Readme for flow-2.0.0.5
[back to package description]Flow
Write more understandable Haskell.
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.
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 2.2.
Installation
To add Flow as a dependency to your package, add it to your Cabal file.
build-depends: flow ==2.0.*
Usage
Flow is designed to be imported unqualified. It does not export anything that conflicts with the base package.
import Flow

seq x (f x) |
Converting existing code
If you want to uniformly use flow operators you can use HLint with the
hlint-flow.yaml file. For easy use, it is best to extract the
hlint-flow.yaml to your project directory and do
> hlint -h hlint-flow.yaml <source file>
or
> hlint --git -h hlint-flow.yaml
to check all Haskell source tracked by git.
For more information about Flow, please read the Haddock documentation.
