Mobile dev is good for your health!
Some development days go exactly as hoped. This is one of them. Starting from almost nothing — on a framework I barely knew — I built a fully-featured MOGWAI REPL in a single session, running natively on Windows, Linux and macOS. With the help of my buddy Claude, of course. The context: why Avalonia? I’ve … Read more
MOGWAI 8.7 is now available on NuGet. This release does not introduce any major architectural change — instead, it consolidates and extends what already exists, with four new primitives covering distinct needs and two significant bug fixes. guid7 — truly sortable identifiers MOGWAI already offered guid to generate UUID v4 identifiers. Version 8.7 adds guid7, … Read more
The Formula Calculator app is a concrete example of what you can build with GIZMO in just a few lines: the user types a mathematical formula with a variable X, defines a range and a step, and gets a table of computed values on the fly. The full source code is available in the GIZMO … Read more
When I first published the MOGWAI Playground earlier this year, the idea was straightforward: provide an online environment to test MOGWAI code without installing anything. A terminal in the browser, a few clickable examples, and the full engine running in WebAssembly. Functional, but limited to single-line input. Today, the playground takes a significant step forward … Read more
There is a category of applications we tend to forget in a world dominated by graphical interfaces: terminal-based applications. Robust, lightweight, fast to launch, usable over SSH — they have qualities that GUIs simply don’t. But building them often requires mastering complex frameworks in less accessible languages. That was the starting point for GIZMO. What … Read more
The starting point MOGWAI is an open-source stack-based RPN scripting engine for .NET that I have been building and using in production for several years. If you are not familiar with RPN (Reverse Polish Notation), think of the execution model used by HP calculators: operands are pushed onto a stack, and operations consume them. MOGWAI … Read more
April 30, 2026. It’s around midnight. I’m sitting at my desk with a simple idea: what if MOGWAI had its own VS Code extension? Twenty-four hours later, it was published on the Marketplace. Here’s the story of how it happened — and the central role Claude played in this adventure. The Starting Point MOGWAI has … Read more
MOGWAI just hit version 8.6, and this one comes with two features that have been on the roadmap for a long time: a full object-oriented programming system, and a built-in assertion primitive. Let’s take a tour. Object-Oriented Programming in a Stack-Based Language If you’ve been following MOGWAI for a while, you know the language is … Read more
MOGWAI CLI is an open source .NET project for using MOGWAI on PC. It includes a code editor to create programs directly within the application.
Martin, a developer, needs to read a binary file from an undocumented sensor. This article explains how MOGWAI makes it easy to manipulate binary data, including construction, extraction, and endianness handling.
