Parse C++ header files using ply.lex to generate navigable class tree representing the class structure. CppHeaderParser.py has the advantage of being a pure python C++ header parser. Grap a copy of ply at http://www.dabeaz.com/ply/

...As a guide to what PAS2PHP can achieve... my web site is written in Pascal, and then converted to PHP. (The code is in the source package). PAS2PHP uses the Pascal Parse Tree Classes (PasTree) which comes with FreePascal, and therefore the parsing limits are defined by this library.

Grammar based parsing in Java 8 to a tree structure. Create with no overhead a grammar in java and parse it into a tree structure. Will probably work right away with your grammar.

...Their state machines are precompiled and serialized, so run time initialization is fast no matter how large the rule set. JPlex is not a parser generator; it only generates an interface for its parsers, and it does not build a parse tree. When the lexer identifies a token that has a named event associated with it, it passes the token to the parser method associated with that event. A lexer can dispatch token events to any number of parsers. JPlex is steadily being improved, and the Subversion repo will almost always be newer and better than the binary download.

BlockIt provides a Python framework to scan and parse a program file into constituent nested blocks, however defined, forming a block tree of your code and can be used as a mechanism to "extend" in some sense, the underlying programming language.

The fast, flexible parsing engine. Parse anything in 4 steps: (1) define a grammar, (2) load the grammar into ClearParse, (3) call the engine to parse the source, and (4) traverse the parsing tree. You can even change your grammar at run time.

...A simple BNF style language is used to describe scanner and parser in a UTF-8 source file. The output is described with a template language that is used to add formatting to the parse tree. Code is generated that automatically traverses the parse tree and calls a method on a transformer object to modify the parse tree. Each node is visited in document order, and a method is called at the beginning and end of each node visit. This transformer class is subclassed for customization. SimpleCompiler has many built-in feature for supporting a variety of text based language.
