Send the full python stack trace to the reporting api,
added BPY_exception_buffer which temporarily overrides sys.stdout and sys.stderr to get the output (uses the io module in py3 StringIO in py2 to avoid writing into a real file), pity the Py/C api has no function to do this.
fix for crash when showing menu's that have no items.
Still not happy with this in the long term but its less problematic then storing the context in pythons namespace which couldn't be set before importing modules.
This might fix a crash quite a few people have reported (but I cant reproduce).
The Python API to define Panels and Operators is based on subclassing,
this makes that system more generic, and based on RNA. Hopefully that
will make it easy to make various parts of Blender more extensible.
* The system simply uses RNA properties and functions and marks them
with REGISTER to make them part of the type registration process.
Additionally, the struct must provide a register/unregister callback
to create/free the PanelType or similar.
* From the python side there were some small changes, mainly that
registration now goes trough bpy.types.register instead of
bpy.ui.addPanel.
* Only Panels have been wrapped this way now. Check rna_ui.c to see
how this code works. There's still some rough edges and possibilities
to make it cleaner, though it works without any manual python code.
* Started some docs here:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/RNATypeRegistration
* Also changed some RNA_property and RNA_struct functions to not
require a PointerRNA anymore, where they were not required (which
is actually the cause of most changed files).
The bug was todo with bpy.data and bpy.types becoming invalid, temporary fix is to re-assign them to the bpy module before running python operators or panels.
will look into a nicer way to get this working.
- Register python panels
- Added a generic class checking function BPY_class_validate() for panels/operators.
- No button drawing yet
Brecht, Added RNA_enum_value_from_id() and RNA_enum_id_from_value() to rna_access.c to do lookups between identifiers and values of EnumPropertyItem's, Not sure if these should go here.
* operator class names
- Changed 'name' to '__label__' (since __name__ is already used for the class name)
- Changed 'properties' to '__props__'
* added a PyObject_GetAttrStringArgs(), utility function which Id like to see in pythons C api.
PyObject_GetAttrStringArgs(pyob, "someattr", "foo", "bar") /* pyob.someattr.foo.bar */
Can draw panels in the scripts space containing RNA and operator buttons.
* Added bpyui.register() so scripts can draw buttons and panels into the scripts space type.
* wrapped drawBlock, drawPanels and matchPanelsView2d
* Operator buttons take a python dictionary used to set the button defaults.
* BPY_getFileAndNum utility function to get the filename and line number python is currently running.
the Python invoke function can then edit the properties based on the event, once its finished the properties are copied back to the operator.
python exec and invoke functions can now return RUNNING_MODAL, CANCELLED, FINISHED, PASS_THROUGH flags
Still need to look into how python operators can make use of invoke/exec for a practical case. (Need to bring back the popup menu's)
