Clipo : Command Line Interpreter library based on the boost Program Option libraryThe idea is to build on top of the program_option library developed by Vladimir Prus (http://www.boost.org/doc/html/program_options.html) an easy to implement command line interpreter library.

Examplenamespace po = boost::program_options;

void handler(const std::vector &parameters) {
for (std::vector::const_iterator it = parameters.begin();
it != parameters.end();
++it)
std::cout << *it << std::endl;
}

void exit_(unsigned int code = 0) {
exit(code);
}

int main(int argc, char **argv) {
boost::cli::commands_description desc;
desc.add_options()
("handler", po::value< std::vector >()->notifier(&handler)->multitoken())
("exit", po::value< unsigned int >()->notifier(&exit_))
;

boost::cli::command_line_interpreter cli(desc, ">");
  cli.interpret(std::cin);
}output:

>handler
error: required parameter is missing in 'handler'
>handler 1 2 3
1
2
3
>toto
error: unknown option toto
>exit 0
