Which Parser can parse poker-log files, which one is the easiest and best? (Need alternative for Spirit. Gold Parser, ANTLR or ...)

Question

I have to parse some pokerhandhistory-files, log files.

The content is like this:

Theplayername bets $100

All i need is the name, the action(as token) and the amount.

The problem is that the name can also contain an action and spaces.

Example: theplayer bets bets $100

I tried to get it working with GoldParser and ANTLR. Can't get it...

With Boost::spirit there's no problem, it works. The only bad thing is that the compilation time for my whole poker-grammar is awesome, takes 20 minutes.

I saw that ANTLR (C-Api) and GoldParser are a bit better in compilation times.

Would be nice if someone could post a tip on how to grab the information with Goldparser.

Thank you very much!!!!

If you can express the grammar in Spirit, you can write it in AXE (provided you use VC++ 2010). AXE compilation times are an order of magnitude shorter. — Gene Bushuyev, Jul 20 '11 at 19:09
Is there an alternative that works with other compilers and OS? Thank you! — extreme001, Jan 30 '12 at 14:24

They can both be used (ANTLR or Goldparser). But if the format is so simple (USERNAME ACTION ... AMOUNT), then I see no need for a full-blown parser: mind as well process the file line by line and split on white spaces.

Yeah. +1 for suggesting a sane solution. – R. Martinho Fernandes Jul 20 '11 at 15:31
OK. I know that i can do it by simply using RegExes or simple STL with find and so on...but i would like to know how to solve this problem with a parser like Gold or ANTLR. Thank you very much for your answer(s) – extreme001 Jul 20 '11 at 21:46

You could go like this:

Find the last $ sign
Look for the beginning of the "bets " substring that should be before that
The player name is the substring before that position.

No need to get into some complicated parser, do it by hand if the format is just that.

And next thing...there are other formats of this file...like "Playyername: bets $100". The whole content can contain other things as well. So i think it's more comfortable to use a parser. – extreme001 Jul 20 '11 at 21:55
Thanks for your answer! It's really important to do it with a parser. I want to learn GoldParser or ANTLR. And another point...the $-Sign is not always there. I could be another currency or just no currency for playmoney. Please, if someone knows how to do it with GoldParser or ANTLR, please answer! Please no answers with "You don't need a parser" Thanks! – extreme001 Jul 22 '11 at 07:58
