in-line update using implicit type not working with YANG list

[sanooprajan]

I am trying to do a "set" operation using in-line update and implicit type using both --update-path and --update-value flags as below for a path that is a yang list not a leaf. But it fails.

gnmic set --update-path --update-value

however if i do the update with a value from JSON using both--update-file flag for the value and --update-path for the path, it works. Looks like it is not able to parse a list in command line. is this a bug ?

without logs it is impossible to tell
you can use prototext or protojson output format to see the raw values sent to the target

Also, what kind of error do you get back?

[sanooprajan]

is this something that you requested for ? Let me know if you need something else.

[hellt]

please format the code snippet with triple backticks

```
your output goes here
```

And I believe you're not providing the expected inline value, your path /interfaces/interface[name=et-0/0/4]/subinterfaces/subinterface[index=0]/ipv4/addresses/address[ip=11.11.11.1] points to a list element, not just a plain value.
you should consider using json/yaml file and put your interface config there.

To see how to use gnmic with openconfig paths you can check this resource.

@hellt It works if i use json, the problem is with in-line update. Are you saying with in-line update we cant have list values?

[hellt]

you often can, but you will have to provide the json string inline, and escape all the characters that would otherwise mean an element delimiter, for instance.

inline values are good for changing a single value (bool, str, int), but not great for json objects

[sanooprajan]

@hellt Is it possible to have an enhancement and extend it to list value update also ? I was using the templated way of config push like below.
gnmic set --request-file <template1> --request-file <template2> --request-vars <vars_file>
Can it take json object as well?
