I use Celeste in Squeak Smalltalk for my email but it does have a few limitations. Fancy quotation marks also get rendered as question marks, for example. -- Jecel

UK Smalltalk User Group Meeting - Wednesday 24 November
by Giovanni Corriga 17 Nov '21

17 Nov '21

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. Don’t forget to bring your laptop and drinks!

Block Question
by Luke McNeil 16 Nov '21

16 Nov '21

Hello, I'm trying to figure out why the code "(| x = [1] |) x value" throws this error "cannot run a block after its enclosing method has returned." What object exactly is the block's enclosing method, and when is it created? My best guess would be that when "[1]" is evaluated to be placed in slot x, it is actually evaluated in the context of a new empty method activation object. I realize that this code isn't really useful (it throws an error after all), but I am just trying to better understand what Self is doing. Thanks, Luke
