Build from Source

raydar is written in Python and Javascript. While prebuilt wheels are provided for end users, it is also straightforward to build raydar from either the Python source distribution or the GitHub repository.

Make commands

As a convenience, raydar uses a Makefile for commonly used commands. You can print the main available commands by running make with no arguments

> make

build                          build the library
clean                          clean the repository
fix                            run autofixers
install                        install library
lint                           run lints
test                           run the tests

Prerequisites

raydar has a few system-level dependencies which you can install from your machine package manager. Other package managers like conda, nix, etc, should also work fine.

Clone

Clone the repo with:

git clone https://github.com/Point72/raydar.git
cd raydar

Install NodeJS

Follow the instructions for installing NodeJS for your system. Once installed, you can install pnpm with:

npm install --global pnpm

Install Python dependencies

Python build and develop dependencies are specified in the pyproject.toml, but you can manually install them:

make requirements

Note that these dependencies would otherwise be installed normally as part of PEP517 / PEP518.

Build

Build the python project in the usual manner:

make build

Lint and Autoformat
