go-ternary

Yes, I know—yet another attempt at bringing a ternary-like experience to Go. But hey, Go doesn’t have one, and I wasn’t around when the last million were written.

Why?

Because Go doesn't have a ternary operator, and according to the official FAQ, it likely never will. The reasoning? To prevent developers from writing "impenetrably complex expressions." But let's be real—poor coding practices exist in all forms. Instead of outright banning a useful construct, wouldn’t compiler warnings for overly complicated ternary expressions have been a more reasonable approach?

Since that's not happening, here’s go-ternary—because sometimes, a one-liner is just nicer than an if-else.

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.

Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.
