[Pythonmac-SIG] Spotlight and Python

[Jonathan Wight]

I looked at parser but discounted it too soon. After a bit of playing  
I managed to get the following code to provide lists of class names  
and function names.

Thanks Bob!

     Jon.

#!/usr/bin/python

import parser
import symbol

def find(inTuple, inSymbol):
     theClasses = []
     if inTuple[0] == inSymbol:
         print 'FOUND'
         theClasses += [ inTuple[2][1] ]
     for theItem in inTuple[1:]:
         if type(theItem) == type(()):
             theClasses += find(theItem, inSymbol)
     return theClasses

theSource = open('/Users/schwa/Desktop/Test.py').read()
ast = parser.suite(theSource)
tup = ast.totuple()

print find(tup, symbol.classdef)
print find(tup, symbol.funcdef)
