Line feeds appearing in methods source code?

by Julien

Hello, Itâs the third or fourth time that linefeeds appears in my methods source code while Iâm coding and I do not know whyâ¦ It happens on Pharo 6.1 and on different images. I am on MacOS and I am not copy/pasting code from the outside to Pharo so I do not understand why this happensâ¦ Anyone encounter the same thing?

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

Beware that no mechanism to get back values from Python is defined for now (except if you just want the String representation of those objects, then you can get that if you use atlas). Iâd like to have that but it is not easy. I would like a way to describe how to map Pythonâs objects to Pharoâs objects from Pharo and to have the code to do that in Python side generated automatically but some thinking is neededâ¦ 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 8 janv. 2018 Ã 16:44, Alexandre Bergel <alexandre.bergel(a)me.com> a Ã©crit : > > AI Python libraries may be my first targetâ¦. > I will let you know > > Alexandre > -- > _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: > Alexandre Bergel http://www.bergel.eu <http://www.bergel.eu/> > ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. > > > >> On Jan 8, 2018, at 4:25 AM, Julien <julien.delplanque(a)inria.fr <mailto:julien.delplanque@inria.fr>> wrote: >> >> Happy you find this interesting. >> >> If you have suggestions, just let me know by creating an issue on the repository. >> >> If you create bridges to some Python 3 libraries, tell me as well! :-) >> >> Julien >> >> --- >> Julien Delplanque >> Doctorant Ã lâUniversitÃ© de Lille 1 >> http://juliendelplanque.be/phd.html <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 8 janv. 2018 Ã 01:12, Alexandre Bergel <alexandre.bergel(a)me.com <mailto:alexandre.bergel@me.com>> a Ã©crit : >>> >>> I have just tried Python3Generator.

Happy you find this interesting. If you have suggestions, just let me know by creating an issue on the repository.

Re: [Pharo-users] Is there a way to stop arrays sorting automatically?

by Andy Burnett

Richard wrote >>> I would check this in Pharo, but have so far failed to get it running under Ubuntu 17.10. Squeak _is_ running there, sort of, and the definition of #permutationsDo: in Interval is this code: permutationsDo: aBlock "Repeatly value aBlock with a single copy of the receiver. Reorder the copy so that aBlock is presented all (self size factorial) possible permutations."

Are you sure that Pharo has something different? "with a SINGLE COPY of the receiver" is pretty important. ... <<< Thanks Richard. The Pharo comment is identical. The problem was simply that I hadn't understood what it was - quite clearly - telling me. Now that I understand the problem, the explanation makes perfect sense :-) Cheers Andy
