Get YAML key which contains dot.

[artemklevtsov]

Hi,

How can I get value from the field which name contains a dot?

to reproduce:

# data.yaml

k1.k2: value

# test.blobl

root.keys = file("./data.yaml").parse_yaml().keys()
root."v0" = file("./data.yaml").parse_yaml()."k1.k2" # works but I need dynamic variable
root."v1" = file("./data.yaml").parse_yaml().get("k1.k2")
root."v2" = file("./data.yaml").parse_yaml().get("k1").get("k2")

test:

❯ echo | benthos blobl --file test.blobl
{"keys":["k1.k2"],"v0":"value","v1":null,"v2":null}

Hey @artemklevtsov, you can try root.src = file("./data.yaml").parse_yaml().get("k1~1k2"). The syntax is documented here: https://docs.redpanda.com/redpanda-connect/configuration/field_paths/

The characters ~ (%x7E) and . (%x2E) have special meaning in Redpanda Connect paths. Therefore ~ needs to be encoded as ~0 and . needs to be encoded as ~1 when these characters appear within a key.

Alternatively, this should also work: root.src = file("./data.yaml").parse_yaml()."k1.k2"

thanks for the quick and clear answer.
