twitter-text¶ ↑

A gem that provides text processing routines for Twitter Tweets. The major reason for this is to unify the various auto-linking and extraction of usernames, lists, hashtags and URLs.

Extraction Examples¶ ↑

# Extraction
class MyClass
  include Twitter::Extractor
  usernames = extract_mentioned_screen_names("Mentioning @twitter and @jack")
  # usernames = ["twitter", "jack"]
end

# Extraction with a block argument
class MyClass
  include Twitter::Extractor
  extract_reply_screen_name("@twitter are you hiring?").do |username|
    # username = "twitter"
  end
end

Auto-linking Examples¶ ↑

# Auto-link
class MyClass
  include Twitter::Autolink

  html = auto_link("link @user, please #request")
end

# For Ruby on Rails you want to add this to app/helpers/application_helper.rb
module ApplicationHelper
  include Twitter::Autolink
end

# Now the auto_link function is available in every view. So in index.html.erb:
<%= auto_link("link @user, please #request") %>

Usernames¶ ↑

Username extraction and linking matches all valid Twitter usernames but does not verify that the username is a valid Twitter account.

Lists¶ ↑

Auto-link and extract list names when they are written in @user/list-name format.

Hashtags¶ ↑

Auto-link and extract hashtags, where a hashtag can contain most letters or numbers but cannot be solely numbers and cannot contain punctuation.

URLs¶ ↑

Auto-linking and extraction of URLs differs from the Rails default so that it will work correctly in Tweets written in languages that do not include spaces between words.

International¶ ↑

Special care has been taken to be sure that auto-linking and extraction work in Tweets of all languages. This means that languages without spaces between words should work equally well.

Hit Highlighting¶ ↑

Use to provide emphasis around the “hits” returned from the Search API, built to work against text that has been auto-linked already.

Conformance¶ ↑

To run the Conformance suite, you’ll need to add that project as a git submodule. From the root twitter-text-rb directory, run:

git submodule add git@github.com:twitter/twitter-text-conformance.git test/twitter-text-conformance/
git submodule init
git submodule update
