Say hello to `threadcat`!

@blinry that makes me want to learn Rust
@glitcx I think it's worth learning! \o/ I tried to make the code easy to read, and there's not a lot of it in this li'l project! :3

`threadcat` downloads files using their original filename on the Mastodon server. So you'll end up with a lot of files like "f55dbddca60e64cb.jpg"…
I tried deriving better filenames from the alt text – for example, taking the first two "non-filler" words from the alt text. That gives you filenames like "colorful-circles.jpg", "small-grey.jpg" or "drawing-snow.jpg", and possibly "drawing-snow-2.jpg".
Another option would just be using timestamps: "2026-04-17T13:54Z.jpg"
What do you think?
@blinry I like "non-filler words from alt text", but maybe prefix with an incremental ID so they are sorted the same as in the post?
-
Correct me if I am wrong:
You wrote a tool that enables people to download complete Mastodon threads from other participants / on other instances?
So that's NOT made for collecting OWN content, but for other people's content?
One question:
Isn't that called STEALING?
@khzimmer2 lol. read the post again. the fourth sentence

Say hello to `threadcat`! 🧶
It's a little Rust tool which takes the URL to a Mastodon thread, and converts it to a Markdown file. It also downloads all attached media files (and their alt texts)!
That way, it's really easy to get a "first draft" for a blog post from a thread you wrote!
Installation: `cargo install threadcat`
@blinry this sounds awesome. i keep wasting time copying and pasting my threads into my notes app, i will definitely try this next time

@blinry those alt text filenames are a fun and useful feature! i think a combo could be good sense, either
[post-id]-colourful-circles.jpgor[timestamp]-colourful-circles.jpg- that way it's both in some useful order and readable as well -

@blinry I have not tried using threadcat yet, but my hunch would be to keep the original filename (ensures there are no collisions) and add some metadata.
Depending on how you handle individual posts, maybe add the post ID or the ID of the anchor in your output. Having all media from a specific post in a dedicated subdirectory might be useful? -

@jer @blinry I like that too! (I have a script to generate message IDs for mails which does a similiar thing

@blinry throwing the post id in there sounds reasonable. Will threadcat also download someone else’s threads if my account is allowed to read them?

@blinry grand little tool, and just what I need to help in copy/pasting text from toots!
Could do with a Usage message, if I may say so.
$ ~/.cargo/bin/threadcat
thread 'main' (89252287) panicked at

@jpmens Already added that today!

https://codeberg.org/blinry/threadcat/commit/7aaa4daec08bc3cb1da35bf3c0cb9ac58a390953@blinry oh, I built just half an hour or so ago; must have missed it

Uhm, the poster nick before the alt-text would allow you to group images by the author, too.

@blinry I was looking for a tool like this one 2 days ago lol
-
I've been hacking on it a lot this week, with my silly human hands, and it's been a lot of fun!
Right now, it can only read threads from Mastodon, and only output Markdown, but both directions could be extended.
To try it out, I've been using it to publish one blog post each day this week – you might have noticed!

Freakin nice toolI'm on Pleroma so I'm gotta keep an eye out for when that's available

@irrlicht The Rust library I'm using even support Pleroma directly, so adding support wouldn't be that hard, I hope! \o/ https://docs.rs/megalodon/latest/megalodon/

@waffles That sounds like a tool I'd love, as well, but it seems out of scope for threadcat. Maybe something like that even already exists?
@blinry my terrible memory recalls something like that, but I never really trust “flash in the pan” abandonware, so I was casually hopeful that yours might serve
Anyways, congrats on the new project!
