[dave08]

@sam I'm trying to use env vars for setting configs in intellij's run configs, but for some reason hoplite isn't picking them up (the code is in the thread

[dave08]

data class Settings(
    val bucketName: String,
    val endpoint: String,
    val accessKey: String,
    val secretKey: String,
)

val config by lazy {
    ConfigLoaderBuilder.default()
        .addPropertySource(EnvironmentVariablesPropertySource(false, false))
        .build()
        .loadConfigOrThrow<Settings>()
}

[dave08]

Trying to use something like settings.bucketName for env var name...

[dave08]

But I get:

Caused by: com.sksamuel.hoplite.ConfigException: Error loading config because:

    - Could not instantiate 'com.lomdaat.plugins.Settings' because:

        - 'bucketName': Missing from config

        - 'endpoint': Missing from config

        - 'accessKey': Missing from config

        - 'secretKey': Missing from config

[dave08]

Is there any way of printing out what keys hoplite actually "sees"?

[dave08]

Oh... settings. shouldn't be there... which is pretty inconsistent with the yaml format, no?

[sam]

If you're on 2.0.x then you can add .report

[dave08]

.report ? Doesn't seem documented in the README?

[dave08]

Ok, but in a scratch file it doesn't seem to work... I'm trying to use System.setProperty(...,...) to provide the values in the scratch file, but it seems to crash with the previous error and .report() doesn't give me anything...

[sam]

Hmm maybe I didn't update docs for report on the latest 2.0

[sam]

ConfigLoaderBuilder.default().report...

[dave08]

I did that:

val config by lazy {
    ConfigLoaderBuilder.default().report()
        .addPropertySource(EnvironmentVariablesPropertySource(false, false))
        .build()
        .loadConfigOrThrow<Settings>()
}

[sam]

There you go

[sam]

If you want to use env you can override in the field d. That's in the docs

[dave08]

I got this:

[dave08]

But no report (maybe scratch files work different?)

[sam]

Hmm

[sam]

I'm on a plane so will have to look later 😂

[dave08]

I even rebuilt the code just in case it didn't pick up the change... do system properties expect settings.bucketName or just bucketName?

Oh... have a nice flight ✈️!

[sam]

There's special syntax for sys props

[sam]

It's in the readme

[sam]

-dconfig.override.foo or something

[dave08]

Ok, as long as the startup doesn't crash, the report gets printed on the scratch's side pane... doesn't help when debugging crashes, but maybe scratches aren't a typical use-case... also, overriding with system props in scratches doesn't seem to work, so I had to use a resource application-local.yaml file that doesn't get committed to git... but I guess now it works, thanks!
