configure() {|@@config| ...}

Yields to given block to configure the Twitter4R API.

    # File lib/twitter/config.rb, line 63
63:       def configure(&block)
64:         raise ArgumentError, "Block must be provided to configure" unless block_given?
65:         yield @@config
66:       end
from_config(config_file, env = 'test')

Helper method mostly for irb shell prototyping.

Reads in login/password Twitter credentials from YAML file found at the location given by config_file that has the following format:

 envname:
   login: mytwitterlogin
   password: mytwitterpassword

Where envname is the name of the environment like ‘test’, ‘dev’ or ‘prod’. The env argument defaults to ‘test’.

To use this in the shell you would do something like the following examples:

 twitter = Twitter::Client.from_config('config/twitter.yml', 'dev')
 twitter = Twitter::Client.from_config('config/twitter.yml')
    # File lib/twitter/console.rb, line 22
22:       def from_config(config_file, env = 'test')
23:         yaml_hash = YAML.load(File.read(config_file))
24:         self.new yaml_hash[env]
25:       end
Public Instance methods
featured(type)

Provides access to the Featured Twitter API.

Currently the only value for type accepted is :users, which will return an Array of blessed Twitter::User objects that represent Twitter‘s featured users.

    # File lib/twitter/extras.rb, line 19
19:   def featured(type)
20:     uri = @@FEATURED_URIS[type]
21:     response = http_connect {|conn| create_http_get_request(uri) }
22:     bless_models(Twitter::User.unmarshal(response.body))
23:   end
friend(action, value)

Provides access to the Twitter Friendship API.

You can add and remove friends using this method.

action can be any of the following values:

  • :add - to add a friend, you would use this action value
  • :remove - to remove an existing friend from your friends list use this.

The value must be either the user to befriend or defriend‘s screen name, integer unique user ID or Twitter::User object representation.

Examples:

 screen_name = 'dictionary'
 client.friend(:add, 'dictionary')
 client.friend(:remove, 'dictionary')
 id = 1260061
 client.friend(:add, id)
 client.friend(:remove, id)
 user = Twitter::User.find(id, client)
 client.friend(:add, user)
 client.friend(:remove, user)
    # File lib/twitter/client/friendship.rb, line 28
28:         def friend(action, value)
29:                 value = value.to_i unless value.is_a?(String)
30:                 uri = "#{@@FRIENDSHIP_URIS[action]}/#{value}.json"
31:                 response = http_connect {|conn| create_http_get_request(uri) }
32:                 bless_model(Twitter::User.unmarshal(response.body))
33:         end
message(action, value, user = nil)

Provides access to Twitter‘s Messaging API for sending and deleting direct messages to other users.

action can be:

value should be:

user should be:

  • Twitter::User or Integer object when action is :post.
  • totally ignore when action is :delete. It has no purpose in this use case scenario.

Examples: The example below sends the message text ‘Are you coming over at 6pm for the BBQ tonight?’ to user with screen name ‘myfriendslogin’…

 @twitter.message(:post, 'Are you coming over at 6pm for the BBQ tonight?', 'myfriendslogin')

The example below sends the same message text as above to user with unique integer ID of 1234567890… the example below sends the same message text as above to user represented by user object instance of Twitter::User

 @twitter.message(:post, 'Are you coming over at 6pm for the BBQ tonight?', user)
 message = @twitter.message(:post, 'Are you coming over at 6pm for the BBQ tonight?', 1234567890)

the example below delete‘s the message send directly above to user with unique ID 1234567890…

 @twitter.message(:delete, message)

Or the following can also be done…

 @twitter.message(:delete, message.id)

In both scenarios (action is :post or :delete) a blessed Twitter::Message object is returned that represents the newly posted or newly deleted message.

    # File lib/twitter/client/messaging.rb, line 50
50:   def message(action, value, user = nil)
51:     uri = @@MESSAGING_URIS[action]
52:     case action
53:     when :post
54:       response = http_connect({:text => value, :user => user.to_i}.to_http_str) {|conn| create_http_post_request(uri) }
55:     when :delete
56:       response = http_connect {|conn| create_http_delete_request(uri, :id => value.to_i) }
57:     end
58:     message = Twitter::Message.unmarshal(response.body)
59:     bless_model(message)
60:   end
messages(action)

Provides access to Twitter‘s Messaging API for received and sent direct messages.

