C++ command line parameters parser (CLPP) is a command line parameter parser with callback functions and, if necessary, type/semantic checking of values of input parameters. It uses only Boost C++ libraries and ISO C++. It is header-only (no need to build it) and very simple to use.
Configurator is a configuration file parser. It allows you to use arbitrary nesting of sections. The user can define an option's default value, necessity, and semantic check. It supports single-line and multi-line comments (in C++ style). It provides common checks of options and sections, like duplication, incorrection, etc. It uses only Boost C++ libraries and ISO C++. It is header-only (does not require building) and very easy to use.
Falcon is a simple, fast, and powerful programming language, easy to learn and to feel comfortable with. It is also a scripting engine, easily embeddable in any complex, multi-threaded and mission-critical application. Falcon provides its users with four integrated programming paradigms: procedural, object oriented, functional, and message oriented. And you don't have to master all of them; you just need to pick the paths that are ingredients you prefer, and let the code to follow your inspiration.
The Hummus PDF Writer library allows you to generate PDF files. It was developed with a principal “one-off” method of generating PDF files. Adhering to this idea, it is both fast and retains a low memory signature regardless of how large the file grows. The library has a set of high level features for adding content to a PDF, including creation of pages; drawing primitives and any of the simple PDF operators for drawing content; embedding of PDF, JPEG, and TIFF images; Unicode text support with Type1, TrueType, and OpenType fonts; and defining reusable objects using XObject Forms. You can also use the library as a PDF parser. The library is very extensible. It is easy to implement more PDF features by using the lower level set of methods, which provide access to the PDF building blocks themselves. Adding a feature requires you to be familiar with the PDF formatting of that feature, but will not require you to write the basic PDF building blocks, as the library handles this.
Knotter is a highly configurable interlace designer. Interlace patterns are a kind of design historically used as a decorations in many places and by different cultures (some examples are Celtic knotworks and Islamic interlaces). Knotter aims to allow its user to design such patterns in an intuitive way and to provide easy ways to integrate the result into external general-purpose graphic software. For this purpose, designs created within Knotter can be saved in a custom human-readable format and exported as Scalable Vector Graphics and in a wide number of raster image formats.
MW is a low footprint embedded UI framework core intended for use on very limited systems. It embeds the JPEG, Freetype, and Cairo libraries, so it only depends on X. It should be fairly portable, as the only thing you need is to create a window on every platform and manage the events.
