Hi

Found another error :p

This time after installing guile-readline it is not imediately available 
to guile even though it is available in the path. Weird.

Install:

sdb <at> komputilo ~$ guix package -i guile-readline 
--substitute-urls=http://berlin.guixsd.org
The following package will be installed:
   guile-readline    2.2.3 
/gnu/store/i0nqs30zn0bdij5zwagqx1chcdk460ai-guile-readline-2.2.3

Hello,

Rather you need:

  export GUILE_LOAD_PATH=~/.guix-profile/share/guile/site/2.2:$GUILE_LOAD_PATH
  export GUILE_LOAD_COMPILED_PATH=~/.guix-profile/lib/guile/2.2/site-ccache:$GUILE_LOAD_COMPILED_PATH

Better yet, you can install both ‘guile’ and ‘guile-readline’ in the
same profile and you’ll get a message telling you what to do:

--8<---------------cut here---------------start------------->8---
$ guix package -p foo -i guile guile-readline

[...]

La jenaj medi-variablaj difinoj povos esti necesaj:

HTH!

Thanks for the tip! I only installed guile-readline and it did not emit 
any environment variable suggestions.

Could we make all guile-* packages emit this suggestion?

This limitation is the same as <https://bugs.gnu.org/22138>.

Alas, no good solution have surfaced.  Perhaps we need a
"propagated-search-paths" package record or similar?

It’s actually a different issue here: the profile contains packages that
provide share/guile/2.2, but the same profile doesn’t contain any
package that “claims” share/guile/2.2.  Thus, everything is working
according to plan, so to speak.

I understand this particular case is confusing though.  It’s confusing
because Guile is already installed, albeit in another profile.

What we could do to avoid this confusion is pre-define GUILE_LOAD_PATH
and GUILE_LOAD_COMPILED_PATH in /etc/profile, just like we do for
INFOPATH et al.

WDYT?

Sounds good to me.

What I am after is lowering the bar for the user to learn and use guile 
and readline seems like a pretty important component to avoid typing 
everything over and over.

We want guix to be guile land and for guile land to be nice and welcome 
out the box.

I therefore suggest also adding guile-readline to %base-packages if it 
does not produce too much overhead.

Cheers
Swedebugia
