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

Postmark email library
by Francois Stephany Aug. 31, 2013

Aug. 31, 2013

Hi guys, I've made a simple wrapper around the Postmark API. It lets you send emails without dealing with a SMTP server. You can read about it here: http://developer.postmarkapp.com/developer-libs.html http://developer.postmarkapp.com/developer-build.html and there: http://articles.tulipemoutarde.be/send-email-from-pharo-with-postmark It's pretty simple and naive implementation but it gets the job done. I'll add email attachements when I will need it. Francois

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.

Adding OAuth & OpenID support to Pharo
by Andy Burnett Dec. 20, 2012

Dec. 20, 2012

Hello, Now that we have added Websocket support to Zinc, I would like to move forward and add OAuth & OpenID. Sven Van Caekenberghe, and Jan van de Sandt, have put together a proposal, which my company would like to fund. If anyone feels that they would benefit from this - commercially - and would be happy to make a contribution to the development costs, please shoot me an email. All contributions are gratefully received. Cheers Andy

[OT] RTalk
by dimitris chloupis Oct. 30, 2012

Oct. 30, 2012

I found this http://www.jarober.com/blog/blogView?showComments=true&printTitle=IM_98:_Rt… ,about RTalk , that is not only smalltalk run on top of JVM but almost the entire environment.Â The problem is that I cant seem to be able to find via google any site that contains the source code or something I could use ? Does anyone know if there is any official website for RTalk ? It looks quite promising and I would like to give it a try.

Zodiac long-term streaming
by Sean P. DeNigris Oct. 28, 2012

Oct. 28, 2012

My image is connected to an ssl streaming server with Zodiac... Okay, right off the bat, how cool is that?! Thanks, Sven! Anyway, using "ZnClient streaming: true; post: 'https://', url contents: data", I have a ZdcSecureSocketStream waiting for more data. Is there a way to specify "no timeout"? Since the connection is only good for 24 hours, I was thinking to just set the timeout to be a little longer than that, but I was curious.

garbage collection questions
by Paul DeBruicker Oct. 26, 2012

Oct. 26, 2012

1. Is there a wiki entry about the GC somewhere that provides advice about how to tune the GC using #setGCParameters? 2. If I have two objects with accessors: Object subclass: #ObjectA instanceVariableNames: 'objectB' classVariableNames: '' poolDictionaries: '' category: 'Temp' Object subclass: #ObjectB instanceVariableNames: 'objectA' classVariableNames: '' poolDictionaries: '' category: 'Temp' and create an instance of each in a workspace and then set them up: |a b| a:=ObjectA new. b:=ObjectB new. a objectB: b. b objectA: a. and close the workspace then those instances of ObjectA & ObjectB will never be garbage collected, correct? Its my understanding that I'd need to nil out the instance variables of both instances to have them GCd as they both refer strongly to each other. Is that right? 3. How can I learn when an incremental or full GC run will happen? Is it dependent upon on the size of new or old memory or the overall size of the image or ... ? It seems like putting a #halt in a random spot could easily lead to a stuck image. Thanks for your help Paul

Regex search and replace with groups
by Davide Varvello Oct. 25, 2012

Oct. 25, 2012

Hi there, I'd like to remove a slash from a string like this one: 'abc123/456def/ghi' The resulting string should be 'abc123456def/ghi' that is only slashes surrounded by numbers should be removed. I tried with regex and group, using something like: 'abc123/456def/ghi'copyWithRegex: '(\d)/(\d)' matchesReplacedWith: '$1$2' but of course it doesn't work, dollar sign doesn't identify the group, sigh. Have you any suggestion?

Nautilus plugin to add chasing implementor browsing
by peter h meadows Oct. 24, 2012

Oct. 24, 2012

This is my first attempt. Did I do it right? (I'm still learning). It works in Pharo 2.0. To test; load this code in monticello: MCHttpRepository Â Â location: 'http://ss3.gemstone.com/ss/ChasingNautilusPlugin' Â Â user: '' Â Â password: '' Open the Nautilus Plugins Manager (by clicking the drop down arrow at the top right of a nautilus window). Add ImplementorsChasingPlugin. Then open a new nautilus window and look at a method. Nautilus should now show you a list of all the message sends by that method. Clicking on those shows you a list of the places they are implemented. Is there something with this functionality already in Nautilus? I couldn't find it. Cheers.

full Text diplay in a ListMorph?
by Dale Henrichs Oct. 21, 2012

Oct. 21, 2012

I would like to display Text objects in a ListMorph, but from reading the code (and experience) it appears that the display code for lists, makes the text attributes homogenous across the whole line being displayed ... so any changes to emphasis or color in the Text object are lost ... That seems to be a shame... I've spent a bit of time this morning trying to use a Paragraph for display in the list morph, but my ninja morph skills are sadly lacking:) and I'm failing miserably,,, So, has anyone else encountered and conquered this particular problem? If you tell me that it is available in 2.0, I suppose that is a good enough answer, but it would be nice if there was Pharo1.4-based solution... Dale

Spec: Dynamically replacing widgets
by Sean P. DeNigris Oct. 21, 2012

Oct. 21, 2012

I'm building a wizard, so I want the page widget to be replaced by the next one when the user clicks "Next". I tried (in the container model, in the callback for the next button): pageModel := PageModel owner: self. self needRebuild: false. self buildWithSpec. It "worked" in that it replaced the page, but it looked really weird... the vertical spacing of the controls was off and all the text widgets were invisible, even though they were there and working if clicked on.

