Command Line Interface

The command arguments are passed to main. Since the char*[] type is unflexible, we convert it to an arglist object which is a copy of argv. The first element is removed because it is just the name of the executable.

typedef std::vector<std::string> arglist

typedef std::vector<std::string>::iterator arglist_iter

Next we check if the program should run in GUI mode, i.e. if the --gui option was specified. In that case, we call the function start_gui which takes control of the program.

If we are in CLI mode, the program runs the command whose name is specified as the second argument by calling execute_command:

int execute_command(const arglist_iter &it_arg, const arglist_iter &end)

Execute a command, or print a message if it does not exist.

Return

Status code of the executed command.

Parameters

• it_arg: Iterator to the first argument in the list.

• end: - End of the argument list

All defined commands are part of a std::map called commands that maps each command name to a function.
