With reference to boost 1.59 and program options.
The following test passes on boost 1.53, but fails on boost 1.59.
I need to able to handle.
--arg1 10 and
--arg1=10
boost 1.59 now fails on '--arg1 10', with test below with option value
being empty.
#include <string>
#include <iostream>
#include <fstream>
#include
#include
#include
using namespace std;
namespace po = boost::program_options;
BOOST_AUTO_TEST_SUITE( BaseTestSuite )
BOOST_AUTO_TEST_CASE( test_program_options_implicit_value )
{
cout << "Base:: ...test_program_options_implicit_value\n";
// Declare the supported options.
po::options_description desc("Allowed options");
desc.add_options()
("help", "produce help message")
("arg1", po::value<string>()->implicit_value( string("") ),
"optional arg1 description") ;
{
char* argv[] = {
const_cast("test_program_options_implicit_value"),
const_cast("--help"),
const_cast("--arg1")
};
po::variables_map vm;
po::store(po::parse_command_line(3, argv, desc), vm);
po::notify(vm);
BOOST_CHECK_MESSAGE(vm.count("help"), "Expected help");
BOOST_CHECK_MESSAGE(vm.count("arg1"), "Expected arg1");
BOOST_CHECK_MESSAGE(vm["arg1"].as<string>() == "", "Expected arg1 to
be empty");
}
{
// ****** This fails on boost 1.59 bit passes in boost 1.53 *******
char* argv[] = {
const_cast("test_program_options_implicit_value"),
const_cast("--arg1"),
const_cast("10")
};
po::variables_map vm;
po::store(po::command_line_parser(3, argv, desc), vm);
po::notify(vm);
BOOST_CHECK_MESSAGE(vm.count("arg1"), "Expected arg1");
BOOST_CHECK_MESSAGE(vm["arg1"].as<string>() == "10",
"Expected arg1 with value of 10 but found '" <<
vm["arg1"].as<string>() << "'");
}
{
char* argv[] = {
const_cast("test_program_options_implicit_value"),
const_cast("--arg1=11")
};
po::variables_map vm;
po::store(po::parse_command_line(2, argv, desc), vm);
po::notify(vm);
BOOST_CHECK_MESSAGE(vm.count("arg1"), "Expected arg1");
BOOST_CHECK_MESSAGE(vm["arg1"].as<string>() == "11",
"Expected arg1 with value of 11 but found " <<
vm["arg1"].as<string>());
}
}
