[antlr-interest] case in-sensitive literals

[mzukowski at yci.com]

Try putting "and" in instead.  I think antlr normalizes to lower case.  I
thought this was a bug that was fixed in 2.7.2, is that what you are using?

Subject: [antlr-interest] case in-sensitive literals


I need my literals in grammar to not be case sensitive.
I set the option: caseSensitive=false in lexer, and
caseSensitiveLiterals=false but it still doesn't work.
What I'm trying to accomplish is to have in parser:
andExpr : otherExpr "and" otherExpr
but have it work for either "and" or "AND" or any other combination.
I have more of those literals (or, is, not, etc)
It looks like when I put "AND" in the program, lexer matches Token.ID
Thanks,
Andrew
