An additional outputfilter that enhance file and image links informations in rich text


This product add a new outputfilter that generates additional informations for Tiny MCE's internal link.

It's a substitute of `collective.tinymceplugins.advfilelinks`__, that doesn't work with Plone >= 4.3 because it uses Products.TinyMCE >= 1.3.


For every link that points to an internal content (file or image), in the rendered html will be added some new informations:

  • The mimetype icon before the link text
  • The mimetype and filesize after the link text
  • The url of a File points to the direct download


Install collective.outputfilters.enhancelinks by adding it to your buildout:



 eggs =

and then run "bin/buildout".

It doesn't need to be installed.

Extending content-types

This product is modular, so if you want to add this feature (or more features) to some custom content-types you only need to provide a new adapter for the ILinkEnhancerProvider interface:


Then provide the Python adapter code:

from collective.outputfilters.enhancelinks.adapters import BaseEnhanceLink

class YourContentEnhanceLink(BaseEnhanceLink):

There are 4 basic methods for a basic override:

def get_url_suffix(filename):
    """ Return additional suffix to append at the end of the url """

def get_icon_url(mime_infos):
    """ Return the correct mimetype icon url """

def get_extension(content_file, mime_infos):
    """ Return the filename extension"""

def get_formatted_size(content_file):
    """ Return a formatted file size """

Additional mimetype icons

If you want more mimetype icons (for example for OpenOffice documents), you could add and install `collective.mtrsetup`__ in your buildout.


This product has been tested on:

  • Plone 4.2
  • Plone 4.3
  • Plone 5.0
  • Plone 5.1

It works with Archetype-based and Dexterity-based (``__) standard File and Image content-types.
