Make Nerd fonts work with the Chromebook terminal

Here is a too complicated hack to make Nerd fonts work on the Chromebook terminal. There should be an easier way. Please tell me if you find it.

First we need a CORS compliant web server to fetch the font. I didn't want to have to be online to use the terminal so I'm going to run the server locally. Fetch the server.py file (below) and save it to your linux environment. I put it in ~/hacks/nerdfont/server.py. This little script adds the CORS headers to the python3 http server. It will only serve files from the current folder.

In my ~/.bashrc I added these lines:

# make the nerdfont available to the chromebook terminal

Paste this to use Jetbrais Mono with ligatures:

term_.prefs_.set('font-family', 'JetBrains Mono Nerd Font, monospace');
term_.prefs_.set('user-css-text', '@font-face {font-family: "JetBrains Mono Nerd Font"; src: url("https://raw.githubusercontent.com/ryanoasis/nerd-fonts/master/patched-fonts/JetBrainsMono/Ligatures/Regular/JetBrainsMonoNerdFont-Regular.ttf"); font-weight: normal; font-style: normal;} x-row {text-rendering: optimizeLegibility;font-variant-ligatures: normal;}')

Oh my zsh.

Install ZSH.

sudo apt install zsh-autosuggestions zsh-syntax-highlighting zsh
