wheel-inspect examines Python wheel files & *.dist-info directories and outputs various information about their contents as JSON-serializable objects. It can be invoked in Python code as:

from wheel_inspect import inspect_wheel

output = inspect_wheel(path_to_wheel_file)

or from the command line with the wheel2json command.

Installation

wheel-inspect requires Python 3.7 or higher. Just use pip for Python 3 (You have pip, right?) to install wheel-inspect and its dependencies:

python3 -m pip install wheel-inspect

Example

$ wheel2json wheel_inspect-1.0.0.dev1-py3-none-any.whl

API

wheel_inspect.DIST_INFO_SCHEMA

A JSON Schema for the structure returned by inspect_dist_info_dir(). It is the same as WHEEL_SCHEMA, but without the "filename", "project", "version", "buildver", "pyver", "abi", "arch", and "file" keys.

wheel_inspect.WHEEL_SCHEMA

A JSON Schema for the structure returned by inspect_wheel(). This value was previously exported under the name "SCHEMA"; the old name continues to be available for backwards compatibility, but it will go away in the future and should not be used in new code.

wheel_inspect.inspect_dist_info_dir(dirpath)

Treat dirpath as a *.dist-info directory and inspect just it & its contents. The structure of the return value is described by DIST_INFO_SCHEMA.

wheel_inspect.inspect_wheel(path)

Inspect the wheel file at the given path. The structure of the return value is described by WHEEL_SCHEMA.

Previous versions of wheel-inspect provided a parse_wheel_filename() function. As of version 1.5.0, that feature has been split off into its own package, wheel-filename. wheel-inspect continues to re-export this function in order to maintain API compatibility with earlier versions, but this will change in the future. Code that imports parse_wheel_filename() from wheel-inspect should be updated to use wheel-filename instead.

Command

wheel2json [<path> ...]

wheel-inspect provides a wheel2json command (also accessible as python -m wheel_inspect) that can be used to inspect wheels and *.dist-info directories from the command line. Each path passed to the command is inspected separately (treated as a *.dist-info directory if it is a directory, treated as a wheel file otherwise), and the resulting data is output as a pretty-printed JSON object. (Note that this results in a stream of JSON objects with no separation when multiple paths are given.)
