GEE/Infix version 0.4b0 is available.
<http://gna.org/projects/gee>
This version is tested with Guile 1.8.3.
GEE/Infix is a C language library extension for Guile, the
GNU's Ubiquitous Intelligent Language for Extensions. It
implements an infix->prefix notation converter for Scheme
code. It is derived from Guile-Arith, by Ian Grant
<iang/pobox.com>.
You can use GEE/Infix under the terms of the GNU General
Public License version 2, or (at your option) any later
version.
At present the conversion does no optimisations. Examples:
(infix->prefix "fun(1+a, sin(2), 3*g, 4+a+f+r+t)")
;; -> (fun (+ 1 a) (sin 2) (* 3 g) (+ (+ (+ (+ 4 a) f) r) t))
(infix->prefix "cos(a) * (tan(b) / c)")
;; -> (* (cos a) (/ (tan b) c))
SRFI-10 is used to implement a read syntax:
(let ((x 8.8)
(y 9.9))
#,(infix x^2 + y^3 -1))
is equivalent to:
(- (+ (expt 8.8 2) (expt 9.9 3)) 1)
Another extension of the language, I think.
