PHPTAL is a fast, safe, XML-based template engine for XHTML and HTML5. It implements Zope's Template Attribute Language, which has clean, concise syntax that is compatible with XML tools (no custom ugly tags), and template source files can even be previewed in Web browsers or opened in WYSIWYG editors. Templates are compiled to PHP and cached, giving great performance and taking advantage of PHP accelerators. PHPTAL by default ensures well-formed output and escapes XML-unsafe characters everywhere, which means that your pages can be completely safe against HTML-injection (XSS) without great effort. It features fine-grained caching of output, pre- and post- filters, internationalization via gettext or custom backend, creation of custom template attributes and expressions, and templates loaded from non-standard sources (e.g. databases). It supports UTF-8 well, is easy to integrate and redistribute with PHP frameworks and applications, and has an object-oriented design and a comprehensive unit test suite.
MkDoc is a C and C++ code documentation tool. It parse complex code and still produces clear documentation for developers and library users. Unlike most code generation tools, it does not simply write generated code documentation with pieces of user text inside. Instead it handles plain documentation files with sections and other constructs (like Texinfo or LaTeX) and inserts pieces of generated code documentation on request. Thus it does not enforce any way of structuring your document. It has been designed to parse advanced C++ constructs including class inheritance, template specialization, and template instantiation. XHTML, Texinfo, LaTeX, and DocBook output formats are supported.
zpub is a server to collaboratively work on DocBook-based documentation. Editors modify the XML sources with their preferred editor and submit their changes via Subversion. zpub renders the files centrally to various output formats, optionally notifies other editors, provides an archive of all previous revisions of the document, and supports a simple sign-off workflow. The documentation and user interface is currently only available in German.
Thot takes as input text in a wiki-like format and outputs results for different formats: HTML, Latex, DocBook, and PDF. Although delivered with only one input language (Dokuwiki format), Thot is very versatile and easy to extend. For example, the initial version allows you to embed a document description from different entities: source language, GraphViz DOT graphs, Latex math, etc.
The DocBook Authoring and Publishing Suite (DAPS) provides a tool set for easy creation and publication of DocBook sources on Linux. It lets you create HTML (including Webhelp), PDF, EPUB, man pages, and other formats with a single command. It automatically takes care of validating and filtering (profiling) your sources and automatically converts images into a format best suited for the output format. You can easily create profiled source tarballs for translation or review. DAPS supports authors by providing linkchecker, validator, spellchecker, and editor macros. It is well suited to manage large documentation projects with multiple authors using the DAPS docmanager.
Oxygen XML Developer is an Oxygen distribution specially tuned for XML development, providing XML editing, XML conversion, XML Schema development, XSLT/ XQuery/ XPath execution and debugging, SOAP and WSDL testing, Native XML and relational database support, and XML instance generation.
RTextDoc is a text editor with proofreading. It is designed for typesetting professional research papers and manuals using the LaTeX, AsciiDoc, and DocBook markup languages. It includes on-the-fly spelling and grammar checking, syntax highlighting, bracket matching, folding, a document structure browser for sections and labels, bookmarks, a manager for LaTeX symbols, WYSIWYG equation editor, and integrated BibTex database manager.
