asciiArt

String of an ASCII artwork to be vectorised

Returns

std::vector<std::string>

enableVirtualTerminal()

bool enableVirtualTerminal

(

)

isValidDeckFileName()

bool isValidDeckFileName

(

const std::string &

name

)

Checks if name for deckfile meets naming requirements.

Deck filenames should only contain [A-Za-z0-9] characters

Parameters

name

Returns

	)

Determines if the number of seconds has elapased since a start time.

Parameters

start_time	the time to count number of seconds from
duration_secs	time period to check has elapsed

Returns

timeRemainingMins()

int timeRemainingMins	(	const std::chrono::time_point< std::chrono::steady_clock > &	start_time,
		const int &	duration_mins
	)

Used to display the time remaining to users. To determine the actual end the session use timeComplete()

Parameters
