cwgame: Game information extractor

cwgame is a command-line tool which extracts summary information about each game in the data file. These fields are grouped into two categories. There are 83 fields which are compatible with the Retrosheet BGAME game descriptor tool. These are specified using the -f command-line flag. In addition, cwgame offers a number “extended” fields which expand upon or give more detailed information not easily accessed via the standard fields. These are are specified using the -x command-line flag. Many of these extended fields are defined to match fields which appear in the Retrosheet gamelogs.


cwgame guarantees that the standard field numbers will match those used by BGAME. Standard field numbers therefore can be treated as stable, and it should be safe to write scripts referring to them. Extended fields are provisional, and extended fields may be added or withdrawn in future versions. Extended fields are assigned numbers to maintain a logical cohesion, with related fields being grouped. Therefore, extended field numbers are not promised to be stable. It is recommended to use the field labels instead in writing scripts to process the output of cwgame extended fields.

The following table gives the contents of each of the 84 fields cwgame outputs.
