I have been doing some work with translating C++ code into an equivalent Lisp representation. I eventually want to be able to do some manipulations with the Lisp representation and then regenerate Lisp code. I have been using Berkeley YACC and flex and the grammar written by Jim Roskind. I would like to get around the hack in the lex file presented by Roskind that decides that an identifier is a TYPEDEF based on the 1st character (BTW -- Roskind makes it very clear that the flex file that he provides is just for experimenting and is not meant to be complete). My question is -- Are there any books that I could read to get more information about Berkeley YACC and flex in particular or YACC and lex in general? I am particularly interested in the interface between the two tools. I have considered writing my own lexer in C, but I need more information on the interface to yacc. Thanks for any information. Mick mick@uiuc.edu P.S. If a query of this type belongs in a different newsgroup, please let me know and I will redirect it. I have seen some discussion of the Roskind grammar on this group, so that's why I posted here.
