Classes

class HasRaw a where

Classy prism into the shell command of a CmdSpec

Methods

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

Instances

HasRaw CmdSpec

Defined in System.Process.Lens.CommandSpec

Methods

_Raw :: Prism' CmdSpec (FilePath, [String])

class HasShell a where

Classy prism into the shell command of a CmdSpec

Methods

_Shell :: Prism' a String

Instances

HasShell CmdSpec

Defined in System.Process.Lens.CommandSpec

Methods

_Shell :: Prism' CmdSpec String

class HasInherit a where

Class constraint proving a type has a prism into an Inherit structure. In general, this seems redundant, however, this class is a proof on a that a is an Inherit, which is a wonderful thing to prove.

Methods

_Inherits :: Prism' a StdStream

Instances

HasInherit StdStream

Defined in System.Process.Lens.StdStream

Methods

_Inherits :: Prism' StdStream StdStream

class HasUseHandle a where

Class constraint proving a type has a prism into a Handle via a UseHandle structure.

Methods

_UsesHandle :: Prism' a Handle

Instances

HasUseHandle StdStream

Defined in System.Process.Lens.StdStream

Methods

_UsesHandle :: Prism' StdStream Handle

class HasCreatePipe a where

Class constraint proving a type has a prism into a Handle via a UseHandle structure.

Defined in System.Process.Lens.StdStream

Methods

_CreatesPipe :: Prism' StdStream StdStream

class HasNoStream a where

Class constraint proving a type has a prism into a Handle via a UseHandle structure.

Methods

_NoStreams :: Prism' a StdStream

Instances

HasNoStream StdStream

Defined in System.Process.Lens.StdStream

_NoStreams :: Prism' StdStream StdStream

Combinators

stdoutOf :: CreateProcess -> Maybe Handle

Retrieve the stdin handle associated with a CreateProcess

stdinOf :: CreateProcess -> Maybe Handle

Retrieve the stdout handle associated with a CreateProcess

stderrOf :: CreateProcess -> Maybe Handle

Retrieve the stderr handle associated with a CreateProcess

closing :: HasUseHandle a => Getter CreateProcess a -> CreateProcess -> IO ()

Close something with a prism into a non-standard Handle in a CreateProcess

inheriting :: Lens' a StdStream -> a -> a

Given a lens into a StdStream, overwrite to Inherit so that the stream inherits from its parent process

piping :: Lens' a StdStream -> a -> a

Given a lens into a StdStream, overwrite to CreatePipe, piping the process

handling :: Lens' a StdStream -> Handle -> a -> a

Given a lens into a StdStream and a handle, set the handle using UseHandle.

nostreaming :: Lens' a StdStream -> a -> a

Given a lens into a StdStream, set to NoStream

arguing :: String -> CmdSpec -> CmdSpec

Append an argument to the argument list of a RawCommand
