You can't bring me down: a kind of meta message

by StÃ©phane Ducasse

Hi guys I was thinking after the discussions I got with igor about the efforts we spend on the build servers and vm infrastructure: sometimes we/you have a vision and a good one but people do not get it or do not follow or are busy and do not get that if they would spend 5% of time doing little things then you would not lose your faith or days of work. Yes this is like that: for example igor fixes are not included in VM code. This happens. So may be one of these days we will have to think about what we really want for VMs and do it. Now you should not let people get your vision down. This is too important and fun when your vision is cool. You can't get me down (one of the best suicidal tendencies song). http://www.youtube.com/watch?v=CrctcJqfpXU Stef

I understand your frustration. It is mine too. This is why we are working steadily on fixing libraries. Indeed we are missing simple and powerful widgets like grids. Have a look at UITheme examples.

So what can we do? Blog and twitting more and having more pharo presentations. But we are doing that so may be others should do it too. Stef

Hi BB is the one click image of Pharo by example not working on linux? If i does use this is one. Why because PBE is working on 1.0 and does not have the changes to run Cog.

Is your code available somewhere on SqueakSource ? Laurent.

So tantalizing...

by Tony Giaccone

Every time I look at smalltalk, I'm blown away with how cool it is to work with and each time I try to get started, my efforts are stymied pretty quickly. I understand message passing, and I understand the basics of the syntax, but I'm having a very hard time understanding how to use the class libraries. I am trying to build a very small app. A simple data editor and browser. I've been able to follow an example in the code (simple grid example). I can now display my objects in a window, with four of the attributes listed in the editor. Now I can select an time and change it in place in the list editor but that change doesn't make it into the "database" (my ordered collection). It is not clear to me at all how to select a line in a MorphTreeMorph. Nor how to save the change when the user tabs out or hits return. Any help would be appreciated. Tony

All screenshots for example of PBE were done with the system browse O2 which doesn't even work now in Pharo 1.3. In addition, examples, and code of the book have changed/removed in Pharo 1.3. So, no. It is easy. If you want PBE image, then use the correct VM for it. Now, PBE 2 book is around the corner. Hopefully this book is based on new versions of Pharo and PBE2 image will be probably be cog compatible.
