Re: Squeak 2.8 available
by Peter William Lount 04 Sep '00

04 Sep '00

Hi Andreas, When might you have the new sources for 2.8 up on your web site? If it will be a while, is it possible to email them to me as they are now? I just want to read them and bring myself upto date on the changes that have happened since the 2.4vm sources. Have you made the switch over to a free compilier and if so how can I get that one set up? Maybe you have instructions on a web page somewhere... Thanks... All the best, Peter William Lount peter(a)smalltalk.org p.s. Did you move to L.A.? Are you still working with disney? ---------- From: Raab, Andreas <Andreas.Raab(a)disney.com> To: squeak(a)cs.uiuc.edu Subject: RE: Squeak 2.8 available Date: August 21, 2000 7:35 PM Ned, > At least in my case, that's because (unlike the Mac and Unix > platforms) the new Windows sources don't seem to have been > made available. > > I asked about the WinCE sources some time ago on the list and > got no responses. Sorry, I must have missed that. The sources are where they've been for years now: http://isgwww.cs.uni-magdeburg.de/~raab/squeak/src/ (including the WinCE part). These sources are not quite up to date but until I've integrated Ian's proposed directory structure (and am back in LA with a decent internet connection) it's unlikely you'll see more. There will be a new (and partly restructured) set of source files with 2.8. - Andreas

That link appears to be temporary.

Test Pilots Wanted
by Dan Ingalls 04 Sep '00

04 Sep '00

Folks - I attach two changesets that are somewhat more likely than usual to cause problems in code outside the system (maybe even within). I would greatly appreciate it if some adventurous Squeakers out there would try out these changes and report anything amiss to me. (If you don't test them now, you'll be testing them after the next bunch of updates ;-). The change to rectangle>>copy is simply a move to consistency with the philosphy of Rectangles as funtional objects, and should cause no problems (heh-heh). The new implementation of italics is *much* nicer looking for any large font (try a big italic before and after). However it makes several changes in the text kernel, and my testing of MVC has not been extensive (heh-heh). Note that this new code will only take effect after you have saved, quit, and resumed, due to caching. Keeping you from getting bored - Dan

re: [enh] connectormorph for connecting morphs with lines
by schwa＠cc.gatech.edu 03 Sep '00

03 Sep '00

Hi Ned, Looks good! A short wishlist: - ability to switch between curves/polygons (as in Dan Ingalls' recent changeset) - see attached files before.gif, after.gif, and desired.gif. In before.gif, you see an ellipse connected to a star. The user has added an extra handle somewhere in the middle. When the star is moved, the result is seen in after.gif. My wish is that you could have a heuristic (eg: calculate distance from middle point to line, calculate the ratio between the distance between the morphs and the previous calculated result, and maintain this ratio as either endpoint is moved) that would preserve the intent of making the middle handle. See desired.gif for what I would like to see after moving the star Thanks!
