## Modules

### Chat

The `chat` module provides a `ChatService` class that simplifies interaction with different language model (LLM) connectors.

- `chat_service.py`: Contains the `ChatService` class for interacting with LLMs.

### Connectors

The `connectors` module includes connectors for various databases and LLMs.

- `base.py`: Defines the abstract base class for connectors.
- `db/`: Contains database connectors.
  - `postgres_connector.py`: Connector for PostgreSQL.
  - `mongo_connector.py`: Connector for MongoDB.
- `llm/`: Contains LLM connectors.
  - `openai_connector.py`: Connector for OpenAI API.
  - `azure_connector.py`: Connector for Azure AI API.

### Utils

The `utils` module contains utility functions that are commonly used across different modules.

- `formatting.py`: Functions for formatting prompts.
- `logging.py`: Functions for setting up logging.
- `response_handling.py`: Functions for handling LLM responses.

### Config

The `config.py` file contains configuration logic to select the appropriate connectors based on the environment or other criteria.

### Installing the Repository

First, install the `prowritingaid-sdk` dependency for grammar checker.

```sh
pip install git+https://github.com/prowriting/prowritingaid.python.git
```
Then, install our package
```sh
pip install mle_core
```

## Usage

### Setting Up Environment Variables

Ensure you have the following environment variables set for database and LLM connectors:

For PostgreSQL:

```
DATABASE_USER=your_db_user
DATABASE_PASSWORD=your_db_password
DATABASE_HOST=your_db_host
DATABASE_PORT=your_db_port
DATABASE_NAME=your_db_name
```

For MongoDB:

```
MONGO_URI=your_mongo_uri
MONGO_DB_NAME=your_mongo_db_name
```

For OpenAI:

```
OPENAI_API_KEY=your_openai_api_key
```

For ChatAnthropic:
```
ANTHROPIC_API_KEY=your_anthropic_api_key
```

For Azure AI:

```
AZURE_ENDPOINT=your_azure_endpoint
AZURE_API_KEY=your_azure_api_key
AZURE_DEPLOYMENT_NAME=your_azure_deployment_name
```

### Using the Chat Service

```python
from mle_core.chat import ChatService

import asyncio
from dotenv import load_dotenv
from mle_core.chat.chat_service import ChatService

load_dotenv()


async def main():
    llm_type='openai' # or "azure" or "anthropic"
    chat_service = ChatService(llm_type)

    method = 'sync'  # or async
    response_method = 'invoke'  # or "batch" or "stream"
    system_message = 'You are a helpful assistant.'
    user_message = 'What is the weather like today?'
    model_name = "gpt-3.5-turbo"
    input = {
        "system_message": system_message,
        "user_message": user_message
    }
    if method == "sync":
        response = chat_service.get_sync_response(
        response_method, 
        input, 
        model_name=model_name, 
        temperature=0.2, 
        max_tokens=1000, 
        is_structured=False, 
        pydantic_model=None)
        print(response)

    elif method == "async":
        response = await chat_service.get_async_response(
        response_method, 
        input, 
        model_name=model_name, 
        temperature=0.2, 
        max_tokens=1000,
        is_structured=False, 
        pydantic_model=None)
        print(response)


asyncio.run(main())
```

### Using the Chat Service for structured output

```python
from mle_core.chat import ChatService
import asyncio
from dotenv import load_dotenv
from mle_core.chat.chat_service import ChatService
from langchain_core.pydantic_v1 import BaseModel, Field

load_dotenv()

#create a pydnatic model
class Joke(BaseModel):
    setup: str = Field(description="setup of the joke")
    punchline: str = Field(description="punchline of the joke")

async def main():
    llm_type='openai' # or "azure" or "anthropic"
    chat_service = ChatService(llm_type)
    
    method = 'sync'  # or async
    response_method = 'invoke'  # or "batch" or "stream"
    system_message = 'You are a helpful assistant.'
    user_message = 'What is the weather like today?'
    model_name = "gpt-3.5-turbo"
    input = {
        "system_message": system_message,
        "user_message": user_message
    }
    if method == "sync":
        response = chat_service.get_sync_response(
            response_method, 
            input, 
            model_name=model_name,
            temperature=0.2, 
            max_tokens=1000, 
            is_structured=True, 
            pydantic_model=Joke)
        print(response)

    elif method == "async":
        response = await chat_service.get_async_response(
            response_method, 
            input, 
            model_name=model_name, 
            temperature=0.2, 
            max_tokens=1000,
            is_structured=True, 
            pydantic_model=Joke)
        print(response)


asyncio.run(main())
```


### Note: Using Chat Service

1. If response_method is "batch" the input should be list of input. 

Example: 
```
system_message = 'You are a helpful assistant.'
input = [{'system_message': system_message, 'user_message': 'Tell me a bear joke.'}, {'system_message': system_message, 'user_message': 'Tell me a cat joke.'}]
```


### Using Database Connectors

```python
from mle_core.config import get_db_connector

def main():
    db_type = "postgres"  # or "mongo"
    db_connector = get_db_connector(db_type)
    db_connection = db_connector.get_connection()
    print(db_connection)

if __name__ == "__main__":
    main()
```

### Using Evaluators

```python
from mle_core.evaluators.tests_results_generation import Evaluator

def main():
    input_file_path = 'test_case.json'
    output_file_path = 'output_file.csv'
    output_file_type = 'csv'

    # assume your evaluator_function be f_eval_function 
    try:
        evaluator = Evaluator(input_file_path,f_eval_function, output_file_path, output_file_type.lower())
        evaluator.execute()
        print("Processing completed successfully.")
    except Exception as e:
        print(f"An error occurred: {str(e)}")

if __name__ == '__main__':
    main()

```
### Using Checkers

#### Fact checker and hyperbole detector
```python
from mle_core.checkers import f_hyperbole_detector, f_fact_checker

# The context basically refers to the knowledge base
# question is generally the user prompt to the system
# answer generally is the LLM generated output

fact = f_fact_checker(question, context, answer)
hyperbole = f_hyperbole_detector(question, context, answer)
```

#### Database consistency checker
```python
from mle_core.connectors.db import Neo4jConnector
from mle_core.checkers import Neo4jSanityCheck

uri = os.getenv('NEO4J_URI')
user = os.getenv('NEO4J_USERNAME')
password = os.getenv('NEO4J_PASSWORD')
if not uri or not user or not password:
    raise ValueError("Missing one or more required environment variables: NEO4J_URI, NEO4J_USERNAME, NEO4J_PASSWORD")

neo4j_connection = Neo4jConnector(uri=uri, user=user, password=password)


def check_database_consistency():
    try:
        neo4j_sanity_check = Neo4jSanityCheck(neo4j_connection)
        results = neo4j_sanity_check.run_checks()
        return results
    except Exception as e:
        print(f"An error occurred during database consistency check: {str(e)}")

```


#### Grammar checker

```python
# language-tool-python

from mle_core.checkers import JsonGrammarChecker

def check_grammar_language_tool(json):
    result = {"success": True, "error": []}
    keywords = ['a','b']          # these are the words not to run the grammar checker on
    json_grammar_checker = JsonGrammarChecker(json, keywords)
    errors = json_grammar_checker.check_json_for_errors()
    return errors

# Prowriter
def grammar_check_prowriter(prompt):
    try:
        result = check_grammar_prowriter(prompt)
        return result
    except Exception as e:
        print(f"An error occurred: {e}")
        return False


```
