Editor Support

Lumen provides first-class support for VS Code through a dedicated extension that includes syntax highlighting, diagnostics, and deep AI-native features.

VS Code Extension

The official Lumen extension is available on the Open VSX Registry.

Installation

1. Open VS Code.
2. Go to the Extensions view (Ctrl+Shift+X).
3. Search for Lumen.
4. Click Install.

Alternatively, install it via the command line:

code --install-extension lumen-lang.lumen-lang

Features

• Syntax Highlighting: Beautiful theme-aware highlighting for .lm.md files.
• Language Server: Powered by lumen-lsp (bundled with the extension).
• Diagnostics: Real-time error reporting and type-checking.
• AI Tool Integration: Hover over tool calls to see documentation and live status.

Other Editors

Lumen uses the Language Server Protocol (LSP). You can use any LSP-compatible editor (Vim/Neovim, Emacs, Sublime Text) by installing the lumen-lsp binary.

Installing the Language Server

If you used the One-liner Installation, you already have lumen-lsp in your path.

Otherwise, install it via Cargo:

cargo install lumen-lsp

Configure your editor to use lumen-lsp for .lm.md files.
