be well recorded and in theory safe and secure, Qi is completely documented, with official accuracy proofs and has a canonical book which is also online. Qi makes use of the rational notation of sequent calculus to specify types. This type notation, under Qi's interpretation, is actually a Turing total language in its own right.

Qi compiles sequent calculus to Qi Prolog (which is integrated into the Qi environment) by means of the Abstract Unification Machine (AUM). The AUM functions as a functional programming analog to the Warren abstract machine generating virtual instructions from what is basically an extended lambda calculus. The Qi compiler maps AUM directions to Typical Lisp, and these the Lisp compiler compiles into byte code or device code depending on the Lisp platform.

Qi is therefore bootstrapped or composed (largely) in itself apart from a few Typical Lisp functions. As of January 2009, Qi has actually been upgraded several times given that the first release (6. 1) in April 2005, and the current release, Qi II 1. 07, launched in July, 2009, runs under both Windows and Linux on the CLISP, CMU Common Lisp, Allegro Common Lisp and Steel Bank Common Lisp (SBCL) platforms.

Prior to this, an earlier version, 9. 0, incorporated an optional factoring code compiler (Turbo-E) for optimising pattern-matching. In a comparative shoot-out against a number of Lisp programs and Objective Caml, Qi 9. 0 performed at the speed of the fastest and most greatly hand-optimised Lisp variation. A release (Qi/Tk) including a type secure variation of Tcl/Tk embedded into Qi appeared in March 2009.

The brand-new variation is developed to run under Common Lisp, Clojure and Python and is likewise targeted for the Dalvik Virtual Device. Contributors consist of Dr Mark Tarver, Carl Shapiro of Google and Stefan Tampe. Additionally, the developers and proponents of the concepts stated in Qi, have actually created a successor to Qi, called Shen (Shows Language).
