Installation
# apt-get install python python-dev python-virtualenv
Start a new project
Create a file called README
that describes your project to a human using reStructuredText.
Create a file called setup.py
that contains meta-data for your project. Include any dependencies in the install_requires
field.
#!/usr/bin/env python
import os
from setuptools import setup
def read(fname):
return open(os.path.join(os.path.dirname(__file__), fname)).read()
setup(
name='languageignition',
version='0.1.0',
description='Get started with a new language',
long_description=read("README"),
author='Michael Williamson',
author_url='mike@zwobble.org',
url='http://github.com/mwilliamson/language-ignition.com',
packages=['languageignition'],
install_requires=[
'requests>=1.0,<2.0',
],
license='BSD 2-Clause',
)
Create a file called test-requirements.txt
that contains test dependencies:
nose>=1.3,<2.0
mock>=1.0,<2.0
Initialise your project
Make sure you're at the root of your project, which should contain setup.py
Create a virtualenv if you haven't already:
$ virtualenv venv
$ venv/bin/pip install distribute --upgrade
Install your project and its dependencies into the virtualenv:
$ venv/bin/pip install -e .
Install test dependencies into the virtualenv:
$ venv/bin/pip install -r test-requirements.txt
Install a library
Let's assume we want to install requests.
Create a virtualenv if you haven't already:
$ virtualenv venv
$ venv/bin/pip install distribute --upgrade
Install the library in the virtualenv:
$ venv/bin/pip install requests
Install a command-line tool
Let's assume we want to install tox.
Create a virtualenv for that tool:
$ mkdir -p ~/apps
$ virtualenv ~/apps/tox
$ ~/apps/tox/bin/pip install distribute --upgrade
Install the tool in the virtualenv:
$ ~/apps/tox/bin/pip install tox
Run the tool:
$ ~/apps/tox/bin/tox
Optionally create a symlink in a directory that's on your $PATH
. Assuming ~/bin is on your path:
$ ln -s ~/apps/tox/bin/tox ~/bin
