Package: pyenvdiff
PyEnvDiffPython environment comparison tool.  Maximized for compatibility between versions 2.6 to 3.8, pypy,
operating systems, distributions, and forks!  Virtualenv, pyenv, pyvenv, conda and system!via Command-LineFrom the command line, to get information on the current environment:python -m pyenvdiff.infoSerialize the information to a file…python -m pyenvdiff.info my_environment.jsonSwitch to another environment (you’ll need pyenvdiff installed in both)python -m pyenvdiff.compare my_environment.jsonOr compare two from any environmentpython -m pyenvdiff.compare my_environment.json my_other_environment.jsonvia Hub-Based CompareAn HTTP-based service comes with pyenvdiff, all without dependencies (thanks to a copy of bottle).  It stores environment
information in RAM, for as long as it runs.  This service should be considered alpha-stage.To launch the built-in hub (server):python -m pyenvdiff.hubThen navigate in your browser to the URL it gives you to see the menu of available options.  Before you send information
about other environments on the same machine, your options will be limited to just viewing the server’s environment.Samples of theHub Landing Pageand theEnvironment Information Pageillustrate the features.From one or more other environments run:python -m pyenvdiff.post_to_hubA URL will be displayed to view environment information from any machine on the same network.Navigate back to the base URL, you’ll see more options to compare the two environments.A Sample of theEnvironment Diff Pageillustrate what the diff can do (if`ghdiff`is installed for the hub).Programmatic Usage>>>frompyenvdiffimportEnvironment>>>e=Environment()>>>e.to_file('my_env.json')>>>o=Environment.from_file('other_env.json')>>>e==oTrue>>>print(e)...# prints a dump of the environment details>>>frompyenvdiffimportEnvironmentDiff>>>ed=EnvironmentDiff(e,o)>>>print(ed)...# prints a diff of the two environmentsSooo much room for activities!Compare dev, test & prod!Works on my machine, strange it doesn’t work on yoursConfirming deploymentsAuditing user desktops, servers, research environments & ecosystemsFiling (or requesting) bug reportsInstallationThere are no mandatory, nor automatically installing, dependencies.  There are optional dependencies which increase.pip install pyenvdiffOR just copy & paste pyenvdiff anywhere on PYTHONPATHThere is one optional dependency.  The core functionality doesn’t use it.  It’s only needed for pretty HTML-based comparisons via the web.pip install ghdiffUnder the hoodRobust and organized object model collects and serializes environment information.Zero dependency, pure-python, harmless install!  Simplypip install pyenvdiffor copy anywhere on PYTHONPATH.As-needed import statements, to maximize compatibility across python flavours.Favours compatible python-code over succinct or newer-style python-codeFree software: BSD licenseDocumentation:https://pyenvdiff.readthedocs.io.CreditsThis package was started withCookiecutterand theaudreyr/cookiecutter-pypackageproject template.History0.3.0 (2018-11-18)Add bottle-based Hub for P2P ComparisonsAdded Python 3.8 SupportFixed bug impacting Ubuntu 18 [GH Issue #15]Removed documented support for Third-party API-enabled comparisonsEnhanced the SysPrefix collector.
