This package adds support to Org-Babel for evaluating Python source code using IPython.

This package provides a major mode that let the user interact with SWI-Prolog in all buffers. For instance, one can consult Prolog programs and evaluate embedded queries. This mode is focused on the command ediprolog-dwim (Do What I Mean) which is supposed to, depending on the context, carry out the appropriate action.

This package allows items in the Org agenda to be grouped into sections while preserving the structure imposed by any timestamps.

crdt.el is a real-time collaborative editing environment for Emacs using Conflict-free Replicated Data Types. With it, you can share multiple buffer in one session, and see other users’ cursor and region. It also synchronizes Org mode folding status. It should work with all of Org mode.
