# geekcamp-calculator

基于 ANTLR4 编写的 Python 计算器 DEMO

## 环境准备

```bash
poetry install

poetry run antlr4 -Xexact-output-dir -o calculator/antlr4 -Dlanguage=Python3 calculator/grammar/CalculatorLexer.g4
poetry run antlr4 -Xexact-output-dir -o calculator/antlr4 -listener -visitor -Dlanguage=Python3 calculator/grammar/CalculatorParser.g4 calculator/grammar/CalculatorLexer.g4
```

## 单元测试

```bash
poetry run pytest -s
```

## 本地安装

```bash
poetry build -f wheel
pip install -U --user dist/geekcamp_calculator-*-py3-none-any.whl
```

列出 Python 包文件列表：

```bash
pip show geekcamp-calculator -f
```

终端输出：

## 使用方法

获取命令行工具执行路径：

```bash
python -c "import site; print('%s/bin/pycalculator' % site.USER_BASE)"
```

终端输出：

    ~/.local/bin/pycalculator

### 运行

```bash
~/.local/bin/pycalculator
```

分别输入 `1+1==2;`、`1+1=2;`

操作演示：
