What about modifying ‘guix’ package to make various "View graph" actions
in "M-x guix" work by default (without installing graphviz)?

I would rather change Guix itself: What about adding ‘guix-dot-program’
to guix-config.el.in, set to "@DOT_USER_PROGRAM@" (which doesn’t exist
yet)?
We can’t use @DOT@ because currently it is set to something like:
DOT='${SHELL} /home/ludo/src/guix/build-aux/missing dot'
So we need an AC_PATH_PROG for dot that defines the ‘DOT_USER_PROGRAM’
substitution variable.
Does that make sense?
Thanks,
Ludo’.

Great idea! However I think instead of moving ‘guix-dot-program’ to
"guix-config.el.in", it is better to move ‘guix-guile-program’ to
"guix-external.el" instead (explained below).

Yes, that's why I didn't use @DOT@, and decided to modify the ‘guix’
package instead.

Yes, this is great! I didn't think to go this way, thanks!
Along with the patch for this change, I'm also attaching a patch to
"improve" guix-config.el: to make all its constants begin with
"guix-config-" prefix and to use them in the real variables that may be
modified by a user. WDYT?

“at configure time”
The docstring should mention that it can be the empty string.
Alternately, ‘configure’ could set DOT_USER_PROGRAM to “dot” when it’s
not found, which I think is ever preferable. WDYT?

Thus here we’d be checking whether ‘guix-config-dot-program’ is an
absolute file name.

IMO an empty string is preferable (explained below), so I would like to
leave it like this (with an improved docstring as you pointed), if you
don't mind.

I think (executable-find "dot") is more reliable than just "dot" which
may not exist. So if there is no "dot" program, then ‘guix-dot-program’
variable will be set to nil. And once "dot" will be needed, a user will
get a useful (I hope) emacs error that "dot" is missing (it is handled
by ‘guix-dot-arguments’ function). While with just "dot" as you
suggest, there will be some unpleasant error in Guix REPL (it will
happen in ‘pipe-guix-output’ proc in “emacs/guix-main.scm”).

Agreed! I was just saying that an empty string is odd, and that setting
it to ‘dot’ would be aesthetically more pleasing.
So the only different is that the above would become:
(defcustom guix-dot-program
(if (absolute-file-name-p guix-config-dot-program)
guix-config-dot-program
(executable-find "dot")))
Does it make sense?

Not for me, but OK.

Yes, now I see what you mean. I still prefer an empty string, but I
don't mind the variant you suggest. The updated patch is attached,
thanks!
