Why? It shouldn't. search() prepares the regexp for use in foreach loop. The correct function for you is find: import std.regexp; import std.stdio; void main() { string someString = "Hello world!"; auto regExp = new RegExp(r"[wW]orld"); auto result = regExp.find(someString); if (result == -1) { writefln("Not found!"); } else { writefln("Result:" ~ regExp[0]); } } | |||||||||||||
