I've been enjoying a featherweight alternative to log levels, made possible by org-mode.

Try this the next time you write a little throwaway command-line utility script:

Step 1: Add asterisks to the front of your printf traces.

Step 2: Tee your STDOUT / STDERR to a file named log.org

Step 3: Open the log file in org-mode.

Step 4: Rejoice!

Optional: You can tail the logfile with M-x auto-revert-mode.

This illustration uses a Github scraper as an example:

This is no substitute for real structured logging, of course :)

That is all.
