# Botodon

A pretty simple random message bot using [Mastodon](https://joinmastodon.org) statuses as source of truth.

- **no database:** store volatile data in statuses
- **easy edit:** allows easy edit from web ui or apps.
- **community:** allows public submit with strict or community driven moderation

## Install
### Mastodon

- Create an account for this bot. Please mark it as bot in configuration page.
- In settings page, create a new application with read write permission and copy the private key.
- Create a status to store actions (could be private) and copy its id. *Called `root status` after*
- Create a status to store content (could be private) and copy its id. *Called `data status` after*
  - Reply to this status to add content. (Removing @acct, to limit self spam)
- Reply to `root status` with options tags *(See `action status`)* like `#botodon #global #data_from_{DATA_STATUS_ID}`

### Botodon

```sh
git clone <url> botodon
cd botodon
npm install
cp .env.sample .env
```

In `.env` set
- `DOMAIN={INSTANCE_DOMAIN}`
- `TOKEN={ACCOUNT_PRIVATE_KEY}`
- `ROOT_STATUS={ROOT_STATUS_ID}`

Run `npm run start` with cron.

Enjoy

## Main ideas

It uses statuses tags as configuration like `#xxx_yyy`. So content doesn't really matter except obviously for `content statuses`

There is 3 *types* of statuses:

- *The* `root status` contains global options. See [Root status](#root-status)
- `action status` contains action to run and is descendant of `root status`. See [Action status](#action-status)
- `data status` is a data source like a folder containing `content statuses`
- `content status` is a *normal* status its content *(including medias)* will send

### Root status

Its a folder containing `action statuses` and global options as tags.

tag | description
-- | --
botodon | **Required** Enable tags processing
async | Enable actions parallel processing
deep | Use replies to actions as actions
shared | **Unsafe** Include other users actions

### Action status

## Limits

Mastodon context API use an arbitrary limit of `4096` since [#7564](https://github.com/tootsuite/mastodon/pull/7564), it's so the limit were new replies are excluded.

Followers soft limit of `999` *(must include pagination)* and hard limit of `7500`.

## TODO

- Add abstract and inherit on deep actions
- Add actions time validators
- Use followers pagination
- Add options on `data status`
- Add move pick options
