C pkg plugin to display orphaned packages

[zirias@]

From time to time, I need to check my machines for installed packages that aren't available in my repository any more, so I can remove them. This is possible with pkg query, pkg rquery and a little shell scripting, but each time I have to think again how to script this, and it really isn't efficient either.

So, having discovered pkg offers a plugin API, I quickly created a little and stupid plugin doing just this. Maybe someone finds it useful

pkg version -vRl'?'

     ?       The installed package does not appear in the index.  This could
             be due to an out of date index or a package taken from a PR that
             has not yet been committed.

     -l limchar, --like limchar
                 Display only the packages which status flag matches the one
                 specified by limchar.

From pkg-version(8).

I usually check my machines with pkg version -vRL=. This will show everything that needs to be updated or has been orphaned, i.e. everything that's not up to date.

Ah yes, outputs a bit more than I need, but that's also easily fixed in shell script, so I could drop the plugin again.
Anyways, nice experience to test out the plugin API

I might have a look at your plugin too when I have the time for it. Until quite recently I wasn't even aware there was a plugin option for pkg(8)

With regards to query and rquery, I do know you can make aliases for those. That's also a nice feature to play with, there are some interesting ones already defined:

# pkg alias

Nice indeed! But to find orphans this way, you have to do something like this

for p in `pkg query %n`; do pkg rquery %n $p >/dev/null || echo $p; done

so aliases wouldn't help here and it's very inefficient, spawning a pkg process for every installed package

Your approach with pkg version solves this nicely.
