This should run on any version of Python 3 after/including 3.10; packaging will need to be installed (a requirements.txt file is included in this repo) as distutils is deprecated.
Run ./build.sh with no additional arguments to create a compressed zipapp version of this utility; please note the default Python interpreter and shebang used is /usr/bin/env python3, if a more specific shebang needs to be used, run ./build.sh /new/shebang/path, for example: ./build.sh /usr/local/bin/python3. This will generate a new "build" in ./dist/zipapp/usr/local/bin/custom/.
This tool is provided 'as is', if an application is prompting to install a package that loopdown has installed, please use this issue form.
Please note, responses to issues raised may be delayed.
Feature requests can be made, but this project has been deliberately kept to a very defined scope of behaviour/capability.

loopdown v1.0.20230726, licensed under the Apache License Version 2.0
On a Mac with any of the three audio applications installed, loopdown inspects the application bundle for a property list file that contains metadata about the audio contents for that version of the application, and based on this information and the options provided to the utility, will either install or update the necessary packages.
If the --pkg-server argument is supplied with a web server as the parameter, loopdown will use that URL in place of the Apple CDN. The paths to each package must be an exact mirror of the Apple paths (this can be done by using the --create-mirror [path] argument and parameter on a standalone Mac).
For example, if mirroring from https://example.org, then the folder paths must match https://example.org/lp10_ms3_content_2013/[package files] and/org https://example.org/lp10_ms3_content_2016/[package files].
If the --cache-server argument is supplied with an Apple caching server URL as the parameter, loopdown will use that caching server just the same as if the audio application itself was downloading the audio content.
In this particular scenario, if you are installing the audio content packages on multiple clients, best practice is to do this one one Mac first, before proceeding with additional clients.
A mirror copy of the audio content files can be created on a standalone Mac, it is preferable to have the relevant audio applications installed, but it is not required.
If the applications are installed, the mirror can be created with:
> ./loopdown -m -o --create-mirror [path] -a [app]
If the applications are not installed, the mirror can be created with:
> ./loopdown -m -o --create-mirror [path] -p [plist]
To find the relevant property lists for use with the -p/--plist argument, use the --discover-plists argument.
There are a number of command line arguments that are hidden from the -h/--help argument by default, these are used for configuring default parameters, but if necessary these default parameters can be overridden; use the --advanced-help argument to show these options.
It is recommended to leave these options as their default settings.
By default, logs are stored in /Users/Shared/loopdown. If you need more detailed logging than the standard level, use the --log-level [level] argument and parameter.
