Whizzytex on Ubuntu 7.10

Posted in Computers by Armchair Guy on July 28, 2008

Whizzytex is a pretty nifty application that updates a compiled TeX pane in real-time as you type into emacs. Under Ubuntu 7.10 it comes as a package in the repositories.

With my installation (on a Thinkpad t61) I’ve had an annoying problem: every few seconds, emacs will freeze completely for a 1-5 seconds (presumably doing a slice compilation or some such thing for whizzytex). This can happen right in the middle of a yank, and it can happen ten times a minute.

Here’s my solution, though I can’t explain why it works: put the line

(setq whizzy-load-factor 10)

in your .emacs file. The problem still occurs but very occasionally (once in 5-6 minutes, which I can live with). Whizzy is a lot more responsive now as well.

There is one downside: this really increases processor usage. My laptop runs hot and the battery doesn’t last long when I have the load factor set high this way.
