Brew Python Resource Blocks

brew-python-resource-blocks is a Rust tool that generates Homebrew resource blocks for Python packages listed in a requirements.txt file. This tool fetches package information from PyPI and formats it into resource blocks that can be used in Homebrew formulae.

Features

• Reads a requirements.txt file and extracts package names and versions.
• Fetches package information from PyPI.
• Generates Homebrew resource blocks with URLs and SHA256 checksums.

Installation

To build the tool, you need to have Rust installed. You can install Rust using rustup.

# Clone the repository
git clone https://github.com/yourusername/brew-python-resource-blocks.git

# Change to the project directory
cd brew-python-resource-blocks

# Build the project
cargo build --release

Usage

To use the tool, run the following command, providing the path to your requirements.txt file:

cargo run -- path/to/requirements.txt

This will output the generated resource blocks to the console.

Example

Given a requirements.txt file with the following content:

# This file was autogenerated by uv via the following command:
#    uv export --format=requirements-txt
-e .
