GTAdhocToolchain

A toolchain for the Gran Turismo scripting language, Adhoc, from C#.

Adhoc is a scripting language that is used for roughly 99% of the entire games's logic, the native code serving mostly solely as the engine.

The toolchain contains the following:

• Adhoc Script Preprocessor / Parser / Compiler / CodeGen (.ad -> .adc)
  • Supports adhoc bytecode version 7 (GT4), 10 (GT4O/TT), 12 (GTPSP/GT5/GT6/GT Sport) with experimental support for Version 5 (GT4)
• Adhoc Project Builder
  • Compiles menu sources from a .yaml project file to .adc, .mproject, .mpackage
• VS Code Extension
• Menu Layout Reader/Serializer (mproject/mwidget)
• Script and Menu Layout Packager (GT6 .mpackage)
• Asset Packager (.gpb)
• Script Disassembler (.adc to assembly-like syntax)
• Compare scripts for dissasembly matching

Current State

The toolchain is capable of compiling fully working original and custom projects (see OpenAdhoc).

Adhoc Language Specifications

Adhoc is very similar to javascript but with a few changes and additions. Refer to the language spec.

TODOs

• Improve syntatic analysis during compilation.
• Further document the language and instructions themselves.
• Examples
• Possibly tests
• API Documentation

Compiler

A fork of esprima-dotnet is used to lex and parse the Adhoc code into an abstract syntax tree prior to compiling.
