history
Project history and usage
cpp-peglib is Yuji Hirose's single-header C++ PEG parser library. It packages Parsing Expression Grammar support as a C++17 header-only dependency, with peglint as the command-line tool exposed by the Homebrew formula.
Project history
The public GitHub repository was created in February 2015. Upstream describes the project as a C++17 header-only PEG library that can be used by including peglib.h directly in a project.
The README documents support for packrat parsing, left-recursive grammars, semantic actions, grammar loading, and an online PEG Playground. That positioning makes the project attractive to users who want parser-combinator-like ergonomics without a generated parser build step.
Adoption history
The supplied package facts list Homebrew and MacPorts. Header-only C++ libraries are often consumed directly from source, so package-manager adoption mainly helps users install the header and peglint consistently.
How it is used
cpp-peglib is used to embed PEG grammars into C++ applications, build small DSL parsers, and lint grammar definitions. Upstream examples show calculator grammars, semantic actions, error logging, token boundaries, predicates, and packrat parsing.
Why package nerds care
For package maintainers, cpp-peglib is a tidy example of a header-only C++ library with a useful companion executable. Its C++17 requirement and pthread note for some Linux distributions are the main packaging details.
