## Getting Started

### Cloning pedalbaord

To get your environment set up to build `pedalboard`, you'll need a working C++ compiler on your machine (`xcode-select --install` on macOS should do it). Try:

```shell
git clone --recurse-submodules --shallow-submodules [email protected]:spotify/pedalboard.git
cd pedalboard
pip3 install pybind11
pip3 install .
```

### Virtual environment

In order to not pollute your system python environement it is recommended that you use a virtual environment when building `pedalbaord`. Refer to INSTALLATION.md for instructions on how to set up a virtual environment

### Building `pedalboard`

To compile a debug build of `pedalboard` that allows using a debugger (like gdb or lldb), use the following command to build the package locally and install a symbolic link for debugging:
```shell
python3 setup.py build develop
python3 -m pip install -ve .
```

Then, you can `import pedalboard` from Python (or run the tests with `tox`) to test out your local changes.

By default, [all `.cpp` and `.mm` files in the `pedalboard` directory (or subdirectories)](https://github.com/spotify/pedalboard/blob/master/setup.py#L129) will be automatically compiled by `setup.py`.
