if i have an OrderedCollection called people.. if i have a million ordered pairs in there, and i wanna see af any one of them (hasTenBucks = true). i don't want to iterate all of them, i want to stop when i find that one hasTenBucks.. so in something like: people do: [ :person | (person hasTenBucks) ifTrue; [break out of loop] ] ideas? thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Why do you mean missing in pharo? When you load chronos this is not there.

[Pharo-project] Fwd:Dr.geo en Arabe

hanks Ahmed! A request. Is it possible to have Arab language under Pharo? Hilaire -------- Message original -------- Sujet: Dr.geo en Arabe Date : Sat, 06 Nov 2010 13:29:40 +0000 De : Ahmed Mansour <atphalix(a)inbox.com> Pour : Hilaire Fernandes <hilaire.fernandes(a)gmail.com> Bonjour Hilaire, Si joint la traduction de Dr.Geo II en Arabe, j'ai testÃ© uniquement sous Etoys vu qu'il a le support de Pango (indispensable pour le rendu de script complexe), est-t-il possible d'ajouter le support de Pango Ã Pharo dans une version prochaine?

I think it could be of great value for Pharo, and an enabler for evolution. So, I did a request to Esug, to deliver this, naming it "SimpleMorphic", ready to run in Pharo, instead of Morphic 3. Esug approved it, and I thank them for this. SimpleMorphic is the result of this. I started by extracting the Morphic in Cuis. This was not trivial, as I had to think carefully where to draw the line between what I'd migrate to Pharo and what I'd use from Pharo. Then I adapted it to some differences between Cuis and Pharo, and also tweaked Pharo to enable using alternative UIs. I worked about 80 hours on this and delivered this week. > > After all this, I think it is fair to say that Esug sponsored Cuis as SimpleMorphic is part of it.

Pavel can you point our such initializations problems so that we fix them.

[Pharo-project] Morphic 3, Cuis, Simple Morphic and Esug's sponsoring
by Juan Vuletich Nov. 7, 2010

Nov. 7, 2010

Hi Folks, All what Stef said wrt these issues is correct. I just want to (perhaps) make some detail clearer. Esug agreed to sponsor Morphic 3 about one year ago. At that time I expected to have a working and usable system by the end of this year. This is not going to happen. Main reasons are: 1) I underestimated the effort. 2) Inflation and other issues meant I needed to make more money that I was currently making. So I had to reduce the hours I devote to volunteer work to spend them in paid work. 3) I failed to get sponsors for this project outside the Smalltalk community (although I did try). 4) Some of the ideas in Morphic 3 are novel enough that I need to protect them from being patented by others from, before disclosing them. I don't like software patents, so I believe the best way to do this (and get more people to know these ideas) is to submit a paper to a journal such as ACM Transactions on Graphics. This will obviously require additional time. So work on Morphic 3 is not stopped, but right now it is paused. It seemed to me that instead of just telling Esug "I'm sorry, but you'll get nothing by the date I promised results", I could do a more practical, down to earth contribution to the Smalltalk community in return for Esug's support. I believe that many in the Pharo community share my opinion that the current Morphic implementation is obfuscated, that it is too hard to write applications with it, and that it is too hard to fix bugs and evolve it. The Morphic implementation in Cuis is the main result of many (I guess about 6) years of part time work on simplifying the system. I think it could be of great value for Pharo, and an enabler for evolution. So, I did a request to Esug, to deliver this, naming it "SimpleMorphic", ready to run in Pharo, instead of Morphic 3. Esug approved it, and I thank them for this. SimpleMorphic is the result of this. I started by extracting the Morphic in Cuis.

Then I adapted it to some differences between Cuis and Pharo, and also tweaked Pharo to enable using alternative UIs. I worked about 80 hours on this and delivered this week. After all this, I think it is fair to say that Esug sponsored Cuis as SimpleMorphic is part of it. I hope this helps and does not add confusion. Cheers, Juan Vuletich
