[antlr-interest] unexpected token: FUNCTIONCALL

[Anthony Youngman]

Solved!

I thought I'd just put in the reference to FUNCTIONCALL, and I actually
needed to put in rather more ... I got misled by the error message.

Cheers,
Wol

Subject: [antlr-interest] unexpected token: FUNCTIONCALL

antlr.Tool is blowing up with this in my treeparser ...

The relevant bit of the parser is

// handle functions etc here ...
// if ident is followed by arglist, change it to function
protected functionorident
	: idnt:IDENT {int junk = st.FindSymbol( 2, idnt.getText());} (
arglist { ## = #(#[FUNCTIONCALL,"function-call"], ##); } )? ;

and the treeparser is

	: (slit:STRING_LITERAL) {st.write("PUSHL "+slit.getText());}
	| (nlit:NUMBER_LITERAL) {st.write("PUSHL "+nlit.getText());}
//	| (idnt:IDENT) {st.write("PUSHV "+idnt.getText());}
	| functionorident
	;

functionorident
	: (idnt:IDENT) {st.write("PUSHV "+idnt.getText());}
	| #(FUNCTIONCALL)
	;

It's the last line - "| #(FUNCTIONCALL)" that it's objecting to. When I
don't have it in, my grammar runs but fails with an "unexpected AST
node" - now I'm trying to tell it about it, it won't compile the grammar
:-(

Cheers,
Wol
