/**
 * title: database
 * description: basic db() interface for parameterized SQL and result folding
 * api: php
 * type: database
 * version: 0.7
 * depends: pdo
 * license: Public Domain
 * author: Mario Salzer
 * url: http://php7framework.sourceforge.net/
 *
 *
 * QUERY
 *
 * Provides simple database queries with enumerated or named parameters. It's
 * flexible in accepting scalar arguments and arrays. Array args get merged,
 * or transcribed when special placeholders are present:
 *
 *   $r = db("SELECT * FROM tbl WHERE a>=? AND b IN (??)", $a, array($b));
 *
 * Two ?? are used for interpolating arrays, which is useful for IN clauses.
 * The placeholder :? interpolates key names (doesn't add values).
 * And :& or :, or :| become a name=:assign list grouped by AND, comma, OR.
 * Whereas :: turns into a simple :named,:value,:list (for IN clauses).
 * Also configurable {TOKENS} are replaced automatically (db()->tokens[]).
 *
 * RESULT
 *
 * The returned result can be accessed as single data row, with $data->column
 * or using $data["column"].
 * Or if it's a result list, foreach() can iterate over all returned rows.
 * And all PDO ->fetch() methods are still available for use on the result obj.
 * ArrayObjects cannot be used like real arrays in all contexts; typecasting
 * the data out is not possible, in string context curly braces "{$a->x}" are
 * necessary, and in sub-loops needed object syntax "foreach ($a->subarray as)"
 *
 * CONNECT  
 *
 * The db() interface utilizes the global "$db" variable. Which could also be
 * instantiated separately or using:
 * db("connect", array("mysql:host=localhost;dbname=test","username","password"));
 *
 * RECORD WRAPPER
 *
 * There's also a simple table data gateway wrapper implemented here. It
 * accepts db() queries for single entries, and allows ->save()ing back, or
 * to ->delete() records.
 * You should only use it in conjuction with sql2php and its simpler wrappers.
 *

 /**
  * api: php
  * title: Input $_REQUEST wrappers
  * type: interface
  * description: Encapsulates input variable superglobals for easy sanitization access
  * version: 2.7
  * revision: $Id$
  * license: Public Domain
  * depends: php:filter, php >5.0, html_purifier
  * config: <const name="INPUT_DIRECT" type="multi" value="disallow" multi="disallow|raw|log" description="filter method for direct $_REQUEST[var] access" />
  *         <const name="INPUT_QUIET" type="bool" value="0" multi="0=report all|1=no notices|2=no warnings" description="suppress access and behaviour notices" />
  * throws: E_USER_NOTICE, E_USER_WARNING, OutOfBoundsException
  *
  * Using these object wrappers ensures a single entry point and verification
  * spot for all user data. They wrap all superglobals and filter HTTP input
  * through sanitizing methods. For auditing casual and unverified access.
  *
  * Standardly they wrap: $_REQUEST, $_GET, $_POST, $_SERVER, $_COOKIE
  * And provide convenient access to filtered data:
  *   $_GET->int("page_num")                      // method
  *   $_POST->text["commentfield"]                // array syntax
  *   $_REQUEST->text->ascii->strtolower["xyz"]   // filter chains
  *
  * Available filter methods are:
  *   ->int
  *   ->float
  *   ->boolean
  *   ->name
  *   ->id
  *   ->words
  *   ->text
  *   ->ascii
  *   ->nocontrol
  *   ->spaces
  *   ->q
  *   ->escape
  *   ->regex
  *   ->in_array
  *   ->html
  *   ->purify
  *   ->json
  *   ->length
  *   ->range
  *   ->default
  * And most useful methods of the php filter extension.
  *   ->email
  *   ->url ->uri ->http
  *   ->ip
  *   ->ipv4->public
  * PHP string modification functions:
  *   ->urlencode
  *   ->strip_tags
  *   ->htmlentities
  *   ->strtolower
  * Automatic filter chain handler:
  *   ->array
  * Fetch multiple variables at once:
  *   ->list["var1,key,name"]
  * Process multiple entries as array:
  *   ->multi->http_build_query["id,token"]
  * Possible but should be used very consciously:
  *   ->xss
  *   ->sql
  *   ->mysql
  *   ->log
  *   ->raw
  *
  * You can also pre-define a standard filter-chain for all following calls:
  *   $_GET->nocontrol->iconv->utf7->xss->always();
  *
  * Using $__rules[] a set of filter rules can be preset per variable name.
  *
  * Parameterized filters can alternatively use the ellipsis … symbol (AltGr+:)
  * instead of the terminating method access syntax.
  *   $_GET->int->range…0…59["minutes"]
  *
  * Some filters are a mixture of sanitizing and validation. Basically
  * all can also be used independently of the superglobals with their
  * underscore name, $str = input::_text($str);
  *
  * For the superglobals it's also possible to count($_GET); or check with
  * just $_POST() if there are contents. (Use this in lieu of empty() test.)
  * There are also the three functions ->has ->no ->keys() for array lookup.
  *
  * Defining new filters can be done as methods, or since those are picked
  * up too, as plain global functions. It's also possible to assign function
  * aliases or attach closures:
  *   $_POST->_newfilter = function($s) { return modified($s); }
  * Note that the assigned filter name must have an underscore prefixed.
  *
  * --
  *
  * Input validation of course is no substitute for secure application logic,
  * parameterized sql and proper output encoding. But this methodology is a
  * good base and streamlines input data handling.
  *
  * Filter methods can be bypassed in any number of ways. There's no effort
  * made at prevention here. But it's recommended to simply use ->raw() when
  * needed - not all input can be filtered anyway. This way an audit handler
  * could always attach there - when desired.
  *
  * The goal is not to coerce, but encourage security via API *simplicity*.

