Flow

Write more understandable Haskell.

---

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

Requirements

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.

Installation

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

build-depends: flow ==1.0.*

For other use cases, install it with Cabal.

$ cabal install 'flow ==1.0.*'

Flow uses Semantic Versioning. See the change log for a detailed list of changes.

Usage

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

import Flow

Here is a quick overview of the functions and operators that Flow provides.

Flow	Base
apply x f	f x
`x	> f`
`f <	x`
compose f g x	g (f x)
f .> g	f >>> g
g <. f	g . f
apply' x f	seq x (f x)
x !> f	-
f <! x	f $! x
