* replace pkg_resources with importlib.metadataDoug Hellmann2020-07-121-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Importing pkg_resources has a side-effect of scanning every installed distribution on sys.path to load the metadata, especially the entry points defined in the packages. This can have a significant launch-time cost for command line applications when there are a lot of distributions to scan. Since cmd2 is only using pkg_resources to find the version of the installed package, pkg_resources can be replaced with importlib.metadata. The implementation in the new library is significantly faster because it goes immediately to the metadata file for the requested distribution, instead of scanning all of them. There are also no import-time side-effects. importlib.metadata is a new standard library module starting with python 3.8. For earlier versions, a compatible library has been released to PyPI as 'importlib_metadata'. This change adds the new dependency with a qualifier so that it is only applied to older versions of python, and then updates the places that were importing pkg_resources to look for the different versions of the new library instead. The documentation configuration is changed to import cmd2 itself to get its version, since the package has to be installed for the metadata to be available anyway.
