GNU Zile

GNU Zile is a text editor development kit, so that you can (relatively) quickly develop your own ideal text editor without reinventing the wheel for many of the common algorithms and data-structures needed to do so.

It comes with an example implementation of a lightweight Emacs clone, called Zmacs. Every Emacs user should feel at home with Zmacs. Zmacs is aimed at small footprint systems and quick editing sessions (it starts up and shuts down instantly).

More editors implemented over the Zile frameworks are forthcoming as the data-structures and interfaces improve: Zz an emacs inspired editor using Lua as an extension language; Zee a minimalist non-modal editor; Zi a lightweight vi clone; and more...

Zile is a collection of algorithms and data-structures that currently support all basic Emacs-like editing features: it is 8-bit clean (though Unicode support is not ready yet), and the number of editing buffers and windows is only limited by available memoryand screen space respectively. Registers, minibuffer completion and auto fill are available.

Zmacs implements a subset of Emacs with identical function and variable names, continuing the spirit of the earlier Zile editor implemented in C.

Downloading Zile

Zile can be found on the main GNU ftp server: http://ftp.gnu.org/gnu/zile/ (via HTTP) and ftp://ftp.gnu.org/gnu/zile/ (via FTP). It can also be found on the GNU mirrors; please use a mirror if possible.

Documentation

Like Emacs, Zmacs is self-documenting: it has built-in help on its features. It also comes with a brief man page, obtained by running man zmacs, and a FAQ, which can be found by running zmacs and typing the key-sequence C-h C-F.

Screenshots

Zmacs' splash screen

Zmacs is a lightweight Emacs clone; even its splash screen is very Emacs-like:

Selecting a region in Zmacs

Zmacs highlights the selected region, shown here editing some of the zlisp source code that implements set-screen-height:

Zz Syntax Highlighting Proof-of-Concept

Zz is another editor built using Zile, here using experimental Lua syntax-highlighting:

Mailing lists

Zile has two mailing lists: <help-zile@gnu.org> and <bug-zile@gnu.org>.

The main discussion list is <bug-zile@gnu.org>, and is used to discuss most aspects of Zile, including development and enhancement requests, as well as bug reports.

There is a separate list for general user help and discussion, <help-zile@gnu.org>.

Announcements about Zile and most other GNU software are made on <info-gnu@gnu.org>.

To subscribe to these or any GNU mailing lists, please send an empty mail with a Subject: header of just subscribe to the relevant -request list. For example, to subscribe yourself to the GNU announcement list, you would send mail to <info-gnu-request@gnu.org>. Or you can use the mailing list web interface.

Getting involved

Development of Zile, and GNU in general, is a volunteer effort, and you can contribute. For information, please read How to help GNU. If you'd like to get involved, it's a good idea to join the discussion mailing list (see above).

Development

For development sources, bug and patch trackers, and other information, please see the Zile project page at savannah.gnu.org.

Maintainer

Zile is currently being maintained by Gary V. Vaughan. Please use the mailing lists for contact.
