  • Make VIM users comfortable in Builder
  • Bring powerful modal editing to GtkSourceView


We do not plan on using upstream VIM. Abstracting the source editor is more complexity than we are interested in maintaining. However, implementing VIM modal editing on top of GtkSourceView is something we are interested in.

You can find the implementation of VIM mode here.
