sourcepp

Several modern C++20 libraries for sanely parsing Valve formats, rolled into one big repository.

Included Libraries

(*) Many text-based formats in Source are close to (if not identical to) KeyValues v1, such as VDF, VMT, and VMF.

(†) The MDL parser is not complete. It is usable in its current state, but it does not currently parse more complex components like animations. This parser is still in development.

Special Thanks

• steampp is based on the SteamAppPathProvider library by @Trico Everfire and Momentum Mod contributors.
• vpkpp's GCF parser was contributed by @bt and @ymgve.
• vpkpp's WAD3 parser was contributed by @ozxybox.
• vtfpp's write support is based on work by @Trico Everfire.

A list of projects using the sourcepp parser set. If you'd like to see your project here, make a PR!

• VPKEdit: An open source MIT-licensed tool that can create, extract from,
  preview the contents of and write to several pack file formats. A CLI application is bundled with the program which replicates
  the functionality of Valve's vpk.exe.
• GodotSource: A work-in-progress set of bindings to connect the sourcepp
  libraries to Godot. Allows GDScript to work with the libraries, and allows Godot to directly load Source engine assets from
  a user project or from installed Source games.
• Verifier: A small program that can build an index of a game's files, and validate
  existing files based on that index. Think Steam's "Verify integrity of game files" option, but without actually overwriting any
  files. sourcepp is used to parse Steam depot configs, as well as enable indexing the contents of VPKs.
