Emacs lisp

tempo.el

This is a package for creating templates. It is meant to be used be elisp programmers when creating sets of macros for inserting common structures, e g in programming modes. It has been part of GNU Emacs since version 19.23, but I usually have a newer version here.

The latest beta version
Some examples (C, C++ and elisp)
An incomplete Texinfo manual (but probably useful), and an info version of it.

turing.el

This is a Turing Machine implementation. I haven't worked very long at it, but it is starting to be useful.

lyskom-menu.el

This is a menu extension to lyskom.el. If you don't know what lyskom.el is, you will not need this.
