easyconf-lemonbar (eclb)

A python script to easily configure lemonbar.

Signals

You may update individual modules by sending a real-time signal to the easyconf-lemonbar process. First, in the module configuration, specify which signal to listen for, e.g.

# Display a random number, and only update when we recieve the RTMIN+1 signal.
- name: "random"
  command: "python -c 'from random import randrange; print(randrange(1000))'"
  refresh: 0
  signal: 1

In the example above, the refresh is 0. This means that the module will never refresh on its own; it will wait for the RTMIN+1 signal. You may also configure your module to both refresh on a time interval AND listen for a signal.

Unfortunately, to send the signal, you cant just pkill easyconf-lemonbar. You have to read the PID from eclb's pidfile. I would recommend creating an alias in your shell as shown below.

$ alias eclb_kill="cat /run/user/${UID}/easyconf-lemonbar.pid | xargs kill"
$ eclb_kill -RTMIN+1

This will refresh the module that is listening for signal 1. To kill eclb completely, just run eclb_kill (after setting the above alias).
