durafmt is a tiny Go library that formats time.Duration strings (and types) into a human readable format.

go get github.com/hako/durafmt

Why

If you've worked with time.Duration in Go, you most likely have come across this:

53m28.587093086s // :)

The above seems very easy to read, unless your duration looks like this:

354h22m3.24s // :S

Usage

durafmt.ParseString()

package main

import (
	"fmt"
	
	"github.com/hako/durafmt"
)

func main() {
	duration, err := durafmt.ParseString("354h22m3.24s")
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(duration) // 2 weeks 18 hours 22 minutes 3 seconds
	// duration.String() // String representation. "2 weeks 18 hours 22 minutes 3 seconds"
}

durafmt.ParseStringShort()

Version of durafmt.ParseString() that only returns the first part of the duration string.

package main

import (
	"fmt"
	
	"github.com/hako/durafmt"
)

func main() {
	duration, err := durafmt.ParseStringShort("354h22m3.24s")
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(duration) // 2 weeks
	// duration.String() // String short representation. "2 weeks"
}

durafmt.Parse()

package main

import (
	"fmt"
	"time"
	
	"github.com/hako/durafmt"
)

func main() {
	timeduration := (354 * time.Hour) + (22 * time.Minute) + (3 * time.Second)
	duration := durafmt.Parse(timeduration).String()
	fmt.Println(duration) // 2 weeks 18 hours 22 minutes 3 seconds
}

LimitFirstN()

Like durafmt.ParseStringShort() but for limiting the first N parts of the duration string.

package main

import (
	"fmt"
	"time"
	
	"github.com/hako/durafmt"
)

func main() {
	timeduration := (354 * time.Hour) + (22 * time.Minute) + (3 * time.Second)
	duration := durafmt.Parse(timeduration).LimitFirstN(2) // // limit first two parts.
	fmt.Println(duration) // 2 weeks 18 hours
}
