Indexed properties as environment variables?

[edeandrea]

Looking at https://quarkus.io/guides/config-reference#indexed-properties, how would I express the following

my.indexed.collection[0].name=dog
my.indexed.collection[1].name=cat
my.indexed.collection[2].name=turtle

As environment variables?

MY_INDEXED_COLLECTION_0_NAME=dog
MY_INDEXED_COLLECTION_1_NAME=cat
MY_INDEXED_COLLECTION_2_NAME=turtle

Does not seem to work.

Have you tried something like:

MY_INDEXED_COLLECTION_0__NAME=dog
MY_INDEXED_COLLECTION_1__NAME=cat
MY_INDEXED_COLLECTION_2__NAME=turtle

IIRC special characters are replaced with a _. But it might not work for indexes.

/cc @radcortez who will know more about this :).

For environment variables in the Quarkus docs we refer to upstreams:
https://quarkus.io/guides/config-reference#environment-variables

Which link here:
https://smallrye.io/smallrye-config/latest/config/environment-variables/

We can of course improve all the documentation. We recently rewrote the SmallRye Config docs, but the main webpage is still linking to the old docs (Quarkus docs already link to the right one).

@edeandrea what do you think?

Thanks @radcortez.

I think the docs look good. I think what was misleading was

replace each character that is neither alphanumeric nor _ with _

which makes sense that MY_INDEXED_COLLECTION_0__NAME=dog works, since there is a ] followed by a ., which when both are replaced with _, you get two __ in a row.

Just a Jedi mind trick :)

The format looks a bit weird, but I ended up going with that format to keep it consistent with everything else.

[edeandrea]

I don't think there's anything else we need to do here.

I tried

MY_INDEXED_COLLECTION__0__NAME=dog
MY_INDEXED_COLLECTION__1__NAME=cat
MY_INDEXED_COLLECTION__2__NAME=turtle

and that did not work. I will try what you mentioned.
