-- Stephane Soppera (thanks) reported libc stat function fails for paths ending with "\" under win with free VC++ compiler toolkit 2003:
removed final '/' (BLI_make_file_string changes the '/' to '\\\\' for win) slashes from relevant paths, that should take care of it . Note: here (linux, glibc, gcc 3.3.3) stat doesn't have this problem. Also checking if U.pythondir ends with a slash and, if so (as long as its length > 2 to), removing the slash, for the same reason.
-- small cosmetic changes in BPY_menus.c for debug msgs and in header_scripts (added a separator in the Scripts win -> Scripts menu).
- moved bpydata/ to scripts/bpydata/ and added a config/ subdir to it;
- created scripts/bpymodules for py modules (also got rid of those "mod_"'s appended to the files);
- updated scripts accordingly.
This will require you to "reinstall" (just copy the scripts/ dir over your older one) if you have a .blender/scripts/ dir somewhere. Otherwise some scripts won't work. You can use the updated "Help->System->System Information" script here to check all is fine. An installer script yet to be written will help users with these issues, specially to make the user defined dir have the same structure expected from the default scripts dir, so the basic facilities (module search; saved config data; scripts: installer, help browser, config editor) are also available for a user's own collection of written and downloaded scripts.
BPython:
- slikdigit's crash was because he had no <home or blender exe location>/.blender/:
proper check added and also now if all else fails the <cvsblender>/release/scripts/ dir is also searched for scripts. All this registration dirs stuff is a little messy (installation!), so please report any troubles (I only tested on linux).
- slight change in error report in BPY_interface.c's BPY_menu_do_python; remembering to set globaldict pointer to NULL there, too.
- moved bpy_gethome() to EXPP_interface.[ch]
- "//" as user defined python dir is ignored while looking for scripts, considering it's only a default some users use, not really meant for a scripts dir.
NOTE: BLI_winstuff.h was meant to be a wrapper around windows.h to handle
undefining various crap that windows.h defines. Platform specific headers
should only have to be included in a few places. This reduces the number
of inclusions of BLI_winstuff.h to 16 which is a much more reasonable
number (than the 144 or whatever it used to be)
- removed reference in render.h (really bad, shouldn't include a platform
specific header so widely unless really necessary)
- added M_PI, M_PI_2, M_SQRT, M_SQRT_2 defines to BLI_arithb.h... this is
a better place as it is more the "standard" blender math header. left
in winstuff.h as well for the moment for simplicity
- other changes are patches to code so everything works ok with this
shuffling.
- Added Blender.Run(script) + doc update (forgot to mention in my previous commit).
Trying to fix two mistakes from my previous commit:
- nmesh.transform(): forgot yesterday that affine vectors have 4th component = 0, now updated normals transformation accordingly.
- As Ton pointed, recursive parsing of scripts dirs in search of scripts was a mess. I simply forgot about the "//" trick and much worse, to protect against worst cases ("/", for example). Now the code uses BLI_convertstringcode to take care of "//", doesn't process if dir = "/" and there are limits:
max depth for traversing subdirs = 4
max dirs in the tree = 30.
I'll work more on this, check more, but these changes were tested and should make the code safer, of course, so I'm committing. Sorry about the mess, I should take lessons on defensive programming ...
- Scripts:
fixed error in "Save Current Theme" which prevented it from automatically updating script registration in menus.
cosmetic changes in a couple of Campbell's sel_same.py script strings + more descriptive name for its new menu place (3d view, face mode -> select menu).
small updates to help_browser.py script.
The above changes are related to this:
- Added new script menu entries: Render (for exporters to renderers), Themes, FaceSelect (this already at the proper place). Updated Scripts win->Scripts menu so it won't show all available entries, only the ones we mean to see there.
- Updated menu registration so that scripts folders can become trees. The release/scripts/ dir should be updated soon with subdirs like converters/, modifiers/, generators/ or whatever -- better discuss first (or is it? /me afraid of long irc discussions during meetings :) ).
- Modules:
Blender: added 'udatadir' option to .Get() function and added var Blender.mode to tell if Blender is in bg or interactive mode.
NMesh: added Campbell's nmesh.transform(matrix, recalc_normals = False) method (reworked, so my fault if it doesn't work).
- Bugs fixed:
#2123: http://projects.blender.org/tracker/?func=detail&atid=125&aid=2123&group_id=9
Reported by Ken Hughes (thanks!), who also found the exact problem later (it was in Text.Load, not with script links -- if only I had checked emails these days ... lost > 1 hour today to find the problem: passed filename to M_Text_Load was later being written over by a function called by add_text). Also saw that Text.Load wasn't checking existence of passed filename (duh!), now it does.
#1655: http://projects.blender.org/tracker/?func=detail&atid=125&aid=1655&group_id=9
Reported by Chris Want (thanks!): command line "blender -P script" not working properly for bg mode ("blender -b blendfile -P script").
Had to make some small updates to get it working (bg mode for scripts was never explicitely handled, it worked due to collateral effects, let's say), interested readers can check the report after I update it or the API_intro.py doc file. After more testing we can make further updates. Updated many places to not call redraws if in bg mode, now it is officially available. Blender outputs its own info when rendering in bg mode, if that is considered a nuissance we'll have to add a few "if (during_script())" calls outside bpython.
