thanks for pointing this to me Charles.
no surprise, I've completely missed it!

read/write vars and instant commands are still the weak point, since this
effort was spawned from the dummy-ups effort...
I've also created another tracker for that part:
https://github.com/networkupstools/nut/issues/94

The way I see it, there are several use cases that overlap a bit:

   * clients development
   * QA regression testing (whole NUT framework)
(as in Ubuntu), currently use the default static device from dummy-ups,we
could there also imagine
   * device non regression testing
 by testing such outputs

indeed.

that's also what I'm thinking, with github tasks 3 and 4:

   -  Create a dedicated repository and website (
   http://devdumps.networkupstools.org)?
   -  Create a better page, or set of pages, to document / search / submit
   dumps ( @zykh <https://github.com/zykh>, would you be able to help?)

a dedicated website with some JS filtering / searching, as in the HCL,
could probably do it (hem, I'm unsure that it can scale however).
maybe some DB with pre compilation would be needed (manifest, indexing,
...).
but that's a bigger project.

a tool would also be needed to drive collecting data on the user's system,
à la "nut-recorder"

that may be an addressable point the nut-scanner Gen2 and weak deps:

sure ;)
in my defense, it goes back around the time I disappeared...
iirc, I only announced it on the mailing list (not sure which one however)

yup, started to track and share the effort, and finally dump things that my
little brain was holding for far too long...

cheers,
Arno
