[gentoo-user] eix settings for searching all layman overlays

[Thanasis]

I would like to use eix and (updating it via cron job) be able to search
locally *all* layman overlays.
What commands and settings should I use?

The facts, although interesting, are usually irrelevant.

I don't have a local overlay, and the default path for layman overlays
is /var/lib/layman/<overlay>, so I guess I don't have to set the
LOCAL_LAYMAN variable, do I?

The problem is that after updating (by running the command eix-remote
update). I still don't get the results expected when doing a search, eg:

 # eix -l games-engines/spring
No matches found.

whereas it should list that there is a match in the sabayon (layman)
overlay (though not installed) like:

spring-88.0 ~amd64 ~x86

because, at least, the above is what I get by using the
http://gpo.zugaina.org/ search at
http://gpo.zugaina.org/games-engines/spring

So, I guess, I must be missing something in my eix configuration, don't
I? Besides, under /etc I only have /etc/eixrc/00-eixrc which is the
default (all lines in it are comments).

You  are trying to do something the software does not support.

eix will index your *installed* overlays, not all possible overlays that
could be out there. There is no way I know of to do that, and even if
there was a way, it would be a rather dumb idea.

That's what Google is for.

A good explaination on how to use eix-remote can be found here [1] and
as usual in the man pages.

Following the above, I see that the way ti search for remote (not
locally installed overlays) is to use the -R option.
From eix (app-portage/eix-0.28.5) man page:

-R, --remote
Uses the value of EIX_REMOTE1 as cache file name.  Use this option if
you want to see what eix-remote produced.  You  can  make this option
the default by setting REMOTE_DEFAULT=1.

So in /etc/eixrc/00-eixrc I have set
KEEP_VIRTUALS=true
REMOTE_DEFAULT=1

and now when doing a search I get results from all layman overlays
(either installed or not).

I am not sure whether the KEEP_VIRTUALS setting is needed though,
because the man page is *not* clear to me. Besides, in the bugs section
of the man page, it says:

The previous default KEEP_VIRTUALS=true used to confuse people. However,
with the new default, nobody will find out that this feature exists.  :(

With the current default setting of separate databases for the
local eix cache (normally /var/cache/eix/portage.eix) and
for the remote eix cache (/var/cache/eix/remote.eix),
KEEP_VIRTUALS=true makes no sense:

The purpose of KEEP_VIRTUALS=true was to update the local
cache data without changing the remote data with eix-update
(if both are in the same file).

However, especially if you set REMOTE_DEFAULT you should call
eix-remote add1
after every eix-sync so that your local eix cache is
copied into the remote eix cache
(see the manpage how to do this automatically with eix-sync).

Thanks, Martin.
So, if I understand correctly, I _don't_ need any settings, and I should
remove both KEEP_VIRTUALS and REMOTE_DEFAULT, and just use the -R option
when I want to search the remote cache and no option for searching the
local (installed) overlays and portage, is that correct?

You don't need KEEP_VIRTUALS.
Whether you prefer REMOTE_DEFAULT or not is up to you.

This has nothing to do with the necessity to call "eix-remote add"
after eix-sync: Otherwise your local portage tree will not get
"pushed" to the remote database /var/cache/eix/remote.eix

If you do not use REMOTE_DEFAULT, it is only less likely
that you will notice this since you will then see the outdated
local data only if you use -R  ;)

Martin, I appreciate your help, but I am still confused about the whole
<eix> thing.
My goal is to be able to query both local and remote data with one
command. To this end, what should the simplest configuration settings
be, and in relation to those settings, what would the sequence of
commands be for updating and then querying?

With eix-0.29.0 which just entered the tree, eix-sync will
by default do this for you, so you usually do not need to
care about.

Either you use eix -R ... (or eix -Z ...) or, alternatively,
you set REMOTE_DEFAULT=1 (or -2) to avoid typing -R/-Z.
(You have to type -R/-Z then if you want *only* a local query).

> what would the sequence of commands be for updating

With >=eix-0.29.0, if you use eix-sync, this will completely
care about updating the local data.

If you call eix-update manually (e.g. after changing some
local overlay manually) you should call afterwards
eix-remote add1 (and/or eix-remote add2, depending on whether
you use -R or -Z, i.e. depending which remote data you use).

For updating the remote data you just use as usual
eix-remote update1 (and/or eix-remote update2),

If you want to do the latter automatically with every eix-sync,
put e.g. the following lines into your /etc/eix-sync.conf:

@StatusInfo Downloading remote1
@eix-remote fetch1

(Of course, you can replace 1 by 2 and/or add corresponding
lines for 2 to fetch the alternative remote data).

(In /etc/eix-sync.conf it suffices to call "eix-remote fetch"
because the "eix-remote add" is called automatically
after the call of eix-update).

I have eix-0.29.0

So in /etc/eix-sync.conf I've set the following 2 lines
@StatusInfo Downloading remote1
@eix-remote fetch1

and the following 1 line in /etc/eixrc/00-eixrc
REMOTE_DEFAULT=1

(Thanks for your patience Martin)
