Re: [Pharo-users] [ANN] Python3Generator and MatplotLibBridge

I guess the hardest part will be to define the 1 - 1 mapping between Numpy and PolyMath APIs, no? I mean, how can you ensure that features using Floats will behave exactly the same in Python and Smalltalk for example?

Hello Serge, Do you mean pieces of code you wrote in Python using Numpy that you want to transform to Smalltalk code using PolyMath? Itâs kind of the other way around of this project. :-) Julien --- Julien Delplanque Doctorant Ã lâUniversitÃ© de Lille 1 http://juliendelplanque.be/phd.html Equipe Rmod, Inria BÃ¢timent B 40, avenue Halley 59650 Villeneuve d'Ascq NumÃ©ro de tÃ©lÃ©phone: +333 59 35 86 40 > Le 10 janv. 2018 Ã 14:07, Serge Stinckwich <serge.stinckwich(a)gmail.com> a Ã©crit : > > Thank you Julien for this very interesting piece of code. > What I need at the moment is a way to transform semi-automatically Numpy code to PolyMath code ... > > On Mon, Jan 1, 2018 at 8:22 PM, Julien <julien.delplanque(a)inria.fr <mailto:julien.delplanque@inria.fr>> wrote: > Hello, > > My new year main resolution: stop keeping my side-projects for me. > > Itâs been like 1 year that I created these two projects, one coming from a refactoring of the other. > Now it is time to take time to announce them. > > I initially come from Python world and during my bachelor & master, I really liked to use matplotlib to plot data using Python. > > So I wanted to be able to use this Python module from Pharo.

Thank you Julien for this very interesting piece of code. What I need at the moment is a way to transform semi-automatically Numpy code to PolyMath code ...

Re: [Pharo-users] How to I setup Bloc?

by Aliaksei Syrel

Hello Photon, I have literally no idea where you found this paper but it is years old. Could you try to install it according to instructions on Bloc GitHub page: https://github.com/pharo-graphics/Bloc You might also want to try a MemoryGame tutorial: https://github.com/pharo-graphics/Tutorials Let me know if something does not work. P.S. Could somebody with access rights delete this page: https://ci.inria.fr/pharo-contribution/job/PharoBookWorkInProgress/lastSucc… ?

Google Summer of Code 2018 with Pharo Consortium

by Jigyasa Grover

Hello Pharo-ers ! On behalf of the community, I would like to thank each one of you for their significant contribution in the previously concluded *Google Summer of Code 2017* with *Pharo Consortium*. We aspire to take-off on a long flight after this successful stint by applying to participate in the upcoming *Google Summer of Code 2018*. As many of you might know, Google Summer of Code is a global program focused on bringing more student developers into open source software development. Students work with an open source organization on a 3 month programming project during their break from school. Read more about the program here: https://summerofcode.withgoogle.com/ The deadline for organisations to apply is January 23, 2018 which is fast approaching. As an open source evangelist and a Pharo developer, I would like to invite all the experienced members to be a part of the "GSoC 2018 with Pharo Consortium" Team and mentor students. Propose fresh ideas for projects which shall help improve Pharo or volunteer to mentor any of the existing one (Listed here: http://gsoc.pharo.org/) To add your own project idea to the list, visit http://gsoc.pharo.org/#adding-a-proposal Looking forward to an appreciable representation from the Pharo community. Best regards Jigyasa Grover Pharo Consortium Org Admin, Google Summer of Code 2017 [hidden email] -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

How to I setup Bloc?

by Photon

Hello I have trouble with Bloc. I tried to install it like this as i read it in a paper on Bloc but then this does not work because there is no suchclass, istall is send to nil. I had also trouble with the tutorial earlier. I could not see anything in the preview altho the code was aparrantly fine. I really like to do something with bloc but i cant even set it up properly. Please help me. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
