Suggestion: add option to print youtube author id along with author name about chat-downloader HOT 2 CLOSED

Hi there.

Yes, custom formatting is on the list to-do. In fact, I am busy with it right now in the package branch.

When you say

there should be option to display message author id along with author name for easier access.

What are you referring to by "easier access"? If you are only using the text which is output the console, you would need to do string manipulation later on in order to extract the author id.

I recommend to use the raw JSON data if you need access to more information. The current implementation has a simple to use python module too (with callback functionality), so you can customize the output to your liking, without needing to do any string manipulation.

Just so I can close the issue, here is an example of how you would use the python module to achieve what you were looking for:

from chat_downloader import ChatDownloader
from chat_downloader.utils import multi_get

url = 'https://www.youtube.com/watch?v=5qap5aO4i9A'
chat = ChatDownloader().get_chat(url)                   # create a generator
for message in chat:                                    # iterate over messages
    author_id = multi_get(message, 'author', 'id')      # get author id (None if doesn't exist)
    standard_message = chat.format(message)             # format message as normal
    print(author_id, standard_message)                  # print the author id along with the message

Another (more advanced) way would be to define a custom formatting json file (e.g. see the json file in
custom_formats.zip ) and use the format arguments

Format Arguments:
  --format FORMAT       Specify how messages should be formatted for printing, defaults to the site's default value
  --format_file FORMAT_FILE
                        Specify the path of the format file to choose formats from, defaults to None

For example, using this example.json (in example.zip )

{
    "example": {
        "template": "{time_text|timestamp}{author.badges}{money.text}{author.display_name|author.name}{author.id}{message}",
        "keys": {
            "time_text": "{} | ",
            "timestamp": {
                "template": "{} | ",
                "format": "%Y-%m-%d %H:%M:%S"
            },
            "author.badges": {
                "template": "({}) ",
                "separator": ", "
            },
            "money.text": "*{}* ",
            "author.id" : " ({})",
            "message": ": {}"
        }
    }
}

and running the following command:

chat_downloader https://www.youtube.com/watch?v=5qap5aO4i9A --format example --format_file example.json

would output as:
