As I understood, ProfStefBrowser was discontinued: http://lists.gforge.inria.fr/pipermail/pharo-users/2011-April/001977.html Anyway, I wouldn't need the entire ProfStefBrowser with it's options for adding lessons. What I'd need though, is a navigation-bar like the help-browser offers. This is essential e.g. for a programming-tutorial consisting of some fifty lessons.

ProfStef - syntax highlighting

by Markus Schlager

Hi all, Is there any chance to get syntax highlighting back for ProfStef tutorials? Even ProfStef is black&white only in Pharo1.3. ProfStefBrowser has vanished already in 1.2. Could the helpbrowser or at least the SystemWindow used by ProfStef get an option for syntax highlighting? All this would be highly appreciated since ProfStef-tutorials are a nice way for writing course-material in order to teach Smalltalk at school. LedMorph and LedTimerMorph are great example-classes to start with teaching. I'm missing WatchMorph, though. Markus
