d9f5ae5951 Move pagination helper to monger.internal.pagination 2011-11-15 03:48:31 +04:00
Michael S. Klishin
3534e579b7 Add pagination support to monger.query DSL 
An example:

(with-collection coll
                  (find {})
                  (paginate :page 1 :per-page 3)
                  (sort { :title 1 }))

bd133c1afc Initial version of the monger.query DSL 
Here is what it looks like:

(with-collection "docs"
  (find { :inception_year { $lt 2000 $gte 2011 } })
  (fields { :inception_year 1 :name 1 })
  (skip 10)
  (limit 20)
  (batch-size 50)
  (hint "my-index-name")
  (snapshot))

047d5b6a88 Separating operators to Logical Operators, Query Operators and Atomic Modifiers. 
Adding docs to most of operators (still TBC), giving more examples, improving test suite.

c109702117 Rewort $operator macros to evaluate to strings and not functions 
Unlike Casbah and Korma, we already use query language data structures as close to what MongoDB uses as possible
(Clojure maps, vectors, numerics and strings are effectively JSON) so we don't need any layers on top, they won't improve
anything.

Having these operators is nice beacuse if you use atomic operators a lot, this will make sure Clojure compiler catches
typos for you. It is completely opt-in, however.

Finally, having a function inserted carries certain runtime performance cost and having $operator macros
that evaluate to themselves does not.

Per discussion with Alex.

bb169d3ae3 Adding operators DSL in order to use Clojure functions instead of hashes. 
Casbah has a similar concept called Bareword Operators.
Korma uses operators a bit differently, but idea is quite same, too. 

One of the obvious advantages is that you can make sure you didn't screw make a typo 
in operator name during compile-time. Plus, we can guarantee that there is a subset
of used / supported operators, and add them gradually, keeping track of them in one place, 
which will simplify tests, too.

758fb9e7e6 Support skip & limit for monger.collection/find and /find-maps 
As test example demonstrates, closely following DBCollection and DBCursor API has one downside:
queries that use sorting look really ugly. So monger needs to come up with a DSL à la Casbah or SQLKorma
to make this really nice.

fbd00ee151 Use WriteConcern/SAFE by default 
WriteConcern/NORMAL is ridiculously dangerous and most apps simply do not have performance
requirements to justify completely ignoring server responses.

8b22e9eef1 Extend JodaTime integration 
This is not perfect since it currently ignores output writer paramter
and assumes clojure.data.json but it is a significantly better choice than
forcing every clojure.data.json user to use JodaTime.

Michael S. Klishin
5e12f9aec2 Introduce monger.core/connect! and monger.core/set-db! 
Even though it is not idiomatic Clojure to mutate vars like this,
it is very common for many applications to only use one MongoDB
connection (so, no per-thread var rebinding) and one main database.

For those cases, these function eliminate the need for mundaine
hacks with namespace switching.
