# hakyll-nix-template
|
||
|
|
|
||
|
|
[Hakyll](https://jaspervdj.be/hakyll/) + [Nix](https://nixos.org) template
|
||
|
|
|
||
|
|
## Quick tips
|
||
|
|
|
||
|
|
* Read the tutorial to get started! https://robertwpearce.com/the-hakyll-nix-template-tutorial.html
|
||
|
|
* If you make changes to anything inside of `ssg/`, you'll need to clean the
|
||
|
|
hakyll cache and rebuild. This is the preferred series of commands for
|
||
|
|
rebuilding (with logs), cleaning the cache, and re-running the dev server:
|
||
|
|
|
||
|
|
```default
|
||
|
|
nix build --print-build-logs && \
|
||
|
|
nix run . clean && \
|
||
|
|
nix run . watch
|
||
|
|
```
|
||
|
|
|
||
|
|
## Features
|
||
|
|
|
||
|
|
* Build your site into the `./result/dist` folder:
|
||
|
|
```
|
||
|
|
λ nix build
|
||
|
|
```
|
||
|
|
* Start hakyll's dev server that reloads when changes are made:
|
||
|
|
```
|
||
|
|
λ nix run . watch
|
||
|
|
Listening on http://127.0.0.1:8000
|
||
|
|
...more logs
|
||
|
|
```
|
||
|
|
* Run any hakyll command through `nix run .`!
|
||
|
|
```
|
||
|
|
λ nix run . clean
|
||
|
|
Removing dist...
|
||
|
|
Removing ssg/_cache...
|
||
|
|
Removing ssg/_tmp...
|
||
|
|
```
|
||
|
|
* Start a development environment that
|
||
|
|
* has your shell environment
|
||
|
|
* has `hakyll-site` (for building/watching/cleaning hakyll projects)
|
||
|
|
* has `hakyll-init` (for generating new projects)
|
||
|
|
* can have anything else you put in the `shell.buildInputs` of the
|
||
|
|
`hakyllProject` in `flake.nix`
|
||
|
|
* is set up to run `ghci` with some defaults and the modules loaded so you can
|
||
|
|
make your own changes and test them out in the ghci REPL
|
||
|
|
|
||
|
|
```
|
||
|
|
λ nix develop
|
||
|
|
|
||
|
|
[hakyll-nix]λ hakyll-site build
|
||
|
|
...
|
||
|
|
Success
|
||
|
|
|
||
|
|
[hakyll-nix]λ ghci
|
||
|
|

|

|
|
All of this is custmomizable, and here are some things that are already done for
|
||
|
|
you:
|
||
|
|
|
||
|
|
* [pandoc](https://github.com/jgm/pandoc/) markdown customization to make it as
|
||
|
|
close to GitHub's markdown style as possible
|
||
|
|
* [`slugger`](https://hackage.haskell.org/package/slugger) module is included that makes nice link URIs based on post titles
|
||
|
|
* RSS & Atom XML feed generation
|
||
|
|
* Sitemap generation
|
||
|
|
* Code syntax highlighting customization
|
||
|
|
* ...other reasonable defaults
|
||
|
|
|
||
|
|
Configure the dev server, cache & tmp directories, and more in
|
||
|
|
`./ssg/src/Main.hs`.
|
||
|
|
|
||
|
|
### Deployment
|
||
|
|
|
||
|
|
Deployment is set up through a [GitHub
|
||
|
|
Action](https://github.com/features/actions) with [cachix](https://cachix.org),
|
||
|
|
and it deploys to a [GitHub Pages](https://pages.github.com/) branch,
|
||
|
|
`gh-pages`, when you merge code into your main branch.
|
||
|
|
|
||
|
|
Setup information can be found below in the "Cachix" section.
|
||
|
|
|
||
|
|
Note: If your main branch's name isn't `main`, ensure `'refs/heads/main'` gets
|
||
|
|
updated to `'refs/heads/my-main-branch'` in `./github/workflows/main.yml`.
|
||
|
|
|
||
|
|
## Setup
|
||
|
|
|
||
|
|
### Nix & Flakes
|
||
|
|
|
||
|
|
If you don't have [nix](https://nixos.org), follow [the nix installation
|
||
|
|
instructions](https://nixos.org/download.html).
|
||
|
|
|
||
|
|
Once you have nix installed, follow the instructions here to get access to
|
||
|
|
flakes: https://nixos.wiki/wiki/Flakes.
|
||
|
|
|
||
|
|
### Cachix
|
||
|
|
|
||
|
|
The `./.github/workflows/main.yml` file builds with help from
|
||
|
|
[cachix](https://app.cachix.org), so you'll need to generate a signing key to be
|
||
|
|
able to do this.
|
||
|
|
|
||
|
|
1. Create a cache on cachix for your project
|
||
|
|
1. Follow cachix's instructions to generate a signing keypair
|
||
|
|
1. Copy the signing keypair value to a new `CACHIX_SIGNING_KEY` secret on
|
||
|
|
