WorldKit VEML

VEML language support for building virtual worlds — syntax highlighting, validation, autocomplete, and scene navigation.

Features

Syntax Highlighting

Rich TextMate grammar for .veml files with element, attribute, and value highlighting.

Real-Time Validation

Diagnostic codes (VEML001–VEML399) catch errors as you type — parse errors, schema violations, and broken references.

Schema-Driven Autocomplete

Context-aware completions for elements, attributes, and values based on the VEML schema.

Go to Definition & Find All References

Navigate between entity references with Ctrl+Click and find all usages across your project.

Hover Documentation

Hover over any element or attribute to see schema documentation inline.

Scene Outline

Tree view showing your world's entity hierarchy with click-to-navigate.

Snippets

Quick-insert common VEML patterns: worlds, entities, environments, and more.

Project Scaffolding

Run WorldKit: New World Project from the Command Palette to scaffold a complete VEML project.

Document Formatting

Format your VEML files with proper indentation and structure.

Public Extension API

Third-party extensions can query entities, resolve references, and subscribe to world changes via the VemlWorldApi interface (v0.1.0 — experimental).

Getting Started

1. Install the extension from the VS Code Marketplace (search "WorldKit VEML").
2. Open a folder containing .veml files, or create a new project:
   • Open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
   • Run WorldKit: New World Project
   • Choose a location and project name
3. Start editing — autocomplete, validation, and hover docs activate automatically.
4. Explore your scene — open the Scene Outline in the Explorer sidebar to see your world's structure.

Tip: Create a .vemlproject file in your project root for automatic project detection.
