C++20 Modules with GCC11
Introduction One of the headline changes of the C++20 standard is the inclusion of modules. Modules promise to significantly change the structure of C++ codebases and possibly signal headers’ ultimate demise (but probably not in my lifetime). It also opens the door to potentially have a unified build system and…

Object-Oriented Entity-Component-System Design
About two months ago, I decided to start developing a fresh codebase for my voxel project – something that many indie developers are probably all-too familiar with, including myself. This time around, there were three major features that I wanted to implement:

Let's write a compiler, part 3: A parser
Tokenizing the source code input is a great start for our compiler. Now let's turn our attention to parsing the PL/0 grammar. Once we have finished with the parser, the front end of our compiler will be finished and we will have a PL/0 validator. This is a program that can read in PL/0 source code and inform the user…

What can be learned from studying long gone development practices?
Current ideas about the best way of building a software system are heavily influenced by the ideas that captured the attention of previous generations of developers. Can anything of practical use be learned from studying long gone techniques for building software systems?

Let's write a compiler, part 1: Introduction, selecting a language, and planning
I think we all knew this might be coming once we finished up with our assembler . While we can in theory solve any computable problem by writing the appropriate assembly for our assembler, writing assembly code can be a bit more cumbersome than a high-level language. There is a reason why we did not write our…
