Text.Pandoc.MediaBag
Description
Definition of a MediaBag object to hold binary resources, and an interface for interacting with it.
Synopsis
- data MediaBag
- deleteMedia :: FilePath -> MediaBag -> MediaBag
- lookupMedia :: FilePath -> MediaBag -> Maybe (MimeType, ByteString)
- insertMedia :: FilePath -> Maybe MimeType -> ByteString -> MediaBag -> MediaBag
- mediaDirectory :: MediaBag -> [(String, MimeType, Int)]
- mediaItems :: MediaBag -> [(String, MimeType, ByteString)]
Documentation
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.

Delete a media item from a MediaBag
, or do nothing if no item corresponds
to the given path.
lookupMedia :: FilePath -> MediaBag -> Maybe (MimeType, ByteString) Source #
Lookup a media item in a MediaBag
, returning mime type and contents.
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)] Source #
Get a list of the file paths stored in a MediaBag
, with
their corresponding mime types and the lengths in bytes of the contents.
mediaItems :: MediaBag -> [(String, MimeType, ByteString)] Source #
