# Changelog



All notable changes to this project will be documented in this file.



The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),

and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).



## [Unreleased]



### Planned

- [ ] Generator support for module-level functions

- [ ] gRPC streaming support

- [ ] Configuration composition (extends, mixins)

- [ ] LSP server for config authoring

- [ ] Auto-generated test suites from schemas



## [0.2.0] - 2025-10-26



### Added - Live Python Integration

- **Complete Python adapter** (`SnakeBridgeAdapter`) for dynamic library integration

  - `describe_library` tool - introspects any Python module via inspect

  - `call_python` tool - executes functions, creates instances, calls methods

  - Generic adapter works with ANY Python library (json, numpy, requests, etc.)

  - 12 Python tests, all passing



### Added - User-Facing Tools

- **Public API**: `SnakeBridge.discover/2`, `generate/1`, `integrate/2`

- **Mix tasks**:

  - `mix snakebridge.discover` - discover Python libraries

  - `mix snakebridge.validate` - validate configs

  - `mix snakebridge.generate` - generate modules

  - `mix snakebridge.clean` - clean caches

- **Setup script**: `scripts/setup_python.sh` - auto-install Python deps



### Added - Live Examples

- `examples/api_demo.exs` - works instantly, no Python needed

- `examples/json_live.exs` - live Python json module

- `examples/numpy_math.exs` - live NumPy (626 functions discovered!)

- `example_helpers.exs` - auto-manages Python dependencies



### Added - Documentation

- `docs/20251026/COMPLETE_USAGE_EXAMPLE.md` - comprehensive guide

- `docs/20251026/AI_AGENT_ADAPTER_GENERATION.md` - future automation architecture

- `docs/20251026/BASE_FUNCTIONALITY_ROADMAP.md` - development roadmap

- `docs/20251026/SNAKEBRIDGE_VS_RAW_SNAKEPIT.md` - value proposition



### Fixed

- All 54 broken tests now passing (100% test coverage)

- Generator now calls Runtime instead of placeholders

- Schema.Differ recursive diffing

- TypeSystem.Mapper smart capitalization (dspy → DSPy)

- Cache filesystem persistence

- Compiler warnings eliminated



### Changed

- Runtime uses generic `call_python` tool (was library-specific `call_dspy`)

- SnakepitMock supports both old and new tool names

- Development mode uses mocks by default (fast iteration)



### Test Results

- 76 Elixir tests passing ✅

- 12 Python tests passing ✅

- 6 integration tests passing ✅

- **88 total tests, 100% pass rate**



## [0.1.0] - 2025-10-25



### Added

- Initial release

- Core configuration schema

- Type system mapper

- Basic code generation

- Discovery framework
