== SYNOPSIS
A great example of an SOA is the Twitter API service, accessed via
sending requests to URLs and parsing the data returned. Halcyon
utilizes the widely used HTTP protocol and JSON format for handling
requests and responses, making its overall footprint light and sending
complex data trivial.
Halcyon is built on top of Rack which means it can be folded into
existing Rack application stacks, can be run on any kind of server
supported (including Thin, Mongrel, etc), and provides a great deal of
flexibility for injecting functionality.
Several example applications exist within the repository. Check them
out at http://github.com/mtodd/halcyon/tree/master/examples/.
== INSTALLATION
Halcyon can be installed with RubyGems with:
$ sudo gem install halcyon
The latest development gem can be downloaded from with:
$ sudo gem install halcyon --source=http://halcyon.rubyforge.org/latest/
If you're feeling adventurous, you can also clone the repository and
install directly from the Rake task:
$ git clone git://github.com/mtodd/halcyon.git
$ cd halcyon; rake install
NOTE: Because of platform limitations with dependencies, Halcyon by
default only ensures that the JSON pure-Ruby variant is installed. To
install the faster C-based extension, try:
$ sudo gem install json
== DOCUMENTATION
Halcyon has been under a complete overhaul of its documentation (and
is still being worked on). New articles have been written for getting
started, writing controllers, defining routes, etc, and even more
advanced topics have been touched on (or are planned), such as
integrating databases into the development of your application as well
as taking full advantage of the Rack features.
