XIDEK is an extensible interpreter development kit. It supports an interpreter and simple compiler development with a small but complete collection of reusable, extensible parsing and support modules. These modules implement standard expression and statement syntax, including control statements, symbol tables, abstract syntax trees, and simple bytecode interpreters. They can be used as a starting point for rapid development of language processors for script languages, "little languages", or domain-specific languages. Numerous documented examples show how to combine and extend the base modules into custom interpreters.
hpdf.js is a scrip to create PDFs in your browser (it is a port of libharu). Existing projects with the same goal lack a lot of features (e.g. custom fonts). hpdf.js supports custom fonts (Type1 and TTF), PNG, JPEG, and RAW images, password protection, text and link annotations, outlines, drawing function (lines, cycles etc.), encoding support, and more.
The Open Game Libraries is a collection of separately usable C++ libraries for creating games. It provides OpenGL window management, zip file management, OpenAL audio management, a developer console window, input management, bitmapped fonts with Unicode and kerning support, image loading and saving, model loading and importing, and generic classes and objects for game development such as math and text processing.
glbmp is a lightweight and portable partial glaux replacement, providing auxDIBImageLoad and related device-independent bitmap image loading functionality. At the basic level, it's a flexible bitmap loader and decoder that can be used anywhere the color data of a bitmap is required. It supports uncompressed monochrome, 16 color, 256 color, and 24-bit bitmap files of any size, and allows for flexible output formats.
objSQL is a PHP-based database access layer for multiple database servers. Primarily designed for small-to-medium projects, it uses an "Object Based" approach for handling general database queries. Built-in support for transactions and prepared statements allow for a common interface to all supported database types. Recordset paging is simplified by incorporating the paging method along with many helper methods for general queries. objSQL is easily extended to create your own unique classes and methods.
XSLT syntax highlighting is an implementation of syntax highlighting as an extension module for Java based XSLT processors (such as Xalan or Saxon). For example, if you have an article about programming written in DocBook, code examples can be automatically syntax highlighted during the XSLT processing phase.
