Grammar question...
I have been trying to generate a grammar for a tool I am developing that
has a 'basic-like' syntax. However, I seem to be coming up against a problem in that my syntax should allow
$Sym = 3
as well as
Sym = 3
(that is, there can be an optional dollar sign at the beginning of a line).
The grammar has tokens for symbol names specified as
sym_identifier = letter (letter_or_digit)*;
dollar = dollarsign;
and then listed the dollar token as one of the tokens to be ignored (along with blanks). This seems to work only for
$ Sym = 3 but not for
$Sym = 3
Can someone point out what I did wrong?
Thanks!
Roger
