-Twitter Friends Syncing
------------------------
+Twitter Bridge
+--------------
 
-As of Laconica 0.6.3, users may set a flag in their settings ("Subscribe
-to my Twitter friends here" under the Twitter tab) to have Laconica
-attempt to locate and subscribe to "friends" (people they "follow") on
-Twitter who also have accounts on your Laconica system, and who have
-previously set up a link for automatically posting notices to Twitter.
+* OAuth
 
-Optionally, there is a script (./scripts/synctwitterfriends.php), meant
-to be run periodically from a job scheduler (e.g.: cron under Unix), to
-look for new additions to users' friends lists. Note that the friends
-syncing only subscribes users to each other, it does not unsubscribe
-users when they stop following each other on Twitter.
+As of 0.8.1, OAuth is used to to access protected resources on Twitter
+instead of HTTP Basic Auth.  To use Twitter bridging you will need
+to register your instance of Laconica as an application on Twitter
+(http://twitter.com/apps), and update the following variables in your
+config.php with the consumer key and secret Twitter generates for you:
 
-Sample cron job:
+      $config['twitter']['consumer_key']    = 'YOURKEY';
+      $config['twitter']['consumer_secret'] = 'YOURSECRET';
 
-# Update Twitter friends subscriptions every half hour
-0,30 * * * * /path/to/php /path/to/laconica/scripts/synctwitterfriends.php>&/dev/null
+When registering your application with Twitter set the type to "Browser"
+and your Callback URL to:
+
+      http://example.org/mublog/twitter/authorization
+
+The default access type should be, "Read & Write".
+
+* Importing statuses from Twitter
+
+To allow your users to import their friends' Twitter statuses, you will
+need to enable the bidirectional Twitter bridge in config.php:
+
+      $config['twitterbridge']['enabled'] = true;
+
+and run the TwitterStatusFetcher daemon (scripts/twitterstatusfetcher.php).
+Additionally, you will want to set the integration source variable,
+which will keep notices posted to Twitter via Laconica from looping
+back.  The integration source should be set to the name of your
+application, exactly as you specified it on the settings page for your
+Laconica application on Twitter, e.g.:
+
+      $config['integration']['source'] = 'YourApp';
+
+* Twitter Friends Syncing
+
+Users may set a flag in their settings ("Subscribe to my Twitter friends
+here" under the Twitter tab) to have Laconica attempt to locate and
+subscribe to "friends" (people they "follow") on Twitter who also have
+accounts on your Laconica system, and who have previously set up a link
+for automatically posting notices to Twitter.
+
+As of 0.8.0, this is no longer accomplished via a cron job. Instead you
+must run the SyncTwitterFriends daemon (scripts/synctwitterfreinds.php).

+/**
+ * Data access interface
+ *
+ * This interface specifies data access methods libomb needs. It should be
+ * implemented by libomb users. OMB_Datastore is libomb’s main interface to the
+ * application’s data. Objects corresponding to this interface are used in
+ * OMB_Service_Provider and OMB_Service_Consumer.
+ *
+ * Note that it’s implemented as a class since OAuthDataStore is as well a
+ * class, though only declaring methods.
+ *
+ * OMB_Datastore extends OAuthDataStore with two OAuth-related methods for token
+ * revoking and authorizing and all OMB-related methods.
+ * Refer to OAuth.php for a complete specification of OAuth-related methods.
+ *
+ * It is the user’s duty to signal and handle errors. libomb does not check
+ * return values nor handle exceptions. It is suggested to use exceptions.
+ * Note that lookup_token and getProfile return null if the requested object
+ * is not available. This is NOT an error and should not raise an exception.
+ * Same applies for lookup_nonce which returns a boolean value. These methods
+ * may nevertheless throw an exception, for example in case of a storage errors.
+ *
+ * Most of the parameters passed to these methods are unescaped and unverified
+ * user input. Therefore they should be handled with extra care to avoid
+ * security problems like SQL injections.

+1.0.2
+-----
+* Fixed missing semicolon
+
+1.0.1
+-----
+* Fixed element creation (<ul> to <ul/> and <li> to </li>)
+* Fixed ac_even class (was ac_event)
+* Fixed bgiframe usage: now its really optional
+* Removed the blur-on-return workaround, added a less obtrusive one only for Opera
+* Fixed hold cursor keys: Opera needs keypress, everyone else keydown to scroll through result list when holding cursor key
+* Updated package to jQuery 1.2.5, removing dimensions
+* Fixed multiple-mustMatch: Remove only the last term when no match is found
+* Fixed multiple without mustMatch: Don't select the last active when no match is found (on tab/return)
+* Fixed multiple cursor position: Put cursor at end of input after selecting a value
+
+1.0
+---
+
+* First release.

