Nile is a declarative stream-processing language designed to implement graphics-compositing toolkits like wikipedia:Cairo (graphics) with a minimum of code. While not strictly a golfing language, Nile was developed as part of the STEPS project at VPRI, which focused on implementing an operating system using relatively little code and relatively many languages.

Examples

The following program implements the syntax `x ~ y` for computing the average of two numbers:

(a : Real) ~ (b : Real) : Real
    (a + b) / 2
