=head1 NAME

AnyEvent::WebDriver - control browsers using the W3C WebDriver protocol

=head1 SYNOPSIS

   # start geckodriver or any other w3c-compatible webdriver via the shell
   $ geckdriver -b myfirefox/firefox --log trace --port 4444

   # then use it
   use AnyEvent::WebDriver;

   # create a new webdriver object
   my $wd = new AnyEvent::WebDriver;

   # create a new session with default capabilities.
   $wd->new_session ({});

   $wd->navigate_to ("https://duckduckgo.com/html");
   my $searchbox = $wd->find_element ("css selector" => 'input[type="text"]');

   $wd->element_send_keys ($searchbox => "free software");
   $wd->element_click ($wd->find_element ("css selector" => 'input[type="submit"]'));

   sleep 10;

=head1 DESCRIPTION

This module aims to implement the W3C WebDriver specification which is the
standardised equivalent to the Selenium WebDriver API., which in turn aims
at remotely controlling web browsers such as Firefox or Chromium.

At the time of this writing, it was only available as a draft document, so
changes will be expected. Also, only F<geckodriver> did implement it, or
at least, most of it.

To make most of this module, or, in fact, to make any reasonable use of
this module, you would need to refer tot he W3C WebDriver document, which
can be found L<here|https://w3c.github.io/webdriver/>:

=head2 CREATING WEBDRIVER OBJECTS

=over

=item new AnyEvent::WebDriver key => value...

Create a new WebDriver object. Example for a remote webdriver connection
(the only type supported at the moment):

   my $wd = new AnyEvent::WebDriver host => "localhost", port => 4444;

Supported keys are:

=over

=item endpoint => $string

For remote connections, the endpoint to connect to (defaults to C<http://localhost:4444>).

=item proxy => $proxyspec

The proxy to use (same as the C<proxy> argument used by
L<AnyEvent::HTTP>). The default is C<undef>, which disables proxies. To
use the system-provided proxy (e.g. C<http_proxy> environment variable),
specify a value of C<default>.

=item autodelete => $boolean

If true (the default), then automatically execute C<delete_session> when
the WebDriver object is destroyed with an active session. IF set to a
false value, then the session will continue to exist.

=back

=cut

sub new {
   my ($class, %kv) = @_;

   bless {
      endpoint   => "http://localhost:4444",
      proxy      => undef,
      autodelete => 1,
      %kv,
   }, $class
}

sub DESTROY {
   my ($wdf) = @_;

   $wdf->delete_session
      if exists $wdf->{sid};
}

=back

=head2 SIMPLIFIED API

This section documents the simplified API, which is really just a very
thin wrapper around the WebDriver protocol commands. They all block (using
L<AnyEvent> condvars) the caller until the result is available, so must
not be called from an event loop callback - see L<EVENT BASED API> for an
alternative.

The method names are preetty much taken directly from the W3C WebDriver
specification, e.g. the request documented in the "Get All Cookies"
section is implemented via the C<get_all_cookies> method.

The order is the same as in the WebDriver draft at the tiome of this
writing, and only minimal massaging is done to request parameters and
results.

=head3 SESSIONS

=over

=cut

=item $wd->new_session ({ key => value... })

Try to connect to a webdriver and initialize session with a "new
session" command, passing the given key-value pairs as value
(e.g. C<capabilities>).

No session-dependent methods must be called before this function returns
successfully.

On success, C<< $wd->{sid} >> is set to the session id, and C<<
$wd->{capabilities} >> is set to the returned capabilities.

   my $wd = new AnyEvent::Selenium host => "localhost", port => 4545;

   $wd->new_session ({
      capabilities => {
         pageLoadStrategy => "normal",
      }.
   });

=cut

sub new_session_ {
   my ($wdf, $kv, $cb) = @_;

   local $wdf->{_ep} = "$wdf->{endpoint}/";
   $wdf->post_ (session => $kv, sub {
      my ($status, $res) = @_;

      if ($status eq "200") {
         $wdf->{sid}          = $res->{sessionId};
         $wdf->{capabilities} = $res->{capabilities};

         $wdf->{_ep} = "$wdf->{endpoint}/session/$wdf->{sid}/";
      }

      $cb->($status, $res);
   });
}

=item $wd->delete_session

Deletes the session - the WebDriver object must not be used after this
call.

