Modules for working with Valve's Source Engine file formats, as well as a variety of tools using these.

Simply pip install srctools, you'll need Python 3.8+.

• math: Core vector, angles and matrix classes, with Cython accelerated versions.
• cmdseq: Reads and writes Hammer's expert compile command list format.
• filesys: Allows accessing VPKs, zips, folders etc using a unified interface, as well as a prioritised chain like the engine's game folder system.
• logger: Wrappers around the logging module allowing str.format interpolation support, among others.
• const: Various shared constants and enums.
• tokenizer: Cython-accelerated tokenizer for parsing the various text files.
• binformat: Some tools for handling binary file formats.

• keyvalues: Reads and writes KeyValues1 property trees.
• dmx: Reads and writes DMX / KeyValues2 format files.
• vmf: Reads and writes VMF map files.
• bsp: Reads and writes compiled BSP maps files.
• fgd: Reads and writes FGD entity definitions. A compressed database of definitions from most games is also included, from HammerAddons. Note that this parses a superset of the FGD format, including "tags" to allow specifying which entities and keyvalues are supported for different engine branches.
• mdl: Reads some parts of compiled MDL/VTX/VVD/PHY models.
• smd: Reads and writes SMD geometry data.
• sndscript: Reads and writes soundscripts.
• vmt: Reads and writes VMT material files.
• vpk: Reads and writes VPK packages.
• vtf: Reads and writes VTF images, including DXT compression.
• particles: Reads and writes PCF particle systems.

• game: Parses gameinfo.txt files, and handles accessing the searchpaths.
• instancing: Implements logic for collapsing func_instance into maps.
• packlist: Stores a list of files of various types, then computes dependencies recursively. This also includes a database of resources required by game code for different entity classes.
• run: Code to run a compiler, logging the output as it executes while still storing it.
