My nvim.lua File Dotfile

This is the config I have setup for Neovim. I started with kickstart.nvim then modified to suit my taste. This isn't my full config though, I split out some parts (like keymappings) to their own files. (Those will show up once I get categories working)

July 2023

My options are in [TODO: make ilinks work]. I split them out to make them a little easier to parse.

Code
-- disable netrw via nvim-tree recommendation
vim.g.loaded_netrw = 1
vim.g.loaded_netrwPlugin = 1



-- Update leader to use `,`
-- This must be mapped before rt: requiring 
-- other plugins

vim.g.mapleader = ','
vim.g.maplocalleader = ','


-- Set loaded_matchparen here to ``1`` to disable
-- parenthesis highlighting. This was originaly
-- lower in the file, but it didn't work down
-- there for some reason I haven't looked into

vim.g.loaded_matchparen = 0
