Hi !

I want to create a multi-layer file by reading from a txt file x/y position
and image name.

I've tried to read from file with code below

              (let* ((fd (fopen filename)))
                      (let*   (
                              (c (fread 1 fd))
                              (res "")
                      (while (and c (not (equal? c " ")))
                              (set! res (string-append res c))
                              (set! c (fread 1 fd)))
                              (if (equal? res "")
                                      (cons (string->number res) ())
                      (gimp-message (string-append "PosX: " (number->string
res))) )

I do not understand why it returns :"Error: eval: unbound variable: res "

Could you help, please ?


Perhaps use python instead of scheme and use line-based i/o and
instead of byte by byte read.
