ZIG
Zig is a simple data format. It is designed to be edited by hand. It is also pretty easy to parse and generate, though. You can think of Zig as an alternate, indentation-based syntax for JSON.
Here is a short example that shows all data structures:
{
type: 'error'
subtype: nil
description: "
Check your Internet connection. Restart any router, modem,
or other network devices you may be using.
color: {
r: 255
g: 192
b: 0
# TODO: do we need these any more?
flags: [
true
false
true
In order of appearance: hash, string, nil, multiline string, number, comment, list, boolean.
