directoryPath : Path Directory
filePath : Path File
encapsulatedPath : Path Encapsulated
type Directory

👻 Directory

type File

👻 File

type Encapsulated

👻 Encapsulated

type Kind

| File

Creation

directory : Array String -> Path Directory

Create a directory path.

directory [ "Audio", "Playlists" ]
file : Array String -> Path File

Create a file path.

file [ "Document", "invoice.pdf" ]

POSIX

fromPosix : String -> Path Encapsulated

Convert a POSIX formatted string to a path. This will return a Encapsulated path. To get a path of the type Path Directory or Path File, use the functions in the Shikensu.Path.Encapsulated module.

>>> import Shikensu.Path.Encapsulated
>>> "foo/bar/"
..>   |> fromPosix
..>   |> Shikensu.Path.Encapsulated.toDirectory
Just (directory [ "foo", "bar" ])

>>> "foo/bar"
..>   |> fromPosix
..>   |> Shikensu.Path.Encapsulated.toFile
Just (file [ "foo", "bar" ])
toPosix : { absolute : Bool } -> Path kind -> String

Convert a path to the POSIX format.

>>> toPosix { absolute = True } (directory [ "foo", "bar"])
"/foo/bar/"
>>> toPosix { absolute = False } (file [ "foo", "bar"])
"foo/bar"

Encapsulation

encapsulate : Path kind -> Path Encapsulated

Encapsulate a path.

Functions

combine : Path Directory -> Path kind -> Path kind

Combine a directory path and another path.

kind : Path kind -> Kind

Get the path kind.

>>> kind (directory [])
Directory
>>> kind (file [])
File

Even if a path is encapsulated, you can still check the kind of path it is.

>>> kind (encapsulate <| directory [])
Directory
>>> kind (encapsulate <| file [])
File
length : Path kind -> Int

Length.

map : (Array String -> Array String) -> Path kind -> Path kind

Map.

unwrap : Path kind -> Array String

Get the path parts.

>>> unwrap (directory [ "foo", "bar" ])
[ "foo", "bar" ]
>>> unwrap (file [ "foo", "bar" ])
[ "foo", "bar" ]
