#       TL/DW: Too Long Didn't Watch
#
#  Project originally created by https://github.com/the-crypt-keeper
#  Modifications made by https://github.com/rmusser01
#  All credit to the original authors, I've just glued shit together.
#
#
# Usage:
#
#   Download Audio only from URL -> Transcribe audio:
#       python summarize.py https://www.youtube.com/watch?v=4nd1CDZP21s`
#
#   Download Audio+Video from URL -> Transcribe audio from Video:**
#       python summarize.py -v https://www.youtube.com/watch?v=4nd1CDZP21s`
#
#   Download Audio only from URL -> Transcribe audio -> Summarize using (`anthropic`/`cohere`/`openai`/`llama` (llama.cpp)/`ooba` (oobabooga/text-gen-webui)/`kobold` (kobold.cpp)/`tabby` (Tabbyapi)) API:**
#       python summarize.py -v https://www.youtube.com/watch?v=4nd1CDZP21s -api <your choice of API>` - Make sure to put your API key into `config.txt` under the appropriate API variable
#
#   Download Audio+Video from a list of videos in a text file (can be file paths or URLs) and have them all summarized:**
#       python summarize.py ./local/file_on_your/system --api_name <API_name>`
#
#   Run it as a WebApp**
#       python summarize.py -gui` - This requires you to either stuff your API keys into the `config.txt` file, or pass them into the app every time you want to use it.
#           Can be helpful for setting up a shared instance, but not wanting people to perform inference on your server.

#       Random issues I've encountered and how I solved them:
#   1. Something about cuda nn library missing, even though cuda is installed...
#       https://github.com/tensorflow/tensorflow/issues/54784 - Basically, installing zlib made it go away. idk.
#
#   2. ERROR: Could not install packages due to an OSError: [WinError 2] The system cannot find the file specified: 'C:\\Python312\\Scripts\\dateparser-download.exe' -> 'C:\\Python312\\Scripts\\dateparser-download.exe.deleteme'
#       Resolved through adding --user to the pip install command

    Summarizes a given text by splitting it into chunks, each of which is summarized individually.
    The level of detail in the summary can be adjusted, and the process can optionally be made recursive.

    Parameters: - text (str): The text to be summarized. - detail (float, optional): A value between 0 and 1
    indicating the desired level of detail in the summary. 0 leads to a higher level summary, and 1 results in a more
    detailed summary. Defaults to 0. - model (str, optional): The model to use for generating summaries. Defaults to
    'gpt-3.5-turbo'. - additional_instructions (Optional[str], optional): Additional instructions to provide to the
    model for customizing summaries. - minimum_chunk_size (Optional[int], optional): The minimum size for text
    chunks. Defaults to 500. - chunk_delimiter (str, optional): The delimiter used to split the text into chunks.
    Defaults to ".". - summarize_recursively (bool, optional): If True, summaries are generated recursively,
    using previous summaries for context. - verbose (bool, optional): If True, prints detailed information about the
    chunking process.

    Returns:
    - str: The final compiled summary of the text.

    The function first determines the number of chunks by interpolating between a minimum and a maximum chunk count
    based on the `detail` parameter. It then splits the text into chunks and summarizes each chunk. If
    `summarize_recursively` is True, each summary is based on the previous summaries, adding more context to the
    summarization process. The function returns a compiled summary of all chunks.
