eval
give an authenticated fediverse client to arbitrary javascript
the bot: @eval@beeping.town
the script:
https://pad.cosine.online/p/eval
behavior
let's call this repository the 'runner.' it is surprisingly (and increasingly) minimal
every 4 hours* the script is evaluated, and in the returned context,
interval() is called with no arguments
every time a notification is received the script is evaluated, and in the
returned context, notification(noti) is called, where noti is the
received notification
in either case, if an error is thrown either while evaluating the script or while calling the relevant function, the error and stack trace are normalized, stringified, and posted as a public status by the account
* excluding times between 1am and 7:59am Eastern Time
script context
the following identifiers (and some irrelevant ones) are provided to the script's evaluation context:
- M: the megalodon authenticated client: https://github.com/h3poteto/megalodon/tree/2.1.1
- request: npm module: https://github.com/request/request/tree/v2.88.0
- Etherpad: npm module: https://github.com/tomassedovic/etherpad-lite-client-js/tree/v0.9.0
- makePost: simple post. (text: string, spoiler_text: string) => void
- getProgram: get the contents of the etherpad. () => Promise
etherpad
the bot's script is on a text pad at https://pad.cosine.online/p/eval
this is one document on an instance of etherpad lite hosted on my server, which allows you to collaborate live with folks!
the instance
the actual runner, and therefore script, is running Node, v16.3.0
as of this writing, the script follows a general design strategy of placing functions that return text (hijinks) into an array/object, out of which one is selected at random, and has its result posted. this has proven effective for collaboration
