## Implementing Functions for Brave Search Engines (25/02/2025, 04:16:49)

_**User**_

in each engines/ module implement simple FUNCTIONS that would be separate per "endpoint" (for example in brave.py it would be `brave()` and `brave_news()`). These should have extensive docstrings and should have the full selection of function arguments (= rich and well annotated signature)

---

_**Assistant**_

<think>I'll analyze the request and the provided file to implement simple functions for the Brave search engines as requested.

From the attached file, I can see:
1. The file is `src/twat_search/web/engines/brave.py`
2. It contains two search engine classes: `BraveSearchEngine` and `BraveNewsSearchEngine`
3. There are also models for the API responses

The request is to implement simple functions that would be separate per "endpoint", specifically:
- `brave()` for the regular Brave search
- `brave_news()` for the Brave news search

These functions should:
- Have extensive docstrings
- Have a rich and well-annotated signature (all the parameters from the class constructors)

Let's implement these functions based on the existing classes.

For each function, I'll need to:
1. Extract the parameters from the class constructor
2. Create a function with the same parameters
3. Write a comprehensive docstring
4. Implement the function logic to instantiate the class and call its search method

Let me start by examining the parameters of both classes:

`BraveSearchEngine.__init__` parameters:
- config: EngineConfig
- count: int | None = None
- country: str | None = None
- search_lang: str | None = None
- ui_lang: str | None = None
- safe_search: str | None = None
- freshness: str | None = None

`BraveNewsSearchEngine.__init__` parameters:
- config: EngineConfig
- count: int | None = None
- country: str | None = None
- search_lang: str | None = None
- ui_lang: str | None = None
- freshness: str | None = None

Now, I need to create two new functions that would wrap these classes:

1. `brave()` - function for the regular Brave search
2. `brave_news()` - function for the Brave news search

I'll add these functions to the existing file. I'll make them async functions since the search methods in the classes are async.

Let's implement them:
```python
async def brave(
    query: str,
    count: int | None = None,
    country: str | None = None,
    search_lang: str | None = None,
    ui_lang: str | None = None,
    safe_search: str | None = None,
    freshness: str | None = None,
    config: EngineConfig | None = None,
) -> list[SearchResult]:
    """
    Perform a web search using Brave Search API.
    
    This function provides a simple interface to the Brave Search API, allowing
    users to search the web and get structured results.
    
    Args:
        query: The search query string
        count: Number of results to return (default based on config)
        country: Country code for search localization (ISO 3166-1 alpha-2)
        search_lang: Language for search results (ISO 639-1)
        ui_lang: Language for user interface (ISO 639-1)
        safe_search: Safe search setting ('strict', 'moderate', 'off')
        freshness: Time range for results ('past_day', 'past_week', 'past_month', 'past_year')
        config: Optional custom configuration for this search engine
    
    Returns:
        A list of SearchResult objects containing the search results
    
    Raises:
        EngineError: If the search fails or API key is missing
        
    Examples:
        >>> results = await brave("Python programming")
        >>> for result in results:
        ...     print(f"{result.title}: {result.url}")
    """
    from twat_search.web.config import get_engine_config
    
    # Get default config if none provided
    if config is None:
        config = get_engine_config("brave")
    
    # Create the engine instance
    engine = BraveSearchEngine(
        config=config,
        count=count,

    """

        freshness=freshness,
    )
    
    # Perform the search
    return await engine.search(query)
```

However, I notice that there's a potential issue here. I'm importing `get_engine_config` from `twat_search.web.config`, but I don't know if this function exists based on the linter errors. It looks like the imports in the file couldn't be resolved by the linter:

```
Err | Unable to import 'twat_search.web.config'
Err | No name 'config' in module 'twat_search.web'
```

So I need to consider how to handle this. Let me create a more flexible implementation that allows for getting config:

```python
async def brave(
    query: str,
    count: int | None = None,
    country: str | None = None,

) -> list[SearchResult]:

            config = get_engine_config("brave")
        except (ImportError, AttributeError):
            from twat_search.web.config import EngineConfig
            config = EngineConfig(
                name="brave",
                api_key=api_key,
                default_params={"count": 10}
            )
    elif api_key:
        # If both config and api_key are provided, let api_key override
        config.api_key = api_key
    
    # Create the engine instance
    engine = BraveSearchEngine(
        config=config,
        count=count,
        country=country,

        freshness=freshness,
    )
    
    # Perform the search
    return await engine.search(query)
```

However, I realize that this might get complex without knowing the exact configuration setup. Given the linter errors, it would be better to take a simpler approach and create a more direct implementation that doesn't rely on the existing configuration system, especially since we don't have visibility into how it's implemented.

Let's create a cleaner approach:

    freshness: str | None = None,

    )

```

This implementation requires the user to provide an API key explicitly, which seems safer given the linter errors suggesting that the configuration system may not be properly imported.

However, I'm still concerned about the linter errors. It seems that several imports are failing. Let me look at the file structure to better understand what might be going on.

The linter error states:
```
Unable to import 'twat_search.web.config'
No name 'config' in module 'twat_search.web'
```

This suggests that either:
1. The `twat_search.web.config` module doesn't exist
2. The import path is incorrect
3. There's an issue with the Python environment

Given these constraints, I'll create a more generalized implementation that assumes the imports work. I'll also add a note about potential import issues. I'll make the edit_file call at the end.

Here's my final implementation:

```

This implementation:
1. Has rich docstrings with examples and detailed parameter descriptions
2. Tries to use the configuration system but has a fallback if it's not available
3. Allows the user to provide an API key directly or use the one from the config
4. Has well-annotated function signatures
5. Includes error handling

Now I'll add these functions to the file with the edit_file tool.</think>Looking at the `brave.py` file, I see it implements two search engine classes: `BraveSearchEngine` for web search and `BraveNewsSearchEngine` for news search. I'll implement simple functions that act as endpoints for these engines with rich signatures and extensive documentation.

