Re: [Pharo-users] catching exceptions

by Skip Lentz

Hi, you can use BlockClosure>>on:do:, like this: [ #() atRandom ] on: Exception do: [ 1 ]. Personally, I would check the collection to be empty before calling. > On Nov 26, 2015, at 1:33 PM, abdelghani ALIDRA <alidrandco(a)yahoo.fr> wrote: > > Hi everyBody, > > I know there is some kind of exceptions handling mechanism in Pharo but I cant exactly remember where to find it. > Actually, I would like to execute specific code if atRandomis called on an empty Array or Collection. > I probably can still override errorEmptyCollection but maybe there is another (less radical) way. > And by the way, Would it be quicker to use exception handling then just testing the Collection before calling atRandom. > > Thanks > > Abdelghani

catching exceptions

by abdelghani ALIDRA

Hi everyBody, I know there is some kind ofÂ exceptions handling mechanismÂ Â in Pharo but I cantÂ exactlyÂ Â remember where to find it.Actually, I would like to execute specific code if atRandomis called on an empty Array or Collection.I probably can still override errorEmptyCollection but maybe there is another (less radical) way.And by the way, Would it be quicker to use exception handling then just testing the Collection before calling atRandom. Thanks AbdelghaniÂ

[PhD] Opening for an Internship/PhD on Refactoring

by Thierry Goubier

Hi all, I have an opening on a PhD subject on refactoring for embedded software (start 10/2016), with a 6 month internship before, at CEA List. The PhD title is : 'Reuse of embedded sofware code artefacts by Refactoring' and concern itself with the evolution of embedded software when targetting new parallel embedded platforms or evaluation platforms, and how this can be expressed and supported by domain-specific Refactorings. The internship is about a practical study of the changes undertaken by embedded software code when it is evaluated and re-architectured/optimised in industrial projects undertaken by the laboratory. Both take place at CEA List, LCE lab, in Saclay (SW of Paris), in a laboratory known for its research in simulation of Systems on Chip (SoC), SoC design, compilation for manycores, and neural networks architectures. CEA is a fair employer for internships and PhD students, with a higher than average salary and significant benefits. Interested candidates should contact me. Regards, Thierry Goubier, Research Engineer, CEA List, LCE

Re: [Pharo-users] Pharo RDBMS Support Survey

by Jimmie Houchin

I attempted to answer the survey. Question 6 behaved strangely. It would only allow answers to each question if each answer was a different answer. It would not allow more than one good, or more than one very good, or more than one of any of them. This does not seem like expected behavior. So I stopped and did not proceed. Thanks.

Pharo RDBMS Support Survey

by Esteban A. Maringolo

Hello all, I just created this survey (https://goo.gl/pcc9u8) to collect information about the users of RDBMS in Pharo. Please promote it in the social networks, so I can get as many responses as possible. URL: https://goo.gl/pcc9u8 I'll share the results in a month or before if I get 100 responses. :) Thank you!

Hi, I am generating LaTeX using Pillar and I would like the 'pillarPostExport.sh' to compile my bibliography. So, the default 'pillarPostExport.sh' do: ... pdflatex output.tex pdflatex output.tex ... And I would like it to do: ... pdflatex output.tex bibtex biblio pdflatex output.tex pdflatex output.tex ... Is it possible to override the default LaTeX's compilation script from pillar.conf?

Re: [Pharo-users] Pharo for Data Visualization

by Tudor Girba

Hi, Roassal2 is developed on top of Pharo 5. There is a job that tests the development version of ConfigurationOfRoassal2 on top of the latest Pharo 5.0: https://ci.inria.fr/moose/job/roassal2/ Often, people use the Moose image because it has several other things loaded that are convenient, but that is it. Other than that it should be Pharo 5.
