Source Pretty Parsers

Several modern C++20 libraries for sanely parsing Valve formats.

Other Languages

Wrappers for libraries considered complete exist for C, C#, and/or Python, depending on the library. The C# wrappers can be found on NuGet in the sourcepp package. The Python wrappers can be found on PyPI in the sourcepp package.

Included Libraries

(*) These libraries are incomplete and still in development. Their interfaces are unstable and will likely change in the future. Libraries not starred should be considered stable, and their existing interfaces will not change much if at all. Note that wrappers only exist for stable libraries.

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

Anything using the sourcepp parser set that I know of, directly or indirectly.

These are only the tools and games using sourcepp that I know of. If you would like to be listed here, email me or join my Discord server, I'd love to hear from you!

Tools

• fgptool: A tool to crack the filepath hashes in The Orange Box PS3 file groups.
• fOptimizer: A GUI-based collection of tools written in Python for cutting down on unnecessarily bloated Garry's Mod addon sizes.
• gimp-vtf: A GIMP plugin to load and save VTF files.
• gm_addon_optimization_tricks: A desktop tool to optimize Garry's Mod addons/maps.
• 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.
• MareTF: An open source MIT-licensed CLI/GUI tool that can create, extract from, preview the contents of and write to every variant of VTF file. Replicates the functionality of Valve's vtex.exe and VTFEdit.
• Myst IV: Revolution: Performs various fixes for the game Myst IV: Revelation.
• PBR-2-Source: A Python-powered GUI for converting PBR materials into materials compatible with the Source engine.
• QVTF++: A QImageIO plugin to load VTF textures, based on panzi's QVTF plugin.
• RectMaker: A freeware GUI tool that can create and modify .rect files used in Hammer++'s hotspotting algorithm.
• reloaded2ps3: Convert the PC version of Portal Reloaded to a playable PS3 game.
• Verifier: A small program that can build an index of a game's files, and validate existing files based on that index. Similar to Steam's "Verify integrity of game files" option, but without overwriting any files.
• VPKEdit: An open source MIT-licensed CLI/GUI tool that can create, extract from, preview the contents of and write to several pack file formats. Replicates the functionality of Valve's vpk.exe and GCFScape.
  • bsp-linux-fix: Patches maps which have improperly cased packed assets by repacking the assets, fixing an issue on Linux.
  • CS2-EomVotesFix: Fixes displaying workshop map names and thumbnails during end-of-match voting for LAN events.
  • dham: Modifies Dota 2 hero aliases based on a configuration file and packages the changes.
  • Linux BSP Case Folding Workaround: A bash script designed to resolve issues with improperly cased packed map assets in Source engine games on Linux. Extracting the assets allows the game to find them properly.
  • props_scaling_recompiler: Allows converting prop_scalable into a static prop, effectively implementing static prop scaling outside CS:GO.
  • rock:sail: CS2 client-side tool to use skins for free (only visible to the user of the tool).
  • vpk2wad_nd: Converts textures in a VPK to a WAD that can be used by Narbacular Drop maps.
• VTF Forge: A modern multiplatform recreation of VTFEdit, using Qt.
• WifeRadiant: The open-source, cross-platform level editor for idTech, Source Engine, and GoldSrc based games.

Games

	Local addon assets are packed with sourcepp. Verifier and VPKEdit are shipped with the game.
	Some bundled textures are created and/or compressed with MareTF. Some bundled assets are packed with VPKEdit.
	Game assets are packed with VPKEdit.
