I'm a bit confused about how this works. Can you just use markup like :zap: in a commit message, and GitHub will automatically replace it with an emoji? Or do you need to use some client-side scripts to handle that?
Cool! Is there a method to which gitmoji you use, or is it just random? I could see it as being kinda useful as a way to describe what kind of changes the commit it making.
It seems to be a classification of sorts. He's using {guy running} for performance optimizations like ae65f95, {paint palette} for visual changes, etc. What a neat idea! It's easy to glance at the commit log and get a sense of what the changes are doing.
EDIT: Whoops, the emojis aren't rendering in HN comments. Changed to textual descriptions...
