method vs. selector consistency?

methodsInCategory: aName "Answer a list of the methods of the receiver that are in category named aName" | aColl | aColl := Set withAll: (self organization listAtCategoryNamed: aName). ^ aColl asArray sort allMethodsInCategory: aName "Answer a list of all the methods of the receiver and all its superclasses that are in the category named aName" | aColl | aColl := OrderedCollection new. self withAllSuperclasses do: [:aClass | aColl addAll: (aClass organization listAtCategoryNamed: aName) ]. ^ aColl asSet asArray sort uncategorizedMethods ^ self methodsInCategory: Protocol unclassified all these methods returns selectors and not compiled methods. So I would like to rename them accordingly. What do you think? Stef

Zinc-Server-Sent-Events
by Sven Van Caekenberghe Aug. 29, 2013

Aug. 29, 2013

Hi, Server-Sent Events is a new HTML5 technology that is used to send data from a server to a client, over HTTP, on the initiative of the server. Here are some references: http://en.wikipedia.org/wiki/Server-sent_events http://dev.w3.org/html5/eventsource/ https://developer.mozilla.org/en-US/docs/Server-sent_events/Using_server-se… Zinc-Server-Sent-Events is a proof of concept implementation with a small demo of Server-Sent Events for Zinc HTTP Components in Pharo. Usage in quite simple: you specify a handler object that implements a #run: method for each outgoing feed, like this run: connection "Using Server-Sent Events is simple: keep a reference to the connection, instanciate ZnServerSentEvent objects and use #writeOn: to push them out." | event status | [ status := self statusString. event := ZnServerSentEvent type: 'status-update' data: status. event writeOn: connection. 2 seconds asDelay wait ] repeat On the client side, a standard JavaScript listener will receive the incoming events. The package can be found here http://www.smalltalkhub.com/#!/~SvenVanCaekenberghe/ZincHTTPComponents/pack… Make sure to update Zinc itself to its bleedingEdge first.

Does something for that exist
by Friedrich Dominicus Aug. 29, 2013

Aug. 29, 2013

Well laziness gets the upper half from me and I wonder if there is a software available in Smalltalk which takes an xsd fiel and generates an xml-writer from it which than adheres to the xsd descriptions. In my opinion this is too usefule to not been implemented yet ;-) Regards Friedrich

Filing in chunks
by Esteban A. Maringolo Aug. 28, 2013

Aug. 28, 2013

What is the "official" way to file in chunks in Pharo? I'm porting something from Dolphin to Pharo 2, with no purpose of having compatibility between both (it is, I want to continue with it on Pharo). I've been manually "translating" the chunk from Dolphin into Pharo format, but the problem is... I can't find a way to File In the file contents! Using the File Explorer, there is a contextual menu in the contents pane of the selected file "FileIn Selection (G)", but as soon as I select some chunks or the whole contents to file In I get a MessageNotUnderstood of #fileIn in ReadWriteStream (the selected contents). I couldn't find another menu for filing in in a Workspace (expected), SystemBrowser (Nautilus) nor anywhere else. I'm doing it with 'myChanges.st' asFileReference fileIn But I was expecting more user friendly, like a chunk browser. Any clues? Thanks! -- View this message in context: http://forum.world.st/Filing-in-chunks-tp4705341.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Recent VM for Pharo 2 on Ubuntu 8.04
by Sven Van Caekenberghe Aug. 28, 2013

Aug. 28, 2013

Hi, I asked this question before http://forum.world.st/Pharo-dev-Latest-vm-on-Ubuntu-8-04-4-LTS-tt4689467.ht… and yes I know that Ubuntu 8.04 is old, but I am really stuck. I need to deploy a Pharo #20619 image and I need a VM that works on Ubuntu 8.04 _and_ that is not 'too old' (like Eliot's most recent CogVM where I am getting lots of NB errors as well). The problem seems to be the dependency on the glibc 2.11. Has anyone successfully solved this issue ? Thx, Sven
