More use of bool type, necessitating adding inclusion of BLI_utildefines.h, or moving it up in the inclusion order if it was already included, in various places
- storage.c: make some variables only used in bli_builddir local to that
- storage.c: BLI_file_descriptor_size should allow 0 as a valid file descriptor
- path_util.c: make pointers to non-reentrant storage returned from folder routines const, necessitating making variables holding these returned pointers const elsewhere as well
- path_util.c: BLI_string_to_utf8 closes iconv context in case of conversion error
- blf_lang.c: fill_locales routine now has its own "languages" local variable to construct paths (was stealing internal storage belonging to BLI_get_folder before)
- yes, this does break scripts, but the api is marked experimental.
ED_region_draw_cb_activate() adds a callback to a region type whereas the api made it look like the callback was being added to the region instance.
Use a class method on bpy.types.Space to manage region drawing, eg.
was:
self._handle = context.region.callback_add(draw_callback_px, args, 'POST_PIXEL')
is now:
self._handle = bpy.types.SpaceView3D.draw_handler_add(draw_callback_px, args, 'WINDOW', 'POST_PIXEL')
this report exposed multiple bugs in blender when using a non utf8 compatible home directory.
- bpy.utils.script_paths() would crash when homedir wasn't utf8 (reported bug)
- PyC_DefaultNameSpace() - would raise an error when running when __file__ was non utf8.
- preset filepath property was not set to accept non utf8.
- bpy.paths.display_name would raise an error on non utf8 paths, (used for preset draw)
* Windows installer not working for non-admin users and multiple users
* Addon scripts not installing next to user configuration
* Portable install not being taken into account in all places
The main problem was the windows installer was installing system scripts in
AppData next to the user configuration directory, which is not shared between
users. Now these are installed in ProgramFiles, and only addon scripts added
by the users go to AppData.
On all platforms, addon scripts were sometimes getting installed between
system scripts, because the scripts folder in the executable directory was
given precedence over the user configuration folder, that is no longer done
now. So addons now behave like user configuration, they are preserved even
if you download a newer build of the same blender version.
If you have an installation of 2.57 on windows, the addon install location
will not change until we do the version bump to 2.58, to avoid conflicts with
the existing the installed 2.57 version.
The old behavior of giving precedence to the local folder was done to support
portable install, where all configuration is written to the local folder. This
is now implemented differently: if and only if a "config" folder exists in the
local folder, portable install will be assumed, and files will only be written
to that local folder.
this is not well suited to RNA so this is a native python api.
This uses:
bpy.data.libraries.load(filepath, link=False, relative=False)
however the return value needs to use pythons context manager, this means the library loading is confined to a block of code and python cant leave a half loaded library state.
eg, load a single scene we know the name of:
with bpy.data.libraries.load(filepath) as (data_from, data_to):
data_to.scenes = ["Scene"]
eg, load all scenes:
with bpy.data.libraries.load(filepath) as (data_from, data_to):
data_to.scenes = data_from.scenes
eg, load all objects starting with 'A'
with bpy.data.libraries.load(filepath) as (data_from, data_to):
data_to.objects = [name for name in data_from.objects if name.startswith("A")]
As you can see gives 2 objects like 'bpy.data', but containing lists of strings which can be moved from one into another.
CMake build option WITH_PYTHON_MODULE, will build ./bin/bpy.so
This allows 'bpy' to be imported from python or other applications/IDE's which embed python, eg:
python -c "import bpy ; bpy.ops.render.render(write_still=True)"
This runs in background mode and has similar restrictions to running a script:
blender --background --python test.py
TODO:
- install to site-packages with blender scripts
- add support for imp.reload()
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.
- KeyingSetInfo classes are now collected like Panels, Operators etc so bpy.utils.register_module() can be used.
- move bpy.types.register() to bpy.utils.register_class