+TODO
+
+- test formatItem implementation that returns (clickable) anchors
+- bug: handle del key; eg. type a letter, remove it using del, type same letter again: nothing happens
+- handle up/down keys in textarea (prevent default while select is open?)
+- docs: max:0 works, too, "removing" it(??)
+- fix ac_loading/options.loadingClass
+- support/enable request urls like foo/bar/10 instead of foo/q=10
+- urlencode request term before passing to $.ajax/data; evaluate why $.ajax doesn't handle that itself, if at all; try with umlauts, russian/danish/chinese characeters (see validate)
+- test what happens when an element gets focused programmatically (maybe even before then autcomplete is applied)
+- check if blur on selecting can be removed
+- fix keyhandling to ignore metakeys, eg. shift; especially important for chinese characters that need more then one key
+- enhance mustMatch: provide event/callback when a value gets deleted
+- handle tab key different then enter, eg. don't blur field or prevent default, just let it move on; in any case, no need to blur the field when selecting a value via tab, unlike return
+- prevent redundant requests on
+  - superstring returned no result, no need to query again for substring, eg. pete returned nothing, peter won't either
+  - previous query mustn't be requested again, eg. pete returns 10 lines, peter nothing, backspace to pete should get the 10 lines from cache (may need TimeToLive setting for cache to invalidate it)
+- incorporate improvements and suggestions by Hector: http://beta.winserver.com/public/test/MultiSuggestTest.wct
+- json support: An optional JSON format, that assumes a certain JSON format as default and just looks for a dataType "json" to be activated; [records], where each record is { id:String, label:String, moreOptionalValues... } 
+- accept callback as first argument to let users implement their own dynamic data (no caching) - consider async API
+- allow users to keep their incomplete value when pressing tab, just mimic the default-browser-autocomplete: tab doesn't select any proposed value -> tab closes the select and works normal otherwise
+- small bug in your autocomplete,  When setting autoFill:true I would expect formatResult to be called on autofill, it seems not to be the case.
+- add a callback to allow decoding the response
+- allow modification of not-last value in multiple-fields
+@option Number size Limit the number of items to show at once. Default: 
+@option Function parse - TEST AND DOCUMENT ME
+- add option to display selectbox on focus
+
+$input.bind("show", function() {
+	if ( !select.visible() ) {
+		onChange(0, true);
+	}
+});
+
+- reference: http://capxous.com/
+  - add "try ..." hints to demo
+  - check out demos
+- reference: http://createwebapp.com/demo/
+  
+- add option to hide selectbox when no match is found - see comment by Ian on plugin page (14. Juli 2007 04:31)
+- add example for reinitializing an autocomplete using unbind()
+
+- Add option to pass through additional arguments to $.ajax, like type to use POST instead of GET
+
+ - I found out that the problem with UTF-8 not being correctly sent can be solved on the server side by applying (PHP) rawurldecode() function, which decodes the Unicode characters sent by GET method and therefore URL-encoded.
+-> add that hint to docs and examples
+
+But I am trying this with these three values: “foo bar”, “foo foo”, and “foo far”, and if I enter “b” (or “ba”) nothing matches, if I enter “f” all three do match, and if I enter “fa” the last one matches.
+The problem seems to be that the cache is implemented with a first-character hashtable, so only after matching the first character, the latter ones are searched for.
+
+xml example:
+<script type="text/javascript">
+      function parseXML(data) {
+        var results = [];
+        var branches = $(data).find('item');
+        $(branches).each(function() {
+          var text = $.trim($(this).find('text').text());
+          var value = $.trim($(this).find('value').text());
+          //console.log(text);
+          //console.log(value);
+          results[results.length] = {'data': this, 'result': value, 'value': text};
+        });
+        $(results).each(function() {
+          //console.log('value', this.value);
+          //console.log('text', this.text);
+        });
+        //console.log(results);
+        return results;
+      };
+    $(YourOojHere).autocomplete(SERVER_AJAX_URL, {parse: parseXML});
+  </script>

+
+Hi all,
+
+I use Autocomplete 1.0 Alpha mostly for form inputs bound to foreign
+key columns. For instance I have a user_position table with two
+columns: user_id and position_id. On new appointment form I have two
+autocomplete text inputs with the following code:
+
+   <input type="text" id="user_id" class="ac_input"  tabindex="1" />
+   <input type="text" id="position_id" class="ac_input" tabindex="2" />
+
+As you can see the inputs do not have a name attribute, and when the
+form is submitted their values are not sent, which is all right since
+they will contain strings like:
+
+   'John Doe'
+   'Sales Manager'
+
+whereas our backend expects something like:
+
+   23
+   14
+
+which are the user_id for John Doe and position_id for Sales Manager.
+To send these values I have two hidden inputs in the form like this:
+
+   <input type="hidden" name="user_id" value="">
+   <input type="hidden" name="position_id" value="">
+
+Also I have the following code in the $().ready function:
+
+   $("#user_id").result(function(event, data, formatted) {
+     $("input[@name=user_id]").val(data[1]);
+   });
+   $("#position_id").result(function(event, data, formatted) {
+     $("input[@name=position_id]").val(data[1]);
+   });
+
+As could be seen these functions stuff user_id and position_id values
+(in our example 23 and 14) into the hidden inputs, and when the form
+is submitted these values are sent:
+
+   user_id = 23
+   position_id = 14
+
+The backend script then takes care of adding a record to our
+user_position table containing those values.
+
+I wonder how could the plugin code be modified to simplify the setup
+by taking care of adding hidden inputs and updating the value of
+hidden inputs as default behavior. I have successfully attempted a
+simpler solution - writing a wrapper to perform these additional tasks
+and invoke autocomplete as well. I hope my intention is clear enough,
+if not, this is exactly the expected outcome:
+
+Before:
+
+   <script type="text/javascript"
+   src="jquery.autocomplete-modified.js"></script>
+   <input type="text" name="user_id" class="ac_input" tabindex="1" />
+
+After:
+
+   <input type="text" id="user_id" class="ac_input" tabindex="1" />
+   <input type="hidden" name="user_id" value="23">
+
+
+Last word, I know this looks like a tall order, and I do not hope
+someone will make a complete working mod for me, but rather would very
+much appreciate helpful  advise and directions.
+
+Many thanks in advance
+Majid

+Infinite Scroll adds the following functionality to your Laconica installation: When a user scrolls towards the bottom of the page, the next page of notices is automatically retrieved and appended. This means they never need to click "Next Page", which dramatically increases stickiness.
+
+Installation
+============
+Add "addPlugin('InfiniteScroll');" to the bottom of your config.php
+That's it!
