RSS 2.0Share your documents in Facebook or Twitter
Diego Spano. Thursday, April 7th, 2011.Greenstone has a new macro that lets you share documents in social networks or email systems, using Addtoany tool . The new macro is called _shareme_  that belongs to package Global in document.dm. The macro accepts two parameters: _1_ is the title of the link, and _2_ is the link to share. For _2_, the [srclink] is the default option, but any other metadata can be used too. The only requirement is that the value of that metadata must contain a well-formed URL that begins with “http://â€.
If _2_ is left blank, then the link will point to the Greenstone version of the document.
You have to edit your format statement and add something like this:_shareme_([dc.Title],[srclink])
and then you will see “Share+, Facebook, Twitter, Mail , LinkedIn” icons.
There is also a brief version called _sharemesmall_ that requires the same parameters and only shows Share+ icon.
The macro code is available with version 2.84. If you are using v.2.83 or earlier you have to edit document.dm file and add the following block:
**** Macro code – Begin ****
package Global
# Social network support
# Defined here in document, as the most likely place this will be used in
# within a document view, however its package is 'Global' because you
# might equally want this in a search or browse list
# _1_ = e.g. title
# _2_ = [srclink] or left empty. If left empty, then it will share the internal GS document
