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 :: MonadFail m => SourceName -> String -> m [Header]
data ContentType = ContentType {
- ctType :: String
- ctSubtype :: String
- ctParameters :: [(String, String)]
}
getContentType :: MonadFail m => [Header] -> m ContentType
parseContentType :: MonadFail m => String -> m ContentType
showContentType :: ContentType -> String
data ContentTransferEncoding = ContentTransferEncoding String
getContentTransferEncoding :: MonadFail m => [Header] -> m ContentTransferEncoding
parseContentTransferEncoding :: MonadFail m => String -> m ContentTransferEncoding
data ContentDisposition = ContentDisposition String [(String, String)]
getContentDisposition :: MonadFail m => [Header] -> m ContentDisposition
parseContentDisposition :: MonadFail m => String -> m ContentDisposition
parseM :: MonadFail m => Parser a -> SourceName -> String -> m a

Headers

type Header = (String, String) Source #

pHeader :: Parser Header Source #

pHeaders :: Parser [Header] Source #

parseHeaders :: MonadFail m => SourceName -> String -> m [Header] Source #

Content-type

data ContentType Source #

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

Fields

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.
ctParameters :: [(String, String)]
Media type parameters. On common example is the charset parameter for the "text" top-level type, e.g. ("charset","ISO-8859-1").

getContentType :: MonadFail m => [Header] -> m ContentType Source #

parseContentType :: MonadFail m => String -> m ContentType Source #

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 Source #

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