libtour

libtour is a generic tournament processing library written in C . Rules, teams and schedule of a tournament are defined in the Scheme programming language (Guile) and given to the library as input.

Features:

- simple protocol to communicate with the library through request/reply objects
- queries of data coming from the Scheme definitions (game, team and team result fields, date format etc)
- queries of interpreted data (table of standings, game schedule with results, teams etc)
- notion of the "local team ID" that allows definitions of future stages without knowing real teams
- ability to query the information for stages whose teams hasn't been determined yet
- support for different group formulas (round robin, game count, playoffs)
- support for excessive games (those in the schedule but not necessary to play, like in a playoff stage)
- support for carry-forward game results, and incidentally, predefined games results
- game schedule verification
- support for dynamic creation of (parts of) the game schedule
- support for sorting conflicts within a group (when the rules fail to determine exact team positioning) and providing manual resolution for such conflicts
- summary groups (one per stage) provided by the library
- support for creating custom groups on the fly using team and/or game filtering procedures defined in Scheme; information on the interface of available filters
- loading and interpreting more than one tournament at a time
- saving and restoring tournament state
