// "@Oprium"  - version 1.1

// This bookmarklet lets you select and share content on Oprium.com
// You can modify it for your own Discourse forum as you wish. Vivat FOSS :)

// Currently uses the code of Bullseye+jQery, Upndown and Rawgit.com as a CDN.

// "Upndown" (~129kb) converts HTML to MD - https://github.com/netgusto/upndown  
// Ditched "To-Markdown" (~9kb, but has many issues) - https://github.com/domchristie/to-markdown

// Creates a new topic on a discourse forum via URL:
// http://your.forum/new-topic? title=DOCUMENT_TITLE_TEXT
// &body=MARKDOWN_TEXT &category=category/subcategory &tags=keyword1,keyword2
//
// See: https://meta.discourse.org/t/compose-a-new-pre-filled-topic-via-url/28074

// Bullseye (original code) - https://gist.github.com/ttscoff/6109434
// version 0.3 - Add "Escape" key to cancel 
// Only use the first class when constructing path, potentially avoid dynamically-added classnames 
// Call the bookmarklet with "window.bullseyeShowFrame=0" at the beginning to return just raw text.
//
// version 0.2 - Resolves relative urls, removes Twitter intent links, tries to update lazy loaded
// image urls, loads from raw source, with fallback for dynamically-loaded content.
// -------------------------------------------------------------------------------------------
// TODO: Get the 'meta keywords' from a page and send them as 'tags=' attribute for a new topic.
