What is a better way than `val port = property.getProperty("notification.port").orEmpty().let { if (it.isNotBlank()) it else "7100"}` ? Is there something like ``val port = firstContent(property.getProperty("notification.port"), "7100")` ?

Not sure what is property, but perhaps
`property.getProperty("notification.port")?.ifBlank { null } ?: "7100"` ?

thx. `getProperty` is a Java function which returns a `String?`.   I was looking for something like `String?.isNotNullOrBlankOrElse(def: String): String` (obviously with a better name).

with `fun String?.contentOrElse(def: String) = if (isNullOrBlank()) def else this`  I could write `val port = property.getProperty("notification.port").contentOrElse("7100")` . But such a function does not exists in the Kotlin stdlib, does it?

Maybe `property.getProperty("notification.port")?.takeIf { it.isNotBlank() } ?: "7100"` ?

I like that better than the `ifBlank { null }` approach, thx.

Could do function ref too: `?.takeIf(String::isNotBlank)`

might also throw in a `?.toIntOrNull()` call in there

yes to `?.takeIf(String::IsNotBlank)`.  This looks pretty readable and this `takeIf` approach is more general than my `contentOrElse` because I could do e.g. `?.takeIf { it.length &gt; 3 } ?: "longEnough"`

<@U345RGQ49>: yes is this case, but I have a dozen or so in my  code (host, path, query, ...) and most are actually `String` and not `Int`

&gt; most are actually `String` and not `Int`
hi, my name is javascript, and these are the same thing

welcome, javascript!  Once you grow up you will hopefully learn from and correct your life choices!
