`deps.lua` is an all-in-one script containing your declarative list of dependencies and installing any missing ones.

README.md

deps.lua is an all-in-one script containing your declarative list of dependencies and installing any missing ones.

Kind of like Clojure's deps.edn except that the dependencies and code to download them are bundled in one package.

• add link from file to gist so people can find back to here
• add entries to .gitignore if available
• ? if file ends in .fnl, download fennel.lua and compile to respective .lua file location

Usage in a fennel script

This will download moses.lua if it is missing (based on the list of files in deps.lua).

(require "deps")
(local M (require "moses"))
(print M)

📫 Subscribe to the gist for update notifications (unlikely 😂)
