[Bf-python] blender and external editors - workflow?

[Dietrich Bollmann]

Cheers, Dietrich


PS:

I am using it from an external lisp program for the automatic generation
of shapes and together with emacs and emacs' python mode adapted to
blender, as I prefer emacs for editing code to any other editor.  The
python mode was assembled for my private use and - even if it works just
fine for me - it is very experimental:
