Description

During the last year, the LaTeX backend in Org mode has received an overhaul. The objectives, while keeping backward compatibility, were:

  • Better integration of the font-management features and packages with lualatex/xelatex
  • Reducing the amount of #+LATEX_HEADER: lines and avoiding to have to include a pure LaTeX file to profit from them
  • Flexibility, while using native Emacs Lisp features, like file/directory local variables

In this talk, I will present the new font management features in the LaTeX backend and show a couple of examples of what can be achieved.

About the speaker:

After 30 years using Emacs, professionally and for my PhD, I'm currently quite involved in org-mode, where I'm revamping the LaTeX backend.
