Hi,
I have started using antlr to catch up my lack of knowledge in
parsers. This is a great product, thanks a lot !
I am trying to create my own DSL, and started very simply with parsing
the following
name: foo;
But got a problem while using antlworks. I get space-related problem:
name:foo; -> works
name: foo; -> antlrworks gives me an error (mismatchedTokenExpression exception)
But if I use the generated parser from antlworks, both expressions
with and without spaces are correctly parsed.
The grammar boils down to:
grammar T;
program : statement+;
statement
: metadata;
metadata
: 'name:' WORD ENDSTMT;
WORD: 'a'..'z'+ ;
WS: (' ' | '\n' | '\r' )+ {$channel=HIDDEN};
ENDSTMT : ';';
I use python for the generated parser, if that matters,
thank you,
David
