Searching for similiar projects

by Jigyasa Grover

Hello :D I am a newbie in Pharo and have started to build my first application i.e. an offline text search application namely *searchQuick* which returns the list of file titles from the pre-loaded text files present in the resource folder when a string is searched for. You all are welcome to fork the code (https://github.com/jig08/sQuick_new) , try the infancy application and send in suggestions. Further, I would like to request to put up my application on the CI Automated Build server for Pharo. I have already registered on INRIA and my request to join 'Pharo Contribution' has also been approved. Further, I am searching for similiar projects as sQuick so that it would be easier to put for automated build using the existing build. It would be great if someone could guide me how to find similiar projects or exisiting templates. Regards Jigyasa

Saving image sometimes corrupts it

by Jan BlizniÄenko

Hello I come with another probably-only-mine-windows-related problem which I am unable to reproduce from a clean image. I use latest image 50170, latest (9th July 2015) Windows VM, Windows 7 64bit. So there is my vague description: When I load some project, modify it few times and save it, then SOMETIMES (seems random to me) when I try to open this saved image, it immediately crashes VM and does not even produce crash.dmp file (well, it creates it, but empty). For example, I have such image... I save it, do not close it, try to open it, crash, save it again, try to open it, it runs, save it again, close, try to open it, crash. Without any change inside the image by my hand. I tried doing something similar with clean image, but it never corrupted it. I am unable to open such image even on my Linux machine. It at least generates output when segmentation fault happens: http://pastebin.com/KLry40Hu HDD I am saving it to does not show any signs of damage, everything else is working (and saving) just fine. Here is such crashing image: http://www.mediafire.com/download/h5vhh7c40cl1w15/Pharo+5.0+%28beta%29-5017… and here is the same image saved again which runs fine: http://www.mediafire.com/download/86djppsn1ds3c0o/Pharo+5.0+%28beta%29-5017… However, when I open this "ok" image in linux, it causes segfault too. I tried also opening working image in VM marked as stable (2015-09-24), then I saved it and there was the same problem. This is probably all I know about it, although I am aware that it is not much, but I am in the dead end and this problem is really huge for me. I am on ESUG so if you are here too and think you might be able to help, I can show it to you personally. Jan BlizniÄenko

SubscriptOutOfBounds: 0 in blocks evaluating nil

by Jose San Leandro

Hi, I'm experiencing an issue when using whileFalse:, in Pharo 4. I've just looking for opened bugs in pharo.fogbugz.com but I don't see any matching my problem, apparently. In the following example, I get a SubscriptOutOfBounds: 0. Object subclass: #WhileFalseIssue instanceVariableNames: 'myFlag' classVariableNames: '' category: 'MyTests' WhileFalseIssue>>attemptUninitialized [ myFlag ] whileFalse: [myFlag := true ]. ^ myFlag. WhileFalseIssue>>attemptInitialized myFlag := false. [ myFlag ] whileFalse: [myFlag := true ]. ^ myFlag. Calling attempt like this: WhileFalseIssue new attemptUninitialized. launches the debugger with "SubscriptOutOfBounds: 0" (see attached screenshot), whereas WhileFalseIssue new attemptInitialized. works fine. Should I file in a bug in fogbugz? I will try with Pharo 5. Kind regards, Jose.

PharoJS

by Andy Burnett

Is anyone experimenting with PharoJS? I managed to get the page with the core javascript functions to load - as localhost - but I couldn't get any of the actions in the workspace to have any effect on the web browser console. Has anyone had any success? Cheers Andy

That could solve the problem with your example: passing array of objects of *same* type. But in general, it is not what C variadic function(s) standing for. Because they stand for any number of arguments, of any type. In C, since all program is compiled statically, compiler knows the number of passed arguments and their types through compiling each particular call site(s) to variadic function. Which means that in fact, you are still supplying all information needed by compiler *before* run time. In variadic functions, you can pass any arguments of any type, but for converting each of them, you must tell NB what kind of marshaller should be used for it , which means, that it is impossible to know before run time, since you cannot know how many arguments you may pass, not speaking about their types. > Thanks, > > Matthieu > > > -- Best regards, Igor Stasenko.

Re: [Pharo-users] Coverage tools

by Alejandro Infante

Hapao does work at method level, but without reflectivity going further to AST level is not possible. Alexandre is going to show in ESUG an integration of Hapao reports with EclEmma plugin for Jenkins and also a Roassal visualization of the Hapao report in the browser to be attached in Jenkins build.
