Hello! Plyplus is finally stable enough to announce.
Plyplus is a general-purpose parser built on top of PLY, written in python, with a slightly different approach to parsing.
Most parsers work by calling a function for each rule they identify, which processes the data and returns to the parser. Plyplus parses the entire file into a parse-tree, letting you search and process it using visitors and pattern-matching.
Plyplus makes two uncommon separations: of code from grammar, and of processing from parsing. The result of this approach is (hopefully) a cleaner design, more powerful grammar processing, and a parser which is easier to write and to understand.
Plyplus also provides advanced analysis tools for querying and transforming the AST.
