Sure. Let me know how I can help. I will forward your mail to christelle that manages the mooc for us Siemen did you see the web portal http://rmod-pharo-mooc.lille.inria.fr/MOOC/WebPortal/co/pharo.html (we should add a pointer from http://mooc.pharo.org to it) and also the http://mooc.pharo.org page? because we have the full control on this one. And this is on my todo to make sure that people can get an archive with the complete mooc nicely packaged. Now if you want to help it would be great.

Re: [Pharo-users] The Ultimate Smalltalk Tutorial

by Vitor Medina Cruz

Sorry, many things to do and I wasn't able to look at the Pharo list. *Dimitris:* I really like you idea, and I think it will certainly be better than the videos. I didn't know of Grafoscopio, and I found it interesting too. Do you need someone to test? In latter stages I could try convince some people to try the tutorial too and provide feedback. *Offray:* Thanks for the links, I added them to my read list :) On Fri, Oct 28, 2016 at 6:40 AM, stepharo <stepharo(a)free.fr> wrote: > + 1 :) > > share codevelop and expand :) > > Le 27/10/16 Ã 17:43, Offray Vladimir Luna CÃ¡rdenas a Ã©crit : > > Hi Dimitris, > > Goals 1 to 6 overlap with the ones Grafoscopio.

I think there was Lisp for Squeak (and also Prolog). And port to Pharo should not be difficult.

MOOC TOC cleanup

by Siemen Baader

Hi all, especially Luc, StÃ©phane and Damien, the Pharo MOOC course was fantastic and I use the archived material for reference quite a lot. It is here: https://www.fun-mooc.fr/courses/inria/41010/session01/b116d12e24ec484c98483… But - the English table of contents is in French, and the attached ZIP files need to be downloaded before they can be browsed. It gets quite messy. Would anyone with the required permissions be OK to: - translate the TOC to English - split the ZIP files into separate elements under their respective headlines that can be viewed in the browser or - grant me the permissions to do this work for the community? best, Siemen -- View this message in context: http://forum.world.st/MOOC-TOC-cleanup-tp4921304.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] How does Boolean ifTrue work?

by Dimitris Chloupis

I don't agree with you not agreeing with me, because I never said it would be Smalltalk or Pharo (for those that think that Pharo is not Smalltalk). Yes Strongtalk is a good example, in the case of Pharo you could retain compatibility with Pharo if you followed the example of Hy lang http://docs.hylang.org/en/latest/ Basically Hy is a lisp dialect that runs on top of python , using python's AST library, from one hand it gives you lisp including macros on the other it outputs pure python code which means you can use any python library from Hy and any Hy library from python without any wrapping or extra steps. If you can do this in Python imagine the potential of Pharo. I am itching actually to implement my own lisp dialect in Pharo.

I donât agree with that, if you implement static types or interfaces itâs no longer really Smalltalk.
