Detailed Description

An example of performing regex match and regex replace with std::wstring and std::u16string.

 
#include <iostream>
#include "jpcre2.hpp"
#include <sstream>
 
typedef jpcre2::select<wchar_t> jpw; //for windows it's 16
#if __cplusplus >= 201103L
typedef jpcre2::select<char16_t> jpu; //sizeof(char16_t)*CHAR_BIT will be taken as default value for BS
#endif
 
int main() {
    
    //Working with wchar_t i.e std::wstring
    //In Linux this will require 32-bit library to be linked, because, wchar_t is 32 bit in Linux.
    //Match:
    std::cout<<"\n"<<
    jpw::Regex(L"[\\w]+").match(L"I am a subject with 7 matches", "g"); //modifier is always std::string
    
    //Replace
    std::wcout<<L"\n"<<
    jpw::Regex(L"subject").replace(L"I am a subject",L"string (got replaced)"); 
    
    
    #if __cplusplus >= 201103L
    //Working with char16_t i.e std::u16string (>=C++11)
    
    //Match:
    std::cout<<"\n"<<
    jpu::Regex(u"[\\w]+").match(u"I am a subject with 7 matches", "g"); //modifier is always std::string
    
    //Replace
    std::u16string us = jpu::Regex(u"subject").replace(u"I am a subject", u"string (got replaced)");
    std::wcout<<L"\n"<<std::wstring(us.begin(), us.end()); //naive conversion, will work for this example.
    #endif
    
    return 0;
