The bot only needs the "Read Message History" permission.
Note: The bot will only be able to collect messages from channels it has access to.
In order to generate the necessary token and be able to use the bot, an application needs to be created on the Discord developer dashboard.
# git clone --recurse-submodules https://github.com/Erovia/cocoacollector.git
# python3 -m venv cocoacollector_venv
# source cocoacollector_venv/bin/activate
# python install -r requirements.txt
# mkdir <output_dir>
// To collect messages from every channel the bot has access to
# DISCORD_TOKEN=<token> python cocoacollector/cocoacollector.py <server_id> <output_dir>
// To collect messages from selected channels only
# DISCORD_TOKEN=<token> python cocoacollector/cocoacollector.py <server_id> <output_dir> --channel <channel1_id> <channel2_id>
// To collect messages from a specified user
# DISCORD_TOKEN=<token> python cocoacollector/cocoacollector.py <server_id> <output_dir> --channel <channel1_id> <channel2_id> --user_id <user_id>The output will be one CSV file per channel under the <output_dir> directory. The CSV files can be imported easily into LibreOffice Calc or MS Office Excel.
