This describes the workflow to use Heroku as a staging environment. It assumes you already have an existing heroku app in production.
# rename your git remote heroku to something else like production
git remote rename heroku production
# so now you will push as: git push production master
# create the staging app
heroku apps:create staging-appname

"""Pexpect is a Python module for spawning child applications and controlling | |
them automatically. Pexpect can be used for automating interactive applications | |
such as ssh, ftp, passwd, telnet, etc. It can be used to a automate setup | |
scripts for duplicating software package installations on different servers. It | |
can be used for automated software testing. Pexpect is in the spirit of Don | |
Libes' Expect, but Pexpect is pure Python. Other Expect-like modules for Python | |
require TCL and Expect or require C extensions to be compiled. Pexpect does not | |
use C, Expect, or TCL extensions. It should work on any platform that supports | |
the standard Python pty module. The Pexpect interface focuses on ease of use so | |
that simple tasks are easy. |

I use tmux splits (panes). Inside one of these panes there's a Vim process, and it has its own splits (windows).
In Vim I have key bindings C-h/j/k/l
set to switch windows in the given direction. (Vim default mappings for windows switching are the same, but prefixed with C-W
.) I'd like to use the same keystrokes for switching tmux panes.
An extra goal that I've solved with a dirty hack is to toggle between last active panes with C-\
.
Here's how it should work:
