Atom.io with Nuclide : Line marker

Question

Before I reset my mac, While using Atom ( with nuclide plugin installed ) I was able to mark lines. ( clicking on left side of line numbers ).

After resetting my mac and installing Atom, I can't find that option. I also tried many Atom plugins but I couldn't find it. Please see the screenshot attached bellow ( I've putted dots on image to show what was it look like ).

Do you know the option / plugin name?

Thanks in advance!

Answer 1

This is from the Nuclide plugin and it's a Breakpoint. It's found in the nuclide-debugger feature.

For this to work, make sure the nuclide-debugger feature is active in Nuclide's config (Settings » Packages » Nuclide):

To add a breakpoint to a line, click the gutter (as you tried), or press F9.

Answer 2

Too late answer but still useful.
