name:                concurrency
version:             1.1.2.0
synopsis:            Typeclasses, functions, and data types for concurrency and STM.

description:
  A typeclass abstraction over much of Control.Concurrent (and some
  extras!). If you're looking for a general introduction to Haskell
  concurrency, you should check out the excellent Parallel and
  Concurrent Programming in Haskell, by Simon Marlow. If you are
  already familiar with concurrent Haskell, just change all the
  imports from Control.Concurrent.* to Control.Concurrent.Classy.* and
  fix the type errors.
  .
  A brief list of supported functionality:
  .
  * Threads: the @forkIO*@ and @forkOn*@ functions, although bound
    threads are not supported.
  .
  * Getting and setting capablities.
  .
  * Yielding and delaying.
  .
  * Mutable state: STM, @MVar@, and @IORef@.
  .
  * Atomic compare-and-swap for @IORef@.
  .
  * Exceptions.
  .
  * All of the data structures in Control.Concurrent.* and
    Control.Concurrent.STM.* have typeclass-abstracted equivalents.
  .
  * A reimplementation of the
    <https://hackage.haskell.org/package/async async> package,
    providing a higher-level interface over threads, allowing users to
    conveniently run @MonadConc@ operations asynchronously and wait
    for their results.
  .
  This is quite a rich set of functionality, although it is not
  complete. If there is something else you need, file an issue!
  .
  This used to be part of dejafu, but with the dejafu-0.4.0.0 release,
  it was split out into its own package.
  .
  == Why this and not something else?
  .
  * Why not base: like lifted-base, concurrency uses typeclasses to
    make function types more generic. This automatically eliminates
    calls to `lift` in many cases, resulting in clearer and simpler
    code.
  .
  * Why not lifted-base: fundamentally, lifted-base is still using
    actual threads and actual mutable variables. When using a
    concurrency-specific typeclass, this isn't necessarily the case.
    The dejafu library provides non-IO-based implementations to allow
    testing concurrent programs.
  .
  * Why not IOSpec: IOSpec provides many of the operations this
    library does, however it uses a free monad to do so, which has
    extra allocation overhead. Furthermore, it does not expose enough
    of the internals in order to accurately test real-execution
    semantics, such as relaxed memory.
  .

  details.
