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

Installation

The package can be installed from pip

pip install extract-version

There are archives of previous releases available on Github with the mirror on AWS

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"}
