Zile Is Lossy Emacs (Zile) is a small Emacs clone. It’s also a free software, C language toolkit for developing text editors.
Zile is a customizable, self-documenting real-time display editor. It’s a lightweight clone that provides a subset of Emacs’s functionality suitable for basic editing.
Zile was written to be as similar as possible to Emacs; every Emacs user should feel comfortable with Zile.
Zile is distinguished by a very small RAM memory footprint, of approximately 130kB, and quick editing sessions. It is 8-bit clean, allowing it to be used on any sort of file. Zile is a collection of algorithms and data-structures that currently support all basic Emacs-like editing features. The number of editing buffers and windows is only limited by available memory and screen space respectively. Registers, minibuffer completion and auto fill are available.
Like Emacs, Zemacs is self-documenting: it has built-in help on its features.
