Eclipse Orion

Orion extensions and plugins

• Orion provides a service registry similar to the OSGi service model
• Orion implements the Eclipse concept of extensions and extension points using the Orion service registry
• Services and extensions that reside on different web domains from the host Orion server are contributed to Orion by registering plugins. A plugin is declared via an HTML file, is opened in a "head-less" child IFrame and uses window.postMessage to advertise capabilities in the form of services and extensions back to Orion

Markdown in a Nutshell

• Markdown is intended to be as easy-to-read and easy-to-write as possible.
• A Markdown-formatted document should be publishable as-is, as plain text, and can be read without looking like it’s been marked up with tags or formatting instructions.
• Markdown uses punctuation characters, carefully chosen so as to look like what they mean. e.g., asterisks around a word actually look like *emphasis*, markdown lists look like lists, etc.
• Markdown can be easily converted to structurally valid XHTML (or HTML).
• The single biggest source of inspiration for Markdown’s syntax is the format of plain text email.

Markdown Syntax Highlights

Block Elements (Paragraphs, Headers, Blockquotes, Lists, etc.)

• # This is an equivalent of H1
• ## This is an equivalent of H2
• > Blockquote
• * Unordered list item

Span Elements (Links, Emphasis, Code)

• **text in bold**
• inline [link](http://example.com) in text
• `console.info()` for inline code
