PyScaffold - Easy setup of a Python project with a bliss#python · · Peter Hoffmann
PyScaffold helps you to easily setup a new Python project.
Setting up a Python project is usually quite boring, cumbersome and definitely
repetitive. This is exactly where PyScaffold excels.
You create the structure of your package with package folder, test
and docs folder, generate the
__init__.py files and setup.py for starters.
After that it’s all about tweaking your configuration files like
you are using git (who isn’t these days?),
.coveragerc for your coverage
reports, conf.py for your Sphinx documentation and of course you want automatic
PEP8 checks… you see where this is going. Before you have coded the first line
of your actual project, you spent hours to adjust and configure the nuts and
bolts of your project’s scaffold. But there is help, and since we want to put
up a scaffold for our Python project, it is naturally called PyScaffold!
PyScaffold is easy to use and lets you set up a Python project in about 5
seconds. You install it with:
pip install pyscaffold
which takes about 3 seconds and create your project named
my_project in about 2 seconds:
This neat little command creates a folder my_project with the usual project
layout of a Python project. You’ll have a my_project package folder inside as
well as docs and tests folders and the files
LICENSE.txt. So far, unimpressive, you might say but here comes
the cool part. All configuration of your project is done in
setup.py. There you can change all settings related to your package like the
author, url, license and you can even configure Python console scripts. Ever
wanted to distribute non-Python data files in your Python package? Yep, it is a
pain to fiddle with
MANIFEST.in and the various options of the setup command.
But not so with PyScaffold! Within
setup.cfg we can just name additional data
files and they will be included in our distribution.
By the way, building your package just works out of the box with
setup.py sdist. Since the my_project folder is already an initialized git
repository and git is used to retrieve a PEP440 compliant version number, a
package is built whose version number reflects the current git commit or tag.
In practice that means, no longer you need to specify and change a version
string inside your package, all that information is just taken from your git
history and your tags. Responsible for this magic is a sophisticated setup.py
that provides a lot of comfort features. You can print the current version with
python setup.py version, run your unit tests with
python setup.py test, build
your documentation with
python setup.py docs and so forth. And that’s not even
all, there are many more goodies in PyScaffold.
Let’s say our project is called Scikit-Brain but we want the package itself called skbrain. Additionally we want a basic configuration for Travis as well as automatic PEP8 and error checks with the help of pre-commit. The whole project should be new-BSD licensed. With PyScaffold that’s just:
putup Scikit-Brain -p skbrain --license new-bsd --with-pre-commit --with-travis
