Intro Sometimes you need to extend your C++ Application dynamically during runtime with something what is not known at compile time yet. For easy things you can provide config files which may be changed prior before the application is started. The Application reads the config files on startup and use the contained settings accordingly. But […]

All about C++
I created a benchmark in C++ for testing and comparing TeaScript and its competitor ChaiScript by computing the Fibonacci number of 25 recursively. As a reference I did the same also in C++. The complete source code of the benchmark is available below. The result is pretty amazing, since with the used pre-release 0.8.0 of […]

TOP 5 most astounding C++20 Syntax
❆ Welcome 👋 to my 🎄🎅🎁 Christmas 🎄🎅🎁✨ Special✨ ❆☃! Today I present you my personal TOP 5 most astounding C++20 syntax constructs. Hope you will enjoy and maybe will see something new and/or interesting. Here it goes: No. 5: This line creates an empty lambda and directly executes it. Effectively, you can consider it […]
This post was viewed [wpstatistics stat=pagevisits time=total id=748] times. To use a classical union from C is almost always a bad idea in C++ and you should use std::variant instead. I show you why. And I also will show you in which big(!) trap I ran into myself with a union. We start with a […]
For rapid prototyping you don’t need to deal with cmake at all for can work in small groups or on different machines – the Visual Studio Property Sheets explained!
This post was viewed [wpstatistics stat=pagevisits time=total id=528] times. Following a list of my preferred and maybe (?) best Visual Studio settings for modern C++ programming based on my experience and evaluations. Each mentioned setting will be explained with some short sentences. I will cover “Release” Builds only – and I use Visual Studio 2022, […]
In this blog post you will not only learn about the repeat loop in TeaScript but also about what is a good and practical way to write UnitTests by increasing the difficulty of the tests in small steps. First let’s check how the repeat loop in TeaScript is defined:(I try to be close to this […]

C++ as a standalone script?
Since my early days as a C++ developer I wanted to use C++ code snippets as a standalone script file. Like just type the following C++20 code snippet (see my previous blog post) in a file and then execute it: But how can this be made possible?? Develop an interpreter which supports the complete set […]

Design by Introspection (C++20)
Some time ago I stumbled upon a very interesting (and for me new) technique named “Design by Introspection”, which is easily possible with the concept feature of C++20. This technique can be illustrated by the following small code snippet: First the parameter of the function value is of type auto, so it will be set […]
