I am prepared to do some work on Qt Assistant, and I'd like to know how that
will be received.
Cool, great you want to tackle this 😊

I'm sure Jarek (the official maintainer) will also share his thoughts, but he's out
of office this week.

Jarek, could you please review this thread[1] and share your thoughts?

One aspect to keep in mind is that although sharing code with QtCreator and/or using Qt WebView may sound like a better end solution than writing a WebEngine plugin to Assistant, it probably won't address the primary reason for writing the plugin, which is build order. Assistant is currently built before Qt WebEngine, which is why the existing patch[2] does not work in a clean checkout. If we were to switch to Qt WebView, I assume compilation of Assistant would have to be postponed just the same. The best solution would therefore be, in my opinion, to change the order of compilation, apply the existing patch, and consider refactorings and unifications thereafter.

I’m not Jarek, but I recall that Eddy made a suggestion [1] which I think has been prematurely dismissed or at least not been discussed sufficiently, which is:

* move the Qt Assistant functionality for searching and qch support into a locally executed HTTP server
* use any proper webbrowser to display the help that this web service serves

What would be arguments against such a solution?
