rose

"""A version by any other name would be just as sweet."""

A small library for keeping your version up-to-date easily & everywhere.

The pain of having to update your setup.py, your Sphinx conf.py, your __init__.py & everything else on every release of your Python package sucks. Make your life easier (& very semver!)

By putting your version number in a top-level VERSION file & using this library, you can cut duplication & tedious manual work without having to lean on crazy import hacks.

Inspired by crazy discussion with George Hickman (ghickman) at PyCon 2013.

Requirements

• Python 2.5+

Usage

To start, first install rose (see below). Then, push your version number into it's own file (typically called VERSION):

$ echo '1.0.0-beta' > VERSION

Update your setup.py to look like:

# ...

import rose

setup(
    name='your_package_name_here',
    # UPDATE THIS LINE!
    version=rose.load_version('VERSION'),
    # The usual follows...

Then update your __init__.py:

# Whatever is there, then...

import os
import rose

# If you don't care about being cross-platform, you can just pass a simple
# path instead.
VERSION_FILE = os.path.join(os.path.dirname('VERSION'))
__version__ = rose.build_version('your_package_name_here', rose.load_version(VERSION_FILE))

And if you're documenting with Sphinx, you can update your conf.py with:

# ADD THIS!
import rose
RELEASE_VERSION = rose.load_version('../VERSION')
SHORT_VERSION = RELEASE_VERSION.split('-')[0]

# The version info for the project you're documenting, acts as replacement for
# |version| and |release|, also used in various other places throughout the
# built documents.
#
# The short X.Y version.
version = SHORT_VERSION
# The full version, including alpha/beta/rc tags.
release = RELEASE_VERSION

Installation

Using pip, simply run:

pip install rose
