Module documentation for 0.6.2

Depends on 2 packages(full list with versions):
Used by 2 packages in lts-18.6(full list with versions):

A List monad transformer and a List class. With standard list operations for Lists

Changes

0.6.2

  • ListT‘s Functor instance doesn’t require an underlying Monad.

0.6.1

  • Compatibility with Semigroup/Monoid proposal

0.6.0

  • ListT only available via Control.Monad.ListT. Resolves clash with other packages (for inclusion in Stackage).

0.5.2

  • Alternative instance

0.5.1

  • splitWhenM - a monadic variant of break

0.5.0

  • Add mapMaybe

0.4.4

  • Temporarily remove mapMaybe which will require bumping major version. Its previous addition in version 0.4.3 broke the hexpat package which used open imports causing a name clash when it was added.

0.4.3

  • Add take - a specialized version of genericTake
  • Add splitAtM
  • Add catMaybe
  • Add mapMaybe (temporarily removed in 0.4.4)

0.4.2

  • cons moved to List class so one could override with faster implementations
  • Add enumFrom
  • Add enumFromTo
  • Add tail
  • Add filterL

0.4.1

  • Control.Monad.Trans.List.Funcs: List functions specialized to ListT (to tell type inference what type is used)
  • Avoid using RankNTypes
  • cons is a right-associative operator
  • ListT also available on Control.Monad.Trans.List (reverted in 0.6.0)
  • Add concat (different from join in that inner lists are pure lists)
  • Add concatMap (different from (=<<) in that inner lists are pure lists)
  • Add scanl1
  • Add repeatM

0.4.0

  • Re-introduce joinM due to use-cases in hexpat
  • Add mapL

0.3.0

  • Add minor version number according to the package versioning policy.
  • Use transformers instead of mtl
  • Expose ListT’s data constructor
  • joinM removed. Use (>>= lift) instead. (re-introduced in 0.4.0)
  • Functor instance for ListItem
  • listStateJoin - embeds StateT inside the list.
  • Add takeWhile
  • Add sortOn
  • Add iterateM
  • Add foldl1L

0.2

  • Add instances for Eq, Ord, Read, Show
  • foldrListT' generalized to `foldrL’
  • List class independent of ListT - toListT and fromListT class functions removed.
