Core Functionality

All core features tested and working correctly

📦

Compiler Examples

All 4 example files compile and run successfully

🔧

REPL Mode

Interactive mode works correctly with expression evaluation

⚙️

JavaScript Compilation

--compile flag generates proper JS output

✅ Verified Features

✅ Working Features

            ✅ Component Creation - Working with proper NixiValue objects
✅ Styling System - CSS-like styling with style "selector" { ... } syntax
✅ File Operations - ls, pwd, cd functions operational
✅ HTML Generation - saveHTML and renderHTML functions working
✅ Interactive REPL - Expression evaluation and debugging
✅ JavaScript Output - Compilation to standalone JavaScript files
✅ npm Scripts - All example scripts work as expected
✅ Test Suite - All tests pass (lexer, parser, interpreter, GUI)
✅ HTML Support - Direct HTML tag embedding and generation
✅ CSS Integration - Full CSS rule parsing and application
✅ JavaScript Integration - Inline JS code execution and evaluation
✅ DOM Manipulation - querySelector, addEventListener functions
✅ Web APIs - File I/O, element manipulation, event handling

          

⚠️ Known Limitations

            ⚠️ Component Parameters - Parser doesn't fully support parameterized component definitions
⚠️ Conditional Expressions - if-then-else syntax has parsing issues
⚠️ Array Access - array[index] syntax causes runtime errors
⚠️ HTML Tags - Extended support for all HTML5 tags, but complex nested structures may need refinement
⚠️ Variable Names - _ cannot be reused within the same scope
⚠️ JavaScript Integration - Security sandboxing for eval() functions needs implementation
⚠️ CSS Parsing - Advanced CSS features like media queries and animations need enhancement

          

🧪 Test Commands

Run Test Suite

# Run all tests
npm test

# Direct test execution
node tests/test.js

# Test individual components
# (Tests are structured to test lexer, parser, interpreter, and GUI separately)

Test Examples

# Test all examples
npm run example:gui
npm run example:math  
npm run example:dashboard

# Test REPL
npm start

# Test compilation
nixi --compile examples/simple-gui.nixi

🔧 Continuous Testing

Before Committing

Always run the full test suite before making changes:

npm test
npm run example:gui
npm run example:math
npm run example:dashboard

Test New Features

When adding new features, create corresponding tests:

# Add test to tests/test.js
function testNewFeature() {
  test('should handle new feature', () => {
    # Test implementation
    assertEqual(result, expected);
  });
}

Regression Testing

Ensure existing functionality still works after changes:

# Run all examples to verify no regressions
for example in examples/*.nixi; do
  nixi "$example"
done

# Check all generated HTML files
ls -la *.html
