Org and Beamer
A few days ago, I decided to rewrite a MArkdown template that I occasionally use for talks or courses. Part of this has already been discussed in an another post. Since I always found Org documents better than Markdown ones, I wanted an Org template much like I have a template for short handouts. I followed the same idea and I created a small shell script that I call from a terminal or from a Vim shortcut:
#!/usr/bin/env bash
FILE=$1
ELISP="/home/chl/Documents/notes/assets/org-beamer.el"
emacs --batch -l "$ELISP" --eval "(progn (find-file \"$FILE\") (org-beamer-export-to-pdf))"
The org-beamer.el file holds all the default settings I wish to use. I changed things a bit, especially the main fonts. I could use xelatex or lualatex as before, but after all Bitstream Vera is a nice sans serif font, and it comes with builtin math support thanks via the arev package. My Emacs Lisp setup file now basically reads: (I skipped basic settings and org-babel related stuff.)

After having reviewed the new features of Context I do not exclude the idea of returning to pure tex slides soon, though. I still have some handouts to read.