Text Diff
by Luc Fabresse Oct. 18, 2012

Oct. 18, 2012

Hi All, I tried to do a text diff using DiffMorph. But if compared strings contain CR character, the display seems not be accurate. Example: s1 := 'ab', String space, String cr, 'd', String space, String cr, 'ef'. s2 := 'ab', String cr, 'd', String cr, 'ef'. (DiffMorph from: s1 to: s2) openInWindow. In this example, d (on line 2) is highlighted while it should not IMHO. I track this until (a DiffMorph uses a TextDiffBuilder): TextDiffBuilder>>buildPatchSequence ^Array streamContents: [ :stream | self patchSequenceDoIfMatch: [ :string | stream nextPut: #match -> (string copyWithout: Character cr) ] ifInsert: [ :string | stream nextPut: #insert -> (string copyWithout: Character cr) ] ifRemove: [ :string | stream nextPut: #remove -> (string copyWithout: Character cr) ] ] My question: why ignoring Character cr? Should we change it? #Luc

Hellp + PostgreSQL Connector
by roberto.minelli＠usi.ch Oct. 18, 2012

Oct. 18, 2012

Hello, I am Roberto Minelli, a PhD student in the REVEAL research group at the Faculty of Informatics of the University of Lugano. I am exploring Smalltalk, and Pharo, for the first time and I am open to suggestions and tips & trick. Shortly I would like to work on something concrete to get in touch with Smalltalk. One of the things I am interested in, is retrieving entries from an existing PostgreSQL database. To this aim it would be great if some to you could point me in the right direction. ;) I also heard that there are some very cool "extensions" to the Pharo IDE (i.e., code completion, code browsing, etc). I would be glad if some of you could help me discovering all these cool features of Pharo! Thanks in advance, Roberto M.

OrderedCollection detect: <- exception if not found?

i had a problem earlier, thinking that if i did a detect: on an ordered collection, and the item was not found, i would get back nil. it turns out that it throws an error.. to get this to work, you use: detect:ifNone: my only question is... why is this so? what is the motivation behind throwing an error rather than returning nil? i guess i would like to understand the 'smalltalkiness' about this, just in case i run into something like this in the future.. thanks! -- ---- peace, sergio photographer, journalist, visionary 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

subscribe on system change
by Miguel Enrique Campusano Araya Oct. 16, 2012

Oct. 16, 2012

I want to do some logic when there is a change on the system, like when a new class is loaded or when a method change. I don't want to put this logic explicit on the methods of the system who do that. I would like to know if i could subscribe to those special events (method change, new method, changes on a class and so on) so I can do what I want outside those methods. I heard about the Announcements but I don't know if Announcements could help with this problem. Can anyone give me some highlights to do those things? Thanks!

Now, when I try to load this configuration, it fails to properly load the package BBB (there are some missing classes) with this msg: *This package depends on the following classes:* * A class in package AAA* *You must resolve these dependencies before you will be able to load these definitions: A class in package BBB.* It seems that there is a way to load packages in a linear order ( http://code.google.com/p/metacello/wiki/FAQ#Controlling_Package_Initializat…) However, my project defaults is already set to linear and after reading this post my problem is not resolved. Can anyone help me how I can enforce package AAA to load before BBB? tx, usman

Bag of Permutations

the way the facebook authorization scheme works is as follows: 1. on the first go round, facebook sends a POST with some data in it that needs to be parsed to pull an authorization code out of it. 2. if the app isn't authorized, i need to redirect to an authorization dialog to so that the user can authorize my app. 3. once the user does that, my app receives an oauth code, and i am on my way. i have everything working, except, i am not sure where to store the authorization code.. in my main component's renderOn, it looks to see if the a instance variable 'oauthToken' is set. if not, it renders some javascript that is really just a redirect to the facebook authorization screen. once the app is authorized, 'oauthToken' is set to the correct value. then, the authorization dialog sends the request BACK to the root url.. everything works correctly..BUT.. on the second time back, the redirect from facebook, it looks like it starts a brand new session (there is a new instance of the main component created). i was hoping that this would all be one session, and that i could just set an instance variable once, and not even touch the session, but i don't think this is going to happen. plus, it looks like i will be firing up a new session on return anyway, so what i have saved in session will be lost. anyone have any ideas on how to cleanly persist this variable after facebook's redirect? thanks! -- ---- peace, sergio photographer, journalist, visionary 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
