bl_label property of
operators, panels and menus (see rev40570)
If this flag leads to another issues it should be fixed in another way.
This fixes#30210: International Font Problem
Python operator subclasses and operator types each get their own SRNA, causing double ups for bpy.types.__dir__()
From the operator type - these share names.
* ot->ext.srna
* ot->srna
Note that this conflict is still there, this only disables 'ot->ext.srna' from being included in dir(bpy.types).
- use NULL rather then 0 for pointers
- use static functions where possible
- add own includes to ensure func's and their declarations don't get out of sync.
