Thatās what Iām using right now, while my own client is still in the making.
A simple bash script to write a post in a mktemp file then clean it with regex.
I donāt even bother to hash the replies, I just open https://twtxt.net and copy the hash by hand since Iām checking the new posts from there anyway (temporarily, as I might end up DoS-ing everyoneās feed in my client right now).
@zvava@twtxt.net I axtually latest did and I wasnāt the only one š¤£
@zvava@twtxt.net Thatās what Iām leaning towards yeahš¤
@prologic@twtxt.net to clarify: i meant the ability to parse feeds using unix command line utilities, as a principal of twtxtv1ās design. im not sure how feasible it is to build a simple feed reader out of common scripting utilities when hashing is in play, and;
i concede, it does make a lot of sense to fix up the hashing spec rather than completely supplant it at this point, just thinking about what the rewrite would be like is dreadful in and of itself x.x
And I need to make something absolutely clear as well here. Twtxt was completely and utterly dead back in {Aug 2020](https://yarn.social/about.html) when I came across the spec and its simplicity and realised the lost opportunity. Since then weāve continued to grow a small but thriving community. The extensions weāve built over time have stood and lasted the test of time for the past ~5 years. We need not break things too badly, because what we have today and was designed years ago actually works quite well⢠(despite some flaws).
@zvava@twtxt.net Going to have to hard disagree here Iām sorry. a) no-one reads the raw/plain twtxt.txt files, the only time you do is to debug something, or have a stick beak at the comments which most clients will strip out and ignore and b) Iām sorry youāve completely lost me! Iām old enough to pre-date before Linux became popular, so Iām not sure what UNIX principles you think are being broken or violated by having a Twt Subject (Subject) whose contents is a cryptographic content-addressable hash of the āthingā⢠youāre replying to and forming a chain of other replies (a thread).
Iām sorry, but the simplest thing to do is to make the smallest number of changes to the Spec as possible and all agree on a āMagic Dateā for which our clients use the modified function(s).

@prologic@twtxt.net the simplest thing to do is to completely forgo hashing anything because we are communicating using plain text files right now :3 while i agree hashes are incredibly helpful in the backend im not sure it has a place outside of it, it basically eliminates two core design principals of twtxt (human readability and integrating well with unix command line utilities) and makes new clients more difficult to build than it should be
@bender@twtxt.net Well honestly, this is just it. My strong position on this is quite simple:
Do the simplest thing that could work.
Itās one of the age old UNIX philosphies.
Therefore, the simplest thing⢠to do here is to just increase the hash length, mark a magic⢠date/time as @lyse@lyse.isobeef.org has indicated and call it a day. Weāll then be fine for a few hundred years, at which point thereāll be no-one left alive to give a shit⢠anyway š¤£
@prologic@twtxt.net considering other alternatives we have seeing (of which I have lost track already), yes. Why donāt you guys (client makers) take a step at a time and, for now, increase the hash length to deal with the collisions. Then location-based addressing can be added⦠or not, you know. š
@alexonit@twtxt.alessandrocutolo.it My problem is I donāt see a world where we donāt employ some form of cryptography to use as keys for threads in databases and other such things honestly. Iām not going to use url#timestamp as keys.

Each origin feed numbers new threads

Each origin feed numbers new threads

This is possibly the only other threading model I can come up with for Twtxt that I think I can get behind.
Each origin feed numbers new threads
(tno:N). Replies carry both (tno:N) and (ofeed:<origin-url>). Thread identity = (ofeed, tno).
Example:

@alexonit@twtxt.alessandrocutolo.it Maybe I misunderstood, but you have to keep the timezone offsets in mind. Simple alphabetical sorting of the timestamp strings does not yield a truly chronological order. It might be close enough for you, though.
@alexonit@twtxt.alessandrocutolo.it that sounds pretty much like Italy! LOL. We pay $48 on renewal in Florida, US, but that fee isnāt Federal, so other states may pay more, or less.

@alexonit@twtxt.alessandrocutolo.it Yhays kind of love you!! Stance and position on this. If we are going to make chicken changes in the threading model, letās keep content based addressing, but also improve the use of experience. So in fact, in order to answer your question, I think yes, we can do some kind of combination of both.
@lyse@lyse.isobeef.org I donāt think thereās any point in continuing the discussion of Location vs. Content based addressing.
I want us to preserve Content based addressing.
Letās improve the user experience and fix the hash commission problems.
@aelaraji@aelaraji.com welcome back dude! Long time no see!
@movq@www.uninformativ.de Yeah, it took quite some time to load. But then it was briefly back. Now itās 503ing immediately all the time.