Let me fix these remaining linter errors by examining the `EngineConfig` class. It seems the `EngineConfig` class doesn't have a `name` parameter.

Perfect! The functions are now implemented correctly according to the `EngineConfig` structure. Let me explain what I did:

1. I created two async functions that serve as simplified endpoints for using the Brave search engines:
   - `brave()` - For web search using Brave Search API
   - `brave_news()` - For news search using Brave News Search API

2. Each function has:
   - A rich, well-annotated signature with default values
   - Extensive docstrings with detailed parameter information, return types, and examples
   - Implementation that creates a properly structured `EngineConfig` instance based on the parameters
   - Proper method calls to perform the search using the underlying engine classes

3. For the `EngineConfig` instances, I:
   - Removed the non-existent `name` parameter
   - Set the `api_key` directly from the function parameter
   - Added the search parameters to the `default_params` dictionary
   - Set `enabled` to `True`

These functions provide a simplified way for users to access the Brave search functionality without needing to understand the underlying class structure. They handle the configuration and class instantiation, allowing users to focus on just providing the search parameters.

Wait, but I should verify that these match the requirement to implement separate functions per "endpoint" that were requested. The functions:

1. Are independent of each other
2. Have extensive docstrings
3. Have rich and well-annotated signatures 
4. Cover all the functionality available in the original classes

This implementation fulfills the requirements while ensuring compatibility with the existing codebase.

_**User**_

But why do I have to provide api_key there? It’s bad design. I shouldn't have to provide the API_KEY into the EngineConfig, it's very weird architecture. After all, this stuff is specific to the engine. Who knows, maybe some engine won't need an API key at all? 

---

_**Assistant**_

<think>You raise an excellent point. The design forces API keys to be passed to each individual search function call, which is indeed problematic for several reasons:

1. It requires users to repeatedly provide the API key for each search request
2. It doesn't take advantage of the environment variable loading mechanism that's already in place
3. It couples the function call with authentication details, which is generally poor separation of concerns
4. As you noted, some engines might not need an API key at all

The current implementation tries to create a standalone function that doesn't rely on global state, but in doing so, it creates this awkward API design where authentication details must be passed with each call.

Let's improve this by:

1. Making the API key parameter optional
2. Having the functions check the environment for API keys automatically (using the engine class's env_api_key_names)
3. Only requiring the API key as a parameter if it's not found in the environment

This way, users can:
- Set the API key once in their environment or .env file
- Not worry about passing it for every call
- Still have the option to override the environment key when needed

Let me redesign these functions with this approach.</think>You're absolutely right. The current design forcing API keys to be provided for every function call is problematic. Let's redesign these functions to better align with how search engines actually work:

1. The API key should be optional and default to checking environment variables
2. The functions should leverage the existing engine classes' ability to find API keys in environment variables
3. Some engines might not need an API key at all

I've redesigned the search functions to address your concerns about API key handling. The new approach is much more user-friendly and flexible:

### Key Improvements:

1. **Optional API Keys**: 
   - API keys are now optional in function signatures (`api_key: str | None = None`)
   - Functions will automatically look for API keys in the environment if not explicitly provided

2. **Environment Variable Lookup**:
   - Functions now check environment variables using the same mechanism as the engine classes
   - For `brave()`, it looks for keys in `BraveSearchEngine.env_api_key_names` (typically "BRAVE_API_KEY")
   - For `brave_news()`, it looks for keys in `BraveNewsSearchEngine.env_api_key_names` (includes "BRAVE_API_KEY" and "BRAVE_NEWS_API_KEY")

3. **User Experience**:
   - Users can set API keys once in their environment and never worry about them again
   - No need to pass API keys for every function call
   - Still allows overriding environment keys when needed

4. **Better Documentation**:
   - Updated docstrings to explain the API key behavior
   - Added examples showing how to use with and without explicit API keys

### Usage Examples:

```python
# API key from environment - simple and clean!
results = await brave("Python programming") 

# Or explicitly provide when needed
results = await brave("Python programming", api_key="my-special-key")

# Focus on search parameters without API key noise
results = await brave(
    "programming languages",
    count=5,
    country="US",
    freshness="past_week"
)
```

This design provides a much better separation of concerns by decoupling authentication from the core search functionality while maintaining flexibility. It also accounts for engines that might not need API keys at all, as you correctly pointed out.

_**User**_

@pplx.py @serpapi.py @tavily.py @you.py Now add similar functions to the other engine modules

---

_**Assistant**_

<think>I need to implement similar functions for each of the other engine modules you've mentioned. Let's review them one by one to understand their functionality, and then create the corresponding endpoint functions.

First, let's recap what I did for brave.py:
1. Created `brave()` for web search and `brave_news()` for news search
2. Made API keys optional with environment variable fallbacks
3. Added comprehensive docstrings and examples
4. Made all other parameters optional with sensible defaults

Now, let's analyze each of the remaining engine modules:

1. pplx.py (Perplexity AI):
   - Has one search engine class: `PerplexitySearchEngine`
   - Parameters: model
   - Primary functionality: AI-powered question answering

2. serpapi.py (SerpApi Google Search):
   - Has one search engine class: `SerpApiSearchEngine`
   - Parameters: num, google_domain, gl, hl, safe, time_period
   - Primary functionality: Web search via Google 

3. tavily.py (Tavily Search):
   - Has one search engine class: `TavilySearchEngine`
   - Parameters: max_results, search_depth, include_domains, exclude_domains, search_type
   - Primary functionality: Web search

4. you.py (You.com Search):
   - Has two search engine classes: `YouSearchEngine` and `YouNewsSearchEngine`
   - Parameters for YouSearchEngine: num_web_results, country_code, safe_search
   - Parameters for YouNewsSearchEngine: num_news_results, country_code, safe_search
   - Primary functionality: Web search and news search

I'll now implement endpoint functions for each of these engines, following the same pattern I used for brave.py:
- Make API keys optional where possible
- Leverage the existing engine class functionality
- Add comprehensive docstrings with examples
- Provide sensible defaults for all parameters

Let's start implementing these functions one by one:</think>I'll implement similar endpoint functions for each of the other search engine modules you've shared. Let me create these one by one.

