Setup TFE Event Logging

You are adding debug event logging to TFE so I can monitor what's happening in the application in real-time.

Your Task

Add a debug logging system to TFE that logs events to /tmp/tfe-events.jsonl.

Step 1: Add Debug Logger to Model

Edit types.go to add a debug log file handle:

type model struct {
    // ... existing fields ...
    debugLog *os.File  // Add this field
}

Step 2: Create Debug Helper

Create or edit helpers.go to add logging functions:

func (m *model) enableDebugLogging() error {
    var err error
    m.debugLog, err = os.OpenFile("/tmp/tfe-events.jsonl",
        os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0644)
    return err
}

func (m *model) logEvent(event string, data interface{}) {
    if m.debugLog == nil {
        return
    }

    entry := map[string]interface{}{
        "time":  time.Now().Format("15:04:05.000"),
        "event": event,
        "data":  data,
    }

    json.NewEncoder(m.debugLog).Encode(entry)
}

func (m *model) closeDebugLog() {
    if m.debugLog != nil {
        m.debugLog.Close()
    }
}

Step 3: Initialize Logger

Edit model.go in the initialModel() function:

func initialModel() model {
    m := model{
        // ... existing initialization ...
    }

    // Enable debug logging if TFE_DEBUG env var is set
    if os.Getenv("TFE_DEBUG") == "1" {
        m.enableDebugLogging()
    }

    return m
}

Step 4: Add Logging Calls

Add strategic logging calls throughout the codebase:

In file_operations.go:

func (m *model) loadPreview(path string) {
    m.logEvent("preview_load_start", map[string]string{"path": path})

    // ... existing code ...

    m.logEvent("preview_loaded", map[string]interface{}{
        "path": path,
        "size": len(content),
        "lines": strings.Count(content, "\n"),
    })
}

func (m *model) loadFiles(path string) ([]fileItem, error) {
    m.logEvent("load_directory", map[string]string{"path": path})

    // ... existing code ...

    m.logEvent("directory_loaded", map[string]interface{}{
        "path": path,
        "file_count": len(files),
    })

    return files, nil
}
