funcparserlib Description

Recursive descent parser library based on functional combinators Parser combinators are just higher-order functions that take parsers as their arguments and return them as result values. Parser combinators are:* First-class values* Extremely composable* Tend to make the code quite compact* Resemble the readable notation of xBNF grammarsThe parsers made with funcparserlib are pure-Python LL(*) parsers. It means that it's very easy to write them without thinking about look-aheads and all that hardcore parsing stuff. But the recursive descent parsing is a rather slow method compared to LL(k) or LR(k) algorithms.So the primary domain for the funcparserlib library is parsing little languages or external DSLs (domain specific languages). Requirements: · Python What's New in This Release: · Fixed bug in results of skip + skip parsers · Added FAQ question about infinite loops in parsers · Debug rule tracing can be enabled again
