ShellColors is an Oh My Zsh plugin that automatically updates your terminal background color based on the presence of a .shellcolor file in the current directory or one of its parent directories. The plugin also provides a command interface to set, unset, and manage the .shellcolor file.

1. Clone the repository into the custom plugins directory of Oh My Zsh:

   git clone https://github.com/SaltedBlowfish/zsh-shellcolor.git ~/.oh-my-zsh/custom/plugins/shellcolors

2. Add shellcolors to the list of plugins in your .zshrc file:

   plugins=(... shellcolors)

3. Reload your Zsh configuration or restart your terminal session:

   source ~/.zshrc

The plugin automatically updates the terminal background when you change directories. It searches for a .shellcolor file in the current directory and its parent directories; if none is found, it uses the default color.

A command interface is provided via the shellcolor command:

• Set a random color:

  shellcolor set random

  This command generates a random low-saturation color, writes it to .shellcolor, and updates the background.

• Set a specific color:

  shellcolor set #RRGGBB

  Replace #RRGGBB with your desired hexadecimal color code.

• Unset the custom color:

  shellcolor unset

  This command removes the .shellcolor file and reverts to the default background.

• Add .shellcolor to .gitignore:

  shellcolor gitignore

• Reshim (refresh) the background:

  shellcolor reshim

By default, the plugin uses black (#000000) as the default background color if no .shellcolor file is found. To change this, set the DEFAULT_SHELLCOLOR environment variable in your .zshrc file:

1. Open your .zshrc file:

   vim ~/.zshrc

2. Add the following line with your desired default color:

   export DEFAULT_SHELLCOLOR="#yourdefaultcolor"

3. Save the file and reload your Zsh configuration:

   source ~/.zshrc
