Re: [Pharo-project] SystemNavigation vs. SystemOrganizer

by StÃ©phane Ducasse

This idea of globals is wrong and not modular. And the idea to use global variable instead of a instance variable makes the system difficult to cut in module. A namespace holds its organization. So it should be moreâ¦.

[Pharo-project] OBPane coordinates

by Sean P. DeNigris

Am I hallucinating, or do the OB morph classes use local coordinates e.g. #center reports the distance from the topLeft, which reports 0@0? If this is really happening right now, why is this, and how do I get their global coordinates? Thanks.

I've also augmented the hierarchy with TextLiteralHTML. In Squeak there are also TextPlusJumpStart & TextPlusJumpEnd. This hierarchy is really useful and easily extensible. It provides quite a rich facility. I write my blog posts in a workspace, using binary storage to save it, and then export it in a format that wordpress consumes (HTML with implicit line breaks at new lines, i.e. <BR>'s replaced by new lines).
