pyParsing is a parsing toolkit which can parse strings of LL(1) grammars. This library is for learning purpose only, for efficient and convenient parsing techniques have a look at ply, a pure python implementation of lex and yacc. Though the parser is fully functional (includes a tokenizer), there is much work to be done in terms of usability. Look at the documentation in /doc (to be written) for more information on this module. ######################## To Do ########################### # add auto elemination of left recursion, auto left factoring of the grammars # error recovery techniques # add attribute passing mechanisims # better way of eading user input. current way of taking the grammar specs from the user is too clunky and error prone. Have to make this better # A graphical animation support, to visualize the parsing. since this library is mainly for learning purpose, this would be great!! ###########################################################
