[antlr-interest] Re: strange bug (v 2.7.2)

[Lloyd Dupont]

from memory in some sample code I found they have a rule like that

token {
    NOT_EQ; LessT; LE;
}

NOT_EQ: '<'
    ( LA(2) '=' { _ttype = LessT} | ....to be continued ..)

I can't remember better, sorry, I haven't write any ANTLR code since a
while.
Anyway it seems silly to me, this should suffice, isn't it ?
options { k= 2; }
NOT_EQ = "<>" | "!=" ;
LessT = "<=";

or something that simple....
why should I have to check it myself .....

ok, let you know .......

anyway all my stuff has to wait until friday (vacation tomorrow)...
CU
