tbibtools provide a simple regexp-based BibTeX parser that can be used to sort bib files, reformat bib files, list keys in a bib file, and show bib entries matching a regular expression. It is available as both a script and a VIM plugin. It makes a few assumptions about how a bib file should look like.
Rextile allows you to build XHTML documents and entire Web sites with ease. You write text using Textile (a format much more concise than XHTML), automate document parts with Ruby scripting, and generate the site offline (the server gets static XHTML). Rextile was inspired by Xilize. It uses RedCloth to convert Textile to XHTML, erb to run script blocks, and Hpricot for DOM manipulation.
Tartan is a text parsing engine targeted at wiki text. The syntax specification is defined in YAML in the form of regex-based rules. It supports layering and multiple output types. Rules for Markdown to HTML are included, with optional layered extensions for tables. It is implemented in Ruby, but looking to have implementations in other languages.
Rcss implements CSS-SSC (CSS Server-Side Constants) in Ruby. Its features include the processing of rich CSS files using ERB templates, server-side constants, and server-side classes (preliminary). It plugs-in seamlessly to any Rails application but also allows the processing of Rcss files off-line using a command line executable.
SiSU (Structured information, Serialized Units) is a lightweight markup based, text structuring and publishing framework (that features granular search). With minimal markup of a plaintext file, it produces: plain-text, HTML, XHTML, XML, ODF, LaTeX, PDF, and populates an SQL database at an object/paragraph level for granular searches. Prepare documents using your text editor of choice, then use SiSU to generate the desired output formats. SiSU is controlled from the command line.
AntFlow builds upon Apache Ant to provide a new approach to simplifying system automation that uses pipelines of hot folders chained together to perform a given task. Using XML, it associates an automated task such as data transfer, encryption, or XML processing with a directory on the local system. Whenever a file is copied or written into the hot folder, the associated task is executed and the file is moved to the next hot folder in the pipeline for further processing.
deplate converts wiki-like markup to LaTeX (standard classes, koma, dramatist, sweave), HTML/PHP (single page, chunked/website, HTML, or s5-based slideshow), DocBook (article, book, man/ref page), and really plain text. Currently supported input formats are viki and Ruby's rdoc. The viki markup supports footnotes, citations, index, table of contents, embedded LaTeX for mathematics, integration with R for dynamically generated figures and tables, and more. Output can be customized via page templates.
