A template of the privacy policy is available here.

Features

• $\LaTeX$ render
• Math calculation
• Converting math input into $\LaTeX$ code

Install

You can build it and deploy it with Docker. Download the Dockerfile, the docker-compose.yml and the .env.example. Rename .env.example into .env and add your token inside. Now, you can start the bot.

It is also possible to compile it with Go 1.24+. You must have texlive (packages texlive texlive-binextra texlive-dvi xdvik texmf-dist-full for Alpine Linux) installed to run the bot. The token can be passed via the argument -token, e.g.

$ ./bot -token your_token

or via the environment variable TOKEN (in a .env file or directly in your environment variables)

Configuration

The config file is located at config/config.toml. The default file:

debug = false
author = 'nyttikord'
use_postgres_instead_of_sqlite = false

[sqlite]
path = 'nerdkord.db'

[postgres]
host = 'localhost'
user = 'nerdkord'
password = 'password'
db_name = 'nerdkord'
port = 5432
time_zone = 'Europe/Paris'

• debug is true if the bot is in debug mode (:warning: does not support user-side installs if this is true!)
• author is the host of the bot
• use_postgres_instead_of_sqlite is true if the bot must use PostreSQL instead of SQLite3
• [sqlite].path is a path to the SQLite3 file
• [postgres].host is the host of PostgreSQL

• [postgres].port is the port of PostreSQL
• [postgres].time_zone is the timezone to use with PostgreSQL
