# UserAgent [](https://travis-ci.org/mssola/user_agent) [](http://godoc.org/github.com/mssola/user_agent)
UserAgent is a Go library that parses HTTP User Agents.
## Usage
~~~ go
package main
import (
"fmt"
"github.com/mssola/user_agent"
)
func main() {
// The "New" function will create a new UserAgent object and it will parse
// the given string. If you need to parse more strings, you can re-use
// this object and call: ua.Parse("another string")
ua := user_agent.New("Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.97 Safari/537.11");
fmt.Printf("%v\n", ua.Mobile()) // => false
fmt.Printf("%v\n", ua.Bot()) // => false
fmt.Printf("%v\n", ua.Mozilla()) // => "5.0"
fmt.Printf("%v\n", ua.Platform()) // => "X11"
fmt.Printf("%v\n", ua.OS()) // => "Linux x86_64"
name, version := ua.Engine()
fmt.Printf("%v\n", name) // => "AppleWebKit"
fmt.Printf("%v\n", version) // => "537.11"
name, version = ua.Browser()
fmt.Printf("%v\n", name) // => "Chrome"
fmt.Printf("%v\n", version) // => "23.0.1271.97"
// Let's see an example with a bot.
ua.Parse("Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)")
fmt.Printf("%v\n", ua.Bot()) // => true
name, version = ua.Browser()
fmt.Printf("%v\n", name) // => Googlebot
fmt.Printf("%v\n", version) // => 2.1
}