    # File lib/twitter/client/messaging.rb, line 14
14:   def messages(action)
15:     uri = @@MESSAGING_URIS[action]
16:         response = http_connect {|conn|      create_http_get_request(uri) }
17:         bless_models(Twitter::Message.unmarshal(response.body))
18:   end
my(action)

Syntactic sugar for queries relating to authenticated user in Twitter‘s User API

When action is:

  • :info - Returns user instance for the authenticated user.
  • :friends - Returns Array of users that are authenticated user‘s friends
  • :followers - Returns Array of users that are authenticated user‘s followers
    # File lib/twitter/client/user.rb, line 27
27:   def my(action)
28:         response = http_connect {|conn| create_http_get_request(@@USER_URIS[action], :id => @login) }
29:         json = response.body
30:         users = Twitter::User.unmarshal(json)
31:         bless_models(users)
32:   end
status(action, value)

Provides access to individual statuses via Twitter‘s Status APIs

action can be of the following values:

  • :get to retrieve status content. Assumes value given responds to :to_i message in meaningful way to yield intended status id.
  • :post to publish a new status
  • :delete to remove an existing status. Assumes value given responds to :to_i message in meaningful way to yield intended status id.

value should be set to:

  • the status identifier for :get case
  • the status text message for :post case
  • none necessary for :delete case

Examples:

 twitter.status(:get, 107786772)
 twitter.status(:post, "New Ruby open source project Twitter4R version 0.2.0 released.")
 twitter.status(:delete, 107790712)
    # File lib/twitter/client/status.rb, line 25
25:   def status(action, value)
26:     return nil unless value
27:         uri = @@STATUS_URIS[action]
28:         response = nil
29:     case action
30:     when :get
31:         response = http_connect {|conn|    create_http_get_request(uri, :id => value.to_i) }
32:     when :post
33:         response = http_connect({:status => value}.to_http_str) {|conn| create_http_post_request(uri) }
34:     when :delete
35:         response = http_connect {|conn| create_http_delete_request(uri, :id => value.to_i) }
36:     end
37:     bless_model(Twitter::Status.unmarshal(response.body))
38:   end
timeline_for(type, options = {}) {|status if block_given?| ...}

Provides access to Twitter‘s Timeline APIs

Returns timeline for given type.

type can take the following values:

:id is on key applicable to be defined in </tt>options</tt>:

  • the id or screen name (aka login) for :friends
  • the id or screen name (aka login) for :user
  • meaningless for the :me case, since twitter.timeline_for(:user, ‘mylogin’) and twitter.timeline_for(:me) are the same assuming ‘mylogin’ is the authenticated user‘s screen name (aka login).

Examples:

 # returns the public statuses since status with id of 6543210
 twitter.timeline_for(:public, id => 6543210)
 # returns the statuses for friend with user id 43210
 twitter.timeline_for(:friend, :id => 43210)
 # returns the statuses for friend with screen name (aka login) of 'otherlogin'
 twitter.timeline_for(:friend, :id => 'otherlogin')
 # returns the statuses for user with screen name (aka login) of 'otherlogin'
 twitter.timeline_for(:user, :id => 'otherlogin')

options can also include the following keys:

  • :id is the user ID, screen name of Twitter::User representation of a Twitter user.
  • :since is a Time object specifying the date-time from which to return results for. Applicable for the :friend, :friends, :user and :me cases.
  • :count specifies the number of statuses to retrieve. Only applicable for the :user case.
  • since_id is the status id of the public timeline from which to retrieve statuses for :public. Only applicable for the :public case.

You can also pass this method a block, which will iterate through the results of the requested timeline and apply the block logic for each status returned.

Example:

 twitter.timeline_for(:public) do |status|
   puts status.user.screen_name, status.text
 end

 twitter.timeline_for(:friend, :id => 'myfriend', :since => 30.minutes.ago) do |status|
   puts status.user.screen_name, status.text
 end

 timeline = twitter.timeline_for(:me) do |status|
   puts status.text
 end

56:     uri = @@TIMELINE_URIS[type]
57:     response = http_connect {|conn| create_http_get_request(uri, options) }
58:     timeline = Twitter::Status.unmarshal(response.body)
59:     timeline.each {|status| bless_model(status); yield status if block_given? }
60:     timeline
61:   end
user(id, action = :info)

Provides access to Twitter‘s User APIs

Returns user instance for the id given. The id can either refer to the numeric user ID or the user‘s screen name.

For example,

 @twitter.user(234943) #=> Twitter::User object instance for user with numeric id of 234943
 @twitter.user('mylogin') #=> Twitter::User object instance for user with screen name 'mylogin'
    # File lib/twitter/client/user.rb, line 16
16:   def user(id, action = :info)
17:         response = http_connect {|conn| create_http_get_request(@@USER_URIS[action], :id => id) }
18:         bless_models(Twitter::User.unmarshal(response.body))
