# The Artificer - A Dice Rolling Discord Bot
|
|
Version 1.4.3 - 2021/03/21
|
|
|
|
The Artificer is a Discord bot that specializes in rolling dice. The bot utilizes the compact [Roll20 formatting](https://artificer.eanm.dev/roll20) for ease of use and will correctly perform any needed math on the roll (limited to basic algebra).
|
|
|
|
This bot was developed to replace the Sidekick discord bot after it went offline many times for extended periods, and is now dead according to their GitHub. This was also developed to fix some annoyances that were found with Sidekick, specifically its vague error messages (such as `"Tarantallegra!"`, what is that supposed to mean) and its inability to handle implicit multiplication (such as `4(12 + 20)`).
|
|
|
|
## Using The Artificer
|
|
I am hosting this bot for public use and you may find its invite link below. If you would like to host this bot yourself, details of how to do so are found at the end of this README, but I do not recommend this unless you are experienced with running Discord bots.
|
|
|
|
After inviting the bot, if you would like it to remove the message requesting the popcat emoji, you will need to give the `The Artificer` role the `Manage Messages` permission. All other permissions needed are handled by the invite link.

## The Artificer API
|
|
The Artificer features an API that allows authenticated users to roll dice into Discord from third party applications (such as Excel macros). The API has a couple endpoints exposed to all authenticated users allowing management of channels that your API key can send rolls to. APIs requiring administrative access are not listed below.
|
|
|
|
Guilds Owners or Admins must run the `[[api allow` command for any users to be able to use the `/api/roll` endpoint.
|
|
|
|
Every API request **requires** the header `X-Api-Key` with the value set to the API key granted to you.
|
|
|
|
* If an API fails, these are the possible responses:
|
|
* `400` - Bad Request - Query parameters missing or malformed.
|
|
* `403` - Forbidden - API Key is not authenticated or user does not match the owner of the API Key.
|
|
* `404` - Not Found - Requested endpoint does not exist.
|
|
* `429` - Too Many Requests - API rate limit exceeded, please slow down.
|
|
* `500` - Internal Server Error - Something broke, if this continues to happen, please submit a GitHub issue.

## Problems? Feature requests?
|
|
If you run into any errors or problems with the bot, or think you have a good idea to add to the bot, please submit a new GitHub issue detailing it. If you don't have a GitHub account, a report command (detailed above) is provided for use in Discord.

## Self Hosting The Artificer
|
|
The Artificer was built on [Deno](https://deno.land/) `v1.7.0` using [Discordeno](https://discordeno.mod.land/) `v10.3.0`. If you choose to run this yourself, you will need to rename `config.example.ts` to `config.ts` and edit some values. You will need to create a new [Discord Application](https://discord.com/developers/applications) and copy the newly generated token into the `"token"` key. If you want to utilize some of the bots dev features, you will need to fill in the keys `"logChannel"` and `"reportChannel"` with text channel IDs and `"devServer"` with a guild ID.
|
|
|
|
You will also need to install and setup a MySQL database with a user for the bot to use to add/modify the database. This user must have the "DB Manager" admin rights and "REFERENCES" Global Privileges. Once the DB is installed and a user is setup, run the provided `db\initialize.ts` to create the schema and tables. After this, run `db\populateDefaults.ts` to insert some needed values into the tables.
|
|
|
|
Once everything is set up, starting the bot can simply be done with `deno run --allow-net .\mod.ts`.
|
|
|
|
If you choose to run version `1.1.0` or newer, ensure you disable the API in `config.ts` or verify you have properly secured your instance of The Artificer. If you enable the API, you should manually generate a 25 char nanoid and place it in `config.api.adminKey` and copy your `userid` and place it in `config.api.admin` before running `db\populateDefaults.ts`.
|
