jedit - 5.5.0+dfsg-2 main

As one of the most feature rich editors available, jEdit boasts support for
syntax highlighting in more than 140 languages. jEdit combines the power of
Emacs, the user-friendliness of Kate, and the advanced editing features
(such as vertical paste) of Ultraedit, to bring you an open-source
plugin-based programmer's editor of professional quality.
.
It is possible to define complex macros in BeanShell or Jython, or other
languages that fit into the BSF. jEdit offers a powerful and user-friendly
keyboard mapping system (including 2-keystroke shortcuts), making it
possible to give jEdit a very Emacs-like feel, if you so desire.
.
Its functionality is easily extended by the use of 'plugins' which can be
downloaded, updated, and installed, all without exiting the editor. These
include a built-in Console shell integration, which lets you execute
interactive external commands inside your editor, as well as bind them to
keyboard shortcuts. The FTP plugin lets you browse and edit files on remote
systems over FTP or SFTP. Other plugins provide shells, object oriented
structure/code browsers, or completion popups for Java, XML, HTML, Ant,
LaTeX, Python, Ruby, Perl, C, C++, bash, Scheme, Prolog, and many other
languages.
