The rencode module is a data structure serialization library, similar to bencode from the BitTorrent project. For complex, heterogeneous data structures with many small elements, r-encoding stake up significantly less space than b-encodings. This version of rencode is a complete rewrite in Cython to attempt to increase the performance over the pure Python module.

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

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.

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

Valijson is a header-only JSON Schema validation library for C++11. It provides a simple validation API that allows loading JSON Schemas, and validate documents loaded by one of several supported parser libraries.

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

This package provides the FlatBuffers serialization format for Python.

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.

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 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.

Apache Avro is a data serialization system. Avro provides:

1. Rich data structures;

2. a compact, fast, binary data format;

3. a container file, to store persistent data;

4. remote procedure call (RPC); and

5. simple integration with dynamic languages.

Code generation is not required to read or write data files nor to use or implement RPC protocols.

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

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

Cap'n Proto is a very fast data interchange format and capability-based RPC system. Think JSON, except binary. Or think Protocol Buffers, except faster.

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.

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

GNU Serveez is a server framework providing the routines necessary to easily implement IP-based servers in your application. It demonstrates aspects of network programming in a portable manner, making it convenient for both simplifying the process of adding a server to your application or for learning about how network services work. Several example servers are provided already, such as an HTTP server and an IRC server.

fish-foreign-env wraps bash script execution in a way that environment variables that are exported or modified get imported back into fish.

S is a new shell that aims to be extremely simple. It does not implement the POSIX shell standard.

There are no globs or "splatting" where a variable $FOO turns into multiple command line arguments. One token stays one token forever. This is a "no surprises" straightforward approach.

There are no redirection operators > in the shell language, they are added as extra programs. > is just another unix command, < is essentially cat(1). A andglob program is also provided along with s.

Oksh is a portable OpenBSD ksh. Not an official OpenBSD project. Unlike other ports of OpenBSD ksh, this port is entirely self-contained and aims to be maximally portable across operating systems and C compilers.

mksh is an actively developed free implementation of the Korn Shell programming language and a successor to the Public Domain Korn Shell (pdksh).
