Description

Parsing of RFC822-style headers (name, value pairs) Partly based on code from WASHMail.

Synopsis

type Header = (String, String) pHeader :: Parser Header pHeaders :: Parser [Header] parseHeaders :: Monad m => SourceName -> String -> m [Header] data ContentType = ContentType { ctType :: String ctSubtype :: String ctParamaters :: [(String, String)] } getContentType :: Monad m => [Header] -> m ContentType parseContentType :: Monad m => String -> m ContentType showContentType :: ContentType -> String data ContentTransferEncoding = ContentTransferEncoding String getContentTransferEncoding :: Monad m => [Header] -> m ContentTransferEncoding parseContentTransferEncoding :: Monad m => String -> m ContentTransferEncoding data ContentDisposition = ContentDisposition String [(String, String)] getContentDisposition :: Monad m => [Header] -> m ContentDisposition parseContentDisposition :: Monad m => String -> m ContentDisposition parseM :: Monad m => Parser a -> SourceName -> String -> m a

Headers

type Header = (String, String)

pHeader :: Parser Header

pHeaders :: Parser [Header]

parseHeaders :: Monad m => SourceName -> String -> m [Header]

Content-type

data ContentType

A MIME media type value. The Show instance is derived automatically. Use showContentType to obtain the standard string representation. See http://www.ietf.org/rfc/rfc2046.txt for more information about MIME media types. Constructors ContentType ctType :: String The top-level media type, the general type of the data. Common examples are "text", "image", "audio", "video", "multipart", and "application". ctSubtype :: String The media subtype, the specific data format. Examples include "plain", "html", "jpeg", "form-data", etc. ctParamaters :: [(String, String)] Media type parameters. On common example is the charset parameter for the "text" top-level type, e.g. ("charset","ISO-8859-1"). Instances Eq ContentType Ord ContentType Read ContentType Show ContentType

getContentType :: Monad m => [Header] -> m ContentType

parseContentType :: Monad m => String -> m ContentType

Parse the standard representation of a content-type. If the input cannot be parsed, this function calls fail with a (hopefully) informative error message.

showContentType :: ContentType -> String

Produce the standard string representation of a content-type, e.g. "text/html; charset=ISO-8859-1".

Content-transfer-encoding

data ContentTransferEncoding

Constructors ContentTransferEncoding String Instances Eq ContentTransferEncoding Ord ContentTransferEncoding Read ContentTransferEncoding Show ContentTransferEncoding

getContentTransferEncoding :: Monad m => [Header] -> m ContentTransferEncoding

parseContentTransferEncoding :: Monad m => String -> m ContentTransferEncoding

Content-disposition

data ContentDisposition

Constructors ContentDisposition String [(String, String)] Instances Eq ContentDisposition Ord ContentDisposition Read ContentDisposition Show ContentDisposition

getContentDisposition :: Monad m => [Header] -> m ContentDisposition

parseContentDisposition :: Monad m => String -> m ContentDisposition

Utilities

parseM :: Monad m => Parser a -> SourceName -> String -> m a
