@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.
@prologic@twtxt.net I always liked bit.
I am disappointed that a GUI app would not at least have screenshots.
One year ago to the date I made the lastest update for #phpub2twtxt to github and now 365 days later I have published #pixelblog as its successor - lets see where things are going for trip around the sun

More #pixelblog‘ing - today wotking on fixing all the semi-hardcoded paths an moving them to config.php 
#pixelblog is slowly coming together with support for posting images and simple theming 

@movq@www.uninformativ.de This is awesome! Your server/connection is slow, thought. It took ages to load the GIF! Off topic, what font are you using on that screenshot?
Added to the fun.