@lyse@lyse.isobeef.org šæšæšæš
@movq@www.uninformativ.de Woah, cool!
(WTF, asciiworld-sat-track somehow broke, but I have not changed any of the scripts at all. O_o It doesnāt find the asciiworld-sat-calc anymore. How in the world!? When I use an absolute path, the .tle is empty and I get a parsing error. Gotta debug this.)
@prologic@twtxt.net I know we wonāt ever convince each other of the otherās favorite addressing scheme. :-D But I wanna address (haha) your concerns:
I donāt see any difference between the two schemes regarding link rot and migration. If the URL changes, both approaches are equally terrible as the feed URL is part of the hashed value and reference of some sort in the location-based scheme. It doesnāt matter.
The same is true for duplication and forks. Even today, the ācannonical URLā has to be chosen to build the hash. Thatās exactly the same with location-based addressing. Why would a mirror only duplicate stuff with location- but not content-based addressing? I really fail to see that. Also, who is using mirrors or relays anyway? I donāt know of any such software to be honest.
If there is a spam feed, I just unfollow it. Done. Not a concern for me at all. Not the slightest bit. And the byte verification is THE source of all broken threads when the conversation start is edited. Yes, this can be viewed as a feature, but how many times was it actually a feature and not more behaving as an anti-feature in terms of user experience?
I donāt get your argument. If the feed in question is offline, one can simply look in local caches and see if there is a message at that particular time, just like looking up a hash. Whereās the difference? Except that the lookup key is longer or compound or whatever depending on the cache format.
Even a new hashing algorithm requires work on clients etc. Itās not that you get some backwards-compatibility for free. It just cannot be backwards-compatible in my opinion, no matter which approach we take. Thatās why I believe some magic time for the switch causes the least amount of trouble. You leave the old world untouched and working.
If these are general concerns, Iām completely with you. But I donāt think that they only apply to location-based addressing. Thatās how I interpreted your message. I could be wrong. Happy to read your explanations. :-)

@alexonit@twtxt.alessandrocutolo.it Personally, I find the reversed order of URL first and then timestamp more natural to reference something. Granted, URL last would be kinda consistent with the mention format. However, the timestamp doesnāt act as a link text or display text like in a mention, so, itās some different in my opinion. But yeah.

