I guess none of us have problem of too much spare time :), so it took me
a while before I looked at neard.

With newer Gcc, neard did not even compile (which I am fixing now). I
set up a fork:
https://github.com/krzk/neard
However I can give early disclaimer - playing with GLib userspace code
is not something I am in long term interested. If this was written in
Rust, would be different story. :)

I also configured basic CI (or rather continuous building):
https://github.com/krzk/neard/actions/runs/1014641944

However I still do not have proper testing setup. No hardware. Would be
nice if Samsung. ST, NXP or Intel could spare some development board
with the NFC chip supported by kernel. Till then, I will try the NFC
simulator and virtual NCI drivers.

My next plan for neard is to extend the CI. There is no way I (or anyone
else I believe) can keep good quality of releases without automated
checks. I'll add some more distros, clang and later many some linters or
cppcheck.


Best regards,
