Development Tasks

Build & Check

just ffi-build        # Build FFI library (release)
just ffi-build --debug # Build debug version
just ffi-check         # Check compilation
just ffi-clean         # Clean build artifacts

Generate Bindings

# Generate for specific languages
just ffi-generate python
just ffi-generate swift
just ffi-generate kotlin

# Generate all languages
just ffi-generate-all

# Use --debug for faster development builds
just ffi-generate python --debug

Development & Testing

# Python development with REPL
just ffi-dev-python    # Generates bindings and opens Python REPL with cdk_ffi loaded

# Test bindings
just ffi-test-python   # Test Python bindings import

Quick Start
