libcfp analyzes and parses the syntax of a user-supplied chemical formula in ASCII notation. It does not know anything about the semantics of real world physical element characteristics. But it requires no external library dependencies and uses namespace std:: only. Furthermore, it uses UnitTest++ during development to ensure consistent behavior of formula parsing.
The QtLua library aims to make Qt 4 applications scriptable using the Lua scripting language. It is an alternative to the QtScript module. QtLua does not generate or use generated binding code for Qt. Instead it provides useful C++ wrapper classes to make C++ and Lua objects accessible from both Lua and C++. It takes advantage of the Qt meta object system to expose QObject members to Lua scripts and comes with user manual and examples.
htmLawed is a PHP script that makes input text more secure, HTML standards-compliant, and suitable in general from the viewpoint of a Web-page administrator, for use in the body of HTML 4 or XHTML 1 or 1.1 documents. It is a customizable HTML/XHTML filter, processor, purifier, and sanitizer. It can ensure that HTML tags are balanced and properly nested tags, neutralize code that may be used for cross-site scripting (XSS) attacks, and limit the allowed HTML elements, tags, attributes, or URL protocols.
pythonOCC is a 3D CAD/PLM development library for the Python programming language. It provides 3D hybrid modeling, data exchange (support for the STEP/IGES file format), GUI management support (wxPython, PyQt, python-xlib), parametric modeling, and advanced meshing features. pythonOCC is built upon the OpenCASCADE 3D modeling kernel and the salomegeom and salomesmesh packages. Some high level packages (for parametric modeling, topology, data exchange, webservices, etc.) extend the builtin features of those libraries to enable highly dynamic and modular programming of any CAD application.
Memory Structures Library (MemSL) is a complete data structures/collection classes library with memory tracing, memory debugging, entry/exit tracing, exception handling, definable memory handlers, built-in thread support, and much more. It supports single, double, and circular linked lists, AVL balanced and threaded binary trees, dynamic hashing tables, stacks, queues and dequeues (using arrays or linked lists), sets (Pascal implementation, with union, difference, intersection, etc.), bags, tables and dictionaries, priority heaps, priority search queue, and more.
MUNGE (MUNGE Uid 'N' Gid Emporium) is an authentication service for creating and validating credentials. It is designed to be highly scalable for use in an HPC cluster environment. It allows a process to authenticate the UID and GID of another local or remote process within a group of hosts having common users and groups. These hosts form a security realm that is defined by a shared cryptographic key. Clients within this security realm can create and validate credentials without the use of root privileges, reserved ports, or platform-specific methods.
Papyrus is a 2D C++ scenegraph (canvas) library that utilizes the cairo library to perform drawing operations. Similar canvas libraries are the Gnome Canvas, Diacanvas, and the QT Canvas. Numerous canvas primitives are available, including arcs, rectangles, polylines, and line markers. An optional companion library, Papyrusmm, provides a set of Gtkmm widgets which includes viewports (a canvas display widget similar to Gtk::DrawingArea) and other UI widgets related to drawing interfaces.
