erbtex will act just like pdflatex except that it will process ruby fragments between {: and :} markers, greatly expanding the ability to generate automated TeX and LaTeX documents.

Implements a Period class as a Range of Dates.

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.

Labrat is a linux command-line program for quickly printing labels. Labrat uses the wonderful Prawn gem to generate PDF files with label formatting in mind. With labrat properly configured, printing a label is as simple as: $ labrat 'Income Taxes 2021 ~~ Example Maker, Inc.' And you will get a two-line file-folder label with the text centered. It can print on dymo label printer rolls or Avery sheet labels. It knows the layout of most Avery label types. For Emacs users, labrat includes elisp code for invoking labrat from within a buffer, providing a quick way to print labels.

A set of classes for legal document elements such as Document, Case, Lawyer, Party, Court, Judge, etc. Made to play well with the ydl and erbtex gems.

Ydl provides a way to supply a ruby app with initialized objects by allowing the user to supply the data about the objects in a hierarchical series of "data definition files" with the extension .ydl.
