Good trick. However, it pollutes the namespace of class Commands. Take a
look at the tree::
@file leoCommands.py-->class Commands-->
c.Birth & death-->c.__init__ & helpers
You will see that there is a significant chance of a collision with
essential ivars of the Commands class.
Your scripts can avoid this pollution as follows (Tested code)::
def MyFunction(s):
g.es(s)
d = g.app.permanentScriptDict
key = 'temp functions'
d2 = d.get(key,{})
d2['myFunction'] = MyFunction
# Later...
f = d2.get('myFunction')
f('This works')
Not as clean as your solution, but *much* safer. If you do use the unsafe
way, I suggest starting all "injected" functions with a common prefix, like
perez. I always append 'leo_' to any ivars injected into Qt classes. Or
just use c.k.registerCommand ;-)
