How to add a Line Widget?

[boweihan]

Hi friends,

I'm looking to add a Github code commenting interface to my implementation of react-ace.

I found that ace originally supported line widgets - https://github.com/ajaxorg/ace/blob/v1.1.8/lib/ace/line_widgets.js#L82 - for this purpose.

I understand that we can access the underlying ace ref through react refs - how do I implement something like a line-widget? Are widgets available to be imported?

Thanks!
