  "github_readme_excerpt": "# ghcid [![Hackage version](https://img.shields.io/hackage/v/ghcid.svg?label=Hackage)](https://hackage.haskell.org/package/ghcid) [![Stackage version](https://www.stackage.org/package/ghcid/badge/nightly?label=Stackage)](https://www.stackage.org/package/ghcid) [![Build status](https://img.shields.io/github/actions/workflow/status/ndmitchell/ghcid/ci.yml?branch=master)](https://github.com/ndmitchell/ghcid/actions)\n\nEither \"GHCi as a daemon\" or \"GHC + a bit of an IDE\". To a first approximation, it opens `ghci` and runs `:reload` whenever your source code changes, formatting the output to fit a fixed height console. Unlike other Haskell development tools, `ghcid` is intended to be _incredibly simple_. In particular, it doesn\u0027t integrate with any editors, doesn\u0027t provide access to the `ghci` it starts, doesn\u0027t depend on GHC the library and doesn\u0027t start web servers.\n\n_Acknowledgements:_ This project incorporates significant work from [JPMoresmau](https://github.com/JPMoresmau), who is listed as a co-author.\n\n### Using it\n\nRun `stack install ghcid` or `cabal update \u0026\u0026 cabal install ghcid` to install it as normal. Then run `ghcid \"--command=ghci Main.hs\"`. The `command` is how you start your project in `ghci`. If you omit `--command` then it will default to `stack ghci` if you have the `stack.yaml` file and `.stack-work` directory, default to `ghci` if you have a `.ghci` file in the current directory, and otherwise default to `cabal repl`.\n\nPersonally, I always create a `.ghci` file at the root of all my projects, which usually [reads something like](https://github.com/ndmitchell/ghcid/blob/master/.ghci):\n\n    :set -fwarn-unused-binds -fwarn-unused-imports\n    :set -isrc\n    :load Main\n\nAfter that, resize your console and make it so you can see it while working in your editor. On Windows you may wish to pass `--topmost` so the console will sit on top of all other windows. On Linux, you probably want to use your window manager to make it topmost or use a [tiling window man",
