Color LS

forthebadge forthebadge

Gem Version Build Status PRs Welcome Stories in Ready

A Ruby script that colorizes the ls output with color and icons. Here are the screenshots of working example on an iTerm2 terminal (Mac OS), oh-my-zsh with powerlevel9k theme and powerline nerd-font + awesome-config font with the Solarized Dark color theme.


If you're interested in knowing the powerlevel9k configuration to get this prompt, have a look at this gist.

  1. Install Ruby (preferably, version > 2.1)

  2. Install the patched fonts of powerline nerd-font and/or font-awesome. Have a look at the Nerd Font README for more installation instructions.

    Note for iTerm2 users - Please enable the Nerd Font at iTerm2 > Preferences > Profiles > Text > Non-ASCII font > Knack Regular Nerd Font Complete.

  3. Install the colorls ruby gem with gem install colorls

    Note for rbenv users - In case of load error when using lc, please try the below patch.

    rbenv rehash
  4. Enable tab completion for flags by entering following line to your shell configuration file (~/.bashrc or ~/.zshrc) :

    source $(dirname $(gem which colorls))/tab_complete.sh
  5. Start using colorls 🎉

  6. Have a look at Recommended configurations and Custom configurations.

Recommended configurations

(Back to top)

  1. To add some short command (say, lc) with some flag options (say, -l, -A, --sd) by default, add this to your shell configuration file (~/.bashrc, ~/.zshrc, etc.) :

    alias lc='colorls -lA --sd'
  2. For changing the icon(s) to other unicode icons of choice (select icons from here), change the YAML files in a text editor of your choice (say, subl)

    subl $(dirname $(gem which colorls))/yaml

Custom configurations

(Back to top)

You can overwrite the existing icons and colors mapping by copying the yaml files from $(dirname $(gem which colorls))/yaml into ~/.config/colorls, and changing them.

  • To overwrite color mapping :

    Please have a look at the list of supported color names. Let's say that you're using the dark color scheme and would like to change the color of untracked file (??) in the --git-status flag to yellow. Copy the defaut dark_colors.yaml and change it.

    cp $(dirname $(gem which colorls))/yaml/dark_colors.yaml ~/.config/colorls/dark_colors.yaml`

    In the ~/.config/colorls/dark_colors.yaml file, change the color set for untracked from darkorange to yellow, and save the change.

    untracked: yellow
  • To overwrite icon mapping :

    Please have a look at the list of supported icons. Let's say you want to add an icon for swift files. Copy the default files.yaml and change it.

    cp $(dirname $(gem which colorls))/yaml/files.yaml ~/.config/colorls/files.yaml`

    In the ~/.config/colorls/files.yaml file, add a new icon / change an existing icon, and save the change.

    swift: "\uF179"
