Thread safe queue like collection
by Esteban A. Maringolo Nov. 24, 2013

Nov. 24, 2013

Hi, Do Pharo 2 have some sort of queue like collection, where different threads (coming mostly from a Multithread Zinc Server) can push objects into it safely, while a service on the other end can consume the queue? Regards, Esteban A. Maringolo

by Lorenz KÃ¶hl Nov. 24, 2013

Nov. 24, 2013

Nautilus has stopped jumping to packages when the focus is in the package pane and keys are pressed (the same behaviour use from eg. osx finder) Is that a regression or intended?

Deploying a polymorph app - two questions
by kmo Nov. 24, 2013

Nov. 24, 2013

I have written a small Polymorph application in Pharo 2.0. I have some questions about deploying it. My app consists of a single morph. I would like to fill the pharo window with the morph and have the morph resize when the user resizes the pharo window. I'm pretty close to what I want. I have made my morph a subclass of FullscreenMorph and it is filling the window nicely. I just need two things. One - I need to change the pharo window title to the title of my application. I have tried DisplayScreen hostWindowTitle and it seems to have no effect. Two - I need to get rid of the Pharo window status bar - the one at the bottom which shows you the various windows, browsers, and workspaces you have open. Can anyone give me some guidance? Thanks. -- View this message in context: http://forum.world.st/Deploying-a-polymorph-app-two-questions-tp4724525.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

spec and double click
by Lorenz KÃ¶hl Nov. 24, 2013

Nov. 24, 2013

I have a ListComposableModel rendered with spec that I want to do something if an element is double clicked. How do I register the event handler? I know about on:send:to but what Announcement do I use? In my testing with just a symbol #doubleClick it doesn't work (and probably isn't supposed to). thanks, Lo

Re: [Pharo-users] Writing a GUI - Where to start?

>About Glamour, isn'it used to create Browser? How can i create a typical window? What is a typical window? Spec gives too much freedom and not enough structure for 'typicalâ applications. Almost every window in your smalltalk system is a browser. Nearly all would be significantly less code when build with Glamour. Stephan

Making more memory available to VM on OS X.
by nacho Nov. 23, 2013

Nov. 23, 2013

Hi, I'm doing some fractal drawings which requires a great number of iterations and point drawing. Once the given fractal set is rendered Pharo becomes very sluggish. Is there a way to allocate more memory to the VM upon starting it? thanks Nacho ----- Nacho Smalltalker apprentice.

How to combine Pharo Desktop and Seaside?
by Torsten Bergmann Nov. 23, 2013

Nov. 23, 2013

Hi, If you want to write your collection to a static HTML page you can |aCollection| aCollection := #('Smalltalk' 'Object'). FileSystem workingDirectory / 'test.html' writeStreamDo: [:stream | stream nextPutAll: '<html><head></head><body><ol>'. aCollection do: [:each | stream nextPutAll: '<li>'; nextPutAll: each asString ]. stream nextPutAll: '</ol></body><html>']. and then serve it from an external webserver (like Apache or Nginx). But this is static html file generation. I'm sure you want something more dynamic. So you can serve the contents right from the image using one of the Smalltalk webframeworks like Seaside or Aida. Here is a short Seaside HOWTO for this: Prepare an image with Seaside ============================= - download Pharo 2.0 from www.pharo.org - start it, then select "Tools" -> "ConfigurationBrowser" from the world menu to open a list of additional loadable packages - search for "Seaside3" and click on "Install", this will install the seaside web framework into your image - When loading is finished just open a workspace ("Workspace" from world menu) and evaluate ZnZincServerAdaptor startOn: 8080 This will start a local webserver right from your Pharo image on the given port. - check with a web browser (Firefox, Chrome, IE, ...) that Seaside is running by opening http://localhost:8080 There you can browse first Seaside examples. As an alternative to the above steps you can also download a premade Seaside distribution from http://seaside.st Implement your own webapp ========================= - open the Nautlius System browser ("SystemBrowser" from the world menu) - implement an own Seaside component class WAComponent subclass: #MyHome instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'KillerApp-Web-UI' - now register this class for Seaside by evaluating the following expression in a workspace WAAdmin register: MyHome asApplicationAt: 'killerapp' This registers your component as an own custom seaside application under /killerapp. - so if you point your browser now to http://localhost:8080/killerapp you will see an empty page - but it means you application is there but has not yet some content - now implement an instance side method called #renderContentOn: on the MyHome class renderContentOn: html "Render a collection as html list" |coll| coll := #('Seaside' 'is' 'really' 'cool'). html orderedList list: coll. - refresh your browser on http://localhost:8080/killerapp you will now see the contents of the collection How to continue =============== Read books, try to implement something and if in doubt just ask on the mailinglist. There is also a seaside mailinglist http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside Learn about Pharo by getting on of these books: http://pharobyexample.org/ http://rmod.lille.inria.fr/pbe2/ learn about Seaside http://book.seaside.st/book learn about Smalltalk in general with these free books: http://stephane.ducasse.free.fr/FreeBooks.html

When I was writing the episodes, I had to read the `Spec-Examples` to figure out how to do stuff and all the examples defined `defaultSpec` as a class-side method. Maybe I'm doing it wrong.

Cleaning up Voyage Documentation
by Johan Fabry Nov. 23, 2013

Nov. 23, 2013

Hi all, I am building a small app that uses Voyage and MongoDB as the database, and so I had many questions regarding how to use it and found the documentation lacking. After conversing with Esteban, I proposed that I improve the 'Pharo for the enterprise' chapter on Voyage, based on his responses to my questions. (See https://ci.inria.fr/pharo-contribution/job/PharoForTheEnterprise/lastSucces… and https://github.com/SquareBracketAssociates/PharoForTheEnterprise-english/tr… for the sources) So a heads-up: I would like to take a 'lock' on that text for some days (to avoid conflicts and the associated unpleasantness), as I go improving and expanding it in the next few days. Also, if you have questions and/or remarks about Voyage and/or the documentation, shoot! I will do my best to address them.
