add output file for ffdon

[T0biii]

according to:
https://gist.github.com/herbetom/f8eae6fde7a00c59f4333b49c189c784
we can add more outputs + filter the output

config is untested

Looks about right? :D

[herbetom]

Not quite sure if it's right. From what i could tell filtering works on a site base and what you've listed seem to me to be domains.
So you might need to move the ffdon domains in their own site and then filter for that single ffdon site.

https://github.com/FreifunkBremen/yanic/blob/c19c1aed1b237480895e50f0bd50e6ff3758fadd/config_example.toml#L23-L29

Looks better. I don't know wheter domains can appear multiple times. But it's probably worth an attempt.

I took the liberty to push a small commit applying the changes that Black complained about in CI so it is green.
Looks good, I'll try deploying it.

[DasSkelett]

Deployed, but the JSON is empty:
https://map.ffmuc.net/data/meshviewer-ffdon.json
https://gw04.ext.ffmuc.net/meshviewer-ffdon.json

{"timestamp":"2024-02-11T15:07:29+0100","nodes":[],"links":[]}

So maybe the same domain in multiple sites does indeed not work. I might check the yanic code later to confirm this (or see whether it could be changed)

[DasSkelett]

Turns out yanic uses the site_code the node itself returns in the respondd data for filtering. Which kind of makes sense thinking about it.

(nodeinfo.System.SiteCode is basically only written to from the respondd returned JSON)
I'm not really seeing a good way to do this in yanic right now.

Mabye we can adjust site_code in the gluon domain configs for the ffdon domains, but no idea what other site effects this would have (@grische ?).

[T0biii]

maybe we can set the Paramter to use the Domaincode instead?

[nodes.output.meshviewer-ffrgb.filter]  
sites = ["ffdon"]  
domain_as_site = true
