Draton for Visual Studio Code

Official VS Code extension for the Draton programming language. Provides syntax highlighting, real-time diagnostics via the Language Server Protocol, and the bundled Draton Prism Night dark theme.

Features

Syntax Highlighting

Full TextMate grammar covering the Draton canonical syntax:

Keywords: let, mut, fn, pub, class, interface, enum, match, spawn, return, import
Type annotations: @type blocks, Result[T, E], chan[T]
String interpolation: f"Hello, {name}!"
Low-level blocks: unsafe, @pointer, @comptime, inline asm
Comments, operators, and literals

Language Server (LSP)

When drat or draton-lsp is available on PATH or in your project's target/ directory, the extension activates a full LSP client providing:

Diagnostics — type errors and syntax issues shown inline
Hover — type information on hover
Go to Definition — navigate to symbol definitions
Document Symbols — outline view with functions, classes, and enums
Completion — basic identifier completion

Draton Prism Night Theme

A built-in dark color theme tuned for Draton syntax. Activate it via Preferences → Color Theme → Draton Prism Night.

Requirements

VS Code 1.75.0 or later

For LSP features, install the Draton compiler (drat) from the GitHub Releases page or build from source. The extension works without drat — syntax highlighting and the theme are always available.

Installation

From the Marketplace

Search for Draton in the Extensions view (Ctrl+Shift+X / Cmd+Shift+X) and click Install.

From a VSIX file

Download the latest .vsix from GitHub Releases.
Open the Command Palette (Ctrl+Shift+P), run Extensions: Install from VSIX..., and select the file.

Or via the terminal:

code --install-extension draton.draton-<version>.vsix

Extension Settings

Setting	Default	Description
`draton.server.path`	`""`	Path to the `drat` or `draton-lsp` binary. Leave empty to use automatic resolution.
`draton.server.args`	`[]`	Additional arguments passed to the language server on startup.

Language server resolution order

When draton.server.path is empty the extension searches for the language server in this order:

target/debug/drat
target/release/drat
target/debug/draton-lsp
target/release/draton-lsp
drat on PATH
draton-lsp on PATH

Quick Start

# Install Draton (Linux / macOS)
curl -fsSL https://github.com/draton-lang/draton/releases/latest/download/install.sh | sh

# Install Draton (Windows PowerShell)
irm https://github.com/draton-lang/draton/releases/latest/download/install.ps1 | iex

# Verify
drat --version

Then open any .dt file — syntax highlighting activates immediately. If drat is on your PATH, the language server starts automatically when you open a Draton file.

Known Limitations

LSP features require drat or draton-lsp to be installed separately.
Windows aarch64 is not supported in the current Draton Early Tooling Preview.
