The content of a projection document consists of portions of the Master Document.Īs you probabably guessed, when you collapse the text in the editor you see The contents of a projectionĭocument are a subset of the contents of the Master Document. However, there is also an additional Projectionĭocument attached to a Master Document. We have a Masterĭocument, which is like the document we used to use previously. Now things are a little bit more complicated. We had a document to hold the text and a corresponding view to provide the UIįor the text. Since 2.1, a whole new implementation was added in 3.0 to support the additionalĪs you can see in the figure (a) above, without folding things were very simple. Although these concepts have been in the framework Now let's look at the basic idea in the framework that allows it to just show portions Uses the class in .projection to implement Implements the infrastructure for folding in a UI independent manner. You will notice that 2 new packages have been added to the framework: You can implement folding in your plug-in too, to allow the users to fold textĪccording the structure of your plug-in's documents. The JDT text editor, which allows you to fold individual methods and classes. Starting with Eclipse 3.0 the JFace Text framework has been extended with aįeature to allow for collapsing and expanding of text.

In thisĪrticle, I explain the new projection infrastructure introduced inĪnd show how to extend the XML Editor example provided In the inherited createActions method the editor creates its Content Assist action, used when Ctrl+Space is pressed in the editor.Starting with release 3.0, Eclipse allows folding in its text editor. In the constructor, we set up a source viewer configuration, handling such issues as Content Assist, hover help, and instructing the editor what to do while the user types text.

We don t suggest that you organize your code this way, but it will show you the basic information you will have to provide to give your editor have a professional look and feel with syntax highlighting and hover help. If you want to see what the minimalist editor looks like, we did the experiment of reducing our eScript editor to a single source file with the bare minimum code required to make the smallest possible Eclipse editor ever (see Figure 19.3). Both the XML and HTML editors show how to design and arrange your code in manageable packages. Also be sure to check out Chapter 11 of this book, which describes an HTML editor framework. This will provide you with an editor supporting syntax color highlighting, Content Assist, hover help, and more. The simplest way to familiarize yourself with the Eclipse editor framework is by creating a new plug-in with a sample XML editor (use New > Plug-in Development > Plug-in Project >. This will allow you to write support for textual edition of a language with less boiler plate.Īn editor contributes to the .editors extension point, and, in practice, the class implementing the editor is typically a subclass of. Since Eclipse 4.7.M3, you can consider simply adding extensions to the Generic Editor. Contributing to Generic and Extensible editor
