Description

There's currently no way to default annotations to snake casing without having to manually specify each one. For example, given the following code:

case class Input(
  @query
  notSnakeCase: Int
)

This will produce an endpoint accepting query parameter of name notSnakeCase. Ideally, I’d like to be able to generically change all such occurrences to not_snake_case instead.

Something similar to the magnolia configuration:

implicit val configuration: AnnotationConfiguration = AnnotationConfiguration.default.withSnakeCaseMemberNames

From thread:

Research direction

Start by reviewing Tapir's endpoint input annotation handling and the linked community discussion about generic configuration. Define how an implicit configuration should affect annotated member names, including the snake-case example, and confirm the behavior with appropriate endpoint input coverage.
