Posted: Fri Mar 04, 2016 4:28 pm Post subject: app-portage/eix ... usage, examples, etc

This thread is intended as a dumping ground for app-portage/eix usage, examples, tips ... as per the request in Help!! Good blog/guide to Gentoo tools? eix, qlist, etc.??

List all installed packages that are ~arch keyworded

Code:

# eix --only-names --installed-unstable

List all packages installed from the 'foo' overlay

Code:

# eix --only-names --installed-from-overlay foo

List all packages installed with USE="ssl"

Code:

# eix --only-names --installed-with-use ssl

List the currently installed version of 'firefox'

Code:

# eix --format '<installedversions:NAMEVERSION>' firefox

Show a 'compact' listing for the package 'zsh' (-e, 'exact' is used so that the pattern doesn't match other packages, like 'app-shells/zsh-completions', that includes the string 'zsh')

Code:

# eix -ec zsh

Show all installed packages

Code:

# EIX_LIMIT_COMPACT=0 eix -Ic --only-names

Show all installed packages, ordered by, and including, install date

Code:

# eix-installed-after -de0

Have 'eix-sync' also 'sync' the overlays defined in repos-conf/* (so, layman installed overlays, etc) and so all repos are updated. This means you need only call 'eix-sync' rather than 'emerge --sync && layman -s', etc.

/etc/eix-sync.conf:

You can also have it run 'egencache' and update 'metadata' for these overlays ...

/etc/eix-sync.conf:

@StatusInfo 'Updating metadata for foo overlay'
@egencache --repo=foo-overlay --update --update-use-local-desc

Note that 'eix-sync' will run 'eix-update' and 'eix-diff' along with sync'ing the repos ... so the eix database is updated, and a 'diff' is provided of the tree.

Find all 'bin' packages (this was initially posted in Finding binary packages?)

Code:

# EIX_LIMIT=0 eix */*-bin

You could similarly use a wildcard to match other partial strings, ie app-vim/*-syntax, or to list all packages in a category, ie 'www-client/*', or 'app-vim/*'.

Similar to the above 'installed-with-use' example there is also 'installed-without-use'. This can be used to find all packages with a useflag disabled, eg:

Code:

# eix --only-names --installed-without-use gnutls

Query portage variables, like PORTDIR, PORTDIR_OVERLAY, DISTDIR, ACCEPT_KEYWORDS, etc. Somewhat easier to remember than 'portageq get_repo_path $(portageq envvar EROOT) gentoo', or running 'emerge --info' for, say, getting USE.

Show PORTDIR

Code:

# eix --print PORTDIR

Show useflags

Code:

# eix --print USE

List all locations/paths for repo's

Code:

# for i in PORTDIR{,_OVERLAY} ; do eix --print $i ; done

I was going to post a question about how to do this! Many thanks, khay! And many thanks for your tireless work here.

Good list!

The eix-installed-after script might be helpful, too, like doing

Code:

eix-installed-after -b sys-devel/gcc-5.3.0

which actually shows everything that was installed *before* gcc-5.3.0.

I already posted this on another place, but the main purpose of the eix-installed-after script is to serve as an example: It is relatively exhaustively commented so that hopefully it is useful for many who want to use eix for a non-trivial task.

Yamakuzure ... hmmm, I must be living in some alternate time dimension ;)

Code:

Mon Mar 7 14:05:30 2016 >>> media-libs/harfbuzz-1.1.3

... so, that is not "before", however, stranger still, if I provide category/package (sans 'version') then, I get something altogether different ... but still not "before".

Code:

# eix-installed-after -b sys-devel/gcc | tail -n 1

Unless I misunderstand the terms 'before', and 'after', then I'm not sure what 'eix-installed-after' is doing. Also, if the script can output both 'before' and 'after' it should be called 'eix-installed-order', or in my case 'eix-installed-timewarp' ;) That is one of the frustrating things about eix, its a really useful tool but the way it works, or is expected to work, often leaves me with more questions than answers.

Yes, I didn't realize: Either you must specify option -v in addition or use the syntax

Code:

eix-installed-after -b sys-devel/gcc:5.3

Quote:

Maybe, but this would hide the "default" mode of output (which I considered the most useful one, because it sometimes happens that you installed a "bad" package causing possible breakage for subsequently installed packages - so you can easily list them).

You get your "eix-installed-ordered" behaviour with option -f.

What the script actually does is simply to output all packages ordered according to install date, but to start (or with option -b: stop) this list only when the output matches the argument.
With other options (like -l -e or -F) you can check for the timestamp instead of the output text (hence avoiding the "problem" that the argument must match the output format).

