Two suggestions for the new pharo website
by kmo May 29, 2014

May 29, 2014

I think the new pharo website could be improved by the addition of two new pages. Firstly, the site badly needs a "Success Stories" page. The old web site had one of these so presumably that can be added easily. You have to show newcomers that pharo can be used for something real. Look at the/ meteor/ website https://www.meteor.com/main. Meteor isn't even at version 1.0 yet but already boasts a impressive gallery of applications. Secondly, a list of all the packages in the Configuration Browser with a proper description of what they do would be helpful. It would give newcomers the idea that pharo is a comprehensive solution to their development needs. it also would provide newcomers with some kind of guide to the pharo ecosystem - how is anybody supposed to know what Aconacqua or Chalten is meant to do? Pharo has quite an impressive list of add-ons in the configuration browser but what's the point if no one knows what they do? -- View this message in context: http://forum.world.st/Two-suggestions-for-the-new-pharo-website-tp4760379.h… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Do I understand correctly that name is to be understood as inspectorName and so should never be implemented as subclass responsibility? Stephan

Finding methods sending shouldBeImplemented within a package
by Markus Fritsche May 28, 2014

May 28, 2014

Hi, I am working on some NativeBoost bindings to a library. I am organizing my work along the API of a java binding of the same library. As nights go by, I created some methods that I didn't have yet use for as "self shouldBeImplemented", writing the others with test first. What is the easiest way to find all methods sending shouldBeImplemented in my package? Best regards, Markus

3D with Pharo and OpenGL ?
by RIOU Judith May 28, 2014

May 28, 2014

Hy, I'm working at Thales for a year internship and I would like to do some OpenGL demos in smalltalk. I'm searching a demo which shows the capacity to implement 3D drawing with Pharo. Does a demo already available on Pharo 3.0 ? I aim to code my own demo and for example begin with a 3D drawing of the earth (earth texture and arcball camera). Thanks.

Mac keyboard bindings
by darrinm May 27, 2014

May 27, 2014

A number of text editing keys don't work like I expect. For example, Home and End don't do anything and Command-left/right don't behave as they do elsewhere in the system. How can I fix these mappings/behaviors? Thanks. -- View this message in context: http://forum.world.st/Mac-keyboard-bindings-tp4760586.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

storeOn:/readFrom: symmetrical?
by Rick Kitts May 26, 2014

May 26, 2014

Hi. A basic question I hope someone can answer. This works: â cut here --- | stream aInt | stream := (String new:20) writeStream. aInt := 23. (aInt storeOn:stream) = (aInt class readFrom:(stream contents)) â cut here --- This doesnât (generates an error): â cut here --- | stream aTime | stream := (String new:20) writeStream. aTime := Time now. (aTime storeOn:stream) = (aTime class readFrom:(stream contents)) â cut here --- To the question then. Assuming the second case isnât wrong in some fashion I donât understand, is it the case that storeOn:/readFrom: is supposed to be symmetrical for all classes? I ask it that way because there are a couple of Kernel classes where Iâve seen this to not be the case. TIA, âRick

Block Recursion
by Bob Williams May 26, 2014

May 26, 2014

I read that Blocks in Squeak and Pharo, since it was derived from Squeak did not implement true block closures and would not support block recursion. On one count the statement was correct, but not on the other. I tried: | a f | a := 0. f := [ Transcript show: a. (a < 5)ifTrue:[a := a + 1. f value ] ]. f value. a inspect. A Workspace DoIt did not work in Squeak, it failed complaning that the block was being evaluated. In Pharo, it works but with the annoying modal dialog asking to run since f was not assigned a value. If blocks are to be used recursively, a better way must be found to flag but not stop execution. This example points out that porting from Squeak to Pharo is fine, but the reverse might be questionable. bw

Calling an arbitrary method
by sergio_101 May 26, 2014

May 26, 2014

In many cases, an object might have a method (filter, selector, etc) attached to it so that the object can run the correct method.. for instance, an object might have a filterMethod variable with a value 'filterByArtist'.. in ruby, i would do something like: instance.send(filter_method) how would i do that in pharo, and is this a bad idea? thanks! -- ---- peace, sergio photographer, journalist, visionary #BitMessage BM-2D8VWUJSS41RFKh1ec83preVabHrnniExa http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Versionner: Specifying un-configured packages as dependencies
by Johan Fabry May 25, 2014

May 25, 2014

Hi all, Iâm using Versionner to make a ConfigurationOf and things are working quite well (thanks for that!) until I want to add the Roassal2Spec package as a dependency. The dialog box only shows packages with a configuration, and Roassal2Spec does not have one. Itâs just one package. How can I add this guy to my configuration? Thanks in advance, ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile
