sMArTH is an equation editor built on open Web standards. The editor itself uses a SVG interface and the application logic is implemented in ECMAScript using the DOM. Both MathML and LaTeX are supported as exporting formats in addition to the SVG format. The most important mathematical content from both LaTeX and MathML is already provided, and this should cover the need of the majority of users. The graphical user interface allows even the most complex equations to be built with simple "Point and Click" techniques instead of writing convoluted typesetting code.
VTeX/Lnx is a TeX program that generates PDF or PostScript output immediately from the TeX source file. In contrast to pdfTeX, VTeX supports inclusion of PostScript images (EPS), as well as inline PostScript programming, even when generating PDF output. VTeX includes a complete LaTeX system, Bibtex, and Makeindex. Packages such as PStricks, PSfrag, and draftcopy can be used with VTeX.
PyC2LaTeX converts a given C, Java, or Think/Fractal adl or idl file into a LaTeX file that can be used for pretty-printing the code. It features line numbering, indentation, support for international characters, and syntax highlighting. The text in the output is otherwise unmodified. One of the main goals of this script is to provide LaTeX code that can be directly included in other LaTeX files to write software documentation.
IDX-DocBook2LaTeX is a stylesheet which translates DocBook documents into LaTeX. It is written in Perl, using the XML::XPathScript package from AxKit. It features the ability to handle tables, indices, figures, footnotes, and more. The XSLT-like templating philosophy built into XPathScript makes it easy to extend.
