Hello, I've written a simple module:
(define-module (popgen popgen))
(export popgen)
(use-modules (ice-9 format))
(define *numprec* "~10,8,,,0f ")
(define *numformat* (string-append "~{" *numprec* "~}~%"))
(define (popgen popfun data)
;; POPFUN is a function that evaluates the vector DATA to yield the
;; next generation's data; print the data to the terminal and then
;; check the result of evaluating (popfun data); if the new vector
;; is close enough to the old one, exit and return #f; otherwise
;; call (popgen POPFUN (POPFUN DATA))
;;
;; First print the data to the current-output-port (user routines
;; may want to modify this to send the data down a pipe)
(format #t "~{~}~%" num-format (vector->list data))
(let* ((new (popfun data))
(diff (eudiff (new data))))
(cond ((< diff 1e-15) #f)
(else (popgen popfun new)))))
(define (eudiff vec1 vec2)
(sqrt (apply
+
(map (lambda (x y)
(* (- x y) (- x y)))
(vector->list vec1)
(vector->list vec2)))))
I'd like to test its features at the REPL, but I am having serious
trouble loading it. I'm not sure if the problem is in the definition or
how I'm loading it.
I get the following behavior:
guile> %load-path
("/usr/share/guile/site" "/usr/share/guile/1.8" "/usr/share/guile")
guile> (set! %load-path (cons (getcwd) %load-path))
guile> %load-path
("/home/joel/Documents/ss_theory/scm" "/usr/share/guile/site"
"/usr/share/guile/1.8" "/usr/share/guile")
guile> (use-modules (popgen popgen))
Backtrace:
In standard input:
76: 0* (use-modules (popgen popgen))
76: 1 (eval-case (# # *unspecified*) (else #))
76: 2 (begin (process-use-modules (list (list #))) *unspecified*)
In unknown file:
?: 3* [process-use-modules (((popgen popgen)))]
<unnamed port>: In procedure process-use-modules in expression
(process-use-modules (list #)):
<unnamed port>: no code for module (popgen popgen)
ABORT: (misc-error)
Where am I going wrong?
Thanks,
Joel
