## What it is
libgraphqlparser is a C++11 parser for the GraphQL query language, exposing both C++ and pure C APIs. It uses flex and bison to generate the parser and includes a code-generation framework for AST classes and visitors, making it a foundation for building language bindings.

## Use cases
- parse GraphQL queries in a C++ application
- build a GraphQL parser binding for another programming language
- convert GraphQL query text into a JSON AST representation
- analyze or validate GraphQL syntax in a C or C++ codebase
- implement a GraphQL server or toolchain from scratch

## When to choose
- you need a fast native GraphQL parser with C or C++ APIs
- you are writing bindings for a language that lacks its own GraphQL parser
- you want programmatic access to a GraphQL AST with visitor support

## When to avoid
- you only need GraphQL parsing in JavaScript, Python, or another high-level language with native parsers
- you want a full GraphQL execution engine rather than just parsing
- you need Windows support, which is not listed as supported

## Facets
- artifact type: library
- maturity: maintenance
- function: parser, sdk
- domain: parsers, apis, developer-tools
- platform: cpp, c, python
- tags: graphql, ast, flex-bison, language-bindings, macos, linux
