100% test coverage (that was easy :-))

fmtdate provides a date formatter and parser using the syntax of Microsoft Excel (TM).

Additionally it offers default conversions for date time and datetime.

Why?

Microsoft Excel (TM) has a well known syntax for date formatting, that more memorable than the syntax chosen in the time package in the go library.

Usage

	package main
	import (
		"gitlab.com/metakeule/fmtdate"
		"fmt"
	)

	func main() {
		date := fmtdate.Format("DD.MM.YYYY", time.Now())
		fmt.Println(date)

		var err
		date, err = fmtdate.Parse("M/D/YY", "2/3/07")
		fmt.Println(date, err)
	}

For json

    package main

    import (
        "gitlab.com/metakeule/fmtdate"
        "fmt"
        "encoding/json"
    )

    type Person struct {
        Name string
        BirthDay fmtdate.TimeDate
    }

    func main() {
        bday, err := fmtdate.NewTimeDate("YYYY-MM-DD", "2000-12-04")
        // do error handling
        paul := &Person{"Paul", bday}

        data, err := json.Marshal(paul)
        // do error handling
    }
