UK Smalltalk User Group Meeting - Wednesday, January 26th

by Giovanni Corriga

For our January meeting, we'll be hosting GemTalk's Martin McClure who will talk about a new Smalltalk IDE - Sparkle. If you're setting out to develop a Smalltalk IDE from scratch, what design decisions do you make? You'd love to "fix" the things that have long annoyed you in existing IDEs, but new designs risk creating their own novel annoyances. The Sparkle project-in-progress is creating a new and not entirely conventional development environment for GemStone Smalltalk. Come see factors that have influenced its design, get a demo of the current state of the tools, learn about the project's next steps, and share *your* IDE annoyances. Martin heard about Smalltalk in 1975, *finally* got his hands on a running Smalltalk system ten years later, and hasn't let go since. In his 25 years on the GemStone team, Martin has worked on many aspects - some VM internals, some user interface design, but mostly all the things that go in between. In his rare spare time, he works on Mist, a Smalltalk variant with improved modularity and no virtual machine. When not dodging Covid, he does a lot of contra and country dancing. 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/282299228/ ) to receive the meeting details. Don’t forget to bring your laptop and drinks!

UK Smalltalk User Group Meeting - Wednesday, December 29th

by Giovanni Corriga

For our December meeting, Florin Mateoc will show us JsSqueak ( https://github.com/fmateoc/JsSqueak ), a JavaScript implementation of (JavaScript compiled) Squeak. Whereas SqueakJS or TruffleSqueak are implementations of the Squeak stack VM which run the Squeak bytecodes, JsSqueak compiles all the Squeak code to JavaScript (including the VM plugins), it exports the image state as one big JavaScript storeString, and then loads them, and runs the JavaScript implemented minimal VM (mostly primitives) and the JavaScript-translated Squeak methods as one combined JavaScript application. The compiled JavaScript application can be run either in a browser or in Node.js While JavaScript, especially with its newest additions, is a very powerful language, which allows us to implement most Smalltalk-specific features (e.g. processes/green threads are implemented using generator functions and recursive yield* for all invocations, DNU is implemented using proxies and proto manipulation, the Smalltalk parallel class hierarchy is implemented using JavaScript classes with static properties and their parallel prototypes hierarchy, weak classes are implemented using JavaScript WeakRef instances in their (weak) slots), one obvious challenge is implementing contexts. Since we compile Squeak classes to JavaScript classes, Squeak methods to JavaScript methods (and class-side Squeak methods to static JavaScript methods), the code runs on the native JavaScript call stack, and we do not have a mapping between the JavaScript function activations and reified contexts. Nevertheless, it turns out that, by providing specialized implementations for various aspects that are implemented using contexts/stack walking in Squeak, we can actually run almost all Squeak code as-is. Florin Mateoc ( https://fmateoc.js.org/ ) is an electronics engineer who has always loved programming and who has actually only ever worked as a software engineer. Florin has worked as a professional Smalltalk programmer in Enfin (later called ObjectStudio), VisualAge, VisualWorks, and a little bit as a hobbyist in Squeak. 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/282445345/ ) to receive the meeting details. Don’t forget to bring your laptop and drinks!

UK Smalltalk User Group Meeting - Wednesday 24 November

by Giovanni Corriga

This month, the UKSTUG will take a look at Objective-S ( http://objective.st/ ), an architecture-oriented programming language based on Smalltalk and Objective-C, by hosting his creator Marcel Weheir. As per Alan Kay, “Code seems large and complicated for what it does”. Objective-S addresses one source of this accidental complexity: using software architectural abstraction to directly expresses the much wider variety of architectural styles typical of modern software systems, compared to traditional programming languages that still follow the call/return architectural style of scientific programs from the early days of computing. Marcel Weheir ( https://twitter.com/mpweiher ) started his forays into dynamic object-oriented computing by implementing Objective-C on his Amiga 35 years ago and hasn’t stopped since. Stops on the way have been at Apple, the BBC, Microsoft and various startups, as well as contributing to Squeak. He is currently a principal software engineer at Citymapper and PhD student at HPI, where he is trying to distill some of the lessons learned from over a quarter century of industry experience into Objective-S. 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/cbklbryccpbgc/ ) to receive the meeting details.
