Question

I want to contribute a command to the context menu of any text editor when text is selected. In “the old days”, I would have done this using objectContribution and a nested action with “enablesFor=’+'”.

How does one do this using commands instead of actions?

Answer 1

I read more about the variables available in command expressions, and I came close to figuring it out on my own, but failed. I then asked a similar question on the eclipse newsgroup and was led in the right direction. Here’s an example of how to do mostly what I was looking for:

 <command
      commandId="org.marcesher.blogcodeformatter.commands.wikiFormatterCommand"
      tooltip="Format And Copy to Clipboard"
      id="org.marcesher.blogcodeformatter.popup.wikiFormatterCommand">
    <visibleWhen>
       <with variable="selection">
          <instanceof value="org.eclipse.jface.text.ITextSelection"/>
       </with>
    </visibleWhen>
