A set of tools that simplify handling multilingual content in Plone based on LinguaPlone

Project description

Project Description

Plone 4 is supported starting with version 1.4.0 - Bugfix releases for Plone 3 will be continued in the 1.3.x series.


slc.linguatools offers a set of functions that are designed to make life easier when dealing with multilingual sites, especially those with several different languages.

Often you have the requirement that you want to do the same action for all translations of an object. In a site with ten, twenty or more languages, doing this manually is not an option any more.


slc.linguatools offers assistance for the following use cases:

  • Set title or description:

    Set the title / description on all translations; either directly to the string you entered, or based on an i18n label and domain

  • Rename an object

    Rename all translations to the id (short name) you entered

  • Set portlets

    Propagate the portlet settings of the canonical object to all translations, either for all slots or the one you chose. Block / unblock portlet inheritance per slot.

  • Workflow

    Publish / retract / etc. all translations

  • Catalog reindex

    Reindex all translations of an object

  • Deleter

    Delete all translations of an object

  • Cut and paste

    Cut all translations of an object and paste them to another folder

  • Property handling

    Set a property with id, type and value on all translations. Example: Set string property “layout” to “@@my-shiny-view”. Delete an existing property.

  • Marker interfaces

    Set or remove a marker interface on all translations of an object. The interfaces available for setting and removing are provided by a vocabulary and are the same as on the “Interfaces” tab in the ZMI.

  • Subtyping (if p4a.subtyper is installed)

    Set a subtype on all translations; remove a subtype

  • Translate an object

    Create a translation of the current object for all available languages. The AT attributes that should be copied over can be selected. If the object is a Collection, then all criteria are copied as well.

  • Copy the values of individual fields

    Using the “Translate this object” function mentioned above and selecting the “Translation exists” option, you can copy the values of individual AT fields to all translations, such as dates, tags (Subject) and Collection criteria.

Requirements and Installation

This package only works and makes sense if you have LinguaPlone installed.

Add “slc.linguatools” to the eggs and zcml sections of your buildout configuration. After running buildout and restarting your instance, go to the Site Setup -> Add-on Products, choose slc.linguatools and click “install”.

A tab named “Lingua Tools” will then appear on all translatable objects.

Enabling support for language neutral folders in TinyMCE

If you have the default language folder structure (e.g. created by LinguaPlone’s @@language-setup-folders), you will have a top-level folder that provides INavigationRoot for every language in your site (/en, /de, /fr, etc.). In this case it will not be possible to have a common language-neutral folder (e.g. for images) that is accessible in TinyMCE. For details see:

In this same ticket, a patch to the getBreadcrumbs method of TinyMCE was provided by Robert Niederreiter. This patch is included in slc.linguatools, but not activated by default. To activate it, you need to set an environment variable called PATCH_TINYMCE_BREADCRUMBS.

You can do this by adding the following to your zope.conf:


If you use Buildout, you don’t want to edit zope.conf directly, since it will be overwritten by the next buildout. Rather, edit your buildout configuration and add the following to the [instance] section:

zope-conf-additional =


The first version of this tool featured a manually written BrowserView. During the Plone-Conference 2009 sprint, a second version that uses z3c form was written. This is the version visible by default via the “Lingua Tools” tab. The original version is still accessible under @@linguatools-old.


Please also see test/lttest.txt for a doctest that guides you through the basic functionalities.
