# ghcid
|
||
|
|
|
||
|
|
> Simple and efficient CLI IDE for Haskell that reloads code on file changes.
|
||
|
|
> Continuously displays compile errors, warnings, and test results.
|
||
|
|
> More information: <https://github.com/ndmitchell/ghcid>.
|
||
|
|
|
||
|
|
- Start `ghcid` and monitor a Haskell file for changes:
|
||
|
|
|
||
|
|
`ghcid {{path/to/Main.hs}}`
|
||
|
|
|
||
|
|
- Start `ghcid` with a specific command, such as loading a Stack or Cabal project:
|
||
|
|
|
||
|
|
`ghcid --command "{{stack ghci Main.hs}}"`
|
||
|
|
|
||
|
|
- Run an action (default `main`) on each file save:
|
||
|
|
|
||
|
|
`ghcid --run={{action}} {{path/to/Main.hs}}`
|
||
|
|
|
||
|
|
- Set maximum height and width (default to console height and width):
|
||
|
|
|
||
|
|
`ghcid --height={{height}} --width={{width}} {{path/to/Main.hs}}`
|
||
|
|
|
||
|
|
- Write full GHC compiler output to a file:
|
||
|
|
|
||
|
|
`ghcid --outputfile={{path/to/output_file.txt}} {{path/to/Main.hs}}`
|
||
|
|
|
||
|
|
- Execute REPL commands (eg. `-- $> 1+1`) on each file save:
|
||
|
|
|
||
|
|
`ghcid --allow-eval {{path/to/Main.hs}}`
