tptp-el: Hack TPTP with emacs and SubEthaEdit
Do you work with formal proofs in plain first-order logic? In Emacs? If you said "yes" to both questions, this package is for you.
Currently, the TPTP Emacs Lisp package consists of a single Emacs Lisp file, namely this one, tptp.el. Simply put tptp.el in a directory (I recommend "~/share/emacs/site-lisp/tptp", but it doesn't really matter), and in your Emacs initialization file (generally the file called ".emacs" in your home directory), add the form
(add-to-list 'load-path <path to the directory in which you put tptp.el>) (require 'tptp)
Make sure the path is double quoted, e.g., "/Users/jesse". For slightly better performance of the TPTP Emacs Lisp package, byte compile tptp.el.
To automatically load tptp-mode when editing files with a certain extension, add something like this to your Emacs initialization file:
(add-to-list 'auto-mode-alist '("\\.ax\\" . tptp-mode))
Doing this will set up files that have the ".ax" extension to automatically load tptp-mode. You can do this for multiple extensions (e.g., ".p", ".ax", etc).
There is currently only one prover supported for SubEthaEdit: vampire. To install SubEthaEdit support for vampire:
- Make a bin subdirectory of your home directory, if it doesn't already exist.
- Copy run-vampire.sh to ~/bin, and make the script executable.
- Copy run-vampire.applescript to ~/Library/Application Support/SubEthaEdit/Scripts.
Next time you start SubEthaEdit, you should see, in the Scripts menu, an item that says "Run Vampire". Try it out!

There you can get the latest bleeding edge development version of the package, as well as download choice releases.
Ed Zalta provided the impetus for launching this package.
