I'm the author of that stuff (sorry; should have pointed you at the
example on the wiki before).  All the code is in svn!  :)  Please ask if
there's something specific you can't find.


The main grammar,

  http://svn.badgers-in-foil.co.uk/metaas/trunk/src/main/antlr/org/asdt/core/internal/antlr/AS3.g3

the supporting ANTLR implementation classes (including a token stream
with lazyness and a few other bits),

  http://svn.badgers-in-foil.co.uk/metaas/trunk/src/main/java/uk/co/badgersinfoil/metaas/impl/antlr/

the 'helper' classes used by the main grammar to process some of the
island grammars,

  http://svn.badgers-in-foil.co.uk/metaas/trunk/src/main/java/uk/co/badgersinfoil/metaas/impl/parser/

the island grammars themselves,

  http://svn.badgers-in-foil.co.uk/metaas/trunk/src/main/antlr/uk/co/badgersinfoil/metaas/impl/parser/
  ('regex' is broken; don't bother with it)


ta,
dave
