Gem Version

SteamCodec is a library for working with different Steam client (and Source engine) file formats.

Currently supported formats:

  • KeyValues
  • VDF (Valve Data Format)
  • ACF (ApplicationCacheFile)

PKV (packed KeyValues) isn't supported yet.


Add this line to your application's Gemfile:

gem 'steam_codec'

And then execute:


Or install it yourself as:

gem install steam_codec


gem insensitive_hash


require 'steam_codec'"appmanifest_220.acf") do |file|
    acf = SteamCodec::ACF::loadFromFile(file)
    puts acf.UserConfig.Name


YARD with markdown is used for documentation (redcarpet required)


RSpec and simplecov are required, to run tests just rake spec code coverage will also be generated
