d2o (heavy water) is an experimental web server inspired by the h2o project. The main feature of d2o is its unique ICF configuration format, which uses inheritance and string substitution as the primary means of managing websites.
Instead of spawning endless blocks and drowning in location/, I just use pipelines. My entire server, with all subdomains, TLS, and proxying, fits into 12 lines that read from top to bottom. If a folder exists in $WWW, it automatically becomes a site through named wildcards. It’s not magic, it’s just the absence of unnecessary noise in a system that doesn’t try to appear more complex than it is.
