Batch run

The program runs all scripts in the object and simulation folders. The main purpose is to verify that all scripts run correctly, or at least that they can be executed without causing errors.

Most scripts do not run in earlier versions of Blender. To ensure that we are not stuck with an outdated Blender, we first check the current Blender version, which is available as bpy.app.version.

if bpy.app.version < version:
    msg = 'Blender too old: %s < %s' % (bpy.app.version, version)
    raise NameError(msg)

# Delete all old objects, so we start with a clean slate.
scn = bpy.context.scene
for ob in scn.objects:
    scn.objects.active = ob
    print("Delete", ob, bpy.context.object)
    bpy.ops.object.mode_set(mode='OBJECT')
    scn.objects.unlink(ob)
    del ob

# Path to the code. You must change this unless you place the
# snippets folder in your home directory
scripts = os.path.expanduser('~/snippets/scripts/')
