DESCRIPTION

   The HTTP::BrowserDetect object does a number of tests on an HTTP user
   agent string. The results of these tests are available via methods of
   the object.

   This module is based upon the JavaScript browser detection code
   available at
   http://www.mozilla.org/docs/web-developer/sniffer/browser_type.html.

CONSTRUCTOR AND STARTUP

new()

       HTTP::BrowserDetect->new( $user_agent_string )

   The constructor may be called with a user agent string specified.
   Otherwise, it will use the value specified by $ENV{'HTTP_USER_AGENT'},
   which is set by the web server when calling a CGI script.

SUBROUTINES/METHODS

user_agent()

   Returns the value of the user agent string.

   Calling this method with a parameter has now been deprecated and this
   feature will be removed in an upcoming release.

country()

   Returns the country string as it may be found in the user agent string.
   This will be in the form of an upper case 2 character code. ie: US, DE,
   etc

language()

   Returns the language string as it is found in the user agent string.
   This will be in the form of an upper case 2 character code. ie: EN, DE,
   etc

device()

   Returns the method name of the actual hardware, if it can be detected.
   Currently returns one of: android, audrey, avantgo, blackberry, dsi,
   iopener, ipad, iphone, ipod, kindle, n3ds, palm, ps3, psp, wap, webos.
   Returns undef if no hardware can be detected

device_name()

   Returns a human formatted version of the hardware device name. These
   names are subject to change and are really meant for display purposes.
   You should use the device() method in your logic. Returns one of:
   Android, Audrey, BlackBerry, Nintendo DSi, iopener, iPad, iPhone, iPod,
   Amazon Kindle, Nintendo 3DS, Palm, Sony PlayStation 3, Sony Playstation
   Portable, WAP capable phone, webOS. Also Windows-based smartphones will
   output various different names like HTC T7575. Returns undef if this is
   not a device or if no device name can be detected.

browser_properties()

   Returns a list of the browser properties, that is, all of the tests
   that passed for the provided user_agent string. Operating systems,
   devices, browser names, mobile and robots are all browser properties.

Detecting Browser Version

   Please note that that the version(), major() and minor() methods have
   been superceded as of release 1.07 of this module. They are not yet
   deprecated, but should be replaced with public_version(),
   public_major() and public_minor() in new development.

   The reasoning behind this is that version() method will, in the case of
   Safari, return the Safari/XXX numbers even when Version/XXX numbers are
   present in the UserAgent string. Because this behaviour has been in
   place for so long, some clients may have come to rely upon it. So, it
   has been retained in the interest of "bugwards compatibility", but in
   almost all cases, the numbers returned by public_version(),
   public_major() and public_minor() will be what you are looking for.

public_version()

   Returns the browser version (major and minor) as a string.

public_major()

   Returns the major part of the version as a string. For example, for
   Chrome 36.0.1985.67, this returns "36".

   Returns undef if no version information can be detected.

public_minor()

   Returns the minor part of the version as a string. This includes the
   decimal point; for example, for Chrome 36.0.1985.67, this returns ".0".

   Returns undef if no version information can be detected.

public_beta()

   Returns any part of the version after the major and minor version, as a
   string. For example, for Chrome 36.0.1985.67, this returns ".1985.67".
   The beta part of the string can contain any type of alphanumeric
   characters.

   Returns undef if no version information can be detected. Returns an
   empty string if version information is detected but it contains only a
   major and minor version with nothing following.

version($version)

   This is probably not what you want. Please use either public_version()
   or engine_version() instead.

   Returns the version as a string. If passed a parameter, returns true if
   it equals the browser major version.

   This function returns wrong values for some Safari versions, for
   compatibility with earlier code. public_version() returns correct
   version numbers for Safari.

major($major)

   This is probably not what you want. Please use either public_major() or
   engine_major() instead.

   Returns the integer portion of the browser version as a string. If
   passed a parameter, returns true if it equals the browser major
   version.

   This function returns wrong values for some Safari versions, for
   compatibility with earlier code. public_version() returns correct
   version numbers for Safari.

minor($minor)

   This is probably not what you want. Please use either public_minor() or
   engine_minor() instead.

   Returns the decimal portion of the browser version as a string.

   If passed a parameter, returns true if equals the minor version.

   This function returns wrong values for some Safari versions, for
   compatibility with earlier code. public_version() returns correct
   version numbers for Safari.

beta($beta)

   This is probably not what you want. Please use public_beta() instead.

   Returns the beta version, consisting of any characters after the major
   and minor version number, as a string.

   This function returns wrong values for some Safari versions, for
   compatibility with earlier code. public_version() returns correct
   version numbers for Safari.

Detecting Rendering Engine

engine_string()

   Returns one of the following:

   Gecko, KHTML, Trident, MSIE, NetFront

   Returns undef if no string can be found.

engine_version()

   Returns the version number of the rendering engine. Currently this only
   returns a version number for Gecko and Trident. Returns undef for all
   other engines. The output is simply engine_major added with
   engine_minor.

engine_major()

   Returns the major version number of the rendering engine. Currently
   this only returns a version number for Gecko and Trident. Returns undef
   for all other engines.

engine_minor()

   Returns the minor version number of the rendering engine. Currently
   this only returns a version number for Gecko and Trident. Returns undef
   for all other engines.

