monadLibWelcome! This is a library written in the programming language Haskell. It can be used by Haskell programmers to quickly construct monads---abstract data types that capture common programming idioms. The library provides a number of building blocks called monad transformers, that can be combined to construct quickly very complicated monads.
- 17 Sep 2007: Version 3.3.0 is now available. It adds an identity transformer (useful as a place-holder) and functions to "derive" basic functions.
- 18 Jan 2007: Version 3.1.0 is now available. It features a new strict identity monad called 'Lift'.
- 02 Jan 2007: Version 3.0.0 is now available. Note that, while similar, it is not a drop-in replacement for Version 2.
- 02 Jan 2007: Happy New Year!
- 12 December 2006: A new major release is coming soon!
- 12 December 2006: To compile monadLib with GHC 6.6 you need to add the flag
-fallow-undecidable-instancesto the cabal file.
- 19 April 2006: Version 2.0.1 released (small changes in Monad.Combinators).
- 12 April 2006: A new look for the web site.
- 19 March 2006: Version 2.0 released.
