# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Build Commands
### Build variants
- `make` - Make and install debug version. Usually all that's needed.
- `make fast` - Build optimized version
- `make release` - Build release version with LTO and optimizations
- `make small` - Build minimal size version
- `make web` - Build for web/emscripten platform
- `make crosswin` - Cross-compile for Windows using mingw32
Run 'make' to make cell.
### Testing
After install with 'make', just run 'cell' and point it at the actor you want to launch. "cell tests/toml" runs the actor "tests/toml.js"

## Scripting language
This is called "cell", a variant of JavaScript with important differences. See docs/cell.md for detailed language documentation.
### Common development commands
- `meson setup build_<variant>` - Configure build directory
- `meson compile -C build_<variant>` - Compile in build directory
- `./build_dbg/prosperon examples/<example>` - Run example from build directory
- Copy prosperon to game directory and run: `cp build_dbg/prosperon <game-dir>/ && cd <game-dir> && ./prosperon`
## Architecture Overview
Prosperon is an actor-based game engine inspired by Douglas Crockford's Misty system. Key architectural principles:
Prosperon is an actor-based game engine.
### Actor Model
- Each actor runs on its own thread
