@bender@twtxt.net It’s just a simple twtxt2html and scp … it goes like:

twtxt2html $HOME/path/to/local_twtxt_dir/twtxt.txt > $HOME/path/to/local_twtxt_dir/log.html && \
scp $HOME/path/to/local_twtxt_dir/log.html user@remotehost:/path/to/static_files_dir/

I’ve been lazy to add it to my publish_command script, now I can just copy/pasta from the twt 😅

Alright, I saw enough broken threads lately to be motivated enough to extend the --fetch-context thingy: It can now ask Yarn pods for twt hashes.

https://www.uninformativ.de/git/jenny/commit/eefd3fa09083e2206ed0d71887d2ef2884684a71.html

This is only done as a last resort if there’s no other way to find the missing twt. Like, when there’s a twt that begins with just a hash and no user mention, there’s no way for jenny to know on which feed that twt can be found, so it’ll ask some Yarn pod in that case.

In-reply-to » On the Subject of Feed Identities; I propose the following:

@mckinley@twtxt.net To answer some of your questions:

Are SSH signatures standardized and are there robust software libraries that can handle them? We’ll need a library in at least Python and Go to provide verified feed support with the currently used clients.

We already have this. Ed25519 libraries exist for all major languages. Aside from using ssh-keygen -Y sign and ssh-keygen -Y verify, you can also use the salty CLI itself (https://git.mills.io/prologic/salty), and I’m sure there are other command-line tools that could be used too.

If we all implemented this, every twt hash would suddenly change and every conversation thread we’ve ever had would at least lose its opening post.

Yes. This would happen, so we’d have to make a decision around this, either a) a cut-off point or b) some way to progressively transition.

@prologic@twtxt.net Righteo, so rookie error - I obviously had some untracked, rather important files for starting my pod and I ran a make clean. Why I originally had them in the git directory is anyone’s guess. Anyway it blew away those files including the database so that’s that. So your good self and @bender@twtxt.net etc - apologies but your profiles got nuked as well (as did my own but easily recreated).

Another thing I noticed which was the reason I ran make clean in the first place. I noticed my pod was being built with Go 1.22.4. Could this be a problem @prologic? preflight.sh actually errors out about it…

Twtxt spec enhancement proposal thread 🧵

Adding attributes to individual twts similar to adding feed attributes in the heading comments.

https://git.mills.io/yarnsocial/go-lextwt/pulls/17

The basic use case would be for multilingual feeds where there is a default language and some twts will be written a different language.

As seen in the wild: https://eapl.mx/twtxt.txt

The attributes are formatted as [key=value]

They can show up in the twt anywhere it is not enclosed by another element such as codeblock or part of a markdown link.

It takes a second on my machine and that’s with my own hashmap implementation which is probably not the fastest one.

OH MY FREAKING HECK. So.. I made my pather able to run as Dijkstra or A* if the interface includes a heuristic.. when i tried without the heuristic it finished faster :|

In-reply-to » I need to add multithreading to the desktop client, I have not done that before in c++ - so that'll be fun to figure out. I need it for the fetching of the timeline so that it happens in a separate thread. That way the GUI does not freeze while fetching the timeline. Also need to add a status bar that can show what the application is working on.

I was able to fix this now, by making a ‘default.nix’ file, and then you can open a shell that has all the stuff needed by simply typing ‘nix-shell’ in the root git directory. Pretty nice, I’m starting to enjoy this OS more and more.

I will release the sourcecode for the desktop client tonight. I will put it on github (sorry to anyone who prefer other places), but the reason is that I do not want my own git to be open for public. So I’ll put it on github where I have all my other public projects. I have to write the readme, then add some info on the login page (link to source etc), then it’s ready to release with the current features. I then hope others will give it a try and use it if they want :) I also have many other features I need to implement, but all the main features that makes it usable has been implemented, so I’m very pleased with it (And I use it all the time now).

I played around with parsers. This time I experimented with parser combinators for twt message text tokenization. Basically, extract mentions, subjects, URLs, media and regular text. It’s kinda nice, although my solution is not completely elegant, I have to say. Especially my communication protocol between different steps for intermediate results is really ugly. Not sure about performance, I reckon a hand-written state machine parser would be quite a bit faster. I need to write a second parser and then benchmark them.

lexer.go and newparser.go resemble the parser combinators: https://git.isobeef.org/lyse/tt2/-/commit/4d481acad0213771fe5804917576388f51c340c0 It’s far from finished yet.

The first attempt in parser.go doesn’t work as my backtracking is not accounted for, I noticed only later, that I have to do that. With twt message texts there is no real error in parsing. Just regular text as a “fallback”. So it works a bit differently than parsing a real language. No error reporting required, except maybe for debugging. My goal was to port my Python code as closely as possible. But then the runes in the string gave me a bit of a headache, so I thought I just build myself a nice reader abstraction. When I noticed the missing backtracking, I then decided to give parser combinators a try instead of improving on my look ahead reader. It only later occurred to me, that I could have just used a rune slice instead of a string. With that, porting the Python code should have been straightforward.

Yeah, all this doesn’t probably make sense, unless you look at the code. And even then, you have to learn the ropes a bit. Sorry for the noise. :-)

In-reply-to » First test post from GTK UI!

@prologic@twtxt.net I agree with you points, and I feel the same.
I currently run a gogs instance on my webserver, I’m putting my source there for now.
Currently registrations are disabled and such, I’m the only user, that is the main issue I think - people need to register to submit a change. and I do not want people to register on my own git instance either, so I have to think about it a bit.

Also - I would like to know where you all like to have git hosted..
Github? Some other place? Do you mind self-hosted git servers? (I currently have my own)..
What do you all prefer? Do you mind compiling software from source if instructions are clear and easy? Or do you prefer to download a released binary and run that?

I also later on (as soon as it’s in usable state) want to make flatpack, appimage as well, that is something I have not done before - but I want to set that up as well.

In-reply-to » First test post from GTK UI!

Moving my source to git today, I have just developed on a local copy until today.
I needed to move it before going too crazy with it. Starting the work on the timeline that I’ve mentioned.
Yesterday I ran out of time, but today I have some free time to work on things. Very pleased with the software already, I know I’ll use it all the time. So today I will work on refreshing the timeline, and then fix so that it’s a bit smarter then now, the class that holds the statuses will also contain the GUI elements for each status, that way I can more easily append new statuses into the timeline - instead of grabbing the whole timeline and rebuild all it’s gui each time it refreshes. I know what to do - so I do not expect it to take too long to fix.

👋 Hey y’all yarners 🤗 – @darch@neotxt.dk and I have been discussing in our Weekly Yarn.social call (still ongoing… come join us! 🙏) about the experimental Yarn.social <-> Activity Pub integration/bridge I’ve been working on… And mostly whether it’s even a good idea at al, and if we should continue or not?

There are still some outstanding issues that would need to be improved if we continued this regardless

Some thoughts being discussed:

  • Yarn.social pods are more of a “family”, where you invite people into your “home” or “community”
  • Opening up to the “Fedivise” is potentially “uncontrolled”
  • Even at a small scale (a tiny dev pod) we see activities from servers never interacted with before
  • The possibility of abuse (because basically anything can POST things to your Pod now)
  • Pull vs. Push model polarising models/views which whilst in theory can be made to work, should they?

Go! 👏
