Classy Prisms

class IsRaw a where Source #

Classy prism into the shell command of a CmdSpec

Methods

_Raw :: Prism' a (FilePath, [String]) Source #

Instances

IsRaw CmdSpec Source #
Instance details Defined in System.Process.Lens.CommandSpec Methods _Raw :: Prism' CmdSpec (FilePath, [String]) Source #

class IsShell a where Source #
