# Enma

Enma is a Python library designed to fetch manga and doujinshi data from various sources. It provides a unified interface to interact with different manga repositories, making it easier to retrieve manga details, search for manga, paginate through results, and fetch random manga.

## Requirements

- Python 3.9+

## Installation
```py
pip install enma
```

Ensure you have the required Python version:
```py
import sys

package_name = "enma"
python_major = "3"
python_minor = "9"

try:
    assert sys.version_info >= (int(python_major), int(python_minor))
except AssertionError:
    raise RuntimeError(f"{package_name!r} requires Python {python_major}.{python_minor}+ (You have Python {sys.version})")
```

## Features Comparison

Feature   | NHentai | Manganato
----------|---------|-----------
search    |    ✅   |     ✅    
random    |    ✅   |     🚫    
get       |    ✅   |     ✅    
paginate  |    ✅   |     🚫    
set_config|    ✅   |     🚫

## Usage

### Example 1: Using Default Available Sources

```py
from typing import cast
from enma import Enma, DefaultAvailableSources, CloudFlareConfig, NHentai, Sort

enma = Enma[DefaultAvailableSources]()

config = CloudFlareConfig(
    user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/117.0.0.0 Safari/537.36',
    cf_clearance=''
)

enma.source_manager.set_source(source_name='nhentai')
nh_source = cast(NHentai, enma.source_manager.source)
nh_source.set_config(config=config)

doujin = enma.random()
print(doujin)
```

### Example 2: Extending with Custom Sources
```py
from enum import Enum
from typing import cast
from enma import Enma, SourcesEnum, Manganato, IMangaRepository

class AvailableSources(SourcesEnum):
    NHENTAI = 'nhentai'
    MANGANATO = 'manganato'
    NEW_SOURCE = 'new-source'

enma = Enma[AvailableSources]()

enma.source_manager.add_source(source_name='new-source', source=Manganato()) # Source MUST be an instance of IMangaRepository
enma.source_manager.set_source(source_name=AvailableSources.MANGANATO)

manga = enma.random()
print(manga)
```

## Retrieving `user-agent` and `cf_clearance` for NHentai

To retrieve the `user-agent` and `cf_clearance` for NHentai:

1. **Open NHentai in your browser**: Navigate to the NHentai website.
2. **Open Developer Tools**:
    - **For Google Chrome**: Right-click on the webpage and select Inspect or simply press Ctrl + Shift + I (or Cmd + Option + I on Mac).
    - **For Firefox**: Right-click on the webpage and select Inspect Element or press Ctrl + Shift + I (or Cmd + Option + I on Mac).
3. **Navigate to the Network Tab**: In the Developer Tools panel, click on the Network tab. This tab captures all network requests made by the webpage.
4. **Reload the Page**: With the Network tab open, reload the NHentai website by pressing Ctrl + R (or Cmd + R on Mac). This ensures that all network requests are captured.
5. **Select the nhentai.net Request**: After reloading, you'll see a list of files on the left side of the Network tab. Click on the first file named nhentai.net. This represents the main request to the NHentai website.
6. **Find the Request Headers**: On the right side, you'll see several tabs like Headers, Preview, Response, etc. Make sure you're on the Headers tab. Scroll down until you find a section named Request Headers.
7. **Copy the user-agent and cf_clearance**:
    - **user-agent**: This is a string that tells the server which web browser is being used. Look for an entry named User-Agent and copy its value.
    - **cf_clearance**: This is a specific cookie set by CloudFlare for security purposes. Look for an entry named cf_clearance and copy its value.

![example](./images/user-agent.png)
## Example:

```py
config = CloudFlareConfig(
    user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/117.0.0.0 Safari/537.36',
    cf_clearance=''
)
```
> **Note**: The user-agent and cf_clearance values can change over time. If you encounter issues accessing NHentai through the Enma library, you might need to repeat the above steps to get updated values.

## Errors

While using the library, you might encounter some specific errors. Here's a description of each:

1. **InstanceError**: 
   - **Description**: Raised when an instance of an object is not of the expected type.
   - **Common Cause**: Trying to add a source that isn't an instance of `IMangaRepository`.

2. **SourceNotAvailable**: 
   - **Description**: Raised when attempting to access a source that isn't available in the defined source list.
   - **Common Cause**: Trying to set a source that hasn't been previously added.

3. **SourceWasNotDefined**: 
   - **Description**: Raised when trying to perform an action (like fetching a manga) without first defining a source.
   - **Common Cause**: Forgetting to set the source before performing an operation.

4. **ExceedRetryCount**: 
   - **Description**: Specific to the `NHentai` adapter. Raised when the `random` method fails to fetch a random doujin after several attempts.
   - **Common Cause**: Consecutive failures when trying to fetch a random doujin from NHentai.

5. **NhentaiSourceWithoutConfig**: 
   - **Description**: Raised when trying to make a request to NHentai without providing the necessary configurations.
   - **Common Cause**: Forgetting to provide the `user-agent` and `cf_clearance` when configuring the NHentai adapter.

When encountering one of these errors, refer to the description and common cause to assist in troubleshooting.

## Future Plans

We are actively working on introducing an asynchronous version of the Enma library to better cater to applications that require non-blocking operations. This version will be maintained in a separate repository to keep the core library lightweight. However, for ease of access and installation, you'll be able to install the asynchronous version directly using:

```bash
pip install enma[async]
```
Stay tuned for updates and ensure to check our repository for the latest advancements!
## Frequently Asked Questions (FAQ)

**Q: Can I add more sources to Enma?**</br>
A: Yes! Enma is designed to be extensible. You can add more sources by extending the `SourcesEnum` and implementing `IMangaRepository` that contains the required methods for the new source.

**Q: I'm facing issues with a specific source. What should I do?**</br>
A: Ensure you have the latest version of Enma. If the issue persists, please raise an issue on our GitHub repository detailing the problem.

**Q: How often is Enma updated?**</br>
A: Enma is updated regularly as new sources are added or when there are significant changes to existing sources.
