i have finished porting my laptop config to nixos in record time. i did the entire rebuild in one day, only a handful of hours total. love it.

I have figured out how to configure my twtxt config so that I can make slightly longer posts.

@bender@twtxt.net Yeah I’ve been having this problem for quite sometime now. It boils down to Vi/Vim/NeoVim inserting those line breaks automatically when editing an .eml file (if I can remember the file extension correctly) … I think Jenny makes use of those. I had to delete them manually until I was told that the problem was fixed after I added the charset utf-8; to my nginx config file. I’ll try and fix this next…

@lyse@lyse.isobeef.org its a hierarchy key value format. I designed it for the network peering tools i use.. I can grant access to different parts of the tree to other users.. kinda like directory permissions. a basic example of the format is:

@namespace
# multi
# line
# comment
root :value

# example space comment
@namespace.name space-tag 

# attribute comments
attribute attr-tag  :value for attribute

# attribute with multiple 
# lines of values
foo :bar
      :bin
      :baz

repeated :value1
repeated :value2

each @ starts the definition of a namespace kinda like [name] in ini format. It can have comments that show up before. then each attribute is key :value and can have their own # comment lines.
Values can be multi line.. and also repeated..

the namespaces and values can also have little meta data tags added to them.

the service can define webhooks/mqtt topics to be notified when the configs are updated. That way it can deploy the changes out when they are updated.

Yeah, the lack of comments makes regular JSON not a good configuration format in my view. Also, putting all keys in quotes and the use of commas is annoying. The big upside is that’s in lots of standard libraries.

I think the appeal with YAML is that is has comments, is kind of easy to write and read and also provides unlimited nesting levels. But it has all its drawbacks, no question. Forbidding tabs, thousands of different string flavors, having so many boolean options (poor Norwegians) etc. I use it, but I don’t particularly enjoy it.

Among simple key value pairs, I like INI files, but with # for comments, not ;. I never used TOML, read up on it yesteray before writing this question, but it looks a bit weird and has some strange rules. I guess I have to give it a try one day.

And yes, as mentioned by several of you, it always depends on the complexity of the configuration at hand.

I’m developing something for the scouts at the moment with rather simple requirements on the config. Currently, there are just four settings. Even INI would be overkill with its section. I selected JSON for now, because that’s readily available with Go’s std lib. But I do not like it.

Btw. what’s your own config format, @xuu@txt.sour.is?

I’d love to read the original source code of this:

https://ecsoft2.org/t-tiny-editor

This was our standard editor back in the day, not an “emergency tool”. And it’s only 9kB in size … which feels absurd in 2023. 😅 The entire hex dump fits on one of today’s screens.

Being so small meant it had no config file. Instead, it came with TKEY.EXE, a little tool to binary-patch T.EXE to your likings.

Doesn’t even compile on my system, which is apparently broken:

A GTK 4 application showing an empty window uses about 160 MB of RAM:

$ wget https://movq.de/v/138ab3e622/win.c
$ cc -Wall -Wextra -o win win.c $(pkg-config --cflags --libs gtk4)
$ ./win

It also takes several seconds to start on my machine because it is compiling shaders and initializing DRI (it’s faster on the second run, unless you happen to lose ~/.cache/mesa_shader_cache/). This might be a hint as to why it’s using so much memory: There’s obviously much more going on behind the scenes these days, not just a little bit of internal housekeeping and then creating a window.

I learned how to make gopls syntax highlight go templates in VSCodium.

By adding the following to my config

i could go from into

Great, last system update broke something, building from current master I get:

/usr/bin/ld: /lib/x86_64-linux-gnu/libm.so.6: unknown type [0x13] section `.relr.dyn'

What the heck!?

And it also appears that I’m not really able to reproduce this unread bug. It only kind of works a single time. And it has something to do with my config. Not sure what it is yet. I also noticed that the <updated> timestamps in the entries somehow shifted between the old and new feed. Da fuq!?

oh wow.. no clue. maybe a config issue where its loading the webassm from a different domain? https vs http even?

@prologic@twtxt.net what Content-Security-Policy should I have on my web server for salty? the frontend ain’t reacting well to my global config lol

evalerror: refused to create a webassembly object because ‘unsafe-eval’ is not an allowed source of script in the following content security policy directive: “default-src ‘self’”.

@lyse@lyse.isobeef.org Yes, I have LANG=en_US.UTF-8 on my system. So, it is not that it can’t find the config?

@prologic@twtxt.net Could the config be embeded into the head comment of the twtxt.txt file and parsed out? If it also had an avatar: field that pointed to where the avatar image is located it can be almost all self contained.
