Here's my non-working toy grammar:
grammar test;
tokens {
CAT = 'cat' ;
LP = '(' ;
RP = ')' ;
}
them
: (cat)=> cat
| NAME
;
cat : CAT LP RP ;
NAME : 'a'..'z'+ ;
The lexer insists that "cat" is a CAT instead of a NAME. In the real
grammar, all keywords can also be identifiers. How can this be done?
None of the examples I've seen so far really fit this case.
I tried:
cat : c:CAT {if(!input.LT(1).getText().equals("[")) c.setType(NAME);} LP RP ;
but that doesn't seem to work.
