I'm trying to integrate ipython and vim through a single tmux session using the popular vim plugin "vim-slime." The problem is that while I can get it to work fine provided that vim is opened in a separate tmux window (or using gvim), if I try to send lines of code to a different pane in the same window, at best I wind up sending it to the vim session I'm currently using.
Really what I want in my setup is vim on the right-hand side of the screen, ipython on the upper-left, and a regular command-line on the bottom left. I don't really want to be opening and managing multiple sessions and windows.
Is there a simple way to do this that I just don't know about because of my relative inexperience?
