== Français ==
Gadget pour éditer les balises « templatedata » de l’extension « TemplateData » de MediaWiki sans avoir à manipuler le JSON.

Un lien « TDE » est ajouté dans la boîte à outils d’édition.
Il ouvre une fenêtre de modification permettant toutes les modifications autorisées.

== English ==
Gadget to edit “templatedata” tags for the MediaWiki extension TemplateData without having to edit JSON.

A “TDE” link is added in the edition toolbox when editing a template.
It opens a window allowing all modifications to the template data.

* Authors: Ltrlg (TDE) & Salix alba (TDS)
* Last update: 2013-08-19

== Limitation ==
MediaWiki _allows_ using parameters like '{' (yes, really!)

But here, you can’t use it:
* TDS does not see these parameters
* The default name for a parameter matches /\{[0-9]+\}/ and TDE does not save if if there is any parameter containing '{'.

Of course, I don’t think anybody uses a '{' parameter. So this is not blocking in many cases.
