Was a bit late with posting the solution thread and solving this since I ended up napping until 2am, if anyone notices theres no solution thread and its after the leaderboard has been filled (can check from the stats page if 100 people are done) feel free to start one up (I just copy paste the text in each of them)

So, how does one create a Lemmy bot? in c/[email protected]

[–] [email protected] 5 points 1 year ago* (last edited 1 year ago) (2 children)

Theres a lot of different frameworks to use for creating them

The most popular one is lemmy-bot which uses js (and has descriptions for how to use it on the page)

Theres also one in python though here with a couple examples in its repo

🎁 - 2023 DAY 5 SOLUTIONS -🎁 in c/[email protected]

[–] [email protected] 1 points 1 year ago

Turns out I got really lucky and my location value is much lower than most peoples which is why it can be solved relatively quickly

🎁 - 2023 DAY 5 SOLUTIONS -🎁 in c/[email protected]

[–] [email protected] 5 points 1 year ago* (last edited 1 year ago) (3 children)

[JavaScript] Well that was by far the hardest out of all of the days, part 1 was relatively fine but part 2 took me awhile of trying different things

Ended up solving it by working backwards by trying different location values and seeing if that can become a valid seed. Takes around 3 secs to compute the answer.

Very basic help needed with TextureButton in c/[email protected]

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago) (1 children)

Yeah, if that's causing the issue you might be running into a case where when trying to make the image smaller it ends up not having enough pixels to show the border properly. Typically people make textures the size of what they want the final texture size to be rather than messing with proportions afterwards due to things like that (and so you don't have to store larger images than required)

To make it go smaller tick the ignore texture size box

That will make it so you can force it past the texture size

Very basic help needed with TextureButton in c/[email protected]

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago) (5 children)

the keep aspect covered is similar but one side will clip out while the other is the right size, and keep aspect with no modifier (and centered) will fit but not take the full button (it will take as much as it can without destroying the texture)

if theres issues with it appearing and you have scale set it might be something to do with the border being too small or sizes being a bit wonky so that it tries to take up the full space but it goes out of the bounds of the parent

I would try it with just a texturebutton like I did there with nothing else as the parent (or a basic control) and just set stretch mode and normal texture and see what happens

Stretch mode scale should do that, its what it was made for. The only things I changed are the two you can see on the right there

Improvement I found afterwards:

Could have done a reduce on the amount array instead of the lines array since I don't use the line value at all

The RemindMe Bot! A lemmy bot that reminds you after an amount of time (github.com)

submitted 2 years ago* (last edited 2 years ago) by [email protected] to c/[email protected]

14 comments fedilink

Im currently hosting this bot here on programming.dev and have it set to federate with everything programming.dev does so you dont need to self host

To trigger the bot just tag @[email protected] at the start of your comment and then put the amount of time you want to be reminded in

Supports everything from seconds to years up to a maximum of 10 years
Supports other activitypub platforms as long as they can make a message in lemmy (ex. mastodon)

If you have any improvements or suggestions feel free to make an issue/pull request in the repo

~~Edit: Now works based on keywords so you can summon it with !remindme instead of a full ping~~ See edit 4

~~Edit 2: Kbin seems to break it if your comment doesnt have language set to english. Not something I can fix, kbin is going to have to~~ See edit 3

Edit 3: Ive fixed the kbin bug for all communities in the instance. No promises if it doesnt respond in a non programming.dev instance though as their language settings may be different and block replies to your comments

Edit 4: The bot is temporarily offline so I can make it follow the lemmy.world bot guidelines

The Guardian Bot: A lemmy bot that deletes messages containing blacklisted links (github.com)

submitted 2 years ago by [email protected] to c/[email protected]

0 comments fedilink

This is a bot I made for the programming books community here on programming.dev to prevent pirating but can be adapted to any community.

It has functionality for both a whitelist and a blacklist and has templates so you can share ban lists between communities. It also detects in both posts and comments

Since it deals with deleting messages it needs mod permissions in communities you want to use it for

Feel free to dm me if you need some help with getting it set up

Welcome to the programming books community! (programming.dev)

This is a place where you can share and discuss books relating to the instance

Links are currently disabled in the community. If you have a domain that you feel should be whitelisted feel free to let me know and ill add it. (This rule is just in place to prevent pirating books)

And if you want to be a mod for the community let me know

The lemmy rss feed bot has been updated to handle V0.18 (github.com)

submitted 2 years ago* (last edited 2 years ago) by [email protected] to c/[email protected]

0 comments fedilink

The bot api got updated so updated my rss feed bot to V0.18 as well

It auto posts new things from rss feeds into communities. I currently have it set up in [email protected] [email protected] and [email protected] posting official news from the engines and some other people are using it as well (one having adapted it to post news from their city)

If you want to set it up and are having issues feel free to ask me about it.

In this update theres also some other things about the bot that have changed

Data is now pulled from a yaml file so its easier to deal with as opposed to digging through the javascript code in order to change stuff
Important values such as how long the bot will wait before checking for new posts have been parameterized
You can now post things that are in two rss feeds or in one rss feed but not another if you want to filter posts down a bit more
You can set a date cutoff for how long ago you want to backpost posts from
