funny idea Symbol vs. Selector
by stephane ducasse May 14, 2015

May 14, 2015

Hi guys I'm thinking aloud... I was wondering if we could not take advantage of a new class: Selector. MethodDict would only contain selectors and not symbols. I remember that I talked about that with hernan. Stef

Package browser?
by Rob Vens June 28, 2013

June 28, 2013

I am attempting to do the Pharo by Example book, but a package browser (which is used in the examples) is not in the 1.1.1 or 1.2 image. Should I still use categories? If I create a package in Monticello browser I am not able to add classes or anything (not as far as I could see). Just starting out using Pharo, so apologies if these questions are already answered elsewhere.

Actors library
by Alex Schenkman Jan. 24, 2012

Jan. 24, 2012

Hi list, Is there an Actors library already available in Pharo? The part I'm interested in is the asynchronous message passing. If it has been done already, why not reuse? Thanks in advance!

Adding instance variables to existing classes in Monticello
by Nick Chen July 31, 2011

July 31, 2011

Hi I have modified an existing class in the Smalltalk image and added an instance variable to it. I would like to record this change -- added this new instance variable -- in Monticello; that way my team can also pull in the changes and have it work. This existing class is outside of my Monticello package. Is this possible? I have tried following these two threads (~ 2008) * http://forum.world.st/monticello-package-adding-instance-variables-to-exist… * http://forum.world.st/squeak-dev-MC-unload-action-and-postload-actions-td78… by creating a method on the class side e.g. TheObject class>>mcInstallOn: aClassEditor but it does not seem to work. Is this functionality still supported or is there a new way to achieve this? Thanks! -- Nick -- View this message in context: http://forum.world.st/Adding-instance-variables-to-existing-classes-in-Mont… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Hi guys apparently (I suspect some changes we did with Sven I will check), the updates mechanism only download the latest of the issues and skips all the ones in between. So if you want to use 1.4 use for now https://gforge.inria.fr/frs/download.php/28827/Pharo-1.4-14065.zip stef

**Important Please read** Towards First Class Tasks
by StÃ©phane Ducasse July 29, 2011

July 29, 2011

Dear Pharoers I think that we are doing a great work: when I look at the work on the theme, better widgets, network.....Excellent! and thanks. Now we were discussing with Doru about how we as community could coordinate and structure ourselves better to create more energy. Analysis of the current situation: Right now we have individuals doing great projects, sometimes we have a group of people but this is often not visible. Now often happens a bit in ad-hoc way. Because someone ask something, then somebody replies and we integrate the replies. What I would like to see emerging are First Class Tasks with a name a topic a coordinator a group of interested participants, a set of identified clients (because clients are the ones that often make us deliver more), a little agenda, a web presence on the web page If we look at what we have right now that are potential Tasks and really important clients - The Z connection: Network/Socket Coordinator (proposed): Sven Socket: Noury Luc Jannik Olivier Clients: Seasiders, Clouders, - Morphic 2: UI: Alain Gary Igor Coordinator (proposed): ? Presenty framework VoidNullPointer UIBuilder Athens Clients: Moose, Pharo IDE - Pharo IDE: Coordinator (proposed): Doru work around TWM Laurent Nautilus: Benjamin Laurent Glamourous: Doru Damien - OPAL: Compiler tool chain Coordinator (proposed): Marcus? Jb, Jorge, Marcus, Helvetia lukas Niko Schwarz? - Package: Stef, Cyrille Coordinator (proposed): Stephane Client: Nautilus, Doru Moose, - Metacello Dale Mariano Coordinator (proposed): Dale? Client: Stef with the idea of distribution, Torsten don't you want to help here? - Coral: Coordinator (proposed): Damien? Damien, Luc, Adrien, Stef, Client: Damien, Olivier? So what would be good is to have the identification on the web site of these groups. More discussions and concentration with a set of little tasks to be performed We could tag the mails with [Task-UI], [Task-OPAL], have a little visible agenda. What do you think? I think that it is important. Stef

Image confusion
by Jonathan Kelly July 28, 2011

July 28, 2011

Hi, newbie Smalltalker here. Have been playing with Pharo for a couple of weeks - loving it and hating it at the same time! :) So I',m on WinXP and have Pharo in "C:\Pharo 1.2.1 Release". I had thought I'd worked out worked out dragging an image file onto the exe loaded it that image (it seems to work in the main directory with Pharo.exe ... and assumed that would work with cog vm too. So I copied an image into the cog directory "C:\Pharo 1.2.1 Release\cogvm" and dragged it onto PharoCog.exe and have been happily working away. Now I realise looking at modification dates that the image it is actually using is "C:\Pharo 1.2.1 Release\pharo.image" - and confirmed that by actually noticing the window header which says "PharoCog! (C:\Pharo 1.2.1 Relase\pharo.image)" I've filed out my stuff and am going to start again. So, which VM should I be using, and if its cog .. how should I manage images. Thanks Jonathan.

Hi List, How can I use <expectedFailure> togehter with the TestRunner. Testrunner shows the number of expectedFailures, but it always zero, even when I decorate with the Pragma. testShouldFail <expectedFailure> self fail. Thanks in advance!

invalid utf8 input detected
by Jon Hancock July 27, 2011

July 27, 2011

I'm not sure what to expect with UTF-8 encoding in Pharo. Can someone point me to some docs or past discussion? I have tried this today in pharo 1.3: 1 - in a workspace: cnString := ''. 2 - Now I go to Firefox and copy 4 simplified Chinese characters and try to paste this in between the quotes of the smalltalk string in the workspace. 3 - the paste operation throws "Error: Invalid utf8 input detected" The web page I'm copying from is utf-8 encoded. I can copy text from this page and paste into vim or gEdit just fine. The error is thrown by UTF8TextConvertor>>errorMalformedInput I would provide a stack trace...but being new to pharo, I'm not sure how to grab such a report without doing a screen capture. thanks, Jon

Announcer question
by Werner Kassens July 26, 2011

July 26, 2011

Hi, in the pharo book, morphs unsubscribe to an announcer in delete for garbage-collection, but what do i do, when a morph is not explicitely deleted, but its owner? i have mypanelmorph that subscribes to an announcer. it has a tabgroupmorph as its owner, which has a panelmorph as its owner, which has a systemwindow as its owner, which has a model, that knows absolutely nothing about mypanelmorph, but occasionally deletes panelmorph. is there a method in mypanelmorph, where i could put the unsubscription in, that would be called, when panelmorph will be deleted? werner

Using SqueakSource / Metacello "offline"
by jtuchel July 21, 2011

July 21, 2011

Hi there, I need to load packages from SqueakSource into an image that sits on a machine behind a proxy that won't let me download from Squeaksource. I can, however, download packages using the Browser. The problem for me is that ConfigurationOfSeaside30, for example, requires a lot of packages to be loaded first. So I know I can donload all the .mcz files from Squeaksource and copy them to my local PackageCache, but I am looking for a way to find out which ones I need. Is manually extracting the info from the ConfigurationOfSeaside30 class the only way to do that? And how would I go about using ConfigurationOfSeaside30 to use my package cache instead of the online repositories? Any ideas?
