# SLS Python

This directory contains a minimal Python project skeleton intended to reimplement
functionality from the C `SLS` project found at the repository root.

Layout
- `src/sls/` — Python package with module skeletons: `lexer`, `parser`, `interpreter`, `builtin`, `repl`, and `cli`.
- `tests/` — pytest tests (start with `test_import.py`).
- `pyproject.toml` — project metadata and `sls` console script entrypoint.
- `requirements-dev.txt` — developer/test tools.

Quick start

Create a venv and install editable package + dev requirements:

```bash
python -m venv .venv
source .venv/bin/activate
pip install -e SLS_Python
pip install -r SLS_Python/requirements-dev.txt
```

Run tests:

```bash
pytest -q
```

Run the REPL:

```bash
sls repl
```

Next steps (suggested)
- Port `lexer.c` to `src/sls/lexer.py` and add comprehensive tokenization tests.
- Port `parser` and `interpreter` incrementally, keeping tests for parity.
- Add CI (GitHub Actions) and type checking (`mypy`).

If you want, I can now:
- Run the tests in this environment (if you want me to configure the Python env), or
- Start porting a specific module from the C implementation (lexer is a good first target).
