This uses pythons GC so its no overhead during runtime but makes removing ID's slower.
Commented definition 'USE_PYRNA_INVALIDATE_GC' for now, so no functional change.
- bpy.app.driver_namespace, read-only dictionary, edit in-place.
- reset on file load and new file.
- on errors the namespace used to be reset, this should not be needed.
simple example.
def driverFunc(val):
return val * val
bpy.app.driver_namespace['driverFunc'] = driverFunc
... now all drivers can access this function.
Also use const char in many other parts of blenders code.
Currently this gives warnings for setting operator id, label and description since these are an exception and allocated beforehand.
- Also made it so sys.stdin isnt overwritten anymore, instead the interactive consoel overwrites while it executes and restores after.
- removed hope folder from sphinx patch path
- bpy is now a python package, this makes it easier to add utility modules and adjust python startup which was previously using verbose Py/C api. Access should not be any slower since both C and Python modules use dictionary access.
- loop over scripts and load via python (currently F8 reload isnt working, will add back shortly)
- the C module is kept but renamed to _bpy and not meant for direct access from anything but the bpy package.
- bpy_types.py is an exception since it runs before the bpy package is initialized.
Note...
- Python3.1 you don't need to add the .0 for divisions anymore (was esp annoying for button eval)
- Simple dimension input, imperial mi/yd/ft/in, metric km/m/cm/mm, Later could display these values and have a pref for scene scale, atm it assumes 1BU == 1m.
Monthly cleaning round to make it compile warning free.
Mostly it was const stuff (strings, Context), but also
a couple useful fixes, like wrong use of temp pointers.
Only Mathutils callback struct I left alone... design issue.
Mostly harmless ones, except for one about "gzopen64" being
undeclared. This needs some defines in BLI_storage.h to be set
before <unistd.h> is included. Might fix a crash in compressed
file reading, though I'm not sure since it's hard to repeat
the crash consistently.
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.
Now it is possible to write a Python Expression using the variable names for driver targets (see mockup from initial commit) to substitute the appropriate values into the expression.
In the __global__ namespace for PyDriver evaluation, the following modules are available:
* __builtins__ - i.e. the builtin Python functions
* bpy - new Python API
* math or m - math module
For example:
Consider a driver with three targets, named: A, B, C
Now, you could write an expression like:
C if A < 5 else B
or even:
2*C if A < 5 or A > 20 else m.PI*B
Of course, you don't have to have three targets, the above was just an example.
TODO:
* Bring back way to load pydrivers.py
* Blender.Noise equivalent would be nice to have
P.S. I hope I haven't made any terrible Python API coding errors here (i.e. mem leaks, etc.)
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.
this means it caches the compiled pyc files after importing fro the first time.
My times for importing 501 buttons_objects.py files were.
- running each as a script 1.9sec
- importing for the first time 1.8sec
- importing a second time (using pyc files) 0.57sec
Also added "bpy" to sys.modules so it can be imported.
* Added very basic loading of .py files on startup to define panels.
It now executes all .py files in .blender/ui on startup. Right now
this contains the object buttons, the C code for it is commented out.
These files should get embedded in the blender executable as well
eventually, that's a bit more complicated so this works for now.
* For scons and cmake it seems to copy & find the files OK, for make
only "make release" works (same with scripts/ folder it seems).
* Added BLI_gethome_folder function in BLI_util.h. This is adapted
from bpy_gethome, and gives the path to a folder in .blender like
scripts or ui.
There's plenty of things to figure out here about paths, embedding,
caching, user configs ...
- 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.
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.
* Unicode calls in bpy_idprop.c were causing linking errors here. Probably Py-libs for windows would need recompiling with unicode before we can enable this. For now, commented out the offending calls.
"operator.ED_VIEW3D_OT_viewhome(center=1)" calls the operator, converting keyword args to properties.
Need a way to run scripts in the UI for useful testing.
Still need to deal with operator exceptions and verifying args against operator options.
Added temporary WM_operatortype_first() to allow python to return a list if available operators, can replace this with something better later (operator iterator?)
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r12987:17416
Issues:
* GHOST/X11 had conflicting changes. Some code was added in 2.5, which was
later added in trunk also, but reverted partially, specifically revision
16683. I have left out this reversion in the 2.5 branch since I think it is
needed there.
http://projects.blender.org/plugins/scmsvn/viewcvs.php?view=rev&root=bf-blender&revision=16683
* Scons had various conflicting changes, I decided to go with trunk version
for everything except priorities and some library renaming.
* In creator.c, there were various fixes and fixes for fixes related to the -w
-W and -p options. In 2.5 -w and -W is not coded yet, and -p is done
differently. Since this is changed so much, and I don't think those fixes
would be needed in 2.5, I've left them out.
* Also in creator.c: there was code for a python bugfix where the screen was not
initialized when running with -P. The code that initializes the screen there
I had to disable, that can't work in 2.5 anymore but left it commented as a
reminder.
Further I had to disable some new function calls. using src/ and python/, as
was done already in this branch, disabled function calls:
* bpath.c: error reporting
* BME_conversions.c: editmesh conversion functions.
* SHD_dynamic: disabled almost completely, there is no python/.
* KX_PythonInit.cpp and Ketsji/ build files: Mathutils is not there, disabled.
* text.c: clipboard copy call.
* object.c: OB_SUPPORT_MATERIAL.
* DerivedMesh.c and subsurf_ccg, stipple_quarttone.
Still to be done:
* Go over files and functions that were moved to a different location but could
still use changes that were done in trunk.
Patch #9673: "Short patch to make spacehandler event scripts work more like normal python gui script handlers" by Steven Truppe:
http://projects.blender.org/tracker/?func=detail&atid=127&aid=9673&group_id=9
This patch adds the Blender.eventValue variable available for space handlers, holding the event value (aka 1 for button and key presses, X or Y coordinate for mousex / mousey movement). Thanks, Steven. PS: this doesn't break existing scripts.
Bug #17599:
Summary: Python constraints, good in 2.46 not working anymore in 2.47
http://projects.blender.org/tracker/?func=detail&atid=125&aid=17599&group_id=9
Improved my old hack to avoid frame changed scriptlinks from running when rendering stills, should fix this bug. It also causes REDRAW scriptlinks to be executed during renders, but that conforms to how FRAMECHANGED ones work.
BTW: this can still be improved. The current system meant to disable all Python functionality at once needs imo to be replaced by one that allows to enable / disable per feature (scriptlinks, pyconstraints, pynodes, etc.). A better way to inform scriptlinks about what is going on (render, anim, render anim, etc.) would also help. Will discuss with others.
Space types that are to support shortcuts like this should call BPY_menu_do_shortcut(...) from the event queue read method (See winqreadtextspace in drawtext.c for example)
Also scripts will re-run on undo rather then closing.
This is done by saving and loading the name of the script or textblock of the 'Script' datablock, connected to the ScriptSpace. This way when there is a name but the script dosnt run.
Blender runs the script or text block if available.
Submitted by: Thomas Knight (epat)
Parts committed:
1) Fixed a few misspellings in some error strings.
2) Fixed a (theoretical) bug with pyconstraints where a text object could be deleted from python but would remain linked
to the constraint it was assigned to - causing slight UI usage discontinuities!
Not committed yet:
3) Particle system bugfix in this patch has not been committed. Could jahka or brecht check this.
