|
||||
# 输出: 脚本已生成: temp_scripts/script_a1b2c3d4.py
|
||||
|
||||
# 第二次执行相同需求：复用脚本
|
||||
python3 scripts/auto_script.py "计算总价 = 单价 * 数量" --file data2.xlsx
|
||||
# 输出: 复用已存在脚本: temp_scripts/script_a1b2c3d4.py

python scripts/auto_script.py "计算利润" --dry-run
|
||||
|
||||
# JSON 格式输出
|
||||
python scripts/auto_script.py "清洗数据" --output-format json
|
||||
```
|
||||
|
||||
#### 脚本缓存机制
|
||||
|
||||
相同的需求会自动复用已生成的脚本，避免重复生成：
|
||||
|
||||
```bash
|
||||
# 第一次执行：生成并执行脚本
|
||||
python scripts/auto_script.py "计算总价 = 单价 * 数量" --file data.xlsx
|
||||
|
||||
# 第二次执行相同需求：直接复用已有脚本
|
||||
python scripts/auto_script.py "计算总价 = 单价 * 数量" --file data2.xlsx
|
||||
```
|
||||
|
||||
缓存文件位置：`temp_scripts/script_[hash].py`
|
||||
|
||||
清空缓存：
|
||||
```bash
|
||||
rm -rf temp_scripts/
|
||||
```
|
||||

A: 脚本保存在 `temp_scripts/` 目录，命名格式为 `script_[hash].py`。
|
||||
|
||||
```bash
|
||||
ls temp_scripts/
|
||||
cat temp_scripts/script_[hash].py
|
||||
```
|
||||
|
||||
### Q: 如何自定义脚本模板？
|
||||
|
