API

..function:: getwidth()

Return width of available window in characters. If detection fails, return value of standard width 80. Coordinate of the last character on a line is -1 from returned value.

..function:: getheight()

Return available window height in characters or 25 if detection fails. Coordinate of the last line is -1 from returned value.

..function:: getch()

Wait for keypress and return character or a list of characters. Arrows and special keys generate a sequence of characters, so if there are extra symbols in input buffer, this function returns list.

..function:: page(content, [pagecallback=prompt])

Output content iterable, calling pagecallback function after each page with page number as a parameter. Default prompt() callback shows page number with ‘Press any key … ‘ prompt and waits for keypress.
