A Python wrapper for the JDK unpack200 utility
A Python wrapper for the JDK unpack200 utility.
The unpack200.unpack function takes three parameters:
- infile: string, full path to the pack200 file to extract
- outfile: string, full path to the jar file you'd like to extract to
- remove_source: bool (optional, default False), whether to remove the pack200 file specified in <infile> after extraction is complete
import unpack200 unpack200.unpack( r"C:\path o\packfile", r"C:\path o\outfile" )
Setup.py is currently only set up for Windows at the moment - feel free to contribute a Linux or Mac PR!
To build, first download and extract the following dependencies to your PC:
- Java JDK source code, e.g. from: https://github.com/dmlloyd/openjdk
- Java JDK built
python3 setup.py build
It will ask you two questions, enter a full path into both, e.g:
Where is the JDK source located? C:\JDK\src Where is the JDK include located? C:\Program Files\Java\jdk1.8.0_131\include
It will attempt to derive the correct locations for everything from these paths, and should build the extension.
Found an issue? Please report it either in the issues section of this repo, or to the developers of JDK. Any fix PRs would be welcome!
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
