[ragel-users] Anchoring to the EOF

[Julian Morrison]

It certainly does help, thanks.

OK, next, I wasn't able to figure out how to do an error recovery. That is,
when one of the (line*) starts to match, then fails, the error action should
log the error, jump to another regex that matches (any*) :>> '\n', jump back
and pick right back up trying to match more lines. It's plainly obvious that
Ragel can do that, but the wizardry level is a bit above me. Please
elucidate?
