feat(users/sterni/nix): cursed nix html DSL r/2784
Couldn't sleep, so I made a surprisingly neat way to render HTML
documents in Nix using our favorite feature __findFile:
let
inherit (depot.users.sterni.nix.html) __findFile esc;
in
<html> {} [
(<head> {} [
(<meta> { charset = "utf-8"; } null)
(<title> {} (esc "hello"))
])
(<body> {} [
(<h1> {} (esc "hello world"))
])
]
=> "<html><head><meta charset=\"utf-8\"/><title>hello</title></head><body><h1>hello world</h1></body></html>"
