A super-light weight python script that watches the list of currently installed packages on Mac OS and tracks changes overtime, notify user of changes in list of package id using Mac OS Notification (if set up using cron). It has no Python dependency outside of Python 3's standard modules. It relies on the pkgutil that comes with Mac OS.
You can run the run.py manually, ie:
python run.py
Each time it is executed, a list of packages will be write to file in the log/ directory, next time the run.py is executed again, it will compare the current list of packages against the one in the log direcotry from previous time, and then print out a report. A detailed list of packages installed and removed will be saved in the reports/ directory.
From Terminal:
crontab -e
and insert the following line:
* * * * * /PATH_TO_YOUR_PYTHON_/bin/python /PATH_TO_/pkg-watch/run.py --user
For debugging, you can use the following to print output of the python script:
* * * * * /.../bin/python /.../pkg-watch/run.py --user >> out.txt 2>&1
