>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

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

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.

How to combine Pharo Desktop and Seaside?

Hello, I am a newbie at smalltalk and I do not feel so comfortable with the following question : I have created an application with Pharo 2.0 and I would like to know if I could present dynamically some results to an html page, using seaside. (Actually, I have a class that creates an OrderedCollection and I want to create an html table to fill it with the data from the collection).Is it feasible? Thank you -- View this message in context: http://forum.world.st/How-to-combine-Pharo-Desktop-and-Seaside-tp4724166.ht… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

How to combine Pharo Desktop and Seaside?
by Torsten Bergmann Nov. 22, 2013

You can initialize your instance variable in an initialize method WAComponent subclass: #PrintHtml instanceVariableNames: 'tasks' classVariableNames: '' poolDictionaries: '' category: 'KillerApp-Web-UI' Then a method to initialize on the instance side PrintHtml>>initialize: initialize "initialize the receiver" super initialize. tasks := #('read' 'before' 'you' 'try') If you send #new to a class this #initialize method is automatically called. If you do not want it use #basicNew. So if you enter PrintHtml new in a workspace and select "Inspect it" to open an inspector on the new object this method gets called and therfore you will see that the instance variable should have the collection as contents. Side note: Do not forget the "super initialize" in this method - otherwise superclass initialization for seaside components is not done. Then use a normal rendering method to display the ivar in the browser renderContentOn: html html orderedList list: tasks If I understand you correctly you want to know how you acces the Seaside generated code for a WAComponent subclass also in a workspace. This is easy: |component| component := PrintHtml new. "your seaside component" WARenderCanvas builder render: [ :html | html render: component ] which should return the generated HTML: '<ol><li>read</li><li>before</li><li>you</li><li>try</li></ol>' now. That is one way. The preferred way for Seasiders is to directly look at the generated HTML code in the webbrowser. Just go to your app: http://localhost:8080/killerapp Down at the bottom you will find the seaside development toolbar (only visible when developing) and then click on "Halo". Now Seaside renders a rectangle around each component and you can click on "Source" to Switch to the source of a component. Also try the other buttons there. For sure you should read one of the introduction stuff on Seaside, I would recommend the online Seaside book: http://book.seaside.st/book Bye T.

We know that the documentation right now is far from optimal. Ben and I will work on that in January. Iâd recommend to try to build your application with Glamour first. Only if that doesnât provide a good fit, take a look at spec. Spec is much more powerful, but too low level for most applications. Stephan

The dependency on AST-Core is removed. I guess it makes sense to have a ci build for this. Can I get access to pharo-contributions to create a build? Stephan
