How can I use the unitypackage without unity?
Hi, I want to use a xml file from a unitypackage file .But I don't want to use the unity to extract the unitypackage file.Is there another way to extract unitypackage file? Thanks in advance!
I made a simple Python library that will do this because all of the projects linked seemed to be broken.

It's true that a .unitypackage is just a .tar.gz, but it also has an internal structure whereby there are folders that each hold multiple pieces representing one file. The above Python script will extract the entire .unitypackage as normal files.
As @KulestarUK pointed out, .unitypackage files are indeed .tar.gz files :D
You can list the files like this:
tar -ztvf GooglePlayGamesPlugin-0.9.34.unitypackage
...
./01dde458421cf400394d2f715db9e194/asset ./01dde458421cf400394d2f715db9e194/asset.meta ./01dde458421cf400394d2f715db9e194/pathname ./00e67e97029f64d44904d85583893fe9/asset ./00e67e97029f64d44904d85583893fe9/asset.meta ./00e67e97029f64d44904d85583893fe9/pathname ./00e08ce5b0e2044329c76dcf32fcec96/asset ./00e08ce5b0e2044329c76dcf32fcec96/asset.meta ./00e08ce5b0e2044329c76dcf32fcec96/pathname
Sadly, it's a bit sad and not very verboze. I didn't need to actually extract these files, but I wanted a clear text list of all the files that would be added (So I can easily uninstall a package).
From above output, hard to quickly and easily get a clear text list of the files without reading all of the pathname files. After some command line fu, I managed to write the following command:
tar -axf GooglePlayGamesPlugin-0.9.34.unitypackage --wildcards --no-anchored '*pathname*' --to-command="echo '' && cat"
It basically extract files that has pathname in their name, read them and pass them to echo '' && cat which prints a newline and read the file.
Output looks like this:
...
Assets/GooglePlayGames/Platforms/IOS Assets/Plugins/iOS/GPGSAppController.mm Assets/GooglePlayGames/Platforms/Native/PInvoke/BaseReferenceHolder.cs Assets/GooglePlayGames/Platforms/Native/NativeQuestClient.cs Assets/GooglePlayGames/Platforms/Native/ConversionUtils.cs

As @sharp911 mentionned, you may also give bradgearon/unity-3d-package-extract a try
Actually if you want to uninstall a package you should use the AssetIDs ins$$anonymous$$d of the filenames. Files might have been moved / renamed inside the Unity project. The assetID never changes (except when you delete the meta file).
It's true that you can extract it as a .tar.gz but you have to do some file manipulation to get the original file, really annoying if you need an entire large package as it would normally exist in the filesystem.
I wrote this Python script to take care of that https://github.com/Cobertos/unitypackage_extractor
Not sure if it works, but here is a supposed option : http://forum.unity3d.com/threads/180080-Released-Open-Source-unitypackage-extractor-from-cmd-line
It's also worth pointing out that they're actually just .tar.gz files, so if you rename them you can extract the contents with familiar software too or build them yourself if needed. (They contain a bunch of folders, each of which contains a file called 'asset' which is the actual asset data, alongside various bits of meta and a file containing the original path).
