direct image code exchange
by Sebastian Heidbrink Aug. 10, 2015

Aug. 10, 2015

Hi again, I find my self more and more often showing others Pharo and very often it might be great to just push code changes from one image directly to another. Is there a in-image monticello server available that would mimic a repository server? I already thought about webannouncements as a solution to broadcast/push code within the network. Or a shared remote playground that keeps a websocket connection between images and would provide an easy way to copy&paste snippets... @Stephan: How did you solve your latency issues with your remote introductions? Couldn't one just extend gui announcements by web announcements to remote control other images? Sebastian

Debugging announcements
by Ben Coman Aug. 10, 2015

Aug. 10, 2015

How are Announcements currently debugged? I vaguely remember I was once able to use AnnouncementSpy [1], but that seems not in Pharo5 anymore. Anyway, I'd rather avoid having to hunt within existing for a particular announcer to observe. What I'd really like is something like... RubTextAcceptRequest spy ...to be able to observe anySuchAnnouncement in anyAnnouncer. [1] http://pharo.gemtalksystems.com/book/LanguageAndLibraries/announcements/ann… cheers -ben

Accepting Email Drops on Pharo Window
by Sean P. DeNigris Aug. 10, 2015

Aug. 10, 2015

Does anyone have experience with accepting drops of file types which are not supported by default? On StackOverflow [1], it was shown how to do this in Cocoa: ``` [window registerForDraggedTypes:[NSArray arrayWithObjects:(NSString*)kPasteboardTypeFileURLPromise,nil]]; ``` but do I really need to modify the VM? It seems like, since Smalltalk is so malleable, and more like an OS than an app, we should accept all types and let the user decide whether to do something with them, no?

[ANN] New ISO 3166-1 Wrapper
by HernÃ¡n Morales Durand Aug. 10, 2015

Aug. 10, 2015

Dear all, I developed a Pharo ISO 3166-1 wrapper to access objects into a ISO3166-1 model. See the following post for details on installation and usage: http://80738163270632.blogspot.com.ar/2015/08/new-iso-3166-1-implementation… I also wrote some documentation about it: https://dl.dropboxusercontent.com/u/103833630/ISO3166.pdf Hope you find it useful.

troubles with JNIPort on Pharo 5 / Java 8
by Tudor Girba Aug. 10, 2015

Aug. 10, 2015

Hi, I am having trouble running JNIPort with Pharo 5 and Java 8 on Mac OS X 10.10.4. The code loads fine: Gofer new smalltalkhubUser: 'JNIPort' project: 'JNIPort'; configuration; loadVersion: '3.0-alpha'. However, I do not know where to point "JNIPortJNIInterface libraryFile:" to. In the original instructions for Java 1.6, the code looked like: JNIPortJNIInterface libraryFile: '/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Libraries/libclient.dylib' With JDK 1.8 (and even 1.7), the file organization seems to be different and the libclient.dylib does not exist. 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"

Image cannot grow beyond 500Mb
by Tapple Gao Aug. 9, 2015

Aug. 9, 2015

I am trying to use Moose to do run graph algorithms on data with about 300,000 nodes. This data is map data downloaded from OpenStreetMap, and I am trying to analyze it with the Moose-Analysis-Graphs package. However, it seems completely unable to handle this, partially due to unoptimized algorithms, but mostly due to memory limits of the VM or image itself. I am using the vm and image of the moose one-click image for mac: http://www.moosetechnology.org/#install <http://www.moosetechnology.org/#install> . I believe this is a pharo vm and image, I donât know if pharo and squeak are still different these days, or if it matters. Been out of squeak for a few years This platform is seemingly unable to use more than about 500Mb of memory. I watch it in macâs activity monitor. Once it reaches about 450Mb as measured by activity monitor, it is spending nearly all itâs time in the garbage collector, (as measured by activity monitorâs Sample Process tool). The most Iâve seen it eventually reach is 556Mb, after about an hour, then it does a hard VM crash (Pharo has quit unexpectedly). Is there a way to remedy this? I tried running the image in 4 alternative VMâs: - The latest pharo mac vm from http://files.pharo.org/vm/pharo/mac/ <http://files.pharo.org/vm/pharo/mac/> . Same issue as above. likely the same vm - Cocoa Cog vm from http://squeakvm.org/mac/ <http://squeakvm.org/mac/> : crashed at startup. could not load image - Cocoa Stack vm from http://squeakvm.org/mac/ <http://squeakvm.org/mac/> : crashed at startup; could not load image - Carbon Stack vm from http://squeakvm.org/mac/ <http://squeakvm.org/mac/> : refused to start Is it possible to allocate more than 500Mb of memory to squeak?

MongoDB: console commands? query embedded indexed fields?
by Sabine Manaa Aug. 8, 2015

Aug. 8, 2015

Hi, I have 2 questions concerning use of mongoDB classes: 1) how can I send mongo console commands directly from smalltalk 2) how to query on an embedded collection with an index Model: I have trips and each trip has an embedded collection of N receipts like this: { "tripName" : "trip 1", {"receipts" : [ {"receiptDescription" : "receipt 1" } {"receiptDescription" : "receipt 2" } {"receiptDescription" : "receipt 3" } ], } Index: For quick search, I created an index on the embeded[1] receipts with this command at the mongoDB console in a terminal (NOT in smalltalk) (mongo console starts with mongo in the MongoDB/bin dir): db.Trips.createIndex({"receipts.receiptDescription":1}) with a command like this in the mongoDB console db.Trips.find({"receipts.receiptDescription":"receipt 1"}) I get the resulting receipt. Before, I have to set the database with "use {databasename}" in thr mongodb console My questions: 1) how can I send mongo console commands directly from smalltalk, e.g. use database, set index etc. Is this possible? I did not succeed with the mongo command: method, it always returns "no such cmd". 2) how can I search for a receipt which is indexed as described from smalltalk? I did not succeed with the description [2] I am not sure if it is covered by it.

Proper way to retrieve Monticello repositories
by Peter UhnÃ¡k Aug. 8, 2015

Aug. 8, 2015

Hi, what is the proper way to retrieve Monticello repositories? I've always simply queried the system for instances... e.g. MCSmalltalkhubRepository allInstances detect: But is there some manager or something? (Akin to RPackageOrganizer default) Also it's interesting that both Pharo50 and Pharo50Inbox are MCHttpRepository instances and not MCSmalltalkhubRepository. Thanks, Peter
