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.

Um... I don't know. I didn't have such problems. Maybe try logging out and back? Apart from that I cannot help. :( So hopefully someone who knows what's going on will read this, or you can write to ci-inria mailing list.

That's because you requested "Pharo" and not "pharo-contribution" (should have been the latter).
