VPRI's Worlds package for Squeak 4.5

Hello,

For those who is interested in Worlds. so gracefully described in VPRI's report "Experimenting with worlds" by Aran Lunzer and Yoshiki Ohshima, I have prepared a version of the Worlds package, that is loadable into the current Squeak 4.5 image (http://sdk.krestianstvo.org/sdk/squeak45/Worlds-sn.73.mcz).

Regards,

Nikolay

Thanks very much, Nikolay!

(For the installer, be aware that Worlds changes some core bits, like
adding instance variables to Process. You will see a debugger pop up
asking you if you wish to proceed.)

Radical man! That's SOOOO cool. Thanks for integrating this stuff.

Sad reality is it'll probably be some time before I have the bandwidth to explore "the ultimate meta-undo" but this work is just so very important.

Good on you man! Thanks for bringing it to us.

I see references to a WorldPlugin (IdentityDictionary >>
#primTestAelAt:ifNotFound: for instance). Where would we find this?

Re: VPRI's Worlds package for Squeak 4.5

Bert,

what do you think about having a repository for experimental stuff like Worlds, OMeta at source.squeak.org, bringing them closer to Squeak community?

The latest version of Worlds, refereed in the VPRI's report (http://tinlizzie.org/updates/exploratory/packages/Worlds-ael.67.mcz) is loaded fine to Squeak 4.4, but the changes introduced in Squeak 4.5 (Compiler,Parser,Encoder) break that compatibility. So, I had to correct little things and upload it to mine repository.

Regards,

Nikolay

(I only get bits of time here & there to look at Worlds, so I'll keep
adding little note emails to this thread as I find things.)

The SetTest overrides should come out of the Worlds package. Some of
the test changes are simple recategorisations (#testRemoveIfAbsent),
while others look like useful additions to trunk (#testUnion).

IMHO, just because something was developed at VPRI does not make it more special than other projects. It's great if someone takes such a project and maintains it and improves it, but the best place to put it would be in an open repository, not a squeak.org one.

That said, we did discuss the idea of "community-maintained" packages before which should live near to squeak trunk but would not be preloaded in a full release image. Rather, they would ship with a release as separate files, be tested by the build server, etc. These are the only kind of packages I think should live on source.squeak.org itself. And those may include packages originated at VPRI, but mainly many others.

However, I think no serious work has been done yet in that direction.
