@mashihua, thank you for the script and @geraldvillorente for installation instructions!
Could you please give instruction how to use it?
The regexp seems to expect the card ID as an integer number. But currently trello cards have alphanumeric IDs (e.g. https://trello.com/c/rYgiTbGG/).

The script works great, thank you!
But quite often the data is empty string (though the commit message is not empty). If I try to commit & undo several times, finally it works. Has this happened to anybody?
