Question

I have a thor-based Ruby script, but I want to deploy it as a gem in people’s bin directories that people can hit without having to do thor mytool.

So instead they’d just use mytool

Is this possible?

I know it’s possible with vanilla optparse but I’d rather use Thor if possible.

Update: This is the code I’m using based on the example on the Thor page, but I get the error below:

#!/usr/bin/env thor

class App < Thor
  map "-L" => :list

  desc "install APP_NAME", "install one of the available apps"
  method_options :force => :boolean, :alias => :string
  def install(name)
    user_alias = options[:alias]
    if options.force?
      # do something
    end 
    # other code
  end 

  desc "list [SEARCH]", "list all of the available apps, limited by SEARCH"
  def list(search="")
    # list everything
  end 
end

Error:

Make the shebang line

#!/usr/bin/env ruby

and then at the end of your script add

App.start
