-- mod-version:3
-- Orginal Author: Jipok
-- Modified by: techie-guy
-- Doesn't work well with scaling mode == "ui"
-- This is an extension/modification of the nonicons plugin, https://github.com/lite-xl/lite-xl-plugins/blob/master/plugins/nonicons.lua
-- Any icon can be searched by it's hex from nerdfonts.com/cheat-sheet
-- How to use:
-- 1. Download a nerd font that you like from nerdfonts.com
-- 2. Unzip the zip file that you downloaded.
-- 3. Choose a font file from the unzipped directory and install it.
-- 4. Copy the font file to the .config/lite-xl/fonts and rename it to "icon-nerd-font.ttf".
-- 5. Restart lite-xl, the icons should appear.
