Thanks, @cclauss! * Dictionary lookup of event loop actions This was kind of an experiment that adds lots of blank lines to this script -- feel free to reject it. The observation that triggered this was that in main() all actions can execute using just one parameter, args. This means that it is possible to use args.action to do a dict lookup to get the corresponding function. This approach adds tons of blank lines to the script in exchange for a rapid seek to the action implementation and a substantial reduction of the McCabe complexity of main(). $ __flake8 . --count --exit-zero --max-complexity=10 --max-line-length=127 --statistics__ ``` ./pmbootstrap.py:43:1: C901 'main' is too complex (23) ./pmb/aportgen/core.py:38:1: C901 'rewrite' is too complex (17) [ ... ] ``` * Remove action_dict and use locals() instead
