Method Format

xerror/stack.go:121–141

Format of frame formats the frame according to the fmt.Formatter interface. %s source file %d source line %n function name %v equivalent to %s:%d Format accepts flags that alter the printing of some verbs, as follows: %+s function name and path of source file relative to the co

(s fmt.State, verb rune)

//	      GOPATH separated by \n\t (<funcname>\n\t<path>)
//	%+v   equivalent to %+s:%d
func (f frame) Format(s fmt.State, verb rune) {
	switch verb {
	case 's':
		switch {
		case s.Flag('+'):
			_, _ = io.WriteString(s, f.name())
			_, _ = io.WriteString(s, "\n\t")
			_, _ = io.WriteString(s, f.file())
		default:
			_, _ = io.WriteString(s, path.Base(f.file()))
		}
	case 'd':
		_, _ = io.WriteString(s, strconv.Itoa(f.line()))
	case 'n':
		_, _ = io.WriteString(s, funcname(f.name()))
	case 'v':
		f.Format(s, 's')
		_, _ = io.WriteString(s, ":")
		f.Format(s, 'd')

// MarshalText formats a stacktrace Frame as a text string. The output is the
// same as that of fmt.Sprintf("%+v", f), but without newlines or tabs.
