So, let's do some rewriting using the pattern matching filter=true mode. Again, the VecMath.g parser will build trees but we'll avoid building an entire tree grammar. We'll focus on some patterns we want to rewrite. Here's the grammar to build trees. …

Can't resist showing off new filter mode for tree grammars (this is working in my dev branch). Imagine I built some trees with Cymbal.g and want to define symbols and push/pop scopes. Previously you had to give full tree grammar even though we'd only have actions in a few spots and don't care about structure (we trust tree builder). By doing tree pattern matching, we get to focus only on those subtrees we care about. …

Thanks to the extraordinary efforts of Jim Idle, we now have ANTLR fully integrated/build with maven. Maven provides an auto-syncing repository so that new release are available within 4 hours of release and makes it easy for people other than me to build ANTLR. If you install the Maven plugin into your IDE (Netbeans/IDEA/Eclipse) then you will find that you can open the directory that contains the ANTLR source code (look for the pom. …

Filter mode for LexersSo, filter mode for Lexers is incredibly useful. For example, I use it for my wiki to HTML translation. you just specify some rules in the lexer with filter=true and it tries all of the rules against the input stream. Precedence is given to rules specified first. In other words, the lexer tries to match the first rule against the current input location. If it fails, it moves to the next rule in tries it. It tries rules until it finds one that matches or it fails. … It's 1.2 with latest ANTLR 3.1.1 Download. Get it while it's hot! http://www.antlr.org/download.html.

I'm working away on the new book. Chock full of useful patterns. (sorry for all the buzzwords in the title/subtitle). We might do a PDF beta in a few months.
