import std.stdio, std.regexp;

void main() {

string s = "I am a string";

// Test:

if (search(s, r"string$"))

writefln("Ends with 'string'");

// Test, storing the regular expression:

auto re1 = RegExp(r"string$");

if (re1.search(s).test)

writefln("Ends with 'string'");

// Substitute:

writefln(sub(s, " a ", " another "));

// Substitute, storing the regular expression:

auto re2 = RegExp(" a ");

writefln(re2.replace(s, " another "));

}

Note that in std.string there are string functions to perform those string operations in a faster way.
