Of all the responses here, I like this one the best because it's right on the money. In my long career, I've been dropped into many software projects where I had to quickly ramp up with a new programming language. The employer didn't hire me for my language expertise; they hired me for my programming skill and ability to deliver good quality software on time. The programming tool used was a mere technicality, and hardly an obstacle. There is not a software developer alive who can coast through their entire career without ever needing to pick up another programming language. This is simply not an issue except for the most myopic of employers.

Bloc texts font size
by Steven Costiou Oct. 20, 2017

Oct. 20, 2017

Hi, i am trying to set the font size of a BlTextElement, and i do not have much success. I use the following code to add the text element, where 'model' is a string. First, if the string is '0.0' then the font size is correct (see screenshot). But, if for example the value is '21.0' then the font size is wrong (see the other screenshot). I don't understand, i've tried variants but it seems to me that this code was the right way to do it. Sometimes, a '9' would be displayed at the correct font size, sometimes not. Any ideas ? text := BlTextElement new text: ((BrRopedText string: model) attributes: {(BrTextForegroundAttribute paint: (Color green alpha: 0.8)). (BrFontSizeAttribute size: 60). (BrFontWeightAttribute weight: 50). (BrFontGenericFamilyAttribute monospace). "(BrFontFamilyAttribute named: 'Source Sans Pro')"}); yourself. text constraintsDo: [ :c | c frame horizontal alignCenter. c frame vertical alignCenter ]. "text is added to a parent BlElement" self addChild: text Second, i don't have the impression that changing the font family does have any effect (but maybe its my local setup i don't know...).

ANN: Smalltalk Express Blog
by Peter Fisk Oct. 20, 2017

Oct. 20, 2017

Hi everyone, I have started a new blog to discuss the "Smalltalk Express" framework. https://smalltalkexpress.quora.com/ Smalltalk Express is web development framework using a Smalltalk interpreter written in the "Go" language. The first blog post provides some details and a video. A few months ago, I built an experimental framework called "Rails Express" which had an interactive interpreter based on Ruby. The feedback that I have received has been fantastic. "Smalltalk Express" uses all the same UI techniques and is designed to be capable of production deployment. I am intending to offer "Smalltalk Express" initially as a service based on Google's App Engine, but I would be happy to hear any ideas of how to market the product. The product website will be "smalltalk.express" (smalltalk - dot - express). Thoughts and feedback are welcome. Cheers, -- Peter -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Anoying bug fond in Artefact running in Windows 10
by casimiro.barreto＠gmail.com Oct. 19, 2017

Oct. 19, 2017

When you insert a jpeg from a file, for some reason the file descriptor (stream) is kept open (at least in the Windows end of things). Then, if a second page is to be generated, the following error is shown: 'MessageNotUnderstood: receiver of "reset" is nil PDFJpegElement>>stream: JPEGReadWriter aJPEGReadWriter JPEGReadWriter(ImageReadWriter)>>on: nil Sample code: aPage := PDFPage new. imageStream := FileStream fileNamed: 'lsi-tec.jpg'. aPage add: ((PDFJpegElement fromStream: imageStream) from: 15 mm @ 20 mm; dimension: 40 mm @ 40 mm). imageStream close. Generated report is in annex The only way to recover is to close pharo, start it again. Then the file descriptor (stream) is released and it is possible to go on. Has anyone faced this problem? How to solve it? Best regards, Casimiro Barreto

Pharo and instance variables ...
by James Ladd Oct. 19, 2017

Oct. 19, 2017

Hello Pharo Users, I'm wondering about instance variables for support in Redline Smalltalk and want to get my understanding straight. Are instance variables only accessible (without using #instVarNamed:) inside the method with the same name as the instance variable? eg: myInstVar ^ myInstVar. Or can you reference an instance variable from a method that doesn't have the same name ? anotherMethod ^ myInstVar. Can someone give me or point me to an example of accessing an instance variable in Pharo Smalltalk? - James. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

iceberg - changing non-code files in the same commit as code
by Peter UhnÃ¡k Oct. 18, 2017

Oct. 18, 2017

Hi, this is maybe a bit advanced use case from Iceberg perspective, but quite basic from git perspective. Use case: In the same commit where code has changed I want to update text file CHANGELOG.md. Right now I need to modify the file after the commit and then amend it (so it is in the same commit), but it would be nice to do everything from within Pharo. Thanks, Peter

How do you mock http?
by Herby VojÄÃk Oct. 17, 2017

Oct. 17, 2017

Hello! I felt the need to mock http api (like nock in node, that is, mock http request-response itself on low-level part, leaving aside the question of what wrapper / library one uses to get to that http; in node it mocks basic http layer, here I tackled ZnClient), but struggled for a time how to grasp it. Finally I used something like this (with help of Mocketry, `1 to: 10` to mean "enough to actually be used even if there are more unrelated uses", it could as well be `1 to: 100`): ZnClient stub new willReturnValueFrom: ((1 to: 10) collect: [ :i | ZnMockClient whenRequest: [ :request | { request uri scheme. request uri authority. request uri pathPrintString. request uri query associations asSet } = { #https. 'onesignal.com'. '/api/v1/players/{1}' format: { UUID fromString36: 'Q7' }. { 'app_id' -> appId } asSet } and: [ #(GET HEAD) includes: request method ] ] thenResponse: [ :request | ZnResponse ok: (ZnEntity json: '{}') ] ]). with the help of this class (garbled utf not my fault, iceberg metacello integration does it): 'From Pharo6.0 of 13 May 2016 [Latest update: #60512] on 17 October 2017 at 12:05:38.908634 pm'!

I am a mock ZnClient. I am created with ZnMockClient whenRequest: whenBlock thenResponse: thenBlock.

Question 1: Is there a better way? Question 2: If not, would ZnMockClient be good addition to Zinc itself, to ease testing for others? Herby

DesktopManaker from Ctrl-D to Ctrl-M help needed!!
by Ricardo Pacheco Oct. 17, 2017

Oct. 17, 2017

Hello. I'm using the Desktop Manager add on in my Pharo 6, but I really dislike the fact that its key shortcuts start with Ctrl-D because it hides the Do-It command. So I looked into the code and changed in the class method DesktopManager >> desktopMenuCommandOn:, to use Ctrl-M instead of Ctrl-D. After saving the new key shortcuts are working now. Nevertheless the old Ctrl-D based are still functional. The question is, how do I disable them? In other words, I do I make the system reset its key short-cuts? Is there a tool where I can see all the active key short-cuts of the system and manage them? Thanks a lot. PD to the DesktopManager team: Your tool is really cool, thanks a lot; nevertheless is not nice to hide the Do-It command -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

GDPR and the pharo website
by Bruce O'Neel Oct. 15, 2017

Oct. 15, 2017

Hi, We're having some discussions on the Squeak side about GDPR and squeak.org. Â Are there any thoughts about changes to pharo.org for GDPR? Â We have similar web presences so one imagines similar issues. Â If GDPR is not ringing any bells you can startÂ [http://www.eugdpr.org](http://www.eugdpr.org), and the most interesting pages are probablyÂ [http://www.eugdpr.org/key-changes.html](http://www.eugdpr.org/key-changes.h… andÂ [http://www.eugdpr.org/gdpr-faqs.html](http://www.eugdpr.org/gdpr-faqs.html). Thanks. bruce
