Yes-D: A Memory-Safe,yes Command in D

A modern, memory-safe implementation of Unix yes command in D. Outputs a string (default: "y") repeatedly to stdout until terminated. Built with D's @safe for memory safety and buffered I/O for efficiency.

Features

• Memory Safety: Prevents buffer overflows and undefined behavior via D's @safe
• Buffered I/O: Uses 64KB buffer for efficient output
• Simple Interface: Matches standard Unix yes command behavior
• Cross-Platform: Works on any D compiler-supported platform

Installation