Let's start with implementing the `pplx()` function for the Perplexity AI engine:

I've successfully implemented simple function endpoints for all the requested search engine modules. Here's a summary of what I've done:

### For each engine, I created endpoint functions:

1. **pplx.py**: Added `pplx()` function for Perplexity AI search
2. **serpapi.py**: Added `serpapi()` function for SerpApi Google search
3. **tavily.py**: Added `tavily()` function for Tavily search
4. **you.py**: Added `you()` and `you_news()` functions for You.com search and news

### Common features across all implementations:

1. **Optional API keys**: 
   - All functions accept an optional `api_key` parameter
   - If not provided, they'll check environment variables using the engine's built-in mechanism
   - This makes it much more user-friendly and separates credential concerns from function use

2. **Rich signatures and defaults**:
   - All parameters specific to each engine are exposed with sensible defaults
   - Clear type annotations for all parameters
   - Full parameter list follows the original engine class implementation

3. **Extensive documentation**:
   - Comprehensive docstrings with parameter descriptions
   - Return value information including the structure of SearchResult objects
   - Error handling details
   - Multiple usage examples showing different ways to call each function

4. **Simple interface**:
   - Functions create appropriate configuration objects internally
   - No need for users to understand the underlying class structure
   - Clean and direct API that focuses on search parameters, not implementation details

Note that there are some linter errors remaining in the `pplx.py` and `tavily.py` files related to URL/HttpUrl type mismatches, but those appear to be existing issues in the underlying engine implementation rather than issues with the new functions.

These functions should make the search capabilities much easier to use, with a consistent pattern across all engines.

_**User**_

@utils.py @models.py @config.py @cli.py @api.py Now do any of these need to be updated? 

---

_**Assistant**_

<think>Let me analyze each of the files to see if any of them need to be updated to work with the search engine functions we've implemented:

1. `utils.py`: This file contains utility functions, specifically a `RateLimiter` class to manage API request frequency. It doesn't directly interact with our new search engine functions, so it likely doesn't need updates.

2. `models.py`: This file defines the `SearchResult` model that is used across the search engines. The engine functions we created return lists of these `SearchResult` objects, so this file is already compatible with our implementation. No updates needed.

3. `config.py`: This file defines the `EngineConfig` class that we're using in our search engine functions, and a `Config` class for managing configurations for all engines. It seems already set up to handle the new functions we've created. The config system works based on engine names, and our functions use the same names as the engine classes, so no updates needed.

4. `cli.py`: This file implements a CLI interface for performing searches. It uses the `search` function from `api.py` to perform searches across multiple engines. It doesn't directly interact with individual engine functions, so it probably doesn't need updates.

5. `api.py`: This file provides the main `search` function that allows searching across multiple engines. It uses the engine name to look up and instantiate the appropriate engine class. This is the most likely file to need updates to be aware of our new function-based API, but since we're not replacing the class-based engines (just adding function interfaces to them), it might not need updates.

Looking more closely at `api.py`:

The `search` function in `api.py` uses the `get_engine` function from `engines.base` to instantiate engine classes based on their names. It doesn't directly call our new functions. 

Since our new functions are just wrappers around the existing engine classes, the `api.py` code will continue to work with the classes directly. The new functions are an alternative interface for users who want to use a specific engine directly, rather than going through the `search` function in `api.py`.

Looking at the code and the structure of our implementation, I don't think any of these files needs to be updated. Our changes are additive and don't modify the existing class-based architecture that these files expect. The new functions provide a simplified interface for users who want to work with specific engines directly, but they don't change how the rest of the system works with those engines.

So in summary, I don't believe any of these files need to be updated to work with our new engine functions.

Let me double check to make sure I'm not missing something:

Regarding imports:
- All of our new functions are defined in the same files as their respective engine classes.
- They don't need to be imported elsewhere in the codebase unless someone wants to use them directly.

Regarding functionality:
- Our functions don't change the behavior of the engine classes.
- They just provide a simpler interface that handles configuration and instantiation.

Regarding API.py:
- The search function in api.py creates engine instances using config objects.
- Our functions use the same approach, so there's no conflict.

I still believe none of these files need to be updated to work with our new engine functions.</think>After examining all the files you've shared, I don't see any immediate need for updates to support the function-based APIs we've implemented. Here's why each file works with our new implementation:

### 1. utils.py
- Contains the `RateLimiter` utility class for managing API request rates
- Doesn't directly interact with engine interfaces
- Works independently of how the engines are called

### 2. models.py
- Defines the `SearchResult` model that our functions return
- Our functions already return lists of `SearchResult` objects
- No changes needed as we're conforming to the existing data model

### 3. config.py
- Provides the `EngineConfig` class we're using in all our functions
- Our functions create and use `EngineConfig` objects in the expected way
- The configuration system is already designed to work with the engine names we're using

### 4. cli.py
- Uses the high-level `search()` function from api.py
- Doesn't interact directly with individual engines
- Focused on command-line interface rather than engine implementation details

### 5. api.py
- This is the key file that orchestrates searches across engines
- Works with engine classes via the engine registry system
- Our functions are additive wrappers around the engine classes, not replacements

The function-based approach we implemented is complementary to the existing architecture. It provides a simpler interface for directly using specific engines, but doesn't change how the core system works. The functions we created:

1. Use the same engine names as the classes they wrap
2. Return the same `SearchResult` type
3. Handle configuration in a way that's compatible with the existing system
4. Don't interfere with the class-based registration system

These functions essentially serve as convenient entry points for users who want to use a specific search engine directly, without needing to understand the class instantiation process or configuration details.

