ua-parser Build Status

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.

Other ua-parser Libraries

There are a few other libraries which make use of ua-parser's patterns. These include:

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"

Usage :: python

You can install ua-parser by running:

pip install pyyaml ua-parser

And 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'}

Usage :: java

import ua_parser.Parser;
import ua_parser.Client;

...

  String uaString = "Mozilla/5.0 (iPhone; CPU iPhone OS 5_1_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B206 Safari/7534.48.3";

  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"

Usage :: Pig

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.

REGISTER ua-parser-pig-0.1-SNAPSHOT-job.jar

DEFINE Device           ua_parser.pig.Device;
DEFINE Os               ua_parser.pig.Os;
DEFINE UserAgent        ua_parser.pig.UserAgent;

UserAgents =
    Load 'useragents.txt' AS (useragent:chararray);

AgentSpecs =
    FOREACH UserAgents
    GENERATE
             Device(useragent)              AS Device,
             Os(useragent)                  AS Os,
             UserAgent(useragent)           AS UserAgent,

             useragent                      AS Useragent;

DESCRIBE AgentSpecs;
DUMP AgentSpecs;

The versions that return only a single value:

REGISTER ua-parser-pig-0.1-SNAPSHOT-job.jar

DEFINE DeviceFamily     ua_parser.pig.device.Family;
DEFINE OsFamily         ua_parser.pig.os.Family;
DEFINE OsMajor          ua_parser.pig.os.Major;
DEFINE OsMinor          ua_parser.pig.os.Minor;

DEFINE UseragentMajor   ua_parser.pig.useragent.Major;
DEFINE UseragentMinor   ua_parser.pig.useragent.Minor;
DEFINE UseragentPatch   ua_parser.pig.useragent.Patch;

UserAgents =
    Load 'useragents.txt' AS (useragent:chararray);

AgentSpecs =
    FOREACH  UserAgents
    GENERATE DeviceFamily(useragent)    AS DeviceFamily:chararray,

             OsFamily(useragent)        AS OsFamily:chararray,
             OsMajor(useragent)         AS OsMajor:chararray,
             OsMinor(useragent)         AS OsMinor:chararray,
             OsPatch(useragent)         AS OsPatch:chararray,
             OsPatchMinor(useragent)    AS OsPatchMinor:chararray,

             UseragentFamily(useragent) AS UseragentFamily:chararray,
             UseragentMajor(useragent)  AS UseragentMajor:chararray,
             UseragentMinor(useragent)  AS UseragentMinor:chararray,
             UseragentPatch(useragent)  AS UseragentPatch:chararray,

             useragent                  AS Useragent;

DUMP AgentSpecs;

Usage :: Haskell

{-

Install via Hackage and cabal like so:

cabal update
cabal install ua-parser
Now you're good to go.

-}

{-# LANGUAGE OverloadedStrings #-}

module Main where

import Web.UAParser

-- A test string
test_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"

-- Main entry point for Haskell
main = do
    ua <- loadUAParser
    let uaResult = parseUA ua test_string
    print uaResult

    let osResult = parseOS ua test_string
    print osResult

-- Result from user agent parse
Just (UAResult {uarFamily = "Mobile Safari", uarV1 = Just "5", uarV2 = Just "1", uarV3 = Nothing})

-- Result from operating system parse
Just (OSResult {osrFamily = "iOS", osrV1 = Just "5", osrV2 = Just "1", osrV3 = Nothing, osrV4 = Nothing})

Please refer to Haddocks for more info; the API is pretty straightforward.

Usage :: Go

  testStr := "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_3; en-us; Silk/1.1.0-80) AppleWebKit/533.16 (KHTML, like Gecko) Version/5.0 Safari/533.16 Silk-Accelerated=true"
  regexFile := "../../regexes.yaml"
  parser := uaparser.New(regexFile)
  client := parser.Parse(testStr)
  fmt.Println(client.UserAgent.Family)  // "Amazon Silk"
  fmt.Println(client.UserAgent.Major)   // "1"
  fmt.Println(client.UserAgent.Minor)   // "1"
  fmt.Println(client.UserAgent.Patch)   // "0-80"
  fmt.Println(client.Os.Family)         // "Android"
  fmt.Println(client.Os.Major)          // ""
  fmt.Println(client.Os.Minor)          // ""
  fmt.Println(client.Os.Patch)          // ""
  fmt.Println(client.Os.PatchMinor)     // ""
