Hello again,
I managed to find a solution, which seems to work.
I have created a file init.scm with the following content:
(define command-line-args '())
(define parse-argument-list
(lambda (arg-list)
(set! command-line-args
(if (null? arg-list)
(list)
(cdr arg-list)))))
(set-command-line-parser! "args" parse-argument-list)
In this way, when the command line option --args is found, the function
parse-argument-list is invoked.
I have loaded this file into the mit-scheme interpreter and saved a world image
(init.com) using the procedure disk.save.
I have then written a shell script (bash) that invokes my main Scheme script as
follows:
mit-scheme --band "init.com" --interactive --batch-mode --args $* <
myscript.scm
Finally, in my main script I can access the command line arguments through the
variable
command-line-args
I hope this is the standard / correct way to do this.
Best regards
Giorgio
