14.1 Parsing Command Line Arguments Building command line tools (CLI) is a common task in Rust practical projects. Rust provides various ways to parse command line arguments, with the most common approach being the use of third-party libraries like <span>clap</span> or <span>structopt</span>. These libraries help us easily define and parse command line arguments, handle user … Read more
Cyclang is a simple statically typed programming language that supports basic language constructs such as functions, control flow, and arithmetic operations. The language’s feature design is very concise, and the complete language specification can be referenced in the official documentation. The focus of this project is on the process of building a compiler from scratch … Read more
Handling files and paths is a frequent task in any programming language. In C++, we used to rely on platform-specific APIs (such as CreateFile on Windows or open in POSIX) to accomplish this. This approach was not only cumbersome but also required consideration of cross-platform compatibility issues. The good news is that with the introduction … Read more
