Yet another memex approximation: a Chrome extension for making paths of annotations through web pages.

branch: master
README.md

yamemex provides a little margin for Chromium (or Google Chrome) in which you can jot notes about the web page you’re reading. It’s an annotation-centered take on bookmarking. This version is very preliminary, but it already provides a reverse-chronological view of your bookmark annotations, and supports Twitter-style #hashtags to categorize them.

It’s free software under the MIT X11 License.

To install

At some point soon, I’ll put up .crx files that you can download and install with just a click. It's not quite ready for that, though.

  1. Put this source directory somewhere, like /home/bob/yamemex. (You can download it from Github with git clone git://github.com/kragen/yamemex.git.)
  2. Load the submodules: cd yamemex; git submodule init; git submodule update.
  3. In Chromium, from the menu, pick Tools → Extensions.
  4. On the Extensions page, if necessary, click the [+] next to Developer Mode to enable Developer Mode.
  5. Click the [ Load unpacked extension... ] button on the left side of the Extensions page.
  6. Pick the directory containing this README file.

You should see the yamemex icon appear to the left of the wrench icon that opens Chrome’s menu.

DONE

  • saving annotations for bookmarked pages with a resizable annotation popup in-page
  • reverse-chronological view in browser
  • icon on page to indicate that there are annotations
  • add installation instructions
  • add license
  • focusing annotation popup when it opens
  • auto-selecting placeholder text so you can just start typing instead of working to delete the placeholder text for a new annotation
  • saving page titles
  • make blog view run a little bit faster
  • running when page starts loading, rather than when it finishes loading
  • adding date headers to the reverse-chronological view
  • a “public” checkbox to allow private annotations
  • giving blog view a stylesheet to make it look good
  • dismissing annotation popup
  • tagging: Twitter-like, #hashtags in the blog view are links to filtered views that show only things tagged with that hashtag.
  • smoothly animating open annotation popup
  • making browser-action icon open blog view when on a new-tab page

BUGS

  • hits disk after every keystroke in the annotation window
  • malicious JavaScript in a web page can spy on your annotation
  • annotation button doesn’t work until page finishes loading
  • doesn’t work on framesets

TODO (possibly)

  • make annotation popup close button use some clip art from openclipart
  • add clickable recent tags in annotation popup
  • make blog view editable (!!)
  • refactor this database stuff, because this is totally fucking ridiculous. Adding the “public” checkbox involved editing seven places:

    1. db.js, to add the column and an index on it;
    2. setAnnotation in yamemex.html, to copy it from the request into the database;
    3. the getAnnotationsFor handler in yamemex.html, to copy it from the database into a request (already fixed);
    4. the global variables in ymcontent.js, to have a place to store it in the page;
    5. the handler for the getAnnotationsFor response in ymcontent, to copy it from the response into those variables;
    6. openAnnotationWindow in ymcontent, to add the HTML and copy from the variable into the HTML state;
    7. sendAnnotation in ymcontent, to copy from the global variable to the updateAnnotationsFor request;
    8. sendAnnotation in ymcontent, to copy from the HTML back into the object.

      Fixing this should involve the following steps:

    • put ourAnnotation and ourPublic into one object, eliminating #4.
    • put the URL and title in there too
    • change the request sent to the background page to just have that object (the one to insert into the database), eliminating #7.
    • changing the database code to insert arbitrary random properties on the object it’s handed instead of a fixed set of properties, eliminating #2.
    • changing the getAnnotationsFor handler to send an object containing all columns of the row, eliminating #5.

      This would leave only duplications #1, #6, and #8. Unifying #6 and #8 would involve a simple model-view framework, and unifying #1 with them would involve a Django-style schema definition EDSL in JS, so I don’t feel as bad about those.

  • avoid empty-string unclickable titles in blog view (oh shit. the title in the database for this one is ‘{{ mustache }}’. I think that means mustache.js is fucking with me and double-interpreting the fucking variable.) I'm pretty sure this is a bug because it doesn’t seem to be documented and it isn't represented in the examples directory used for unit tests. Minimal reproduction:

      Mustache.to_html('{{b}}', {b: '{{c}x}' }) -> '{{c}x}'
      Mustache.to_html('{{#a}}{{b}}{{/a}}', {a: [{b: '{{c}x}' }]}) -> '{{c}x}'
      Mustache.to_html('{{b}}', {b: '{{c}}' }) -> '{{c}}'
      Mustache.to_html('{{#a}}{{b}}{{/a}}', {a: [{b: '{{c}}' }]}) -> '' (wrong)
    

    Looks like the problem in Mustache.js is that it re-interprets the HTML coming out of the inner section as a template:

      var html = this.render_section(template, context, partials);
      if(in_recursion) {
        return this.render_tags(html, context, partials, in_recursion);
      }
    
      this.render_tags(html, context, partials, in_recursion);
    
  • make titles editable in annotation popup

  • stop “Type your annotations here.” annotations from being added when you alt-tab away from an unwanted annotation window. This will be a lot easier when we can just copy the object being edited and then see if anything about it has changed, and not send a message if not.
  • automatically snarf publication date off the page
  • storing original date for annotations so they stay in order (perhaps linked from latest date)
  • make annotation pane not fade when keyboard focus is in it
    • refactor this into the first version of Kogluktualuk
  • growing annotation popup taller as you type text into it
  • hiding annotations from the page in an iframe
  • handling URL changes that don’t reload the page
  • centering “see all” link
  • saving favicons
  • saving screenshots
  • archiving page contents
  • Markdown or similar formatting for annotations. https://github.com/fivesixty/mdext looks like the current home page of the most-maintained version of Showdown, which seems like the best implementation of Markdown in JS. There’s a WYSIWYM editor for it at http://code.google.com/p/wmd-new/.
  • publishing your bookmarks as a blog on the web
  • saving previous versions of annotations
  • syncing across multiple browsers
  • saving highlighted quotations from pages
  • automatically parsing dates from pages and displaying bookmarks in a calendar view
  • Lotus-Agenda-like auto-tagging based on user-specified keywords
  • plugins to seek bibliographic data and enable bookmarking of it
  • “friends”
  • subscribing to friends’ annotations
  • “like” button on friends’ annotations
  • Wiki-like editing of friends’ annotations
  • real-time updates
  • comment threads on annotations
  • Agenda-like grid views
  • full-text search
  • blog pagination
  • backends for:
  • contextual tags (what was this?)
