Re: [Pharo-dev] String>>#adaptToNumber:andSend:

by Florin Mateoc

Hi Stef, I think this one's easy, especially for Pharo. Since apparently it was Etoys, not Morphic, that was or is using the strings and numbers mixed arithmetic, and Pharo does not care about Etoys, the arithmetic protocol (the operators plus the adaptTo...:andSend: methods) should simply be removed from String. While I did not perform any extensive testing, I did remove them in a Squeak (Morphic) image and nothing seemed to break. Even for Squeak, I think the solution should be the same and Etoys should be fixed to not use this particular hack. Florin On 5/26/2015 2:20 AM, stepharo wrote: > Hi florin > > I agree with you.

translateBy: vs translatedBy:

by Serge Stinckwich

In Pharo 4.0, there is a Rectangle>>translateBy: aFactor method. The same method in VW is called translatedBy: In Pharo, there is also a translatedToBeWithin: and translatedAndSquishedToBeWithin: and scaledBy: Just to be consistent, this is maybe better to use translatedBy: instead of translateBy: ? -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

Re: [Pharo-dev] Gofer upgrade error

by Esteban Lorenzano

Hi, that will not work. and it will never work like that sadly. You are trying to use gofer as apt-get, and thatâs not how it worksâ¦ you cannot just update packages to have a working image with newer versions. The way pharo should work is: - there is the update process (world menu, system, update system) who will try to update the pharo system. That means not external project (like for instance seaside) will be updated. Please notice that this process is currently BROKEN, so you cannot try it now. We will restore it, but so far no time to work on it (also, is not top priority because is not of frequent use: most people needing to update just download an image and start over again, which is super easy to automatise using zeroconf and command line scripts). - you can update your installed projects by downloading newer configuration versions and applying them. But again, more frequent is to just doing it in a newer image. the reason why this is not really used is because pharo (smalltalk) extensibility is powerful but complicated to manage, due the amount of overriding methods, etc. cheers, Esteban > On 25 May 2015, at 15:54, Leo Paniceres <lpaniceres(a)gmail.com> wrote: > > âHi Stephan > I'm trying to have my image updated to the last version of each package that I'm using. > I'm trying first: > Gofer upgrade (to update Gofer) > and then to update: > Gofer gofer update (also have an error)â > > âAny advice to have all my third party packages updated?â > > âThanksâ > > > > > ------------------------------ > > Message: 4 > Date: Mon, 25 May 2015 08:53:26 +0200 > From: stepharo <stepharo(a)free.fr <mailto:stepharo@free.fr>> > To: Pharo Development List <pharo-dev(a)lists.pharo.org <mailto:pharo-dev@lists.pharo.org>> > Subject: Re: [Pharo-dev] Gofer upgrade error > Message-ID: <5562C6E6.901(a)free.fr <mailto:5562C6E6.901@free.fr>> > Content-Type: text/plain; charset=windows-1252; format=flowed > > Hello leo > > Thanks for your feedback.