You are welcome to submit patches (or if you cannot do it suggestions for improvement).
(And in contrast to some systemd developers, I really mean this - there is really not much feedback to eix.)

I don't see why 'installed-order' hides anything, in fact, its more explanatory. Also, you could still default to 'after'.

I don't doubt your sincerity ITR, the problem is I wouldn't know where to start, I find a lot of the man page completely opaque, and difficult to get to grips with, and I'm generally fairly good with such things. So, I've never really got a sufficient grasp so as to be in the position of looking and specific things which might be improved ... a veritable chicken & egg problem. That is in no way a discredit to the work you put in, its just as I see it, eix just seems over-engineered, and over-burdened in terms of syntax. That's partly the result of the complexity, or over-complexity, of portage, but it does make it less of a go-to tool. I'd imagine the great majority of people who use it are simply using as a replacement for 'emerge --search'. Anyhow, here is probably not the best place for such a discussion, this is a tips and examples thread, so probably enough said.

I had previously posted only from my memory - I had no gentoo machine accessible. Now I checked, and it seems what I posted was correct with 2 inaccuracies:
1. The slot sys-devel/gcc:5.3 does not exist. It should be e.g. sys-devel/gcc:5
2. The output format plays no role (the script is more clever than I remembered); when you want to specify the format sys-devel/gcc-5.3.0 you can use the option -V

Maybe there is a misunderstanding what is meant by the "emerge time" of a package: It means the (latest) build time of the installed package (stored in BUILD_TIME in /var/db/pkg).
(If you should have set the eix variables USE_BUILD_TIME to false, it is the mtime-timestamp of the corresponding /var/db/pkg directory - which is usually roughly the same).
In your case, you have perhaps emerged wpa_supplicant later on again, so that the above time stored in emerge.log has become irrelevant.
(There might also be other reasons, e.g. if you installed from a prebuilt binary package.)

Quote:

I'd imagine the great majority of people who use it are simply using as a replacement for 'emerge --search'.

Or to check which versions are available/masked/installed. I also use it for this mainly. Only in very rare cases, some script can really profit from the other features. But these cases happen occasionally.

About renaming eix-installed-after: Maybe you are right that the name was chosen unfortunate. However, I am hesitating to rename it now when perhaps some users have scripts referring to that name. And using symlinks (two names) would only increase confusion.

Greetings khayyam,

And, thanks again for this thread... VERY helpful!
But, now I have a question regarding eix and slotted installs (e.g. python):
When I run the following command:

Code:

NAMEVERSION="<category>/<name>,<version>" eix '-I*' --format '<installedversions:NAMEVERSION>,<licenses>\n'

it looks good until I get to the following:

Code:

...
dev-lang/perl,5.24.1-r2,|| ( Artistic GPL-1+ )
dev-lang/python,2.7.12dev-lang/python,3.4.5dev-lang/python,3.5.3,PSF-2
dev-lang/python-exec,2.4.4,BSD-2
dev-libs/boost,1.62.0-r1,Boost-1.0
...

Is there any way to break out the slotteds each to their own line?

TIA for your assistance.

Not sure what you mean. Perhaps

Code:

NAMEVERSION='<category>/<name>,<version>,<licenses>\n' eix '-I*' --format '<installedversions:NAMEVERSION>'

Be aware, however, that eix stores only one license per package (that of the latest available version), so the information will not be correct if different slots have different licenses.
Simliar problem happens with other metadata too, e.g. descriptions.

@mv: Thanks for the reply.

What I mean is the one line above with dev-lang/python writing all 3 slotted versions to one line... e.g.:

Code:

dev-lang/python,2.7.12dev-lang/python,3.4.5dev-lang/python,3.5.3,PSF-2

And, I already tried your suggestion and it comes out like this:

Code:

dev-lang/python,2.7.12,PSF-2dev-lang/python,3.4.5,PSF-2dev-lang/python,3.5.3,PSF-2

which is better, but it still puts all slotted versions on one line.

So, is there a way to put the slotted installs each on their own line?

TIA.

Use single-quotes, or the shell will interpret backslashes (eg to avoid \$expansion), resulting in a plain 'n'.
Bash allows eg: $'\t' or $'\n' escapes as well (should the underlying tool not interpret standard C escape sequences.)

It shouldn't. As SteveL already pointed out, perhaps you have used the wrong quotation marks when copying my suggestion.

There must be some handling for that issue as it seems to work with either " or ':

Some Gentoo developers keep breaking the eix package because they have a grudge against its author. Of course, it's us users getting the shaft every time they pull an infantile stunt like this. The solution is to use the un-"enhanced" eix ebuild from the mv overlay.
