Converts LaTeX math into MathML.

Latexpdf is a renderer for rails which compiles Tex files with ERB to a PDF using xelatex by default so that it supports Unicode.

Kramdown extension for math-heavy document. It provides theorem environments, and easy references to those environments as well as to equations and section headers. Moreover, a bibliography section can be generated from a BibTeX file, and an flexible and easy mean of citing bibliographical entries is provided. Sections and environments are automatically numbered.

BibTeX-Ruby is the Rubyist's swiss-army-knife for all things BibTeX. It includes a parser for all common BibTeX objects (@string, @preamble, @comment and regular entries) and a sophisticated name parser that tokenizes correctly formatted names; BibTeX-Ruby recognizes BibTeX string replacements, joins values containing multiple strings or variables, supports cross-references, and decodes common LaTeX formatting instructions to unicode; if you are in a hurry, it also allows for easy export/conversion to formats such as YAML, JSON, CSL, and XML (BibTeXML).

FatTable is a gem that treats tables as a data type. It provides methods for constructing tables from a variety of sources, building them row-by-row, extracting rows, columns, and cells, and performing aggregate operations on columns. It also provides as set of SQL-esque methods for manipulating table objects: select for filtering by columns or for creating new columns, where for filtering by rows, order_by for sorting rows, distinct for eliminating duplicate rows, group_by for aggregating multiple rows into single rows and applying column aggregate methods to ungrouped columns, a collection of join methods for combining tables, and more. Furthermore, FatTable provides methods for formatting tables and producing output that targets various output media: text, ANSI terminals, ruby data structures, LaTeX tables, Emacs org-mode tables, and more. The formatting methods can specify cell formatting in a way that is uniform across all the output methods and can also decorate the output with any number of footers, including group footers. FatTable applies formatting directives to the extent they makes sense for the output medium and treats other formatting directives as no-ops. FatTable can be used to perform operations on data that are naturally best conceived of as tables, which in my experience is quite often. It can also serve as a foundation for providing reporting functions where flexibility about the output medium can be quite useful. Finally FatTable can be used within Emacs org-mode files in code blocks targeting the Ruby language. Org mode tables are presented to a ruby code block as an array of arrays, so FatTable can read them in with its .from_aoa constructor. A FatTable table can output as an array of arrays with its .to_aoa output function and will be rendered in an org-mode buffer as an org-table, ready for processing by other code blocks.

ULMUL is an original Ultra Lightweight MarkUp Language. You can write TeX-style equations in ULMUL texts. The ULMUL texts can be converted into HTML5+MathML with ulmul2html5 command, into HTML5+MathJax with ulmul2mathjax and into LaTeX with ulmul2latex. You can also generate Slidy presentations. Its library ulmul.rb is written in Ruby.
