ua-parser is a multi-language port of BrowserScope's user agent string parser.
The crux of the original parser--the data collected by Steve Souders over the years--has been extracted into a separate YAML file so as to be reusable as is by implementations in other programming languages.
ua-parser is just a small wrapper around this data.

There are a few other libraries which make use of ua-parser's patterns. These include:
- Ruby - user_agent_parser
Usage :: node.js
var r = require('ua-parser').parse(navigator.userAgent);
console.log(r.ua.toString()); // -> "Safari 5.0.1"
console.log(r.ua.toVersionString()); // -> "5.0.1"
console.log(r.ua.family) // -> "Safari"
console.log(r.ua.major); // -> "5"
console.log(r.ua.minor); // -> "0"
console.log(r.ua.patch); // -> "1"
console.log(r.os.toString()); // -> "iOS 5.1"
console.log(r.os.toVersionString()); // -> "5.1"
console.log(r.os.family) // -> "iOS"
console.log(r.os.major); // -> "5"
console.log(r.os.minor); // -> "1"
console.log(r.os.patch); // -> null
console.log(r.device.family); // -> "iPhone"Note if you're only interested in one of the ua, device or os objects, you will getter better performance by using the more specific methods (uaParser.parseUA, uaParser.parseOS and uaParser.parseDevice respectively), e.g.:
var p = require('ua-parser');
console.log(p.parseUA(navigator.userAgent).toString());
// -> "Safari 5.0.1"
console.log(p.parseOS(navigator.userAgent).toString());
// -> "iOS 5.1"
console.log(p.parseDevice(navigator.userAgent).toString());
// -> "iPhone"You can install ua-parser by running:
pip install pyyaml ua-parserAnd here's how to use it:
from ua_parser import user_agent_parser
# On the server, you could use a WebOB request object.
user_agent_string = request.META.get('HTTP_USER_AGENT')
# For demonstration purposes, though an iPhone ...
user_agent_string = 'Mozilla/5.0 (iPhone; CPU iPhone OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B179 Safari/7534.48.3'
# Get back a big dictionary of all the goodies.
result_dict = user_agent_parser.Parse(user_agent_string)
print result_dict['user_agent']
# {'major': '5', 'minor': '1', 'family': 'Mobile Safari', 'patch': None}
print result_dict['os']
# {'major': '5', 'patch_minor': None, 'minor': '1', 'family': 'iOS', 'patch': None}
print result_dict['device']
# {'family': 'iPhone'}import ua_parser.Parser;
import ua_parser.Client;

Parser uaParser = new Parser();
Client c = uaParser.parse(uaString);
System.out.println(c.userAgent.family); // => "Mobile Safari"
System.out.println(c.userAgent.major); // => "5"
System.out.println(c.userAgent.minor); // => "1"
System.out.println(c.os.family); // => "iOS"
System.out.println(c.os.major); // => "5"
System.out.println(c.os.minor); // => "1"
System.out.println(c.device.family); // => "iPhone"For Pig there are UDFs for getting a single value and UDFs for getting a tuple with all values for either Device, Os of UserAgent. For most usecases the tuple UDFs will be the most useful.
