hi, i have a main Scheme+ module that exports an overload macro: (define-module (Scheme+)
#:use-module (growable-vector) #:use-module (ice-9 local-eval) #:use-module (ice-9 match) #:use-module (srfi srfi-1) ;; any,every #:use-module (srfi srfi-69) ;; Basic hash tables #:use-module (srfi srfi-31) ;; rec #:use-module (srfi srfi-26) ;; cut #:export (!*prec set-infix-operators! overload overload-procedure overload-operator overload-function $nfx$ def $bracket-apply$ <- ← -> → <+ ⥆ +> ⥅ declare $> $+> condx ≠ ** <v v> ⇜ ⇝ repeat % << >> & | ) ... code cut ... (include-from-path "overload.scm") ... the overloads macros defined in overload.scm like that: (define-syntax overload (syntax-rules () ;; arguments are symbol of function to be overloaded, procedure that do the overloading, list of predicate to check the arguments ((_ funct-symb proc (pred-arg1 ...)) (overload-procedure funct-symb proc (pred-arg1 ...))) ((_ funct-symb proc (pred-arg1 ...) quote-operator) (begin (overload-operator funct-symb proc (pred-arg1 ...)) (update-operators)) ) ((_ funct-symb proc (pred-arg1 ...) quote-operator quote-n-arity) (begin (overload-n-arity-operator funct-symb proc (pred-arg1 ...)) (update-operators))))) i just show one macro of file and a program that use the Scheme+ module and overload macro: (use-modules (Scheme+) .... (include "guile/logiki+.scm") finally logiki+.scm use overload: (initially overload.scm was included from here and it worked well but now it is in Scheme+ it gives the error in subject) ;; overload tests (define (add-pair p1 p2) (cons (+ (car p1) (car p2)) (+ (cdr p1) (cdr p2)))) (overload + add-pair (pair? pair?) 'operator) ;; line 4818 (define (mult-num-vect k v) (map (λ (x) (* k x)) v)) (overload * mult-num-vect (number? list?) 'operator) {t <+ {3 * '(1 2 3) + '(4 5 6) + '(7 8 9)}} (display t) (newline) when run i have this error: scheme@(guile-user)> (load "start-λογικι-guile+.scm") ;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0 ;;; or pass the --no-auto-compile argument to disable. ;;; compiling /usr/local/share/guile/site/3.0/Scheme+.scm ;;; compiling /usr/local/share/guile/site/3.0/growable-vector.scm ;;; compiled /Users/mattei/.cache/guile/ccache/3.0-LE-8-4.6/usr/local/share/guile/site/3.0/growable-vector.scm.go ;;; compiled /Users/mattei/.cache/guile/ccache/3.0-LE-8-4.6/usr/local/share/guile/site/3.0/Scheme+.scm.go ice-9/boot-9.scm:1685:16: In procedure raise-exception: Wrong type to apply: #<syntax-transformer overload> Entering a new prompt.
