I'm working on a django-based project that uses celery workers in order to run some heavy tasks. Plus, the UI is built using brunch.

So, each time I want to start all the needed services, I have to:

  • Open a bunch of terminals (usually in a tmux session)
  • Enable virtualenv in each terminal
  • Start the django development server
  • Start a celery worker
  • Start the brunch file-watcher service
  • Maybe open a htop too, just to monitor the resources usage

Of course, I'm not going to do that by hand each time. Instead, I wrote a tmux configuration script to do everything by itself, while I sit back and relax :).

This is what I came up with:

#!/usr/bin/tmux source-file

new-session -d
split-window -d -t 0 -v
split-window -d -t 0 -h
split-window -d -t 0 -v
split-window -d -t 2 -v

send-keys -t 0 'workon my_virtualenv' enter C-l
send-keys -t 0 'python manage.py runserver' enter

send-keys -t 1 'htop' enter C-l

send-keys -t 2 'workon my_virtualenv' enter C-l
send-keys -t 2 'python manage.py celery worker --loglevel=info' enter

send-keys -t 3 'workon my_virtualenv' enter C-l
send-keys -t 3 'cd MyProject/webui/' enter
send-keys -t 3 'brunch watch' enter

## Just a convenience shell
send-keys -t 4 'workon my_virtualenv' enter C-l
select-pane -t 4

attach

This will open a tmux session with this layout:

+--------------------+--------------------+
| 0: django server   | 3: brunch watch    |
+--------------------+--------------------+
| 2: celery worker   | 1: htop            |
+--------------------+--------------------+
| 4: Shell for stuff                      |
|                                         |
+-----------------------------------------+

I have no idea on why the panes get numbered that way, but it's ok, once you know the order..

Btw, you can use C-b q in a running tmux to find out which the pane numbers are.
