// Debug mode\r
// ----------------------\r
// Enable or disable debugging. When enabled debugging works by passing\r
// &debug to the makefulltextfeed.php querystring.\r

// Max entries (without access key)\r
// ----------------------\r
// The maximum number of feed items to process when no access key is supplied.\r
// This limits the user-supplied &max=x value. For example, if the user\r

// Exclude items if extraction fails\r
// ---------------------------------\r
// Excludes items from the resulting feed\r
// if we cannot extract any content from the\r
// item URL.\r
// Possible values...\r
// Enable: true\r
// Disable: false (default)\r
// User decides: 'user' (this option will appear on the form)\r

// in a site config file.\r

\r
// Enable caching\r
// ----------------------\r
// Enable this if you'd like to cache results\r
// for 10 minutes. Cache files are written to disk (in cache/ subfolders\r
// - which must be writable).\r
// Initially it's best to keep this disabled to make sure everything works\r
// as expected. If you have APC enabled, please also see smart_cache in the\r

// Values will be placed inside the <dc:language> element inside each <item> element\r
// Possible values:\r
// * Ignore language: 0\r
// * Use article/feed metadata (e.g. HTML lang attribute): 1 (default)\r
// * As above, but guess if not present: 2\r
// * Always guess: 3\r
// * User decides: 'user' (value of 0-3 can be passed in querystring: e.g. &l=2)\r

\r
// Registration key\r
// ---------------\r
// The registration key is optional. It is not required to use Full-Text RSS, \r
// and does not affect the normal operation of Full-Text RSS. It is currently \r
// only used on admin pages which help you update site patterns with the \r
// latest version offered by FiveFilters.org. For these admin-related \r
// tasks to complete, we will require a valid registration key.\r
// If you would like one, you can purchase the latest version of Full-Text RSS\r
// at http://fivefilters.org/content-only/\r
// Your registration key will automatically be sent in the confirmation email.\r
// Once you have it, simply copy and paste it here.\r

// ----------------------\r

// To use these pages, enter a password here and you'll be prompted for it when you try to access those pages.\r
// If no password or username is set, pages requiring admin privelages will be inaccessible. \r
// The default username is 'admin'.\r
// If overriding with an environment variable, separate username and password with a colon, e.g.:\r

\r
// Favour item titles in feed\r
// ----------------------\r
// By default, when processing feeds, we assume item titles in the feed\r
// have not been truncated. So after processing web pages, the extracted titles\r
// are not used in the generated feed. If you prefer to have extracted titles in \r
// the feed you can either set this to false, in which case we will always favour \r
// extracted titles. Alternatively, if set to 'user' (default) we'll use the \r
// extracted title if you pass '&use_extracted_title' in the querystring.\r
// Possible values:\r
// * Favour feed titles: true \r
// * Favour extracted titles: false\r
// * Favour feed titles with user override: 'user' (default)\r
// Note: this has no effect when the input URL is to a web page - in these cases\r
// we always use the extracted title in the generated feed.\r
$options->favour_feed_titles = 'user';\r
\r
// Access keys (password protected access)\r
// ------------------------------------\r
// NOTE: You do not need an API key from fivefilters.org to run your own \r
// copy of the code. This is here if you'd like to restrict access to\r
// _your_ copy.\r
// Keys let you group users - those with a key and those without - and\r
// restrict access to the service to those without a key.\r
// If you want everyone to access the service in the same way, you can\r
// leave the array below empty and ignore the access key options further down.\r
// The options further down let you control how the service should behave \r
// in each mode.\r
// Note: Explicitly including the index number (1 and 2 in the examples below) \r
// is highly recommended (when generating feeds, we encode the key and \r
// refer to it by index number and hash).\r

