{"slug": "ysh-terminal-v8-1-4", "title": "YSH Terminal v8.1.4", "summary": "A developer released YSH Terminal v8.1.4, a Java Swing-based command-line emulator that implements an in-memory file and folder system, a note-taking subsystem, LAN chat and file sharing over sockets with multi-client support, command history, theming, and a Konami-code easter egg. The single-file Java program uses javax.swing components with a custom DocumentFilter to manage prompt positioning and input handling.", "body_md": "|  | // YSH is Built through verions NOT Generated. | \n|  | // Comments are for better understanding not AI prove ( dont be chay . ) | \n|  | // JAVA CLASSES | \n|  | import javax.swing.*;
