Readme for PTQ-0.0.5

[back to package description]
= An implementation of Montague's PTQ in Haskell

== Build and Install

You'll need GHC 6.7 or later.

  % runhaskell Setup.lhs configure
  % runhaskell Setup.lhs build
  % runhaskell Setup.lhs install

== 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.
