Any way to workaround interpolation of values in linked messages (or plants to support it)?

[rbsummers]

Hi!,

I have the following use case: i receive some abstract codes from my backend and each one has a specific message attached, so I wanted to do this:

// messages...
"items": {
  "code_1": "message for item with code code_1",
  //...
  "code_N" "message for item with code code_N"
}

// ...then translate
t(`items.${item.code}`)

My problem now is that some of these messages are going to be vastly different, while others might be very similar with the exception of some numbers, so I wanted to have the possibility of reusing an existing message via the linked messages / @: syntax and also interpolating at the same time. The desired scenario would be something similar to:

// messages...
"items": {
  "common_message": "Common message with {interpolated} value"
  "code_1": "message for item with code code_1",
  //...
  "code_42": "@:{'common_message`}{ interpolated = 'foo'}" // This syntax is made up and unsupported, I know
  // ...
  "code_N" "message for item with code code_N"
}

// ...then translate, but without sending params here!!
// These all should result in the same: "Common message with foo value"
t(`items.${item.code}`) // When item.code === 'code_42'
t('items.code_42')
// Using common + params should be equivalent too
t('items.common_message', { interpolated: 'foo' })

I don't want to pass the interpolated value when calling t, that is a dealbreaker for me as I will have to make a second config map where I store if each code uses the custom message or the common message and the value to interpolate.

I know there is no such syntax to support this using the @: notation, and I also tried to do it using message functions, but seems like the linked helper cannot pass parameters so the interpolation "slot" results empty:

"items": {
  "code_42": ({ linked }) => linked('items.common_message', { interpolated: 'foo' }) // This doesn't work either, produces "Common message with  value"
}

Does anyone have any idea how to do this (if possible?). Thanks!
