My Meta Parser
This is fun... I am working now on a task related to ANTLR and its grammar files. Since the grammar file got big and a bit messy, I wrote a small utility to parse the grammar file (.g file) and to sort the parser rules by name. So there it is: a parser of the parser... my meta parser
NOTE: Well, it was not a full-blown parser, but having the parser rules more strictly structured, made it easy enough to implement.
