Why won't the Launchy gem work in Shoesrb?

I can't seem to get the button to open the url in a browser. The script runs in Shoes, however the button does not do anything. What am I doing wrong?

Shoes.setup do
  gem 'launchy'
end

require 'launchy'

Shoes.app do
    background "#EFC"
    border("#BE8",
           strokewidth: 6)

    stack(margin: 12) do
      para "Enter ID"
      flow do
        @e = edit_line

        id = @e.text

        fburl = "http://www.facebook.com/profile.php?id="

        #alert fburl+id

        button "OK" do
        Launchy.open("#{fburl}+#{id}")



      end
    end
  end
end

After making the suggested changes and using "shoes.setup do", I get the following error:

undefined method 'dir for Gem:Module :344:in 'method_missing' C:/Program Files (x86)/Common Files/Shoes/O.r1514/ruby/lib/rubygems/installer.rb:97:in 'initialize' C:/Program Files (x86)/Common Files/Shoes/O.r1514/lib/shoes/setup.rb:265:in 'new' C:/Program Files (x86)/Common Files/Shoes/O.r1514/lib/shoes/setup.rb:265:in 'install_sources' C:/Program Files (x86)/Common Files/Shoes/O.r1514/lib/shoes/setup.rb:27:in 'init C:/Program Files (x86)/Common Files/Shoes/O.r1514/lib/shoes/setup.rb:329:in '' C:/Program Files (x86)/Common Files/Shoes/O.r1514/lib/shoes.rb:105:in 'require' C:/Program Files (x86)/Common Files/Shoes/O.r1514/lib/shoes.rb:105:in 'setup' Shoes Gem Loader.rb:1:in '' C:/Program Files (x86)/Common Files/Shoes/O.r1514/lib/shoes.rb:428:in 'eval' C:/Program Files (x86)/Common Files/Shoes/O.r1514/lib/shoes.rb:428:in 'visit' C:/Program Files (x86)/Common Files/Shoes/O.r1514/lib/shoes.rb:118:in 'show_selector C:/Program Files (x86)/Common Files/Shoes/O.r1514/lib/shoes.rb:151:in 'block (4 levels in splash' (null):0:in 'call'

Am I to assume that launchy is not a usable gem in Shoes?

Solution

  • The "original" Shoes doesn't play well with gems. The newest version of Shoes (Shoes 4) lets you require gems normally. It's pre-alpha, but almost feature-complete. Here's your code modified to run in Shoes 4. Note that the id assignment has to be moved into the button block (but this would be necessary for any version of Shoes)

    require 'launchy'

Shoes.app do
  background "#EFC"
  border("#BE8", strokewidth: 6)

  stack(margin: 12) do
    para "Enter ID"
    flow do
      @e = edit_line

      fburl = "http://www.facebook.com/profile.php?id="

      button "OK" do
        id = @e.text
        alert fburl+id
        Launchy.open("#{fburl}+#{id}")
      end
    end
  end
end

    To install Shoes 4, follow the instructions on GitHub, and make sure you gem install launchy. Then you should be able to run your app.