nicks? i remember reading somewhere whitespace should not be allowed, but i don't see it in the spec on twtxt.dev ā in fact, are there any other resources on twtxt extensions outside of twtxt.dev?
@zvava@twtxt.net In tt, I recognize umlauts in nicks, but they cannot include whitespace, @, !, #, (, ), [, ], <, >, " (but ' is okay). Whitespace also acts as a separator between nick and URL. @<Hello World http://example.com> ends up exactly like that and is not a mention.
@zvava@twtxt.net @lyse@lyse.isobeef.org I also think a location based reference might be better.
A thread is a single post of a single feed as a root, but the hash has the drawback of not referencing the source, in a distributed network like twtxt it might leave some people out of the whole conversation.
I suggest a simpler format, something like: (#<TIMESTAMP URL>)
This solves three issues:
- Easier referencing: no need to generate a hash, just copy the timestamp and url, itās also simpler to implement in a client without the rish of collisions when putting things together
- Fetchable source: you can find the source within the reference and construct the thread from there
- Allow editing: If a post is modified the hash becomes invalid since it depends on
[ timestamp, url, content ]
Hello everyone! š
After a long while away, Iām back on twtxt with this new feed.
Some of you might remember me as justamoment@twtxt.net, that was a test account I made for trying things out, but I ended up keeping it more than planned.
I also tried other social platforms in search of a place that felt right for me.
In the end twtxt was the one that ticked all of my boxes:
- Slow social: it act more like a feed reader and I really appreciate that thereās no flood of content that I canāt keep up with.
- No server needed: I absolutely love to have total control over my content, I tend to avoid having moving parts that might break, plus you can put your feed under version control and itās all backed up.
- Ownership: I can put my feed anywhere I want and nobody can decide if I can access it or not.
- For hackers: a single .txt file allows me to join a community, how cool is that!
This is why I decided to build my own twtxt client, one that allows you to decide how the feed is presented on your āinstanceā.
Itās still in the making but Iāll try to share a bit of it once I defined how things should work.
Coincidentally, I discovered that @itsericwoodward@itsericwoodward.com and @zvava@twtxt.net were also building a twtxt client, seems like twtxt is set to grow!
@bender@twtxt.net Soon soonš¤£
@prologic@twtxt.net ah! Well, keeping fingers crossed for you and family on that RV, for sure! š¤š»
@bender@twtxt.net I wish 𤣠Nah work on-site thingyš
@prologic@twtxt.net ah, I was wondering! Hoping you are having a good time, mate! Christening the new RV? :-)
@movq@www.uninformativ.de Mit Code. Aber ich habe da echt so einen knoten im Kopf. Die Beispiele in meiner Filterblase helfen mir auch nicht.
Dann kommt das eben in die Kiste mit den unfertigen Dingen.
https://andros.dev/texudus.txt, its url doesn't correspond to the feed either
I know it doesnāt need to be said, but āTexudusā is not twtxt. It is an attempt to create a, arguably, ābetter wayā¢ļøā. š¤
https://andros.dev/texudus.txt, its url doesn't correspond to the feed either
@zvava@twtxt.net ah, yes, thatās the only Texudus feed. It also seems it is a one way only feed.
@bender@twtxt.net https://andros.dev/texudus.txt, its url doesnāt correspond to the feed either
/^([-_\p{N}\p{L}])+$/iu because i don't like how english-centric only allowing ascii letters/numbers is though this only applies to local users as of now, currently all nicknames are tolerated when parsing remote feeds and i just do mentions how yarn does (just the feed url)
@zvava@twtxt.net which Texodus feed? That I know of, there is only one, or am I wrong?
nicks? i remember reading somewhere whitespace should not be allowed, but i don't see it in the spec on twtxt.dev ā in fact, are there any other resources on twtxt extensions outside of twtxt.dev?
@lyse@lyse.isobeef.org @movq@www.uninformativ.de bbycllās nickname regex is /^([-_\p{N}\p{L}])+$/iu because i donāt like how english-centric only allowing ascii letters/numbers is though this only applies to local users as of now, currently all nicknames are tolerated when parsing remote feeds and i just do mentions how yarn does (just the feed url)
in the wild, iāve noticed a texedus feed with spaces in the nick (where its spec explicitly disallows whitespace in the nick) and feeds with other symbols in the nick too. honestly, i think we should just tolerate arbitrary nicknames for sake of user expression (while stripping or converting unreasonable characters) and just leave them out of mentions
nicks? i remember reading somewhere whitespace should not be allowed, but i don't see it in the spec on twtxt.dev ā in fact, are there any other resources on twtxt extensions outside of twtxt.dev?
@zvava@twtxt.net @movq@www.uninformativ.de Iām not entirely sure about the spaces, but maybe they were omitted to simplify parsing of mentions in the form of @<nick url>. If the next token after the @<nick does not look like a URL, itās not a mention but regular text. This is just wild guessing, though.
Looking at the regex and tests in the original twtxt reference implementation seems to confirm that theory in the sense as it relies on whitespace as the delimiter:
https://lyse.isobeef.org/tmp/screenshot-2025-09-17-21-30-25.png
Another thing about nicks is that the original twtxt reference implementation converts nicks to all lowercase:
