# Lomongo

_Lomongo (ISO-639-3: lol) is a language spoken by several of the mongo peoples

in the Democratic Republic of Congo_

Lomongo is a driver for MongoDB written in Scala and trying to be really

functional (not through using funny characters, though). It uses Netty for IO.

## Installation and Usage

Install using `sbt`:

    sbt update

    sbt install

For an example of how to use the driver, see `main.scala`.

## Motivation

Existing drivers for MongoDB are quite clumsy to work with from Scala, mainly

because they try to create a Scala interface on top of the Java driver, which is

not only very OO, but also very weakly typed. Thus, those drivers make heavy

use of implicit conversions, which predictably goes horribly wrong in

non-trivial use-cases. However, trying to create a functional, strongly typed

Scala driver requires one to re-implement the protocol and serialization layers,

hence this project may or may not reach production quality (and will be maintained

actively enough to stay there). Thus, patches and contributions are highly

welcome.

## Todo

* some of the administrative commands have no wrappers yet

* map/reduce is not implemented at all

* BSON encoding/decoding should be decoupled from Netty `Channel`s

  * compare performance / GC characteristics of:

    * Stream (including forcing / wrapping in Channel)

    * Array of nested 'word' Arrays wrapped in Channel

    * NIO ByteBuffer (including allocating more capacity)

* the interface follows the native API very closely -- a 'funny characters' API,

  possibly exposing 'Collection'-semantics, could be nice
