var PrettyIndent = ""

PrettyIndent sets the indentation used to pretty-print JSON and XML body files, when these are written (see WithHeadersAndBodies and LongBodyThreshold). When non-blank, PrettyIndent

var WriteJSONFile = func(out io.Writer, body []byte) error {
	if len(PrettyIndent) == 0 {
		return writePlainText(out, body)
	}

	var data interface{}
	err := json.NewDecoder(bytes.NewReader(body)).Decode(&data)
	if err != nil {
		return writePlainText(out, body)
	}

	var enc = json.NewEncoder(out)
	enc.SetIndent("", PrettyIndent)
	return enc.Encode(data)
}

WriteJSONFile is a function to write JSON files. If PrettyIndent is non-blank, the result is pretty-printed JSON; otherwise, it is verbatim.

An alternative function may be substituted if required.

var WriteXMLFile = func(out io.Writer, body []byte) error {
	if len(PrettyIndent) == 0 {
		return writePlainText(out, body)
	}

	xml := xmlfmt.FormatXML(string(body), "", PrettyIndent)
	if strings.HasPrefix(xml, xmlfmt.NL) {
		xml = xml[len(xmlfmt.NL):]
	}
	_, err := strings.NewReader(xml).WriteTo(out)
	return err
}

WriteXMLFile is a function to write XML files. If PrettyIndent is non-blank, the result is pretty-printed XML; otherwise, it is verbatim.

An alternative function may be substituted if required.
