Haskell Interval ContainersAn implementation of sets of intervals and maps from intervals to values. The intervals may overlap, and the implementation supports efficient queries for all intervals containing a point or intersecting a given interval.
You should normally install it from Hackage with
cabal install IntervalMapI try to keep the interface stable between minor releases, so if you have this as a dependency in a cabal project, use constraints like this:
Build-depends: IntervalMap >= 0.6 < 0.7
