Re: [Pharo-users] How to combine Pharo Desktop and Seaside?

by steliosgan

First of all...Thank you all for the instant response (ÎÏÏÎ±ÏÎ¹ÏÏÏ ÏÎ±ÏÏÎ¹ÏÏÎ·). I would like more precise directions as I am soooo new at this. I have the Pharo app, which returns an OrderedCollection. I created a class PrintHtml (inherents from WAComponent) with an instance variable in which I bind the ordered collection. Then, in workspace, I am trying to create an object for each of these classes, but in PrintHtml renderContentsOn: html, the instance variable looks undefined. I hope that you understand my problem. :D -- View this message in context: http://forum.world.st/How-to-combine-Pharo-Desktop-and-Seaside-tp4724166p47… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

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

How to combine Pharo Desktop and Seaside?

by Torsten Bergmann

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

Re: [Pharo-users] Spec - Tutorial Series

by Benjamin

When a Spec UI is build, the spec are looked up on class side. But in some special cases you can provide directly a SpecLayout object to a model. Why on class side? The goal was to have a static description of a widget layout Ben On 22 Nov 2013, at 11:27, Bahman Movaqar <Bahman(a)BahmanM.com> wrote: > On 11/22/2013 13:51, prova email wrote: >> Hi Bahman, >> i just finished to read the second Spec Tutorial, great tuto as >> always.

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

Hi Ben,here the .st file, there are some comments in italian, i hope it's not a problem.

My understanding is that both Spec and Polymorph are built on top of Morphic. I only looked at code example and brief tutorial for both of them, but it seemed to me that Polymorph was easier to grasp: it's quite obivous in the code where and how the widgets are built. I have trouble understanding how the job is done in Spec.
