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.

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.

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.

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.

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.

This package provides the FlatBuffers serialization format for Python.

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

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.

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.

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.

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.

Msgpack is a library for C that implements binary serialization.

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

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.

The Z shell (zsh) is a Unix shell that can be used as an interactive login shell and as a powerful command interpreter for shell scripting. Zsh can be thought of as an extended Bourne shell with a large number of improvements, including some features of bash, ksh, and tcsh.

Oils is a programming language with automatic translation for Bash. It includes OSH, a Unix/POSIX shell that runs unmodified Bash scripts and YSH is a legacy-free shell, with structured data for Python and JavaScript users who avoid shell.

Tcsh is an enhanced, but completely compatible version of the Berkeley UNIX C shell (csh). It is a command language interpreter usable both as an interactive login shell and a shell script command processor. It includes a command-line editor, programmable word completion, spelling correction, a history mechanism, job control and a C-like syntax.

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.

Scsh is a Unix shell embedded in Scheme. Scsh has two main components: a process notation for running programs and setting up pipelines and redirections, and a complete syscall library for low-level access to the operating system.