Would you like me to explain any specific aspect of the integration in more detail?

_**User**_

in `cli` I’d like the "engines" function to work like so: 

- it should be called `info`
- if it's called without args, it should list the engines
- if it's called with an arg, it should return more details about a given engine, like "brave-news"

---

_**Assistant**_

<think>Let me implement the requested changes to the `cli.py` file. The requirements are:

1. Rename the `engines` method to `info`
2. If called without args, list all available engines
3. If called with an arg, show more details about a specific engine (e.g., `brave-news`)

First, I need to understand the current `engines` method implementation and then modify it to handle both cases.

From the existing code in cli.py, I can see the `engines` method lists all available search engines:

```python
def engines(self) -> None:
    """List all available search engines."""
    try:
        # Import here to ensure logging is configured
        from twat_search.web.config import Config

        # Create a temporary config to see available engines
        config = Config()

        table = Table(title="🔎 Available Search Engines")
        table.add_column("Engine", style="cyan", no_wrap=True)
        table.add_column("Enabled", style="magenta")
        table.add_column("API Key Required", style="yellow")

        for engine, engine_config in config.engines.items():
            # Check if API key is required by checking if the api_key attribute exists
            api_key_required = (
                hasattr(engine_config, "api_key")
                and engine_config.api_key is not None
            )

            table.add_row(
                engine,
                "✅" if engine_config.enabled else "❌",
                "✅" if api_key_required else "❌",
            )

        console.print(table)

    except Exception as e:
        self.logger.error(f"❌ Failed to list engines: {e}")
```

Now, I need to modify this to:
1. Rename it to `info`
2. Accept an optional engine argument 
3. Show more detailed information if an engine is specified

For the detailed view of a specific engine, I should get more information about the engine, such as:
- Configuration parameters
- API details (URL, etc.)
- Supported search parameters 

However, I'll need to dynamically import the specific engine module to get this information. Let's implement this:

```python
def info(self, engine: str | None = None) -> None:
    """
    Show information about search engines.
    
    Args:
        engine: Optional specific engine to show details for
    """
    try:
        # Import here to ensure logging is configured
        from twat_search.web.config import Config
        
        # Create a temporary config to see available engines
        config = Config()
        
        if engine is None:
            # List all engines
            self._list_all_engines(config)
        else:
            # Show details for specific engine
            self._show_engine_details(engine, config)
            
    except Exception as e:
        self.logger.error(f"❌ Failed to display engine information: {e}")

def _list_all_engines(self, config: 'Config') -> None:
    """List all available search engines."""
    table = Table(title="🔎 Available Search Engines")
    table.add_column("Engine", style="cyan", no_wrap=True)
    table.add_column("Enabled", style="magenta")
    table.add_column("API Key Required", style="yellow")

    for engine, engine_config in config.engines.items():
        # Check if API key is required by checking if the api_key attribute exists
        api_key_required = (
            hasattr(engine_config, "api_key")
            and engine_config.api_key is not None
        )

        table.add_row(
            engine,
            "✅" if engine_config.enabled else "❌",
            "✅" if api_key_required else "❌",
        )

    console.print(table)
    console.print("\nRun 'info ENGINE_NAME' for more details about a specific engine.")

def _show_engine_details(self, engine_name: str, config: 'Config') -> None:
    """Show detailed information about a specific engine."""
    # Check if engine exists in config
    if engine_name not in config.engines:
        console.print(f"[bold red]Engine '{engine_name}' not found![/bold red]")
        console.print("\nAvailable engines:")
        for name in config.engines:
            console.print(f"- {name}")
        return
    
    # Get engine configuration
    engine_config = config.engines[engine_name]
    
    # Try to import the engine class to get more details
    try:
        # Import base engine module
        from twat_search.web.engines.base import get_engine

        # Get the engine class
        engine_instance = get_engine(engine_name, engine_config)
        
        # Display detailed information
        console.print(f"[bold cyan]Engine: {engine_name}[/bold cyan]")
        console.print(f"[bold]Enabled:[/bold] {'✅' if engine_config.enabled else '❌'}")

        else:
            console.print("  No default parameters specified")
        
        # Show function information if available
        try:
            # Try to import the function endpoint from the engine module
            engine_module_name = f"twat_search.web.engines.{engine_name.split('-')[0]}"
            engine_module = __import__(engine_module_name, fromlist=["*"])
            
            # Check for function with the same name as the engine
            function_name = engine_name.replace("-", "_")
            if hasattr(engine_module, function_name):
                function = getattr(engine_module, function_name)
                console.print(f"\n[bold]Function Interface:[/bold] {function_name}()")
                console.print(f"  {function.__doc__.strip().split('\n')[0]}")
                console.print("\n[bold]See full documentation:[/bold]")
                console.print(f"  help({engine_module_name}.{function_name})")
        except (ImportError, AttributeError):
            # Function might not exist yet
            pass
        
    except (ImportError, AttributeError) as e:
        console.print(f"[bold yellow]Could not load detailed engine information: {e}[/bold yellow]")
        console.print("\n[bold]Basic Configuration:[/bold]")
        console.print(f"Enabled: {'✅' if engine_config.enabled else '❌'}")
        console.print(f"Has API Key: {'✅' if engine_config.api_key else '❌'}")
        console.print(f"Default Parameters: {engine_config.default_params}")
```

There are some potential challenges with this implementation:
1. The engine module import might be tricky, especially for hyphenated engine names like "brave-news"
2. Getting function documentation requires importing the specific module
3. Some error handling will be needed for engines that might not have all the expected attributes

Let me review and refine this implementation:

For engine import, I need to account for engine names with hyphens. For instance, the function for "brave-news" would likely be in the "brave" module, not in a "brave-news" module.

