    Scrappy - The All Powerful Web Spidering, Scraping, Creeping Crawling

    version 0.94112090

        use Scrappy;

        my  $scraper = Scrappy->new;
                '/recent' => {
                    '#cpansearch li a' => sub {
                        print $_[1]->{href}, "\n";

    And now manually, ... without crawl, the above is similar to the
    following ...

        use Scrappy;

        my  $scraper = Scrappy->new;
        if ($scraper->get($url)->page_loaded) {
                $scraper->select('#cpansearch li a')->each(sub{
                    print shift->{href}, "\n";

    Scrappy is an easy (and hopefully fun) way of scraping, spidering,
    and/or harvesting information from web pages, web services, and more.
    Scrappy is a feature rich, flexible, intelligent web automation tool.

    Scrappy (pronounced Scrap+Pee) == 'Scraper Happy' or 'Happy Scraper'; If
    you like you may call it Scrapy (pronounced Scrape+Pee) although Python
    has a web scraping framework by that name and this module is not a port
    of that one.

    Scrappy provides a framework containing all the tools neccessary to
    create a simple yet powerful web scraper. At its core, Scrappy loads an
    array of features for access control, event logging, session handling,
    url matching, web request and response handling, proxy management, web
    scraping, and downloading.

    Futhermore, Scrappy provides a simple Moose-based plugin system that
    allows Scrappy to be easily extended.

        my  $scraper = Scrappy->new;
        $scraper->control;      # Scrappy::Scraper::Control (access control)
            $scraper->parser;       # Scrappy::Scraper::Parser (web scraper)
            $scraper->user_agent;   # Scrappy::Scraper::UserAgent (user-agent tools)
            $scraper->logger;       # Scrappy::Logger (event logger)
            $scraper->queue;        # Scrappy::Queue (flow control for loops)
            $scraper->session;      # Scrappy::Session (session management)

    Please see the METHODS section for a more in-depth look at all Scrappy

    The following is a list of object attributes available with every
    Scrappy instance, attributes always return an instance of the class they

    The content attribute holds the HTTP::Response object of the current
    request. Returns undef if no page has been successfully fetched.

        my  $scraper = Scrappy->new;

    The control attribute holds the Scrappy::Scraper::Control object which
    is used the provide access conrtol to the scraper.

        my  $scraper = Scrappy->new;
        ... $scraper->control->restrict('');
            ... $scraper->control->allow('');
            ... if $scraper->control->is_allowed($url);

    The debug attribute holds a boolean which controls whether event logs
    are captured.

        my  $scraper = Scrappy->new;

    The logger attribute holds the Scrappy::Logger object which is used to
    provide event logging capabilities to the scraper.

        my  $scraper = Scrappy->new;

    The parser attribute holds the Scrappy::Scraper::Parser object which is
    used to scrape html data from the specified source material.

        my  $scraper = Scrappy->new;

    The plugins attribute holds the Scrappy::Plugin object which is an
    interface used to load plugins.

        my  $scraper = Scrappy->new;

    The queue attribute holds the Scrappy::Queue object which is used to
    provide flow-control for the standard loop approach to crawling.

        my  $scraper = Scrappy->new;

    The session attribute holds the Scrappy::Session object which is used to
    provide session support and persistent data across executions.

        my  $scraper = Scrappy->new;

    The user_agent attribute holds the Scrappy::Scraper::UserAgent object
    which is used to set and manipulate the user-agent header of the

        my  $scraper = Scrappy->new;

    The worker attribute holds the WWW::Mechanize object which is used
    navigate web pages and provide request and response header information.

        my  $scraper = Scrappy->new;

    The back method is the equivalent of hitting the "back" button in a
    browser, it returns the previous page (response) and returns that URL,
    it will not backtrack beyond the first request.

        my  $scraper = Scrappy->new;
            my $last_url = $scraper->back;

    The cookies method returns an HTTP::Cookie object. Note! Cookies can be
    made persistent by enabling session-support. Session-support is enable
    by simply specifying a file to be used.

        my  $scraper = Scrappy->new;
        $scraper->session->write('session.yml'); # enable session support
        my  $cookies = $scraper->cookies;

    The crawl method is very useful when it is desired to crawl an entire
    website or at-least partially, it automates the tasks of creating a
    queue, fetching and parsing html pages, and establishing simple
    flow-control. See the SYNOPSIS for a simplified example, ... the
    following is a more complex example.

