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()
Annoyance was that operators that defined and __init__ function would need to do...
def __init__(self, another_self):
....
py/rna was calling the class directly with PyObject_Call() but needed to pass the pre-allocated object only so __init__() would run .
This works OK internally but becomes messy since __new__ and __init__ always get the same args there was no way to avoid a superfluous self argument to __init__.

Full description:
When defining an operator button in the UI layout code, trying to set
the value for such an operator's enum properties, where said enum uses
a dynamically generated list of items (which depends on using context
info), will "fail". No context info will be passed to the callbacks
used to generate this list of items, as PROP_ENUM_NO_CONTEXT is still
set on the operator properties (it seems these will only get cleared
when the operator actually runs, which is far too late already for
this usage) so RNA_property_enum_items() will pass NULL instead of a
context pointer *even* when one exists!
I'm not sure of why we even need this flag. It seems to have caused a
few other rounds of problems already, from quick searches I did on
this matter...
- rename rna collection structs Main prefix to BlendData: eg, MainObjects --> BlendDataObjects
- printing python collection now prints its type (when available)
- renamed shadowed vars in bpy_rna.c.
- when making functions static I also made debugging/test functions static, reverse and add definitions to headers instead.
- 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.
- modifier code was using sizeof() without knowing the sizeof the array when clearing the modifier type array.
- use BLI_snprintf rather then sprintf where the size of the string is known.
- particle drawing code kept a reference to stack float values (not a problem at the moment but would crash if accessed later).
- 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
- 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.
- 'axis' arg was not coerced from a tuple like other args now do.
- 'axis' arg was being modified in-place (VERY BAD).
- also made new function matrix_3x3_as_4x4().
- comparing eulers was ignoring the order.
- printing Euler()'s now prints the order too.
- un-orderable types (all except for Vector's), were not raising an exception when compared with >=, >, <, <=.
each accept Euler/Quaternion/Matrix types.
eg:
Euler.rotate(Quaternion(axis, angle))
Vector.rotate(Euler((pi/2, 0, 0)))
matrix.resize_4x4() and euler.make_compatible() were still returning an instance of themselves, now return None.
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.
