feat: Add JSON schema support for structured output, drop jsony - #19
Merged
Conversation
* Implement `--schema` flag for enforcing JSON output structure. * Update README with examples for using JSON schema. * Modify provider interfaces to accept schema, enabling structured responses. * Add `schema` parameter to `chat` methods across providers. * Integrate schema parsing and validation within provider logic. * Update tests to verify schema enforcement.
* Remove `jsony` from `seance.nimble` and `nimble.lock`. * Replace `jsony` serialization/deserialization with Nim's built-in `json` and `std/options` for all providers. * Update `openai.nim` to use `$(%*request)` for serialization and `to(parseJson(responseBodyContent), ChatResponse)` for deserialization. * Update `openrouter.nim` to use `$(%*request)` for serialization and `to(parseJson(responseBodyContent), ChatResponse)` for deserialization. * Update `anthropic.nim` to use `$(%*request)` for serialization and a custom `fromAnthropic` proc for deserialization. * Update `gemini.nim` to use `$(%*request)` for serialization and a custom `fromGemini` proc for deserialization.
* Implemented `fromOpenAI` procedure to parse OpenAI API responses. * Added `fromOpenRouter` procedure for parsing OpenRouter API responses. * Modified `OpenAIRouter` and `OpenRouter` providers to use their respective parsing procedures. * Updated tests for `OpenAI` and `OpenRouter` providers to include the "role" field in mock responses. * Removed unnecessary fields from OpenRouter requests.
* Refactor ProviderConfig to use Option[string] for model. * Update default models for Anthropic and OpenRouter. * Adjust tests for OpenAI, Gemini, and OpenRouter providers to use Option[string]. * Simplify getFinalModel logic in common.nim. * Add json_schema to OpenRouter provider. * Update version to 0.4.0. * Include options module in config.nim and t_config_loading.nim.
