A couple of simple Python classes to manage reading from and writing to Lemonbar.
Modules can be either, time based (i.e. update every N seconds), select based (i.e. update when a file descriptor (or anything that select can handle) becomes readable) or event based (i.e. when something on the bar is clicked).
This allows us to do away with polling in a lot of cases!
No modules included, they're simple to write, so get to it ;)
Install with:
pip3 install lemonbar-manager
from lemonbar_manager import Manager, Module
# Create a simple "Hello World" module
class HelloWorld(Module):
def output(self):
"""Output a constant string to the bar.
"""
return 'Hello World'
# Define the modules to put on the bar (in order)
modules = (
HelloWorld(),
)
# The command used to launch lemonbar
command = (
'lemonbar',
'-b', # Dock at the bottom of the screen
'-g', 'x25', # Set the height of the bar
'-u', '2', # Set the underline thickness
)
# Run the bar with the given modules
with Manager(command, modules) as mgr:
mgr.loop()Take a look through the examples directory for a more in-depth look at what's possible.
