Hello Guix!

ludo@gnu.org (Ludovic Court=C3=A8s) skribis:

That was done a while back.   :-)

=E2=80=A6 and also the C++ bits.

With the work done in <https://bugs.gnu.org/27284>, we can build all of
Guix and its dependencies when doing =E2=80=98guix pull=E2=80=99, which bri=
ngs us closer
to what the =E2=80=98guix=E2=80=99 package provides.

Thus we can at least partly address the issue described in
<https://debbugs.gnu.org/cgi/bugreport.cgi?bug=3D22629#10>, i.e., have
=E2=80=98guix pull=E2=80=99 install not just a bunch of .go files but also =
guile-git,
guile-ssh, gnutls, and Guile itself.

To do that, we need a =E2=80=9Cparadigm shift=E2=80=9D (sounds cute, no? :-=
)).
Currently, =E2=80=98scripts/guix=E2=80=99 fiddles with its %load-path and a=
dds
~/.config/guix/latest if it exists.  The new =E2=80=98guix pull=E2=80=99 sh=
ould provide
not just .go files but also a =E2=80=98guix=E2=80=99 command referring to t=
he latest
Guile, Guile-Git, etc.

To achieve this, I think the new approach would be to have:

  export PATH=3D$HOME/.config/guix/current/bin:$PATH
  export INFOPATH=3D$HOME/.config/guix/current/share/info:$INFOPATH
  =E2=80=A6

=E2=80=98guix pull=E2=80=99 would update ~/.config/guix/current, which woul=
d contain the
=E2=80=98guix=E2=80=99 command, all the .go files, locales, the Info manual=
, and ideally
=E2=80=98guix-daemon=E2=80=99 as well.

~/.config/guix/current could be a profile, or something that resembles a
profile.

For a while =E2=80=98guix pull=E2=80=99 will have to keep updating ~/.confi=
g/guix/latest
as well, for users running an old =E2=80=98guix=E2=80=99 command.

Thoughts?
