Python module for extracting version from the string or directory name

Extract Version

Python module for extracting version from the string or directory name. Could make use for creating an inventory of installed versions of a particular application or finding the latest installed version.

The module offers the following functionality:

• Fetching version string from the string or name of the directory
• Validating version string
• Sorting config and application directories that contain versions in its name

Examples:

1. We fetch version 2020.1.0 from string PyCharm-2020.1.0, or version 1.0 from my_program_v1.0

• AppVersion.Major.Minor version format

extract_version(version_string="PyCharm-2020.1.0")
> "2020.1.0"

• Major.Minor version format

extract_version(version_string="my_program_v1.0")
> "1.0"

2. Sort directories by the version of application

sort_versions(["PyCharm-2018.1.2", "PyCharm-2018.2.0", "PyCharm-2020.1.0"])
> ["PyCharm-2018.1.2", "PyCharm-2018.2.0", "PyCharm-2020.1.0"]

3. In edge cases with more than one pattern present, e.g. PyCharm-2018.1.2-windows-10.0, we should provide a clue where the version should be extracted from, in a form of a pattern-regex, e.g.PyCharm-(.*)-windows-10.0 The call of such function may look like this:

extract_version(version_string='PyCharm-2018.1.2-windows-10.0', pattern='PyCharm-(.*)-windows-10.0')
> "2018.1.2"

4. Create an inventory of installed versions of a particular application

application_path = "C:/Users/user/AppData/Local/JetBrains/PyCharm"
pycharm_versions = available_versions(versions_path=application_path)
> {"2018.1.2": "PyCharm-2018.1.2", "2018.2.0": "PyCharm-2018.2.0", "2020.1.0": "PyCharm-2020.1.0"}
