<?php
/* Full-Text RSS config */
// ......IMPORTANT......................................
// .....................................................
// Please do not change this file (config.php) directly.
// Save a copy as custom_config.php and make your
// changes to that instead. It will automatically
// override anything in config.php. Because config.php
// always gets loaded anyway, you can simply specify
// options you'd like to override in custom_config.php.
// .....................................................
// Create config object
if (!isset($options)) $options = new stdClass();
// Enable service
// ----------------------
// Set this to false if you want to disable the service.
// If set to false, no feed is produced and users will
// be told that the service is disabled.
$options->enabled = true;
// Debug mode
// ----------------------
// Enable or disable debugging. When enabled debugging works by passing
// &debug to the makefulltextfeed.php querystring.
// Valid values:
// true or 'user' (default) - let user decide
// 'admin' - debug works only for logged in admin users
// false - disabled
$options->debug = true;
// Default entries (without access key)
// ----------------------
// The number of feed items to process when no API key is supplied
// and no &max=x value is supplied in the querystring.
$options->default_entries = 5;
// Max entries (without access key)
// ----------------------
// The maximum number of feed items to process when no access key is supplied.
// This limits the user-supplied &max=x value. For example, if the user
// asks for 20 items to be processed (&max=20), if max_entries is set to
// 10, only 10 will be processed.
$options->max_entries = 10;
// Full content
// ----------------------
// By default Full-Text RSS includes the extracted content in the output.
// You can exclude this from the output by passing '&content=0' in the querystring.
//
// Possible values...
// Always include: true
// Never include: false
// Include unless user overrides (&content=0): 'user' (default)
//
// Note: currently this does not disable full content extraction. It simply omits it
// from the output.
$options->content = 'user';
// Excerpts
// ----------------------
// By default Full-Text RSS does not include excerpts in the output.
// You can enable this by passing '&summary=1' in the querystring.
// This will include a plain text excerpt from the extracted content.
//
// Possible values...
// Always include: true (recommended for new users)
// Never include: false
// Don't include unless user overrides (&summary=1): 'user' (default)
//
// Important: if both content and excerpts are requested, the excerpt will be
// placed in the description element and the full content inside content:encoded.
// If excerpts are not requested, the full content will go inside the description element.
//
// Why are we not returning both excerpts and content by default?
// Mainly for backward compatibility.
// Excerpts should appear in the feed item's description element. Previous versions
// of Full-Text RSS did not return excerpts, so the description element was always
// used for the full content (as recommended by the RSS advisory). When returning both,
// we need somewhere else to place the content (content:encoded).
// Having both enabled should not create any problems for news readers, but it may create
// problems for developers upgrading from one of our earlier versions who may now find
// their applications are returning excerpts instead of the full content they were
// expecting. To avoid such surprises for users who are upgrading Full-Text RSS,
// excerpts must be explicitly requested in the querystring by default.
//
// Why not use a different element name for excerpts?
// According to the RSS advisory:
// "Publishers who employ summaries should store the summary in description and
// the full content in content:encoded, ordering description first within the item.
// On items with no summary, the full content should be stored in description."
// See: http://www.rssboard.org/rss-profile#namespace-elements-content-encoded
//
// For more consistent element naming, we recommend new users set this option to true.
// The full content can still be excluded via the querystring, but the element names
// will not change: when $options->summary = true, the description element will always
// be reserved for the excerpt and content:encoded always for full content.
$options->summary = 'user';
// Rewrite relative URLs
// ----------------------
// With this enabled relative URLs found in the extracted content
// block are automatically rewritten as absolute URLs.

// Exclude items if extraction fails
// ---------------------------------
// Excludes items from the resulting feed
// if we cannot extract any content from the
// item URL.
// Possible values...
// Enable: true
// Disable: false (default)
// User decides: 'user' (this option will appear on the form)
$options->exclude_items_on_fail = 'user';
// Enable single-page support
// -------------------------
// If enabled, we will try to follow single page links (e.g. print view) on multi-page articles.
// Currently this only happens for sites where single_page_link has been defined
// in a site config file.
$options->singlepage = true;

// Enable disk caching
// ----------------------

// Possible options:
// * Disable caching: false (default)
// * Enable caching: true
// Cache files are written to disk (in cache/ subfolders - which must be writable).
// Initially it's best to keep this disabled to make sure everything works
// as expected. If you have APC enabled, please also see smart_cache in the
// advanced section.

// Cache time (minutes)
// ----------------------
// How long should a response be cached?

// paid for by a corporation to promote their brand or product.
// Full-Text RSS can identify such articles in certain sites. If an article
// is identified as being a native ad, we'll add a <dc:type>Native Ad</dc:type>