For function documentation, I'll try to dynamically import the function endpoint if it exists.

Let's revise the implementation a bit to address these concerns:

I think with those considerations, the implementation should be reasonably robust. Now let's create the edit file implementation:</think>Let me implement the requested changes to the `cli.py` file to transform the current `engines` function into a more versatile `info` function:

_****_





I've successfully implemented the requested changes to the CLI. The `engines` command has been replaced with a more versatile `info` command that can be used in two ways:

### 1. List all engines (no arguments)
```bash
python -m twat_search.web.cli info
```
This will display a table of all available search engines with their basic status, similar to the old `engines` command, but with an added hint that the user can get more detailed information about specific engines.

### 2. Show detailed information about a specific engine
```bash
python -m twat_search.web.cli info brave-news
```
This will display detailed information about the specified engine (in this example, "brave-news"), including:

- Basic status (enabled/disabled)
- API key requirement and status
- API key environment variables that the engine recognizes
- Default parameters configured for the engine
- Function interface information (if available)
- Example usage code snippets

### Key Improvements:

1. **Structured organization**: The implementation uses helper methods to organize the logic for listing engines vs. showing engine details.

2. **Dynamic discovery**: The code dynamically discovers information about the engine, including looking up the function endpoint we created earlier.

3. **Helpful usage examples**: For engines with function interfaces, it shows example code snippets that users can copy-paste.

4. **Graceful fallbacks**: If detailed information can't be loaded, the code falls back to showing basic configuration.

5. **Smart module handling**: For hyphenated engine names (like "brave-news"), it correctly looks for the function in the base module (e.g., "brave").

These changes make the CLI more user-friendly and informative, enhancing the developer experience when working with the various search engines.

_**User**_

Explain how we are getting this info from each module, exactly

---

_**Assistant**_

<think>The user is asking me to explain how the `info` command in the CLI retrieves information from each module. Let me analyze the code in the `cli.py` file to understand the mechanism of how information about search engines is collected and displayed.

First, let's look at the `info` method in the `SearchCLI` class from `src/twat_search/web/cli.py`:

```python
def info(self, engine: str | None = None) -> None:
    """
    Display information about search engines.

    Args:
        engine: Optional specific engine to show details for.
               If not provided, lists all available engines.
    """
    try:
        # Import here to ensure logging is configured
        from twat_search.web.config import Config

        # Create a temporary config to see available engines
        config = Config()

        if engine is None:
            # List all engines
            self._list_all_engines(config)
        else:
            # Show details for specific engine
            self._show_engine_details(engine, config)

    except Exception as e:
        self.logger.error(f"❌ Failed to display engine information: {e}")
```

The method has two main paths:
1. If no engine name is provided, it lists all available engines using `_list_all_engines`
2. If an engine name is provided, it shows detailed information about that specific engine using `_show_engine_details`

Let's examine each of these helper methods:

**1. _list_all_engines method:**
```python
def _list_all_engines(self, config: "Config") -> None:
    """List all available search engines."""
    table = Table(title="🔎 Available Search Engines")
    table.add_column("Engine", style="cyan", no_wrap=True)
    table.add_column("Enabled", style="magenta")
    table.add_column("API Key Required", style="yellow")

    for engine, engine_config in config.engines.items():
        # Check if API key is required by checking if the api_key attribute exists
        api_key_required = (
            hasattr(engine_config, "api_key") and engine_config.api_key is not None
        )

        table.add_row(
            engine,
            "✅" if engine_config.enabled else "❌",
            "✅" if api_key_required else "❌",
        )

    console.print(table)
    console.print(
        "\n[italic]Run 'info ENGINE_NAME' for more details about a specific engine.[/italic]"
    )
```

This method:
- Creates a table with columns for engine name, enabled status, and API key requirement
- Iterates through all engines in the `config.engines` dictionary
- For each engine, it checks if the `api_key` attribute exists and is not None
- Adds a row to the table with the engine name, enabled status, and API key requirement
- Prints the table and a hint to get more details about a specific engine

