Just try to write tests for TilingWM please :) For TWMBar I'm not sure this will be a final GUI. Ideally all will be keyboard driven, I have to play with KeyMapping. I also think the UI theme Patrick has cleaned fits better with TilingWM: To try it: Gofer it squeaksource: 'PBASandbox'; package: 'PBSandbox'; load. StandardUITheme beCurrent. See screenshot.

Re: [Pharo-project] [Pharo-users] some news about the consortium

by StÃ©phane Ducasse

Thanks a lot for your trust! For us, we receive that as gift and responsibility. We feel honored. If was never and will never be a question of ego or power. What I learned is that when you really want something to happen the best thing to do is to do it. May be people will join and you will have fun. At the minimum you will not get frustrated not to have dare to do it. We did that with ESUG, Squeak and Pharo. so there is a pattern :) Stef On May 25, 2011, at 9:56 PM, Michael Forster wrote: > On Wed, May 25, 2011 at 1:37 PM, StÃ©phane Ducasse > <stephane.ducasse(a)inria.fr> wrote: >> Hi pharoers >> >> yesterday we got a meeting with INRIA people and we discussed the creation of an INRIA consortium. >> We will follow the INRIA process and propose officially the creation.

[Pharo-project] tests ui errors in headless mode

by Tudor Girba

Hi, We have some smoke tests in Moose that basically spawn a UI and check for Error. This used to work when running headless in Pharo 1.2 but now they fail in Pharo 1.3. I believe this has to do with the new changes in the UI Manager, but I do not know what to do. To reproduce the problem, you can simply call a Pharo-1.3.image in headless mode and file in the attached st file that: - installs a simple test: HeadlessTest>>testStartup self shouldnt: [1 inspect] raise: Error - loads HudsonTools - runs the test and outputs the XML file report - although the test should pass, it raises the error: HeadlessStartupTest(TestCase)>>signalFailure: HeadlessStartupTest(TestCase)>>assert: HeadlessStartupTest(TestCase)>>shouldnt:raise: HeadlessStartupTest>>testStartup HeadlessStartupTest(TestCase)>>performTest Can anyone help?

Re: [Pharo-project] cog vm for iOS

I'm going to use this post to talk a bit about Pharo in iOS, because it is more complex than "having a vm working" >>> But first, a summary of where we stand: >>> 1) The Stack VM is working with iPhone/iPad, but needs some minor adjustments (some tuning). >>> One problem here is that I didn't integrate it to CMakeVMMaker (and as a consequence, to hudson), so build it is not a trivial task. But I will, as soon as some one jump and say "hey, I'm going to use it, for real!"... or as soon as I can find a free afternoon... it is planned (and I worked a little on this), but it is not a priority right now :) >>> 2) The Cog (I mean, the jitter) will never work on iPad/iPhone, because of the apple license (clause 3.3.2) and because of the security sandbox policy. But I think the Stack VM can do a pretty job. No, I'm not going to prepare this just for recreational purposes because I do not have the time, and the community work I do should be spent in things the community can use... and I think that Eliot (who is, in fact, the one who can do this, I'm just a builder) will think similar :) >>> >>> So... if we have a vm running on iOS, why there is no a legion of fellow pharoers taking over the appstore? >>> >>> Well... because it is not enough. >>> There are several problems, besides the vm working or not (to be fair, the interpreter vm works on iphone since at least two years, and John is the only one who succeed on pushing some nice smalltalk apps into the appstore). >>> The main problem is that our morphic world is ok for desktop working, and some times for desktop commercial apps (like those of pinesoft), but it just can't be used to create real apps for the iPhone/iPad market. There are some exceptions, like some eToys work and probable the developing of games like "tic-tac-toe" or so... (I mean: graphic games who can be done with morphs). But as a general rule, you can't do a real app in pharo/squeak who runs in the iPhone/iPad and can be sold in the appstore. >>> To overcome this problem, what John does is to create the full view in Cocoa, and "plug" the model to pharo/squeak images, using pharo as a module of a cocoa application. This can be done for several apps (and the fraction calculator is an example), but fails when you want a deeper interaction (because of the cost, not just in "programming time" but also the "translation time" between the cocoa app and pharo: it is just not good enough to bring a cool user experience (at least in all my experiments it was the case) >>> >>> There is another possible approach, who I think is the better in the long way, and that is what I was doing with Deimos project: using a bridge to construct, in pharo, real cocoa UI objects... the advantages with this are obvious. Nevertheless, there are also some problems with this approach: >>> 1) last year I was working on this, and apple changed a clause. The result can be expressed as if they executed: 'deimos become: shit'. Months after they review the policy, but I was concentrated on Mars (the desktop equivalent to Deimos). I will continue this, but first I want to finish Mars, and also I need to solve the problem below: >>> 2) there are also a performance problem with the ObjectiveC plugin and callbacks. In all my experiments, I never went below 70ms executing a callback from cocoa to pharo (and that's necessary, for example, to fill tables). The minimum time needed to have a cool "scroll" effect on tables is 40ms. Of course, iPhone 4 is better than 3gs... but the problem remains. The real thing is that ObjectiveC plugin relies on a semaphore communication model, and that's not good enough. So... I think the better approach here is to port FFI-Callback plugin (latest work of Eliot) to iOS. FFI-Callback plugin uses a whole different approach, who can overcome this performance issues (and some other who's not the case mention here). >>> >>> So... yes... I would love to finish this soon. But right now, other issues are top in priotity, and I just can't promise a release date.

[Pharo-project] some news about the consortium

by StÃ©phane Ducasse

Hi pharoers yesterday we got a meeting with INRIA people and we discussed the creation of an INRIA consortium. We will follow the INRIA process and propose officially the creation. For that we will have to present a proposal by end of June so we will do it. I would like to see the consortium taking life by end of the year and there are still some work to be done there. Stef
