I once more could not resist but showed up at 3 Democamps (Vienna, Munich and Zürich) where I showed how you can reassemble the components from our compensator research to create a smart code editor for Google Dart with:
* Syntax highlighting
* Error reporting
* Auto completion
The slides from my talk are available at Slideshare
or if you prefer it as a PDF
If you’ve some time to spare and want to see me coding a smart editor for Google Dart in 15 Minutes you can watch the recording of the session in Vienna (the interesting part starts at around minute 15 of the video)

Really nice work Tom..
I am trying to develop a code editor with code completion and other functionalities using your code at GitHub https://github.com/BestSolution-at/efxclipse-codeeditor-samples.git.
I am getting this error in DartEditor.java while building even though it is defined.
The constructor DefaultSourceViewerConfiguration(StringInput, DartPresentationReconciler, DartProposalComputer, null, null) is undefined
I’ll look at this later or tomorrow
