title: No launch.json file when trying to run debug in VS code
body: <p>I am trying to get my debug working in VS code for my Ruby code but the instructions do not make sense for me. On the github page it tells me to:</p>
  <blockquote>
  <p>Go to the debugger view of VS Code and hit the gear icon. Choose Ruby or Ruby Debugger from the prompt window, then you'll get the sample launch config in <code>.vscode/launch.json</code>.</p>
  </blockquote>
  <p>But when I open that debugger view in VS code there is no gear icon. I have spent days searching online but I cannot find a solution. I have no auto generated <code>launch.json</code> so I do not know what to put in it even if I create my own.</p>
  <p>Thanks</p>