        my  $scrappy = Scrappy->new;
                '/recent' => {
                    '#cpansearch li a' => sub {
                        my ($self, $item) = @_;
                        # follow all recent modules from
                '/~:author/:name-:version/' => {
                    'body' => sub {
                        my ($self, $item, $args) = @_;
                    my $reviews = $self
                        ->select('.box table tr')->focus(3)->select('td.cell small a')
                    $reviews = $reviews =~ /\d+ Reviews/ ?
                            $reviews : '0 reviews';
                    print "found $args->{name} version $args->{version} ".
                            "[$reviews] by $args->{author}\n";

    The domain method returns the domain host of the current page. Local
    pages, e.g. file:///this/that/the_other will return undef.

        my  $scraper = Scrappy->new;
            print $scraper->domain; # print

    The download method is passed a URL, a Download Directory Path and a
    optionally a File Path, then it will follow the link and store the
    response contents into the specified file without leaving the current
    page. Basically it downloads the contents of the request (especially
    when the request pushes a file download). If a File Path is not
    specified, Scrappy will attempt to name the file automatically resorting
    to a random 6-charater string only if all else fails, then returns to
    the originating page.

        my  $scaper = Scrappy->new;
        my  $requested_url = '...';
        $scraper->download($requested_url, '/tmp');
        # supply your own file name
            $scraper->download($requested_url, '/tmp', 'somefile.txt');

    The dumper method is a convenience feature that passes the passed-in
    objects to Data::Dumper which in turn returns a stringified
    representation of that object/data-structure.

        my  $scaper = Scrappy->new;
        my  $requested_url = '...';
    my  $data = $scraper->select('//a[@href]')->data;
    # print out the scraped data
        print $scraper->dumper($data);

    The form method is used to submit a form on the current page.

        my  $scraper = Scrappy->new;
        $scraper->form(fields => {
                username => 'mrmagoo',
                password => 'foobarbaz'
        # or more specifically, for pages with multiple forms
        $scraper->form(form_name => 'login_form', fields => {
                username => 'mrmagoo',
                password => 'foobarbaz'
        $scraper->form(form_number => 1, fields => {
                username => 'mrmagoo',
                password => 'foobarbaz'

    The get method takes a URL or URI object, fetches a web page and returns
    the Scrappy object.

        my  $scraper = Scrappy->new;
    if ($scraper->get($new_url)->page_loaded) {
    # $self->content has the HTTP::Response object

    The log method logs an event with the event logger.

        my  $scraper = Scrappy->new;
        $scraper->debug(1); # unneccessary, on by default
            $scraper->logger->verbose(1); # more detailed log
        $scraper->log('error', 'Somthing bad happened');
        $scraper->log('info', 'Somthing happened');
            $scraper->log('warn', 'Somthing strange happened');
            $scraper->log('coolness', 'Somthing cool happened');

    Note! Event logs are always recorded but never automatically written to
    a file unless explicitly told to do so using the following:


    The page_content_type method returns the content_type of the current

        my  $scraper = Scrappy->new;
            print $scraper->page_content_type; # prints text/html

    The page_data method returns the HTML content of the current page,
    additionally this method when passed a string with HTML markup, updates
    the content of the current page with that data and returns the modified

        my  $scraper = Scrappy->new;
        my  $html = $scraper->page_data;

    The page_ishtml method returns true/false based on whether our content
    is HTML, according to the HTTP headers.

        my $scraper = Scrappy->new;
            if ($scraper->is_html) {

    The page_loaded method returns true/false based on whether the last
    request was successful.

        my $scraper = Scrappy->new;
            if ($scraper->page_loaded) {

    The page_match method checks the passed-in URL (or URL of the current
    page if left empty) against the URL pattern (route) defined. If URL is a
    match, it will return the parameters of that match much in the same way
    a modern web application framework processes URL routes.

        my $url = '';
    my $scraper = Scrappy->new;
    # match against the current page
        my $this = $scraper->page_match('/tags/:tag');
        if ($this) {
            print $this->{'tag'};
            # ... prints awesomeness
    .. or ..
    # match against a passed url
        my $this = $scraper->page_match('/tags/:tag', $url, {
            host => ''
    if ($this) {
            print "This is the ", $this->{tag}, " page";
            # ... prints this is the awesomeness page

    The page_reload method acts like the refresh button in a browser, it
    simply repeats the current request.

        my  $scraper = Scrappy->new;

    The page_status method returns the 3-digit HTTP status code of the

        my  $scraper = Scrappy->new;
        if ($scraper->page_status == 200) {

    The page_text method returns a text representation of the last page
    having all HTML markup stripped.

        my  $scraper = Scrappy->new;
    my  $text = $scraper->page_text;

    The page_title method returns the content of the title tag if the
    current page is HTML, otherwise returns undef.

        my  $scraper = Scrappy->new;
    my  $title = $scraper->page_title;
            print $title; # print Google

    This method sets breaks between your requests in an attempt to simulate
    human interaction.

        my  $scraper = Scrappy->new;

    Given the above example, there will be a 20 sencond break between each
    request made, get, post, request, etc., You can also specify a range to
    have the pause method select from at random...

