C-ares is a C library that performs DNS requests and name resolution asynchronously. It is intended for applications which need to perform DNS queries without blocking, or need to perform multiple DNS queries in parallel. The primary examples of such applications are servers which communicate with multiple clients and programs with graphical user interfaces.

The goal is to provide a concrete library focused on verification examples, as opposed to mathematics. The library has a good number of theorems for booleans, natural numbers, and lists. It also has trees, tries, vectors, and rudimentary IO. A number of good ideas come from Agda's standard library.

Agda is a dependently typed functional programming language: it has inductive families, which are similar to Haskell's GADTs, but they can be indexed by values and not just types. It also has parameterised modules, mixfix operators, Unicode characters, and an interactive Emacs interface (the type checker can assist in the development of your code). Agda is also a proof assistant: it is an interactive system for writing and checking proofs. Agda is based on intuitionistic type theory, a foundational system for constructive mathematics developed by the Swedish logician Per Martin-Löf. It has many similarities with other proof assistants based on dependent types, such as Coq, Epigram and NuPRL.

The standard library aims to contain all the tools needed to write both programs and proofs easily. While we always try and write efficient code, we prioritize ease of proof over type-checking and normalization performance. If computational performance is important to you, then perhaps try agda-prelude instead.

A new Categories library for Agda

This Emacs mode enables interactive development with Agda. It also aids the input of Unicode characters.

A standard library for Cubical Agda, comparable to agda-stdlib but using cubical methods.

A formalised, cross-linked reference resource for mathematics done in Homotopy Type Theory. Unlike the HoTT book, the 1lab is not a “linear” resource: Concepts are presented as a directed graph, with links indicating dependencies.

libdmtx is software for reading and writing Data Matrix 2D barcodes of the modern ECC200 variety. libdmtx is a shared library, allowing C/C++ programs to use its capabilities without restrictions or overhead.

Zbarlight is a simple wrapper for the zbar library. It can read all zbar supported codes.

Zint is a suite of programs to allow easy encoding of data in any of the wide range of public domain barcode standards and to allow integration of this capability into your own programs.

ZXing-CPP is a barcode scanning library.

ZBar can read barcodes from various sources, such as video streams, image files, and raw intensity sensors. It supports EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 93, Code 39, Codabar, Interleaved 2 of 5, QR Code and SQ Code. Included with the library are basic applications for decoding captured bar code images and using a video device (e.g. webcam) as a bar code scanner. For application developers, language bindings are included for C, C++ and Python as well as GUI widgets for GTK and Qt.

Libqrencode is a C library for encoding data in a QR Code symbol, a kind of 2D symbology that can be scanned by handy terminals such as a mobile phone with CCD. The capacity of QR Code is up to 7000 digits or 4000 characters, and is highly robust.

ZXing-CPP is a barcode scanning library.

qrcodegen-cpp is a QR code generator library in C++. The project also offers Java, Javascript, Python, C, and Rust implementations.

libdmtx is a software library that enables programs to read and write Data Matrix barcodes of the modern ECC200 variety. This package, dmtx-utils, provides command line utilities that allow scripts and command line users to use libdmtx functionality.

This package includes the following programs:

1. dmtxquery: Extract information from dmtxread output.

2. dmtxread: Scan Data Matrix barcodes.

3. dmtxwrite: Create Data Matrix barcodes.

GNU Barcode is a flexible tool to produce printed barcodes from text strings. It supports a variety of encoding standards and sizing measurements. Barcodes can be output in PostScript or Encapsulated PostScript formats.

Read one-dimensional barcodes and QR codes using the zbar library.

Features:

• Pure python

• Works with PIL / Pillow images, OpenCV / numpy ndarrays, and raw bytes

• Decodes locations of barcodes

• No dependencies, other than the zbar library itself

JLargeArrays is a Java library of one-dimensional arrays that can store up to 263 elements.

The gf2x library provides arithmetic of polynomials over finite fields of characteristic 2. It implements the multiplication, squaring and greatest common divisor operations.

FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data---i.e. the discrete cosine/ sine transforms or DCT/DST).
