expandhost
Expand host pattern to host list.
E.g.:
Expand foo[01-03,06,10-12].[beijing,wuhan].bar.com, the result will be as follows:
[]string{
"foo01.beijing.bar.com",
"foo01.wuhan.bar.com",
"foo02.beijing.bar.com",
"foo02.wuhan.bar.com",
"foo03.beijing.bar.com",
"foo03.wuhan.bar.com",
"foo06.beijing.bar.com",
"foo06.wuhan.bar.com",
"foo10.beijing.bar.com",
"foo10.wuhan.bar.com",
"foo11.beijing.bar.com",
"foo11.wuhan.bar.com",
"foo12.beijing.bar.com",
"foo12.wuhan.bar.com",
}
Usage
import "github.com/go-project-pkg/expandhost"
func main() {
pattern := "foo[01-03,06,10-12].[beijing,wuhan].bar.com"
hosts, err := expandhost.PatternToHosts(pattern)
if err != nil {
fmt.Println(err)
}
fmt.Printf("%v\n", hosts)
}
Output:
[foo01.beijing.bar.com foo01.wuhan.bar.com foo02.beijing.bar.com foo02.wuhan.bar.com foo03.beijing.bar.com foo03.wuhan.bar.com foo06.beijing.bar.com foo06.wuhan.bar.com foo10.beijing.bar.com foo10.wuhan.bar.com foo11.beijing.bar.com foo11.wuhan.bar.com foo12.beijing.bar.com foo12.wuhan.bar.com]
