The Effects Tutorial

A tutorial on the Effects package in Idris.

Effects and the Control.ST module

There is a new module in the contrib package, Control.ST, which provides the resource tracking facilities of Effects but with better support for creating and deleting resources, and implementing resources in terms of other resources.

Unless you have a particular reason to use Effects you are strongly recommended to use Control.ST instead. There is a tutorial available on this site for Control.ST with several examples (Implementing State-aware Systems in Idris: The ST Tutorial).
