Sobakasu Language

Visual Studio Code language support for Sobakasu and Udon Assembly (UASM).

Sobakasu is a Udon-first programming language and compiler designed for developing VRChat worlds without depending on C# or UdonSharp.

Features

Language support for .sobakasu files:

use debug;

state count = 0;

on interact {
  count += 1;
  debug.log(count);
}

Syntax highlighting for .uasm files is also included.

.data_start

.data_end

.code_start

    PUSH, 0x00000000
    EXTERN, "UnityEngineDebug.__Log__SystemObject__SystemVoid"

.code_end

Sobakasu is a programming language and toolchain designed specifically for the VRChat Udon VM.

Its main goals are:

Udon-first — designed around Udon rather than adapting an existing general-purpose language
C#-independent — not constrained by C# syntax or language semantics
Unity integration — intended to integrate directly with the VRChat world development workflow
Higher-level language features — providing a more expressive language while compiling to Udon Assembly

Sobakasu is currently under active development and is not yet recommended for production use.

Install Sobakasu Language from the Visual Studio Code Marketplace.

For local development, the extension can also be installed from a .vsix package:

code --install-extension sobakasu-<version>.vsix

Language	Extension
Sobakasu	`.sobakasu`
Udon Assembly	`.uasm`

This extension provides Visual Studio Code language support.

The Sobakasu compiler and Unity integration are distributed as part of the main Sobakasu project.

See the main repository for installation instructions and documentation:

Sobakasu and this extension are still under development.

Language syntax and editor support may change as the language evolves.
