When generating lexers/parser on the command line, you'd do something like
this:
java -cp .:antlr-3.2.jar org.antlr.Tool /path/to/your/grammar.g
(the Tool class has a static main method taking a command line parameter!)
So generating them in your own code would look like:
String yourGrammarFile = "/path/to/your/grammar.g";
org.antlr.Tool.main(new String[]{yourGrammarFile});
Kind regards,
Bart.
