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

Python-cbor provides an implementation of the Concise Binary Object Representation (CBOR). CBOR is comparable to JSON, has a superset of JSON's ability, but serializes to a binary format which is smaller and faster to generate and parse. The two primary functions are cbor.loads and cbor.dumps.

This package provides a Python wrapper library to the Apache Arrow-based Feather binary columnar serialization data frame format.

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.

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.

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

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.

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.

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

libnop is a header-only library for serializing and deserializing C++ data types without external code generators or runtime support 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.

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.

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 that implements binary serialization.

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.

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

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.

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.

GNU Rush is a restricted user shell, for systems on which users are to be provided with only limited functionality or resources. Administrators set user rights via a configuration file which can be used to limit, for example, the commands that can be executed, CPU time, or virtual memory usage.

Fish (friendly interactive shell) is a shell focused on interactive use, discoverability, and friendliness. Fish has very user-friendly and powerful tab-completion, including descriptions of every completion, completion of strings with wildcards, and many completions for specific commands. It also has extensive and discoverable help. A special help command gives access to all the fish documentation in your web browser. Other features include smart terminal handling based on terminfo, an easy to search history, and syntax highlighting.
