vpk 1.4.0

Library for working with Valve Pak files

VPK is Valve’s file format for storing game assets. Pythonic access to VPK files and their contents together with a cli tool.

Works on: python2.7, python3.4+, pypy, and pypy3

Install

You can grab the latest release from https://pypi.python.org/pypi/vpk or via pip

pip install vpk

Quick start

The VPK instance is iterable in the standard ways and produces paths to files

import vpk

pak1 = vpk.open("/d/Steam/steamapps/common/dota 2 beta/dota/pak01_dir.vpk")

for filepath in pak1:
    print filepath

Reading a specifc file is done by passing the file path to get_file() method, which returns a VPKFile instance, which acts as a regular file instance. Writting is not possible.

pakfile = pak1.get_file("scripts/emoticons.txt")
pakfile = pak1["scripts/emoticons.txt"]
print pakfile.read().decode('utf-16le')

-------------------------------------------------
"emoticons"
{
    // An ID of zero is invalid

    "1"
    {
        "image_name" "wink.png"
        "ms_per_frame" "100"
...

Saving a file is just as easy.

pakfile.save("./emoticons.txt")

The module supports creating basic VPKs. Multi archive paks are not yet supported.

newpak = vpk.new("./some/directory")
newpak.save("file.vpk")

pak = newpak.save_and_open("file.vpk")
