Notes while factoring code and verifying things.

Updating all dependencies for a module

Helpful for dusting a project off.

$ go get -u ./...
$ go mod tidy
$ go test ./... # good idea to ensure new deps did not break things
Golang Doc: Deprecating things

Godoc can note deprecation. JetBrains projects pickup and note these in the IDE. Example:

//Filter returns a subset of elements for each test which is true
//Deprecated: use golang.org/x/exp instead.
func Filter[E any](elements []E, test func(e E) bool) []E {
	out := make([]E, 0)
	for _, e := range elements {
		if test(e) {
			out = append(out, e)
		}
	}
	return out
}
