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() }

/**
 * Define clean up rules for the project.
 * See https://www.jetbrains.com/help/teamcity/teamcity-data-clean-up.html#Clean-up+Rules
 *
 * @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.

Ama şimdi bunu sıfırdan yazdığınızı hayal edin.

Bir noktada fonksiyon tanımını yazmaya başlamış olacaktınız, parametreler hazır...

Ama sonra "ilk harfi büyük harfe çeviren method"u çağırmanız gerekiyor.

`upper` mıydı? `uppercase` miydi? `first_uppercase`? `capitalize`?

Sonra eski programcı dostuyla denersiniz: editör autocomplete.

У певний момент ви розпочали б визначення функції, у вас були б готові параметри...

Але тоді вам потрібно викликати «той метод, який перетворює першу літеру у верхній регістр».

Це буде `upper`? Чи `uppercase`? `first_uppercase`? `capitalize`?

Тоді ви спробуєте давнього друга програміста — автозаповнення редактора коду.

        val percentEncoded = Buffer()
        for (i in 0 until utf8.size) {
          percentEncoded
            .writeUtf8("%")
            .writeUtf8(ByteString.of(utf8[i]).hex().uppercase())
        }
        return percentEncoded.readUtf8()
      }
    },

    /** URLs that contain this character in this component are invalid.  */
    FORBIDDEN,

          } else {
            evictToRecoverBytes(dynamicTableByteCount - maxDynamicTableByteCount)
          }
        }
      }
    }

  /**
   * An HTTP/2 response cannot contain uppercase header characters and must be treated as
   * malformed.
   */
  @Throws(IOException::class)
  fun checkLowercase(name: ByteString): ByteString {
    for (i in 0 until name.size) {

### 編輯它 { #edit-it }

這是一個非常簡單的程式。

但現在想像你正從零開始寫它。

在某個時間點你會開始定義函式，參數都準備好了...

接著你需要呼叫「那個把第一個字母轉大寫的方法」。

是 `upper`？還是 `uppercase`？`first_uppercase`？`capitalize`？

然後你試著用老牌程式設計師的好朋友——編輯器自動完成。

你輸入函式的第一個參數 `first_name`，接著打一個點（`.`），然後按下 `Ctrl+Space` 觸發自動完成。

但很遺憾，你什麼有用的也沒得到：
