LaTeX

Compared to some other emacs configurations, it is very easy to get useful LaTeX features (like SyncTeX and XeTeX) working with Prelude. Simply add the following lines into a .el file in your personal config directory (which is probably ~/.emacs.d/personal/).

For example, you could make the file ~/.emacs.d/personal/latex.el.

XeTeX

(setq-default TeX-engine 'xetex)

SyncTeX

(setq TeX-source-correlate-mode t)

(On Fedora 21 GNOME version, this will get you a wonderfully working setup with Evince.)
