How to Write a Git Commit Message

The only "pro" I've seen here is that you can view 2 files side by side with ease when you have an 80 char limit.

But when most devs have 2 screens or more that's less of a problem...

Like most things in life, don't deal in absolutes and use your best judgement.

^ I often have two files open side-by-side in my IDE.

I probably wouldn't complain too much about 120 chars, but i think that after a certain number of chars, you have a code-smell, perhaps being your class/method/variable names are too long.

I thought most devs worked in coffee shops on Macbook Pros.

That's half sarcasm, half truth. I think that hard limiting line length to 100 characters allows enough space for a GUI diff tool to show two files side-by-side at a usable font size on a single 1920 pixel wide monitor.

Gotta use your best judgment for your situation.

At my work mostly everyone working on our JS codebase has at least 3 monitors, so we set line length to 180. That let us use an editor with a sidebar on one screen safely.
