# Setup notes
## Nix
You need an installation of the [Nix package
manager](https://nixos.org/download.html#download-nix), with `flakes`
enabled (see [the NixOS wiki](https://nixos.wiki/wiki/Flakes) for
instructions).
## VSCode
There are (at least) three alternative possibilities to get LSP
integration for Haskell working seamlessly. Install the following
extensions first:
- `haskell.haskell`
- `bbenoist.nix`
Then choose one of the following methods, with the first being the
simplest:
### Starting `code` from within a Nix environment
- Enter the Nix development environment via `nix develop`
- Then execute `code .`
- Open the `MyLib.hs` file and change something; after a while, you
should see some LSP feedback
### `direnv`
- Install [direnv](https://direnv.net/)
- Install the `mkhl.direnv` plugin in VSCode
- When opening the repository, the plugin will ask you to `Allow`
usage of the `.envrc` file that already exists -> accept this
- Now you should see a prompt asking you to restart the extension ->
also accept this
- Open the `MyLib.hs` file and change something; after a while, you
should see some LSP feedback
### Nix environment selector
- Install the plugin `arrterian.nix-env-selector`
- After opening the repository, choose `Nix-Env: Select environment`
from the command palette
- You should be prompted for a `Reload` -> accept this
- Open the `MyLib.hs` file and change something; after a while, you
should see some LSP feedback
