Overview

pyroma

Pyroma rhymes with aroma, and is a product aimed at giving a rating of how well a Python project complies with the best practices of the Python packaging ecosystem, primarily PyPI, pip, Distribute etc, as well as a list of issues that could be improved.

The aim of this is both to help people make a project that is nice and usable, but also to improve the quality of Python third-party software, making it easier and more enjoyable to use the vast array of available modules for Python.

It's written so that there are a library with methods to call from Python, as well as a script, also called pyroma.

It can be run on a project directory before making a release:

$ pyroma .

On a distribution before uploading it to the CheeseShop:

$ pyroma pyroma-1.0.tar.gz

Or you can give it a package name on CheeseShop:

$ pyroma pyroma

Giving it a name on CheeseShop is the most extensive test, as it will test for several things isn't otherwise tested.

In all cases the output is similar:

------------------------------
Checking .
Found pyroma
------------------------------
The packages long_description is quite short.
------------------------------
Final rating: 9/10
Cottage Cheese
------------------------------

Tests

This is the list of checks that are currently performed:

  • The package should have a name, a version and a Description. If it does not, it will recieve a rating of 0.
  • The version number should be a string. A floating point number will work with distutils, but most other tools will fail.
  • The version number should comply to PEP386.
  • The long_description should be over a 100 characters.
  • Pyroma will convert your long_description to HTML using Docutils, to verify that it is possible. This guarantees pretty formatting of your description on PyPI. As long as Docutils can convert it, this passes, even if there are warnings or error in the conversion. These warnings and errors are printed to stdout so you will see them.
  • You should have a the following meta data fields filled in: classifiers, keywords, author, author_email, url and license.
  • You should have classifiers specifying the sypported Python versions.
  • If you are using setuptools or distribute you should specify zip_safe, as it defaults to "true" and that's probably not what you want.
  • If you are using setuptools or distribute you can specify a test_suite to run tests with 'setup.py test'. This makes it easy to run tests for both humans and automated tools.
  • If you are checking on a PyPI package, and not a local directory or local package, pyroma will check the number of owners the package has on PyPI. It should be three or more, to minimize the "Bus factor", the risk of the index owners suddenly going off-line for whatever reason.
  • If you are checking on a PyPI package, and not a local directory or local package, Pyroma will look for documentation for your package at pythonhosted.org and readthedocs.org. If it can't find it, it prints out a message to that effect. However, since you may have documentation elsewhere, this does not affect your rating.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
