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 . 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.
