RUDRA for VS Code 🔱

Syntax highlighting and live diagnostics (parse and type errors) for .rux files, powered by the rudra-lsp language server.

Prerequisites

1. Build the RUDRA toolchain so you have the rudra-lsp binary:

   cargo build --release
   # binary at target/release/rudra-lsp
   

2. Node.js + npm (to package the extension).
3. The vsce packaging tool:

   npm install -g @vscode/vsce
   

Install (local)

From this folder (editors/vscode):

npm install                     # fetch vscode-languageclient
vsce package                    # produces rudra-1.0.0.vsix
code --install-extension rudra-1.0.0.vsix

Then reload VS Code.

Point it at rudra-lsp

If rudra-lsp is not on your PATH, set the path in VS Code settings:

• Open Settings → search "rudra" → set Rudra: Lsp Path to the absolute path, e.g. /media/hdd/rudra-lang/target/release/rudra-lsp.

Or add to settings.json:

{
  "rudra.lspPath": "/absolute/path/to/rudra-lsp"
}

Use

Open any .rux file. You get:

• Syntax highlighting (keywords, types, strings, functions).
• Live diagnostics — parse and type errors appear underlined as you type, and in the Problems panel.

Quick test

Create test.rux:

fn main() {
    let x: int = "oops";   // type error — should be underlined
    print(x);
}

You should see an error on the assignment line.
