# Launch Script Updates

This document outlines the updates made to `launch.sh` to work with the new automated Trackio deployment features.

## Key Changes Made

### ✅ **Removed Manual Username Input**
- **Before**: Script asked for username manually
- **After**: Username is automatically extracted from HF token using `whoami()`
- **Benefit**: Fewer manual inputs, better user experience

### ✅ **Updated Token Validation**
- **Before**: `validate_hf_token()` only validated token
- **After**: `validate_hf_token_and_get_username()` validates token AND extracts username
- **Benefit**: Automatic username detection from token

### ✅ **Updated Deployment Workflow**
- **Before**: Passed username manually to deployment script
- **After**: Deployment script automatically gets username from token
- **Benefit**: Consistent with new automated features

### ✅ **Enhanced User Feedback**
- **Before**: Basic status messages
- **After**: Clear information about automated features
- **Benefit**: Users understand what's happening automatically

## Updated Workflow

### **Step 1: Authentication (Simplified)**
```bash
# Before: Asked for username + token
get_input "Hugging Face username" "" HF_USERNAME
get_input "Hugging Face token" "" HF_TOKEN

# After: Only asks for token, username auto-detected
get_input "Hugging Face token" "" HF_TOKEN
# Username automatically extracted from token
```

### **Step 9: Trackio Space Deployment (Automated)**
```bash
# Before: Manual input file creation
cat > deploy_input.txt << EOF
$HF_USERNAME
$TRACKIO_SPACE_NAME
$HF_TOKEN
$GIT_EMAIL
$HF_USERNAME
EOF
python deploy_trackio_space.py < deploy_input.txt

# After: Direct input with automated features
python deploy_trackio_space.py << EOF
$TRACKIO_SPACE_NAME
$HF_TOKEN
$GIT_EMAIL
$HF_USERNAME
EOF
```

### **Step 10: Dataset Setup (Automated)**
```bash
# Before: Basic dataset setup
python setup_hf_dataset.py

# After: Automated dataset setup with user feedback
print_info "Setting up HF Dataset with automated features..."
print_info "Username will be auto-detected from token"
print_info "Dataset repository: $TRACKIO_DATASET_REPO"
python setup_hf_dataset.py
```

### **Step 11: Trackio Configuration (Automated)**
```bash
# Before: Basic configuration
python configure_trackio.py

# After: Automated configuration with user feedback
print_info "Configuring Trackio with automated features..."
print_info "Username will be auto-detected from token"
python configure_trackio.py
```

## New Function: `validate_hf_token_and_get_username()`

```bash
validate_hf_token_and_get_username() {
    local token="$1"
    if [ -z "$token" ]; then
        return 1
    fi
    
    # Test the token and get username
    export HF_TOKEN="$token"
    if hf whoami >/dev/null 2>&1; then
    # Get username from whoami command
    HF_USERNAME=$(hf whoami | head -n1 | tr -d '\n')
        return 0
    else
        return 1
    fi
}
```

## User Experience Improvements

### ✅ **Fewer Manual Inputs**
- Only need to provide HF token
- Username automatically detected
- Git email still required (for git operations)

### ✅ **Better Feedback**
- Clear messages about automated features
- Shows what's happening automatically
- Better error messages

### ✅ **Consistent Automation**
- All scripts now use automated features
- No manual username input anywhere
- Automatic secret setting

## Configuration Summary Updates

### **Before:**
```
📋 Configuration Summary:
========================
  User: username (manually entered)
  Experiment: experiment_name
  ...
```

### **After:**
```
📋 Configuration Summary:
========================
  User: username (auto-detected from token)
  Experiment: experiment_name
  ...
```

## Benefits

1. **Simplified Workflow**: Only need token, username auto-detected
2. **Consistent Automation**: All scripts use automated features
3. **Better User Experience**: Clear feedback about automated features
4. **Reduced Errors**: No manual username input means fewer typos
5. **Streamlined Process**: Fewer steps, more automation

## Testing

The updated launch script has been tested for:
- ✅ Syntax validation (`bash -n launch.sh`)
- ✅ Function integration with updated scripts
- ✅ Automated username extraction
- ✅ Consistent workflow with new features

## Compatibility

The updated launch script is fully compatible with:
- ✅ Updated `deploy_trackio_space.py` (automated features)
- ✅ Updated `setup_hf_dataset.py` (username extraction)
- ✅ Updated `configure_trackio.py` (automated configuration)
- ✅ Existing training and model push scripts

## Summary

The launch script now provides a seamless, automated experience that:
- Extracts username automatically from HF token
- Uses all the new automated features in the deployment scripts
- Provides clear feedback about automated processes
- Maintains compatibility with existing workflows
- Reduces manual input requirements
- Improves overall user experience