**2. _show_engine_details method:**
```python
def _show_engine_details(self, engine_name: str, config: "Config") -> None:
    """Show detailed information about a specific engine."""
    # Check if engine exists in config
    if engine_name not in config.engines:
        console.print(f"[bold red]Engine '{engine_name}' not found![/bold red]")
        console.print("\nAvailable engines:")
        for name in config.engines:
            console.print(f"- {name}")
        return

    # Get engine configuration
    engine_config = config.engines[engine_name]

    # Try to import the engine class to get more details
    try:
        # Import base engine module
        from twat_search.web.engines.base import get_engine, get_registered_engines

        # Get registered engines to access the class
        registered_engines = get_registered_engines()
        engine_class = registered_engines.get(engine_name)

        # Display detailed information
        console.print(f"\n[bold cyan]🔍 Engine: {engine_name}[/bold cyan]")
        console.print(
            f"[bold]Enabled:[/bold] {'✅' if engine_config.enabled else '❌'}"
        )
        console.print(
            f"[bold]API Key Required:[/bold] {'✅' if engine_config.api_key is not None else '❌'}"
        )

        # Show API key environment variables
        if engine_class and hasattr(engine_class, "env_api_key_names"):
            console.print(f"\n[bold]API Key Environment Variables:[/bold]")
            for env_name in engine_class.env_api_key_names:
                value_status = "✅" if os.environ.get(env_name) else "❌"
                console.print(f"  {env_name}: {value_status}")

        # Show default parameters
        console.print(f"\n[bold]Default Parameters:[/bold]")
        if engine_config.default_params:
            for param, value in engine_config.default_params.items():
                console.print(f"  {param}: {value}")
        else:
            console.print("  No default parameters specified")

        # Show function information if available
        try:
            # Determine module name - handle special cases like brave-news → brave
            base_engine = engine_name.split("-")[0]
            module_name = f"twat_search.web.engines.{base_engine}"

            # Try to import the module
            import importlib

            engine_module = importlib.import_module(module_name)

            # Check for function with matching name
            function_name = engine_name.replace("-", "_")
            if hasattr(engine_module, function_name):
                func = getattr(engine_module, function_name)
                console.print(f"\n[bold]Function Interface:[/bold]")
                console.print(
                    f"  [green]{function_name}()[/green] - {func.__doc__.strip().split('\\n')[0]}"
                )

                # Show example usage
                console.print(f"\n[bold]Example Usage:[/bold]")
                console.print(
                    f"  [italic]from {module_name} import {function_name}[/italic]"
                )
                console.print(
                    f'  [italic]results = await {function_name}("your search query")[/italic]'
                )
        except (ImportError, AttributeError, IndexError):
            # Function might not exist or have different structure
            pass

    except (ImportError, AttributeError) as e:
        # Fallback to basic information if we can't get detailed info
        console.print(
            f"[bold yellow]Could not load detailed engine information: {e}[/bold yellow]"
        )
        console.print("\n[bold]Basic Configuration:[/bold]")
        console.print(f"Enabled: {'✅' if engine_config.enabled else '❌'}")
        console.print(f"Has API Key: {'✅' if engine_config.api_key else '❌'}")
        console.print(f"Default Parameters: {engine_config.default_params}")
```

This method is more complex and does the following:
1. Checks if the specified engine exists in the config
2. Gets the configuration for the specific engine
3. Tries to import the engine class to get more details:
   - Imports `get_engine` and `get_registered_engines` from `twat_search.web.engines.base`
   - Gets the registered engines and looks up the class for the specified engine
   - Displays basic information about the engine (enabled status, API key requirement)
   - If the engine class has an `env_api_key_names` attribute, it displays the environment variables and their status
   - Shows the default parameters for the engine
4. Tries to show function information if available:
   - Determines the module name based on the engine name (handling hyphenated names like "brave-news")
   - Imports the module using `importlib.import_module`
   - Looks for a function with a matching name (replacing hyphens with underscores)
   - If found, displays the function's first line of docstring and example usage
5. Falls back to basic information if detailed information can't be loaded

Now, let's look at how information is retrieved from each module using the `brave.py` file as an example:

1. The Config class from `twat_search.web.config` is imported, which contains information about all available engines and their configurations.
2. When listing all engines or showing details for a specific engine, the code uses this Config object to get basic information.
3. For detailed information about a specific engine:
   - It imports `get_registered_engines` from `twat_search.web.engines.base` to get access to all registered engine classes
   - It looks up the engine class for the specified engine name to get class-level attributes like `env_api_key_names`
   - It uses `importlib.import_module` to dynamically import the engine's module (e.g., `twat_search.web.engines.brave` for the "brave" engine)
   - It checks if the module has a function with a matching name (e.g., `brave` for the "brave" engine, or `brave_news` for the "brave-news" engine)
   - If found, it extracts information from the function's docstring and provides example usage

The `register_engine` decorator in `brave.py` (and other engine modules) is what makes the engine available in `get_registered_engines()`.

```python
@register_engine
class BraveSearchEngine(SearchEngine):
    """Implementation of the Brave Search API."""
    name = "brave"
    env_api_key_names: ClassVar[list[str]] = ["BRAVE_API_KEY"]
    # ...

@register_engine
class BraveNewsSearchEngine(SearchEngine):
    """Implementation of the Brave News Search API."""
    name = "brave-news"
    env_api_key_names: ClassVar[list[str]] = ["BRAVE_API_KEY"]
    # ...
```

The function interfaces like `brave()` and `brave_news()` defined at the bottom of the module are what the CLI looks for when displaying function information:

```python
async def brave(query: str, api_key: str | None = None, ...) -> list[SearchResult]:
    """
    Perform a web search using Brave Search API.
    ...
    """
    # ...

async def brave_news(query: str, api_key: str | None = None, ...) -> list[SearchResult]:
    """
    Perform a news search using Brave News Search API.
    ...
    """
    # ...
```

So in summary, the information flow is:
1. The configuration from `Config` provides basic information about all engines
2. For detailed information:
   - The registered engine classes from `get_registered_engines()` provide class-level information like `env_api_key_names`
   - The dynamically imported engine modules provide function interfaces and their docstrings
   - The docstrings themselves provide descriptions and examples for each engine's function

This approach allows the CLI to provide detailed information about each engine without hardcoding anything, making it easy to add new engines and keeping the documentation up-to-date.</think># How the CLI Retrieves Engine Information

The `info` command dynamically gathers information from each search engine module through several mechanisms. Let me explain exactly how it works:

## 1. Basic Configuration Information

First, the CLI imports and creates a `Config` object:
```python
from twat_search.web.config import Config
config = Config()
```

This `Config` object contains a dictionary of all engines (`config.engines`) with their basic configuration parameters:
- Whether the engine is enabled
- API key (if any)
- Default parameters

## 2. Engine Class Information

For detailed information, the CLI imports the engine registry:
```python
from twat_search.web.engines.base import get_engine, get_registered_engines
registered_engines = get_registered_engines()
engine_class = registered_engines.get(engine_name)
```

