FL Studio Python API Stubs

This project contains function definitions to provide intellisense while working on scripts for FL Studio's Python API, as well as a partially-complete model of FL Studio, which allows for scripts to be tested outside of FL Studio.

This repo is archived

Image-Line has officially adopted my API stubs, and you can check out a (significantly-improved) version over on their GitHub page. It's still open-source, and will be receiving far more maintenance than I had time to give for this when it was a hobby project.

Upgrading to Image-Line's stub library

All you need to do is update your dependencies - it's published under the same name.

Online Reference

The documentation is also available as an online reference.

Installation

To avoid module conflicts with other Python projects, it is recommended that you install this script in a virtual environment by following these instructions in the official Python documentation.

After activating the environment in your editor, you can install the stub modules by running the command pip install FL-Studio-API-Stubs on Windows or pip3 install FL-Studio-API-Stubs on MacOS or Linux.

The Small Print

A couple of notes regarding this repo.

This Documentation isn't Complete

Although the stubs are mostly complete, there are a few functions where I don't fully understand how they work. These functions have a HELP WANTED: label in their documentation. If you happen to know how to use one, I'd love it if you helped out by improving the documentation! I may also have incorrect definitions for some functions. Please create an issue if you find anything incorrect.

Differences to the Official Implementation

A small number of tweaks have been made to these stubs in order to ease code writing. These shouldn't have any functional impact on the behavior of the API compared to the implied behavior from the stubs, but should help clarify some properties of certain functions.

• Functions where parameters or returns are boolean by nature are listed as using a bool type, even though the implementation uses the integers 0 and 1. This change should help to describe the context in which the functions should be called when writing scripts, which in a language like Python is far more important than the actual implementation of the functions.

Development

Dependencies for this project are managed using Poetry. You'll need to install Poetry to develop it.

To install the required dependencies, run poetry install.
