Description

Definition of a MediaBag object to hold binary resources, and an interface for interacting with it.

Synopsis

- data MediaBag
- lookupMedia :: FilePath -> MediaBag -> Maybe (MimeType, ByteString)
- insertMedia :: FilePath -> Maybe MimeType -> ByteString -> MediaBag -> MediaBag
- mediaDirectory :: MediaBag -> [(String, MimeType, Int)]
- extractMediaBag :: Bool -> FilePath -> MediaBag -> IO ()

# Documentation

data MediaBag #

A container for a collection of binary resources, with names and mime types. Note that a `MediaBag` is a Monoid, so `mempty` can be used for an empty `MediaBag`, and `<>` can be used to append two `MediaBag`s.

lookupMedia :: FilePath -> MediaBag -> Maybe (MimeType, ByteString) #

Lookup a media item in a `MediaBag`, returning mime type and contents.

insertMedia #

Arguments

:: FilePath | relative path and canonical name of resource
-> Maybe MimeType | mime type (Nothing = determine from extension)
-> ByteString | contents of resource
-> MediaBag |
-> MediaBag |

Insert a media item into a `MediaBag`, replacing any existing value with the same name.

mediaDirectory :: MediaBag -> [(String, MimeType, Int)] #

Get a list of the file paths stored in a `MediaBag`, with their corresponding mime types and the lengths in bytes of the contents.

extractMediaBag :: Bool -> FilePath -> MediaBag -> IO () #

Extract contents of MediaBag to a given directory. Print informational messages if `verbose` is true.