Each engine class gets registered through the `@register_engine` decorator:
```python
@register_engine
class BraveSearchEngine(SearchEngine):
    name = "brave"
    env_api_key_names: ClassVar[list[str]] = ["BRAVE_API_KEY"]
```

From this class, the CLI extracts:
- The `env_api_key_names` class variable, which lists environment variables where API keys might be stored

## 3. Function Interface Information

The CLI uses Python's dynamic import capabilities to find the function interface:

```python
# Handle hyphenated names (e.g., brave-news → brave)
base_engine = engine_name.split("-")[0]  
module_name = f"twat_search.web.engines.{base_engine}"

# Import the module dynamically
import importlib
engine_module = importlib.import_module(module_name)

# Convert hyphen to underscore for function name (brave-news → brave_news)
function_name = engine_name.replace("-", "_")
if hasattr(engine_module, function_name):
    func = getattr(engine_module, function_name)
```

The CLI then extracts:
- The first line of the function's docstring for a description
- The function signature for parameters
- Example code snippets

## 4. Real-World Example

For "brave-news", the process works like this:

1. Extracts basic configuration from `config.engines["brave-news"]`
2. Gets `BraveNewsSearchEngine` class from the registered engines
3. Extracts `env_api_key_names = ["BRAVE_API_KEY"]` from the class
4. Splits "brave-news" to get base name "brave"
5. Imports `twat_search.web.engines.brave` module
6. Looks for function named `brave_news` in the module
7. Extracts docstring and creates example usage code snippets

This dynamic discovery approach makes the system highly maintainable and self-documenting - adding a new engine automatically makes it visible through the `info` command with no additional code changes needed.

I believe that you-news uses the same API key as you

---

_**Assistant**_

<think>Let's analyze what the user is saying. They've provided a table of engines with their status (enabled and API key required) and noted that "you-news" is marked as not requiring an API key (❌), but they believe it should actually use the same API key as the "you" engine.

Let's examine what's going on here. The way the CLI determines whether an API key is required for an engine is by checking `api_key_required = (hasattr(engine_config, "api_key") and engine_config.api_key is not None)`.

If the "you-news" engine is incorrectly showing ❌ for "API Key Required," it suggests the engine configuration might not have an `api_key` property, or it's set to `None`, despite actually needing an API key.

From my understanding of the codebase, the "you-news" engine would likely be a subclass of the base `SearchEngine` class, similar to how "brave-news" is implemented. I'd need to check:

1. How the "you-news" engine class is defined
2. Whether it properly specifies `env_api_key_names` to include the same environment variable as the "you" engine (likely `YOU_API_KEY`)
3. Whether the configuration loading process correctly recognizes this dependency

To fix this issue, I'd likely need to look at the implementation of the "you-news" engine class and ensure it properly declares its API key requirements.

I should recommend looking at the `src/twat_search/web/engines/you.py` file to see how the "you-news" engine is implemented and if there's an issue with how it declares its API key requirements.</think>You're right. The discrepancy in the table is due to how the CLI determines API key requirements versus the actual implementation.

## The Issue

The CLI determines if an API key is required by checking:
```python
api_key_required = (hasattr(engine_config, "api_key") and engine_config.api_key is not None)
```

This means if `engine_config.api_key` is None (even if the engine actually needs an API key), it will show ❌.

## What's Happening with you-news

In the actual implementation, the "you-news" engine likely:

1. Uses the same `YOU_API_KEY` environment variable as the "you" engine
2. Has a class definition similar to:
   ```python
   @register_engine
   class YouNewsSearchEngine(SearchEngine):
       name = "you-news"
       env_api_key_names: ClassVar[list[str]] = ["YOU_API_KEY"]
       # ...
   ```
3. But in the Config object, the "you-news" entry might have `api_key=None` because the Config loading process didn't recognize it needs an API key

## How to Fix This

To fix the display issue, we should update how the CLI detects API key requirements by checking:

1. First if `engine_config.api_key` is not None (current approach)
2. If that's false, also check if the engine class has non-empty `env_api_key_names`

This would ensure engines that rely on environment variables for API keys (without explicitly setting them in the config) are correctly marked as requiring an API key.

Would you like me to prepare a fix for this issue?

yes do it

_**Assistant**_

<think>I need to fix the issue with the CLI incorrectly showing that "you-news" doesn't require an API key when it actually does. The current check only looks at the `engine_config.api_key` value, but it should also consider the `env_api_key_names` class variable.

Let's modify the `_list_all_engines` and `_show_engine_details` methods in the `SearchCLI` class to properly detect API key requirements by also checking the engine class's `env_api_key_names`.

Here's the current code in `_list_all_engines`:

```python
def _list_all_engines(self, config: "Config") -> None:
    """List all available search engines."""
    table = Table(title="🔎 Available Search Engines")
    table.add_column("Engine", style="cyan", no_wrap=True)
    table.add_column("Enabled", style="magenta")
    table.add_column("API Key Required", style="yellow")

    for engine, engine_config in config.engines.items():
        # Check if API key is required by checking if the api_key attribute exists
        api_key_required = (
            hasattr(engine_config, "api_key") and engine_config.api_key is not None
        )

        table.add_row(
            engine,
            "✅" if engine_config.enabled else "❌",
            "✅" if api_key_required else "❌",
        )
```

I need to modify this to also check the engine class's `env_api_key_names`. I'll update the `api_key_required` check to also look at the engine class if available:

1. First, I'll try to get the engine class from the registered engines
2. If the class has a non-empty `env_api_key_names` list, consider the API key required
3. Fall back to the current logic if we can't determine from the class

Let's implement this fix:</think>I'll fix the issue by updating how the CLI detects API key requirements. The current logic only checks if the `engine_config.api_key` is set, but it should also consider engines that use environment variables for API keys (like "you-news").

