Command::Dispatcher

Code Climate

Installation

Add this line to your application's Gemfile:

gem 'command-dispatcher'

And then execute:

$ bundle

Or install it yourself as:

$ gem install command-dispatcher

Usage

Assume you are writting a cli gem with multiple commands.

With CommandDispatcher you would create a first cli script and add the following code to it:

mygemscript

$scriptPath = File.expand_path(File.dirname(__FILE__))
$scriptName = File.basename(__FILE__)
$command = ARGV.shift
dispatcher = CommandDispatcher::Dispatcher.new( $scriptPath, $scriptName )

begin
    dispatcher.dispatchCommand($command, *ARGV)
rescue ArgumentError => ex
    $stderr.puts "Error: " + ex.to_s + ".  Please specify a valid command."
    dispatcher.usage
    exit -1
ensure
end

Then for each command, you would create a specific ruby script file name like: mygemscript-commanda mygemscript-commandb mygemscript-commandc

Such that when invoking mygemscript commanda would resolve in calling mygemscript-commanda
