or any other case variation (uppercase, first letter in uppercase, etc), your function will see the parameter `short` with a `bool` value of `True`. Otherwise as `False`.

В какой-то момент вы бы начали определение функции, у вас были бы готовы параметры...

Но затем нужно вызвать «тот метод, который делает первую букву заглавной».

Это был `upper`? Или `uppercase`? `first_uppercase`? `capitalize`?

Тогда вы пробуете старого друга программиста — автозавершение редактора кода.

Irgendwann sind die Funktions-Parameter fertig, Sie starten mit der Definition des Körpers ...

Aber dann müssen Sie „diese Methode aufrufen, die den ersten Buchstaben in Großbuchstaben umwandelt“.

War es `upper`? War es `uppercase`? `first_uppercase`? `capitalize`?

Dann versuchen Sie es mit dem langjährigen Freund des Programmierers, der Editor-Autovervollständigung.

    }
}

fun String.toCapitalized() = this.replaceFirstChar { if (it.isLowerCase()) it.titlecase(Locale.getDefault()) else it.toString() }

fun String.toCamelCase() = lowercase().replace(Regex("_[a-z]")) { it.value[1].uppercase() }

 *
 * @param historyDays days number of days to store build history .

At some point you would have started the definition of the function, you had the parameters ready...

But then you have to call "that method that converts the first letter to upper case".

Was it `upper`? Was it `uppercase`? `first_uppercase`? `capitalize`?

Then, you try with the old programmer's friend, editor autocompletion.
