Extension:TODOListProgressBar

What can this extension do?
This extension is aimed at making the process of tracking the progress of a TODO list (or other list) easier. When creating your TODO list, you include the tag along with each item. As you complete an item, you update its status accordingly and the rest of the extension takes care of displaying the nice progress bar for a visual indicator as to the progress of completing the TODO list. In addition, it places a status string where the tag is located so that your TODO list will tell you which items are complete and which arent.

Usage
If you do not want to keep referring to this page or the code, place a tag somewhere on a page and it will display the help contents for you. You can also see the same output here. Please note: The most current documentation will always be within the extension itself; it is highly recommended you use so you are sure the information you are given matches the version of TODO List Progress Bar you are running.

Help for TODO List Progress Bar

The tag has multiple modes of operation:


 * Defaults Mode (Not Implemented)
 * 
 * Sets defaults for the following items and progress bars such as color, width, height, etc.
 * Graphic Mode
 * Caption
 *  (No caption given)
 * Used for displaying a progress bar for a list.
 * Help Mode
 * Renders the help text you are reading at this moment.
 * Item Mode
 * Item
 * Item
 * Used for adding items to a list.
 * Progress Mode
 * Caption
 * 
 * Simple progress bar that isn't dependent upon a list.
 * Values Mode
 * 
 * Outputs list data in a table.
 * Outputs list data in a table.

All tags require the "type" parameter. It only has the following values:
 * "defaults" (Not Implemented)
 * "graphic"
 * "help"
 * "item"
 * "progress"
 * "values"

The type parameter tells the code what to do with the tag. As such, it has no default value.

TODO (pun)

 * 4) This will cause only a portion of the items value to be added to the final tally.
