io.input

Syntax

a = io.input(s)

Get input from the current input source. The function behaves just as io.in, except the input may come from either the console or a data file, which ever one is the current input source. If the input source is a data file, the next line of text from the file is read. The return value depends on the characters input. FISH tries to decode the input first as an integer, and then as a floating-point number. The return value will be of these types if the input is a single number that can be decoded with one of these types. In this case, the number should be the only data entered. If the input characters cannot be interpreted as a single number, the return value will be a string of those characters. The functions type and type.name can be used to determine the return type.

Returns:

a - integer, double, or string

Arguments:

s - string printed prior to input from the current input device
