Dear all, thanks for the many suggestions. I didn't had time to test all import/export ways yet. But for now, I can report on two: 1) NGFileOuter Unfortunately It raised several MNUs in my image. I'll investigate them later. 2) FileOut30 (VW Contributed) I was able to file out the code except for the package definition. Replacing {category: ''} in the class definitions with {package: 'Transducers'} fixed that. However, methods that extend existing classes did not end up in the Transducers package. Is there a similar easy change to the file-out making that happen? Also I'd like to add the package comment if that's possible. Most things appear to work as far as I can see. Two exceptions: 1) Random is a subclass of Stream in VW and in Pharo it is not. Hence, I'll have to copy some methods from Stream to Random. 2) I used #beImmutable in VW but I couldn't yet figure out how to make objects immutable in Pharo. However, until the tests are ported, I cannot guarantee. Porting the test suite will be another beast, since I rely on the excellent mocking/stubbing library DoubleAgents by Randy Coulman. I am not sure how I will handle that. In general, I think it would be really worth the effort to be ported to Pharo, too. DoubleAgents is pretty powerful and produces easy to read and understand mocking/stubbing code. Personally, I prefer it clearly, e.g., over Mocketry (no offence intended!). Attached you'll find the file-out that I loaded into Pharo. The issues above are not addressed yet. However, the following example works: | scale sides count collect experiment random samples coin flip | scale := [:x | (x * 2 + 1) floor] map. sides := #(heads tails) replace. count := 1000 take. collect := [:bag :c | bag add: c; yourself]. experiment := (scale * sides * count) transform: collect. random := #(0.1 0.3 0.4 0.5 0.6 0.7 0.8 0.9). samples := random reduce: experiment init: Bag new. samples := random transduce: scale * sides * count reduce: collect init: Bag new. coin := sides <~ scale <~ random. flip := Bag <~ count. samples := flip <~ coin.

There is a package for that NGFileOuter or something like that on cincom store. We used it for mobydic code.

If I remember correctly, there is a parcel in VisualWorks to export a file out (Squeak format).
@Milton, can you give a hand to Steffen?

Thanks for the encouraging response! First question: Which is the recommended (friction free) way to exchange code between VW and Pharo?
Cheers! Steffen

I second Sven. This is very exciting!
Let us know when you have something ready to be tested.
