[GNC-dev] WebKitGtk now defaults to Gtk4

[john]

Adrien,

I haven't looked at those specific recommendations, but a general caution about dependencies: They must either be widely supported by Linux distros or small and simple enough to add to GnuCash itself in the "borrowed" subdirectory. In the latter case it means we've forked the project and own it for any bugs. 

As for internal links: Possible doesn't mean not a ton of work and either somebody with the requisite experience materializing to do it or one of the current core devs learning how.

Regards,
John Ralls

Writing the reports in PDF directly requires a complete rewrite of the report output code that's hardwired to generate HTML using basic scheme text output, plus replacing the javascript-based charts solution with some other library that generates PostScript vector graphics (https://graphviz.org <https://graphvizorg/> comes to mind). That's a pretty big rewrite, probably a solid year of work for an experienced developer with lots of available time and assuming that there's a suitable library to abstract generating the PDF boilerplate.
>> The reason using the web browser to display the html loses the transaction/account links is because they're implemented using a callback function that we can register with WebKitWebViewGtk. That goes away when the browser isn't part of GnuCash. It's not impossible, of course: It should be possible to embed a bit of javascript that calls back to GnuCash on a (new) socket listener that would do the linked action.
