jEdit is a mature programmer's text editor with hundreds (counting the time developing plugins) of person-years of development behind it.
While jEdit beats many expensive development tools for features and ease of use, it is released as free software and is available at no-cost through the Ubuntu repository with full source code.
The jEdit core, together with a large collection of plugins is maintained by a world-wide developer team.
Some of jEdit's features include:
* Written in Java, so it runs on Mac OS X, OS/2, Unix, VMS and Windows.
* Built-in macro language; extensible plugin architecture.
* Plugins can be downloaded and installed from within jEdit using the "plugin manager" feature.
* Auto indent, and syntax highlighting for more than 130 languages.
* Supports a large number of character encodings including UTF8 and Unicode.
* Folding for selectively hiding regions of text.
* Word wrap.
* Highly configurable and customizable.
