endo-0.2.0.0: endo.cabal

name:                   endo
version:                0.2.0.0
synopsis:               Endomorphism utilities.
description:
  Package defines extra functions for 'Data.Monoid.Endo' data type, and also
  generic endomorphism folding machinery. Generic endomorphism folding can be
  used for various purposes, including as a builder.
  .
  Here is an example how to use it with
  <http://hackage.haskell.org/package/optparse-applicative optparse-applicative>
  package:
  .
  > data Verbosity = Silent | Normal | Verbose | Annoying
  >   deriving (Show)
  .
  > data Config = Config Verbosity FilePath
  >   deriving (Show)
  .
  > options :: Parser Config
  > options = runIdentityT $ runEndo defaultConfig <$> options'
  >   where
  >     options' :: IdentityT Parser (Endo Config)
  >     options' = foldEndo
  >         <*> outputOption     -- :: IdentityT Parser (Maybe (E Config))
  >         <*> verbosityOption  -- :: IdentityT Parser (Maybe (E Config))
  >         <*> annoyingFlag     -- :: IdentityT Parser (E Config)
  >         <*> silentFlag       -- :: IdentityT Parser (E Config)
  >         <*> verboseFlag      -- :: IdentityT Parser (E Config)
  >
  >     defaultConfig :: Config
  >     defaultConfig = Config Normal ""
  .
  > main :: IO ()
  > main = execParser (info options fullDesc) >>= print
  .
  > ghci> :main -o an.out.put --annoying
  > Config Annoying "an.out.put"
  .
  For details how individual option parsers look like see module
  "Data.Monoid.Endo.Fold" which contains other examples as well as this one.

-- Examples require lens and optparse-applicative packages in addition to this
-- packackage's dependencies. When using sandbox it is possible to use "cabal
-- repl" to test examples by using following command:
--
--     cabal repl                                         \
--         --ghc-option="-iexample"                       \
--         --ghc-options="-package lens"                  \
--         --ghc-options="-package optparse-applicative"  \
