• flags are only ones took over from https://godoc.org/golang.org/x/tools/go/analysis tool. check allcases -help for them.
• package format is based on go tools such as ./... .

Annotation

This checker checks for switch statements which have an annotation comment // allcases to have all cases for consts of the expression type.

For example if there is a type and consts like:

	type TestKind int

	const (
		TestKindHoge TestKind = iota
		TestKindFuga
		TestKindPiyo
	)

and switch statements like:

	// allcases
	switch v {
	case TestKindHoge:
		// do something
	case TestKindFuga:
		// do something
	}

then the checker reports that the switch statement doesn't have the TestKindPiyo case.
