lemmy-bot's Issues

No editComment or editPost Bot Action?

I'm looking into making a bot that lets commenters vote on what genres apply to the story and then locks it and logs it into a database that will (probably) be web-accessible.
I, admittedly, have not worked on it at all yet, but I'm imagining the comment will be updated to reflect what genres have been accepted and (maybe) a link to find more like it.

If there's no way to edit a comment via this (or any other) library, then this project will be a non-starter and probably dropped before it's even started.

[bug] federation allowList does not seem to work

The allowList property of the federation option does not seem to be followed, and the bot will reply to all comments/posts on any federated community.
example:

federation: {
  allowList: [
    {
      instance: 'lemmy.world',
      communities: ['vexillology']
    },
    {
      instance: 'lemmy.antemeridiem.xyz',
      communities: ['vexillologyjerk']
    }
  ]
},

I am using lemmy-bot 0.3.9 from npm

Get Community (and Instance) Info/Sidebar

Hi,

Can a feature be added to get the source text of a communities' (and instances') sidebar? I would like to be able to limit where my bot is run and allowing instance and community owners to set specific markdown in the sidebar seems like the easiest way to do this.

Thanks!

Getting `user_already_exists` error after login

Every login attempt results in a user_already_exists error. This probably happens in saveUserSettings() and looks like it's related to this issue, apparently one needs to include all user data in saveUserSettings().

"Removing comment ID undefined" but the ID is defined

to remove a comment I'm using

botActions.removeComment({
	reason: "Requested by user " + userName,
	removed: true,
	comment_id: parentId
});

with parentId defined, but it prints Removing comment ID undefined and does not remove the comment.

Program stops after some time with ETIMEDOUT error.

i created simple bot with posts and privateMessage handlers. After running for some time it closes with the following error:

node main.js

Node.js v21.5.0

It works for 20-30 mins before closing. One time it closed right after starting.

BotAction to follow a community

This is a feature request, it should already be possible since the code already has this:

lemmy-bot/src/bot.ts

Lines 492 to 496 in 9dfaa18

 return this.#httpClient.followCommunity({ 

 auth: this.#auth ?? '', 

 community_id, 

 follow: true 

 });

Support for the resolveObject method as a BotAction

This would allow us to find federated communities/posts/comments/people.

I currently need this to be able to find/fetch not-yet federated communities on my instance.

Database init fails on first/second try

Works fine in memory, on disk tends to take one or two start attempts for it to finish initialisation.

How to list user posts & comments ?

Hi,

I see the lib can get and edit posts and comments by ID, but what about listing IDs by user ?

Thanks

Add a dryrun mode for development

I've been doing some development on a bot, and I don't want to post my in-progress threads to a live, production lemmy instance. I'd prefer to be able to set the bot to be in "dry run" mode, and only log to the console the actions it would have taken on the production instance

The new option would be used as follows

const bot = new LemmyBot.LemmyBot({
  enableLogs: true,
  dryRun: true
});

Spam of logging in and other stuff

The exception is there too but it was big data comming up. But the "Loggin in ..... Subscribing...." is annoying me and it spams the console at start

getUserId and getCommunityId dont always find the user/community

Due to how getUserId and getCommunityId try to find the id (using the search), if the actual user or community doesnt show up in that then it cant be found by the query

For example if you try to look for the id of the community [email protected]. Doing a call to getCommunityId("git") then does an api call to https://programming.dev/api/v3/search?q=git&type_=Communities which does not have git as one of the options (instead its populated by other things that have git in the name)

Invalid JSON response body when starting up

I've got a bot for lemmy.world and it has stopped working since they've upgraded to 0.18.1-rc.4
It fails at logging in:

                                                           ^

}

I've double checked, the account credentials I'm passing in are valid.

Does not work on the new 0.18.0 update.

Hey! I haven't gotten my bot to work after updating the instance to Lemmy 0.18.0. Is this because they no longer are using websockets? If so, will this library update?

First fetch works second not anymore

I created a bot and it didnt got any posts from my community. And after i debugged it. It fetches 1 time correctly but then it doesnt fetch it anymore.

  lemmyService.bot = new LemmyBot({
          instance: process.env.LEMMY_INSTANCE!,
          credentials: {
            username: process.env.LEMMY_USERNAME!,
            password: process.env.LEMMY_PW!,
          },
          connection: {
            minutesUntilReprocess: 1,
            secondsBetweenPolls: 30,
          },
          schedule: [],
          federation: "all",
          dbFile: "./lemmy.db",
          handlers: {
post: async ({
              botActions,
              postView,
              preventReprocess,
              reprocess,
            }) => {
        console.log("NEW POST")
                  });

It logs like in the initial start the first 30 posts and then i can wait like for 15 minutes nothing happens

How to identify if a person is a mod in the community?

Is there a way to check if a person is a mod? In the "creator" variable there is just "admin" and this is not mod.

Possible spam of (almost) useless console.log

Bot creates a 502 Error

It happens when the ratelimit is achieved, it happens every time on lemmy.world and i have my poll rate at 15 ( i tested at 120 ). But it will straight up 502 Gateway Error ( Sometimes /comment sometimes /posts ) and after few seconds the login will fail too because it gets tot the ratelimit too.

I would guess the requests between comments and posts are too fast and need a buffer between them ( just use the poll rate as buffer between calls )

Tried Lemmy Instance:
lemmy.world

createComment does nothing?

I made that the bot automatically sends a message to a new post in a community. Everything works and the library replies with

"Replying to post ID 651474"

My Code:

      botActions.createComment({
                content: Config.autoComment.text,
                postId: postView.post.id,
              });

But nothing happens

0.18.1-rc.4 Is broke the bot totally

The Code i used:

const bot = new LemmyBot({
(VALID CODE)
})

bot.start()

The lemmy version is 0.18.1-rc.4

Detect if Post URL / Image / Title / Body changed?

I was wondering if Lemmy has any native ability to detect if a post was changed, and what was changed without having to store that information in an external database? If so, does lemmy-bot also have that functionality?

Unable to run bot due to issues with the examples

Hi, wondering if you could help with where I'm going wrong.

I'm using the like me bot example, and getting the error "Expected 1 arguments, but got 2. (ts2554) on the Vote.Upvote lines and the same error on the SendPrivateMessage lines where the text is flagging the same error.

I'm really new to this so most likely an error with my setup but google has been no help in figuring this out.

Thanks

edit: on Lemmy 0.18 and using bot version 0.4

"Sending private message to user ID undefined"

function onPrivateMessage(res){
	console.log(res)
	res.botActions.sendPrivateMessage(res.messageView.private_message.creator_id, "holaa")
}

this prints Sending private message to user ID undefined and does not send anything

Sometimes bot fails to start

Sometimes I'll start a script and it'll give me this error and exits. It'd be nice if it could gracefully handle this error.

I'm connecting to lemmy.world as my instance, which has weird connectivity issues. I'm wondering if the ws is timing out and actorId isn't getting set properly. If so, it would be nice if it could attempt to reconnect.

just sits at "user_already_exists"

Can't seem to get any further, it logs in, marks user as bot, and then just sits at user_already_exists

Not sure where the logs are dumped

[Feature request] Optional flag to disable logs

I don't really like having my logs spammed by the library's activity, I'd prefer handling my own logging in my app, only for the operations where I deem it necessary.

I propose creating an additional, optional flag in the new LemmyBot() constructor to disable the output of logs from the library.

If @SleeplessOne1917 likes the idea I could also implement such a feature myself and submit a PR for it.

	return this.#httpClient.followCommunity({
	auth: this.#auth ?? '',
	community_id,
	follow: true
	});
