Hi Evan, Ah, I really shouldn't code half asleep ;) Fixed it and also done the unit tests. Thanks for the feedback! Balint On 11/28/2011 01:25 AM, Evan Rempel wrote:
Thanks Balint
The patch was not quite complete (don't you hate copy and paste!) as it did not reference your new parser. A small fix, and it worked like a charm.

I have come across some odd lines that really can't be matched/parsed by the patterndb

I would like to match these and parse out the number. The catch is that the number is right justified which means that there is a variable number of spaces before the number.
I am open to suggestions about how to make a paterndb pattern to match this and parse the number into a tag/value pair.
Failing that I would propose that a @SET@ parser.
@SET:name:character set@
This will match a sequence of characters that contain any of, and only those characters listed by "character set"
This will allow matches of arbitrary length separators such as spaces or hyphens or other cases that can not yet be handled.
Comments?
Evan This is something I would have needed recently as well, I ran across the same problem with squid logs and padded usernames. STRING is not okay, since you can only extend the set of matched chars, not specify them and it will match the following tokens as well. I never tried to do a parser before, but it seemed quite easy, so I'm sending a patch in a separate thread that implements your idea and let's see what Bazsi thinks about it.
