Example usage
============================
Read from archive
```C++
#include "archive_reader.hpp"
#include "archive_exception.hpp"
namespace ar = ns_archive::ns_reader;
std::fstream fs( "some_tar_file.tar" );
ns_archive::reader reader = ns_archive::reader::make_reader<ar::format::_ALL, ar::filter::_ALL>(fs, 1024);
...
for(auto entry : reader)
try
{
namespace ar = ns_archive::ns_reader;
std::fstream fs("some_tar_file.tar");
ns_archive::reader reader = ns_archive::reader::make_reader<ar::format::_ALL, ar::filter::_ALL>(fs, 10240);
for(auto entry : reader)
{
// get file name
std::cout << entry->get_header_value<ns_archive::ns_reader::entry::string_value::PATHNAME>() << std::endl;
std::cout << entry->get_header_value_pathname() << std::endl;
// get file content
std::cout << entry->get_entry_content_stream().rdbuf() << std::endl << std::endl;
std::cout << entry->get_stream().rdbuf() << std::endl << std::endl;
}
}
catch(ns_archive::archive_exception& e)
{
std::cout << e.what() << std::endl;
}
```
Write to archive
```C++
#include "archive_writer.hpp"
#include "archive_exception.hpp"
...
try
{
namespace ar = ns_archive::ns_reader;
std::ofstream outfs("output.tar");
ns_archive::writer writer2 = ns_archive::writer::make_writer<ns_archive::ns_writer::format::_TAR>(outfs, 10240);
std::stringstream ss;
ss << "foo";
ns_archive::entry out_entry(ss);
out_entry.set_header_value_pathname("foo.txt");
writer.add_entry(out_entry);
}
catch(ns_archive::archive_exception& e)
{
std::cout << e.what() << std::endl;
}
```
Copy archive
```C++
#include "archive_reader.hpp"
#include "archive_writer.hpp"
#include "archive_exception.hpp"
...
try
{
namespace ar = ns_archive::ns_reader;
std::fstream fs( "some_tar_file.tar" );
ns_archive::reader reader = ns_archive::reader::make_reader<ar::format::_ALL, ar::filter::_ALL>(fs, 10240);
std::ofstream outfs( "out.tar" );
ns_archive::writer writer = ns_archive::writer::make_writer<ns_archive::ns_writer::format::_TAR>(outfs, 10240);
for(auto entry : reader)
{
writer.add_entry(*entry.get());
}
}
catch(ns_archive::archive_exception& e)
{
std::cout << e.what() << std::endl;
}
```
