Hello! I’m a hobbyist in this space (scripting/coding), does anyone here have a:
- gold standard of what commit messages should look like?
- common practice/etiquette for commit message?
I never had a team or guide or mentor and when I saw this i felt that my commits are like smoke signals describing that there’s a fire. which isnt really helpful.
I tried to contribute to a python module that I use daily, my PR was so over engineered (iirc i added just 3 lines, but with tests, screenshots, CI/CD) i think to compensate for my lack of experience that I got called out (“wow this is pretty extreme just for that feature”).
My personal cent: Some tools strongly suggest that your commit messages should not exceed 50 characters in the first line, and 80 characters on every other line. While the 80-character rule makes sense if you’re using a terminal (and someone on your team will even if you don’t), I strongly disagree with the 50-character rule. If you want to be in any way clear what you did, 50 characters is simply not enough even for the subject line.
The reason for the approximately 50 character limit is because there’s many tools that display a single line and will truncate it if it’s more than about that length (though really the point of truncation can vary wildly – plenty of tools will let you go twice that before they cut you off). So if your one line summary is too long, it’ll be cut off and harder to understand your commit at a glance.
You always can elaborate in a second paragraph, at any rate.
How much can you really put in 50 characters?
Fix: NPE in customer download component when users – That’s 50 characters. Should I not mention where I fixed the bug?
Fix: NPE when users downloaded customers without s – I think I can get rid of the actor in some cases.
̀ Fix: NPE when downloading customers without select`. The summary I want to give cannot be truncated any further.
Fix: NPE when downloading customers. This fits, but is so vague as to be pointless as a summary, in my view.
We’re lucky in that the inventors of our technology are still alive (for the most part). So we can ask them: Linus Torvalds on git commit messages
And I still end up doing it wrong
Hot take: Even these ‘useless’ comments help, since they relieve you of the burden of reading the code itself, even if it’s trivial. One line of English is easier to parse than one line of trivial code.
Yep.
But reading one outdated line of English is worse than reading 5 lines of code and seeing the true picture.
