Re: [Pharo-users] Why won't my Pharo download run?

Just a little more information. Out of curiosity, I downloaded Pharo 3.0 and tried it, with the same result - message from Windows says 'Pharo.exe has encountered a problem and needs to close'. To complete the set, I downloaded Pharo 1.4 and tried it. This time it failed saying 'CogVM.exe has encoun....'. I presume all versions now use the Cog VM, and it looks as though this machine just won't run it. Is there still a 'traditional' VM I can use instead of Cog? It might not be practical, but it would at least prove that it is a VM problem. Is there any information about Cog giving problems with AMD processors? _____ From: Pharo-users [mailto:pharo-users-bounces@lists.pharo.org] On Behalf Of PBK Research Sent: 07 November 2013 15:07 To: 'Any question about pharo is welcome' Subject: Re: [Pharo-users] Why won't my Pharo download run? OK. I opened a command line prompt, cd to Pharo 2.0 directory (created in today's download), enter 'pharo.exe pharo2.0.image'. Same result - immediate failure. I had previously changed the association of the image file to the newly downloaded pharo.exe. So I think I must be using the VM in today's download. _____ From: Pharo-users [mailto:pharo-users-bounces@lists.pharo.org] On Behalf Of Igor Stasenko Sent: 07 November 2013 14:48 To: Any question about pharo is welcome Subject: Re: [Pharo-users] Why won't my Pharo download run?

A simple an basic calculator built with Spec
by nacho Nov. 7, 2013

Hi, I wanted to share with those you could be interested a project I did to learn a little about Spec in Pharo 3. It's a simple and very basic calculator. There code is all commented and I even include a little tutorial on how I build the UI. There are a number of issues however that I have to figure out being the most important a way to get the text displayed to be right-aligned. Also error handling and other...my point was just to focus on Spec. If you are interested you can get it here: MCHttpRepository location: 'http://ss3.gemstone.com/ss/Specalc' user: '' password: '' and then Calculator new openWithSpec. best regards Nacho ----- Nacho Smalltalker apprentice.

Dear Mac OS X users, could you load this slice from Pharo30Inbox in a Pharo 3.0 image, save your image, and launch it again. SLICE-Issue-12092-Pharo-cant-find-sources-files-when-embedded-in-an-app-application-DamienCassou.2 Do you still have the error "Cannot locate the sources file named /Applications/PharoV20.sources" ?

Why won't my Pharo download run?

Spec - TextModel whenTextIsAccepted
by Bahman Movaqar Nov. 7, 2013

Nov. 7, 2013

Hi all, I'm writing a simple graphical version of the legendary "Hello, world". I have a window with a text field, a button and a label. What I'm trying to do is to make the button (which is initially disabled) enabled upon user entering text. However, it seems that the user first must "Accept" the text for the action to be fired. Here's some snippets of code: <code> initializePresenter textName whenTextChanged: [ buttonGreet enable ]. buttonGreet action: [ labelGreeting text: 'Hello, ', textName text, '!'. buttonGreet disable ]. initializeWidgets self instantiateModels: #( textName TextModel labelGreeting LabelModel buttonGreet ButtonModel ). labelGreeting text: ''. buttonGreet label: 'Greet Me!'; disable. </code> What am I doing wrong? TIA, PS: I have tried `whenTextChanged` to no avail --it shows the same behaviour. -- Bahman Movaqar (http://BahmanM.com) ERP Evaluation, Implementation & Deployment Consultant PGP Key ID: 0x6AB5BD68 (keyserver2.pgp.com)

Writing a GUI - Where to start?

Glad that it was usefull. Meanwhile HPDF is outdated (still on FFI, a port to NativeBoost would now be state of the art) and we also have Artefact for PDF generation as a "Pharo only" solution. One question: did you "hard code" the PDF layouts for the documents in the "lawsuitTracker" or what did you use to (quickly) define the report layouts? I would like to see some kind of general reporting engine in the future. Either a pharo based one or by using templates from existing engines (for instance JasperReports has a nice visual ui designer and layout templates are stored in XML files) With a future UIBuilder for PharoUI's, Seaside for Web-UI's and a (Pharo based) ReportingEngine Pharo could be an attractive solution to build business software...

Re: [Pharo-users] I would rather pay for Smalltalkhub than use Github for free.

I see some very strong arguments against depending on github: - it is centralized infrastructure, essentially unsuitable for use with a distributed version control system; - it doesnât support working at the right granularity; - the smalltalk community is too small to have any influence on the directions github is taking. It is a commercial organization that can decide to do something we donât like at any time. It is free, so we are the product. Just take a look at sourceforge; - we can do much better than github (but donât have enough time). We should be using a P2P, bittorrent like system for version control. Stephan
