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:

  1. Make a bin subdirectory of your home directory, if it doesn't already exist.
  2. Copy to ~/bin, and make the script executable.
  3. 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!

Ed Zalta provided the impetus for launching this package.