https://lyse.isobeef.org/tmp/screenshot-2025-09-17-21-20-39.png
You probably know this already, the original twtxt file format specification can be found here: https://twtxt.readthedocs.io/en/latest/user/twtxtfile.html
As for extensions, I donāt know of anything outside of twtxt.dev that has actually been (partially) implemented. However, there is also the issue tracker of the official reference implementation. You might wanna dig through that. For example, there is an alternative suggestions of multiline messages: https://github.com/buckket/twtxt/issues/157
@arne@uplegger.eu Hm, noch nie gemacht. š¤ Machst du das von Hand oder mit Code?
nicks? i remember reading somewhere whitespace should not be allowed, but i don't see it in the spec on twtxt.dev ā in fact, are there any other resources on twtxt extensions outside of twtxt.dev?
@zvava@twtxt.net Good question. This is the spec, I think:
https://twtxt.dev/exts/metadata.html#nick
It doesnāt say much. š¤
In the wild, Iāve only seen ātraditionalā nick names, i.e. ASCII 0x21 thru 0x7E.
My client removes anything but r'[a-zA-Z0-9]' from nick names.
is there consensus on what characters should(nāt) be allowed in nicks? i remember reading somewhere whitespace should not be allowed, but i donāt see it in the spec on twtxt.dev ā in fact, are there any other resources on twtxt extensions outside of twtxt.dev?
@kat@yarn.girlonthemoon.xyz, this one, regarding āAnubisā (which I believe you use, right?): https://github.com/eternal-flame-AD/pow-buster
@kat@yarn.girlonthemoon.xyz, see this one, regarding āAnubisā (which I believe you use, right?): https://github.com/eternal-flame-AD/pow-buster
@lyse@lyse.isobeef.org Omg, that is great. š
@zvava@twtxt.net There would be only one hash for a message. Some to be defined magic date selects which hash to use. If the message creation timestamp is before this epoch, hash it with v1, otherwise hammer it through v2. Eventually, support for v1 could be dropped as nobody interacts with the old stuff anymore. But Iād keep it around in my client, because why not.
If users choose a client which supports the extensions, they donāt have to mess around with v1 and v2 hashing, just like today.
As for the school of thought, personally, Iād prefer something else, too. Iām in camp location-based addressing, or whatever it is called. There more I think about it, a complete redesign of twtxt and its extensions would be necessary in my opinion. Retrofitting has its limits. Of course, this is much more work, though.
@thecanine@twtxt.net Id like that too, it just canāt come from me, because native mobile dev just isnāt my thing š¢
@zvava@twtxt.net And yes yarnd does have a well documented API and two clients (CLI and unmaintained Flutter App)
@zvava@twtxt.net We can do that š
@zvava@twtxt.net Not much of a known fact these days, but thereused to be a Yarn phone app (https://git.mills.io/yarnsocial/app), last version released 5 or so years ago, but it still suggests, it has to be somewhat feasable, to make another one. I donāt think anyone tried since, because the web version works well on phones, but Iām still hoping, we get a more native phone experience, one day.
@lyse@lyse.isobeef.org i dont mind if the hash is not backward compatible but im not sure if this is the right way to proceed because the added complexity dealing with two hash versions isnt justified
regular end users wont care to understand how twt hashes are formed, they just want to use twtxt! so i guess i could work in protecting users from themselves by disallowing post edits on old posts or posts with replies, but iām not fond of this either really. if they want to break a thread, they can just delete the post (though iāve noticed yarn handling post deletes dubiouslyā¦)
on activitypub i do genuinely find myself looking through several month or even year old posts sometimes and deciding to edit/reword them a little to be slightly less confusing, this should be trivial to handle on twtxt which is an infinitely simpler specification
@bender@twtxt.net @thecanine@twtxt.net well now this has me thinking abt the feasibility of making an android twtxt app for pods, the actual apis of pods would have to be standardized (or the fucked up way that activitypub does it, where the āmastodon apiā is the defacto client api (does yarn even have an api reference?)) or the client is just simply..a client..but editing feeds via PUT, PATCH, DELETE etc. is standardized!ā¦? (not to mention i dont even know where to begin making an android app lmao)
Wanting to add, this isnāt a twtxt client. It is Yarnd on steroids! š
@thecanine@twtxt.net it should work everywhere. It is a web application.
@zvava@twtxt.net love the direction this is heading, hope this soon evolves into a basic Android app, usable with any instance.
@lyse@lyse.isobeef.org I didnāt know they had a name, to be honest. When I/we last had a dot matrix printer, I just sat alone in the basement and made these. š
@bender@twtxt.net Sigh. So itās just me. Again. š
[2025/09/11 12:56:01.816] ā please set config.host when trying to run "bbycll". How to bypass that tiny hurdle?
Adding too this. The configuration example at the repository reads:
{
"nick": "Example",
"description": "alice's twtxt instance!",
"host": "twtxt.example.com",
"admin": "alice"
}
Would it make more sense changing nick to instance_name or similar? Usually nick is reserved for users, like here, quark. Right? Also, is host the same FQDN to be used while proxying traffic to the application? That is, using the above configuration, itās Caddy configuration would be:
twtxt.example.com {
encode
reverse_proxy :31212
}
Is that correct?
