This is EmacsLisp for talking to mongo-db.

A quick example using Marmalade's mongo-db:

(let* ((result
        (mongo-with-open-database
            (db :host 'local)
          (mongo-do-request
           (make-mongo-message-query
            :flags 0
            :number-to-skip 0
            :number-to-return 0
            :full-collection-name "marmalade.packages"
            :query '(("name" . "fakir")))
           :database db)))
       (docres (mongo-message-reply-documents result)))
  (assoc-string
   "headers"
   (assoc-string "_latestVersion" (car docres))))

This performs a query for a single result, the car docres is used just because the result is always a list.

You can look up objects by their object id by using the bson serializer:

(make-mongo-message-query
 :flags 0
 :number-to-skip 0
 :number-to-return 0
 :full-collection-name "marmalade.packages"
 :query (list (cons "_id" (bson-oid-of-hex-string "4f65e980cd6108da68000252"))))

Dealing with mongo

Dealing with mongo seems to result in lots of little JSON documents represented as alists.

This module might help with that

Building with Elpakit

An elpakit recipe is included so you can easily build the mongo-el package.
