The Vex project is a proposed open source project under the Mylyn Docs container project.
This proposal is in the Project Proposal Phase (as defined in the Eclipse Development Process) and is written to declare its intent and scope. We solicit additional participation and input from the Eclipse community. Please send all feedback to the Eclipse Proposals Forum.
XML is being used more and more in document file formats. Such formats as DocBook, and DITA have been used to help provide a common format for document meta data. It helps separate the content from the presentation. As word processor formats move to XML like OpenOfficeXML and OpenDocument, it becomes more critical to have a WYSIWYM interface for these file formats. Most users that have to write books, articles, and other print related material don't want to deal with the tags for the files, but they want the convenience and separation of presentation that these formats provide.
The Visual Editor for XML is a set of plug-ins that provide WYSIWYM editing ability for XML files. This can be used regardless of the XML involved, and uses CSS stylesheets to provide the formatting for the presentation layer. All that is needed is a stylesheet and an appropriate XML file to edit. It hides the XML tags from the user, allow them to have a word processor like experience but store the information in the native XML format.
The Vex plug-ins will also provide an API to edit structured textual formats that are similar to XML (e.g. WikiText).
Vex's editor widget can provide the same editing convenience for those
All that is needed is a mapping between the text format and the object model used by Vex, in conjunction with CSS stylesheets to define the presentation.
There is a long lasting demand in the community for a text entry widget that also allows simple formatting and semantic tagging of the entered text. Most previous solutions were based on the browser widget, Swing or other external (not native SWT) technologies. Vex will accommodate this demand with a solution natively implemented in SWT.
Vex will be based off of a contribution from the Vex (Visual Editor for XML) project, originally created by John Krasnay and hosted at sourceforge.net. In the year 2008 this code was donated to Eclipse and has been an Eclipse Web Tools Incubator component. The goal of the project is to provide a WYSIWYM XML Editor primarily targeted for those using XML authoring file formats. It will be leverage existing XML support and frameworks from the Web Developers Tools project. Particularly, the Structure Source Editor, as well as the WTP validation frameworks. It will also make use of the DTD and XML schema support for the files as well. It provides a plug-in architecture that allows for the use with any arbitrary XML file, and creation of new CSS style sheets that can be used with existing known document formats.
All code is currently incubating with in the Web Tools Incubator project. The current committers are shooting for a spring graduation date. The code has consistent Hudson builds, and is using Git as version control system. Builds are using Maven 3 and Tycho. P2 update sites are available. The code supports DITA and DocBook formats out of the box.
All code has been reviewed and approved through the Eclipse IP Process. There are no outstanding CQs that need to be completed or approved. All past contributors on the SourceForge project have approved the relicensing of the code under the Eclipse Public License.
