Puppet Color Prompt

Overview

This module adds colors to the user and host portions of the PS1 prompt.

Module Description

This module adds a script to /etc/profile.d to insert terminal colors into your PS1 prompt variable. This is useful to help differentiate production system prompts from local prompts.

You haven't lived until you've accidentally shut down a production system! ;)

Usage

Basic Usage

This will install the colorprompt script with the default settings. This will only color the user portion of the prompt when you are root.

include ::colorprompt

Production System in Red

This is what you might define for a production system that should show a red hostname and prepend a red 'PRD' to your prompt:

class { '::colorprompt':
  env_name   => 'PRD',
  env_color  => 'red',
  host_color => 'red',
}

Available Colors

This module supports the basic colors of an 8-color terminal, which should be pretty universally supported:

• black
• red
• green
• yellow
• blue
• magenta
• cyan
• white

All of these are also available as background colors by adding 'bg_' to the beginning of the color name, eg bg_yellow.

A few styles are also supported:

• bright
• faint
• underline
• blink

Combining Colors

You can combine multiple colors and styles by defining an array instead of just a string. For example, this monstrosity:

class { '::colorprompt':
  env_name  => 'ATROCIOUS',
  env_color => [ 'underline', 'green', 'bg_red' ],
}
