<br><br><br>
## Description
pytchat is a python library for fetching youtube live chat
without using Selenium or BeautifulSoup.

Other features:
+ Customizable [chat data processors](https://github.com/taizan-hokuto/pytchat/wiki/ChatProcessor) including youtube api compatible one.
+ Available on asyncio context. 
+ Quick fetching of initial chat data by generating continuation params
instead of web scraping.

For more detailed information, see [wiki](https://github.com/taizan-hokuto/pytchat/wiki). <br>

## Examples


### Fetch chat data (see [wiki](https://github.com/taizan-hokuto/pytchat/wiki/PytchatCore))
```python
import pytchat
chat = pytchat.create(video_id="uIx8l2xlYVY")
while chat.is_alive():
    for c in chat.get().sync_items():
        print(f"{c.datetime} [{c.author.name}]- {c.message}")
```


### Output JSON format string (feature of [DefaultProcessor](https://github.com/taizan-hokuto/pytchat/wiki/DefaultProcessor))
```python
import pytchat
import time

chat = pytchat.create(video_id="uIx8l2xlYVY")
while chat.is_alive():
    print(chat.get().json())
    time.sleep(5)
    '''
    # Each chat item can also be output in JSON format.
    for c in chat.get().items:
        print(c.json())
    '''     
```


### other
+ Fetch chat with a buffer ([LiveChat](https://github.com/taizan-hokuto/pytchat/wiki/LiveChat))

+ Use with asyncio ([LiveChatAsync](https://github.com/taizan-hokuto/pytchat/wiki/LiveChatAsync))

+ YT API compatible chat processor ([CompatibleProcessor](https://github.com/taizan-hokuto/pytchat/wiki/CompatibleProcessor))


## Structure of Default Processor
Each item can be got with `sync_items()` function.
