10.3.3 Replace

A regular expression can also be used to replace a part of the string:

class Main {
  static function main() {
    var str = "aaabcbcbcbz";
    // g : replace all instances
    var r = ~/b[^c]/g;
    // "aaabcbcbcxx"
    trace(r.replace(str, "xx"));
  }
}

We can use $X to reuse a matched group in the replacement:

class Main {
  static function main() {
    var str = "{hello} {0} {again}";
    var r = ~/{([a-z]+)}/g;
    // "*hello* {0} *again*"
    trace(r.replace(str, "*$1*"));
  }
}
