A git hook to keep your emotions in check
Tags: programming, projects
When developing software, especially if working with other people,
emotions may run high at times. Nonetheless, conversations should be
kept as civil as possible. To help you in this regard, here’s a
git hook that performs basic sentiment analysis on your commit
#!/usr/bin/env python # # Checks the input file for negative sentiments and exits with non-zero return # status in case the message appears to be too negative. from afinn import Afinn import sys with open(sys.argv) as f: afinn = Afinn() text = f.read() score = afinn.score(text) if score < -4.0: print( "This commit seems to be written very negatively. You might want\n" "to overthink it and rewrite it. If you are really, really sure,\n" "use\n\n" " git commit --no-verify\n\n" "to skip this check." ) sys.exit(-1)
Install the script by copying it into the local
under the name
commmit-msg. Don’t forget to make the file
$ cp sentiment_analysis.py .git/hooks/commit-msg $ chmod +x .git/hooks/commit-msg
The hook will now be executed whenever you create or change a new commit message. If the sentiment of the message is considered too negative, the commit will be aborted. This is how an interaction may look like:
$ touch Foo $ git add Foo $ git commit -m "Your code is crap and you are dumb" This commit seems to be written very negatively. You might want to overthink it and rewrite it. If you are really, really sure, use git commit --no-verify to skip this check. $ git commit -m "Your code is okayish and you are not completely stupid" [master 0c97888] Your code is okayish and you are not completely stupid 1 file changed, 0 insertions(+), 0 deletions(-) create mode 100644 Foo
The hook requires a working installation of the cool AFINN sentiment analysis library. Thanks for Finn Årup Nielsen for providing it!
Known issues & disclaimer
The hook cannot detect sarcasm. Also, cleverly-worded insults will not be understood either. This is obviously provided as a tongue-in-cheek script—above all, do no harm to your fellow developers.
