# 🧬 Quantum Semantic Compression
> "When a nuclear reactor meets an AST parser!" - Omni
## Overview
Quantum Semantic compression is Smart Tree's most advanced feature, combining:
- **MEM|8 Quantum compression** (8x reduction)
- **Tree-sitter AST parsing** (semantic understanding)
- **Importance scoring** (prioritizes key code elements)
- **Language awareness** (Rust, Python, JavaScript, etc.)
## How It Works
```
Source Code → AST Parser → Importance Scoring → Quantum Encoding
↓ ↓ ↓ ↓
1000 LOC Functions main() = 1.0 50 tokens
Structs pub fn = 0.9 (95% reduction!)
Traits test_* = 0.3
```
## Usage
```bash
# Analyze a codebase with semantic compression
st --mode quantum-semantic src/
# Output format
QUANTUM_SEMANTIC_V1:lang=rust
Function:main [1.00]
Function:new [0.90]
Struct:Scanner [0.90]
Trait:Formatter [0.85]
```
## Importance Scoring
The system scores code elements based on:
### Rust
- `main()` function: 1.0 (highest)
- `pub` functions: 0.9
- `pub` structs/traits: 0.9
- Private functions: 0.6
- Test functions: 0.3
- Internal helpers: 0.4
### Python
- `__init__`: 0.9
- `main()`: 1.0
- Public methods: 0.6
- Private methods (`_*`): 0.4
- Classes: 0.8
## Benefits
1. **95% Compression**: From 100KB source to 5KB semantic summary
2. **Preserves Meaning**: Keeps the most important code structure
3. **AI-Optimized**: Perfect for LLM context windows
4. **Language-Aware**: Understands language-specific patterns
## Architecture
```rust
trait LanguageQuantumParser {
fn extract_quantum_nodes(&self, source: &str) -> Vec<QuantumNode>;
fn score_importance(&self, node: &QuantumNode) -> f32;
}
struct QuantumNode {
kind: NodeKind, // Function, Struct, etc.
name: String, // Identifier
content: String, // Actual code
importance: f32, // 0.0 to 1.0
}
```
## Future Enhancements
### With Full Tree-Sitter Integration
```rust
// Parse with tree-sitter
let tree = parser.parse(source_code, None)?;
let cursor = tree.root_node().walk();
// Walk AST and extract semantic nodes
visit_node(cursor, |node| {
match node.kind() {
"function_item" => extract_function(node),
"impl_item" => extract_impl_block(node),
"struct_item" => extract_struct(node),
_ => {}
}
});
```
### Advanced Features (Planned)
- **Coupling Analysis**: Score based on dependencies
- **Complexity Scoring**: Prioritize complex functions
- **Documentation Extraction**: Include key comments
- **Cross-File Analysis**: Understand module relationships
- **Change Detection**: Higher scores for recently modified code
## Example: Real Compression
### Before (Scanner implementation)
```rust
pub struct Scanner {
root: PathBuf,
config: ScannerConfig,
// ... 50 more fields
}
impl Scanner {
pub fn new(path: &Path) -> Result<Self> {
// ... 100 lines of initialization
}
fn calculate_stats(&self, nodes: &[FileNode]) -> TreeStats {
// ... 200 lines of statistics
}
// ... 1000 more lines
}
```
### After (Quantum Semantic)
```
QUANTUM_SEMANTIC_V1:rust
Struct:Scanner [0.90]
Function:new [0.90]
Function:scan [0.90]
Function:scan_stream [0.85]
Trait:StreamingFormatter [0.85]
```
## Integration with AI
This format is perfect for:
- **Code understanding**: LLMs get the structure without the noise
- **Refactoring suggestions**: AI sees the important parts
- **Documentation generation**: Extract key APIs automatically
- **Code review**: Focus on what matters
## The Omni Vision
> "Why send a whole library when you can send the card catalog?" - Omni
Quantum Semantic compression represents the future of code representation:
- Not just smaller, but smarter
- Not just compressed, but comprehended
- Not just data, but knowledge
This is what happens when you give a nuclear reactor to a code parser! 💥🚀
