Awesome! 👏 Also, it will be cool to have something online to see how your changes work. Maybe in playground.

@antonmedv Sure, I'll make a demo later. Any ideas on good online playground? :)

Static line numbers bar (now broken) - help needed

Line numbers were fixed in this commit.

Improve line breaks (use universal \r\n instead of \n)

I'm not savvy enough to know when Windows line endings are universally preferred over Unix line endings, but if Unix line endings are kept, then this regex can be simplified to:

code.split(/\n/).length + (code.endsWith('\n') ? 0 : 1)

Either way, it fixes the issue where line numbers aren't added to the end of the editor.

@antonmedv Here are before and after gif's. Observe the line numbers as new lines are added. The first gif was captured using the latest master branch and second gif was captured with the regex fix:

Any progress? Someone what to continue from this PR?
