The year is 2006. You’ve just followed some guy’s “how to make a blog” tutorial and you love this new framework. You’ve also just read some famous and snarky Stack Overflow posts about regular expressions.

You want to contribute somehow to this exciting new tech stack. Aha! An email validator that doesn’t rely on regexps!

So, you type svnadmin create validates_email_format_of and away you go.

Rails' old welcome screen

Since I first wrote validates_email_format_of it’s been maintained by a variety of people. And as of 2023 it’s found its way back to me.
