Using Spotter
by Alexandre Bergel June 8, 2015

June 8, 2015

Hi! If in spotter: 1- enter: Roassal2 #p 2- select: Roassal2 and press cmd -> 3- enter: Zoom Then I see all the classes that belongs to Roassal that have the word Zoom in them. The question I have is: how can I look for all the classes having Zoom in their name and begins with the prefix âRTâ? I have tried âRT*Zoom*â. I remember Juraj showed me a way to do this, but I forgotâ¦ Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

VoyageMongo/Magritte problem
by mtk June 8, 2015

June 8, 2015

Hi, maybe I found an issue in VoyageMongo/Magritte, here is what I've done: loaded a fresh Pharo 4.0 image loaded VoyageMongo via Configuration Browser (Install Stable Version) opened up a Playground and did (via the green 'play' button): |repository| repository := VOMongoRepository host:'hostOn.mongolab.com' port: 43158 database:'databasename' username: 'username' password: 'password'. repository enableSingleton. repository inspect. This leads to an error which seems to be connected to 'gtInspectorMagritteIn:' (see attached screenshot) which was updated in the package Magritte-GT on 03.06.2015. (no instance 'repository' is going to be created). Please excuse my bad analysis on this, because I have only very limited skills. <http://forum.world.st/file/n4830859/VoyageMongo.png> -- View this message in context: http://forum.world.st/VoyageMongo-Magritte-problem-tp4830859.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Issue with UDP Sockets
by Manfred KrÃ¶hnert June 7, 2015

June 7, 2015

Hello everyone, I am currently trying to get a list of UPnP device via SSDP (Simple Service Discovery Protocol). A minimalistic working NodeJS example looks like this: var dgram = require('dgram'); var message = new Buffer( "M-SEARCH * HTTP/1.1\r\n" + "HOST:239.255.255.250:1900\r\n" + "MAN:\"ssdp:discover\"\r\n" + "ST:ssdp:all\r\n" + "MX:1\r\n" + "\r\n" ); var client = dgram.createSocket("udp4"); client.on("message", function (msg, rinfo) { console.log("server got: " + msg + " from " + rinfo.address + ":" + rinfo.port); }); client.send(message, 0, message.length, 1900, "239.255.255.250"); client.close(); I tried to recreate the same functionality in Pharo with the following piece of code: | message udpSocket host | message := 'M-SEARCH * HTTP/1.1\r\n' , 'HOST:239.255.255.250:1900\r\n' , 'MAN:"ssdp:discover"\r\n' , 'ST:ssdp:all\r\n' , 'MX:1\r\n' , '\r\n'. udpSocket := Socket newUDP. host := (NetNameResolver addressFromString: '239.255.255.250'). udpSocket sendData: message toHost: host port: 1900. "udpSocket waitForData." Transcript show: 'Received: ' , udpSocket receiveData. udpSocket closeAndDestroy. Unfortunately, this script hangs both in Pharo3 and Pharo4 (OS X 10.10, Pharo 30856 and 40611). When I interrupt with Cmd+. the debugger shows the method Socket>>waitForDataIfClosed: and the hang is apparently in the line self readSemaphore wait Could anyone give me some advice if I should to do this differently or what the issue with the Pharo script is? Thanks in advance, Manfred

loading Coral from SmalltalkHub
by Francisco Garau June 7, 2015

June 7, 2015

Hello, I've tried loading Coral by following the below instructions in its website <http://rmod.lille.inria.fr/coral/getting-started.html> but they failed when trying to load Readline. Gofer new url: 'http://ss3.gemstone.com/ss/coral'; package: 'ConfigurationOfCoral'; load. ConfigurationOfCoral loadDevelopment. It seems the project was moved to Smalltalk Hub ( http://smalltalkhub.com/#!/~PharoExtras/Coral/) What expressions should I evaluate in a Pharo5 image to get the latest Coral project loaded. Thanks, Francisco

Protocol selection erratic behaviour
by Sergio Fedi June 6, 2015

June 6, 2015

When creating a method in the debugger, when the select protocol pop up window appears, sometimes it finds the protocol we want (getter) and sometimes it doesn't and we have to type it all and add it as if it was new. Is this something normal and my expectations are off? Or is this a bug?

collectionDo: vs. collection do:
by Peter UhnÃ¡k June 5, 2015

June 5, 2015

Hi, is there some best practice about collectionDo: versus collection do: ? I see many times the first used (e.g. String>>linesDo:); I see a benefit if there is no accessor to the collection, but more times than not there actually is. >From my perspective it further pollutes the protocol and as a user of such method I will never be sure what to actually use without looking at the implementation to see if there is any actual difference. So is there some consensus on this? Thanks, Peter

Proposed enhancements to get.pharo.org
by Jason Rogers June 4, 2015

June 4, 2015

I have a simple suggestion for the ZeroConf Bash scripts. The suggestion is to automatically discern the image that the scripts use. E.g. For the pharo script: https://gist.github.com/jacaetevha/7c4206d2cfadd54a492c#file-pharo For the pharo-ui script: https://gist.github.com/jacaetevha/7c4206d2cfadd54a492c#file-pharo-ui I tried to bring this up in the IRC channel, but things seem pretty quiet there. I'm not sure where to post this, so I'm just posting it here. -- Jason Rogers
