operator<<,>>(std::filesystem::path)

template< class CharT, class Traits >
std::basic_ostream<CharT,Traits>&
    operator<<( std::basic_ostream<CharT,Traits>& os, const std::filesystem::path& p );

template< class CharT, class Traits >
std::basic_istream<CharT,Traits>&
    operator>>( std::basic_istream<CharT,Traits>& is, std::filesystem::path& p );

Performs stream input or output on the path p. std::quoted is used so that spaces do not cause truncation when later read by stream input operator.

These function templates are not visible to ordinary unqualified or qualified lookup , and can only be found by argument-dependent lookup when std::filesystem::path is an associated class of the arguments. This prevents undesirable conversions in the presence of a using namespace std::filesystem; using-directive.

Parameters

Return value

Exceptions

(none).

Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

Possible implementation

template< class CharT, class Traits >
std::basic_ostream<CharT,Traits>&
    operator<<( std::basic_ostream<CharT,Traits>& os, const path& p )
{
    os << std::quoted(p.string<CharT,Traits>());
    return os;
}

template< class CharT, class Traits >
std::basic_istream<CharT,Traits>&
    operator>>( std::basic_istream<CharT,Traits>& is, path& p )
{
    std::basic_string<CharT, Traits> t;
    is >> std::quoted(t);
    p = t;
    return is;
}

Example

#include <iostream>
#include <filesystem>
int main()
{
        std::cout << std::filesystem::current_path() << '\n';
}
