description	Guide for Splitrail's terminal UI and file watching. Use when modifying the TUI, stats display, or real-time update logic.

Real-Time Monitoring & TUI

Splitrail provides a terminal UI with live updates when analyzer data files change.

Source Files

• src/tui.rs - TUI entry point and rendering
• src/tui/logic.rs - TUI state management and input handling
• src/watcher.rs - File watching implementation

Components

FileWatcher (src/watcher.rs)

Watches analyzer data directories for changes using the notify crate. Triggers incremental re-parsing on file changes and updates TUI via channels.

RealtimeStatsManager

Coordinates real-time updates: background file watching, auto-upload to Splitrail Cloud (if configured), and stats updates to TUI via tokio::sync::watch.

TUI (src/tui.rs, src/tui/logic.rs)

Terminal interface using ratatui:

• Daily stats view with date navigation
• Session view with lazy message loading
• Real-time stats refresh

Key Patterns

• Channel-based updates - Stats flow through tokio::sync::watch channels
• Lazy message loading - Messages loaded on-demand for session view to reduce memory

Adding Watch Support to an Analyzer

Implement get_watch_directories() in your analyzer to return root directories for file watching. See src/analyzer.rs for the trait definition.
