Applied! I didn’t check whether OBS can actually load it, but I seeit’s installed under ‘lib/obs-plugins’, which is where the new searchpath expects to find it, so it should be fine.
Thanks,Ludo’.

Very nice! Thank you!
It won't load until obs updated to the commit with OBS_PLUGINS*_PATHvariables support [fn:1], but as you said it's future-proof and alreadyinstalls to the correct location.
There is another very similar patch, which adds another obs plugin. Youprobably already aware of it, but here is a link:http://issues.guix.gnu.org/45961.Accidentally, it has empty propagatedinputs and I'm not sure if it will apply to current master at all, but Ican update it if it's needed.

Ah ha! So on ‘master’, there’s the OBS_PLUGINS_DIRECTORY patch that youprovided earlier, which is why I wrote that the plugins should work.
Should we wait for the next OBS release instead of packaging anarbitrary commit?

Hi,
Thanks for merging my patch =) I am not insist on keeping [1], but I do think that is more cleaner solution.
With the upstream patch, Obs will be able to extend the list of plugin directories. We are going to add ~/.guix-profile/ to that list, which means Obs will have two different locations with partially different so files. It doesn't look clean to me.
In addition, [1] doesn't require to have OBS_PLUGINS_DIRECTORY variables. If there is no such, it will run with its defaults.
