NotAlways right found it necessary to remove their RSS feeds recently. This is a *simple* bridge to grab the ones on the front page. It allows you to filter the articles based on their classification (right, working, romantic, related, learning, friendly, hopeless, unfiltered, or all).
The limit was used to specify the number of pages to return from a given
topic which resulted in the number of returned items variing between one
and however many entries are listed on one page.
This commit changes the implementation for the limit to keep loading more
pages until the specified limit is reached. Excessive elements are removed
in order to return the exact amount of items specified by the limit.
This behavior is closer to how other bridges are implemented and makes it
more natural to use without being too confusing. Existing queries must be
updated to account for the new limit.

cURL is a powerful library specifically designed to connect to many
different types of servers with different types of protocols. For
more detailed information refer to the PHP cURL manual:
- http://php.net/manual/en/book.curl.php
Due to this change some parameters for the getContents function were
necessary (also applies to getSimpleHTMLDOM and getSimpleHTMLDOMCached):
> $use_include_path removed
This parameter has never been used and doesn't even make sense in
this context; If set to true file_get_contents would also search
for files in the include_path (specified in php.ini).
> $context replaced by $header and $opts
The $context parameter allowed for customization of the request in
order to change how file_get_contents would acquire the data (i.e.
using POST instead of GET, sending custom header, etc...)
cURL also provides facilities to specify custom headers and change
how it communicates to severs. cURL, however, is much more advanced.
- $header is an optional parameter (empty by default). It receives
an array of strings to send in the HTTP request header.
See 'CURLOPT_HTTPHEADER':
"An array of HTTP header fields to set, in the format
array('Content-type: text/plain', 'Content-length: 100')"
- php.net/manual/en/function.curl-setopt.php
- $opts is an optional parameter (empty by default). It receives
an array of options, where each option is a key-value-pair of
a cURL option (CURLOPT_*) and it's associated parameter. This
parameter accepts any of the CURLOPT_* settings.
Example (sending POST instead of GET):
$opts = array(
CURLOPT_POST => 1,
CURLOPT_POSTFIELDS => '&action=none'
);
$html = getContents($url, array(), $opts);
Refer to the cURL setopt manual for more information:
- php.net/manual/en/function.curl-setopt.php
> $offset and $maxlen removed
These options were supported by file_get_contents, but there doesn't
seem to be an equivalent in cURL. Since no caller uses them they are
safe to remove.
Compressed data / Encoding
By using cURL instead of file_get_contents RSS-Bridge no longer has
to handle compressed data manually.
See 'CURLOPT_ENCODING':
"[...] Supported encodings are "identity", "deflate", and "gzip".
If an empty string, "", is set, a header containing all supported
encoding types is sent."
- http://php.net/manual/en/function.curl-setopt.php
Notice: By default all encoding types are accepted (""). This can
be changed by setting a custom option via $opts.
Example:
$opts = array(CURLOPT_ENCODING => 'gzip');
$html = getContents($url, array(), $opts);
Proxy
The proxy implementation should still work, but there doesn't seem
to be an equivalent for 'request_fulluri = true'. To my understanding
this isn't an issue because cURL knows how to handle proxy communication.
Requesting a username with a leading slash would cause error 500
because the requested URI would contain two slashes in a row.
For example username "/test" would result in:
https://facebook.com//test

* [BridgeAbstract] Implement customizable cache timeout
The customizable cache timeout is used instead of the default cache
timeout (CACHE_TIMEOUT) if specified by the caller.
* [index] Add new global parameter '_cache_timeout'
The _cache_timeout parameter is an optional parameter that can be
used to specify a custom cache timeout. This option is enabled by
default.
It can be disabled using the named constant 'CUSTOM_CACHE_TIMEOUT'
which supports two states:
> true: Enabled (default)
> false: Disabled
* [BridgeAbstract] Change scope of 'getCacheTimeout' to public
* [html] Add cache timeout parameter to all bridges
The timeout parameter only shows if CUSTOM_CACHE_TIMEOUT has been set
to true. The default value is automatically set to the value specified
in the bridge.
* [index] Disable custom cache timeout by default
The mbstring extension is required by all formats in order to convert multi-
byte characters to UTF-8. This commit adds an extension check to throw an
error message if the extension is not enabled.
The author name is parsed by searching a string within the entire
HTML document:
$author = $html->innertext;
$author = substr($author, strpos($author, '"author=') + 8);
$author = substr($author, 0, strpos($author, '\u0026'));
This solution will return big portions of the HTML document if
the strpos function returns zero (not found).
This commit replaces the previous implementation by searching for
a specific script tag and making use of the JSON data inside it.

This bridge returns feeds for any URI that is compatible with the
IPB implementation (currently 4.x). Older versions might work, but
there is no guarantee.
Only forum and topic URIs are supported!
The bridge automatically checks if natural feeds are available (by
adding '.xml' to the URI). If so the feed is returned. Otherwise
the bridge will attempt to identify the content type and build a
feed accordingly.
Valid URIs are forums and topics. For forums the first page is
returned, for topics the last one. Elements are ordered such that
the latest entry is returned first (oldest-to-newest)
The optional parameter '&limit=' specifies how many pages should
be loaded (default: 1). Topics are loaded in reverse order.
=> Does not work with forums!
Images are provided as enclosures and scaled to a max-size of
400x400 pixels by default (Except for natural feeds).
The content is filtered before being returned:
- Unnecessary tags are removed (iframes, etc...)
- Styles for blockquotes are restored (grey background)
Closes#507
