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

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

Mea Culpa
by horrido Aug. 14, 2016

Aug. 14, 2016

Okay, so far, I've made two mistakes. First was my lack of sensitivity to cultural differences around the world. Now that I know better, I shall do better. Second was my failure to distinguish between different subgroups within the Pharo forum. The reason I chose Pharo forum to discuss my campaign was the fact that it is the most active Smalltalk forum there is. People who are interested in Smalltalk join the most active forum generally, and this includes not only Pharoers, but people from ESUG, Squeak, Cincom, Amber, Redline, etc. So, for example, when I appealed for contributors to the Redline project, I should've distinguished the target audience as those groups other than Pharoers. This was my failure and I own up to it. It is unfortunate that I must use the Pharo forum for this purpose. The Smalltalk community is so terribly fragmented that there is no universal Smalltalk forum to address, at least, none that is actually *inhabited*. Without the ability to address the largest number of Smalltalkers, the SRP cannot make any progress. I'm sorry, but I have to be blunt. If anyone can offer a practical alternative, I'd like to hear it. Otherwise, the SRP has only two choices: 1) Continue what it is doing on the Pharo forum, and be mindful of which group(s) I am addressing. 2) Fold up the campaign and leave the destiny of Smalltalk to the Fates. Without the ability to reach out to Smalltalkers everywhere, I am hopelessly disadvantaged.

Tables in Pillar

April 3, 2016

How is one doing a cell with content wrapping on multiple lines? With the | X | Y | abcd | some very long text that should be wrapping but apparently doesn't. So it is very annoying when one attempts to describe a long thing, which is one purpose for a table. I get one single line for each entry. How to do that? TIA Phil

World lastKeystroke and openInWorld: aPasteUpMorph
by Markus Schlager Feb. 20, 2016

Feb. 20, 2016

Hi, I'm using pharo to teach smalltalk as first 'real' programming language at school. With older versions of pharo I was glad that my pupils could track keystrokes so easily by evaluating World lastKeystroke. With Pharo3.0/4.0 this only returns '<down>' independently of any keys I'm typing. f := PasteUpMorph new openInWorld. f takeKeyBoardFocus. f lastKeystroke. Is returning the empty string. Hence, my question: Is lastKeystroke broken, or how is it meant to be used now? Second problem: In older versions of pharo this would work: f := PasteUpMorph new openInWorld. b := EllipseMorph new. b openInWorld: f. But with Pharo 3.0/4.0 the last line raises an error: MessageNotUnderstood: PasteUpMorph>>startSteppingSubmorphsOf With f := WorldMorph new openInWorld. b := EllipseMorph new. b openInWorld: f. pharo freezes. So: How is openInWorld: meant to be used? Markus

Rectangle center rounding
by Jan BlizniÄenko Sept. 22, 2015

Sept. 22, 2015

Hello I came to problem with Roassal which originates in Rectangle class. Although rectangle holds its points (origin and corner) in float (not rounded) numbers, the Rectangle>>#center method rounds it down to integers. It causes wierd behavior in Roassal where moving elements in some ocasions are "jumping" to all directions like a jelly. I understand it is for performance reasons, but I think this optimisation is not on the right place. Rectangle origin: 0.9(a)0.9 corner: 3@3 just does not have center 1@1, it is way too far from the real center. Shouldn't the rounded method be separated as for example roundedCenter or something like that to eliminate the confusion?

New Pharo based solution in the wild
by Esteban A. Maringolo Sept. 8, 2015

Sept. 8, 2015

Hi all, After one year of negotiations (demos, quotes, etc.) and a couple of months of development, by the end of December we released a pilot version of our pharo based solution. The solution consists of a native mobile app (Android), with Pharo 2.0 servers, using Seaside for the web UI, Seaside-REST for the mobile app API and Zinc Websockets to certain "live" features of the web. The persistence is GLORP using the native PostgreSQL driver. I can't disclose much more about the customer or the solution yet, it is a private solution for a multinational consumer goods company operating in Argentina. But I can comment on the numbers: * The pilot will end in ~40 days * It involves 50 mobile users of the Android app using it daily. * An nginx frontend for static files and http proxying to the pharo app servers * Two pharo images as servers, one for the web interface, and one for the REST API. The image is the same, they work as two separate app servers to make use of each server and for improved reliability (I don't want the seaside failures, which has been none yet, to affect the REST API). * Everything running in DigitalOcean droplets based in NYC (they add ~180ms of latency from here but their price/value equations is unmatched). Some performance numbers: * The Pharo server uptime has been no less than perfect, the first 10 days with uninterrupted uptime. Only shutdown to upgrade the image (yesterday night). * The load is minor, with peaks of ~30 concurrent mobile users during a few "business" moments of the day, the server never passed 15% of CPU use. The disk I/O is also small, but the database is small too (growing daily). If the pilot succeeds the plan is to extend the user base to ~1000 mobile users. But some water must pass under the bridge before thinking of that. And if it ever happens, it is going to be gradual. Some anecdotal info I quit my Smalltalk full time job at InfOil (after 9 years of employment) to dedicate 100% to my new company. So I'm betting big on this. By now I'm the sole Smalltalk developer (devops?) of the company. Time has never been more scarce than nowadays. Why Pharo? * Because it is the best open source Smalltalk ("inspired") out there. * Because I have 10+ years of experience with Smalltalk I can't throw away in the context of rapid prototyping and business domain modelling (emphasis on this). * It was a key advantage during the negotiations, we could show a wireframed live app even before our competition prepared a PowerPoint presentation. The development process with Pharo has been rudimentary, only Monticello packages and a couple of workspace scripts to provision new images. I still can't get my head around Metacello. But honestly I haven't dedicated as much time as it needs to be learnt. Having used VAST ENVY's ConfigurationMaps successfully in the past is a proof I can learn Metacello. During the last years at InfOil we were using git with Dolphin Smalltalk, with CI after every git push to the main repo. This was also linked with our issue tracking system, in order to know in which build a certain issue was fixed. We used Dolphin's PAX's files (CVS friendly), Gitlab, JetBrain's TeamCity and YouTrack I'd like to do the same using Monticello's FileTree, BitBucket and JIRA (CI server to be defined). Hopefully with some time, I'll be able to dive deeper into this. My learning of Pharo tooling hasn't been straightforward, but maybe because I'm old and spoiled with other Smalltalk dialects (VSE, VAST, Dolphin). I was managing the Android code (java) with git branching and merging way before I learnt how to use Monticello. Managing the code (files) was the only advantage of working with Eclipse/Java. Everything else was a burden compared with Pharo. I wanted to share my experiences through a blog, but haven't had time to set it up as I'd like, and by now this email is going to be all I can share. After the pilot, we can talk about reporting a success story for Pharo. I felt like this during the last week: http://devopsreactions.tumblr.com/post/68251866244/successful-deployment-at… Best regards, Esteban A. Maringolo CTO (aka DevOps), http://trentosur.com

