ANTLR ist ein Tool zum Erstellen von Parsern, die Abkürzung steht für "ANother Tool for Language Recognition". Die dritte, stark überarbeitete Version ist gerade in der Betaphase und kann von http://antlr.org/ heruntergeladen werden. Dieses VIM-Script bietet Syntax Highlighting für die Elemente von ANTLR Parsern und Lexern.
