## Overview
`python-brewer` is a command-line utility (written in Python) to help with
generating formula templates for [Homebrew](http://brew.sh) 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](https://github.com/Homebrew/brew/blob/master/docs/Python-for-Formula-Authors.md)
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):

```bash
> pip install python-brewer
```

## Basic Usage
As a simple example, we'll generate a base template for
[Statik](https://getstatik.com) - the static web site generator.
The first step is to install the package into your virtual environment:

```bash
> 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**.

```bash
> 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`:

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

desc "Python-based, generic static web site generator aimed at developers"
  homepage "https://getstatik.com"

Of course, I've since added the original `bottle` block for the
script and the package's unit tests. See
[this commit](https://github.com/thanethomson/homebrew-core/commit/b30f8a8f1aa55e15200e9862d90818ff4b8c1947)
and [statik.rb](https://github.com/Homebrew/homebrew-core/blob/master/Formula/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](https://github.com/tornadoweb/tornado/blob/master/setup.py).

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:

```ruby
  depends_on :python if MacOS.version <= :snow_leopard
```

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

```ruby
  depends_on :python3
```

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