I'd like to introduce couch-hs, a CouchDB view server in and for Haskell. This is for the doubtless hordes of developers using CouchDB and itching to write their map/reduce functions in Haskell. I'm relatively new to both CouchDB and Haskell, but I've found them to be a satisfying combination so far. Map and reduce functions are built on the aeson monadic parser for pithy and efficient parsing of disparate document shapes. The couch-hs executable also includes development modes for compiling individual functions, for instance with an editor macro. http://hackage.haskell.org/package/couch-hs Thanks, Peter
