LuaPatch cheat sheet lists every method in the patch chain (
:Named,:Needs,:Requires,:Early, and the rest) with a one-line description, grouped by what it does.Enums lists the named value sets you will run into in part, science, and resource fields (engine types, part categories, resource flow modes, and so on).
Glossary defines the terms the docs use: label, address, converter, pass, bucket, namespaced id, summary, and more.
For the full field list of any asset, use the .d.lua stubs through autocomplete rather than a written table. See Setting up your editor.
