Coding by sending messages
by Matthew Chadwick June 17, 2014

June 17, 2014

hello, It's interesting that in Smalltalk, coding is still done via a text editor, not by sending messages to objects (except in the background, parsing & compiling etc). I've been playing with coding by messaging nodes in the AST with a view to coding this way via Roassal graph visualizations of object dependencies combined with some nice graphical tools. Has any work on this way of coding been done before ? What I have in mind is a keyboard-centric, fast system designed as an alternative to the text editor, with a focus on top-down style coding.

Another Pharo based solution released
by Esteban A. Maringolo June 16, 2014

June 16, 2014

Last Friday my company released a new software solution that involves Pharo in the server side. It consists of a Android based app running on tablets, used for the showcase and sales of products during expos (of retail companies), backed by a Pharo server through a REST API, and with a Seaside based admin/users web. The first expo was during the last weekend (fri-sun), and it involved the sales of a large number of orders and products (I can't disclose the numbers). The scale of the solution/user base is small, far from being "cloud scale", but it is for one of the largest consumer goods manufacturer (and the one who sold the most during the expo). Anyhow, the server handled all the request perfectly, without a single glitch. We already have some future expos scheduled. So it will continue to run along the already running Pharo based solution in the same company. Best regards! Esteban A. Maringolo

Custom layout in Spec
by webwarrior June 16, 2014

June 16, 2014

I want to make a layout based on TableLayout. Taking SpecLayout as example, it seems that I also have to create model class similar to ContainerModel and adapter for it. However, I noticed that SpecInterpreter has some hardcoded behaviour for ContainerModel in computeSpecFrom:selector: method. Is this behaviour really important, and if yes, how can I replicate it? -- View this message in context: http://forum.world.st/Custom-layout-in-Spec-tp4762142.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Roassal forms+edges

Hi, I'm trying to do a visualization that shows a group of twitter users connected to each other. It shows the images from the users but when i add the edges, the images dissapear. Here's the code: view := RTView new. e1 := RTElement on: user1. e2 := RTElement on: user2. elements := OrderedCollection newFrom: {e1. e2}. elements do: [ :e | | label shape form edge | label := RTLabel new text: e1 model name. form := Form fromFileNamed: 'aFilename'. shape := RTBitmap new form: form. e + (RTVerticalCompositeShape new shape1: shape; shape2: label) ]. line := RTArrow new color: Color red. view add: (line edgeFrom: e1 to: e2 ). view addAll: elements. view open. View without edges <http://forum.world.st/file/n4762851/withoutEdges.png> View with edges <http://forum.world.st/file/n4762851/withEdges.png> Anyone know how to fix this (show both images and edges)?? Thanks, Rosario -- View this message in context: http://forum.world.st/Roassal-forms-edges-tp4762851.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Gradualtalk
by Bob Williams June 12, 2014

June 12, 2014

I am trying to look at the annotation typing used in Gradualtalk, but I am having no success. I download the gradualtalk. zip and what I think is the correct Cog VM, but when I run Croquet I do not see any window; I do see the application running in the Task Manager. I am trying to install it on a computer running Windows Vista. The files in the Gradualtalk directory are: Croquet.exe created 4 Oct 2010 Croquet.ini Croquet.map Gradualtalk.changes created 3 12 2013 Gradualtalk.image PharoDebug.log SqueadFFIPrims.dll stderr Win32OSProcessPlugin.dll Both stderr and PharoDebug.log were created when I attempted the run. The PharoDebug.log has the following: THERE_BE_DRAGONS_HERE ==== Startup Error: MessageNotUnderstood: receiver of "do:" is nil 11 June 2014 9:36:03.002 am VM: Win32 - IX86 - 6.0 - Any help would be appreciated. Would I have more success on a Mac? bw PS: Will the annotation typing be included in a future Pharo releases?

Emails
by Bob Williams June 12, 2014

June 12, 2014

This may sound stupid, but I want to answer a specific email and all I have is the Pharo-user Digest. When I started following Pharo I had a link to a Web page that showed the emails by subject and author; however, I seem to have lost that link. All I have now is the digest and the archives. Can anyone help me?
