Usage of interactive shell ptq

% ptq
PTQ> John seeks a unicorn.
Parsed:
  F4 john (F5 seek (F2 a unicorn))

Translation:
  (\x0. x0 {john}) (Int (seek (Int ((\x0. \x1. exists x2. x0 {x2} && x1 {x2}) (Int unicorn)))))

Translation (simplified):
  seek (Int (\x0. exists x1. unicorn x1 && x0 {x1})) john

------------------------------------------------------

Parsed:
  F10 0 (F2 a unicorn) (F4 john (F5 seek (He 0)))

Translation:
  (\x0. \x1. exists x2. x0 {x2} && x1 {x2}) (Int unicorn) (Int (\x0. (\x1. x1 {john}) (Int (seek (Int (\x1. x1 {x0}))))))

Translation (simplified):
  exists x0. unicorn x0 && seek (Int (\x1. x1 {x0})) john

CGI interface

By locating ptq.cgi, cgi/index.html and cgi/main.html to the place where CGI is executable, you can try it on the web. Demo site runs at http://www.tom.sfc.keio.ac.jp/~sakai/hsPTQ/ (currently not working).

Haste interface

You can use Haste to compile haste/* and run on your browsers. Demo site runs at http://msakai.github.io/ptq/demo/index.html.
