[Pharo Video Tutorial] How to automate building images with pharo and makefiles
by Dimitris Chloupis Nov. 4, 2016

Nov. 4, 2016

I mentioned this here and on chat several times but at last I decided to make a video tutorial about automating the process of building images so you don't have to install packages by hand https://youtu.be/2J-MUsDalXw

moving around parts of GTDebugger
by i.uhnak＠gmail.com Nov. 4, 2016

Nov. 4, 2016

Hi, Is it possible to configure the position of the GTDebugger panes to the previous version: ( http://humane-assessment.com/pierfiles/9e/kmq3rz0d783ks2m12lot6qg34ow8kd/gt… ) With the variables pane being a bit taller. I remember that some people didnât like this layout, thatâs why I am asking whether it can be configured (for people that want to use this layout). Thanks, Peter

DatePrinter
by stepharo Nov. 4, 2016

Nov. 4, 2016

Hi for a little project I need to print date in a nice way (for example french) and I wonder if someone already did that. Right now I'm extracting behavior from Date and putting it in its own class so that I can write testAPI | datePrinter | datePrinter := DatePrinter new. datePrinter inFrench; mmddyyyy. datePrinter for: (Date year: 2016 month: 1 day: 3). self assert: datePrinter print equals: '3 Janvier 2016' I will for fun see how I can add an english and spanish version.

How does Boolean ifTrue work?
by CodeDmitry Nov. 4, 2016

Nov. 4, 2016

I am looking at ifTrue: alternativeBlock "If the receiver is false (i.e., the condition is false), then the value is the false alternative, which is nil. Otherwise answer the result of evaluating the argument, alternativeBlock. Create an error notification if the receiver is nonBoolean. Execution does not actually reach here because the expression is compiled in-line." self subclassResponsibility In order to perform the block, ifTrue must somehow end up evaluating the block, but this code only sends a subclassResponsibility message to itself and implicitly returns itself. Where does the block actually get evaluated? -- View this message in context: http://forum.world.st/How-does-Boolean-ifTrue-work-tp4920873.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Keeping data with an application
by sergio ruiz Nov. 3, 2016

Nov. 3, 2016

Hey, all.. One of the things that I find SUPER necessary when developing an app is to be able to grab data from somewhere else and quickly and easily work on it from my machine. For instance, when I get a bug report that smells funny, the first thing i sometimes do is run a script that grabs the production data, and populates my local database with that data. i am fleshing out a project that i would really like to use Teapot (REST) for. i could then write several front ends in whatever framework/language. I was thinking about using Voyager, but the problem is, the data is VERY relational (see below, if interested).. objects are linked to each other fairly tightly. I donât know if this would be the way to handle the data, as there would be lots of duplication using mongodb as a datastore. Of course, my first thought is Gemstones, but I donât know how to grab the production data and pull it into my local development system. Does anyone have any thoughts on this?Â For those curious about the data design, i am setting up a REST server for an collaborative internet radio applicationâ¦ - there would be a global pool of stations (just streaming urls with metadata, really) - each user can select from or contribute to the global pool - users can add tags to stations (or search through the global stations based on tags) - users can attach comments to stations not complex or intimidating at all, and super easy to model in smalltalk, but not sure about how to store data so that I can quickly grab production data and troubleshoot if if necessary.

There was this book (and some others of the same ink) that was provided with my first computer: http://www.colorcomputerarchive.com/coco/Documents/Manuals/Hardware/Getting… I actually had the french version. http://www.colorcomputerarchive.com/coco/Documents/Manuals/Hardware/Color%2… This thing is still sitting near my desk today (I guess it keeps me connected to my curious young self or something like that). I keep on thinking that it would be great to have a Pharo-based version of it.

small examples to show the tools
by Christian Haider Nov. 3, 2016

Nov. 3, 2016

Hi all, in two weeks, I am going to give a little talk about Smalltalk: http://metameute.de/nook2016/ . It is 45 min with students who probably never heard of Smalltalk. I want to concentrate on the liveliness of the environment with the tools: Workspace, Inspector, Browser and Debugger. For this, I need a simple but nice example. I will use VisualWorks 8.2 and Mirko, a new Smalltalk lover, will use Pharo 5. We want to have the computers connected, maybe also a Pi, to show the platform independence of the image concept. The first idea was a chat client. A client and a server in one image. Then in two images on one machine, on two machines (also the Pi), maybe in two dialects (VW, Pharo). Possible to transfer code (blocks) across images (that should blow their minds :)). This is cool, but I am not sure if this is not too much and distracting with other technologies. Another is to read a csv file or web service and parse it into objects. With the right kind of cool data it is fun to mold these objects for the tools. This not so sexy, but easy to do from scratch. Unfortunately, the different computers would not play a role. As you see, I am a bit lost and wanted to ask you guys for ideas. Happy hacking, Christian P.S. Here in LÃ¼beck, a town in northern Germany, the attitude towards Smalltalk is generally positive, interested and curious. Maybe it is time for a Smalltalk renaissance?

using zinc wss instead of ws on windows or linux machine
by itayy Nov. 3, 2016

Nov. 3, 2016

hi all, i was building a an app with pharo and zinc, after i finished the first part i wanted to upgrade the security and so to move from ws to wss. the server is on a windows based machine, and when i change from ws to wss nothing happens. im using pharo 5 as the server. do i need to install something else to navigate the secure traffic to the server? and if yes what? and what do i need to config? if i run it on Linux will it solve the problem or do i need to config something also? if i use nginx gateway for wss then send it to pharo in ws will it work? every help will be great :D -- View this message in context: http://forum.world.st/using-zinc-wss-instead-of-ws-on-windows-or-linux-mach… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

UDP Socket primitive failure
by Dimitris Chloupis Nov. 2, 2016

Nov. 2, 2016

Hey guys I try to use Pharo to use Supercollider via OSC. OSC library is maintained by Stef in STHub. So SC informs that it receives the messages sent, but in Pharo I am getting annoying Primitive errors that I paste bellow. Anyone knows if this a bug or something missing here ? Also SC sometimes it informs me that the message was received in a different port than it was sent. Here the code I am using (OSCMessage for:{'/mixer.volume'. 1 . 0.2})sendTo: '127.0.0.1' port: 57120. Any help greatly appreciated. Supercollider is an application which is basically a server written in C++ that does music composition and audio synthesis live , its extremely powerful and the top professional audio tool for audio synthesis and music live coding. http://supercollider.github.io Socket(Object)>>primitiveFailed: Socket>>errorSending:startingAt:count:toHost:port: Socket>>primSocket:sendUDPData:toHost:port:startIndex:count: Socket>>sendUDPData:toHost:port: OSCMessage(OSCPacket)>>sendTo:port: UndefinedObject>>DoIt OpalCompiler>>evaluate RubSmalltalkEditor>>evaluate:andDo: RubSmalltalkEditor>>highlightEvaluateAndDo: [ textMorph textArea editor highlightEvaluateAndDo: ann action. textMorph shoutStyler style: textMorph text ] in [ textMorph textArea handleEdit: [ textMorph textArea editor highlightEvaluateAndDo: ann action. textMorph shoutStyler style: textMorph text ] ] in GLMMorphicPharoScriptRenderer(GLMMorphicPharoCodeRenderer)>>actOnHighlightAndEvaluate: in Block: [ textMorph textArea editor highlightEvaluateAndDo...etc...
