Bookmark Manager
An integrated bookmark manager in the spirit of de.lirio.us. Note: de.lirio.us will be shutting down within the month (end of July 2006), so if you plan on exporting your de.lirio.us bookmarks, better do it soon!Try it out! Beta version with latest code here.
then go to a webpage and click on the bookmark you just saved.
- If you want to test bookmarklets, copy and paste this as a bookmark:
javascript:location.href='http://durango.dcccd.edu/wikitest/wikka.php?wakka=Bookmarks&action=add&uri='+escape(location.href)+'&title='+encodeURIComponent(document.title)+'&wikka_bookmarklet=1'
then go to a webpage and click on the bookmark you just saved.

Add bookmark page
Design ideas
- Allow both user-specific and site-wide bookmark access (other than those tagged as "private")
- Allow tagging of objects other than URIs (such as pages)
- Implement as both a handler and an action
- Gordon Luk (creator of Freetag, the engine behind Bookmark Manager) has some interesting comments about tagging here.
- Here's another Wikka tagging project using the Freetag engine. It would be useful to investigate the merging of that project with this one to permit page tagging in addition to bookmark tagging.
Progress reports
- Beta test announcement: Well, after hacking around with Scuttle, I decided it was much too complex for what I had in mind. Nils suggested another project, Freetag, that seems to provide the basic functionality needed without all of the formatting/presentation overhead. I have a beta up and running here, and would appreciate your comments and suggestions! Keep in mind this is still quite rough around the edges, but I was aiming more towards proof-of-concept. I think something like this would be a cool addition (as a 100% modular plugin) to Wikka...
- Progress is going well. Add/edit/delete capabilities have been added. Two Perl scripts (see below) have been provided that allow you to export your bookmarks from de.lirio.us and import them into BookmarkManager. Beta currently running under Wikka 1.1.6.2-alpha. A page of 25 links (out of 200+) and about 100 tags renders in approximately 1.1 seconds.
- More enhancements and modifications: Numeric tags, link pagination, tag pagination, tag/link editing and deletion.
- More cool stuff: Support for bookmarklets (small Javascript bookmark that immediately saves the page you are viewing and returns to the page), tag links within link descriptors, better use of screen real estate using CSS.
TODO
Indicates issues that have been addressed- This code is most likely not yet safe for a production environment! I've worked to secure all data passed in from GET/POST requests, as well as from Wikka itself in some cases. I'm hoping a few more folks have time to look over the code for any obvious security weaknesses.
- User tags should be displayed as raw tags.
- As a general consideration it would be nice to provide this functionality as a handler.
- it would be nice to have a link for the add-form near list yours.
- how about something like my tags / all tags? List all/list yours now provides this functionality
- what would be usefull: If I tag a link with the name of an existing wiki-page, this link could show up at the end of the page.
- Need to fix logic so "your" tags only display "your" links (also, identify tag cloud as "all" or "yours")
- Optional logic to display tags in a right-justified vertical list instead of a cloud
- Paging, user prefs
- Tag pages as well as links
- Please put the wikka_freetag class in a file like Wikka.freetag.class.php in the new \libs directory.
- $freetag_options -> why not use the params provided by wikka ($this->mysql_host, etc.)?
- Create bookmarklets such as these (borrowed from de.lirio.us): Implemented...see below for details
- Provide edit/delete functionality
- Search functionality
- Restricting spam. Some ideas: Option to allow only registered users to set bookmarks Implemented; using "captcha" images to preclude automated scripts
- It would be nice if tags in each bookmarks were links pointing to the list of bookmarks with the same tag.
- Fix PHP warnings w/r/t/ null arrays in ksort, min, max, etc.
Installation
- Install a copy of Freetag in 3rdparty/plugins Check for freetag class and helper libraries

- In order to use the stylesheet, add the following lines to the files indicated (click [[http://wush.net/trac/wikka/ticket/246 here]] for a justification as to why these changes are necessary to the core):
**wikka.config.php:**
%%(php)
'additional_stylesheets' => 'bookmarkmgr.css',
%%
**actions/header.php:**
%%(php)
// Locate this line...
" />
// ...and add the following codeblock:

$sheets = preg_split("/[\s]+/", $this->GetConfigValue("additional_stylesheets"));
foreach($sheets as $sheet) {
echo "\n";
}
}
