[Bf-committers] EXPPYTHON sys.executable

[Douglas Bischoff]

Hello:

Sorry this message isn't better targeted, but I'm not sure who can get 
this corrected or point me in the right direction.

The command print(sys.executable) on OS X simply returns "/"

This command should return the path to Blender itself since Blender IS 
the executable for python programs running within itself.

This is useful mostly for programs that want to spawn another "blender" 
such as background renderers.

--- Original Code by Theeth, slight modifications here ---
import os, sys
import Blender

def gui():
  Blender.BGL.glClearColor(0.6, 0.6, 0.6, 0.0)
  Blender.BGL.glClear(Blender.BGL.GL_COLOR_BUFFER_BIT)
  Blender.Draw.Button("ANIM", 1, 10, 10, 80, 20)
  Blender.Draw.Button("FRAME", 2, 100, 10, 80, 20)

def event(evt, mode):
  if evt == Blender.Draw.ESCKEY: Blender.Draw.Exit()

def bevent(evt):
  thefile = "\"" + Blender.Get("filename") + "\""
  if evt == 1:
   print("Anim render starting of " + thefile)
   os.spawnl(os.P_NOWAIT, sys.executable," -b " + thefile, "-a")
  if evt == 2:
   print("Frame render starting of " + thefile)
   os.spawnl(os.P_NOWAIT, sys.executable," -b " + thefile)

Blender.Draw.Register(gui,event,bevent)

Note that the implicit quotes appear to be necessary on my system as 
without them the space in my volume name breaks the path to the source 
file for the render.
