# CDK FFI Bindings
UniFFI bindings for the CDK (Cashu Development Kit), providing foreign function interface access to wallet functionality for multiple programming languages.
## Supported Languages
- **🐍 Python** - With REPL integration for development
- **🍎 Swift** - iOS and macOS development
- **🎯 Kotlin** - Android and JVM development
## Development Tasks
### Build & Check
```bash
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
```bash
# 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
```bash
# 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
```bash
# Start development
just ffi-dev-python
# In the Python REPL:
>>> dir(cdk_ffi) # Explore available functions
>>> help(cdk_ffi.generate_mnemonic) # Get help
```