        # reset/turn it off
        print "I slept for ", ($scraper->pause), " seconds";

    Note! The download method is exempt from any automatic pausing.

    The plugin method allow you to load a plugin. Using the appropriate case
    is recommended but not neccessary. See Scrappy::Plugin for more

        my $scraper = Scrappy->new;
    $scraper->plugin('foo_bar');    # will load Scrappy::Plugin::FooBar
        $scraper->plugin('foo-bar');    # will load Scrappy::Plugin::Foo::Bar
        $scraper->plugin('Foo::Bar');   # will load Scrappy::Plugin::Foo::Bar
    # more pratically
        $scraper->plugin('whois', 'spammer_check');
    ... somewhere in code
    my $var = $scraper->plugin_method();

        # example using core plugin Scrappy::Plugin::RandomProxy
    my  $s = Scrappy->new;

    The post method takes a URL, a hashref of key/value pairs, and
    optionally an array of key/value pairs, and posts that data to the
    specified URL, then returns an HTTP::Response object.

        my $scraper = Scrappy->new;

        $scraper->post($requested_url, {
            input_a => 'value_a',
            input_b => 'value_b'
    # w/additional headers
        my %headers = ('Content-Type' => 'multipart/form-data');
        $scraper->post($requested_url, {
            input_a => 'value_a',
            input_b => 'value_b'
        },  %headers);

    Note! The most common post headers for content-type are
    application/x-www-form-urlencoded and multipart/form-data.

    The proxy method will set the proxy for the next request to be tunneled

        my $scraper = Scrappy->new;
    $scraper->proxy('http', '');
    $scraper->proxy('http', 'ftp', '');
    # best practice when using proxies
    use Tiny::Try;
    my $proxie = Scrappy->new;
    $proxie->proxy('http', '');
    try {
        } catch {
            die "Proxy failed\n";

    Note! When using a proxy to perform requests, be aware that if they fail
    your program will die unless you wrap your code in an eval statement or
    use a try/catch mechanism. In the example above we use Tiny::Try to trap
    any errors that might occur when using proxy.

    The request_denied method is a simple shortcut to determine if the page
    you requested got loaded or redirected. This method is very useful on
    systems that require authentication and redirect if not authorized. This
    function return boolean, 1 if the current page doesn't match the
    requested page.

        my $scraper = Scrappy->new;
    if ($scraper->request_denied) {
            # do login, again
        else {
            # resume ...

    The response method returns the HTTP::Repsonse object of the current

        my  $scraper = Scrappy->new;
        my  $res = $scraper->response;

    The select method takes XPATH or CSS selectors and returns a
    Scrappy::Scraper::Parser object which contains the matching elements.

        my $scraper = Scrappy->new;
    # return a list of links
        my $list = $scraper->select('#profile li a')->data; # see Scrappy::Scraper::Parser
    foreach my $link (@{$list}) {
            print $link->{href}, "\n";
    # Zoom in on specific chunks of html code using the following ...
        my $list = $scraper
        ->select('#container table tr') # select all rows
        ->focus(4) # focus on the 5th row
        ->select('div div')->data;
    # The code above selects the div > div inside of the 5th tr in #container table
        # Access attributes html, text and other attributes as follows...
    $element = $scraper->select('table')->data->[0];
        $element->{html}; # HTML representation of the table
        $element->{text}; # Table stripped of all HTML
        $element->{cellpadding}; # cellpadding
        $element->{height}; # ...

    The stash method sets a stash (shared) variable or returns a reference
    to the entire stash object.

        my  $scraper = Scrappy->new;
            $scraper->stash(age => 31);
        print 'stash access works'
                if $scraper->stash('age') == $scraper->stash->{age};
    my  @array = (1..20);
            $scraper->stash(integers => [@array]);

    The store method stores the contents of the current page into the
    specified file. If the content-type does not begin with 'text', the
    content is saved as binary data.

        my  $scraper = Scrappy->new;

    The url method returns the complete URL for the current page.

        my  $scraper = Scrappy->new;
            print $scraper->url; # prints
