[ANN] SciSmalltalk v0.14
by Serge Stinckwich 17 Sep '14

17 Sep '14

Dear all, we are to happy to announce SciSmalltalk v0.14 SciSmalltalk is a new Smalltalk project, similar to existing scientific libraries like NumPy, SciPy for Python or SciRuby for Ruby. SciSmalltalk already provide the following basic functionalities: - complex and quaternions extensions, - random number generators, - fuzzy algorithms, - Didier Besset's numerical methods, - Ordinary Differential Equation (ODE) Solver. Version 0.14 includes new work from Werner Kassens about function fittings: https://github.com/SergeStinckwich/SciSmalltalk/wiki/Math-FunctionFit and math accuracy framework: https://github.com/SergeStinckwich/SciSmalltalk/wiki/Math-AccuracyFramework SciSmalltalk project web page is here: https://github.com/SergeStinckwich/SciSmalltalk All the code is available under the MIT licence. We have more than 506 green unit tests and we run a CI job here: https://ci.inria.fr/pharo-contribution/job/SciSmalltalk/ This version should work on Pharo 3.0/4.0 and also Squeak 4.5 (to be confirmed). We are a small community, we are looking for more volunteers to contribute code and documentation. Please join us at : https://groups.google.com/forum/#!forum/scismalltalk -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

Transcript warning in MVC
by Casey Ransberger 17 Sep '14

17 Sep '14

I've been using MVC. It's still buggy, but mostly usable. I thought that if someone just used it for a little while, we'd know where most of the worst bugs are. Currently tracking two issues, one with errors occurring after bringing up context menus (haven't started really digging on that one yet,) and a warning which appears for reasons unknown in the Transcript. This is about the latter. Warning: view contents not found. I spent probably ten minutes sifting through all of the methods containing the string 'Warning:' when the whole string didn't turn up any hits, and I do think I have a lead. It looks like the latter issue is occurring in StandardSystemView>>setUpdatablePanesFrom:, but I'm not sure why yet. The method itself seems pretty straightforward, but for some reason, the block temp aPane is ending up nil. If I'm reading this right, aPane is assigned the value of sending #subViewSatisfying: to a StandardSystemView (in this case, self,) and the argument seems to be a block specifying a constraint, and I may as well paste in the send. aPane := self subViewSatisfying: [:pane | (pane isKindOf: PluggableListView) and: [pane getListSelector == sel]]. This happens right before the nil check, which probably means that the constraint doesn't match whatever #subViewSatisfying: searches (or #subViewSatisfying: is just borked.) View>>#subViewSatisfying: is trivial, and indeed returns nil on no-match. The variable subViews just doesn't have what the method is looking for. I set a breakpoint in order to learn what was actually in there, but alas: it doesn't repro when I'm looking, which is more or less an "all stop" for me on this one. Does anyone know this code well? TIA, Casey

[ANN] Saucers 1.5
by Stéphane Rollandin 17 Sep '14

17 Sep '14

Hello all, Here is the latest version of my little Space Invader game: http://www.zogotounga.net/comp/squeak/Saucers1.5.zip If you run it with another VM than the one provided (for Windows), do keep the ini file else you won't be able to keep your settings and scores. Even if you do not play the game, I encourage you to try it just to appreciate how fluid a morphic app can be. When I started coding I did not expect it could be that smooth. By default, the game is tweaked to be fluid on an older system: the morphs step time is 20 milliseconds. If you have a fast computer, press U (the "CPU intensive" option); this will set the step time to 1, and also animate the background image. As for the gameplay, I let you discover it. At first you can just move the mouse, it's enough to get through the first levels. Stef

Could we have 1 api that work across all of the datish classes?
by Chris Cunningham 16 Sep '14

16 Sep '14

at least adjusting the date portions? We currently have: Date - #addDays:, #subtractDays: TimeStamp - #plusDays:, #minusDays: DateAndTime - #+ and #- I keep getting messed up by which type of object I have, and which method it understands to alter the date portion. Would the community be interested in having these methods spread out to all of the types so that we can have more polymorphic date representations? (and, maybe, even the rest of the protocols?) Or, alternatively, removing some of the options and settling on one standard? -cbc
