bug#37790: MANPATH missing from non-default profile

[Pierre Neidhardt]

`man` fails to find man pages from non-default profiles.
Indeed, MANPATH is set in /etc/profile to

export MANPATH=\
$HOME/.guix-profile/share/man\
:/run/current-system/profile/share/man

I believe that each profile should set MANPATH in their own etc/profile.

Thoughts?

As usual, ‘MANPATH’ is only defined when ‘man-db’ is also present in the
profile, since ‘MANPATH’ “belongs” to ‘man-db’.

HTH!

Indeed, but I'm suggesting we add an exception for the sake of
convenience and consistency:

- The default profile ~/.guix-profile is added, man-db or not.
- It's seems a bit unfortunate that all my profiles need to have man-db
  in it.

What do you think?

I agree it’s inconvenient, but how would you add an exception?

I'm not too sure how Guix works here, but what about when building the
profile, systematically populating etc/profile with MANPATH=...?

I don't think special casing ~/.guix-profile like this, polluting other
profiles is a good idea.

I'm closing this 2+ years old bug.

Thank you,

Maxim

From my understanding, it is a "bug" as explained here:

1: <https://issues.guix.gnu.org/37790#2>

Or at least an inconvenient behaviour. :-)

It appears to me the contrary, no?  That ~/.guix-profile is special here.

Well, using a multi-profiles style management, it appears to me
adequate to install "man" (or man-db) once, i.e.,  in one profile say
~/.cache/guix/profiles/utilities, and then install other packages, say
git, in another profile, say ~/, .cache/guix/profiles/tools, etc.

With the current design, each profile other than ~/.guix-profile
requires 'man-db' which seems unfortunate, non?

Sorry, I fail to see where is the bug :-).  This is our the search-path
specifications have always worked; they work per profile and are
attached to the application acting as the "consumer" of the environment
variable it sets.

If we want to work on improving this we already have the following
issues opened awaiting work:

20255 'search-paths' should respect both user and system profile.

and somewhat related:

22138 Search paths of dependencies are not honored

Thanks,

Maxim
