[Pharo-dev] Setting the code highlighter for specific methods/classes

In Squeak there is a convenience method defined on Behavior to set the highlighter for the code. There was a bug report/discussion a few years ago with Lukas. It was noted that that change is mostly needed at the same time as changing the compiler/parser and the save behavior. At the time Lukas suggested to have an object representing this whole compilation context. With Helvetica this would be needed at a text range granularity, I assume. What is the current state of this in Pharo, and how do I make Nautilus (and other browsers) use a different highlighter? Stephan
