Contexts
karma has contexts support, which allows to add arbitrary key-value fields to the error to ease debug.
Simplest usage is to add key-values for existing error:
func bar(arg string) error {
return fmt.Errorf("arg is invalid: %s", arg)
}
func foo(arg string) error {
err := bar(arg)
if err != nil {
return karma.Describe("method", "bar").Reason(err)
}
}
fmt.Println(foo("hello"))
// Output:
//
// arg is invalid: hello
// └─ method: barComparison
