This is a great feature, but I found a tricky failure:
------
$ ./pre-inst-env guix system vm --no-grafts doc/os-config-bare-bones.texi --substitute-urls=https://ci.guix.gnu.org -d
guix: system: command not found
hint: Did you mean `system'?
Try `guix --help' for more information.
$ guix environment guix
$ ./pre-inst-env guix system vm --no-grafts doc/os-config-bare-bones.texi -d
/gnu/store/pw453xpixcll02w1nz9mfggm2cn0jqpx-run-vm.sh.drv
------
It will only be seen by developers, so not a big deal, but it would
still be nice to correctly report which command is missing. Some
run-time dependency of guix is missing.

I am missing, because the command line is not wrong. :-)
Well, I am missing what you are suggesting. I mean if “./pre-inst-env
guix <foo>” is run in an incorrect environment, then, I am not sure what
could be done. How does it work with a commit which predates the hint
introduction? How does it fail? I guess it fails, if not I am missing
something. :-)
Basically, when “guix system” is called (or any other command), it
enters in ’run-guix-command’ and does this snippet:
--8<---------------cut here---------------start------------->8---
(catch 'misc-error
(lambda ()
(resolve-interface `(guix scripts ,command)))
(lambda _
(let ((hint (command-hint command (commands))))
(format (current-error-port)
(G_ "guix: ~a: command not found~%") command)
(when hint
(display-hint (format #f (G_ "Did you mean @code{~a}?")
hint)))
(show-guix-usage)))))
--8<---------------cut here---------------end--------------->8---
Therefore, it means that “(resolve-interface `(guix scripts ,command))”
fails for some reasons. It seems really hard to catch the reasons.
Well, this cannot happen with regular “guix <foo>” otherwise it is
severe bug. And in a developer setup, so much stuff could be wrong.
Well, these run-time dependencies could be checked by the script
“./pre-inst-env” but I do not know if it is worth.
Could you explain more what you would like?
On a side note, trying I get that the hint seems to work…
--8<---------------cut here---------------start------------->8---
$ guix system vm --no-grafts ~/src/guix/guix/doc/os-config-bare-bones.texi --substitute-urls=https://ci.guix.gnu.org --dry-run --derivatio
guix system: error: derivatio: unrecognized option
hint: Did you mean `derivation'?
--8<---------------cut here---------------end--------------->8---
…but not work for all the options:
--8<---------------cut here---------------start------------->8---
$ guix system vm --no-grafts ~/src/guix/guix/doc/os-config-bare-bones.texi --substitute-rls=https://ci.guix.gnu.org --dr-run --derivation
guix system: error: substitute-rls=https://ci.guix.gnu.org: unrecognized option
--8<---------------cut here---------------end--------------->8---
Another story than your report, right?
Cheers,
simon
