XMonad.Util.Invisible

Contents

Description

A data type to store the layout state

Synopsis

Usage:

A wrapper data type to store layout state that shouldn't be persisted across restarts. A common wrapped type to use is Maybe a. Invisible derives trivial definitions for Read and Show, so the wrapped data type need not do so.
