[Bf-committers] [Bf-blender-cvs] SVN commit: /data/svn/bf-blender [28819] trunk/blender/release/scripts/ modules/bpy_types.py: text utility functions.

[Campbell Barton]

Id rather have all RNA objects act the same and have a predictable str(obj)
Without meaning to you could end up spewing pages of text into the console.
for text in bpy.data.texts:
    print("%s blah blah" % text)

a text in blender is more similar to a file then a string so I'd
rather have python implement functions over Text which make it act
like a file object.
text.read()/seek()/tell()/readlines()/write() etc..

This way you could do
 sys.stdout = bpy.data.texts["output"]

This should remove the need for as_string/from_string but also needs
more time to check functions work as expected.