/// ADVANCED OPTIONS ////////////////////////////\r
/////////////////////////////////////////////////\r
\r
// Enable XSS filter?\r
// ----------------------\r
// We have not enabled this by default because we assume the majority of\r
// our users do not display the HTML retrieved by Full-Text RSS\r
// in a web page without further processing. If you subscribe to our generated\r
// feeds in your news reader application, it should, if it's good software, already\r
// filter the resulting HTML for XSS attacks, making it redundant for\r
// Full-Text RSS do the same. Similarly with frameworks/CMS which display\r
// feed content - the content should be treated like any other user-submitted content.\r
// \r
// If you are writing an application yourself which is processing feeds generated by\r
// Full-Text RSS, you can either filter the HTML yourself to remove potential XSS attacks\r
// or enable this option. This might be useful if you are processing our generated\r
// feeds with JavaScript on the client side - although there's client side xss\r
// filtering available too, e.g. https://code.google.com/p/google-caja/wiki/JsHtmlSanitizer\r
// \r
// If enabled, we'll pass retrieved HTML content through htmLawed with\r
// safe flag on and style attributes denied, see\r
// http://www.bioinformatics.org/phplabware/internal_utilities/htmLawed/htmLawed_README.htm#s3.6\r
// Note: if enabled this will also remove certain elements you may want to preserve, such as iframes.\r
//\r
// Valid values:\r
// true - enabled, all content will be filtered\r
// 'user' (default) - user must pass &xss in makefulltextfeed.php querystring to enable\r
// false - disabled\r
$options->xss_filter = 'user';\r
\r
// Allowed parsers\r
// ----------------------\r
// Full-Text RSS attempts to use PHP's libxml extension to process HTML.\r
// While fast, on some sites it may not always produce good results. \r
// For these sites, you can specify an alternative HTML parser: \r
// parser: html5lib\r
// The html5lib parser is bundled with Full-Text RSS.\r
// see http://code.google.com/p/html5lib/\r
//\r
// To disable HTML parsing with html5lib, you can remove it from this list.\r
// By default we allow both: libxml and html5lib.\r
$options->allowed_parsers = array('libxml', 'html5lib');\r
//$options->allowed_parsers = array('libxml'); //disable html5lib - forcing libxml in all cases\r
\r
// Enable Cross-Origin Resource Sharing (CORS)\r
// ----------------------\r
// If enabled we'll send the following HTTP header\r
// Access-Control-Allow-Origin: *\r
// see http://en.wikipedia.org/wiki/Cross-origin_resource_sharing\r
$options->cors = false;\r
\r
// Use APC user cache?\r
// ----------------------\r
// If enabled we will store site config files (when requested \r
// for the first time) in APC's user cache. Keys prefixed with 'sc.'\r
// This improves performance by reducing disk access.\r
// Note: this has no effect if APC is unavailable on your server.\r
$options->apc = true;\r
\r
// Smart cache (experimental)\r
// ----------------------\r
// With this option enabled we will not cache to disk immediately.\r
// We will store the cache key in APC and if it's requested again\r
// we will cache results to disk. Keys prefixed with 'cache.'\r
// This improves performance by reducing disk access.\r
// Note: this has no effect if APC is disabled or unavailable on your server,\r
// or if you have caching disabled.\r
$options->smart_cache = true;\r
\r
// Fingerprints\r
// ----------------------\r
// key is fingerprint (fragment to find in HTML)\r
// value is host name to use for site config lookup if fingerprint matches\r

	// Posterous\r
	'<meta name="generator" content="Posterous"' => array('hostname'=>'fingerprint.posterous.com', 'head'=>true),\r

// URL Rewriting\r
// ----------------------\r
// Currently allows simple string replace of URLs.\r
// Useful for rewriting certain URLs to point to a single page\r
// or HTML view. Although using the single_page_link site config\r
// instruction is the preferred way to do this, sometimes, as\r
// with Google Docs URLs, it's not possible.\r
// Note: this might move to the site config file at some point.\r
$options->rewrite_url = array(\r
	// Rewrite public Google Docs URLs to point to HTML view:\r
	// if a URL contains docs.google.com, replace /Doc? with /View?\r

	'm.vanityfair.com' => array('m.vanityfair.com' => 'www.vanityfair.com')\r
);\r
\r
// Content-Type exceptions\r
// -----------------------\r
// Here you can define different actions based\r
// on the Content-Type header returned by server.\r
// MIME type as key, action as value.\r
// Valid actions:\r
// * 'exclude' - exclude this item from the result\r
// * 'link' - create HTML link to the item\r

							   'video' => array('action'=>'link', 'name'=>'Video')\r
							  );\r
\r
// Cache directory level\r
// ----------------------\r
// Spread cache files over different directories (only used if caching is enabled).\r
// Used to prevent large number of files in one directory.\r
// This corresponds to Zend_Cache's hashed_directory_level\r
// see http://framework.zend.com/manual/en/zend.cache.backends.html\r
// It's best not to change this if you're unsure.\r
$options->cache_directory_level = 0;\r
\r
// Cache cleanup\r
// -------------\r
// 0 = script will not clean cache (rename cachecleanup.php and use it for scheduled (e.g. cron) cache cleanup)\r
// 1 = clean cache everytime the script runs (not recommended)\r
// 100 = clean cache roughly once every 100 script runs\r
// x = clean cache roughly once every x script runs\r
// ...you get the idea :)\r
