wal color theme

Link: https://github.com/dylanaraps/pywal

The repository was archived. But the functions sill work.

Original name call wal, then it change to call pywal.

It is a tool for generate and change color-schemes for system or some software

Use this command to checkout all the avaliable themes

wal --theme

The most interesting command is it can pass image file and base on image tone to get match theme scheme.

So I used this command to switch the background image from folder randomly and generate color scheme:

wal -i ~/wallpaper

It will show the change on your terminal immediately.

Here is my wrapper script that randomly select themes I like.

#!/bin/bash

# Check if 'wal' is not installed
if ! command -v wal &> /dev/null; then
  echo "Error: 'wal' is not installed. Please install pywal first."
  exit 1
fi

wal_log="/tmp/wal-theme"
