What I'd like to do is have a user be able to enter these two items into Data Definition fields:

Tweet text:
MSU geologist Masako Tominaga & her students map the ocean floor to study the earth’s polarity.

Trackable URL:
go.msu.edu/FLF5

Then be able to generate a "tweet this" link in Velocity that would result in a final URL like:

http://twitter.com/intent/tweet?text=MSU+geologist+Masako+Tominaga+%26+her+students+map+the+ocean+floor+to+study+the+earth%E2%80%99s+polarity.+go.msu.edu%2FLF5+%23SpartansWill

Any help would be appreciated, I figured that it might have been something that someone already has done.

   Hi,

   Once you set up the Data Definition fields, you can use the Velocity Escape Tool to encode the string and URL.

   Consider the following snippet to get you started:

   #*
   Assuming the following Data Definition XML:
   
   <system-data-structure>
     <group identifier="tweet" label="Tweet Link">
       <text identifier="text" label="Text"/>
       <text identifier="link" label="Link"/>
     </group>
   </system-data-structure>
   *#
   
   #set ( $text = $currentPage.getStructuredDataNode("tweet/text").textValue )
   #set ( $link = " ${currentPage.getStructuredDataNode('tweet/link').textValue}" )
   
   ## If the total tweet length is greater than 140 characters, truncate the text accordingly
   #set ( $fullTweet = "${text}${link}" )
   #if ($fullTweet.length() > 140)
       ## Find the maximum length for the text by subtracting the link length and 3 (to account for the ellipsis added during truncation).
       #set ( $truncateLength = $_MathTool.sub(140, $_MathTool.add($link.length(), 3)) )
       #set ( $text = $_DisplayTool.truncate($text, $truncateLength, "...") )
   #end
   
   http://twitter.com/intent/tweet?text=${_EscapeTool.url($text)}${_EscapeTool.url($link)}
   

   Note: this code will also account for cases where the entire tweet text is greater than 140 characters and will truncate the text before adding on the url.

   Please let me know if you have any questions.

   Thanks!
