06/20/2023, 7:04 AMfor some CLI apps I found it easier to pass in a JSON5 file as the only arg (or default to an environment variable) and use Kotlinx Serialization json5k to decode it to a MyCliAppArgs class
I had a vague idea a while ago for using creating a Kotlinx Serialization format for decoding CLI args… https://kotlinlang.slack.com/archives/C7A1U5PTM/p1668606897420759
