Go Naming: Why Getters Drop the Get Prefix (and Other Idioms)

Muscle memory from Java, C#, or PHP takes over, and you type GetName() . The code compiles. Tests pass. Then a reviewer leaves a comment that just says "drop the Get" with no explanation, and you're left wondering whether that's a real rule or one person's taste. It's a real rule. It's written into the language's own style guide, the standard library follows it everywhere, and several linters will flag the code that breaks it. Go naming isn't a matter of opinion the way it is in some languages. A handful of conventions are baked into the tooling, and once you know them, half the reviewer nitpicks disappear. Getters drop the Get The convention comes straight from the Effective Go document. If you have an unexported field owner , the accessor is named Owner , not GetName or GetOwner . The mutator, if you need one, keeps the Set prefix. type File struct { owner string } func ( f * File ) Owner () string { return f . owner } func ( f * File ) SetOwner ( o string ) { f . owner = o } The reasoning is about how the call reads. person.Name() says the same thing as GetName() with less noise, and the parentheses already tell you it's a method call. Get adds a word that carries no information in a language where field access and method calls look different anyway. The Set prefix stays because there's no other clean way to signal mutation. Name() reads, SetName(x) writes. The asymmetry is deliberate. This shows up all over the standard library. bytes.Buffer has Len() , not GetLen() . sync.Once has no getters to get wrong, but http.Request exposes fields and methods that never carry a Get . time.Time has Hour() , Minute() , Second() . The pattern is
