# Flashcards
Spaced repetition system using the SM-2 algorithm. SQLite storage.
## Script
```bash
python3 scripts/flashcard_engine.py create-deck "Python基础"
python3 scripts/flashcard_engine.py add "Python基础" "GIL是什么?" "Global Interpreter Lock，全局解释器锁"
python3 scripts/flashcard_engine.py add "Python基础" "list和tuple的区别?" "list可变，tuple不可变" --type basic
python3 scripts/flashcard_engine.py add "Python基础" "Python的GIL是{{Global Interpreter Lock}}" --type cloze
python3 scripts/flashcard_engine.py due # show due cards
python3 scripts/flashcard_engine.py review <card_id> 4 # rate 0-5
python3 scripts/flashcard_engine.py stats "Python基础"
python3 scripts/flashcard_engine.py import cards.csv "Python基础"
```
## SM-2 Algorithm
Quality rating (0-5):
- 0-2: Incorrect (reset interval to 1 day)
- 3: Correct but hard (keep interval)
- 4: Correct (normal progression)
- 5: Easy (accelerate interval)
```python
def sm2(quality, repetitions, easiness, interval):
if quality >= 3:
if repetitions == 0: interval = 1
elif repetitions == 1: interval = 6
else: interval = round(interval * easiness)
repetitions += 1
else:
repetitions = 0
interval = 1
easiness = max(1.3, easiness + 0.1 - (5 - quality) * (0.08 + (5 - quality) * 0.02))
return repetitions, easiness, interval
```
## Card Types
- **Basic**: front → back
- **Cloze**: `Python的GIL是{{Global Interpreter Lock}}` → shows blank
- **Reverse**: auto-generates both directions
## Storage
SQLite at `~/.echo-agent/flashcards.db`:
```sql
CREATE TABLE decks (id INTEGER PRIMARY KEY, name TEXT UNIQUE, created_at TEXT);
CREATE TABLE cards (
id INTEGER PRIMARY KEY, deck_id INTEGER,
front TEXT, back TEXT, card_type TEXT DEFAULT 'basic',
repetitions INTEGER DEFAULT 0, easiness REAL DEFAULT 2.5,
interval INTEGER DEFAULT 0, next_review TEXT,
created_at TEXT DEFAULT CURRENT_TIMESTAMP
);
```
## Channel Integration
Schedule daily review delivery: send due cards as quiz messages through Telegram/WeChat at configured time.
## CSV Import Format
```csv
front,back
What is Python?,A programming language
GIL是什么?,Global Interpreter Lock
```
