emil

emil is a minimalist, Emacs-style text editor designed specifically for terminal usage, making it lightweight and efficient for editing UTF-8 files. Written in standard C99, it is capable of running on any system that provides a minimal POSIX.1-2001 interface and a VT100-compatible terminal. This editor simplifies the text editing experience by avoiding common complexities such as scripting, plugins, configuration files, and auto-save functionalities.

Shell Integration

emil supports shell commands embedded directly within its interface. This feature allows users to execute commands on selected text and manage the output efficiently. Common tasks include:

• Fill a region using fmt: Ctrl-u Alt-|
