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.
- python 3.2 does 'import site' on startup which now tries to parse pyconfig.h which isn't copied. so for now just run without importing 'site', alternative would be to copy the header file for posix systems.
- cache PYTHON_VERSION variable so it can be set to 3.2, needed for copying python installation's other then 3.1.
calling
bpy.ops.wm.read_factory_settings()
... would clear a scripts namespace if running directly, not in a module.
Fix by backing up and restoring the __main__ module.
Also found BKE_reportf wasnt printing all reports in background mode as BKE_report() was doing.
This is an annoying but which isn't a problem for Python because they don't execute multiple scripts, one after another (there is one __main__ and everything else is a module).
So when the __main__ module in sys.modules is overwritten, it decref's the module and clears the dictionary with _PyModule_Clear(), even though the modules dictionary is still in use.
Strangely this problem only happens with Python3.1.1 and Python3.2x svn but not 3.1.2
This commit restores the namespace after _PyModule_Clear() sets all its values to None.
from mathutils.geometry import PolyFill
I couldn't find a way for python's inittab to do this so just inserting mathutils.geometry into sys.modules manually.
having the blend file as a part of the __file__ variable is not essential, this is fixed in python 3.2 so add an ifdef and don't use the blend file path for py older then 3.2.
applied to python api and exotic.c, removed some args being passed down which were not needed.
keyword args for new mathutils types were being ignored when they should raise an error.
now addon path is created using the same path functions and selecting where to save the startup.blend
also made some minor changes to path handling funcs.
* Fix var declaration in bpy_interface.c
* Remove forward declarations from py_capi_utils.h: they are unnecessary and break compiles (there were probably many warnings about this during compile with GCC).
The BGE was getting the namespace dict directly from __main__ which conflicts
with my recent fix to get the pickle module working which to overwrote the __main__ module on script execution.
Simple fix is to have the BGE and Blender use the same method of getting namespaces.
Renamed CreateGlobalDictionary() to bpy_namespace_dict_new() and moved into bpy_internal_import.c
pickle still wont work in the BGE since we make a copy of __main__ namespace but for speed would rather not have to replace the __main__ module many times per second.
- fix for reload (f8) crashing, missing incref when creating the script namespace.
- store the module names rather then the modules for reloading incase the modules get out of date.
- removed the immediate option from C/api and now store in python only, when python loads modules it sets it to False.
- unloading a module would clear the entire TypeMap for all modules, only remove the module types that is being unloaded.
- added some checks for bad class registering, report errors rather then crashing.
recent commit cleared the __main__ namespace once a script finished which meant classes defined there would loose their namespace.
now inset a new __main__ module into sys.modules for every script that runs, any classes that are registered will hold a reference to that modules namespace.
- the __main__ modules namespace was initialized cleanly but left dirty, now restore when finished executing a script incase a module uses this later.
- made the interactive console use the __main__ modules namespace.
- __import__("__main__").__dict__ will now always match the current scripts namespace. (which is what pickle expects).
- __builtins__ as a module rather then a dict from PyEval_GetBuiltins() acts slightly differently, use the module to follow python.
for some reason mbstowcs() was converting '/home/matrem/Téléchargements/' to '/home/matrem/T', where blenders utf8towchar() worked correctly, tried changing my locale but didnt help so using blenders utf8towchar() function.
- python change, dont import 'bpy' by default, initially I thaught this would make scripting easier but it ends up being annoying when you want to register a script or if you want to import it. (more trouble then its worth to save 1 line, also not very pythonic).
