[antlr-interest] basic question

[gidadoifiok]

I'm very new to antlr (and lexing/parsing).  I wanted
to define a rule for a quote-string.

I tried:

    STRING_LITERAL_SINGLE_QUOTE
	:	'\''! ( ~'\'' )* '\''!
	;

However, I kept getting errors that it did not like the
'.' in the example below:

   'good.stuff'

So I changed the rule to:

    STRING_LITERAL_SINGLE_QUOTE
	:	'\''! ( '.' | ~'\'' )* '\''!
	;

Now it works fine.  Perhaps ~'\' does not include '.'?
I'm trying to get a grasp on all the rules, any help
or pointers to doc is greatly appreciated.

Thanks,
Gidado
