Indention or Double Brackets for Super INI

superini.md

[section]

  [subsection1]
  key1=value1
  key2=value2

  [subsection2]
  key1=value1
  key2=value2

or

[section]

[[subsection1]]
key1=value1
key2=value2

[[subsection2]]
key1=value1
key2=value2

; Doesn't this already work?
[section "subsection1"]
key1=value1
key2=value2

[section "subsection2"]
key1=value1
key2=value2

I should clarify that I mean nested sections. My examples would translate to JSON as:

{ "section" => { "subsection1" => { "key1"=>"value1", "key2"=>"value2" },
                 "subsection2" => { "key1"=>"value1", "key2"=>"value2" } } }

But now that I look at your example again, maybe that's what you meant too. I have just never seen that notation before and there seems to be no mention of it on Wikipedia.

Note, TOML is using something similar:

[section.subsection1]
key1=value1
key2=value2

[section.subsection2]
key1=value1
key2=value2

@trans, look in any Git config file. Those are INI, albeit yet another special version of INI.

This doesn't really nest in any way that I can see.

Also take a look at JSONY. https://github.com/ingydotnet/jsony-pm#readme
