I saw this too and was confused. For example if I'm trying to extract some disk details:
$ nvme list -o json | gron -v
panic: runtime error: index out of range [0] with length 0
goroutine 1 [running]:
main.gronValues({0xc000126070?, 0xc00012a010?}, {0xc000142170?, 0x7555d8?}, 0x1?)
github.com/tomnomnom/gron/main.go:411 +0x27f
main.main()
github.com/tomnomnom/gron/main.go:178 +0x6bc
The solution is to run gron twice in a row:
$ nvme list -o json | gron | gron -v
/dev/nvme0n1
0
0
1
0
Non-Volatile memory controller: Toshiba Corporation NVMe SSD Controller
1
0
/dev/nvme1n1
1
0
1
0
Non-Volatile memory controller: Toshiba Corporation NVMe SSD Controller
1
0
I think this was probably missed because in practice you'd never use gron by itself, it's meant to be combined with grep, so you'd do something like:
nvme list -o json | gron | grep SerialNumber | gron --values
This is alluded to in the comments:
Lines 401 to 404 in badf401
but not in the docs and it threw me off too. Maybe it can be explained with an example, or mentioning "Print just the values of gron-format assignments"?
And also it would be better not to panic at all. If the input format is wrong maybe that can become an error message explaining that the format is wrong.
