Writing an Open API Parser
summary
Builds a Kotlin OpenAPI parser that reads YAML via kaml and kotlinx.serialization, resolves $ref recursively, and generates a live Jetpack Compose UI mapping each path to cards and buttons. Traverses the spec multiple times—parse, resolve references, discover variable fields, render input dialogs, then substitute values and execute requests with OkHttp on Dispatchers.IO. Prototype uses Retrofit wiring, handles markdown descriptions, runs and issues real requests but omits authentication and uses a naive traversal that needs optimization.
