Is that something internal which returns
ConfigValue[Secret[A]] by default?
I think the third-party libraries are all unassuming and return
ConfigValue[A].
Hey folks, quick question: if I'm fetching multiple parameters from SSM with ciris-aws-ssm, should I reuse the
Param I get from Blocker[F].flatMap(params[F]) as much as possible, or is it fine to split credential fetching over multiple functions each of which calls Blocker[F].flatMap(params[F])?
@Hjdskes You can reuse it. It's basically shown in the readme: https://github.com/ovotech/ciris-aws-ssm
Stack safety of
flatMap might be an issue...
hmm, there is
FlatMap[ConfigValue] already
I guess
final def eval[F[_], A](value: F[ConfigValue[A]])(implicit F: Effect[F]): ConfigValue[A] might be my workaround.
@kubukoz Yes,
flatMap cannot be expressed in a stack-safe manner, and also pure would not be what you expect, as discussed here: https://gitter.im/vlovgr/ciris?at=5dc6643b5eb2e813dbf0f3b0
There is no generic derivation, partly because there is no 'one way' to generically read a configuration.
There's also
ConfigValue.async if you really need something like Async[ConfigValue].
Here's what I had in mind https://gist.github.com/kubukoz/91ff72ee5764b6b42d4b38df2562d47b
I guess you also run into problems if you have two or more of the same type in your product, but want to read them differently.
two of the same type shouldn't be a problem for me, so I guess it's just one of the patterns
at the root type there will always be distinct types, but I see why it might not be true in the nested ones
have there been any attempts to integrate with cats-effect 3 milestones yet, @vlovgr ?
Biggest change with that proposal is
ConfigValue[+F[_], A], similar to fs2's Stream.
(didn't click yet, just judging by what the type param can get us)
Here are some links if you want to see the discussions from the cats-effect gitter channel:

Hey folks, is this a useful addition to ciris? Does it already exist but I've overlooked it?
https://github.com/dimitarg/ciris-propsfile/blob/master/src/main/scala/ciris/propsfile/package.scala
example usage at
Let me know if it doesn't exist and is useful and you'd like such a PR
I prefer to use env usually but had to switch a project to files because of security considerations, this little bit came out of that
Do you see this as something in core, or a separate module ?
Hi @vlovgr
the docs on the microsite at https://cir.is/ state ciris to be available for 3.0.0-RC3 but sbt is unable to fetch it.
Do you have the leisure to release ciris for 3.0.0-RC3?

@roland.manfrahs_gitlab Ciris v2.0.0-RC3 is now out with support for Scala 3.0.0-RC3. Sorry for the delay.
I have a value I need to encode differently based on some config. lets keep it simple
case class MyValue(value: String)
case class MyValueEncodingPrefix(value: String)is there a nice way of doing this with Ciris? ConfigValue seems to need an Async to load and Circe's Encoder isn't async.
@ShahOdin Is the value also loaded from configuration?
ConfigValue only describes how to load a configuration. Normally you would load the configuration first as a separate step, then use that configuration to do something else, e.g. encode a value. In that sense, ConfigValue and Encoder are separate.
