exports

This what you wanted? To be a janitor? Live like this? All this? Do what you do? It can’t be. It’s a burden, that’s what I’m trying to tell you. That’s how it feels.

Michael Clayton (2007)

what

The exports module prints exported identifiers in Go source code.

why

Starting with StaticCheck 2020.2, whole-program mode was removed. it now operates like this:

The normal mode of 'unused' now considers all exported package-level identifiers as used

So we need to unexport all symbols using some tactic. This will then give us agency. StaticCheck will then report symbols as unused, which we can respond to by either exporting them or removing them.

how

If you use a command line this:

gofmt -w -r 'NewBuffer -> _NewBuffer' .

It will also catch imported functions like bytes.NewBuffer. You could try to fix like this:

gofmt -w -r 'a._NewBuffer -> a.NewBuffer' .

but it will also catch method calls:

hello.Len()

we could try hardcoding the exceptions:

gofmt -w -r 'bytes._NewBuffer -> bytes.NewBuffer' .

but the imported method calls will still be broken:

bytes.Buffer._Len()

we can use this:

rf 'mv FinishedHash _FinishedHash'

but it only works for a single identifier. Can we print out all identifiers?
