[Pharo-project] How to handle Squeak / Pharo differences

[laurent laffont]

Hi,

I've tried to load Koans (
https://www.hpi.uni-potsdam.de/hirschfeld/trac/SqueakCommunityProjects/wiki/smalltalk_koans)
on Pharo.

In KoanInterface>>progressHeight
^Preferences standardButtonFont height + 25

but Preferences is removed from Pharo. Which project can I look at to see
how to handle common Squeak / Pharo incompatibilities ?

Cheers,

Laurent
