UK Smalltalk User Group Meeting - Wednesday, August 25th
by Giovanni Corriga Aug. 16, 2021

Aug. 16, 2021

The next meeting of the UK Smalltalk User Group will be on Wednesday, August 25th. Marcus Denker will talk about Variables in Pharo. We like to say that “Everything is an Object” in Smalltalk. This is true in many cases: Classes, methods, even the execution stack are reflectively available as objects. This talk shows how this idea can be extended to Variables and how Pharo implements first-class Variables for Globals, instance Variables, Class Variables, and even temporary variables. This presentation explores the Variable hierarchy, shows how variables simplify the compiler and how the reflective API provided by variables is used by the debugger. In a hands-on tutorial, we extend the language by defining new kinds of Variables. Marcus ( https://marcusdenker.de/ ) is a permanent researcher at INRIA Lille - Nord Europe ( http://www.inria.fr/lille/ ). Before, he was a postdoc at the PLEIAD lab/DCC University of Chile and the Software Composition Group, University of Bern. His research focuses on reflection and meta-programming for dynamic languages. Marcus Denker received a PhD in Computer Science from the University of Bern/Switzerland in 2008 and a Dipl.-Inform. (MSc) from the University of Karlsruhe/Germany in 2004. He co-founded Zweidenker GmbH ( https://zweidenker.de/ ) in 2009. Given the current COVID-19 restrictions, this will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/UKSTUG/events/cbklbrycclbhc/ ) to receive the meeting details.

UK Smalltalk User Group Meeting - Wednesday 28th July 2021
by Giovanni Corriga July 16, 2021

July 16, 2021

The next meeting of the UK Smalltalk User Group will be on Wednesday, July 30th. Russell Allen will talk to us about Self ( https://selflanguage.org/ ). Dating back to the late 1980s, Self is a prototype based programming language and environment in the broader Smalltalk family. Although Self has always been a niche research system, its influence can still be seen in areas as diverse as the fast VMs of Java and Javascript, in the prototype semantics of Javascript, and in the Morphic user interface used by Squeak, Pharo and Cuis. Russell Allen ( https://twitter.com/russell_allen_ ) has a background in law and computers and first came across Self in the late 1990s. Around 2008 he helped get Self running on Linux x86, set up the Self website and GitHub account, and for the last decade or so he has been helping keep Self as a project alive. In this talk, Russell will demonstrate Self as a running system, including the object semantics, language, and the multi-user Morphic development environment. he’ll talk about the current status of the project and the challenges it faces for the future. Given the current COVID-19 restrictions, this will be an online meeting from home. Please note that the meeting will start later than usual, to accomodate the speaker who will connect from Australia. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/UKSTUG/events/cbklbrycckblc/ ) to receive the meeting details.

Please up-vote Smalltalk on “Programming-idioms”
by David Mason July 10, 2021

July 10, 2021

Programming idioms is an interesting site that can lead to people programming more idiomatically in various languages. https://programming-idioms.org/cheatsheet/Ruby/Scheme/Haskell You can click on any idiom to see implementations, and all the languages are listed: https://programming-idioms.org/about#about-block-language-coverage I would very much like to have Smalltalk on the list, but the owner of the site only wants to support languages in response to explicit requests. I don’t know how many he is looking for, but if everybody on this list added a comment to the GitHub page: https://github.com/Deleplace/programming-idioms/issues/150 Note that 7 people have asked for V (which actually looks kind of interesting) but the admin hasn’t created it yet… so I’m thinking 20 or more. So please don’t assume someone else has done enough, and go and add your comment. Thanks in advance! ../Dave

UK Smalltalk User Group meeting - Wednesday June 30th
by Giovanni Corriga June 23, 2021

June 23, 2021

The next meeting of the UK Smalltalk User Group will be on Wednesday, June 30th. Hernan Wilkinson ( https://twitter.com/HernanWilkinson ) will talk about his LiveTyping project. Currently, almost all mainstream dynamically typed languages support type annotation a la Strongtalk. Python calls it "type hints", TypeScript is JavaScript+type annotations, PHP calls it "type declarations" and Ruby does it through a tool called Sorbet. All of them annotate the types in the source code and it is the programmer who must write and maintain the annotation. In all cases, it is not mandatory for the system to correctly type check for it to run. LiveTyping ( https://github.com/hernanwilkinson/LiveTyping ) is a type system proposal for Smalltalk, that seeks similar objectives but implemented in a different way. First, it is the environment itself that collects and maintains the types based on the execution of the system, not the programmer. Second, the types are not interleaved in the source code, thus maintaining the syntax and simplicity of the language. And finally, the main objective is not to carry out a static type checking (although it supports it), but to augment the programmers experience increasing the usability of current tools such as searching for senders and implementers, and performing more accurate and safe refactorings. In this talk Hernan will briefly show how LiveTyping is implemented to later concentrate on the improvements made to the tools and the benefits it brings when developing software with Smalltalk. LiveTyping is currently implemented in Cuis Smalltalk ( https://cuis-smalltalk.org/ ) and has been successfully used for the last two years in three different universities in Argentina when teaching Object Oriented Programming and Design. Given the current COVID-19 restrictions, this will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/UKSTUG/events/cbklbryccjbfc/ ) to receive the meeting details. Don’t forget to bring your laptop and drinks!
