PythonUnpack200

A Python wrapper for the JDK unpack200 utility.

Usage

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 after extraction is complete

For example:

import unpack200

unpack200.unpack(
	r"C:\path	o\packfile",
	r"C:\path	o\outfile"
)

Building

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

run:

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.
