Debugging & Logging¶
Run Extension Separately¶
You don’t have to restart Ulauncher every time a change is made to your extension.
For your convenience there is a flag
--no-extension that prevents extensions from starting automatically.
First, start Ulauncher with the following command:
ulauncher --no-extensions --dev -v
Then find in the logs command to run your extension. It should look like this:
VERBOSE=1 ULAUNCHER_WS_API=ws://127.0.0.1:5050/ulauncher-demo PYTHONPATH=/home/username/projects/ulauncher /usr/bin/python /home/username/.cache/ulauncher_cache/extensions/ulauncher-demo/main.py
Now when you need to restart your extension hit
Ctrl+C and run the last command again.
Here is the easiest way to set a breakpoint and execute code line by line:
- Install ipdb
sudo pip install ipdb
- In your code add this line wherever you need to break
import ipdb; ipdb.set_trace()
- Restart extension
Set up Logger¶
Here’s all you need to do to enable logging for your extension:
import logging # create an instance of logger at a module level logger = logging.getLogger(__name__) # then use these methods in your classes or functions: logger.error('...') logger.warn('...') logger.info('...') logger.debug('...')