=cut

sub delete_session_ {
   my ($wdf, $cb) = @_;

   local $wdf->{_ep} = "$wdf->{endpoint}/session/$wdf->{sid}";
   $wdf->delete_ ("" => $cb);
}

=item $timeouts = $wd->get_timeouts

Get the current timeouts, e.g.:

   # { implicit => 0, pageLoad => 300000, script => 30000 }

=head2 EVENT BASED API

This module wouldn't be a good AnyEvent citizen if it didn't have a true
event-based API.

In fact, the simplified API, as documented above, is emulated via the
event-based API and an C<AUTOLOAD> function that automatically provides
blocking wrappers around the callback-based API.

Every method documented in the L<SIMPLIFIED API> section has an equivalent
event-based method that is formed by appending a underscore (C<_>) to the
method name, and appending a callback to the argument list (mnemonic: the
underscore indicates the "the action is not yet finished" after the call
returns).

For example, instead of a blocking calls to C<new_session>, C<navigate_to>
and C<back>, you can make a callback-based ones:

   my $cv = AE::cv;

   $wd->new_session ({}, sub {
      my ($status, $value) = @_,

      die "error $value->{error}" if $status ne "200";

      $wd->navigate_to_ ("http://www.nethype.de", sub {

         $wd->back_ (sub {
            print "all done\n";
            $cv->send;
         });

      });
   });

   $cv->recv;

While the blocking methods C<croak> on errors, the callback-based ones all
pass two values to the callback, C<$status> and C<$res>, where C<$status>
is the HTTP status code (200 for successful requests, typically 4xx ot
5xx for errors), and C<$res> is the value of the C<value> key in the JSON
response object.

Other than that, the underscore variants and the blocking variants are
identical.

=head2 LOW LEVEL API

All the simplfiied API methods are very thin wrappers around WebDriver
commands of the same name. Theyx are all implemented in terms of the
low-level methods (C<req>, C<get>, C<post> and C<delete>), which exists
in blocking and callback-based variants (C<req_>, C<get_>, C<post_> and
C<delete_>).

Examples are after the function descriptions.

=over

=item $wd->req_ ($method, $uri, $body, $cb->($status, $value))

=item $value = $wd->req ($method, $uri, $body)

Appends the C<$uri> to the C<endpoint/session/{sessionid}/> URL and makes
a HTTP C<$method> request (C<GET>, C<POST> etc.). C<POST> requests can
provide a UTF-8-encoded JSON text as HTTP request body, or the empty
string to indicate no body is used.

For the callback version, the callback gets passed the HTTP status code
(200 for every successful request), and the value of the C<value> key in
the JSON response object as second argument.

=item $wd->get_ ($uri, $cb->($status, $value))

=item $value = $wd->get ($uri)

Simply a call to C<req_> with C<$method> set to C<GET> and an empty body.

=item $wd->post_ ($uri, $data, $cb->($status, $value))

=item $value = $wd->post ($uri, $data)

Simply a call to C<req_> with C<$method> set to C<POST> - if C<$body> is
C<undef>, then an empty object is send, otherwise, C<$data> must be a
valid request object, which gets encoded into JSON for you.

=item $wd->delete_ ($uri, $cb->($status, $value))

=item $value = $wd->delete ($uri)

Simply a call to C<req_> with C<$method> set to C<DELETE> and an empty body.

Example: implement C<get_all_cookies>, which is a simple C<GET> request
without any parameters:

   $cookies = $wd->get ("cookie");

Example: implement C<execute_script>, which needs some parameters:

   $results = $wd->post ("execute/sync" => { script => "$javascript", args => [] });

Example: call C<find_elements> to find all C<IMG> elements, stripping the
returned element objects to only return the element ID strings:

   my $elems = $wd->post (elements => { using => "css selector", value => "img" });

   # yes, the W3C found an interetsing way around the typelessness of JSON
   $_ = $_->{"element-6066-11e4-a52e-4f735466cecf"}
      for @$elems;

=head1 HISTORY

This module was unintentionally created (it started inside some quickly
hacked-together script) simply because I couldn't get the existing
C<Selenium::Remote::Driver> module to work, ever, despite multiple
attempts over the years and trying to report multiple bugs, which have
been completely ignored. It's also not event-based, so, yeah...
