Function SetOptions

sjson.go:631–647

SetOptions sets a json value for the specified path with options. A path is in dot syntax, such as "name.last" or "age". This function expects that the json is well-formed, and does not validate. Invalid json will not panic, but it may return back unexpected results. An error is returned if the path

(json, path string, value interface{},
	opts *Options)

// Invalid json will not panic, but it may return back unexpected results.
// An error is returned if the path is not valid.
func SetOptions(json, path string, value interface{},
	opts *Options) (string, error) {
	if opts != nil {
		if opts.ReplaceInPlace {
			// it's not safe to replace bytes in-place for strings
			// copy the Options and set options.ReplaceInPlace to false.
			nopts := *opts
			opts = &nopts
			opts.ReplaceInPlace = false
