Readme for flow-1.0.7


Write more understandable Haskell.

Version badge Build badge

Flow is a package that provides functions and operators for writing more understandable Haskell. It is an alternative to some common idioms like ($) for function application and (.) for function composition.


Flow requires a Haskell compiler. It is tested with recent versions of GHC, but older or different compilers should be acceptable. For installation with Cabal, Flow requires at least Cabal 1.8.


To add Flow as a dependency to your package, add it to your Cabal file.

build-depends: flow ==1.0.*

See the change log for a detailed list of changes.


Flow is designed to be imported unqualified. It does not export anything that conflicts with the base package.

import Flow
