/*
Name: Danbooru Client API for Shimmie2
Description: Provides simple interfaces for third party software to interact with Shimmie via
simple HTTP GET/POST requests.
Author: JJS <jsutinen@gmail.com>
Notes:
danbooru API based on documentation from danbooru 1.0 - http://attachr.com/7569
I've only been able to test add_post and find_tags because I use the old danbooru firefox extension for firefox 1.5
Functions currently implemented:
add_comment - NOT DONE YET, waiting on some backend shimmie code :)
add_post - title and rating are currently ignored because shimmie does not support them
find_posts - sort of works, filename is returned as the original filename and probably won't help when it comes to actually downloading it
find_tags - id, name, and after_id all work but the tags parameter is ignored just like danbooru 1.0 ignores it
CHANGELOG
21-OCT-07 9:07PM CST - JJS
Turns out I actually did need to implement the new parameter names
for danbooru api v1.8.1. Now danbooruup should work when used with /api/danbooru/post/create.xml
Also correctly redirects the url provided by danbooruup in the event
of a duplicate image.
19-OCT-07 4:46PM CST - JJS
Add compatibility with danbooru api v1.8.1 style urls
for find_posts and add_post. NOTE: This does not implement
the changes to the parameter names, it is simply a
workaround for the latest danbooruup firefox extension.
Completely compatibility will probably involve a rewrite with a different URL

Notes
* The only necessary parameter is tags and either file or source.
* If you want to sign your post, you need a way to authenticate your account, either by supplying login and password, or by supplying a cookie.
* If an account is not supplied or if it doesn‘t authenticate, he post will be added anonymously.
* If the md5 parameter is supplied and does not match the hash of what‘s on the server, the post is rejected.
Response
The response depends on the method used:
Post
* X-Danbooru-Location set to the URL for newly uploaded post.
Get
* Redirected to the newly uploaded post.

Link to Image adds BBCode and HTML link codes to the image view. Offers code for a customizable text link, thumbnail links, and full image inline.
Author: Erik Youngren <artanis.00@gmail.com>
License: GPLv2
Submit a Bug Report or Suggestion for Link to Image:
* http://trac.shishnet.org/shimmie2/newticket?owner=artanis.00@gmail.com&component=third%20party%20extensions&keywords=link_to_image
= Use =
There is one option in Board Config: Text Link Format.
It takes the following arguments as well as plain text.
|| arguments || replacement ||
|| $id || The image ID. ||
|| $hash || The MD5 hash of the image. ||
|| $tags || The image's tag list. ||
|| $base || The base HREF as set in Config. ||
|| $ext || The image's extension. ||
|| $size || The image's display size. ||
|| $filesize || The image's size in KB. ||
|| $filename || The image's original filename. ||
|| $title || The site title as set in Config. ||
Link to Image will default this option to '$title - $id ($ext $size $filesize)'.
To reset to the default, simply clear the current setting. Link to Image will then fill in the default value after the save.
To leave the setting blank for any reason, leave a space (' ') in it.
= Install =
1. Copy the folder {{{contrib/link_image/}}} to {{{ext/}}}.
2. In the Config panel, make sure Base URL is set (you may as well set Data URL while you're there, if you haven't already.)
3. Make sure Image Link, Thumb Link, and Short Link all contain the full path ("http://" and onward,) either by using $base or plain text. Link to Image will not be able to retrieve the correct paths without these variables.
= Change Log =
== Version 0.3.0 ==
* Moved Link to Image over to the official theme engine. This functions basically the same as what the prototype was, but it's more thought out and nicer.
* Cleaned up the insides a bit.
== Version 0.2.0 ==
* Changed the HTML generation to use a prototype theme engine. All HTML generation is now contained within {{{link_image.html.php}}}, which may be copied to the current theme folder and edited from there.
== Version 0.1.4 - 20070510 ==
* Style changes.
* Added output containing only the locations of the thumb, image and post.
* Added a link to wikipedia's HTML page, just as BBCode has a wikipedia link.
== Version 0.1.3b - 20070509 ==
* Renamed style.css to _style.css to avoid the auto loader.
== Version 0.1.3 - 20070508 ==
* Created Readme.txt
* Merged 0.1.2 into 0.1.2b
* Removed uneeded documentation from main.php
* Rewrote the css to be unique. Previously used CSS I wrote for elsewhere. Styled to reduce space consumption.
* Added code to insert the CSS import.
* Updated Nice URLs to allow access to the /ext/ folder. (Why is my stylesheet returning HTML instead of CSS?)
* First SVN update.
== Version 0.1.2b - 20070507 ==
(fairly simultaneous with 0.1.2)
* shish:
* Updated to new extension format
* Created folder link_image in trunk/contrib
* Renamed link_image.ext.php to main.php and moved to /link_image/
* Created style.css {{{ /* 404'd :|*/ }}}.
* Documentation (different from mine.)
* Changed add_text_option() and added add_label() in SetupBuildingEvent because I was using an edited version of the function that shish didn't know about. It was a wonder that didn't throw massive errors.
* Published on SVN.
== Version 0.1.2 - 20070506 ==
* Textboxes now select-all when they gain focus.
* Commenting and documentation.
== Version 0.1.1 - 20070506 ==
* Fixed HTML thumbnail link code. (image tag was being html_escaped twice, resulting in "$gt;" and "&lt;" from the first escape becoming "&amp;gt;" and "&amp;lt;") It turns out that html_escape was completely unnecessary, all I had to do was replace the single-quotes around the attributes with escaped double-quotes ('\"'.)
== Version 0.1.0 - 20070506 ==
* Release.
