## 项目历史与用法

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.

### 项目历史

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.

### 采用历史

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.

### 使用方式

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.

### 为什么软件包爱好者会关心

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.
