DAL Support (VS Code / Cursor)

VS Code extension for DAL (dist_agent_lang): language registration for .dal files and LSP client that starts the DAL language server (dal lsp).

Features

• Language: Registers dal for .dal files with syntax highlighting (TextMate grammar: keywords, types, strings, comments, attributes, operators). Grammar is synced from .vscode/extensions/dist-agent-lang/syntaxes/; that folder is the canonical source for syntax rules.
• LSP: Starts the language server via dal lsp (diagnostics, hover, completion, go to definition, signature help). Requires the DAL CLI built with --features lsp.
• Tasks: "Run DAL file" and "Check DAL file" (Run Task / Ctrl+Shift+B).

Requirements

• DAL CLI on your PATH, built with LSP support:

  cargo build --release --features lsp
  # or: cargo install --path . --features lsp
  

• Node.js 18+ (for npm install when developing the extension).

Installation

From source (development)

1. Clone the repo and build DAL with LSP: cargo build --release --features lsp.
2. Install extension dependencies: cd vscode-dal && npm install.
