Mercury Editor is a WYSIWYG rich-text editor for Rails applications that enables full inline page editing using HTML5 contentEditable regions instead of iframes. It provides a single shared toolbar across editable regions and is built with CoffeeScript and jQuery on top of Rails 3.2.

Use cases

• add inline wysiwyg editing to rails pages
• let users edit whole pages in place like a cms
• embed a rich text editor without iframes
• build editable regions with a shared toolbar
• replace tinymce or ckeditor in a rails app
• enable content editing directly on rendered html

When to choose

• you maintain a legacy Rails 3.2 app already using Mercury
• you need full-page inline editing with contentEditable rather than iframe-based editors
• you want a single toolbar shared across multiple editable regions on a page

When to avoid

• starting a new project - the repo is deprecated and no longer maintained
• you need support for legacy browsers or non-W3C-compliant engines
• your stack is not Ruby on Rails
• you need an actively maintained editor with modern security patches
