Dashing-Widget that displays a list of tweets

README.md

Twitter-List

Description

Shows a list of tweets, basically it can show any list of comments. We use it to display our Twitter account's latest "saved search" - results.

Dependencies

• Twitter for Ruby: gem install twitter (of course only if you want do display tweets.)

Usage

• Copy comment_list.html, comment_list.coffee, comment_list.scss into the /widgets/comment_list/ directory.
• Put the file twitter_search.rb into the /jobs/ directory.
• Add your Twitter API credentials to twitter_search.rb
• Customize the twitter-search as needed. E.g. add language, change number of tweets to grab. tweets = client.search(search+ ' -RT', {result_type: 'recent', lang: 'de' }).take(10)

Of course you can display any information. Just create a job to fetch the data. Currently, these fields are used:

• name The username
• body The comment body. Hashtags and twitter-handles (@username) are highlighted by javascript.
• avatar The user's avatar
• time Creation time of the tweet
• image An image can be displayed under the comment.

##Example widget:

<li data-row="1" data-col="5" data-sizex="1" data-sizey="3">
    <div data-id="twitter_search" data-view="CommentList" ></div>
</li>

Sorry : ) didnt read the comments. I uploaded the HTML, hope that helps.

Update: So I see I am not the first one missing comments on gists... here and here... Does anyone know how to get around this without manually checking for new comments on the gist page?

I had to do some modifications before I could get this working. If you're using smashing install [this gist id], the html file is put into the wrong directory. Put it in the same directory as the scss and coffee file. 2nd, the html_escape(tweet.text) method is an erb method. I removed it and things were fine.
