Implement TUI with binaries list, versions view, add binary workflow, tab navigation, and intelligent defaults

[Copilot]

Implements the TUI specification from tui.plan.md. Provides interactive management of binary configurations with read-only browsing, URL-based binary addition, and tab-based navigation with intelligent environment-based defaults.

Architecture

View State Management

• Bubble Tea message-based architecture with typed view states
• Separate rendering functions per view (view_*.go)
• Data layer uses repository pattern with optimized JOIN queries
• Window size tracking for responsive layout

URL Parser

• Extracts owner/repo/version/asset from GitHub release URLs
• Auto-generates binary ID from asset prefix (e.g., copilot-linux-x64.tar.gz → copilot)
• Supports .tar.gz, .zip, .tgz formats

Styling

• Orange color scheme (#F97316) matching the box icon
• Responsive proportional column widths that adapt to terminal size
• Tab navigation system with visual highlighting

Components

Binaries List

• Displays configured binaries with active version and install count
• Proportional column widths (35%, 15%, 30%, 20%) adapt to terminal size
• Arrow navigation, press a to add, Enter to view versions
• Tab bar below header for quick view switching

Versions View

• Shows all installed versions for a binary with proportional columns (5%, 20%, 20%, 15%, 40%)
• Active version indicator, human-readable sizes, intelligent date formatting
• Responsive layout adapts to terminal width
• Auto-detects date format from system locale/timezone

Add Binary Workflow

1. URL input with real-time validation
2. Parsed config form (8 editable fields)
3. Tab navigation, Ctrl+S to save to database
4. Duplicate ID detection, required field validation

Tab Navigation

• Accessible views: Binaries, Downloads, Configuration, Help
• Active tab highlighted in orange
• Multiple navigation methods:
  • Number keys (1-4) for direct access
  • Shift+Tab to cycle to next tab
  • Ctrl+Shift+Tab to cycle to previous tab
• Placeholder views for future functionality

Technical Notes

Dependencies

• Uses bubbles/textinput for form inputs
• Leverages Bubble Tea and Lipgloss for TUI framework

Database Integration

• Config digest calculation via crypto.ComputeDigest
• Auto-syncs config.json to database on launch
• ConfigVersionManual = 0 distinguishes TUI-added binaries from config-sourced
• Repository pattern with ListWithVersionDetails() method for optimized queries

Date Formatting

• Intelligent default detection from environment variables (LC_TIME, LC_ALL, LANG)
• Falls back to timezone detection for European vs US formats
• User can override via config.json dateFormat field
• Examples:
  • ISO format (default): "2006-01-02 15:04"
  • UK/EU format: "02/01/2006 15:04"
  • US format: "01/02/2006 15:04"

Code Quality

• Text truncation utilities with named constants
• No magic numbers - all layout values extracted to constants
• Reusable helper functions for common operations
• Comprehensive documentation and comments

Example URL parsing:

parsed, _ := url.ParseGitHubReleaseURL(
    "https://github.com/cli/cli/releases/download/v2.0.0/gh_2.0.0_linux_amd64.tar.gz")
// parsed.Owner = "cli"
// parsed.Repo = "cli" 
// parsed.Version = "v2.0.0"
// GenerateBinaryID(parsed.AssetName) = "gh"

Example config.json with date format override:

{
  "version": 1,
  "dateFormat": "02/01/2006 15:04",
  "binaries": [...]
}

Performance Optimizations

• Replaced N+1 database queries with single JOIN query in repository layer
• Uses computed columns for install count aggregation
• Reduces database overhead significantly for large binary collections
• Responsive layout calculations cached per render

Key Bindings

Tab Navigation:

• 1-4: Jump to specific tab
• Shift+Tab: Next tab
• Ctrl+Shift+Tab: Previous tab

Binaries List:

• ↑/↓: Navigate entries
• Enter: View versions
• a: Add binary
• q: Quit

Versions View:

• Esc: Back to list
• q: Quit

Add Binary:

• Tab/Shift+Tab: Navigate form fields
• Ctrl+S: Save
• Esc: Cancel
