add/create mediniTags via JavaScript

It is possible to create/add mediniTags to objects via JavaScript?
If yes how

Hi Justin,

Yes, it is possible to add mediniTags via JavaScript, but not by modifying the mediniTags list directly.

mediniTags is a derived property, so code such as:

element.mediniTags.add("myTag")

does not work.

Instead, create a new BasicEList, copy the existing tags, add the new tag, and then write the complete list back using mediniSetTags(...):

// $EXPERIMENTAL$

var BasicEList = bind("org.eclipse.emf.common", "org.eclipse.emf.common.util.BasicEList", false);


var element = selection[0];

var newTags = new BasicEList();


newTags.addAll(element.mediniTags);

newTags.add("myTag");


element.mediniSetTags(newTags);

A few notes:

• mediniSetTags() expects the complete tag list, so you build a new list and assign it back.
• medini prevents duplicate tags, so re-running the script will not create the same tag multiple times.
• Newer versions of the scripting helper.js library also provide convenience functions such as:
  • hasTag(...)
  • addTag(...)
  • removeTag(...)

These helper functions are easier to use when available, but internally they rely on the same tag API.

I hope that helps. Happy Scripting!
Nils
