Modular editing levels and towers for Emacs.
Rigpa allows you to construct structures relating editing modes (these could be evil modes or hydras, or anything implementing a common modal interface ("chimera")) and manipulate which structures are active at any point in time. It generalizes both vim's notion of editing mode, as well as Emacs's notion of a major mode into a unified way of looking at things, that is, as towers of modes which can be swapped and themselves edited using the very modes they contain.
In addition, rigpa also defines conventions that modes should follow in order to be seamlessly integrated into editing structures. This includes conventions around keybindings for moving up and down the hierarchy of editing levels, standard semantics of modifier keys, defining a canonical action for each mode, and other such conventions to ensure semantic uniformity across editing levels.
This package isn't on MELPA yet, but you can install a pre-release version using straight.el by putting this somewhere in your .emacs.d:
