The website is built with Hakyll, which is a Haskell library for generating static sites. The actual content is written in the ReStructured Text and Markdown formats.
Building with Nix
This is much faster than using Cabal.
Use sh watch.sh to run a local test of the site.
Use sh deploy.sh to push it to the web server.
Install futhark-website package first:
cabal install futhark-website.cabal
To build the website:
cabal exec futhark-website build
You can preview with:
cabal exec futhark-website watch
When you are ready to deploy to futhark-lang.org, run:
cabal exec futhark-website deploy
This requires rsync installed locally and your public SSH key added
to the remote server. You can also just push to the Git repository,
where a GitHub Actions job will then take care of building and
deploying to the server.
