Detailed Description

An example of performing regex match and regex replace with std::wstring and std::u32string.

#include <iostream>
#include "jpcre2.hpp"
#if __cplusplus >= 201103L
int main() {
//Working with wchar_t i.e std::wstring
//In Windows this will require 16-bit library to be linked, because wchar_t in windows is 16-bit
jpw::Regex(L"[\\w]+").match(L"I am a subject with 7 matches", "g"); //modifier is always std::string
jpw::Regex(L"subject").replace(L"I am a subject",L"string");
#if __cplusplus >= 201103L
//Working with char32_t i.e std::u32string (>=C++11)
jpu::Regex(U"[\\w]+").match(U"I am a subject with 7 matches", "g"); //modifier is always std::string
std::u32string us = jpu::Regex(U"subject").replace(U"I am a subject",U"string");
std::wcout<<L"\n"<<std::wstring(us.begin(), us.end()); //naive conversion, may fail on windows for string with surrogates.
