How I use Ghcid in a stack project

1. Install ghcid with cabal install ghcid

2. Add the ghcid neovim plugin to ~/.config/nvim/init.vim: Plugin 'ndmitchell/ghcid', { 'rtp': 'plugins/nvim' }

3. Close neovim and reopen it and run :PluginInstall to install the plugin.

4. Open a stack project in neovim and open a Haskell file (a file with a .hs extension)

5. Run Ghcid with :Ghcid --restart=[project].cabal -c "stack repl --ghci-options=-fno-code" where [project] is the name of the project. If you want to load tests (but not load the app/Main module), run :Ghcid.

6. Now whenever you add new files or update the dependencies, open a new terminal in neovim and run stack build. Ghcid will automatically restart and watch the new modules/dependencies.

7. To delete a module you have to follow these steps:

   1. Edit the [project].cabal file and remove the modules that you want to delete
   2. Delete the files/directories which correspond to the deleted modules
   3. Delete the [project].cabal file
   4. Run stack build
