Hello All
It's me again!
As I wrote
<http://www.antlr.org/pipermail/antlr-interest/2010-November/040124.html>,
I'm writing a two-pass grammar. The AST generating code puts some
repeating elements in a list:
> grammar completeOncoPrintSpecAST;
>
> options {output=AST;}
...
> fullDataTypeSpec
> : ':' ( dataTypeSpec )+ ';' -> dataTypeSpec+
> ;
>
...
as per an example on p. 166 of Parr's "... ANTLR Reference" (TDAR):
> /** Collect the result trees from all formalArg invocations
> * and put into an AST list.
> */
> formalArgs : formalArg (',' formalArg)* -> formalArg+
> | ;
How does one walk these repeated elements in a tree grammar? I'm unable
to find any documentation in TDAR or on antlr.org.
Thanks
A
