Is it possible to develop plugins, modules and extensions for Sublime Text 3 and beyond using C++? If yes, where can I find documentation?
No, at this moment. And I think the team declined to do it from what I heard on github.
many python libraries make use of compiled c++ components, so that’s always an option
I needed graphical front-ends for GDB (like DDD) and the “coz-profiler”. I don’t think anyone can build such plugins/modules/extensions using Python.
