This library provides Haskell bindings to zeromq (http://zeromq.org). · Current status Version 0.1 - This software currently has *alpha* status, i.e. it had only seen very limited testing and changes to its API might happen. This software was developed and tested on Linux 2.6.31 with GHC-6.12.1 using the current git HEAD of zeromq2 (http://github.com/sustrik/zeromq2). · Installation As usual for Haskell packages this software is installed best via Cabal (http://www.haskell.org/cabal). In addition to GHC it depends on 0MQ of course. · Usage The API mostly follows 0MQ's. Public functions are: - init - term - socket - close - setOption - subscribe - unsubscribe - bind - connect - send - flush - receive - poll One difference to 0MQ's API is that sockets are parameterized types, i.e. there is not one socket type but when creating a socket the desired socket type has to be specified, e.g. 'P2P' and the resulting socket is of type 'Socket P2P'. This additional type information is used to ensure that only options applicable to the socket type can be set, hence ZMQ_SUBSCRIBE and ZMQ_UNSUBSCRIBE which only apply to ZMQ_SUB sockets have their own functions ('subscribe' and 'unsubscribe') which can only be used with sockets of type 'Socket Sub'. Other differences are mostly for convenience. Also one does not deal directly with 0MQ messages, instead these are created internally as needed. · Examples The test folder contains some simple tests mostly mimicking the ones that come with 0MQ. · Bugs If you find any bugs or other shortcomings I would greatly appreciate a bug report, preferably via http://github.com/twittner/zeromq-haskell/issues or e-mail to email@example.com
