lightdark

Switch between macOS Light and Dark mode in iTerm!

While lightdark is running, switching the system appearance will change the theme in all open terminals.

Requirements:

• iTerm2
• Base16 Shell

Inspiration: https://github.com/sindresorhus/swift-snippets/tree/master/DarkMode.playground

Works well with Shifty

Installation

lightdark requires crystal: brew install crystal

Then, clone this repository:

git clone https://github.com/keidax/lightdark.git
cd lightdark

Build the project:

shards build --release

And optionally, install the binary somewhere on your PATH:

sudo cp ./bin/lightdark /usr/local/bin/lightdark

If you want lightdark to automatically start when you log in, create a plist file like this at ~/Library/LaunchAgents/com.github.keidax.lightdark.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>EnvironmentVariables</key>
        <dict>
                <key>BASE16_SHELL</key>
                <string>~/.config/base16-shell</string>
        </dict>
        <key>KeepAlive</key>
        <true/>
        <key>Label</key>
        <string>com.github.keidax.lightdark</string>
        <key>ProgramArguments</key>
        <array>
                <string>/usr/local/bin/lightdark</string>
                <string>serve</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
</dict>
</plist>

Usage

Use lightdark serve to run the lightdark daemon.

To configure the themes, use environment variables:

Variable	Default
LIGHTDARK_DARK_THEME	gruvbox-dark-hard
LIGHTDARK_LIGHT_THEME	one-light

lightdark toggle can be used to switch the system appearance from any terminal, as an alternative to System Preferences.

Use mesg n if you want to stop receiving theme changes in a particular terminal. Use mesg y to resume.
