[Clément Lassieur]

Hi,

The first patch allow one to package Gajim plugins.  It also removes two
inputs that were added for the OMEMO plugin.

The second add the OMEMO plugin.

Thanks,
Clément

Hmm, don't both of these hard-code one profile?  I thought one can use
any number of profiles - and this patch could definitely pick from the
wrong one.  Why isn't the PLUGINS_USER setting enough?  Can't it be
provided via environment variables?  (set by the profile)

Also, shouldn't PYTHONPATH already have been set by the profile?  For me,
it is set (to ~/.guix-profile/lib/python3.6/site-packages) when I log in.

I don't understand what this means.

What do you mean?  This patch just adds the Guix packaged plugins to the
list of plugin dirs.

> Why isn't the PLUGINS_USER setting enough?

Because it doens't know about Guix installed plugins.  It doesn't look
in ~/.guix-profile/whatever.  Only at /gnu/store/...-gajim/something and
~/.local/share/gajim/something.

> Can't it be provided via environment variables?  (set by the profile)

Gajim doesn't seem to support customizing plugin dirs through
environment variables, which is why I edited its code.

It shouldn't be in the profile if python isn't installed.

guix supports any number of profiles as one user, the ~/.guix-profile one is just
the default, you can create and select profiles at will.

You can specify any profile you want using the option "-p" to "guix package" -
also, "guix environment" will create a custom profile.

However, your patch hardcodes ~/.guix-profile which is in general not what a user
using "-p" would want.  I agree that it makes sense to search for the plugins in
the current profile, but it's not clear to me that ~/.guix-profile is always
guaranteed to BE the current profile.  Is it?

According to https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-environment.html#FOOT16 ,
fontconfig already hardcodes ~/.guix-profile and "guix environment" has a
special flag to fake it, so maybe (probably?) it's OK to use it after all.

I hope someone else can chime in - but this is what immediately caught my
eye because what's the use of all these environment variables if one
hard-codes ~/.guix-profile anyway - could have hard-coded it in all packages,
then...

In general that's OK.
