# About
Hix is a toolkit for Haskell development that uses [Nix](https://nixos.org/learn.html) to provide a unified,
declarative interface for a range of build related tasks:
- Reproducible environments and dependency overrides
- Cabal file generation
- Hackage upload
- Rapid-recompilation testing with `ghcid`
- Haskell Language Server
- CTags generation
- Virtual Machines for testing
- Compatibility checks for multiple GHC versions
To learn more, please visit the [documentation page](https://tryp.io/hix/index.html).
# tldr
You can convert an existing project with Cabal files by executing this command in the project root, using
[FlakeHub](https://flakehub.com/docs) or GitHub:
```
nix run 'https://flakehub.com/f/tek/hix/~0.7.tar.gz#bootstrap'
nix run 'github:tek/hix?ref=0.7.1#bootstrap'
```
You can create a new project in the current directory:
```
nix run 'https://flakehub.com/f/tek/hix/~0.7.tar.gz#new' -- --name 'project-name' --author 'Your Name'
```
The manual process consists of first adding Hix to your Haskell project flake by specifying the input:
```nix
{
inputs.hix.url = "https://flakehub.com/f/tek/hix/~0.7.tar.gz";
}
```
Then configure your project with NixOS module options:
```nix
{
description = "Example";
inputs.hix.url = "https://flakehub.com/f/tek/hix/~0.7.tar.gz";
outputs = {hix, ...}: hix {
packages.parser = {
src = ./.;
library = {
enable = true;
dependencies = ["aeson ^>= 2.0" "bytestring"];
};
executable.enable = true;
test.enable = true;
};
};
}
```
Now generate Cabal files with:
```
nix run .#gen-cabal
```
Build the package with `nix build`, or run the tests in `test/Main.hs` in GHCid:
```
nix run .#ghcid -- -p parser
```
