The correct statement is what I said before: 1) Trial versions are 45 days limit 2) Trial versions are the full version of the product, that is, there is no kind of limit or missing functionality (like creating executables).

What is the idiomatic way to store data in pharo?
by Steve Quezadas Jan. 28, 2020

Jan. 28, 2020

I am writing a simple "quote-of-the-day" object for pharo that stores both quotes and pictures. What is the "idiomatic" way of storing data in pharo? Do I connect to some sort mysql database or is there a better "smalltalk" way to do it? Forgive the naive question. - Steve

Re: [Pharo-users] Pharo image processing library
by Pablo Navarro Jan. 28, 2020

Jan. 28, 2020

Hi everyone! Thanks for the comments, I don't create a repository yet because, in this first version, I just wanted to try if it was possible, so only create a Form subclass and add three methods. Form subclass: #ImageForm instanceVariableNames: 'mode' classVariableNames: '' package: âSmallImage' ââ> + aImage "add two image and return a new ImageForm" |aImageResult| aImageResult := self deepCopy. 0 to: self width do:[:x| 0 to: self height do:[:y| |aPoint aColorA aColorB| aPoint := (Point x: x y: y). aColorA := aImageResult colorAt: aPoint. aColorB := aImage colorAt: aPoint. aImageResult colorAt: aPoint put: aColorA + aColorB. ]]. ^ aImageResult â-> show: anTitle "Show a image in a window, scale the image to 500" |im| im := (ImageMorph withForm: (self scaledIntoFormOfSize:500) ). im withSnapshotBorder. im borderWidth: 5. im color: (Color gray). im openInWindowLabeled: (anTitle,' | mode: ', self mode asLowercase, '| ', self shape). -â> The first problem I found was the class Form return 'Form new' and not 'self class new' so I had to create two class method (in ImageForm): newFrom: aForm mode: aMode "create an ImageForm from to a Form object." | aImage| âaImage := self new. âaImage copyFrom: aForm. âaImage mode: aMode. â^ aImage. â> open:Â aFileName âOpen a image.â | aImage aForm| Â aForm := ImageReadWriter formFromFileNamed: aFileName. âaImage := self newFrom: aForm mode: âARGBâ. â^ aImage. â> I think that the methods (+ and show) should be directly in the class Form but I didn't want to change the original. If you think it's okay, I can continue working and this week upload to github with their respective tests. P.S. sorry for my limited English. Best Regards Pablo.

Is Pharo is a good frontend system for a game console?
by ponyatov Jan. 28, 2020

Jan. 28, 2020

Good day I'm playing with custom little Linux for retrogaming console based on Raspberry Pi 4. Is Pharo is a good frontend system (GUI) for a game console? There is no mouse or keyboard by default, only joystick. So running Smalltalk interface on system bootup has some questions on usability. Also, it should be able to run external native binary programs that can use OpenGL and SDL/SDL2 so I'm not sure is the Pharo graphics system will be run on direct framebuffer without X11, and is it stable to be used with such libraries. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Fwd: Morph menu entries
by Richard Kenneth Eng Jan. 27, 2020

Jan. 27, 2020

Could someone please explain what the "World contents" menu obtained by right-clicking on the background is all about? (I normally left-click to obtain the "World" menu.) Why are there all those morphs listed? And is this potentially a problem? Thanks. ---------- Forwarded message --------- From: Bob Nemec Date: Sat, 25 Jan 2020 at 10:16 Subject: Morph menu entries Hey Richard, Iâm still learning Pharo, so I donât know what this means, but when I right-click on the desktop I see a long list of StringMorph entries. Later Iâll try starting with a new image. Is there a more recent JRMPC file-out youâd like me to use? *Bob Nemec* *HTS Toronto *| ontario.htseng.com 115 Norfinch Drive | Toronto, ON M3N 1W8 C: 905.442.4539 | T: 416.661.4060 Ext 2255 | F: 416.661.0100 *Delivering Real SuccessÂ®*

New Smalltalk Blog
by Richard Kenneth Eng Jan. 26, 2020

Jan. 26, 2020

I've created a new Smalltalk blog <https://smalltalk.tech.blog/>. I've left Medium because of their pressure to put everyone behind a paywall. I've opened up the blog for third-party submissions. Anyone can email me an article submission and if I deem it appropriate, I will edit and publish it. Here's an example from Leandro Caniglia, President of FAST: Extending the Smalltalk Syntax <https://smalltalk.tech.blog/2020/01/20/extending-the-smalltalk-syntax/>. Articles should serve to showcase why Smalltalk is such a great language. If possible, an accompanying eye-catching feature image would be nice. (If you look at the other posts, you'll see images of a Maserati and a Tesla!) I would prefer the article submissions to be in LibreOffice format. It would make it easier for me to edit. Thanks, Richard

Workspace with reliable save feature
by HilaireFernandes Jan. 26, 2020

Jan. 26, 2020

Hi, Do we have an external workspace with a deterministic save feature. I looked at the catalog but found none, Both Workspace and Playground fall short. Workspace save file with 0 byte of content! Playground, with my experience with student, is absolutely not reliable to save script, its auto-save feature always results in lost of code. Particularly when combined with its rename and its inexplicit save behaviour. It is not practical to edit script and save code. I will start a second round of coding with students (12-14 yrs old) and I need them to save their code. The only viable option I see is to ask them to copy and to past their code in an external editor ! It will be a mess for sure and waste of time and energy. Any alternative idea or option I failed to see ? Hilaire ----- http://drgeo.eu -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
