|
|
|
```rust

|
|
text: "def create_order...",
|
|
heading: Some("function create_order"),
|
|
}
|
|
```
|
|
|
|
## 🔍 Example: Parsing `orders.py`
|
|
|
|
### Input File
|
|
```python
|
|
class OrderService:
|
|
def __init__(self, db):
|
|
self.db = db
|
|
|
|
def create_order(self, user_id, items):
|
|
"""Create a new order"""
|
|
order = {'user_id': user_id, 'items': items}
|
|
return self.db.insert('orders', order)
|
|
|
|
def get_order(self, order_id):
|
|
return self.db.get('orders', order_id)
|
|
```
|
|
|
|
### Step 1: Discovery
|
|
```
|
|
FileRecord {
|
|
path: "example/orders.py"
|
|
size: 458 bytes
|
|
fingerprint: "9f0c7d2e..."
|
|
}
|
|
```
|
|
|
|
### Step 2: Parsing
|
|
```
|
|
Document {
|
|
symbols: [
|
|
Symbol { name: "OrderService", kind: Class, lines: 1-11 },
|
|
Symbol { name: "__init__", kind: Function, lines: 2-3 },
|
|
Symbol { name: "create_order", kind: Function, lines: 5-8 },
|
|
Symbol { name: "get_order", kind: Function, lines: 10-11 },
|
|
],
|
|
imports: [],
|
|
facts: [],
|
|
}
|
|
```
|
|
|
|
### Step 3: Chunking
|
|
```
|
|
Chunks: [
|
|
Chunk { lines: 1-11, heading: "class OrderService" },
|
|
Chunk { lines: 2-3, heading: "function __init__" },
|
|
Chunk { lines: 5-8, heading: "function create_order" },
|
|
Chunk { lines: 10-11, heading: "function get_order" },
|
|
]
|
|
```

## 🚀 What's Next?
|
|
|
|
### Step 4: BM25 Indexing (Tantivy)
|
|
```
|
|
Chunk → Tantivy Index
|
|
Fields: path, heading, text
|
|
Ranking: BM25
|
|
```
|
|
|
|
### Step 5: Vector Embeddings (ONNX)
|
|
```
|
|
Chunk → all-MiniLM-L6-v2 → 384D vector → Qdrant
|
|
Semantic search with HNSW
|
|
```
|
|
|
|
### Step 6: Symbol Graph
|
|
```
|
|
Symbols + Imports → Edges
|
|
"OrdersPage imports getOrders"
|
|
"create_order calls db.insert"
|
|
```
|
|
|
|
### Step 7: Wiki Synthesis
|
|
```
|
|
Facts + Symbols + Graph → Generated Pages
|
|
- Overview (languages, scripts, ports)
|
|
- Dev Guide (setup, run, test)
|
|
- Flows (user journeys)
|
|
```
|
|
|
