Base16 themes integration

This folder contains a couple of files that let you configure Nushell and other terminal tools to use base16 themes.

Requirements

Assumes a Linux system with an X-based window manager. Specific packages and environment variable requirements are listed in each file.

Files explanation

  • base16.nu - Main module -- see comments inside
  • auto_base16.nu - Generates a base16 theme from a wallpaper
  • alacritty_colors.template - Template for Alacritty terminal colors

Example integration

Fist, set up base16 theme generation from a wallpaper:

# ~/.xinitrc

...

[ -f ~/.auto_base16.nu ] && ~/.auto_base16.nu &

This will generate a base16 theme to a file from a current wallpaper. You can combine this with a random wallpaper generation using the fehbg.nu script for more chaos fun.

Next, set up Nushell config, assuming the base16 colors are generated

# config.nu

use ~/.config/nushell/base16.nu

# File containing base16 colors
$env.BASE16_TXT = "/tmp/base16.txt"

let config = {
    color_config: (base16 build-nu-config $env.BASE16_TXT)
}

To select a new wallpaper and regenerate the base16 config:

> base16 new-wallpaper

> source ~/.config/nushell/config.nu
