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.
Best, Steffen

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

@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!

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