# Contributing to LanceDB Python
|
|
|
|
This document outlines the process for contributing to LanceDB Python.
|
|
For general contribution guidelines, see [CONTRIBUTING.md](../CONTRIBUTING.md).
|
|
|
|
## Project layout
|
|
|
|
The Python package is a wrapper around the Rust library, `lancedb`. We use
|
|
[pyo3](https://pyo3.rs/) to create the bindings between Rust and Python.
|
|
|
|
* `src/`: Rust bindings source code
|
|
* `python/lancedb`: Python package source code
|
|
* `python/tests`: Unit tests
|
|
|
|
## Development environment
|
|
|
|
To set up your development environment, you will need to install the following:
|
|
|
|
1. Python 3.9 or later
|
|
2. Cargo (Rust's package manager). Use [rustup](https://rustup.rs/) to install.
|
|
3. [protoc](https://grpc.io/docs/protoc-installation/) (Protocol Buffers compiler)
|
|
|
|
Create a virtual environment to work in:
|
|
|
|
```bash
|
|
python -m venv venv
|
|
source venv/bin/activate
|
|
pip install maturin
|
|
```
|
|
|
|
### Commit Hooks
|
|
|
|
It is **highly recommended** to install the pre-commit hooks to ensure that your
|
|
code is formatted correctly and passes basic checks before committing:
|
|
|
|
```bash
|
|
make develop # this will install pre-commit itself
|
|
pre-commit install
|
|
```
|
|
|
|
## Development
|
|
|
|
Most common development commands can be run using the Makefile.
|
|
|
|
Build the package
|
|
|
|
```shell
|
|
make develop
|
|
```
|
|
|
|
Format:
|
|
|
|
```shell
|
|
make format
|
|
```
|
|
|
|
Run tests:
|
|
|
|
```shell
|
|
make test
|
|
make doctest
|
|
```
|
|
|
|
To run a single test, you can use the `pytest` command directly. Provide the path
|
|
to the test file, and optionally the test name after `::`.
|
|
|
|
```shell
|
|
# Single file: test_table.py
|
|
pytest -vv python/tests/test_table.py
|
|
# Single test: test_basic in test_table.py
|
|
pytest -vv python/tests/test_table.py::test_basic
|
|
```
|
|
|
|
To see all commands, run:
|
|
|
|
```shell
|
|
make help
|
|
```
