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.
- use own OrderedDictMini class, pythons collections.OrderedDict is overkill, 179 sloc. replaced with own, 11 lines.
- remove code which stored the class file & line per RNA subclass, this was useful but would raise its own exception every time to generate a stack trace to get the class info so we could use of the class failed to register. the class stores its module & name which can be enough to find where it was defined.
adding meshes in C does:
Add Empty Mesh -> Enter Editmode -> Create Mesh
while python does:
Add Generated Mesh -> Enter Editmode
problem with this is there is no empty undo state for undo-redo to use so it always gave a duplicate mesh on redo-ing.
workaround by adding an empty mesh, do an undo push, and join the generated mesh into the empty one.
this would be fixed if undo stack spanned modes.
would stop the entire menu from drawing if they raised an exception.
now print the exception and continue.
Also added a verbose argument for bpy.utils.(un)register_module() to help test whats being registered.
- 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
This removes auto-registration, committed by Martin r30961.
Realize this is a contentious topic but Brecht and myself both would rather opt-in registration.
TODO:
- addons need updating.
- class list will be modified to use weakrefs (should have been done for existing system too).
- will move bpy.types.(un)register functions into bpy.utils.(un)register_class, currently including these functions in a type list is internally ugly, scripts which loop over types also need to check for these.
- bpy.data.*.load() functions were only accepting UTF-8 paths.
- rna functions/properties now accept byte values rather then strings for file paths.
- bpy.path.resolve_ncase now supports byte objects.
- enabling/disabling no longer prints in the terminal unless in debug mode.
- remove 'header' struct from BLI_storage_types.h, from revision 2 and is not used.
- Add GCC property to guardedalloc to warn if the return value from allocation functions isn't used.
Also added bpy.path.display_name_from_filepath(), since filepaths are not ensured to be utf8.
same as calling: os.path.splitext(os.path.basename(name))[0].encode("utf8", "replace").decode("utf8")
[#25284] Traceback error on "System Info" script
- Align was only working on mesh objects, now operate on all objects, missing boundbox's are treated as single points.
- obj.bound_box was returning all nan's for object types with no boundbox.
- ENUM_FLAG type enums were showing no text when displayed in operator redo panel.
