Chaining refined string operation #1080
Description
Context
Hi, I would like to use REFINED to validate some custom input string I have. For some of the string, I would like to chain existing refined string operation as start_with and uuid.
Exemple
The input string I have looks like random_VALID_UUID. At the moment I write a custom refined type as:
final case class PrefixedUUID[S](prefix: S)
object PrefixedUUID {
implicit def prefixedUUIDValidate[S <: String](
implicit
prefix: Witness.Aux[S]
): Validate.Plain[String, PrefixedUUID[S]] = {
Validate.fromPartial(
s => {
if (s.startsWith(prefix.value)) {
val uuid: String = s.stripPrefix(prefix.value)
require(java.util.UUID.fromString(uuid).toString == uuid.toLowerCase)
} else {
throw new Exception("Not a valid UUID")
}
},
s"""PrefixedUUID("${prefix.value}")""",
PrefixedUUID(prefix.value)
)
}
}
Is it the best approach to do it? Can I do it in a more generic way (chaining native refined operation)? If not, maybe can you lead me on how I can contribute a generic way to do it for the core refined library, if you are interested?
Thanks,
