Hello, I tried to move (and rename for consistency with other ‘show-…’
procedures) ‘manifest-show-transaction’ from (guix profiles) to (guix
ui) as we were discussing on #guix today, but I found that tests began
to fail. And I can't figure it out. The first failed test is
"builders.scm". Its log and the patch with the changes I made are
attached.
Need help :(

Sorry, I've found that the patch I sent is not cleanly applied to the
latest master checkout. The modified patch is attached.
It seems the fail happens only if there is
#:use-module (guix profiles)
in (guix ui). If (guix profiles) is not used, there are no problems.
I'm stuck.

This is another circularity issue. :-/
There’s:
(guix store) -> (guix nar) -> (guix ui) -> (guix store) ...
This shouldn’t be a problem, except that occasional uses of #:select
trigger a bug (see <http://bugs.gnu.org/15540>.)
I’ve fiddled a bit on top of your patch, but couldn’t find any simple
fix.
However, back to the initial problem, is this a problem if the error
conditions are defined in (guix profiles), which is then imported by
(guix ui)? This is suboptimal, but this kind of circular reference
shouldn’t cause any troubles.
HTH,
Ludo’.

Ouch, thanks for the explanation.

Do you mean to "#:select" condition types in (guix ui)? I tried but it
failed for me even on “make” (the patch I tried and the make output are
attached). So it looks like even selecting from (guix profile) won't
work in (guix ui) or did I miss something?
What about making an auxiliary (guix conditions) module with all
existing condition types, and use it where needed? I could try to work
on it if it sounds reasonable. WDYT?

Hmm yes, but only as a last resort.
I’ve spent some time trying to better understand the problem, but failed
(we desperately need tools in Guile do to this sort of things.) Another
part of the problem is that (guix monads) uses other modules’ bindings
at the top-level.
Mark, any ideas?
Alex, is there a way we can backtrack a bit and move forward in the
meantime?

Commit 0363991 fixes that.
(Now we must make sure we don’t reintroduce cycles in these modules;
probably we should integrate Mark’s cycle detection script somehow.)
With that I was able to apply the patch you posted.
Thanks, and sorry for the mess!

Thank you for fixing that and sorry that I didn't reply to you on #guix
yesterday (I was away).
Now there shouldn't be problems with adding new condition types to (guix
profiles). The patch is attached and “make check” was successful on
that. 2 little questions:
1. As you suggested I made a hierarchy of conditions:

Thank you for the idea btw, I like it. So the question is: should the
parent &profile-error be handled as well? If yes, what message to use?
2. And another question: the current error for generation would look
like this:
generation 18 does not exist
Is it OK or should I use ‘generation-file-name’ there and make it:
generation '/some/path/to/profile/generation-18-link' does not exist
\f
The problem now is I can't add ‘switch-to-generation’ procedure to (guix
profiles) as it uses ‘_’ and ‘switch-symlinks’ from (guix ui) which is
not “#:use-module”-ed anymore. This patch is also attached. What to do
about it? I think moving ‘switch-to-generation’ to (guix ui) is not
good or is it? Perhaps it would be better to move ‘switch-symlinks’ and
all ‘_’, ‘N_’, … stuff to (guix utils)? But what do I know, it's up to
you again (I feel guilty that I have to bother you again).

I prefer “generation 18 does not exist”, or maybe “generation 18 of

Yeah, a you suggested on IRC, let’s just leave it in (guix scripts

I agree, mentioning a profile would be better. I modified the patch for
that.

OK, I have not pushed anything yet, as the commits were changed a bit.
I'm attaching all 3 patches for adding “Switch to generation” support.
Everything seems OK now (at least “make check” does not fail anymore),
so if you don't have final comments, I would like to commit them.
Thanks for the patience.

Thanks, pushed. Now I would like to add support for switching
generations from Emacs UI. The patches for that are attached.
Currently there is no way to see what generation is the current one –
the first patch will fix it (additional column is added to *Guix
Generation List*).
