Hi!
To generate a custom catch clause in the parser one can write:
@rulecatch {
..code..
}
How do I accomplish the same thing in the lexer?

I have stripped the classical expr.g example and when I run it in
ANTLRWorks it dont work.
The input "(1 + 2) * 3 - 4" (with a newline at the end) just recognizes
"( 1 + 2" and the nothing more.
How come?
grammar Expr;
prog: stat+ ;
stat: expr NEWLINE
| NEWLINE
;
expr
: mul
its a measurement.
ok?

Lets say a three letter word in uppercase can mean one of two tings
like:
10 EUR
where EUR means a monetary unit
10 EUR / TNE
where EUR still means a monetary unit but the three letters TNE now
means a measurement uniot.
How can that be expressed in a grammar??

I want to have one action being executed if no patterns match, like:
stat:
'SWAP' { fh.swap();}
| 'DROP' { fh.drop();}
| { fh.print(text);}
on SWAP fh.swap() gets executed.
on DROP fh.drop()
and if no match i want fh.print() be called with the text that did not match
any
