🎨 Design Features

Unicode Symbols

  • ◆ - Current HEAD commit (bright yellow)
  • ◉ - Regular commits (cyan)
  • ● - Current branch (bright green)
  • ○ - Other branches (cyan)
  • │ - Connection lines (cyan)
  • ─ - Horizontal lines (cyan)
  • ╭╮╰╯ - Box corners (cyan)
  • ✓ - Success (bright green)
  • ✘ - Error (red)
  • ⚠️ - Warning (yellow)
  • 🌿 - Branch emoji
  • 📝 - Changes emoji

Colors

  • Bright Green - Success ✓, additions, current selection
  • Red - Errors ✘, deletions
  • Yellow - Warnings ⚠️, modifications
  • Bright Cyan - Headers, labels, borders
  • White - Regular text content

Styling

  • Rounded box borders for status
  • Horizontal line separators for headers
  • Proper indentation and alignment
  • Clear visual hierarchy
  • Professional appearance

🖥️ Terminal Support

Works on:

  • ✓ Linux (all terminals)
  • ✓ macOS (Terminal, iTerm2, etc.)
  • ✓ Windows (Windows Terminal, ConEmu, etc.)
  • ✓ SSH sessions
  • ✓ Git Bash
  • ✓ WSL (Windows Subsystem for Linux)
  • ✓ CI/CD pipelines (auto-detects and disables colors when piped)
  • ✓ Legacy terminals (with ASCII fallback)

🚀 Performance

  • Zero overhead - Formatting only on output
  • No external I/O - Pure string operations
  • Minimal memory - Strings built in-place
  • Fast startup - No initialization cost

🔧 How It Works

Every MUG command that produces output now uses the beautiful formatter:

  1. Gather data (commits, branches, etc.)
  2. Create formatter: UnicodeFormatter::new(true, true)
  3. Format data: formatter.format_log(&commits)
  4. Print result: println!("{}", formatted_output)

The formatter handles:

  • Unicode character selection (with ASCII fallback)
  • Color injection (with auto-detection)
  • Alignment and spacing
  • Symbol generation
  • All the visual magic

📊 What Changed

Before After
Plain text output Beautiful colored output
* main for branches ● main (current) with colors
One-line log Beautiful multi-line with symbols
Plain messages Colored success/error/warning
Generic status Styled box with emojis
No visual feedback Clear visual status at a glance
