Consider following example using this definition of package--get-deps:
--8<---------------cut here---------------start------------->8---
(defun package--get-deps (pkg &optional only)
(let* ((pkg-desc (cadr (assq pkg package-alist)))
(direct-deps (cl-loop for p in (package-desc-reqs pkg-desc)
for name = (car p)
when (assq name package-alist)
collect name))
(indirect-deps (unless (eq only 'direct)
(cl-loop for p in direct-deps
append (package--get-deps p 'direct)))))
(cl-case only
(direct direct-deps)
(separate (list direct-deps indirect-deps))
(indirect indirect-deps)
(t (append direct-deps indirect-deps)))))
--8<---------------cut here---------------end--------------->8---
Here the dependencies of the package "jedi":
(package--get-deps 'jedi 'direct)
=>(epc auto-complete python-environment)
(package--get-deps 'epc 'direct)
=>(concurrent ctable)
(package--get-deps 'concurrent 'direct)
=>(deferred)
(package--get-deps 'ctable 'direct)
=>nil
(package--get-deps 'auto-complete 'direct)
=>(popup)
(package--get-deps 'python-environment 'direct)
=>(deferred)
(package--get-deps 'jedi)
=>(epc auto-complete python-environment concurrent ctable popup deferred)
As you can see all the dependencies are here and there is no duplicates.
