Nelisp

The Neovim Emacs LISP interpreter.

[!NOTE] This is a work in progress.

Init

-- Remember to run `make` once.

-- The `nelisp.c` module is a wrapper around `nelisp.so` using `package.loadlib`.
-- Run `make` to generate a meta file for completions.
local c = require'nelisp.c'

-- Emacs doesn't really give this path a name, so I call it emacs's runtime path.
-- It is the parent directory of the `data-directory` and the parent directory of root load path.
-- Typically, either `/usr/share/emacs/30.1/`(or local variant) or the git repo's root.
c.init({runtime_path = EMACS_RUNTIME_PATH})

c.eval[[
(message "Hello World!")
]]

Goals

• Being able to run emacs plugins such as magit and org-mode
• Performant(fast) loading of elisp-stdlib (100-200ms)

Roadmap

• Rewrite in C (old-lua-branch)
• Implement all functions(/other features) to be able to load all of loadup.el without errors
• Implement dumping
• Implement a bridge between nelisp and neovim
• Implement the rest of the functions(/other features); make all emacs test pass
