Should you override #doesNotUnderstand: and #respondsTo: together?
by Thiede, Christoph 31 Jan '20

31 Jan '20

Hi all, just struggled over the fact that Json objects provide access to their keys via #doesNotUnderstand:, but they do not override #respondsTo:. Example: json := Json readFromString: '{"foo": 42}'. json foo. "42" json respondsTo: #foo. "false" Question: Is this discrepancy indeed desired behavior? Or should we rather always try to override #doesNotUnderstand: and #respondsTo: together? Best, Christoph

[ANN] Guardians 0.93
by Stéphane Rollandin 29 Jan '20

29 Jan '20

Hello, I just released an update to Guardians: http://www.zogotounga.net/comp/guardians.htm Guardians is a remake of the cult 1986 game The Sentinel. It is implemented in Squeak via Balloon3D and Wonderland. The look and feel of Guardians is different from the original game in part because the technology is different, obviously, and in part by design. Nonetheless, this new version features a mini-game that attempts to faithfully reproduce the atmosphere and gameplay of The Sentinel in its Atari ST incarnation. Press Y to try it. Also, thanks to the VM team and notably Eliot and Nicolas, the 3D plugin is now much more stable, and the game does not crash anymore. Stef

Found at last - swiki sources!
by tim Rowledge 28 Jan '20

28 Jan '20

Some time ago I asked if anyone knew where the sources for the swiki we use for wiki.squeak.org might be found and I'm pleased to report for the record that I may well have found them. Whilst bumbling around the swiki hoping to tidy up some documentation I came across http://wiki.squeak.org/swiki/15 "Downloading Swiki Servers". And lo, what did I find but actual downloadable packages that at least appear to be swiki code! My Ghast is well and truly Flabbered. Notice how this page is quite different to most of the swiki pages. How it is locked in a different way. I think we're in the Twiglet Zone here folks... or at least a different wiki in the swiki. So now the obvious question is whether it is interesting, practical and worthwhile to make use of this to create an updated version. IIRC we still run the swiki on an ancient vm & image set; perhaps it would be good to modernise? tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Abdicate (v.), to give up all hope of ever having a flat stomach.
