Dear ANTLR experts,
I am new to ANTLR, just started studying it. Could you please provide
me some ANTLR tutorial links? I got few. But those are not providing
a detailed explanation. I am in need of a good tutorial for parse
tree generation in ANTLR.
I am going through Michael Schmitt's SDL Parser 2000, which was
written in ANTLR. With my very little knowledge in ANTLR, I
understood your SDLLexer.g. But I have some doubts in SDLParser.g.
Could you please provide your valuable clarifications on the same?
1. What does ##, #([SDLspecification], ##) indicates
in the statement
{ ## = #([SDLspecification], ##); }
?? ?????????????? ??
2. Why two rule names are given for the same rule?
ScopeUnitKind!:
start01: PACKAGE! { ## = #[Package];
SETLINECOLUMN(##, start01); }
Why ScopeUnitKind is followed by !?
3. What is the use of nameDef[Type] rule? It has
been commented out internally.
Awaiting your valuable response...
Kind Regards
Elango
