A prism into the ShellCommand case of a CmdSpec

Examples:

>>> _ShellCommand # "ls -l"
ShellCommand "ls -l"

>>> ShellCommand "ls -l" ^? _ShellCommand
Just "ls -l"

>>> RawCommand "/bin/ls" ["-l"] ^? _ShellCommand
Nothing

A prism into the RawCommand case of a CmdSpec

Examples:

>>> RawCommand "/bin/ls" ["-l"] ^? _RawCommand
Just ("/bin/ls",["-l"])

>>> RawCommand "/bin/ls" ["-l"] ^? _ShellCommand
Nothing

>>> RawCommand "/bin/ls" ["-l"] ^. _RawCommand . _1
"/bin/ls"

>>> RawCommand "/bin/ls" ["-l"] ^. _RawCommand . _2
["-l"]

A Prism' into the Inherit structure of a StdStream

Examples:

>>> _Inherit # ()
Inherit

A Prism' into the UseHandle structure's Handle for a StdStream

Examples:

>>> _UseHandle # System.stdin
UseHandle {handle: <stdin>}

A Prism' into the CreatePipe structure of a StdStream

Examples:

>>> _CreatePipe # ()
CreatePipe

A prism into the NoStream structure of a StdStream

Examples:

>>> _NoStream # ()
NoStream

An iso between the ProcessHandler data and its product representation

Traversal' into the arguments of a command

Examples:

>>> RawCommand "/bin/ls" ["-l"] ^. arguments
["-l"]

Classy prism into the raw command of a CmdSpec

Examples:

>>> f :: AsRaw a => a -> Maybe FilePath; f = preview (_Raw . _1)
>>> f $ _RawCommand # ("/bin/ls", ["ls -l"])
Just "/bin/ls"

Classy prism into the shell command of a CmdSpec

Examples:

>>> f :: AsShell a => a -> Maybe String; f = preview _Shell
>>> f $ _ShellCommand # "ls -l"
Just "ls -l"

Class constraint proving a type has a prism into an Inherit structure. Any StdStream will have a prism into Inherit - it is just an overwrite to Inherit

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

Class constraint proving a type has a prism into a Handle via a UseHandle structure. Any StdStream will have a prism into CreatePipe - it is just an overwrite to CreatePipe

Class constraint proving a type has a prism into a Handle via a UseHandle structure. Any StdStream will have a prism into NoStream - it is just an overwrite to NoStream.
