PLEASE NOTE that we are in the process of moving to GitHub: https://github.com/libexpat/libexpat This is James Clark's Expat XML parser library in C. It is a stream oriented parser that requires setting handlers to deal with the structure that the parser discovers in the document.

libmng -THE reference library for reading, displaying, writing and examining Multiple-Image Network Graphics. MNG is the animation extension to the popular PNG image-format.

jq is like sed for JSON data - you can use it to slice, filter, map and transform structured data with the same ease that sed, awk, grep and friends let you play with text. jq is written in portable C, and it has zero runtime dependencies. You can download a single binary, scp it to a far away machine of the same type, and expect it to work. jq can mangle the data format that you have into the one that you want with very little effort, and the program to do so is often shorter and simpler than you'd expect. Data in jq is represented as streams of JSON values - every jq expression runs for each value in its input stream, and can produce any number of values to its output stream. jq filters run on a stream of JSON data. The input to jq is parsed as a sequence of whitespace-separated JSON values which are passed through the provided filter one at a time. The output(s) of the filter are written to standard out, again as a sequence of whitespace-separated JSON data.

matio is an C library for reading and writing MATLAB MAT files.

BioSig is a software library for processing of biomedical signals (EEG, ECG, etc.) with Matlab, Octave, C/C++ and Python. About 50 different data formats are supported.

FLAC is a free lossless compressed audio format which supports streaming and archival. The FLAC project maintains the format and provides a reference encoder/decoder and input plugins for several popular audio players.

gputils is a collection of tools for Microchip PIC microcontrollers. Its goal is to be fully compatible with Microchip's tools, MPASM, MPLINK, and MPLIB.

OpenCTM is a file format, a software library and a tool set for compression of 3D triangle meshes. The geometry is compressed to a fraction of comparable file formats (3DS, STL, COLLADA...), and the format is accessible through a simple, portable API

The Systems Biology Markup Language (SBML) is an XML-based description language for representing computational models in systems biology. Visit the project web site to learn more.

libcsv is a small, simple and fast CSV library written in pure ANSI C89 that can read and write CSV data. It provides a straight-forward interface using callback functions to handle parsed fields and rows and can parse improperly formatted CSV files.

Libnodave is a library that provides the necessary functions to connect to and exchange data with Siemens S7 300/400 PLCs (200 family and S5 family now also supported). Can now also be used under Win32.

A simple editor for dbf files. The editor is built with GTK+, making it available on a number of platforms, including Linux and Windows.

HT is a file editor/viewer/analyzer for executables. The goal is to combine the low-level functionality of a debugger and the usability of IDEs. We plan to implement all (hex-)editing features and support of the most important file formats.

Apache Guacamole is a clientless remote desktop gateway. It supports standard protocols like VNC, RDP, and SSH. We call it clientless because no plugins or client software are required. Thanks to HTML5, once Guacamole is installed on a server, all you need to access your desktops is a web browser.

TAPClean is a Commodore tape preservation / restoration tool. It will check, repair, and remaster Commodore 64 and VIC 20 TAP or DC2N DMP files (tape images).

Software libraries and tools designed for implementation and testing of the Common Image Generator Interface (CIGI), an interface for communication between an image generator (IG) and host device in simulations.

Cross-platform command-line tool for creation of PDF documents from scans/photos of pages in JPEG (.jpg) format and the lightest weight ANSI C library to put multiple JPEG files into one PDF file. You can add handwritten comments to PDF scans (over original images) with xournal: http://xournal.sourceforge.net/ It supports graphics tablets and saves comments to PDFs as vector data.

The gawkextlib project provides several extension libraries for gawk (GNU AWK), as well as libgawkextlib containing some APIs that are useful for building gawk extension libraries. These libraries enable gawk to process XML data, interact with a PostgreSQL database, use the GD graphics library, and perform unlimited precision MPFR calculations. These extensions work with GNU AWK version 4.1.1 or later. We have created a framework for packaging gawk extensions, and we welcome further contributions. Recent additions include haru, redis, and select for I/O multiplexing.

Eddystone is an open Bluetooth Low Energy beacon format from Google that defines a set of frame types for broadcasting structured data to nearby devices. It was designed to be simple for hardware makers to implement and flexible for applications to consume in mobile platforms and the web. The standard includes unique identifier frames for asset tracking, telemetry frames for device health and battery, and a URL frame that points scanners directly to web content. A rotating, ephemeral identifier variant supports privacy-preserving deployments where beacons regularly change their broadcast identity. Reference code and documentation show how to craft frames, configure advertising intervals, and interpret signals on the receiver side. Eddystone helped catalyze “physical web” style experiences by making proximity signals easy to deploy and consume across ecosystems.

Portable and very simple C API functions to write a soap client/server in c.
