IIRC, emacs{-minimal} have about ~300 non-Elisp dependents, which IMO is
OK for master (Elisp packages are very cheap to build, so I don't count
them).
I've just verified this with the following script:
--8<---------------cut here---------------start------------->8---
(use-modules (gnu packages)
(guix graph)
(guix monads)
(guix packages)
(guix store)
(guix scripts graph)
(guix scripts refresh)
(gnu packages emacs)
(srfi srfi-1)
(srfi srfi-26))
(define (all-packages)
"Return the list of all the distro's packages."
(fold-packages (lambda (package result)
;; Ignore deprecated packages.
(if (package-superseded package)
result
(cons package result)))
'()
#:select? (const #t)))
(define (packages->dependents packages)
(define (full-name package)
(string-append (package-name package) "@"
(package-version package)))
(with-store store
(run-with-store store
(mlet %store-monad ((edges (node-back-edges
%bag-node-type
(package-closure (all-packages)))))
(let ((dependents (node-transitive-edges packages edges)))
(return (map full-name dependents)))))))
(define (compute-results)
(let* ((dependents (packages->dependents (list emacs emacs-minimal)))
(non-emacs (remove (cut string-prefix? "emacs-" <>) dependents)))
(format #t "Emacs{-minimal} have ~d dependents, ~d of which are not pure \
Emacs libraries: ~a~%" (length dependents) (length non-emacs) non-emacs)))
(compute-results)
--8<---------------cut here---------------end--------------->8---
Which outputs:
Emacs{-minimal} have 973 dependents, 274 of which are not pure Emacs
libraries: (faust@2.5.23 cedille@1.1.1 cflow@1.6
