It looks like libxo does the output in structured format, but what about input? (For chaining commands together with pipes). Did the FreeBsd porting work[1] implement the input side with libxo, independently of libxo, or not at all?

(Not to diminish libxo --it looks pretty cool, and I didn't know about it before-- just curious.)

On the input side, FreeBSD prefers libucl https://github.com/vstakhov/libucl

I don't think input meant configuration file syntax here, but actual

    echo $somejson-jobspec | ifconfig

instead of

    ifconfig em0 inet 192.02.1/24 alias
