Python parse_grammar Examples

Example #1

def go (filename, start):
    import meta
    import os
    base, ext = os.path.splitext (name)
    g = meta.parse_grammar (name)
    t = translator (g, start)
    t.gen()
    #pp (t.rules)
    #pp (t.terminals)
    pp (t.lits)
    t.emit_python (base)

Example #2

File: gen_python_parser.py Project: HanWenfang/irken-compiler

def make_parser (path):
    import meta
    import os
    from pprint import pprint as pp
    base, ext = os.path.splitext (path)
    g = meta.parse_grammar (path)
    t = gen_parser.translator (g, lits=lit_map)
    t.gen()
    #pp (t.rules)
    #pp (t.terminals)
    t.emit_python (base)
