that is not directly possible. You can use the shell export mode together with
the field separator to build a list of tuples safe for processing, printf the
intermediate fields and finally use the array mode to build a proper list:
-- 8< --
eval $(ubus call network.interface dump | \
jsonfilter -F ': ' -e 'tuples=@.interface[@.up=true]["interface","uptime"]')
for tuple in $tuples; do
printf '{ "%s": %d }\n' "${tuple%:*}" "${tuple#*:}"
done | jsonfilter -a -e @
-- >8 --
Will result in something like the output below:
[ { "lan": 4409874 }, { "loopback": 4409873 }, { "modem": 803939 }, { "wan":
4040845 }, { "wan6": 2681477 } ]
Returning subsets of objects is not directly supported unfortunately but I'll
think about how to add something like this if I find the time.
