Libfyaml is a YAML parser and emitter, supporting the latest YAML spec and passing the full YAML testsuite. It is designed to be very efficient, avoiding copies of data, and has no artificial limits like the 1024 character limit for implicit keys.

StrictYAML is a type-safe YAML parser that parses and validates a restricted subset of the YAML specification.

LibYAML is a YAML 1.1 parser and emitter written in C.

Cereal is a header-only C++11 serialization library. Cereal takes arbitrary data types and reversibly turns them into different representations, such as compact binary encodings, XML, or JSON.

LibCYAML is a C library written in ISO C11 for reading and writing structured YAML documents. The fundamental idea behind CYAML is to allow applications to construct schemas which describe both the permissible structure of the YAML documents to read/write, and the C data structure(s) in which the loaded data is arranged in memory.

Libmpack is a small binary serialization and RPC library that implements both the msgpack and msgpack-rpc specifications.

This package provides a C library for parsing and writing CSV data.

ckdl is a C library for parsing and emitting KDL. This package also provides kdlpp, a C++20 wrapper around ckdl.

qtcsv is a library for reading and writing CSV files in Qt.

Msgpack is a library for C that implements binary serialization.

FlatBuffers is a cross-platform serialization library for C++,C#, C, Go, Java, JavaScript, PHP, and Python. It was originally created for game development and other performance-critical applications.

This package provides the C implementation of the varlink interface description protocol and its associated command line tool

msgspec is a fast serialization and validation library, with builtin support for JSON, MessagePack, YAML, and TOML. It includes the following features:

• High performance encoders/decoders for common protocols.

• Support for a wide variety of Python types.

• Zero-cost schema validation using familiar Python type annotations.

• A speedy Struct type for representing structured data.

This package provides YAML parser/emitter that supports roundtrip preservation of comments, seq/map flow style, and map key order. It is a derivative of Kirill Simonov’s PyYAML 3.11. It supports YAML 1.2 and has round-trip loaders and dumpers. It supports comments. Block style and key ordering are kept, so you can diff the source.

Msgpack is a library for C/C++ that implements binary serialization. This is the legacy version that predates the split into C and C++ specific packages.

LibYAML is a YAML 1.1 parser and emitter written in C.

Libmpack is a small binary serialization and RPC library that implements both the msgpack and msgpack-rpc specifications.

YAML parser and emitter in C++ matching the YAML 1.2 spec.

This package provides two dump_to_string/dumps methods that returns YAML document as string.

Libmpack is a small binary serialization and RPC library that implements both the msgpack and msgpack-rpc specifications.

This package provides a C library for parsing scfg, a simple configuration file format with one directive per line.

Msgpack is a library for C++ that implements binary serialization.

This package provides a JSON parser written in shell, compatible with ash, Bash, Dash and Zsh. Pipe JSON to it, and it traverses the JSON objects and prints out the path to the current object (as a JSON array) and then the object, without whitespace.

JsonCpp is a C++ library that allows manipulating JSON values, including serialization and deserialization to and from strings. It can also preserve existing comment in unserialization/serialization steps, making it a convenient format to store user input files.
