@itsericwoordward@itsericwoodward.com I just want to let you know that your mention completion seems to be broken. :-) The URL is duplicated with a comma in between. Actually, the protocols differ. I suspect that you extract all url metadata fields from the feed, not only the canonical one used for hashing (the first one) and join them. I’m not completely sure, I would need to read up on the specs (it’s already past bed o’clock, though), but I guess that there is no explicit rule for picking the mention URL. Without having thought about it too much, I reckon the safest bet is to stick to the hashing URL when in doubt and the URL that was used to subscribe to the feed is not available for whatever reason. The URL from the subscription list is probably even better.

[$] Trying to make sense of package-manager metadata
Package managers for operating systems and programming languages have been
around for decades. Each package manager, and its accompanying packaging format,

example, in vulnerability scans, software bills of materials (SBOMs), and more. On

@prologic@twtxt.net @bender@twtxt.net Thanks! Yeah, it already supports Twt Hash via twtxt-lib (both v1 and v2, when the time is right), plus most of the other features (multiline, user-agent, and metadata), and I’m working on (re-)implementing threading, mentions, and hash filtering (to make conversations easier to follow).

Here’s a current snapshot of my local version, in case anyone is interested:

[$] Tagging music with MusicBrainz Picard
Part of the “fun” that comes with curating a self-hosted music library is tagging

open-source tools to make this process easier. One of the best, or at least my

I think I’m just about ready to go live with my new blog (migrated from MicroPub). I just finished migrating all of the content over, fixing up metadata, cleaning up, migrating media, optimizing media.

The new blog for prologic.blog soon to be powered by zs using the zs-blog-template is coming along very nicely 👌 It was actually pretty easy to do the migration/conversation in the end. The results are not to shabby either.

Before:

• ~50MB repo
  
• ~267 files
  

After:

• ~20MB repo
  
• ~88 files

@bender@twtxt.net Ahh yes I see what you mean. no indicate of when the post was made right? That should be ideally displayed on the page somewhere? Would you expect it in the url as well, because not having /posts/yyyy/mm/dd/.... was actually intentional. But yeah I should figure out where to put some additional metadata on the page.

@zvava@twtxt.net Good question. This is the spec, I think:

https://twtxt.dev/exts/metadata.html#nick

It doesn’t say much. 🤔

In the wild, I’ve only seen “traditional” nick names, i.e. ASCII 0x21 thru 0x7E.

My client removes anything but r'[a-zA-Z0-9]' from nick names.

@dce@hashnix.club Ah, oh, well then. 🥴

My client supports that, if you set multiple url = fields in your feed’s metadata (the top-most one must be the “main” URL, that one is used for hashing).

But yeah, multi-protocol feeds can be problematic and some have considered it a mistake to support them. 🤔

@prologic@twtxt.net Yeah, this really could use a proper definition or a “manifest”. 😅 Many of these ideas are not very wide spread. And I haven’t come across similar projects in all these years.

Let’s take the farbfeld image format as an example again. I think this captures the “spirit” quite well, because this isn’t even about code.

This is the entire farbfeld spec:

farbfeld is a lossless image format which is easy to parse, pipe and compress. It has the following format:

╔════════╤═════════════════════════════════════════════════════════╗
║ Bytes  │ Description                                             ║
╠════════╪═════════════════════════════════════════════════════════╣
║ 8      │ "farbfeld" magic value                                  ║
╟────────┼─────────────────────────────────────────────────────────╢
║ 4      │ 32-Bit BE unsigned integer (width)                      ║
╟────────┼─────────────────────────────────────────────────────────╢
║ 4      │ 32-Bit BE unsigned integer (height)                     ║
╟────────┼─────────────────────────────────────────────────────────╢
║ [2222] │ 4x16-Bit BE unsigned integers [RGBA] / pixel, row-major ║
╚════════╧═════════════════════════════════════════════════════════╝

The RGB-data should be sRGB for best interoperability and not alpha-premultiplied.

(Now, I don’t know if your screen reader can work with this. Let me know if it doesn’t.)

I think these are some of the properties worth mentioning:

• The spec is extremely short. You can read this in under a minute and fully understand it. That alone is gold.
  
• There are no “knobs”: It’s just a single version, it’s not like there’s also an 8-bit color depth version and one for 16-bit and one for extra large images and one that supports layers and so on. This makes it much easier to implement a fully compliant program.
  
• Despite being so simple, it’s useful. I’ve used it in various programs, like my window manager, my status bars, some toy programs like “tuxeyes” (an Xeyes variant), or Advent of Code.
  
• The format does not include compression because it doesn’t need to. Just use something like bzip2 to get file sizes similar to PNG.
  
• It doesn’t cover every use case under the sun, but it does cover the most important ones (imho). They have discussed using something other than RGBA and decided it’s not worth the trouble.
  
• They refrained from adding extra baggage like metadata. It would have needlessly complicated things.

PEP 794: Import Name Metadata
This PEP proposes extending the core metadata specification for Python packaging to include a new, repeatable field named Import-Name to record the import names that a project owns once installed.

@eapl.me@eapl.me Neat.

So for twt metadata the lextwt parser currently supports values in the form [key=value]

https://git.mills.io/yarnsocial/go-lextwt/src/branch/main/parser_test.go#L692-L698

@eapl.me@eapl.me here are my replies (somewhat similar to Lyse’s and James’)

1. Metadata in twts: Key=value is too complicated for non-hackers and hard to write by hand. So if there is a need then we should just use #NSFS or the alt-text file in markdown image syntax ![NSFW](url.to/image.jpg) if something is NSFW

2. IDs besides datetime. When you edit a twt then you should preserve the datetime if location-based addressing should have any advantages over content-based addressing. If you change the timestamp the its a new post. Just like any other blog cms.

3. Caching, Yes all good ideas, but that is more a task for the clients not the serving of the twtxt.txt files.

4. Discovery: User-agent for discovery can become better. I’m working on a wrapper script in PHP, so you don’t need to go to Apaches log-files to see who fetches your feed. But for other Gemini and gopher you need to relay on something else. That could be using my webmentions for twtxt suggestion, or simply defining an email metadata field for letting a person know you follow their feed. Interesting read about why WebMetions might be a bad idea. Twtxt being much simple that a full featured IndieWeb sites, then a lot of the concerns does not apply here. But that’s the issue with any open inbox. This is hard to solve without some form of (centralized or community) spam moderation.

5. Support more protocols besides http/s. Yes why not, if we can make clients that merge or diffident between the same feed server by multiples URLs

6. Languages: If the need is big then make a separate feed. I don’t mind seeing stuff in other langues as it is low. You got translating tool if you need to know whats going on. And again when there is a need for easier switching between posting to several feeds, then it’s about building clients with a UI that makes it easy. No something that should takes up space in the format/protocol.

7. Emojis: I’m not sure what this is about. Do you want to use emojis as avatar in CLI clients or it just about rendering emojis?

So, @prologic@twtxt.net, Yarn isn’t rendering the metadata as described on the format documentation. That is, ux2028 is ignored when Yarn renders the description metadata.
