Hackage Build Status

This package is intended to be minimalistic, with few dependencies aside from lens. For full disclosure, this is the minimal dependency graph of lens-process:

lens-process dependencies


lens-process provides optics for the process package. These optics provide convenient lenses, traversals, and prisms, as well as classy variants for significant classifiable portions of the library for convenience. In addition, we provide some combinators for working with CreateProcess types. The intention of this package is to create a well-typed optical layer for process, reflecting the shape of certain types of commands at the type level.
