* Name: Ouroboros API
|
||||
* Author: Diftraku <diftraku[at]derpy.me>
|
||||
* Description: Ouroboros-like API for Shimmie
|
||||
* Documentation:
|
||||
* Currently working features
|
||||
* <ul>
|
||||
* <li>Post:
|
||||
* <ul>
|
||||
* <li>Index/List</li>
|
||||
* <li>Show</li>
|
||||
* </ul>
|
||||

* <ul>
|
||||
* <li>Index/List</li>
|
||||
* </ul>
|
||||
* </li>
|
||||
* </ul>
|
||||
* Tested to work with CartonBox using "Danbooru 1.18.x" as site type.
|
||||
* Does not work with Andbooru or Danbooru Gallery for reasons beyond me, took me a while to figure rating "u" is bad...
|
||||
* Lots of Ouroboros/Danbooru specific values use their defaults (or what I gathered them to be default)
|
||||
* and tons of stuff not supported directly in Shimmie is botched to work
