A small org file to keep track of some metric in a table, see [[https://orgmode.org/manual/Results-of-Evaluation.html][Results of Evaluation]] in the Org mode manual for more information. It's important that the function is supposed to return a list in order to record the result as a table row.

In this case, count the number of packages in my Emacs init file. It is executed automatically when the task is marked as done, using [[https://apps.bram85.nl/gitea/bram/gists/src/branch/main/gists/evaluate-code-on-task-state-change.org][this function]].

Press =C-c C-c= inside the code block to add a new entry to the table below.
