【自分向けメモ】Goのfmtパッケージのフォーマット書式

More than 1 year has passed since last update.

Goのfmtパッケージを使用する際に下記のように使われている %v とかってなんやろとずっと思っていた(調べろよ)。

package main

import (
    "fmt"
    "os"
    "time"
)

func main() {
    fmt.Fprintf(os.Stdout, "Write with os.Stdout at %v", time.Now())
}
// => Write with os.Stdout at 2018-12-23 16:18:29.716124 +0900 JST m=+0.000328670
