basically I need some details on how such names are encoded in d1 and d2 properties of @Metadata

[gildor]

There is an introduction to @Metadata structure from @Eugenio

[udalov]

We're working on a library to give access to that data, it's coming shortly, see https://youtrack.jetbrains.com/issue/KT-23198

[dstarcev]

@udalov will kotlin reflection be broken if names of the properties defined in the primary constructor are different from the according backing fields? e.g. as the result of obfuscation

[Eugenio]

@dstarcev yep!

[Eugenio]

@udalov will it also work at compile time (like with kapt), or only runtime?

[udalov]

@dstarcev can’t say for sure, but yeah, probably

[udalov]

@Eugenio both. It takes kotlin.Metadata’s content (ints, arrays of strings, etc) as an input

[dstarcev]

@Eugenio can I use https://github.com/Takhion/kotlin-metadata to parse kotlin.Metadata contents?

[gildor]

Yes

[Eugenio]

@dstarcev yes, in a few days I'll release v2 which will make it a lot easier (and documented 😅)

[Eugenio]

This not only does the parsing of the metadata, but uses the Java Annotation Processing APIs to derive type information, kinda like Kotlin reflection, but at compile time

[Eugenio]

It's still lower level though

[Eugenio]

Because you don't necesaarily have access to full types, the rules are slightly different

[dstarcev]

@Eugenio how do I do it with the current version? I have values of kotlin.Metadata properties as an input

[dstarcev]

If I am not mistaken, I need to get an instance of me.eugeniomarletti.kotlin.metadata.KotlinClassMetadata
