Mascarpone 🧀

Interactive CLI tool for scaffolding Tiramisu game projects

Named after the Italian cream cheese used in tiramisu, Mascarpone provides a delightful TUI experience for creating new game projects with the Tiramisu game engine.

Installation

gleam add --dev mascarpone

Usage

Run the interactive project creator:

gleam run -m mascarpone

The TUI will guide you through:

1. Lustre Integration: Choose whether to include Lustre for UI overlays (menus, HUDs, etc.)
2. Project Template (Optional): Select from:
   • 2D Game - Orthographic camera and sprite setup
   • 3D Game - Perspective camera with lighting
   • Physics Demo - Physics-enabled objects
   • Skip - Don’t create template files (for existing projects)
3. Desktop Bundle: Set up NW.js for desktop distribution

What It Creates

Mascarpone sets up your Tiramisu project with:

• Lustre dev tools installed to priv/<project-name>/ with bundled Bun runtime
• gleam.toml with all necessary dependencies (tiramisu, vec, lustre_dev_tools, optionally lustre)
• .gitignore for Gleam projects
• package.json and node_modules/ with Three.js and Rapier3D installed via Bun
• Main source file with a working game example (if template selected)
• Lustre dev tools configuration with Three.js and Rapier3D import maps

Features

• 🎨 Beautiful TUI powered by Shore
• 🚀 Quick project setup with sensible defaults
• 🎮 Multiple game templates to start from (optional)
• 📦 Automatic dependency management via gleam add
• 🖥️ Desktop bundling with NW.js for cross-platform distribution
• ⚙️ Configurable options for Lustre UI and Rapier3D physics
• ♻️ Can be run on existing projects to add NW.js support

After Creation

For Web Development

Run the dev server:

gleam run -m lustre/dev start

Then open http://localhost:1234 in your browser to see your game!

For Desktop Development (if NW.js bundling was selected)

Building Desktop Distributions

If you set up NW.js bundling during project creation, you can build platform-specific distributions with a single command:

gleam run -m mascarpone bundle

This command:

• Uses the Bun runtime from lustre-dev-tools
• Runs bun run build which executes the build script in your package.json
• Compiles your Gleam code with gleam build
• Creates platform distributions with nwbuild

The built distributions will be available in the directory specified in your package.json (typically ../<project-name>_build/).

Using Mascarpone with Existing Projects

⚠️ Important: If you’re adding NW.js support to an existing project, make sure to skip the template selection when prompted. Selecting a template will overwrite your existing game code in src/!
