Contribute — propose a file extension

Tell us where to find evidence about Essence (mapped to pl/essence). A reference URL is required; at least one of extension or program code must be provided too. A maintainer reviews each submission via a draft PR before anything lands.

File extension (optional) — e.g. .oak. Some PLs (e.g. esolangs) have no convention; leave empty if so. Friendly name (optional)

Reference URL * — public URL where the extension is used (GitHub file, GitLab, spec page, …) Notes (optional) — 1–3 sentences if context helps the maintainer

Optional: attach a program from that URL

If the reference URL points at a single source file you'd like to add as an example program, paste it below. The workflow will write it under languages/Essence/programs/<sha>/. Keep under ~200 lines.

Title (optional) — e.g. "Factorial", "Quicksort" License guess (optional) — MIT, GPL-2.0, …

Code (optional) — paste verbatim bytes from the reference URL

(or open the pre-filled issue directly)
