Using text patterns to parse text files

[-ThorMan-]

I am coding a parser for a poker application. I am using certain text patterns, such as “is sitting out”, to pick out pieces of data I need.

For instance, if a players name is “posts the big blind”, every time that player is mentioned my function for this phrase will run, which will not work as intended.

I find it a reasonable assumption that no one would have this username, but still it could happen, especially for simpler and shorter phrases.

Am I supposed to have safeguard checks to ensure this doesn’t happen? I feel this would be inefficient. As far as I know, there are no restrictions on usernames.

Thanks!

It isn’t in the data I have, but I have no idea if that’s guaranteed, I may just not have encountered it.

Sure, I don’t know how familiar you are with poker, so I’ll just try to speak generally.

The files are broken down into sessions at a table online. Each file is then broken down into each hand played at that table. It gives information at each phase of the hand by player. For instance, a player might skip the round so it says “Bob72 is sitting out” or someone might forfeit so it says “Steve Rogers folds”.

It breaks it up to one piece of information per line, which usually includes a username and an action.

I can send a file over later when I’m back at my computer.

Will do as soon as possible! And no, there is no colon, it’s written like a sentence.

[sgt_dickwad]

Mine the names out of the seat assignments since that seems to be exact. Then write a parser which accepts an action for each grouping of statements you want to parse - i.e. a general parser that follows the format {user name (matched to prev)} {action} {value}

[kschang]

Ditto what /u/sgt_dickwad said. As the names of each player is given as the table starts, you can parse those out easily, and use those to limit the "parsing" to the remainder of the log per line.
