But just this is my first impression. And the same glitch happened regarding my perception of "Class variables" item. I'm not clear on the cause. Perception is a strange thing highly influenced by what you already know. Like those magic eye stereographic images [1] that at first you can't see, but then after the image appears, its hard to *not* see it. [1] http://www.vision3d.com/sghidden/saturn.html Maybe it is the checkbox doubling the size of the whitespace (??) such that it would be better placed to the right (??), or maybe I just need to adapt. > but "instance methods" under it will not confuse you too. By having "instance methods" at the top level with "accessing" will be indented from it, I think it would be more obvious rather than cause additional confusion.

So in trying to work out why my mind faltered, I think it may be because Nautlius provides visual feedback by light-highlighting the extension package (i.e. Compression) where Calypso does not - it only highlights real protocols. https://github.com/dionisiydk/Calypso/issues/38 cheers -ben

Re: [Pharo-dev] Redline: Talking Runtime basics ...

by Stephane Ducasse

James, Nice to hear that you are still pushing. I would love to be able to developed in Pharo and deployed on red. Noury is working on the same scenario for PharoJS. May be we should organise a skype with Guille because we can use his infrastructure (hespel) to create out of Pharo automatically a kernel for Red. Guille has an infrastructure Hespel (check his phd) to - bootstrap different kernels such as Candlelight, microsqueak.. - tailor application (you give a seed expression and it collects all the mandatory methods and classes) probably like spoon He bootstrapped different small kernels during his phd. In tornado the tailoring version of Hespel we can create imae that are as small as 12k :) We put a list of the class in a techreport. https://hal.inria.fr/hal-00996908 In Pharo 70 we will use in production a bootstrap kernel: basically Pharo core with some better handled mechanisms (such as the startup) We should remove the traits from class/metaclasses to gain some space. Now our goal for this version is not to have the smallest core but a full process based on a bootstrap image. We shuffled/repackaged many classes around and we will continue to cut spurious dependencies.
