noncapturing

Not capturing.

Another type of rider is the Mao which is the knight in Chinese chess. It makes its move in two steps, a noncapturing wazir move followed by a fers move, so the cell moved through must be vacant. The Moa (W.Speckman) is a knight that moves as fers followed by wazir.

That does not store its matched text for later processing.

Noncapturing groups can be used to describe repetition patterns or alternatives, without isolating the matching portion of the string in the value returned.
