Quite a bit of guesswork though. Feel free to edit.

I've done some additional matching and colour coding. Btw here is how the raw data was generated... |classes| outfile := (FileStream newFileNamed: '/tmp/NB-hierarchy3') lineEndConvention: #lf. classes := Smalltalk allClasses select: [ :c | (c name beginsWith: 'NB') ]. classes addAll: (classes flatCollect: [ :c | c allSuperclasses ]) asSet asOrderedCollection. Object printSubclassesOn: outfile level: 1 filter: classes. outfile close. I needed to add printSubclassesOn:level:filter: as a tweak to the existing printSubclassesOn:level:filter: that I thought might be generally useful, so I attached it to an issue... Extend ClassDescription>>printSubclassesOn:level: to have a filter https://pharo.fogbugz.com/default.asp?19077 cheers -ben
