A very practical introduction to Parsing Expression Grammars (PEGs), in which we’ll build a non-trivial parser using the most excellent cpp-peglib single-include C++ library. Post includes links to PEG libraries for Go, Rust and Python, and a ready to run GitHub repository of all examples.
If I’ll ever stop programming it will be because I can no longer find the energy to parse even just one more string format.

This post discusses the practical use of Parsing Expression Grammars (PEGs) and introduces cpp-peglib, a single-include C++ library that simplifies parsing. It provides examples of parsing a vector format and a string format, and demonstrates how to extract data from the parser. It also includes links to PEG libraries for Go, Python, and Rust.
