A device information gatherer for Linux and macOS
Project description
# getdevinfo
This repository holds my new getdevinfo module. This module was originally integreted directly into the source code of Wine Autostart, DDRescue-GUI, and WxFixBoot, but has now been separated for ease of maintenance. Because it’s on GitLab (https://gitlab.com/hamishmb/getdevinfo) and on PyPI (the Python Package Index) (https://pypi.org/project/getdevinfo/), and released under the GPLv3+, this means other people can use it too.
Description of Package
A device information gatherer for Linux and macOS.
Working on both Linux and macOS, this script makes use of lshw, lvdisplay, and blkid (Linux), as well as diskutil (macOS) to get a comprehensive amount of disk information. This information is available in a structured dictionary for ease of use.
Features:
Uses the operating system's built-in tools to gather lots of helpful information about disks connected to the system. This is returned as a hierarchical python dictionary. For the full details on the format, read the documentation here: https://www.hamishmb.com/html/Docs/getdevinfo.php
Dependencies:
On Linux it requires lshw, blkid, lvdisplay, and blockdev to be installed. On Linux, you need the beautifulsoup4 (bs4), and lxml python packages to use this tool. On macOS, nothing beyond a standard python3.x install is required, but you still need bs4 and lxml if you want to install using the python wheel/through pip.
Building
Source Distribution
Run:
“python setup.py sdist”
Wheels
Make sure you’ve installed the “wheel” package:
“pip3 install wheel”
Universal Wheel
This is the recommended choice, though GetDevInfo no longer runs on Python 2 from version 1.0.7 onwards,
“python3 setup.py bdist_wheel –universal”
Pure Python Wheel
Not sure why you’d do this, but you can run:
“python3 setup.py bdist_wheel”
to acheive this if you want.
Distribution Packages
You can find these at https://www.launchpad.net/getdevinfo or https://www.hamishmb.com/html/downloads.php?program_name=getdevinfo.
Documentation
This can be found at https://www.hamishmb.com/html/Docs/getdevinfo.php.
Running directly from the command line
Run:
“sudo python3 -m getdevinfo.getdevinfo”
Or (v1.0.8 onwards):
“sudo python3 -m getdevinfo”
Running The Tests
These have to be run as the superuser, because low-level access to hardware is required to gather information.
The process for running these is the same on both Linux and macOS. Note that prior to version 1.0.7, GetDevInfo ran on Python 2 as well.
Without Coverage Reporting
Change directory to the getdevinfo subfolder, and run:
“sudo python3 ./tests.py”
With Coverage Reporting
Make sure you have installed Coverage.py using pip or your package manager.
Change directory to the getdevinfo subfolder, and run:
“sudo python3 -m coverage run –rcfile=../.coveragerc ./tests.py”
To run the tests. Then run:
“sudo python3 -m coverage report”
To see the report.
