Hi Petter,
Try this:
(defun jde-import-strip-existing-imports (new-imports existing-imports)
"Exclude classes that have already been imported."
(delq
nil
(mapcar
(lambda (new-import)
(unless
(find
new-import
existing-imports
:test (lambda (new existing)
(let ((new-package (jde-parse-get-package-from-name new))
(new-class (jde-parse-get-unqualified-name new))
(existing-package (jde-parse-get-package-from-name existing))
(existing-class (jde-parse-get-unqualified-name existing)))
(and
(string= new-package existing-package)
(or
(string= new-class existing-class)
(string= existing-class "*"))))))
new-import))
new-imports)))
