parseArguments()

bool parseArguments	(	int	argc,
		char *	argv[],
		Config &	config,
		std::string &	error )

Reads command-line options into a Config.

Running with no options (or only –no-color) turns on interactive mode so the user is asked for the main settings.

Parameters

argc	Argument count from main().
argv	Argument values from main().
config	Receives the parsed settings.
error	Receives a message when parsing fails.

Returns

False if an option is unknown or a value is malformed.

promptForSettings()

void promptForSettings	(	Config &	config,
		std::istream &	in,
		std::ostream &	out )

Asks the user for the main settings, keeping the current value when the answer is blank.

Parameters

config	Settings to update.
in	Stream to read answers from.
out	Stream to write questions to.

Definition at line 201 of file Config.cpp.

validateConfig()

bool validateConfig	(	const Config &	config,
		std::string &	error )

Checks that the settings are consistent.

Parameters

config	Settings to check.
error	Receives a message describing the first problem found.

Returns

True if the settings can be simulated.
