I know that there are some emacs packages in Guix already, whi= ch doesn't use emacs-build-system, but I think we should keep that num= ber as low as possible and ideally to make it equal to 0 =3D) =20=20=20=20=20=20=20=20 If I do: guix install emacs-next notmuch then there is no guarantee that =E2=80=9CM-x notmuch=E2=80=9D will work. B= ecause =E2=80=99notmuch.el=E2=80=99 is byte-compiled using =E2=80=99emacs-no-x=E2= =80=99. The issue is that some Emacs packages rely on =E2=80=99emacs-minimal=E2=80=99, others on =E2= =80=99emacs-no-x=E2=80=99 as input, others on other Emacs VM variant, therefore the transformation guix build -m manifest.scm --with-input=3Demacs-minimal=3Demacs-next will not work, as pointed by Nicolas here [1]. Well, you will tell me that =E2=80=99outputs=E2=80=99 does not change much the issue. :-) For sure= , but IMHO having Emacs packages using =E2=80=99emacs-build-system=E2=80=99 eases the = write of generic transformation. Well, there is enough corner cases with Emacs packages using =E2=80=99emacs-build-system=E2=80=99 which rewriting their = =E2=80=99#:emacs=E2=80=99 argument. Other speaking about Emacs packages using other build systems. Another point is, if I want to build =E2=80=99notmuch=E2=80=99 but I am not= an Emacs user, then: guix environment notmuch will download =E2=80=99emacs-no-x=E2=80=99 for nothing. When my network is= poor, I am unhappy. Although, it is already the case. :-) Well, this is something known, see: I am not convinced that several outputs help. And generally speaking, personally, I tend to prefer package inherit over several outputs. Matter of taste I guess. :-) Without speaking about cross-compilation. ;-) >From my point of view, I would split the package =E2=80=99notmuch=E2=80=99 = and propagate this new =E2=80=99notmuch=E2=80=99 package with a new =E2=80=99emacs-notmuc= h=E2=80=99 (if =E2=80=99notmuch.el=E2=80=99 requires it). Well, from my point of view, it would be how to improve the situation. :-) All the best, simon 1:
