Mercury Editor

Key Features

* Simple: Mercury comes bundled as a Rails Engine, so just include it in your Gemfile. Or download the current bundled package if you're not using Rails. * Extendable: Full HTML, Simple, Markdown, Snippet and Image regions are supported by default, but you can just extend the base regions to build your own types. * Unobtrusive: We don't inject javascript or css into your production pages so you're free to use whatever frameworks you want without having to worry about conflicts. * HTML5: Built on top of the HTML5 contentEditable features, it natively supports the all the fancy new HTML5 elements, syntax, and JavaScript APIs. * Configurable: Easily add or remove toolbar items or create entirely new tools. Any toolbar item can be tied to an action using behaviors and the command pattern. * Open-source: Built for and maintained by the community via GitHub. You can track or report issues, contribute code or translations, and keep up with the project. * Full HTML Regions: Full HTML markup that utilizes the HTML5 contentEditable feature. These are the core of what Mercury Editor does, and provide the most flexibility. * Simple Regions: Plain text, newlines and markup aren't allowed. Appropriate for titles, headlines, or any area where you want just the content and not the styles. * Markdown Regions: Based on the Github flavored Markdown syntax. These are useful if you want to keep the markup flexible, while still clean and simple. * Snippets Regions: Allows snippets but not content. Snippets are chunks of reusable markup or code defined by a developer and can be placed into content later. * Image Regions: Only applied to image tags, it results in the image being drag-and-drop replaceable. Great for images you don't want within content regions. * Custom Regions: When the provided regions don't give you what you need, create your own based on your specific needs. You'll be the most appreciated developer.
