-- Stand-alone neovim config file with all my defaults

--TODO:
-- fix "$nv/after/syntax/gcode.vim"
-- fix clipboard
--- yanking text always copies it to system clipboard as well as the local instance clipboard
-- remove highlights after search
-- highlights only in current buffer
-- add better pair matching functionality to replace:
--- [matchit](https://github.com/neovim/neovim/blob/master/runtime/pack/dist/opt/matchit/plugin/matchit.vim) &
--- [vim-surround](https://github.com/tpope/vim-surround)
-- builting support for markdown style lists

-- Language Configs: (in order)
--- Lua, C, Rust, Zig