<?php
/**
 * This class provides a simple interface for OpenID (1.1 and 2.0) authentication.
 * Supports Yadis discovery.
 * The authentication process is stateless/dumb.
 *
 * Usage:
 * Sign-on with OpenID is a two step process:
 * Step one is authentication with the provider:
 * <code>
 * $openid = new LightOpenID('my-host.example.org');
 * $openid->identity = 'ID supplied by user';
 * header('Location: ' . $openid->authUrl());
 * </code>
 * The provider then sends various parameters via GET, one of them is openid_mode.
 * Step two is verification:
 * <code>
 * $openid = new LightOpenID('my-host.example.org');
 * if ($openid->mode) {
 *     echo $openid->validate() ? 'Logged in.' : 'Failed';
 * }
 * </code>
 *
 * Change the 'my-host.example.org' to your domain name. Do NOT use $_SERVER['HTTP_HOST']
 * for that, unless you know what you are doing.
 *
 * Optionally, you can set $returnUrl and $realm (or $trustRoot, which is an alias).
 * The default values for those are:
 * $openid->realm     = (!empty($_SERVER['HTTPS']) ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'];
 * $openid->returnUrl = $openid->realm . $_SERVER['REQUEST_URI'];
 * If you don't know their meaning, refer to any openid tutorial, or specification. Or just guess.
 *
 * AX and SREG extensions are supported.
 * To use them, specify $openid->required and/or $openid->optional before calling $openid->authUrl().
 * These are arrays, with values being AX schema paths (the 'path' part of the URL).
 * For example:
 *   $openid->required = array('namePerson/friendly', 'contact/email');
 *   $openid->optional = array('namePerson/first');
 * If the server supports only SREG or OpenID 1.1, these are automaticaly
 * mapped to SREG names, so that user doesn't have to know anything about the server.
 *
 * To get the values, use $openid->getAttributes().
 *
 *
 * The library requires PHP >= 5.1.2 with curl or http/https stream wrappers enabled.

            <a href="http://freecode.club/">freecode.club</a> and
            <a href="http://freshmeat.club/">freshmeat.club</a> are supposed to become
            FM/FC substitutes with differing views on shared data sets.

       <li> <a href="http://directory.fsf.org/">http://directory.fsf.org/</a>
              - Free Software directory
              
       <li> http://www.ohloh.net/
              - Statistically tracks open source project development.

       <li> http://sourceforge.net/ - The original open source development plattform
            is still home to and primary notification hub for many projects.

       <li> http://github.com/ - Is a frontend onto a distributed version control
            system. It's less suited for end users, but still allows searching for
            software.

       <li> http://savannah.nongnu.org/ - Provides an alternative Free software
            development plattform.

       <li> https://launchpad.net/ - Is the development hub for Ubuntu and also
            lists a few things that haven't made it into the package managers yet.

       <li> http://www.opensourcesoftwaredirectory.com/
              - Lists only stable and well-known Linux software, as it's intended
                for end users.
              
       <li> http://www.linuxalt.com/
              - Curates a list of Linux software alternatives for migrating newcomers.

       <li> <a href="http://www.libe.net/version/index.php">Libe.net</a>
              - Linux and open source software archive

       <li> And, of course, WP as always provides a few open source listings
            as well: http://en.wikipedia.org/wiki/List_of_free_and_open-source_software_packages
        
   </ul>
   </p>


   <h2>Script directories, mixed open source/commercial listing</h2>
   <p>
       The following listing directories contain web software. For the largest
       part their code is super ancient, and there are lots of non-free listings.
   </p>
   <p>
   <ul>
       <li> http://www.hotscripts.com/
       <li> http://www.devscripts.com/
       <li> http://www.developertutorials.com/scripts/
       <li> http://www.bigresource.com/scripts/

       <li> http://www.needscripts.com/
       <li> http://www.advancescripts.com/

   </ul>
   </p>


   <h2>Paid-for listings</h2>
   <ul>
       <li> http://osliving.com/ - Kinda odd, seems to thrive on click thru
       ads and is primarily about receiving donations for FLOSS listings.

   </ul>

           You can always edit the common project information together with
           a current release.  It will show up on the frontpage whenever you

        <h3>Automatic Release Tracking</h3>
        <p>
           <em>You can skip this section.</em>
           But instead of registering each version manually, you can later automate the process
           with some version control systems or e.g. your project homepage and changelog.
