A string can be retrieved by adding `.String()` to a variable, such as `uasurfer.BrowserName.String()`. + +``` +// Define a user agent string +myUA := "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.85 Safari/537.36" + +// Parse() returns all attributes, including returning the full UA string last +ua, uaString := uasurfer.Parse(myUA) +``` + +where example UserAgent is: +``` +{ + Browser { + BrowserName: BrowserChrome, + Version: { + Major: 45, + Minor: 0, + Patch: 2454, + }, + }, + OS { + Platform: PlatformMac, + Name: OSMacOSX, + Version: { + Major: 10, + Minor: 10, + Patch: 5, + }, + }, + DeviceType: DeviceComputer, +} +``` + +**Usage note:** There are some OSes that do not return a version, see docs below. Linux is typically not reported with a specific Linux distro name or version. + +#### Browser Name +* `BrowserChrome` - Google [Chrome](https://en.wikipedia.org/wiki/Google_Chrome), [Chromium](https://en.wikipedia.org/wiki/Chromium_(web_browser)) +* `BrowserSafari` - Apple [Safari](https://en.wikipedia.org/wiki/Safari_(web_browser)), Google Search ([GSA](https://itunes.apple.com/us/app/google/id284815942)) +* `BrowserIE` - Microsoft [Internet Explorer](https://en.wikipedia.org/wiki/Internet_Explorer), [Edge](https://en.wikipedia.org/wiki/Microsoft_Edge) +* `BrowserFirefox` - Mozilla [Firefox](https://en.wikipedia.org/wiki/Firefox), GNU [IceCat](https://en.wikipedia.org/wiki/GNU_IceCat), [Iceweasel](https://en.wikipedia.org/wiki/Mozilla_Corporation_software_rebranded_by_the_Debian_project#Iceweasel), [Seamonkey](https://en.wikipedia.org/wiki/SeaMonkey) +* `BrowserAndroid` - Android [WebView](https://developer.chrome.com/multidevice/webview/overview) (Android OS <4.4 only) +* `BrowserOpera` - [Opera](https://en.wikipedia.org/wiki/Opera_(web_browser)) +* `BrowserUCBrowser` - [UC Browser](https://en.wikipedia.org/wiki/UC_Browser) +* `BrowserSilk` - Amazon [Silk](https://en.wikipedia.org/wiki/Amazon_Silk) +* `BrowserSpotify` - [Spotify](https://en.wikipedia.org/wiki/Spotify#Clients) desktop client +* `BrowserBlackberry` - RIM [BlackBerry](https://en.wikipedia.org/wiki/BlackBerry) +* `BrowserUnknown` - Unknown + +#### Browser Version + +Browser version returns an `unint8` of the major version attribute of the User-Agent String. For example Chrome 45.0.23423 would return `45`. The intention is to support math operators with versions, such as "do XYZ for Chrome version >23". + +Unknown version is returned as `0`. + +#### Platform +* `PlatformWindows` - Microsoft Windows +* `PlatformMac` - Apple Macintosh +* `PlatformLinux` - Linux, including Android and other OSes +* `PlatformiPad` - Apple iPad +* `PlatformiPhone` - Apple iPhone +* `PlatformBlackberry` - RIM Blackberry +* `PlatformWindowsPhone` Microsoft Windows Phone & Mobile +* `PlatformKindle` - Amazon Kindle & Kindle Fire +* `PlatformPlaystation` - Sony Playstation, Vita, PSP +* `PlatformXbox` - Microsoft Xbox - `PlatformXbox` +* `PlatformNintendo` - Nintendo DS, Wii, etc. +* `PlatformUnknown` - Unknown + +#### OS Name +* `OSWindows` +* `OSMacOSX` - includes "macOS Sierra" +* `OSiOS` +* `OSAndroid` +* `OSChromeOS` +* `OSWebOS` +* `OSLinux` +* `OSPlaystation` +* `OSXbox` +* `OSNintendo` +* `OSUnknown` + +#### OS Version + +OS X major version is alway 10 with consecutive minor versions indicating release releases (10 - Yosemite, 11 - El Capitain, 12 Sierra, etc). Windows version is NT version. `Version{0, 0, 0}` indicated version is unknown or not evaluated. +Versions can be compared using `Less` function: `if ver1.Less(ver2) {}` + +Here are some examples across the platform, os.name, and os.version: + +* For Windows XP (Windows NT 5.1), "`PlatformWindows`" is the platform, "`OSWindows`" is the name, and `{5, 1, 0}` the version. +* For OS X 10.5.1, "`PlatformMac`" is the platform, "`OSMacOSX`" the name, and `{10, 5, 1}` the version. +* For Android 5.1, "`PlatformLinux`" is the platform, "`OSAndroid`" is the name, and `{5, 1, 0}` the version. +* For iOS 5.1, "`PlatformiPhone`" or "`PlatformiPad`" is the platform, "`OSiOS`" is the name, and `{5, 1, 0}` the version. + +###### Windows Version Guide + +* Windows 10 - `{10, 0, 0}` +* Windows 8.1 - `{6, 3, 0}` +* Windows 8 - `{6, 2, 0}` +* Windows 7 - `{6, 1, 0}` +* Windows Vista - `{6, 0, 0}` +* Windows XP - `{5, 1, 0}` or `{5, 2, 0}` +* Windows 2000 - `{5, 0, 0}` + +Windows 95, 98, and ME represent 0.01% of traffic worldwide and are not available through this package at this time. + +#### DeviceType +DeviceType is typically quite accurate, though determining between phones and tablets on Android is not always possible due to how some vendors design their UA strings. A mobile Android device without tablet indicator defaults to being classified as a phone.
