I had a very specific configuration I was trying to get working for personal usage. After a bunch of running in circles, this was the result. I figured I'd stick it somewhere public in case anyone else finds it useful.

A Quick Guide to Setting up Livebook with Support for livebook:// URLs on Linux

Note that the following steps are intended as a rough outline. They are exact steps to replicate my setup, but your setup might differ depending on, for example, using an init system other than systemd or various other factors. Adjust as necessary.

1. Run docker volume create livebook-data and docker volume create livebook-config.
2. Place the livebook.service file in $HOME/.config/systemd/user.
3. Run systemctl --user enable --now livebook.service.
4. Place the dev.livebook.Livebook.desktop file in $HOME/.local/share/applications.
5. Place the dev.livebook.Livebook.svg file in $HOME/.local/share/icons/hicolor/scalable/apps.

Go/Elixir NIF Experiment

This was a quick little experiment to try to call Go code from Elixir. To try it out, simply run

$ go build -buildmode=c-shared -o nif-test.so
$ iex test.exs

func FormHandler[T any](f func(T) templ.Component) http.Handler {
	return http.HandlerFunc(func(rw http.ResponseWriter, req *http.Request) {
		req.ParseForm()

		var data T
		d := formam.NewDecoder(nil)
		d.Decode(req.Form, &data)
		// TODO: Handle errors.

		templ.Handler(f(data)).ServeHTTP(rw, req)
