check-deprecated

check-deprecated is a Go static analysis tool.

It finds malformed deprecated comments, and finds the use of deprecated function/variable/constant/field

Purpose

We need an analyzer that checks deprecated usage. But as this issue says,

Actually it looks like staticcheck does have an appropriate check (SA1019) but for whatever reason it doesn't seem to work. Might open a separate issue to discuss that.

And I think SA1019 is too strict about the deprecated comments, so that some situations cannot be detected.

We use a very loose detection patterns, you can even customize it.

patterns := []string{"MyDeprecated: "}

// MyDeprecated: don't use it.
func AFunc()  {}

Of course, standard comments are always popular, so this repo also provides an analysis to detect malformed deprecated comments.
