Code navigation via ctrl+click keyword

[pfergiu]

Like in most of professional IDEs, it could be great to add a new feature that brings you to the class or function declaration in code or library, only pressing control key and clicking in a highlighted keyword.

I think it would be nice if that was also extended to includes, giving the ability to view them in RO mode. i saw that 1.9.0 offers a nice workaround there, with code completion, but looking at a lib code is full of insights when starting

It is possible to crudely extend the patch Ricardo created in SketchTextArea to make it identify include references and fire custom URL protocol (here I called it 'aide' for 'arduino ide') reference containing the data to be displayed (the server name is 'absolute' or 'relative'). With a dummy protocol handler, the following will be displayed:

    Pattern regex = Pattern.compile("([\"<])([\\w./]+)[\">]");
    private Optional<HyperlinkEvent> getIncludeReference(Token t) {
      int begin = t.getOffset();      
      Token n1 = t.getNextToken();
      try {
        String line = getTextLine(t);
        Matcher m = regex.matcher(line);
        if (m.find()) {
          String desc = null;
          try {
            String svr = m.group(1).equals("<") ? "absolute" : "relative";
            URL url = new URL("aide", svr, m.group(2));
            HyperlinkEvent evt = new HyperlinkEvent(SketchTextArea.this, HyperlinkEvent.EventType.ACTIVATED, url, "blah blah");
            return Optional.ofNullable(evt);
          } catch (MalformedURLException mue) {
            desc = mue.getMessage();
          }
        }
      } catch (BadLocationException e) {
      }
      return Optional.empty();
    }
