Readme for cached-io-1.2.0.0

[back to package description]

cached-io: cache a single IO action

Sometimes you have an action that does something really expensive whose results don't change that much. This is a simple library that lets you cache the output of that expensive action for a developer-specified length of time.

test/test-cachedIO.hs shows a very basic usage example.

Developing this library

All standardised tooling is provided by flake.nix.

nix develop

Formatting code

To format use
*.cabal cabal-fmt (cabal-fmt --inplace *.cabal)
*.nix nixpkgs-fmt (nixpkgs-fmt *.nix)

We have not yet chosen a formatter for Haskell source. For now, try to follow the style of surrounding code.
