LaTeX Calendar Generator

December 23, 2015 by . Filed under code, public.

My wife is crafting together a calendar full of family photos, and she asked me to print off some simple 2016 calendar grids that she found online. I looked at the templates and vomited. They had URLs on them.

Because I suffer from developerism, I asked my wife if she’d let me try and generate some calendar pages for her. She agreed and even sat and watched me code up the script that I share below. She is rarely the direct benefactor of my career and skill set, and we will forever treasure this night when she watched me code up a calendar generator. Especially when we run it each year for the rest of our lives.

A page from the end results looks some like this:

The generator is written in Ruby and its output is LaTeX source, which can be fed into a LaTeX interpreter like pdflatex.
