Squeak/Smalltalk

Hello world! We're excited to be here. On this account, we'll share news, tips, and everything else related to Squeak. If you haven't heard of Squeak, we're sure you're missing out! Squeak is the direct descendant of Smalltalk-80: an object-oriented, interactive programming system implemented entirely in itself. Lern more on https://squeak.org and follow along! Also thanks to @stewardshiplab@fosstodon.org for inviting us to #Fosstodon! #Introduction #SqueakSmalltalk #ST80 @squeaksmalltalk@a.gup.pe @st80@a.gup.pe

Did you know that Squeak offers declarative sorting? This allows you to avoid lengthy manual comparisons: animals sorted: [:a :b | a age > b age or: [ a age = b age and: [ a name <= b name]]]. Instead, you can declare and chain multiple sort functions: animals sorted: #age descending , #name ascending. Since Squeak 6.1, boolean predicates are supported as well: animals sorted: #hasTail sortedFirst , #canSwim sortedLast , #name ascending. #Programming #SoftwareEngineering
