Today's Emacs Lisp package tidy-up is of a package Ifirst wrote a couple of employersago. While working on code I oftenfound myself viewing FASTAfiles in an Emacs buffer and soI thought it would be fun to use this as a reason to knock up a simple modefor highlighting them.fasta.el was the result.While I doubt it was or is of much use to others, it helped me betterunderstand simple font-locking in Emacs Lisp, and also made some bufferslook a little less boring when I was messing with test data.As for this update: it's the usual stuff of cleaning up deprecated uses ofsetf, mostly.If bioinformatics-related Emacs Lisp code written bya non-bioinformatician is your thing, you might also find2bit.el of interest too. Much likefasta.el it too probably doesn't have a practical use, but it sure was funto write and taught me a few things along the way; it also sort of goeshand-in-hand with fasta.eltoo.
