## What it is
LibYAML is a C library implementing a YAML 1.1 parser and emitter. It exposes event-based parsing and emitting APIs, with object construction left to bindings and applications.

## Use cases
- parse YAML files in C
- emit YAML from a C program
- build language bindings for YAML
- stream-parse YAML documents as events
- embed YAML support in a native application

## When to choose
- you need a fast, low-level YAML parser in C or C++
- you are building bindings for another language (e.g. PyYAML)
- you want event-based streaming parse/emit rather than full object mapping

## When to avoid
- you want automatic mapping of YAML to native objects
- you need YAML 1.2 features
- you prefer a higher-level library in a scripting language

## Facets
- artifact type: library
- maturity: maintenance
- function: parser, serialization
- domain: parsers, developer-tools, files
- platform: c, cross-platform, windows
- tags: yaml, yaml-parser, yaml-emitter, c-library, linux, macos
