[antlr-interest] customize the AST

[Mr Torsten Curdt]

I have the following rule and want to create
a customized AST

instruction!
  : k:LITERAL COLON! v:(LITERAL|QLITERAL) NEWLINE!
  | kk:LITERAL COLON! k1:(LITERAL|QLITERAL) ASSIGN!
v1:(LITERAL|QLITERAL) (SEMICOLON!
k2:(LITERAL|QLITERAL) (ASSIGN!
v2:(LITERAL|QLITERAL))?)* NEWLINE!  
  ;

The first match should become

  instruction --> k --> v

And the second match

  instruction --> kk --> k1 -> v1
                     --> k2 -> v2
                     ...

I had a look into http://www.antlr.org/doc/trees.html
but still don't understand how to do it.

Any help appreciated!

cheers

Torsten
