http, json, attoparsec and pipes material for streaming
and streaming-bytestring
Streaming.Pipes
reimplements some of the standard pipes splitting and joining operations with Stream
in place of FreeT
. The operations are all plain functions, not lenses. They will thus be simpler to use, unless of course you are using pipes' StateT
parsing. Another module is planned to recover this style of parsing.
Data.ByteString.Streaming.HTTP
just replicates Pipes.HTTP
(barely a character is changed) so that the response takes the form of a ByteString m ()
rather than Producer ByteString m ()
. Something like this is the intuitively correct response type, insofar as a pipes Producer (like a conduit Source and an io-streams InputStream) is properly a succession of independent semantically significant values.
Data.ByteString.Streaming.Aeson
replicates Renzo Carbonara's Pipes.Aeson
. It also includes materials for appying the additional parsers exported by json-streams
library, which have some advantages for properly streaming applications as is explained in the documentation.
Data.Attoparsec.ByteString.Streaming
in turn pretty much replicates Renzo Carbonara's Pipes.Attoparsec
module. It permits parsing an effectful bytestring with an attoparsec parser, and also the conversion of an effectful bytestring into stream of parsed values.
