guix package -u . --dry-run equivalent for guix home

guix package -u . --dry-run equivalent for guix home

[Remco van 't Veer]

Hi,

Before using guix home, I had a manifest file for all my packages.
Whenever I did a "guix pull", I'd do "guix package -u . --dry-run" to
figure out if anything interesting got updated.  How do I do that when
my manifest is in my home configuration?  Using "--dry-run" on "guix
home reconfigure" only tells me how much will be downloaded.  I tried
tricking "guix package" into telling me with "guix package -p
.guix-home/profile -u . --dry-run" but that gets me an error.

Is it possible to get an package update dry-run like output for guix
home?

Cheers,
Remco

I'll run 'guix home build <path-to-file> -n' to see what's going to be
built.

That's a bit more informative but currently it only tells me it's going
to download some new version of guix.  Running build without -n reveals
it will download and install a lot more..

How are people (with update junky tendencies like me) using guix-home?
Run guix-home-reconfigure after every guix-pull?

Ok, I admit that isn't the full command.

guix home build <path-to-file> --no-grafts -n'

The '--no-grafts' means it'll give an accurate response of what will be
built/downloaded without taking into account any new grafts.

I also normally add '--fallback' with 'guix home build' to try again if
a download fails.

I in general just check the commit messages in the range that was pulled to see
if there is anything interesting.  And reconfigure only in that case.

Yes, that's a lot closer to what I want to see.  Slightly better even!

Thanks,

Yeah, I have guix master from savannah in a RSS reader but miss a lot
because it only returns the latest 10 commits.  Do your have a local
clone to get the logs from or is their some trick to get the logs from
the commits guix-pull just fetched?

Right so the thing is I do not run stock Guix, but a fork with some (very) light
modifications.  So I need to merge updates from the Guix proper periodically.
And those merge commits are configured to provide in the commit message the very
information I need:

    https://git.sr.ht/~graywolf/guix/commit/96ffe69d09c7abd4a80b632eb53c064e97e62141

> or is their some trick to get the logs from the commits guix-pull just

When `guix pull'-ing, it gives you a message like this:

    Authenticating channel 'guix', commits 028e445 to 32c6a3a (9 new commits)...

So I would just use `git log --oneline 028e445..32c6a3a' in the Guix repository
(which I do have local clone anyway) to get the same list I have in the commit
message right now.

Hope this helps,
Tomas

Thanks, that is very helpful.  I'll script something to compare the
commit delta between guix-describe and guix-home-describe on my local
clone or doing log range on savannah.
