jEdit Overview
jEdit is a free, open-source programmer's text editor for Windows, macOS, and Linux, written in Java and maintained by the jEdit Development Team. Because it runs on the Java platform, the same editor behaves consistently across operating systems. It is designed for working with source code and offers syntax highlighting for well over a hundred file types, auto-indentation, code folding, and a powerful search-and-replace that supports regular expressions across multiple files. One of jEdit's defining strengths is extensibility: a built-in plugin manager downloads and installs hundreds of community plugins that add features such as file-tree browsers, FTP editing, version-control integration, and language-specific tools, and its built-in macro system lets you automate tasks using BeanShell scripting. Customizable keyboard shortcuts, split editing panes, and unlimited undo round out a flexible editor aimed at developers. The official download is provided by the jEdit project.
