template<unsigned size_> args (int &argc, char **&argv, option(&o)[size_], int min_args, int max_args, Glib::ustring const &description)

Parse the commandline providing a list of possible options. unsigned size () const

The number of non-option arguments. std::string const & operator[] (unsigned idx) const

Get the non-option arguments. std::vector< std::string >

::const_iterator begin () const "

Iterate over the non-option arguments. std::vector< std::string >

::const_iterator end () const "

Iterate over the non-option arguments.

Commandline and configuration file parsing helper.

Args is a commandline parsing helper. It allows giving the possible short and long options in a simple list and provides --help and --version output to the user of the program.

Usage: create an array of shevek::args::option, containing the desired options. create an instance of args and pass it argc and argv on the constructor. It will call all the callbacks of the options from the constructor. size () and operator[] can be used to access the non-option arguments.

Parse the commandline. Only the default arguments (--help, -h and --version) are understood.