Detecting OS Platform and Version

   The following methods are available, each returning a true or false
   value. Some methods also test for the operating system version. The
   indentations below show the hierarchy of tests (for example, win2k is
   considered a type of winnt, which is a type of win32)

windows()

       win16 win3x win31
       win32
           winme win95 win98
           winnt
               win2k winxp win2k3 winvista win7
               win8
                   win8_0 win8_1
       wince
       winphone
           winphone7 winphone7_5 winphone8

     aix aix1 aix2 aix3 aix4 linux sco unixware mpras reliant
     dec sinix freebsd bsd

vms()

amiga()

ps3gameos()

pspgameos()

   It may not be possibile to detect Win98 in Netscape 4.x and earlier. On
   Opera 3.0, the userAgent string includes "Windows 95/NT4" on all Win32,
   so you can't distinguish between Win95 and WinNT.

os_string()

   Returns one of the following strings, or undef. This method exists
   solely for compatibility with the HTTP::Headers::UserAgent module.

     Win95, Win98, WinME, WinNT, Win2K, WinXP, Win2k3, WinVista, Win7, Win8,
     Win8.1, Windows Phone, Mac, Mac OS X, iOS, Win3x, OS2, Unix, Linux,
     Chrome OS, Firefox OS, Playstation 3 GameOS, Playstation Portable GameOS,
     RIM Tablet OS, BlackBerry 10

Detecting Browser Vendor

   The following methods are available, each returning a true or false
   value. Some methods also test for the browser version, saving you from
   checking the version separately.

 aol aol3 aol4 aol5 aol6

 chrome

 curl

 emacs

 firefox

 gecko

 icab

 ie ie3 ie4 ie4up ie5 ie5up ie55 ie55up ie6 ie7 ie8 ie9 ie10 ie11

 ie_compat_mode

   The ie_compat_mode is used to determine if the IE user agent is for the
   compatibility mode view, in which case the real version of IE is higher
   than that detected. The true version of IE can be inferred from the
   version of Trident in the engine_version method.

 java

 konqueror

 lotusnotes

 lynx links elinks

 mobile_safari

 mosaic

 mozilla

 neoplanet neoplanet2

 netfront

 netscape nav2 nav3 nav4 nav4up nav45 nav45up navgold nav6 nav6up

 opera opera3 opera4 opera5 opera6 opera7

 realplayer

   The realplayer method above tests for the presence of either the
   RealPlayer plug-in "(r1 " or the browser "RealPlayer".

 realplayer_browser

   The realplayer_browser method tests for the presence of the RealPlayer
   browser (but returns 0 for the plugin).

 safari

 staroffice

 webtv

   Netscape 6, even though its called six, in the User-Agent string has
   version number 5. The nav6 and nav6up methods correctly handle this
   quirk. The Firefox test correctly detects the older-named versions of
   the browser (Phoenix, Firebird).

browser_string()

   Returns undef on failure. Otherwise returns one of the following:

   Netscape, Firefox, Safari, Chrome, MSIE, WebTV, AOL Browser, Opera,
   Mosaic, Lynx, Links, ELinks, RealPlayer, IceWeasel, curl, puf,
   NetFront, Mobile Safari, BlackBerry, Obigo, Nintendo DSi, Nintendo 3DS,
   StarOffice, Lotus Notes, iCab, BrowseX, Silk.

gecko_version()

   If a Gecko rendering engine is used (as in Mozilla or Firefox), returns
   the version of the renderer (e.g. 1.3a, 1.7, 1.8) This might be more
   useful than the particular browser name or version when correcting for
   quirks in different versions of this rendering engine. If no Gecko
   browser is being used, or the version number can't be detected, returns
   undef.

Detecting Other Devices

   The following methods are available, each returning a true or false
   value.

 android

 audrey

 avantgo

 blackberry

 dsi

 iopener

 iphone

 ipod

 ipad

tablet()

   Returns true if the browser appears to belong to a tablet device.

robot()

   Returns true if the user agent appears to be a robot, spider, crawler,
   or other automated Web client.

   The following additional methods are available, each returning a true
   or false value. This is by no means a complete list of robots that
   exist on the Web.

TO DO

   The _engine() method currently only handles Gecko and Trident. It needs
   to be expanded to handle other rendering engines.

   POD coverage is also not 100%.

BUGS AND LIMITATIONS

   The biggest limitation at this point is the test suite, which really
   needs to have many more UserAgent strings to test against.

CONTRIBUTING

   Patches are certainly welcome, with many thanks for the excellent
   contributions which have already been received. The preferred method of
   patching would be to fork the GitHub repo and then send me a pull
   request, but plain old patch files are also welcome.

   If you're able to add test cases, this will speed up the time to
   release your changes. Just edit t/useragents.json so that the test
   coverage includes any changes you have made. Please contact me if you
   have any questions.

   This distribution uses Dist::Zilla. If you're not familiar with this
   module, please see
