Text.Pandoc.MediaBag

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

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 MediaBags.

Monoid MediaBag

Methods

mempty :: MediaBag

mappend :: MediaBag -> MediaBag -> MediaBag

mconcat :: [MediaBag] -> MediaBag

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.
