Mapping with fixed values

[fhalde]

Is it possible to have fixed values in a Mapping? We have a consumer properties field which is a free-form map, however some values are not supposed to be amendable e.g. monitoring port

Are you in control of the configuration schema? If so, try separating them into different properties. For example:

fixed port: Int = 5050

properties: Mapping<String, String|Int>

If, say, you aren't in control of the schema and need this to turn into a flat mapping, you can merge this before providing it to your target system.

For example, here, port and extraProperties as hidden, so that they don't show up in your output. And, you have fixed properties which is computed from the other two properties, which is non-hidden and shows up in the final output.

hidden const port: Int = 5050

hidden extraProperties: Mapping<String, String|Int>

fixed properties: Mapping<String, String|Int> = (extraProperties) {
  ["port"] = port
}
