Tag - XML Generator UI

A fast, lightweight Windows application for generating XML tags with attributes through a simple text interface.

Features

• Real-time XML generation - See XML output update instantly as you type
• Intuitive syntax - Use tabs to separate tag names, attributes, and values
• Smart attribute handling - Automatically distinguishes boolean attributes from key-value pairs
• Two output modes:
  • Type mode (Enter) - Types XML directly into the active application with reliable Shift+Enter line breaks
  • Clipboard mode (Ctrl+Enter or Shift+Enter) - Copies XML to clipboard
• Undo/Redo support - Undo changes with Ctrl+Z and redo with Ctrl+Y
• Clipboard paste - Paste clipboard content into a value (after first tab) using Ctrl+V
• XML mode toggle - Switch between regular tags and self-closing tags (e.g., <br />) with Ctrl+S
• Special character escaping - Replaces unsupported characters with ~ and escapes &, <, >, and " in attribute values
• Text wrapping - Automatically wraps long lines in the display view for readability
• Multi-monitor support - Opens on the monitor where your mouse cursor is located
• Clean, modern UI - Built with the Sokol graphics library

Quick Start

1. Run tag.exe
2. Type your tag structure using tabs to separate elements
3. (Optional) Use Ctrl+V to paste clipboard content into an attribute value, Ctrl+Z/Ctrl+Y to undo/redo, or Ctrl+S to toggle between regular and self-closing tag modes
4. Press Enter to type the XML into the active window, or Ctrl+Enter/Shift+Enter to copy XML to the clipboard and quit
