title: How to display current values of VS Code's predefined variables (such as "${workspaceFolder}" or "${fileWorkspaceFolder}")?
body: <p>I am facing an issue with VS code debugger while trying to debug some angular typescript source code, and I think the reason is that some of those <a href="https://code.visualstudio.com/docs/editor/variables-reference" rel="noreferrer">VS Code Variables</a> have the wrong value - as suggested <a href="https://stackoverflow.com/a/52391649/1016343">here</a>.</p>
  
  <p>I'd like to follow that advice, but I see no way how to query the VS code variables (e.g. display the current values of these variables for my project).</p>
  
  <p>One of these variables is</p>
  
  <blockquote>
    <p>${workspaceFolder}<br/></p>
  </blockquote>
  
  <p>They are used in VS code's config files, for this example in the <code>launch.json</code> file.</p>
  
  <p>Do you know if there is a way to display those values? For example, log the values or show them in an alert window would just be sufficient for me to troubleshoot it.</p>
