This page describes how to use random (to produce pseudo-random values) in ConTeXt and MetaPost. The uniformdeviate function in MetaPost, by default, uses a seeded value. This is useful to generate the "same" random results each time the final product is generated, but hampers creating books that differ from each other on successive generations.
A number of related commands include:
- \getrandomnumber - Generates a pseudo-random number each time.
- \ctxlua{math.randomseed(os.time())} - Sets the seed based on the computer's timestamp.