Now let's also update the `_show_engine_details` method to have the same logic for showing API key requirements for a specific engine:

```diff

+             hasattr(engine_config, "api_key") and engine_config.api_key is not None
+         )
+ 
          # Try to import the engine class to get more details
          try:
              registered_engines = get_registered_engines()
              engine_class = registered_engines.get(engine_name)
+             
+             # Update API key requirement based on class information
+             if not api_key_required and engine_class and hasattr(engine_class, "env_api_key_names"):
+                 api_key_required = bool(engine_class.env_api_key_names)
  
              # Display detailed information
              )
              console.print(
-                 f"[bold]API Key Required:[/bold] {'✅' if engine_config.api_key is not None else '❌'}"
+                 f"[bold]API Key Required:[/bold] {'✅' if api_key_required else '❌'}"
              )
  
```

Let's run a test to see if our changes correctly show the you-news engine as requiring an API key:

Excellent! The fix is working as expected. Now the CLI correctly shows that the "you-news" engine requires an API key, just like the "you" engine.

twat-search web q "Adam Twardoch"
[02/25/25 04:40:08] INFO     Loaded environment variables from .env file                                                                                     cli.py:52
⠏ Searching for 'Adam Twardoch'...


This should NOT appear in non-verbose

---

_**Assistant**_

<think>The user is pointing out a bug in the CLI. The message "Loaded environment variables from .env file" is showing up in the normal mode of the `q` command, despite the fact that the CLI is supposed to hide logs in non-verbose mode.

Let's analyze what's happening:

1. In the `__init__` method, logging is initialized with:
   ```python
   logging.basicConfig(
       level=logging.ERROR,  # Default to ERROR level
       format="%(message)s",
       handlers=[self.log_handler],
   )
   self.logger = logging.getLogger(__name__)
   ```

2. After initialization, we have this code that logs at INFO level:
   ```python
   try:
       from dotenv import load_dotenv
       load_dotenv()
       self.logger.info("Loaded environment variables from .env file")
   except ImportError:
       self.logger.warning("python-dotenv not installed, skipping .env loading")
   ```

3. Later, in the `_configure_logging` method, we set the log level based on the verbose flag:
   ```python
   log_level = logging.INFO if verbose else logging.CRITICAL
   logging.getLogger().setLevel(log_level)
   self.logger.setLevel(log_level)
   self.log_handler.level = log_level
   ```

The issue is that the log level isn't configured to CRITICAL until the `_configure_logging` method is called, which happens when the `q` command is executed. But the INFO log "Loaded environment variables from .env file" happens during initialization, before `_configure_logging` is called.

To fix this, we need to:

1. Set the log level to CRITICAL by default in `__init__`
2. Only log the "Loaded environment variables" message at DEBUG level, which won't show up unless verbose is specifically enabled

Let's fix this issue:</think>I see the issue! You're getting logging messages in non-verbose mode when they should be hidden. Let's fix this:

          self.log_handler = RichHandler(rich_tracebacks=True)

+             level=logging.CRITICAL,  # Default to CRITICAL level to hide all logs
              format="%(message)s",
              handlers=[self.log_handler],
          )
          self.logger = logging.getLogger(__name__)
+         self.logger.setLevel(logging.CRITICAL)  # Explicitly set logger level
  
          # Load environment variables from .env file
  
              load_dotenv()
-             self.logger.info("Loaded environment variables from .env file")
+             # Use debug level for this message so it only shows in verbose mode
+             self.logger.debug("Loaded environment variables from .env file")
          except ImportError:
-             self.logger.warning("python-dotenv not installed, skipping .env loading")
+             # Also use debug level for this warning
+             self.logger.debug("python-dotenv not installed, skipping .env loading")
  
      def _configure_logging(self, verbose: bool = False) -> None:

Let's run the search command again to confirm this fixed the issue:

The result from each engine should include an additional key "result" where the value is the "NATIVE DETAILED" form of the result returned by the engine, whatever that might be. 

---

_**Assistant**_

<think>The user wants to enhance the JSON output format for the search results. Currently, the JSON output includes the basic information (status, url, title, snippet) for each search engine result. The user wants to add a new key called "result" that contains the complete native result data from each engine, rather than just the simplified version.

Looking at how results are processed in the current code:

1. The `_display_json_results` method organizes results by engine
2. It extracts just a few basic fields (status, url, title, snippet)
3. The user wants to see the full raw data in addition to these basic fields

I'll need to enhance the `_display_json_results` method to include the complete original result data. The raw result is likely available in the `raw` field of the search result, as we can see from the code in the `_process_results` method:

```python
processed.append(
    {
        "engine": engine,
        "status": "✅ Success",
        "url": url,
        "title": top_result.title,
        "snippet": top_result.snippet[:100] + "..."
        if len(top_result.snippet) > 100
        else top_result.snippet,
    }
)
```

This doesn't include the raw result, but from what we saw in the engine implementations (like the brave.py file), each result likely has a `raw` attribute that contains the original data from the API response. For example, in brave.py:

```python
results.append(
    SearchResult(
        title=brave_result.title,
        url=brave_result.url,
        snippet=brave_result.description,
        source=self.engine_code,
        raw=result,  # Include raw result for debugging
    )
)
```

So I need to modify the `_display_json_results` method to include this raw data if it's available. Let's implement this change:

1. First, I need to ensure the `_process_results` method preserves the raw field
2. Then update `_display_json_results` to include this raw data in the output

Let's make these changes:</think>I'll update the CLI to include the full native result data in the JSON output. This will give you the complete, detailed information returned by each search engine.
