I have the Clipboard Indicator GNOME shell extension installed. How can I create another instance of the extension (for development purposes)?

I created a fork of the original project and cloned the files to


I renamed my working directory to clipboard-indicator@rahi.ca, as the original extension is named clipboard-indicator@tudmotu.com.

I restarted the GNOME shell using Alt + F2 and then r. When I try to enable my cloned extension using the Tweak tool, I do not see a second Clipboard Indicator toggle.

I'm running Ubuntu 16.04 with GNOME shell 3.18.5.


Open the metadata.json file located at
and put "clipboard-indicator@rahi.ca" for the "uuid" entry so that it looks like

"uuid": "clipboard-indicator@rahi.ca",

(i.e. it should match the directory containing the metadata.json file).
You may also want to change the value for the "name" parameter.

Then save the file and restart GNOME shell (or re-login).

Then you should find another instance of the extension in Tweaks > Extensions (I renamed it "Clipboard Indicator for development"):

enter image description here

  • I gave this a try and unfortunately it did not work. – rahi Apr 5 '18 at 12:18
  • @rahi Works pretty well for me: i.stack.imgur.com/NaEIO.png. Should not be necessary, but try changing the "name:" too in metadata.json. – pomsky Apr 5 '18 at 13:04
  • @pmsky YES! changing the name did it! – rahi Apr 5 '18 at 14:12
  • sorry off topic. Can you point us to the theme you're using? – rahi Apr 5 '18 at 16:05