/////////////////////////////////////////////////
// Enable XSS filter?
// ----------------------
// We have not enabled this by default because we assume the majority of
// our users do not display the HTML retrieved by Full-Text RSS
// in a web page without further processing. If you subscribe to our generated
// feeds in your news reader application, it should, if it's good software, already
// filter the resulting HTML for XSS attacks, making it redundant for
// Full-Text RSS do the same. Similarly with frameworks/CMS which display
// feed content - the content should be treated like any other user-submitted content.
//
// If you are writing an application yourself which is processing feeds generated by
// Full-Text RSS, you can either filter the HTML yourself to remove potential XSS attacks
// or enable this option. This might be useful if you are processing our generated
// feeds with JavaScript on the client side - although there's client side xss
// filtering available too, e.g. https://code.google.com/p/google-caja/wiki/JsHtmlSanitizer
//
// If enabled, we'll pass retrieved HTML content through htmLawed with
// safe flag on and style attributes denied, see
// http://www.bioinformatics.org/phplabware/internal_utilities/htmLawed/htmLawed_README.htm#s3.6
// Note: if enabled this will also remove certain elements you may want to preserve, such as iframes.
//
// Valid values:
// true - enabled, all content will be filtered
// 'user' (default) - user must pass &xss=1 in makefulltextfeed.php querystring to enable
// false - disabled
$options->xss_filter = 'user';
// Use effective URL in place of item URL
// ----------------------
// When we extract content for feed items, we often end up at a different URL than the
// one in the original feed. This is often a result of URL shorteners or
// tracking services being used by the feed publisher. We include the final
// (effective) URL we reached to get the content inside the dc:identifier field.
// If you enable this, we'll also use this URL in place of the original item URL
// in the new feed we produce.
// By default, we keep the original item URL but the user can request the effective
// URL by passing '&use_effective_url' in the querystring.
// Possible values:
// * Use effective URL: true
// * Keep item URL in original feed: false
// * Keep item URL unless user requests effective URL: 'user' (default)
$options->favour_effective_url = 'user';
// Favour item titles in feed
// ----------------------
// By default, when processing feeds, we assume item titles in the feed
// have not been truncated. So after processing web pages, the extracted titles
// are not used in the generated feed. If you prefer to have extracted titles in
// the feed you can either set this to false, in which case we will always favour
// extracted titles. Alternatively, if set to 'user' (default) we'll use the
// extracted title if you pass '&use_extracted_title' in the querystring.
// Possible values:
// * Favour feed titles: true
// * Favour extracted titles: false
// * Favour feed titles with user override: 'user' (default)
// Note: this has no effect when the input URL is to a web page - in these cases
// we always use the extracted title in the generated feed.
$options->favour_feed_titles = 'user';
// Allowed HTML parsers
// ----------------------
// Full-Text RSS will use HTML5PHP to parse HTML by default.
// On servers with Gumbo PHP extension, it will use that instead of HTML5PHP.
// (it's much faser, see our server initialisation script to set up a such a server).
// If HTML5 parsing is not required, you can request parsing with libxml:
// &parser=libxml
// The html5php parser is bundled with Full-Text RSS.
// see https://github.com/Masterminds/html5-php
//
// Note: html5php must appear in this list.

// Default parser
// --------------
// By default, Full-Text RSS will use Gumbo (a fast, C-based HTML5 parser)
// if it's availabe (requires Gumbo PHP extension).
// If it's not avilable, we'll automatically fall back to HTML5-PHP (also an HTML5
// parser, but written in PHP, so a little slower).
// To use Gumbo, you can run our server setup script on a new VPS instance.
// See http://help.fivefilters.org/customer/en/portal/articles/1143210-hosting
// The HTML5-PHP parser is bundled with Full-Text RSS, so available for all users.
// see https://github.com/Masterminds/html5-php
$options->default_parser = 'gumbo';
// Allow parser override
// ---------------------
// If enabled, user can pass &parser=html5php in the querystring to override the default parser.

// parser: html5php
// Possible values:
// * false: Don't allow overriding
// * true: Allow (default)

// Proxy server(s)
// ----------------------
// You can specify proxy servers here and ask Full-Text RSS to
// route HTTP requests through these servers.
// If no proxy server is listed, all requests will be made directly.
// A proxy server should be given a unique name (key in the array)
// and as its value another array with key 'host' and, if required, 'auth'.
//
// Note: if you're listing proxies so Full-Text RSS randomly chooses one
// for each request, you can also specify 'direct' as a value to make
// sure direct requests are randomly made as well.

// ----------------------
// How the proxy servers above should be used:
// Possible options:
// * Disable: false (no proxy will be used)
// * Named: specify which server should be used (e.g. 'example1')

// Note: if no proxy servers are entered in $options->proxy_servers, no proxies will be used.
$options->proxy = true;
// Proxy override in querystring
// ----------------------
// If enabled, user can disable or change the proxy server used.
// Possible values:
// * false: Don't allow override in querystring
// * true: Allow user to disable or choose a proxy through a request parameter, like so...
// &proxy=0 to disable
// &proxy=1 for default behaviour (see $options->proxy) (default)
// &proxy=example1 to specify one of the proxies listed in $options->proxy_servers
// Note: Only proxy servers listed in the config file can be used.

// Use APC user cache?
// ----------------------
// If enabled we will store site config files (when requested
// for the first time) in APC's user cache. Keys prefixed with 'sc.'
// This improves performance by reducing disk access.
// Note: this has no effect if APC is unavailable on your server.
$options->apc = true;
// Smart cache (experimental)
// ----------------------
// With this option enabled we will not cache to disk immediately.
// We will store the cache key in APC and if it's requested again
// we will cache results to disk. Keys prefixed with 'cache.'
// This improves performance by reducing disk access.
// Note: this has no effect if APC is disabled or unavailable on your server,
// or if you have caching disabled.

// URL Rewriting
// ----------------------
// Currently allows simple string replace of URLs.
// Useful for rewriting certain URLs to point to a single page
// or HTML view. Although using the single_page_link site config
// instruction is the preferred way to do this, sometimes, as
// with Google Docs URLs, it's not possible.
// Note: this might move to the site config file at some point.

// Content-Type exceptions
// -----------------------
// Here you can define different actions based
// on the Content-Type header returned by server.

// Cache directory level
// ----------------------
// Spread cache files over different directories (only used if caching is enabled).
// Used to prevent large number of files in one directory.
// This corresponds to Zend_Cache's hashed_directory_level
// see http://framework.zend.com/manual/en/zend.cache.backends.html
// It's best not to change this if you're unsure.
$options->cache_directory_level = 0;
// Cache cleanup
// -------------
// 0 = script will not clean cache (rename cachecleanup.php and use it for scheduled (e.g. cron) cache cleanup)
