RETURN global variable
Introduction
Codea's in-app reference documents the BACKSPACE
global variable. The use of the undocumented RETURN
global variable is similar. RETURN
is built-in to refer to a string that can be compared with the value referenced by key
in keyboard(key)
when the 'return' key is pressed. For example:
function keyboard(key)
-- Did the user press the return key?
if key == RETURN then
-- Do something
end
end
Value referenced by RETURN
The value referenced by RETURN
is "\n"
, a string containing only a carriage return character. For example:
print(RETURN == "\n") -- Outputs: true
