ANTLR 3.5.3 · org.antlr.tool.RandomPhrase

Generate a random phrase given a grammar. Usage: java org.antlr.tool.RandomPhrase grammarFile.g startRule [seed] For example: java org.antlr.tool.RandomPhrase simple.g program 342 The seed acts like a unique identifier so you can get the same random phrase back during unit testing, for example. If you do not specify a seed then the current time in milliseconds is used guaranteeing that you'll never see that seed again. NOTE: this does not work well for large grammars...it tends to recurse too much and build really long strings. I need throttle control; later.
