be well documented and in theory safe, Qi is totally documented, with formal accuracy evidence and has a canonical book which is likewise online. Qi makes usage of the rational notation of sequent calculus to define types.  Need More Info? , under Qi's analysis, is in fact a Turing total language in its own right.

Qi puts together sequent calculus to Qi Prolog (which is included into the Qi environment) through the Abstract Unification Device (AUM). The AUM acts as a practical programs analog to the Warren abstract device generating virtual directions from what is essentially an extended lambda calculus. The Qi compiler maps AUM directions to Common Lisp, and these the Lisp compiler assembles into byte code or device code depending upon the Lisp platform.

Qi is thus bootstrapped or composed (largely) in itself apart from a couple of Common Lisp functions. As of January 2009, Qi has been updated a number of times since the very first release (6. 1) in April 2005, and the present release, Qi II 1. 07, released 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.

Our QI Path Statements

New license. Type safe lazy examination as needed. Enhanced programmable syntax. 4 speed compiler which uses type details. Improved combination with Common Lisp. Runs under Lisp, Functions. Common functions made polyadic. Enhanced connection to Prolog. Guideline closures for embedding sequent thinking into Qi functions. Enhanced dealing with on dependent types. A type safe class system in a library in addition to Functional Programming in Qi (2nd edition).

Before this, an earlier variation, 9. 0, integrated an optional factoring code compiler (Turbo-E) for optimising pattern-matching. In a comparative shoot-out versus several Lisp programs and Objective Caml, Qi 9. 0 performed at the speed of the fastest and most heavily hand-optimised Lisp variation. A release (Qi/Tk) including a type safe variation of Tcl/Tk embedded into Qi appeared in March 2009.

The new variation is designed to run under Common Lisp, Clojure and Python and is also targeted for the Dalvik Virtual Maker. Contributors include Dr Mark Tarver, Carl Shapiro of Google and Stefan Tampe. Alternatively, the developers and proponents of the concepts stated in Qi, have actually developed a follower to Qi, called Shen (Programming Language).
