您如何在Go中将代码标记为已弃用？

Question

In Go, how do you mark code as deprecated so that users get a warning when using it?

Answer 1

You could create a package named old/yourpackage and advise using it if someone relies on deprecated functionality/interfaces and then create an updated package yourpackage without the old stuff.

There's no way to insert either warnings or marking methods as deprecated in other way than in documentation, as per Godoc: documenting Go code blog post which says:

To signal that an identifier should not be used, add a paragraph to its doc comment that begins with "Deprecated:" followed by some information about the deprecation. There are a few examples in the standard library.
