Obfuscate Mode

obfuscate-mode is a lightweight Emacs minor mode that dynamically obfuscates text in a buffer. It is useful for hiding sensitive information or obfuscating text during presentations or while working in shared environments.

Features

• Dynamic Obfuscation: Only obfuscates visible portions of the buffer for optimal performance.
• Customizable Obfuscation Character: Choose the character used to obfuscate text.
• Lightweight and Compatible: Uses modern Emacs features like jit-lock and text properties to integrate smoothly with other functionality.

Installation

1. Save obfuscate-mode.el to a directory in your Emacs load-path.
2. Add the following to your Emacs configuration:

   (require 'obfuscate-mode)

Usage

To enable obfuscate-mode, run:

M-x obfuscate-mode

This will obfuscate all visible text in the current buffer. The obfuscation is dynamic, meaning it will automatically apply to newly visible regions as you scroll.

Customization

You can customize the obfuscation character by setting obfuscate-mode-obfuscation-character:

(setq obfuscate-mode-obfuscation-character "\u25A0") ; Solid square

The default obfuscation character is a hollow square (▢, Unicode \u25A1).
