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()
|
||
|
|
|
||
|
|
```go
|
||
|
|
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.
|
||
|
|
|
||
|
|
```go
|
||
|
|
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()
|
||
|
|
|
||
|
|
```go
|
||
|
|
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.
|
||
|
|
|
||
|
|
```go
|
||
|
|
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
|
||
|
|
}
|
||
|
|
```
