Install

Donwload a binary from the GitHub releases page, or manually compile from source code.

Getting Started

When using nicodo for the first time, the session ID must be set. Once set, it is saved in the configuration file and you can skip this task from the next time.

At first, sign in to nicovideo.jp manually with your browser. Then, you have to find your user_session id from the cookie of nicovideo.jp in your browser:

user_session=XXXXXXX;

Specify the session id as below when using nicodo for the first time:

nicodo -u XXXXXXX <video id>

The configuration file is saved at ~/.local/share/nicodo/nicodo_config.json (Linux), ~/Library/Application Support/nicodo/nicodo_config.json (MacOS) or C:\Users\hoge\AppData\Local\nicodo\nicodo_config.json. (Windows)

If you cannot fetch comments because of invalid auth, remove the configuration file and renew the session ID.

Usage

Specify <video id> by extracting the XXXXXXX part of the video URL as shown below:

https://www.nicovideo.jp/watch/XXXXXXX

# save latest comments as XML format
nicodo <video id>
# save latest comments as JSON format
