Scripting Tmux Layouts

Tmux is an awesome replacement for Screen. I have a couple of standard terminal layouts for programming. One of them is show below.

• Vim editor on the left.
• Top right pane has the bpython interpreter.
• Bottom right pane has the bash prompt.

I have a small tmux script in my ~/.tmux/pdev file that has the following lines

selectp -t 0              # Select pane 0
splitw -h -p 50 'bpython' # Split pane 0 vertically by 50%
selectp -t 1              # Select pane 1
splitw -v -p 25           # Split pane 1 horizontally by 25%
selectp -t 0              # Select pane 0

In my tmux.conf file I have bound +P to sourcing this file. So now anytime I want to launch my python dev layout, I hit ++p. 

bind P source-file ~/.tmux/pdev
