Python environment comparison tool.
Python environment comparison tool. Maximized for compatibility between versions 2.6 to 3.7, pypy, operating systems, distributions, and forks! Virtualenv, pyenv, pyvenv, conda, system!
From the command line, to get information on the current environment:
python -m pyenvdiff.info
Serialize the information to a file…
python -m pyenvdiff.info my_environment.yaml
Switch to another environment (you’ll need pyenvdiff installed in both)
python -m pyenvdiff.compare my_environment.yaml
Or compare two from any environment
python -m pyenvdiff.compare my_environment.yaml my_other_environment.yaml
>>> from pyenvdiff import Environment >>> e = Environment() >>> e.to_yaml('my_env.yaml') >>> o = Environment.from_yaml('other_env.yaml') >>> e == o True >>> print(e) ... # prints a dump of the environment details >>> from pyenvdiff import EnvironmentDiff >>> ed = EnvironmentDiff(e, o) >>> print(ed) ... # prints a diff of the two environments
An alpha-level web-based comparison tool is available to browse and compare. PyEnvDiff ships with a default API Key, which is severly throttled. Some jerk is likely to abuse it, but until then, try it out.
Get a free personal API Key.
Install your own API key by setting a global environment variable “PYENVDIFF_API_KEY”, set to the api key.
From any two python interpreters, you can run:
python -m pyenvdiff.post --email email@example.com
python -m pyenvdiff.post --domain your.website.com
…for more optional meta data fields:
python -m pyenvdiff.post -h
Which should output… something like the below, (once for each environment you run it).
Posting environment information to https://osa.pyenvdiff.com Using API KEY: ... Successful POST, use SHA XXXX for reference or comparison.
Then, use that SHA to fill in the link below:
After you’ve collected another SHA from another environment…use the link format below, where XXXX and YYYY are two relevant SHAs.
Sooo much room for activities!
- Compare dev, test & prod!
- Works on my machine, strange it doesn’t work on yours
- Confirming deployments
- Auditing user desktops, servers, research environments & ecosystems
- Filing (or requesting) bug reports
There are no manditory, nor automatically installing, dependencies.
pip install pyenvdiff
OR just copy & paste pyenvdiff anywhere on PYTHONPATH
There is one optional dependency. The core functionality doesn’t use it. It’s only needed for more advanced HTML-based comparison.
pip install ghdiff
Under the hood
- Zero dependency, pure-python, harmless pip install pyenvdiff or copy anywhere on PYTHONPATH.
- As-needed import statements, to maximize compatibility across python flavours.
- Favours compatible python-code over succinct or newer-style python-code
- Free software: BSD license
- Documentation: https://pyenvdiff.readthedocs.io.
- First release on PyPI.
