示例1: parse
# 需要导入模块: import lex [as 别名]
# 或者: from lex import lexer [as 别名]
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:
return self.parseopt(input,lexer,debug,tracking,tokenfunc)
else:
return self.parseopt_notrack(input,lexer,debug,tracking,tokenfunc)
# !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
# parsedebug().

# 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:

# #--! DEBUG
# statements
# #--! DEBUG
