Hi Wanted to let you know that the GLTTRenderingDemo is working again on Windows. Thanks a lot for your effort!

Hello Bernat, You should ask directly the developers of this project. Maybe they are not registered to this mailing list. You should find their mail addresses on the squeaksource page of this project.

Re: [Pharo-users] [Athens] Finding if a line passes through a specific pixel .

by kilon alios

Libraries have no job. They have no obligations. No things they should or must do. They have methods that define what they can do. So there is nothing stopping Athens from having such a feature. Hence my question. But I found the formula for this, looks like i will be learning linear algebra and geometry.

Yes, it works on the edge of Spec capabilities and it needs to use some hacks that are not possible in the recent Spec version. -- Pavel 2013/11/14 Juraj Kubelka <juraj.kubelka(a)gmail.com>: > Thanks, I will try it. > > Are there some changes in Pharo 3, that does not allow to use it in Pharo 3? > > Cheers, > Jura > > El 14-11-2013, a las 16:57, Pavel Krivanek <pavel.krivanek(a)gmail.com> escribiÃ³: > >> I fixed the recent experiments with the new Spec versions so now it >> should work in Pharo 2.0.

Nautilus + Periscope

by Torsten Bergmann

Pavel wrote: >I fixed the recent experiments with the new Spec versions so now it >should work in Pharo 2.0. It really needs a configuration :-) You mean a configuration like the one I attached :) Did you notice the new "Config+" button on the metacello browser - it helps creating new configs. I also added a postload for plugin registration. Feel free to use and put into your STHub repo. I found two bugs in Periscope using Pharo2.0 #20627: 1. When one enters "Obj" to search for object it crashes in the spotlight 2. When one opens tools like the Configuration browser they show up inside of the area of Periscope... If this gets fixed and config gets usable for Pharo 2.0 then do not forget to add the updated config also to "MetaRepoForPharo20" on SS3. This way it will show up in the config browser and can easily be loaded. Thx T.
