[ANN] Scheduler moved to GitHub pharo-contributions/Scheduler

by Torsten Bergmann

Hi; "Scheduler" ws migrated from SmalltalkHub to GitHub - it is an easy-to-use task scheduler that can run arbitrary blocks. See attached image for a quick example. A few things have been cleaned as well: - separate tests into own package - class comments - categorize classes and methods - fix lint problems - follow SUnit best practices (super tearDown, super setUp) - removed unnecessary "super new initialize" call on class side - add a Travis CI job - ... https://github.com/pharo-contributions/Scheduler It is usable and working in recent Pharo versions Enjoy! Bye T.

Re: [Pharo-users] UK Smalltalk User Group Meeting - Wednesday, May 27th

by Tim Mackinnon

Before the lockdown, when you could meet in the pub, we were blown away when Alan nervously approached us and asked if we were the UKST group as he was keen to meet some Smalltalkers as heâd been using this music system written in Smalltalk ... it was an amazing story that Iâm sure heâll get into again for everyone.

Thanks, Stephane, I'll switch to P9. > png is better and there is a library to manage icons > I do not have the name but you can load icons. > But look around. For icons I found the necessary code in ThemeIcons>>loadIconsFromUrl. Here's a simplistic approach to load icons from PNGs in a local ZIP archive, if somebody needs it: | themeIcons newIcons | newIcons := IdentityDictionary new. themeIcons := ThemeIcons new. ((FileSystem zip: 'C:\icons\a.zip' asFileReference) open workingDirectory allChildrenMatching: '*.png') do: [ :each | newIcons at: each base asSymbol put: (themeIcons readPNGFrom: each )]. newIcons.

Re: [Pharo-users] Spec2 Pharo8/9; icons

by StÃ©phane Ducasse

Hello Tomaz > Dear all, > > What would be the best Pharo version to start building a Spec2 GUI for an app - Pharo 9 which is under development but with novelties in Spec2, or Pharo 8? I would go for P9. It may be a bit shaky from time to time but for example you can milestoned your image and if the next one is shaky you wait. We are always developing in bleeding edge so eating our own dog food (and p9 has been nice so far). Just now we got Spec20 0.6 and it contains many improvements. I hope to be able to start to code some mini tutorial (learning myself and writing what Iâm learning). > What's the best (easiest ...) way to import new icons into Smalltalk ui icons?

I'm using Pharo on Windows and I uninstalled it completely and reinstalled, so I will use your suggestions. > > Another question, if I may, is what order of books should I use? I purchased "Pharo 5 by Example" (because it was newer than "Pharo by Example," "Learning Object-Oriented Programming, Design, and TDD with Pharo," "Deep Into Pharo" (which I know would be after PBE), and "Enterprise Pharo" (which would probably be after Deep into Pharo). You mentioned that you know how to program so in a couple of days you should get up to speed. Our data is that 3rd students takes two weeks and I know people that did the mooc in speed run in two days. I would follow the mooc. You will get much faster and there is an image 32 that is in sync with the mooc version. The mooc is of excellent quality because we put 10 years of teaching experience in it. We are working on a mooc version with Pharo by Example 80. We are about to release 70 new videos of scenarios around Pharo 80. Just verifying the titles of such slides and videos take time. Then you can read in diagonal Pharo by Example (I hope to get some time to update chapter 3 this week-end). After I would read in diagonal some chapters there and there and ask questions. I think that in a couple of days you should get up to start developing a small app. You do not need to know everything. In PBE8 there are two new chapters on Pharo and git. To get started. Deep into Pharo is not really needed. This is more extra knowledge and Iâm currently updating some chapters for P8. I extracted the Zinc HTTP chapters, but you can develop seaside without caring about http. To get started you need to know how to define a class and a method. S.

> > > Hello, > > I feel your pain. > Updated, consistent and centralized documentation is not strong in Pharo. I cannot let you say that sorry :) We have a mooc with more than 100 videos We have books that are maintained. This is not by accident or fun that I spent time updating Pharo by Example and creating a collection of booklets. We regularly update them. We have lectures. We have a single wiki with documentation. > Things are changing fast and docs don't catch up, also there is an effort to move projects to github, so usually updated stuff are there. I never use Catalog anymore because often things goes wrong. Books are only good to explain major concepts that are less likely to change over time, in order to getting started I would recommend: > > 1- Seaside github project: https://github.com/SeasideSt/Seaside <https://github.com/SeasideSt/Seaside>.
