About:
cpp-peglib is a header-only C++ library that provides a PEG (Parsing Expression Grammar) parser generator. It allows developers to define grammars directly in C++ code, enabling the creation of parsers without external build steps. Its main value proposition is delivering powerful parsing capabilities with minimal dependencies and straightforward integration.

Key Features:

Header-only library for easy integration
Grammar definition directly in C++
Supports semantic actions and error recovery
Zero dependencies beyond the C++ standard library

Use Cases:

Implementing domain-specific languages (DSLs)
Parsing configuration files or data formats
Building language interpreters or compilers
Protocol message parsing

Alternatives:

Boost.Spirit – More comprehensive but heavier dependency and steeper learning curve.
ANTLR – Requires separate code generation step and runtime library.
