Description

Minimal set of imports needed to support basic CodeWorld syntax. Many of these are not directly used by students, but are needed for desugaring with the RebindableSyntax extension.

Synopsis

type Program = IO ()
data Number
data Text
type Truth = Bool
data Bool
- = False
- | True
fromInteger :: Integer -> Number
fromRational :: Rational -> Number
fromString :: String -> Text
ifThenElse :: Truth -> a -> a -> a
fail :: HasCallStack => String -> a

Documentation

type Program = IO () #

A computer program.

This is a specific task or application that a computer performs. In CodeWorld, programs are defined using one of the "entry point" functions, such as drawingOf, animationOf, or activityOf.

data Number #

The type for numbers.

Numbers can be positive or negative, whole or fractional. For example, 5, 3.2, and -10 are all values of the type Number.

fromInteger :: Integer -> Number #

fromRational :: Rational -> Number #

fromString :: String -> Text #

ifThenElse :: Truth -> a -> a -> a #

fail :: HasCallStack => String -> a #

Fails with an error message. This is required (though apparently unused) by the desugaring for pattern binds in list comprehensions.
