Seems that Pharo is a magnet for this kind of project. I've been writing one as well and using it to organize my research notes. Does anyone working on personal info mgmt tools want to talk offline? I expect we're running into some of the same issues, both conceptual and technical. Evan

Aggregation framework in MongoTalk?
by phil＠highoctane.be Feb. 18, 2019

Feb. 18, 2019

Is there anyone using the aggregation framework of MongDb through MongoTalk? It uses the aggregate() command, so I was wondering if this could be supported out of the box or if there is a need for an additional Operation. TIA Phil

Retina support in Pharo
by markm Sept. 20, 2018

Sept. 20, 2018

Hi Is it possible to get Pharo (4 or 5) to run with retina support on OS X? I have tried searching for some answers, but alas could only find a handful of posts from a few years back. Any help much appreciated! Mark -- View this message in context: http://forum.world.st/Retina-support-in-Pharo-tp4895245.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Hi, I'm getting this error while trying to prototype some interface with Spec on Moose 6.0: MessageNotUnderstood: ToolDockingBarMorph>>popUpOwner it happens anytime that I'm using displaying a MenuModel and I go to the menu items. I imagine that the menu item is complaining about a lacking pop up message. How can I solve this? Thanks, Offray

#ast vs. #parseTree
by Sean P. DeNigris May 9, 2018

Why does CompiledMethod understand both? They are in the same protocol, produce the same kindOf result, and neither has a method comment! :/ (Pharo 4.0) ----- Cheers, Sean -- View this message in context: http://forum.world.st/ast-vs-parseTree-tp4893074.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

About validation
by StÃ©phane Ducasse March 11, 2018

March 11, 2018

Hi I read the chapter on validation of the mentoring course book of andres valloud. http://www.lulu.com/fr/fr/shop/andres-valloud/a-mentoring-course-on-smallta… And I love this extension of SUnit. I loved the idea when I saw it for the first time at Lugano (presentation of Leandro Caniglia). I encourage everybody to read it. Now does anybody implemented in Pharo the SUnit extension? I would like to play with it and eventually write a chapter on it for the next book. The idea is so good. Stef

doesNotUnderstand: infinit loop
by Hilaire March 17, 2017

March 17, 2017

Hi, My Pharo4.0 image is in a situation where each MNU exception throw from a DNU result in infinite loop, locking the image, even not breakable with alt+[.]. >From the doesNotUnderstand: message, the "exception reachedDefaultHandler" always returns true, and it results in the execution of the true block, sending again the original message to the original object, repeating a DNU and so on. Any idea how to fix that? Thanks Hilaire doesNotUnderstand: aMessage "Handle the fact that there was an attempt to send the given message to the receiver but the receiver does not understand this message (typically sent from the machine when a message is sent to the receiver and no method is defined for that selector)." "Testing: (3 activeProcess)" | exception resumeValue | (exception := MessageNotUnderstood new) message: aMessage; receiver: self. resumeValue := exception signal. ^exception reachedDefaultHandler ifTrue: [aMessage sentTo: self] ifFalse: [resumeValue] -- Dr. Geo http://drgeo.eu

Moving from Slack to Discord
by Dimitris Chloupis March 9, 2017

March 9, 2017

I have been aware about Discord for some time now , but I never used it because both Pharo and Unreal channels are on Slack. From my small experience with it, it seemed much more superior to Slack with added bonus that is completely free (open source ) and with no restrictions unlike Slack. But something happened suddenly yesterday, I opened Unreal in Slack and it was gone with a notification that they moved to Discord. So I grabbed this opportunity to create a Pharo server you can join here https://discord.gg/F6nAd Discord works as web apps but also you can download as an app for Windows, Macos , iOS and Android. I will be around in Discord because I generally browser Unreal channels. The nice thing about Discord also is that it offers both audio and video chat for free which can work great for Pharo sprints. Anyway there is no harm on testing it.

Coding XPath as Smalltalk
by PBKResearch Feb. 20, 2017

Feb. 20, 2017

Hello I am using XPath as a way of dissecting web pages, especially from Wiktionary. Generally I get good results, but I could get useful extra flexibility by using the binary Smalltalk operators to represent XPath, as mentioned at the end of the class comment for XPath. However, the description there is very terse, and I am having difficulty seeing how to include more complex expressions, especially attribute tests. I have put some of my XPath expressions through the XPath compiler and looked at the output, and out of that I have found expressions which work but look very clumsy. As an example, I have used the fragment: document xPath: '//div[@id=''catlinks'']//li//text()' and found that an equivalent is: document //'div' ?? [:node :x :y|(node attributeAt: 'id') = 'catlinks']//'li'//[:n| n isStringNode]]. (I had to put two dummy arguments in the three-argument block to get it to work.) Is there a more extensive explanation of the use of these binary operators? If not, could some kind person show me the most concise translation of the sample XPath above, to give me a start in working out more complex cases? Many thanks for any help. Peter Kenny
