I’d like to submit ‘lua-ts-mode’ for inclusion. I’m new to all of this
so suggestions for improvements or anything else are very welcome.

There is already ‘lua-mode’ in NonGNU ELPA but this one is copyright FSF
and uses tree-sitter to provide it’s functionality so I hope the
duplication of effort is not a problem.

Thanks.

;;; Commentary:

This package provides ‘lua-ts-mode’ which is a major mode for
editing Lua files that uses Tree Sitter to parse the language.

This package is compatible with and tested against the grammar
for Lua found at https://github.com/MunifTanjim/tree-sitter-lua

With Git, a C compiler and linker in PATH you can install it by
running:

    M-x treesit-install-language-grammar RET lua RET y
    https://github.com/MunifTanjim/tree-sitter-lua RET RET RET RET RET

To automatically enable it when you open a Lua file add the following
to your ‘user-init-file’:

    (add-to-list 'auto-mode-alist '("\\.lua\\'" . lua-ts-mode))
