This is in reference to guile-2.0.11.

The (ice-9 getopt-long) module does not provide a process for accessing multiple command line arguments.

A patch for ice-9/getopt-long.scm  is attached which adds the procedure getopt-ref/many to access multiple argument values.

The following program and results illustrate the use of the current getopt-ref and the proposed getopt-ref/many:

mwette$ ./gotest.scm -f foo1 -b bar1 -f foo2 baz1 baz2
program arguments:
("./gotest.scm" "-f" "foo1" "-b" "bar1" "-f" "foo2" "baz1" "baz2")

getopt using option-ref:
foo: "foo2"
bar: "bar1"

getopt using option-ref/many:
foo: ("foo1" "foo2")
bar: "bar1"


where

mwette$ cat gotest.scm 
#!/opt/local/bin/guile
!#
(use-modules (ice-9 getopt-long))

(define spec
 '((foo (single-char #\f) (value #t))
   (bar (single-char #\b) (value #t))))

(let* ((args (program-arguments))
       (opts (getopt-long args spec)))
  (simple-format #t "program arguments:\n")
  (simple-format #t "~S\n" args)

  (simple-format #t "\ngetopt using option-ref:\n")
  (simple-format #t "foo: ~S\n" (option-ref opts 'foo #f))
  (simple-format #t "bar: ~S\n" (option-ref opts 'bar #f))

  (simple-format #t "\ngetopt using option-ref/many:\n")
  (simple-format #t "foo: ~S\n" (option-ref/many opts 'foo #f))
  (simple-format #t "bar: ~S\n" (option-ref/many opts 'bar #f))
  )
