#! /usr/bin/env python2.6 # # Modulator - Generate skeleton modules. # # The user fills out some forms with information about what the module # should support (methods, objects), names of these things, prefixes to # use for C code, whether the objects should also support access as numbers, # etc etc etc. # When the user presses 'Generate code' we generate a complete skeleton # module in C. # # Alternatively, the selections made can be save to a python sourcefile and # this sourcefile can be passed on the command line (resulting in the same # skeleton C code). # # Jack Jansen, CWI, October 1994. # import sys, os if os.name <> 'mac': sys.path.append(os.path.join(os.environ['HOME'], 'src/python/Tools/modulator')) from Tkinter import * from Tkextra import * from ScrolledListbox import ScrolledListbox import sys import genmodule import string oops = 'oops' IDENTSTARTCHARS = string.letters + '_' IDENTCHARS = string.letters + string.digits + '_' #
