🎉 VS Code Extension for TOON Format

Hi TOON team! I've built a comprehensive VS Code extension to make working with TOON files easier and more productive.

✨ Key Features

🎨 Syntax Highlighting

• Full color-coded syntax support for .toon files
• Highlights array headers, field definitions, keys, values, and delimiters
• Support for all TOON data types (strings, numbers, booleans, null)

✅ Real-time Validation

• Automatic validation as you type with smart debouncing
• Error highlighting with detailed messages
• Strict mode validation for array lengths and structure consistency
• Non-intrusive - only shows errors when document looks complete

🔄 Bidirectional Conversion

• Convert TOON → JSON with a single command
• Convert JSON → TOON with format options (nested or flattened)
• Smart flattening for maximum token savings
• Preserves data integrity during conversion

TOON to JSON Conversion:

JSON to TOON - Choose Format (Nested or Flattened):

📝 Developer Productivity

• Code snippets for common TOON patterns (arrays, objects, key-value pairs)
• Format on save support
• Configurable indentation and delimiters (comma, tab, pipe)
• Optional length markers ([#3] vs [3])

💰 Token Optimization

• Built-in flattening support to reduce LLM token usage
• Visual feedback on token savings
• Helps achieve 30-60% token reduction vs JSON

📦 Installation

Search for "TOON" in VS Code Extensions, or:

code --install-extension vishalraut.vscode-toon

🔗 Links

• Marketplace: https://marketplace.visualstudio.com/items?itemName=vishalraut.vscode-toon
• GitHub: https://github.com/vishalraut2106/vscode-toon
• Issues/Feedback: https://github.com/vishalraut2106/vscode-toon/issues

🎯 Why This Matters

This extension makes TOON a first-class citizen in VS Code, providing the same level of support developers expect from JSON, YAML, or any other data format. It lowers the barrier to adoption and makes it easier for developers to leverage TOON's token efficiency in their LLM workflows.

📝 Proposed Documentation Update

I'd love to have this added to the README under an "Editor Support" or "Tools & Integrations" section. Here's a suggested addition:

## Editor Support

### VS Code
- [TOON Language Support](https://marketplace.visualstudio.com/items?itemName=vishalraut.vscode-toon) - Full-featured extension with syntax highlighting, validation, JSON conversion, and token optimization tools

And its Live Now

Thanks for creating such a useful format! 🙌

There is already a Good response from users

[okineadev]

What would you say about moving this project to this organization so that this extension become official and can be maintained by the organization's members and you?

I certainly don't decide this, you should ask @johannschopplich if you want, this is just my idea of how it could be

[VishalRaut2106]

Thanks for the suggestion! I appreciate the idea of making TOON-extension an official project under the organization. That would definitely help with maintenance and community contributions. I'm open to it—let me discuss this with @johannschopplich. The main thing for me is ensuring TOON continues to grow and gets the support it needs. I'll follow up soon!

[VishalRaut2106]

Hi @johannschopplich , following the suggestion from @okineadev and others, I’m open to moving the VS Code extension under the toon-format org to make it an official project. I’d love to hear your thoughts on this and how we can collaborate to ensure the best support for TOON users going forward!

[johannschopplich]

@VishalRaut2106 Thanks for creating the VSCode extension! I'd love to host the extension under the TOON org umbrelly. I'm currently in the process of migrating ports – the TOON Java implementation today, for example.

Your extension is on the roadmap. I'll reach out, once we're there. 🙋‍♂️

[VishalRaut2106]

Thanks for supporting this extension! Let me know the next steps once you’re done with your pending work.
