# NAME Wight - Communicate with PhantomJS # SYNOPSIS use Wight; my $wight = Wight->new; $wight->visit('http://example.com/'); $wight->evaluate('document.title'); # => evaluates JavaScript expression $wight->find('//a[@rel="next"]')->click; # DESCRIPTION Wight provides methods for operating PhantomJS from Perl, especially intended to be used testing web application. For client side scripting, uses [poltergeist](https://github.com/jonleighton/poltergeist)'s JavaScript. # WARNING __This module is currently under development and interfaces are subject to change.__ # INITIALIZATION my $wight = Wight->new(%args); _%args_ accepts keys below: - autorun => 1 Automatically runs PhantomJS and waits for it. Defaults to true, otherwise you will call `handshake` explicitly. - phantomjs => 'phantomjs' Specifies PhantomJS command. Defaults to 'phantomjs'. - cookie\_jar => $HTTP\_Cookies Supply browser cookies. # BROWSER METHODS Every method croaks if the operation failed. - $wight->visit($path) Opens a web page. - my $result = $wight->evaluate($javascript\_expression) Evaluates a JavaScript expression and returns its result. - $wight->execute($javascript\_statement) Executes JavaScript statements. - my $node = $wight->find($xpath) - my @nodes = $wight->find($xpath) Finds a node within current page and returns a (list of) [Wight::Node](http://search.cpan.org/perldoc?Wight::Node). - $wight->render($file) Renders current page to local file. # NODE METHODS Every method croaks if the operation was failed. - $node->click - my $text = $node->text - $node->set($value) # INITIALIZATION METHODS - my $port = $wight->spawn\_psgi($file\_or\_code) Forks and runs specified PSGI application. Sets its `base_url` to "http://localhost:_$port_/". - $wight->handshake Starts PhantomJS and waits for communication established. After this, you can call BROWSER METHODS above. - $wight->base\_url($url); # UTILITY METHODS - $wight->sleep($secs) - $wight->wait\_until(\\&code) Stops execution until _code_ returns a true value. # AUTHOR motemen # SEE ALSO [Poltergeist](https://github.com/jonleighton/poltergeist) # LICENSE ## Wight itself (Perl part): This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself. ## JavaScripts from Poltergeist: Copyright (c) 2011 Jonathan Leighton Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