- Removed a few warnings here and there and also updated docs.
-includes:
*Text3d accessors - ablity to manipulate FONT objects through python
*update to Object.link - calls text_to_curve upon ob_font link for drawing
*update to constant.h - constant type checking define
*update to curve.c - clamp values on getters/setters
*clean up of Text3d module
- Gert de Roost reported an inconsistency between nmesh.getMode and .setMode. Now .setMode() optionally accepts an int value, as returned by getMode().
- Campbell Barton pointed that object.getData(name_only=True) was by mistake returning the obj name, not the obdata name, as it should. Fixed now.
- small doc updates
Thanks both for the reports.
-- Ton caught a redraw trying to free a busy slider button in a script. Made sure the redraws don't happen in the scripts win during slider updates, but the realtime slider (automatically updates the 3d view) isn't working yet as it probably shouldn't with the current code. There's a pre 2.25 comment in Draw.c about it being hackish and wrong;
-- Melchior FRANZ reported a bug related to a script dict being freed too early (when two instances of the same script were on: one with a gui and the other with a file selector -- selecting the file triggered the problem);
-- bug #2074 reported by Roland Hess: totally empty string button -- no prepended but->str (e.g. "OB:") neither but->poin (the actual string) -- crashing Blender. Crash happened on editscreen.c: screen_delayed_push_undo calls strncpy() without checking the passed string. Didn't mess with it, better let the coder in charge of undo (Ton, right?) choose a preferred way to deal with it (report error, simply use blank string). Staying on the python side at least for now, I just made but->str = " " (a space) when user doesn't define it, so the crash shouldn't happen anymore.

Thanks guys for reporting the problems.
- applied Campbell Barton's patch for access to Oops location and selection of materials, mesh data and objects, slightly modified. Thanks, Campbell;
- got rid of warnings in many files, hopefully not introducing any other during the process. Mostly this was done: 1) new EXPP_incr_ret_True/False functions were added and used instead of "Py_INCREF(Py_True/False); return Py_True/False;". Currently at least the functions use the fact that PyTrue/False == 1/0 and use 1 and 0 to avoid the warnings. 2) Filling of certain types structs got 0's added for all not defined data and methods. This is surely Python version specific, since these structs can change size and content at each major version number Python update.
- NMesh: made nmesh.update accept an optional 'vertex_shade' param to init vcols with shading info, like when you enter vpaint mode or press the relevant "make" button for a mesh without vcols. This is still a test, the functionality was requested by Manuel Bastioni for the SSS script they are working on:
http://www.dedalo-3d.com/index.php?filename=SXCOL/makehuman/articles/subsurface_scattering_in_python.html
- sys: made makename() accept files with max FILE_MAXDIR+FILE_MAXFILE name length, should fix#2192. Was only FILE_MAXFILE, a mistake;
- Image: added .setFilename(), contributed by Campbell Barton;
- Camera: added camera.get/setScale for the new param added by Ton for ortho cameras. Requested by Jean-Michel Soler for the Texture Baker script;
- related doc updates.
- NMesh: added face.sel and face.hide attributes to NMFaces, to set / get selection and visibility state of faces as they appear in edit mode.
- doc updates, including the right fix to two edge related methods, thanks to Stephane Soppera for pointing it (my fault, Stephane).
- Fix related to bug #2157: crash in Blender.Image.image.reload() method. "G.sima" was not being checked for validity. Fix by Joilnen B. Leite (pidhash). Thanks!
http://projects.blender.org/tracker/?func=detail&atid=125&aid=2157&group_id=9
- Added optional argument to Blender.Object.object.getData() method: getData(only_name = True) or (only_name = 1) or (1) will return only the obdata name, not a wrapper for the given struct. This is a test based on a request by Campbell Barton who submitted code for his proposed .getDataName() method (thanks!).
- doc updates and small fixes.
- Stephane Soppera added long missed support for edge data in Blender.NMesh + related doc;
- Michael Reimpell improved script registration (fixes bug report #2160) and the file and image selectors in Blender.Window (improved with suggestions from Yann Vernier). They now suppport methods as callbacks;
- World.get/setMode were not registered, so could not be directly called (reported by Ken Hughes). Still needs some work to improve things, including docs.
Scripts:
- Jean-Michel Soler updated his texture baker based on input from Appolux;
- Campbell and Jean-Michel improved the bvh importer: faster, better float units scaling (by Campbell); supports Poser 3.01 files (by jms).
Thanks guys!
- Added Blender.UpdateMenus() + doc: so scripts can automatically update Blender menus when they create (or download or whatever) new scripts to be registered.
- Removed a long deprecated function from the Blender module (release dict).
Matt (broken) mentioned the UpdateMenus function a couple weeks ago. I also updated the Save Current Theme script to use it. This is all related to his ideas to use scripts to save and restore themes and e.g. render presets.
- patch by Jonathan Merritt: new function Blender.Draw.Image() + its doc;
- patch by Campbell Barton: .users attribute for many types;
- tiny internal change in nmesh.hasVertexUV() method.
Thanks to Jonathan and Campbell for the patches and the patience!
