Most of the applications using languages other than C or C++ are using Python or JavaScript. There are GObject-Introspection annotations for the API that can be used from Web Extensions, so it should be already possible to make extensions in Python/JS. As en example, right now it should be reasonably easy to write a stub Web Extension in C that uses the CPython API to create an interpreter when the Web Extension is initialized, loads a Python script, and calls a function in it passing the WebKitWebExtension and the GVariant received by the initialization function [1]. Another approach would be to teach the WebKitGTK+ injected bundle how to load Python/JS/etc web extensions. The problem I see with this approach is that WebKitWebProcess could end up linking to e.g. libpython, and I would rather avoid linking directly — though maybe dlopen()'ing could be an option. One more option could be using the non-UI part of libpeas [2], as it already includes loaders for Python2, Python3 and Seed (JS). Personally, I would go for having the code for stub Web Extensions that load Python/JS available somewhere in a Git repo, and referenced From a “Porting to WebKit2GTK+”, so developers can grab the code and adapt it to their needs. WDYT? -Adrian
