printing of package versions available only from an overlay

[efferre79]

I would like to print a list of packages installed from a specific overlay. The list must include only the installed package versions coming from the specific overlay, the output should not contains all the versions installed from gentoo or other overlays.

If I use this command

eix --in-overlay REPO --format '<installedversions:NAMEVERSION>'

then all the versions are printed even if not present in the specified overlay REPO. So I thought of using the conditional formatting:

eix --in-overlay REPO --format '{overlaykey=REPO}<installedversions:NAMEVERSION>{}'

but it doesn't seem to work.

Try something like this

N='{overlayplainname=REPO}%{NAMEVERSION}{}' eix --in-overlay REPO --format '<installedversions:N>'

That helps but only if I specify a pattern, with an empty pattern I get no result.

I cannot reproduce this here. Maybe you have some nonstandard default options set for eix: Does omitting the --format (and its argument) output something if you do not specify a pattern? In any case, specifying -r (searching for an empty regular expression) should work.

If I omit --format I get the list of packages. But when using --format I get No matches found (even if I use -r). I am using version 0.36.7-r1, latest in portage.

Sorry, I cannot reproduce this.

The only thing I get is a list of 5 overlays:

N="{overlaynum=1}%{NAMEVERSION}{}" eix  --in-overlay REPO3  --format '<installedversions:N>'
[1] "REPO1" /path/to/repo1
[2] "REPO2" /path/to/repo2
[3] "REPO3" /path/to/repo3
[4] "REPO4" /path/to/repo4
[5] "REPO5" /path/to/repo5
No matches found

Oh, you did not see that I fixed a typo in my first reply.

good catch, now it works like a charm! Thanks for the help! I would suggest to add this example in the manual, I think it might be useful to other people

There are so many examples some people find useful, and the manpage is already more than long enough.
