Given that there's 'From Smalltalk/X, Version:6.2.1 on 30-01-2012 at 10:57:56 PM' in files (like https://github.com/mkobetic/Xtreams/blob/master/stx_goodies_xtreams_core.st) it might be possible that this is the Smalltalk/X port's repository. frank

Better ask Martin :-) I know he's now playing now with Xtreams & Cypress to see how it can be used to maintain cross-dialect projects. So you may need an up-to-date implementation of Cypress reader/writer. Jan

How up to date is https://github.com/mkobetic/Xtreams/ ? That's surely not the "canonical" repository, which would be in the Cincom Smalltalk Public Repository. I think? Anyway, assuming it's up to date, one promising approach to using Martin Kobetic's repository directly is: * have a way of importing chunk format stuff from a GitHub repository (see Squeak's inbox for my doesn't-support-filetree-yet-but-can-do-chunk-format InstallerGitHub (and I plan to submit a Gofer patch to do the same)) * load into an Environment (Squeak 4.5 can do this, modulo its alpha state). It might even be possible to import into an Environment with the prefix-adding import and then fileout/monticelloise the resulting things as a prefix-using, non-Environments-requiring blob ready for everyone to use. frank

Ok resumed learning of Athens, did look through and experimented with the steps of the tutorial , I think I understand the basics now. Started from a fresh image reinstalled everything and no longer save my image with Athens Tutorial open so there is no segfault.But the error remains.

And then you need to save the file, and then you need to reload the map ... Again save the file, and reload ... Each time you reload the program restart at the beginning of course. Yeah that would look better in Pharo, basically the same without reload button but runtime behavior modifications. 2013/4/18 Igor Stasenko <siguctua(a)gmail.com> > On 18 April 2013 08:33, Torsten Bergmann <astares(a)gmx.de> wrote: > > I read about this game today.

[Pharo-project] the fun theory

by Torsten Bergmann

I read about this game today. It is written in Lua and one can play the game by editing Lua scripts (in an external editor) to optimize trains for transportation: http://trainsportedgame.no-ip.org/index.php http://www.youtube.com/watch?v=yFKZd8nEQyA This game combines learning and playing and is a nice attempt to get people into coding. Maybe we can raise the Pharo fun factor by getting people into something similar...

This worked fine until the Opal repo was removed. I copied over the files. (This means that "just loading a Config" style of integrating something is not working at all) Marcus
