That's great! There's also default values for that, thanks!

By the way, are there any plans to use KSP to somehow avoid using reflection at runtime?

Any suggestions or thoughts on how to support a config value with the signature

Map<String, Any>

? The error trying to use with the following sample values with a hocon source results in

Unable to locate a decoder for class kotlin.Any

props {
  intVal = 1
  stringVal = "a"
}

I'm using it to populate a

java.util.Properties

object. I don't see a Decoder available out of the box, so before I explore a custom Decoder thought I'd check in case I'm missing something simple. Thanks!

Hello, is it possible to add prefix for config? Right now using env variable source and want them to all start with prefix e.g.

data class ExampleConfig(val test: Boolean)

EXAMPLE_TEST=true

so you want to strip a prefix from env vars? So like FOO_BAR=true overrides bar/BAR?

Nope want to add a prefix, as it is now when loading that class would expect

TEST=true

but want it so when i load the config i can pass prefix like "EXAMPLE" and it would expect

"EXAMPLE_TEST=true"

I think we're saying the same thing. You have a field called foo and you want the env var to be WHATEVER_FOO

Ah yeah, misunderstood 😛

ok cool

do you have a config file ?

Nope doing it 100% through environment variables

are you using the env property source ?

Yep

ConfigLoaderBuilder.default()
            .addPropertySource(EnvironmentVariablesPropertySource(useUnderscoresAsSeparator = true, allowUppercaseNames = true))
            .build()
            .loadConfigOrThrow<SomeConfig>()

Let me add that feature

Thanks!

you on latest ver?

Latest release (2.6.4) although I'm fine with updating to snapshot

yeah 2.6.5 is being released atm

Appreciate it blob smile

course

ok 2.6.5 is released but it can take 15 minutes to show up in maven

there's a new parameter on that env property source of prefix, just specify the prefix you want to be stripped

Beautiful, just gave it a try and it works good, thanks again!

awesome

@sam, Can I have a config like

data class AppConfigs(val fooSet: Set<Foo> = emptySet())

where

fooSet

might be empty?

Hi - is there a

ConfigLoaderBuilder

recipe that mimics the opinionated default loader behaviour of TypeSafe/Lightbend Config, including fallbacks and the various optional property overrides? https://github.com/lightbend/config/blob/main/README.md#standard-behavior

Also, does the builder cache the built configuration environment variables used somewhere? I've written some tests injecting environment vars, and they pass when run individually, but there are failures when run as a suite. If so, is there an approach (apart from the

ReloadableConfig

) that forces expiry of cached values?

I'm loving the

withReport

feature and its related decorators like the HashObfuscator...I don't see it documented yet though, so wondering if it's already documented somewhere, or if you're intentionally not documenting it yet for any reason? If not, lemmeno and I'd be willing to submit a PR for its documentation.

We should add the documentation yeah, I added that feature as we use it internally when deploying our microservices, and it's been in use for about a year, so it's fully stable.
