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
