Opal console are develoment tools for Opal based web apps. It starts off with an “opal console” which is a subclass of opal-irb modified to work as a Chrome devtool. Other features from opal-inspector will be be added over time.
See this article for a fairly comprehensive list of features. Note that “live gists” are not supported, unless I figure out a way to make them work meaningful with a devtool.
Due to having to inject some code into the inspected window, only Opal 0.8 and above are currently supported
