jEdit Markdown Plugin is a plugin for jEdit that can render Markdown text from the current buffer or from selected text. The resulting HTML is written to a new buffer or copied to the clipboard. The plugin can also show a preview in a Web browser (using the Info Viewer plugin).
Markdown is a lightweight markup language. It allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid HTML. This taglib brings Markdown to your JSP pages.
