示例1: parse

# 或者: from lex import lexer [as 別名]
def parse(self,input=None,lexer=None,debug=0,tracking=0,tokenfunc=None):
if debug or yaccdevel:
if isinstance(debug,int):
debug = PlyLogger(sys.stderr)
return self.parsedebug(input,lexer,debug,tracking,tokenfunc)
elif tracking:

# This is the debugging enabled version of parse(). All changes made to the
# parsing engine should be made here. For the non-debugging version,
# copy this code to a method parseopt() and delete all of the sections
# enclosed in:

# statements
# #--! DEBUG
