Have you tried to use a Lens
as second parameter?
I guess it could look similar to Lens(myMeta) { _ -> LocalTime.now() }

Yes, but I might have done it wrong. I struggled with the constructor, because I couldn't create a Meta
object.
I looked at the official defaulted
, which did:
defaulted(name, Lens(Meta(false, location, paramMeta, name, description)) { default }, description)
, but I dont have access to location
and paramMeta
when I want to create myMeta
.
Query.instant().defaulted("start", Lens(meta = ???, { _ -> Instant.now() }))
The source code isn't obvious either, so I have no clue what location and meta are, and if I can construct them myself easily, or what data should even go into them. If you have any advice, I would appreciate it.

It seems the location and paramMeta come from the Query
object, so something like this?
Query.instant()
.defaulted(
"start",
Lens(
meta =
Meta(
required = false,
location = Query.location,
paramMeta = ParamMeta.StringParam,
name = "start",
description = "My description of start"),
{ _ -> Instant.now() }))
Quite verbose compared to e.g. a Query.instant().defaultFactory("start", { Instant.now() })
from http4k.
I've made the defaulted mechanism take a LensExtractor (Request) -> T
and made it a fun interface, so you can now do: ```
Query.int().defaulted("foo", { 123 })
Will be out in the next version
