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)

Code
-- 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


-- Install package manager
--    https://github.com/folke/lazy.nvim
--    `:help lazy.nvim.txt` for more info
local lazypath = vim.fn.stdpath 'data' .. '/lazy/lazy.nvim'
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system {
    'git',
    'clone',
    '--filter=blob:none',
    'https://github.com/folke/lazy.nvim.git',
    '--branch=stable',
    lazypath,
  }
end
vim.opt.rtp:prepend(lazypath)
