joe is, IMO, the best of the editors-that-aren't-vi. It's a decent full-featured editor in its own right, rather than a stripped down featureless minimal editor like
If invoked as
joe, the default key-bindings are WordStar-like which have also been used in many other programs over the years, including the editor in the Borland Turbo Pascal & Turbo C IDEs, so should be familiar to many users. If invoked as
jmac the key-bindings are
emacs-like. The key-bindings are configurable and if you can't find a configuration that exactly suits you, you can add one yourself or copy-and-modify an existing one.
I'm too much of a
vi user to use it myself, but I frequently recommend it to people who don't like or want to learn a modal editor like
vi, with good results.
Here's the description in the debian package:
Joe, or Joe's Own Editor, has the feel of most PC text editors: the key sequences are reminiscent of WordStar and Turbo C editors, but the feature set is much larger than of those. Joe has all of the features a Unix user should expect: full use of termcap/terminfo, complete VI-style Unix integration, a powerful configuration file, and regular expression search system. It also has six help reference cards which are always available, and an intuitive, simple, and well thought-out user interface.
Joe has a great screen update optimization algorithm, multiple windows (through/between which you can scroll) and lacks the confusing notion of named buffers. It has command history, TAB expansion in file selection menus, undo and redo functions, (un)indenting and paragraph formatting, filtering highlighted blocks through any external Unix command, editing a pipe into or out of a command, and block move, copy, delete or filter.
Through simple QEdit-style configuration files, Joe can be set up to emulate editors such as Pico and Emacs, along with a complete imitation of WordStar, and a restricted mode version (lets you edit only the files specified on the command line). Joe also has a deferred screen update to handle typeahead, and it ensures that deferral is not bypassed by tty buffering. It's usable even at 2400 baud, and it will work on any kind of sane terminal.
It is, AFAIK, packaged for all distros, and source is available at http://joe-editor.sourceforge.net/ - the debianised source should compile on Raspian if there isn't already a binary package.
