UKSTUG meeting (*with corrected links*) - Christian Haider: How values make systems simpler - 25 Sep 2024 @ 7pm BST
by UK Smalltalk Sept. 23, 2024

Sept. 23, 2024

Distinguishing between stateful Objects and Values has long been recognized as fruitful. Values are universal context-free abstractions that prevent side effects and allow for a functional programming style. Though programming languages provide simple Values like Integer and String, more complex Values are usually not supported. We show how to model complex structures as Values in Smalltalk, which allows for a simple and versatile implementation. The resulting Smalltalk systems are simple, clear and easily testable. Christian Haider [1] is the author of the PDFtalk library [2] used in smallCharts [3] and other projects. Underlying is a simple implementation of Values [4] which he uses extensively. Christian will show how Values make systems simpler and easier. Examples for some uses and the limits of the approach will be discussed. Since Values use only standard Smalltalk features, it can be used in most other Smalltalks. All of this code is available with MIT licence. This will be an online meeting from home.

Jetbrains

Dear friends I forward you an email we got from jetbrains. Please check the survey or reply to them directly. S. Hello, fellow Smalltalkers! At JetBrains, we are committed to pushing the boundaries of software development. As part of this ongoing effort, our research team is designing a next-generation software development stack inspired by the core principles of Smalltalk. The new programming language will incorporate better support for functional programming and gradual typing while remaining faithful to the original Smalltalk spirit. The IDE will combine structural navigation in the tradition of Smalltalk with projectional editing, powerful autocompletion and support for AI-assisted development. To ensure this vision aligns with the needs of the developer community, we are actively seeking insights from experienced Smalltalk practitioners. Learning about your experience and future aspirations is crucial to our success. We invite you to contribute by taking our brief survey <https://surveys.jetbrains.com/s3/smalltalk-survey> or contacting us directly <http://pavel.mikhailovskii@jetbrains.com/> to engage in a more in-depth discussion.
