For those new to it, TeX is a programming language that you use to create typeset documents rather than computer software. TeX is quite archaic in some ways, but it’s still the tool of choice for documents that require precision typography or ones that involve lots of mathematical equations, which makes it especially important in the sciences. Tectonic converts TeX files into PDF files. What’s in it for me? Tectonic automatically downloads support files so you don’t have to install a full LaTeX system in order to start using it. If you start using a new LaTeX package, Tectonic just pulls down the files it needs and continues processing. The underyling “bundle” technology allows for completely reproducible document compiles . Thanks to the Dataverse Project for hosting the large LaTeX resource files! Tectonic has sophisticated logic and automatically loops TeX and BibTeX as needed, and only as much as needed.…
