white_dune is a graphical VRML97/X3DV editor, simple NURBS/Superformula 3D modeller, animation tool, and VRML97/X3DV commandline compiler in development. VRML97 (Virtual Reality Modeling Language) is the ISO standard for displaying 3D data over the Web via browser plugins ("HTML for realtime 3D"). X3DV is the direct successor of VRML97. VRML97 and X3DV have support for animation, real-time interaction, and multimedia (images, movies, and sounds). white_dune can read, create, and display VRML97/X3DV files and let the user change the scenegraph/fields. It also has support for stereoscopic view via "quadbuffer"-capable stereo visuals, and support for 3D input devices like a joystick, spaceball, or magnetic tracker.
Bluefish is a programmer's Web development editor written using GTK, designed to save the experienced webmaster some keystrokes. It features a multiple file editor, multiple toolbars, custom menus, image and thumbnail dialogs, open from the Web, CSS dialogs, PHP, HTML, Java, C, and XML support, external program integration (tidy, weblint, make, javac), and lots of wizards.
dlh is a fast LaTeX-to-HTML translator written in C that can handle most of LaTeX. It features not invoking LaTeX for any purpose; with the exception of figure support it's completely independent of any other program. In particular, it generates all cross-references and table of contents in a single run Tables are supported and translated into HTML3 tables, and PostScript figures (\psfig command) are supported (requires GhostScript and pnmtogif to translate PS into GIF files).
OSSP sugar is a markup language and corresponding processing tool for writing technical documentation that uses a mostly invisible markup language (so-called "syntactic sugar" in compiler construction folk terminology). The idea behind it is that markup looks mostly like the textual output; i.e., the OSSP sugar source can be treated as its textual output format ("ASCII WYSIWYG"). Additionally, the OSSP sugar markup language is considered intuitive enough to be recognized and remembered easily, so writing technical documentation is mainly just a matter of performing a "brain dump". OSSP sugar provides only a few markup concepts, but those are stretched to their maximum. The syntactic principle is "keep it simple, stupid" (KISS), but it's still powerful enough to allow one to produce high-quality technical documentation.
HTMLDOC converts HTML files and Web pages into indexed HTML, PostScript, and PDF files suitable for online viewing and printing. It can be used as a standalone GUI application, in a batch document processing environment, as a Web-based report generation application, or in embedded environments to support printing of HTML content. It runs on all Unix platforms as well as Mac OS X and Windows 2000 and higher.
Mini-XML is a small XML parsing library that you can use to read XML and XML-like data files in your application without requiring large non-standard libraries. It only requires an ANSI C compatible compiler (GCC works, as do most vendors' ANSI C compilers) and a "make" program. It supports reading of UTF-8 and UTF-16 and writing of UTF-8 encoded XML strings and files, and provides a hierarchical view of the file via a linked-list tree structure of typed nodes and functions for managing, traversing, indexing, and searching the tree.
The Aida project is two-fold: it defines a simple common markup language designed to describe structured text, and it implements a compiler that translates the Aida syntax into various target formats (HTML, LaTeX, Trac, Mediawiki, Text, Markdown, and others). The system is fast, flexible, and extensible. The core command, aida, is a strict parser (written using Bison and Flex), which analyzes files written in the Aida Markup Language and invokes callbacks in order to convert them to the target format. It embeds a Tcl language interpreter and the callbacks are written in Tcl. This makes it very easy to extend the library and to define new target formats. Furthermore, the Aida files are highly parameterizable via a header and the entire system is configurable at the admin and at the user level. It is also possible to evaluate Tcl code within an Aida file and thus create dynamic contents.
LibAxl is an efficient implementation of the XML 1.0 standard specification. It doesn't have any external library dependencies, having a clean implementation based on opaque types and a consistent API to manipulate your XML documents without compromising your code. It is extremely memory efficient and thread safe with a small footprint (111k). It also includes XML Namespaces support.
