by Cardinal Blue <http://cardinalblue.com>

Lin Jen-Shin ([godfat][]) had given a talk about rest-core on
[RubyConf Taiwan 2011][talk]. The slide is in English, but the
talk is in Mandarin.

## DESCRIPTION:

Various REST clients such as Facebook and Twitter built with [rest-core][]

[rest-core]: https://github.com/cardinalblue/rest-core

## FEATURES:

Out-of-box REST clients built with rest-core for:

* Dropbox
* Facebook
* Github
* Linkedin
* Twitter

Rails utilities are also included.

## REQUIREMENTS:

### Mandatory:

* MRI (official CRuby) 1.9.3, Rubinius 1.9 and JRuby 1.9
* gem rest-core
* gem rest-client

### Optional:

* gem [em-http-request][] (if using eventmachine)
* gem json or yajl-ruby, or multi_json (if `JsonResponse` or
  `JsonRequest` middlewares are used)

[em-http-request]: https://github.com/igrigorik/em-http-request

## INSTALLATION:

``` shell
gem install rest-more
```

Or if you want development version, put this in Gemfile:

``` ruby
gem 'rest-more', :git => 'git://github.com/cardinalblue/rest-more.git',
                 :submodules => true
```

## SYNOPSIS:

The simplest usage:

``` ruby
require 'rest-more'

RC::Twitter.new.statuses('_cardinalblue') # get user tweets
RC::Github.new.get('users/cardinalblue')  # get user info

linkedin = RC::Linkedin.new(:consumer_key    => '...',
                            :consumer_secret => '...')
linkedin.authorize_url!   # copy and paste the URL in browser to authorize
linkedin.authorize!('..') # paste your code from browser
linkedin.me               # get current user info

RC::Facebook.new.get('4') # get user info
```

Runnable example is at: [example/simple.rb][]. Please see [slides][] from
[rubyconf.tw/2011][rubyconf.tw] for concepts.

## Concurrent HTTP Requests:

Inherited from rest-core, you can do concurrent requests quite easily.
Here's a very quick example of getting Facebook users' names for UID 4 and 5:

``` ruby
require 'rest-more'
facebook = RC::Facebook.new(:log_method => method(:puts))
puts "rest-client with threads doing concurrent requests"
a = [facebook.get('4'), facebook.get('5')]
puts "It's not blocking... but doing concurrent requests underneath"
p a.map{ |r| r['name'] } # here we want the values, so it blocks here
puts "DONE"
```

If you prefer callback based solution, this would also work:

``` ruby
require 'rest-more'
facebook = RC::Facebook.new(:log_method => method(:puts))
puts "callback also works"
facebook.get('6'){ |r|
  p r['name']
}
puts "It's not blocking... but doing concurrent requests underneath"
facebook.wait # we block here to wait for the request done
puts "DONE"
```

Runnable example is at: [example/multi.rb][]. For a detailed demonstration,
see: [Advanced Concurrent HTTP Requests -- Embrace the Future][future]

## Rails Utilities

To be added. But you can take a look at [Facebook tutorial][] first.

## EventMachine inside Rainbows!

To be added. But you can take a look at [Rainbows configuration][] first.

[Rainbows configuration]: https://github.com/cardinalblue/rest-more/blob/master/example/rainbows.rb

## A simple interactive shell with [rib][]:

You need to install [rib][] in order to try this interactive shell:

    gem install rib

Then you can try this by running `rib rest-core`:

    rest-core>> self.site = 'https://api.github.com/users/'
    rest-core>> self.json_response = true
    rest-core>> get 'cardinalblue'

Which is using `RestCore::Universal` for accessing arbitrary websites.
