OVERVIEW

Action Streams for Movable Type collects your action on third party web sites into your
Movable Type web site. Using it, you can aggregate those actions for your reference, promote
specific items to blog posts, and stream the whole set to your friends and readers. Action
Streams are a powerful part of your web profile.

The plugin adds the ability for your Movable Type authors to list their accounts on third
party web services. A periodic task then automatically imports your authors' activity on those
services using XML feeds (where provided) and scraping HTML pages (where necessary). Your
authors can then publish their action streams completely under their control: the provided
template tags make it possible to display authors' accounts and actions on any page powered by
Movable Type. The example templates and the provided template set also use the XFN and hAtom
microformats and provide web feeds to integrate with tools your readers may be using.


PREREQUISITES

- Movable Type 4.1 or higher
- Scheduled task or cron job to execute the Periodic Tasks script (see below)

The Action Streams plugin ships with all of the external libraries you should need to run it.

Note: Action Streams does not work when run-periodic-tasks is run in daemon mode.


INSTALLATION

  1. Configure a cronjob (see below) for the script run-periodic-tasks.
  2. Unpack the ActionStreams archive.
  3. Copy the contents of ActionStreams/extlib into /path/to/mt/extlib/
  3. Copy the contents of ActionStreams/mt-static into /path/to/mt/mt-static/
  4. Copy the contents of ActionStreams/plugins into /path/to/mt/plugins/
  5. Navigate to your profile, and click on "Other Profiles."
  6. Build a list of your accounts that you wish to display and stream actions from.
  7. Edit your stylesheet to include needed CSS. (see STYLES below)
  8. Edit your templates to display your other profiles and your Action Stream. (see
     example_templates folder)  A template set is also provided for convenience.
  9. Edit the plugin's settings to enable automatically rebuilding your blog as new
     actions are imported.  This setting is under each of your blog's plugin settings.


CRONJOB

Add the following lines to your crontab to execute the script at the hour and 30 minutes
past the hour:

  # Movable Type's scheduled tasks script:
  0,30 * * * * cd /path/to/mt; perl ./tools/run-periodic-tasks


STYLES

To add icons to your Action Streams and other basic styling, add the following line to 
the top of your main stylesheet (normally styles.css). 

  @import url(<MT:StaticWebPath>/plugins/ActionStreams/css/action-streams.css);

The classes used in the template code examples use the same classes as the default templates
and thus they work well with the default themes.


TEMPLATE CODE

The example_templates folder within the Action Streams plugin includes example widgets and
index templates which make use of an author's Other Profiles and Action Stream.  Though it
is possible to create Action Streams combining actions from multiple authors, all of the 
examples display profiles or actions from a single author.

The following template code will produce a list of actions for the author "Melody Nelson":

  <mt:ActionStreams display_name="Melody Nelson" lastn="20">
      <mt:if name="__first__">
  <div class="action-stream">
      <ul class="action-stream">
      </mt:if>
          <li class="service-icon service-<mt:var name="service_type">"><mt:StreamAction></li>
      <mt:if name="__last__">
      </ul>
  </div>
      </mt:if>
  </mt:ActionStreams>

It is recommended that you add the above code as a template module or widget to make it
easier to include and display profile actions throughout your web site.

For more detailed examples see the templates in the example_templates directory.

There are additional template tags, such as mt:StreamActionThumbnailURL, which need to
be documented better in the future.
    <mt:setvarblock name="thumb_url"><mt:StreamActionThumbnailURL></mt:setvarblock>
    <mt:if name="thumb_url">
        <div style='padding-left: 20px; padding-bottom: 10px; padding-top: 5px;'>
            <img src='<mt:var name='thumb_url'>' />
        </div>
    </mt:if>
