CouchDB Ruby Libraries

This is a quick list of CouchDB Ruby libraries. Need to connect Ruby to CouchDB? Try one of these!

  1. CouchRest - hosted at GitHub, this library by Chris Anderson (jchris), has a low level component and a high level component.
  2. RelaxDB - also hosted at GitHub, this library provides a base class that your models will extend (similar to the high level component provided by CouchRest.) RelaxDB adds pagination support as well as has_many and belongs_to relationship support.
  3. CouchObject - this library is unique because it is implemented as a module, to be included in your model class. This library also has both low level and high level components.
  4. Basic Model - from topfunky, this library was featured in the PeepCode CouchDB episode. Your model classes extend BasicModel.
  5. ActiveCouch - tries to look like ActiveRecord. Supporting a simple find method to query views. Views are defined as Ruby classes, and loaded via rake tasks.
  6. CouchFoo - attempts to replication ActiveRecord look and feel. Newer than the rest of the libraries, so takes lessons learned from all other Ruby libraries.


I've personally used CouchRest, but only its low level components.

For much more in depth analysis of many of these libraries, a little place of calm has a great eight part series on writing Ruby on Rails applications with CouchDB which covers ActiveCouch, RelaxDB, and Basic Model.

Lists and arrays in Dart

(This is Part 3 in a series about Dart. Check out Part 2, Function in Dart .) Warning : We expect the Dart libraries to undergo potentially sweeping changes before Dart goes to alpha. This document is relevant as of 2011-12-22. Intro Dart is a "batteries included" effort to help app developers build modern web apps. An important "battery" is the bundled core Dart libraries, providing common and rich functionality. Dart is building a solution for large, complex web apps, and providing well tested, integrated, and common libraries is key to helping a web app developer be more productive out of the box. The Collection libraries are a crucial set of APIs that Dart developers get for free. Much more than simple arrays and maps, the Collection library includes standard ways to filter, iterate, inspect, compose, and sort your data. This post specifically looks at List<E> , Dart's ordered, indexable collection of objects. Aside: The Dart project is lucky

Converting Array to List in Scala

Now, this has to have a built-in somewhere in Scala , because it just seems too common. So, how to convert an Array to a List in Scala? Why do I need this? I needed to drop to Java for some functionality, which in this case returns an Array. I wanted to get that Array into a List to practice my functional programming skillz. **Update**: I figured out how to convert Arrays to Lists the Scala way. Turns out it's a piece of cake. val myList = List.fromArray(Array("one", "two", "three")) or val myList = Array("one","two","three").elements.toList The call to elements returns an Iterator , and from there you can convert to a List via toList . Nice. Because my first version wasn't actually tail recursive, what follows is a true tail recursive solution, if I were to implement this by hand. The above, built in mechanism is much better, though. object ArrayUtil { def toList[a](array: Array[a]): List[a] = { d