Mongo lost references - bug?
by Sabine KnÃ¶fel Aug. 17, 2015

Aug. 17, 2015

Hi Esteban, I found a problem in mongo/voyage and I have reduced and extracted it for repro. I ask for your opinion if this is a bug. If you file in the code below, the method >>testDemo creates a simple model: Paper has 1:1 reference to Planet. Paper has 1:1 reference to Star. Star has 1:N reference to Planet. Star has 1:1 reference to Paper. Planet has 1:1 reference to Paper. If you run >>testDemo, you see that the model which was created is ok with all its references. (self assert: thePaper planet = thePaper star planets first.) ==> ok If you reset the repository and load Paper from database with Paper select all and make the same check, the references are lost. VORepository current reset. theReloadedPaper := Paper selectAll first. self assert: theReloadedPaper planet = theReloadedPaper star planets first ==>not ok But if you remove the comment within >>mongoPlanets which leads to sending a message to the newly loaded object, then it works. write: [ :star :planets | star planets: (planets "select: [:each | each someMethod]") ]); Do I have to send a message to each of the instances after loading? I think no. If I did not understand correctly how to use voyage, please tell me.

I tried to point it to libjli.dylib, which looks similar, but that does not seem to work: JNIPortJNIInterface libraryFile: '/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/MacOS/libjli.dylib'. Can anyone point me in the right direction? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

Create maps from an SVG file in Roassal

Hi there, I'm trying to import an SVG file describing the provinces of Belgium in Roassal. I've cleaned an SVG file found on wikipedia and trying to import it. I'm trying to imitate the way it is done with Countries. So: RTMapBuilder class>>provincesOfBelgium > ^ #(#antwerp #brussels #eastFlanders #flemishBrabant #hainaut #liege > #limburg #luxembourg #namur #walloonBrabant #westFlanders) > and implemented to corresponding SVG paths. Here's one example: RTSVGPath class>> antwerp > ^'m 177.419,25.0693 1.379,-3.5593 -2.986,-1.3778 -3.33,0.5742 > -0.114,-3.1001 -4.019,-4.0187 1.492,-5.9704 -2.181,-2.8706 -1.952,-0.2298 > -1.034,-1.2628 -2.411,5.1667 -3.673,3.7892 -3.101,-2.067 -5.396,1.378 > -2.068,-1.8371 4.479,-0.9188 0.345,-5.1667 -6.2,-2.1815 -4.938,5.741 > 0.114,2.8704 -8.611,-0.574 1.264,-5.5112 -5.397,0 -6.43,3.4444 1.263,4.5929 > 2.411,2.7555 -1.492,2.6409 -4.478,-0.6891 0.115,-2.7555 -6.43,0.3443 > 0,2.4112 2.296,0.5743 -0.345,5.5112 3.904,1.0336 -3.1,3.3295 3.056,7.4863 > 0.504,5.9475 -7.923,0.2296 -2.985,3.1002 1.722,1.837 -0.114,3.5595 > 2.889,0.4893 3.352,-0.9423 7.038,4.5375 3.704,-0.5553 1.759,1.7593 > 3.149,-1.7593 4.075,2.1297 2.963,-3.6118 11.112,-1.7592 0.092,3.3337 > 11.576,-3.6113 1.204,-3.0562 5.001,-0.8332 2.129,-3.8894 4.723,-0.7409 > 0.741,-1.9448 2.223,0.8336 1.481,-0.8336 0.186,-4.9079 -4.075,-2.0373 > 1.605,-5.4063 z'. Very naively, I've tried: provinceExample > "self new provinceExample" > | b | > b := RTMapBuilder new. > b countries: RTMapBuilder provincesOfBelgium. > b color: Color lightGrey. > b open. Which does not display anything. I suspect the problem lies in the coordinates of my paths. Is there a README somehwere or the original file that was used to generate the world map of the examples? Cheers, Francois
