|
||||
The use of [pflag](https://github.com/spf13/pflag/) in Viper does not preclude
|
||||
the use of other packages that use the [flag](https://golang.org/pkg/flag/)
|
||||
package from the standard library. The pflag package can handle the flags
|
||||
defined for the flag package by importing these flags. This is accomplished
|
||||
by a calling a convenience function provided by the pflag package called
|
||||
AddGoFlagSet().
|
||||
|
||||
Example:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"flag"
|
||||
"github.com/spf13/pflag"
|
||||
)
|
||||
|
||||
func main() {
|
||||
pflag.CommandLine.AddGoFlagSet(flag.CommandLine)
|
||||
pflag.Parse()
|
||||
...
|
||||
}
|
||||
```
|
||||
