Python Brewer 0.3.0 | GitLocker.com Product

Description:

pythonbrewer 0.3.0

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

# TODO: Add your package's tests here
end
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.
