Re: [Pharo-project] How to load Nautilus?

by Alexandre Bergel

Nautilus has all the characteristics to be a game changer. The problem I bumped into this morning is the leap I have to do to use Pharo 1.3 (Nautilus works only in Pharo 1.3). None of the software I am working on run on Pharo 1.3. I will have to do some migration work on some point.

You can also look at CompiledMethodTrailerTest for examples (see #testEncoding).
