Something like that.
Build a dictionary -that will be used as the script global namespace-
containing all the required functions, plus a '__builtins__' entry
(another dict) containing the builtins that you want to provide. For
example, if you don't want to enable "import", don't include __import__.
import __builtin__
builtins = dict(__builtin__.__dict__) # a copy of the standard __builtin__
module namespace
del builtins['__import__']
ns = {
'SETMAP': SETMAP,
'SHOWTEXT': SHOWTEXT,
...
'__builtins__': builtins
}
exec text_of_the_user_script in ns
Warning: this is unsafe!!!. Malicious users could execute arbitrary code;
although this may not be an issue if the game runs on the user's own
system.
The advantage is that you let them use all the power of Python as a
scripting language.
