## 🎯 Enhanced Linux Compilation with Improved Code Input
**Multiple Ways to Input Large Python Scripts**
This app now provides better support for large Python scripts with:
- **Larger code editor** (50+ lines visible, expandable to 100+ lines)
- **File upload option** for existing .py files
- **Clear and format buttons** for code management
- **Expand editor button** for even larger scripts
- **Enhanced network error handling** for runtime issues
## 📝 Code Input Methods
### 1. Type Code Directly
- Use the large code editor (50 lines visible by default)
- Auto-expanding up to 100+ lines as you type
- Syntax highlighting for Python
- Easy to scroll through long scripts
### 2. Upload Python Files
- Switch to "Upload File" mode
- Upload .py or .txt files
- Automatically loads the content into the editor
- Shows file size and name
### 3. Code Management Tools
- **Clear Code**: Remove all content instantly
- **Format Code**: Auto-format using black (if available)
- **Expand Editor**: Increase visible lines for very large scripts
## 📋 Usage Instructions for Large Scripts
### Option 1: File Upload
1. Switch input method to "Upload File"
2. Click "Choose File" and select your .py file
3. Click "Load File" to import the content
4. Configure requirements and compilation options
5. Click "Compile with Nuitka"
### Option 2: Direct Editing
1. Keep input method as "Type Code"
2. Start typing or paste your large script
3. Use the code editor's scroll bar for navigation
4. Click "Expand Editor" if you need more visible lines
5. Configure and compile as usual
## 🔧 Tips for Large Scripts
**Organization:**
1. **Break down large scripts** into functions and classes
2. **Add comments** to help navigate your code
3. **Use consistent indentation** for readability
4. **Group imports at the top** of your script
**Performance:**
1. **Minimize dependencies** for faster compilation
2. **Avoid complex nested structures** when possible
3. **Use efficient algorithms** for better runtime performance
4. **Test smaller parts** before compiling the full script
**Error Handling:**
1. **Add try/except blocks** for robust error handling
2. **Handle user input gracefully** with validation
3. **Include network error handling** (automatically added)
4. **Provide clear error messages** for users
## 🌐 Network Error Handling for Large Scripts
Even with large scripts, the network error handling remains effective:
```python
# Automatically added to all compiled scripts
try:
# Your network operations
response = urllib.request.urlopen('https://api.example.com')
except urllib.error.URLError as e:
if 'could not resolve host' in str(e.reason).lower():
print("✓ Network error detected and handled gracefully")
sys.exit(6) # Consistent exit code
```
## 📊 Code Editor Features
**Enhanced Layout:**
- **50 lines visible** by default (vs 20-28 in typical editors)
- **Auto-expansion** up to 100+ lines as needed
- **Scrollable interface** for unlimited script size
- **Syntax highlighting** for Python code
- **Line numbers** for easy navigation
**Management Tools:**
- **File upload support** for existing scripts
- **One-click clearing** for starting fresh
- **Code formatting** (if black is available)
- **Editor expansion** for very large scripts
- **File information display** when uploading
## 🚀 Best Practices for Large Scripts
**Before Compilation:**
1. **Test your script locally** to ensure it works
2. **Verify all imports** are included in requirements.txt
3. **Check for syntax errors** using the editor
4. **Consider script size** - larger scripts take longer to compile
**During Compilation:**
1. **Monitor progress** through the real-time logs
2. **Watch for errors** in the compilation output
3. **Be patient** - large scripts need more time
4. **Check requirements** if compilation fails
**After Compilation:**
1. **Download the binary** immediately
2. **Test on a clean system** if possible
3. **Verify network error handling** works
4. **Document any dependencies** for users
## ⚠️ Limitations and Workarounds
**File Size Limits:**
- Gradio may have upload size limits
- **Workaround**: Break very large scripts into modules
**Memory Usage:**
- Large scripts use more compilation memory
- **Workaround**: Use "Portable Binary" mode for lighter builds
**Compilation Time:**
- Large scripts take longer to compile
- **Workaround**: Test with smaller versions first
**Browser Performance:**
- Very large code may slow the interface
- **Workaround**: Use file upload for scripts >1000 lines

## 🧠 Enhanced Code Input + Compilation
**Major Improvements for Large Scripts:**
### 1. Flexible Input Methods
```python
# Two main input approaches:
# 1. Direct typing with expandable editor
# 2. File upload for existing scripts
```
### 2. Enhanced Code Editor
- **50+ lines visible** by default (expandable to 100+)
- **Auto-scrolling interface** for unlimited script size
- **Syntax highlighting** and line numbers
- **Multiple management tools** (clear, format, expand)
### 3. File Upload System
```python
# Supports multiple file types:
# - .py files (Python scripts)
# - .txt files (text-based scripts)
# - Automatic encoding detection
# - File size and name display
```

def load_script_from_file(file):
# Handles multiple encodings automatically
# UTF-8 primary, latin-1 fallback
# Error handling for corrupted files
# File size reporting
```
**Management Tools:**
```python
# Clear code: Instant reset
def clear_code():
return ""
# Format code: Using black if available
def format_code(code):
try:
import black
return black.format_str(code, mode=black.FileMode())
except:
return code # Graceful fallback
```
