[Pharo-project] Smalltalkhub

Nov. 24, 2012

Hi guys! I was a bit off the last 3 days, I was in Paris with Stef (so romantic :-p) and didn't have much time to follow the thread on Smalltalkhub that much. Just to let you know, I'm working on the next upgrade. In randon order, here's some features that will be part of the upgrade: - Several people reported issues (thanks!), and they will be fixed - As an addition to user centric projects, the concept of team will be introduced - Project owners will be able to decide if a project is - Public (read/write) (users will still have to be authentified to commit) - Read-only - Private - A better search (if I have enough time) - A "real" homepage (again, if I have time) The next iteration on it should be focused on contributing: - One public inbox per project - The ability to "copy" a repo (similar to Github's fork) - Branches? And yes, SH is opensource, people are welcome to contribute. Features are also open, and while some parts are mandatory and required by ESUG, I'm 100% open to ideas and improvements. This is for the community, not me :) Also, SH is still in beta. I will never flush the DB, but you may find bugs and want to keep a backup. The stable version will be hosted by Inria and I will eventually migrate the data on their infrastructure. Cheers, Nico

I've just browsed through the code. Nice work on modeling Chipmunk in the image via NB. Could you separate this work from Storm? I think it deserves a package on its own.

Nice example Esteban, now you need to add some explosions to the game! Curious on the usage of Chipmunk, do you replicate the walls, balls and gravity in smalltalk? Or use Athens just as "view".

[Pharo-project] smalltalkhub and project ownership
by Norbert Hartl Nov. 23, 2012

Nov. 23, 2012

Is there an explanation why in smalltalkhub every project resides below a user? I just saw that Francois moved the MongoTalk from squeaksource to smalltalkhub. With the move the project moved into francois' projects. That seems like a step back at first. In squeaksource projects are global and have certain roles attached. Thus making it easier to shift responsibility. Especially when a user takes over a project and then stops working on it what would be the workflow for this? Can projects be moved? Do we need to copy? I can see that there is a tension to mimick github. But in github I just fork a project under my own account where it can reside even if the original author abandoned the project. What would be a good way to handle that common use case? thanks, Norbert

And because Athens documentation will absolutely require a lot of illustrations, i think best would be to use HTML for it. (or something which generates html ). Making a PDF out of it is not a big deal, isn't? Of course, this is not makes class/method comments less important. But i vote for online documentation first. Because most of people don't even understand the basic concepts of paths/contours and coordinate system.. and class comments are not really helpful for that. I wanna have something like Amber documentation: http://amber-lang.net/documentation.html Also, as for the starting point, what things we should describe there, i think OpenVG spec could serve as a guiding source. www.khronos.org/registry/vg/specs/openvg_1_0_1.pdf it contains a lot of material which we can reuse for starters: matrices, coordinate system, paths and path commands etc. So, for getting started we much decide what source format we should use. and where we will host it (as an early-term solution i propose to just create a project on github). And then first step would be to make a TOC :) -- Best regards, Igor Stasenko.

[Pharo-project] Helping with Athens development
by dimitris chloupis Nov. 23, 2012

Nov. 23, 2012

So after diving in common lisp and take a look at various alternative I decided that Pharo is the best place for me to start for my Ephestos project. The first thing that got my attention is Athens , it seems to be very close to my own goal for Ephestos. So my question is how may I help Athens involve by contributing code to it ? Are there specific features I can work on ? The first part of my Ephestos project I call it Morpheas and its basically a GUI API based on morphic specialised on customised guis, meaning guis that do not look native . Athens seems a good library to base Morpheas on, so I am actually interested in expanding it. In the future I would also like to port Athens to opengl , but if cairo is fast enough for me, I may avoid it and instead focus more on porting Morphic to Athens. So my post here is to clarify the way I can contribute to Athens . I want my project Ephestos to be a contribution to the existing Pharo image and offer more GUI widgets, maybe a gui designer and some more graphic and audio tools. I think that Athens can be the base for my project so naturally I want to contribute.

For now, Athens uses the software renderer of Cairo to draw into a Cairo Surface. We get it back to the Pharo, buy telling a Form to load the bits of the Cairo surface. Would be nice to have another renderer for Athens, besides Cairo, to use a hardware accelerated renderer. OpenGL backend for Athens would be great. NBOpenGL is already there. So it would a matter of having another AthensCanvas, and AthensSurface that uses OpenGL to draw. Yet, the current scheme is fast enough! So i don't know wether this is a priority.

Dale in my goal to reduce the complexity of metacello, I'm wondering why symbolic versions could not be expressed as version: because version: #stable version: #development are symbolic versions and there is no clash possible with version: '1.1' Stef
