PyPI PyPI

Overview

python-brewer is a command-line utility (written in Python) to help with generating formula templates for Homebrew from installed Python packages. The aim is not to generate perfect, ready-to-go Homebrew formulae out of the box: the aim is to generate a template for you, taking some of the harder slog work out of the process.

Primarily, it takes an installed package, finds all of its installed dependencies, and generates a template containing resource references to all of these dependencies (as per the installed versions). It also automatically computes the SHA256 hashes of all of the packages by downloading their source distributions from PyPI.

See Homebrew's Python for Formula Authors guide for more details on submitting Python-based formulae for Homebrew.

Requirements

In order to install python-brewer, you will need:

  • Python 2.7+ or Python 3.5+
  • pip

Installation

Installing via PyPI (install into a virtual environment please):

> pip install python-brewer

Basic Usage

As a simple example, we'll generate a base template for Statik - the static web site generator. The first step is to install the package into your virtual environment:

> pip install -U statik

The next step is to use the pybrew command, provided by python-brewer, to generate the Homebrew formula template. In this case, at the time of this writing, I was generating the formula for v0.14.2 of Statik.

> pybrew \
    # The name of the formula
    -n "Statik" \
    # A description for the formula
    -d "Python-based, generic static web site generator aimed at developers" \
    # Project homepage
    -H https://getstatik.com \
    # HEAD of Git repo
    -g https://github.com/thanethomson/statik.git \
    # Latest release of the package
    -r https://github.com/thanethomson/statik/archive/v0.14.2.tar.gz \
    # Name of the Python package
    statik \
    # Output file to which to write the template
    statik.rb

At the time of this writing, the following file was generated by pybrew:

class Statik < Formula
  include Language::Python::Virtualenv

  desc "Python-based, generic static web site generator aimed at developers"

Of course, I've since added the original bottle block for the script and the package's unit tests. See this commit and statik.rb in homebrew-core for more details.

Python 2 or 3?

While python-brewer runs well on Python 2.7+ and Python 3.5+, it's important to note that sometimes your dependencies will be different based on which Python version you're running, and based on the nature of your dependencies. Sometimes, certain packages include different dependencies when running Python 3, e.g. Tornado.

As such, python-brewer automatically changes the Python dependency based on the detected Python version. In the above package for Statik, I ran pybrew with Python 2 and, as such, automatically added the line:

  depends_on :python if MacOS.version <= :snow_leopard

If I had run it with Python 3, it would have added the following line instead:

  depends_on :python3

This will, of course, cause Homebrew to attempt to install its own Python 3 distribution for your package.
