将符号定义为UserID还是UserId？

Question

In Go I've seen some people defining symbols (methods, variables, etc) like this: UserID, GetSomeURL() with UPPERCASE letters of ids, urls, etc.

Is this a standard way?

Even my editor, that uses go-lint, warns me that I should change it (because I use UserId).

I read some of the golang source code https://golang.org/src/ and I never saw some like UserID.

Is this going to be another "tabs" vs "spaces" thing? LOL

I know this does not cause any problems compiling or any other problem, but I'm just trying get some "standard" on this.

Answer 1

UserID and GetSomeURL (or simply SomeULR()) would be idiomatic.

Source: https://github.com/golang/go/wiki/CodeReviewComments#initialisms:

Words in names that are initialisms or acronyms (e.g. "URL" or "NATO") have a consistent case. For example, "URL" should appear as "URL" or "url" (as in "urlPony", or "URLPony"), never as "Url". Here's an example: ServeHTTP not ServeHttp.

This rule also applies to "ID" when it is short for "identifier," so write "appID" instead of "appId".

You are right, golint is useful to identify deviations from the standard naming convention - it's good to follow its advices (especially when the code is worked on by multiple people and coding style consistency is even more valuable).
