I have just started using antlr3 and am trying to serialize the AST output of a .g grammar.

As Vladimir pointed out, you can use a a custom AST node class that has serialize capabilities builtin. You could also use a tree adaptor to create the types of nodes you need.
If you only need serialization, and not de-serialization, you could probably just do:
The above will give you a LISP like tree structure. An easy way to do serialization would be to use that in combination with a custom AST node class with an overridden
toString(). SincetoStringTree()uses the node’stoStringTreemethod, it’ll essentially serialize whatever you put intoString. Make its output sufficient and useful and you should be set.
