PLY (Python Lex-Yacc) : ウィキペディア英語版 | PLY (Python Lex-Yacc)
PLY is a parsing tool written purely in Python. It is basically a re-implementation of Lex and Yacc originally in C-language. It was written by David Beazley. Unlike Lex and Yacc in C which uses LALR parsing technique, PLY uses LR parsing which can incorporate large grammars easily. PLY also has extensive debugging and error reporting facilities. ==History== David Beazley originally wrote PLY in 2001 for an introductory course on compilers. He created it to aid the students in creating compilers for simple Pascal-like languages.〔http://www.drdobbs.com/web-development/prototyping-interpreters-using-python-le/184405580〕 Since then it has seen many improvements and has come out as one of the popular parsing tools.
