Quasi parallel reply to your other post, this would kind of echo the want for a capital letter at the start of the commit message. Icon indicates overall topic nature of commits.
Lets say I am adding a database migration and my commit is the migration file and the schema. My commit message might be:
<span style="color:#323232;"> 🗃️ Add notes to Users table
</span>
So anyone looking at the eventual pr will see the icon and know that this bunch of work will affect db without all that tedious “reading the code” part of the review, or for team members who didn’t participate in reviews.
I was initially hesitant to adopt it but I have very reasonable, younger team mates for whom emojis are part of the standard vocabulary. I gradually came to appreciate and value the ability to convey more context in my commits this way. I’m still guilty of the occasionally overusing:
<span style="color:#323232;"> ♻️ Fix the thing
</span>
type messages when I’m lazy; doesn’t fix that bad habit, but I’m generally much happier reading mine or someone else’s PR commit summary with this extra bit of context added.
