OM Language for VS Code

Powerful VS Code extension for OM Lang (.om files) providing syntax highlighting, full IntelliSense, real-time diagnostics, code formatting, snippets, AST visualization, and integrated compiler support.

Supports multiple locales: full LSP for Hinglish, Hindi, Sanskrit + syntax highlighting for 6 additional Indian languages. Go to Definition, Find References, and Rename now work across your whole workspace, not just the open file.

Made with ❤️ by Anand Shah for the developer community

OM Lang is a localized variant of the V programming language — confirmed by directly analyzing and running the official compiler binary, not just guessed. This extension delivers a complete IDE experience built on that ground truth.

✨ Features

• 🌈 Multi-locale Syntax Highlighting (Hinglish, Hindi Devanagari, Sanskrit, Bengali, Gujarati, Kannada, Malayalam, Marathi, Tamil, Telugu)
• 🧠 Advanced Language Server with completion, hover, go-to-definition, references, rename, signature help, semantic tokens, document symbols
• 🗂️ Workspace-wide navigation — Go to Definition, Find References, and Rename see across every .om file in your project, not just the one you have open
• ▶️ Real Debug Adapter + working F5 — press F5 on a .om file and it just runs, streaming output into the Debug Console with a working Stop button. Honestly labeled: no breakpoints/stepping, since the v0.1 compiler itself has no debug protocol to hook into
• 🧬 Struct embedding support — EmbeddedType। promotes an embedded type's fields onto the outer struct, confirmed by directly running the compiler
• 📝 Configurable Formatter (indent size, brace style, import sorting)
• 🛠️ Robust Diagnostics for syntax, semantic errors, unused vars, unreachable code — now cross-file-aware, so multi-file projects don't get false "undefined" errors
• 📦 Rich Snippets for common patterns including error handling (or {}, ?), ranges, and struct embedding
• 🚀 Commands: Run File, Compile, Show AST, Show Parse Tree, Format, Restart Server
• 🔍 V-derived syntax support: range expressions (.. / ...), optional types (?Type), string interpolation with ₹ (including dotted paths like ₹obj.field)

See examples/ and examples/vendor/ for real OM Lang sample files that fully exercise the extension.

🚀 Installation

From Marketplace:

1. Open Extensions sidebar in VS Code
2. Search for "OM Language"
