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

Voyage
by horrido Feb. 8, 2019

Feb. 8, 2019

I'm trying to load Voyage for MongoDB and I'm having great difficulty. The docs seem to be out of date. What are the current instructions for doing this? The docs also refer to "Configurations Browser" in World Menu/Tools, but there is no longer any such thing. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Porting Github packages to Pharo 7
by HernÃ¡n Morales Durand Feb. 2, 2019

Feb. 2, 2019

I would like your advice on this: What's the effortless way to migrate Github repository from Pharo 6 to Pharo 7? I thought in the following solutions: 1) In a Pharo 6 image modify my BaselineOf, add & push a new package MyPackage-Pharo6, then load it into a Pharo 7 image, create MyPackage-Pharo7 and port as needed. The same Metacello installation script is preserved for all versions. 2) Tag repository as x.x in a Pharo 6 image, load my package & do port in a Pharo 7 image and push to master. Previous Pharo 6 version could be loaded referring to a tag (or branch maybe?) in the Metacello installation script. Any recommendations? Alternative paths? Cheers, HernÃ¡n

Hi, I downloaded separately stable P7.0 32 bits image and linux VM. When I fire up, I got this start up error related to Git (which I do not use), see log. It looks like reproducible problem. On the CLI, there is a funny error message "file too short": hilaire@PCHome:~/Travaux/Developpement/DrGeoII/trunk/build/tmp/vm$ ./pharo ./Pharo.image ioLoadModule(./lib/pharo/5.0-201901051900/libgit2.so): Â ./lib/pharo/5.0-201901051900/libgit2.so: fichier trop court ioLoadModule(/home/hilaire/Travaux/Developpement/DrGeoII/trunk/build/tmp/vm/./lib/pharo/5.0-201901051900/libgit2.so): Â /home/hilaire/Travaux/Developpement/DrGeoII/trunk/build/tmp/vm/./lib/pharo/5.0-201901051900/libgit2.so: fichier trop court tryLoading(/home/hilaire/Travaux/Developpement/DrGeoII/trunk/build/tmp/vm/lib/pharo/5.0-201901051900/libgit2.so/.libs/,libgit2.so): stat(/home/hilaire/Travaux/Developpement/DrGeoII/trunk/build/tmp/vm/lib/pharo/5.0-201901051900/libgit2.so/.libs/) N'est pas un dossier External module not found ExternalLibraryFunction(Object)>>error: ExternalLibraryFunction(Object)>>externalCallFailed ExternalLibraryFunction(ExternalFunction)>>invokeWithArguments: LGitLibrary>>libgit2_init FFICalloutAPI>>function:module: -- Dr. Geo http://drgeo.eu

Seaside or Iliad for business applications?
by Siemen Baader Feb. 1, 2019

Feb. 1, 2019

Hi, Iâm a very happy Iliad user but Iâm wondering if it would make sense to switch to Seaside for commercial development since it has a larger user base. I have only used Seaside briefly to try it out and found I was more happy with Iliad back then, but now Iâd like to hear your input. Especially from those of you who use it for business applications with paying customers. My questions are: - does Seaside support partial updates of the DOM, like Iliad, or do I need to refresh the whole website for every interaction? - Iliad has REST-like URLS that look clean and can be shared, Seaside seems not to. Is this possible with Seaside? - directly writing javascript. I suppose there is a WAComponent that can emit raw JS? - what is the status of Websocket / Comet in Seaside? Is there anything else I should consider? thanks, Siemen

How to intercept every instance variable write on all objects
by Petr Fischer Jan. 31, 2019

Jan. 31, 2019

Hello, is possible to intercept (before writeÃº all instance variable writes on every existing objects? I found a discussion here: http://forum.world.st/Is-it-possible-to-follow-an-object-through-a-computat… Known solutions: 1) jugglery with object read only state + ModificationForbidden - not ideal, it's probably slow via exceptions and every nested on:do: stop change detection 2) it's possible to do it via slots - but it does not work on any existing object (only on my specially prepared objects with slots) 3) Metalinks - it's based on intercepting method calls, right? But I need to intercept direct instance variable write, so probably not possible Is there any way? Thanks! pf
