Hjson is an attempt to make JSON more human readable.

Hjson is a syntax extension to JSON. It's NOT a proposal to replace JSON or to incorporate it into the JSON spec itself. It's intended to be used like a user interface for humans, to read and edit before passing the JSON data to the machine.

Let's take a look at examples to see the key syntax differences!

    # Comments are totally supported!
    
    // With forward slashes too!
    
    /*
        Even block style comments, neat!
    /*
    
    # Strings do not require quotes!
    # Just keep it to a single line
    human: readable
    quotes: "are fine too"
    
    # Notice that commas are also not required!
    # If using commas, strings DO require quotes!

    }

        I wish JSON was more human readable.
        If only there was a JSON for my needs!
        Oh wait.. there is! It's called Hjson.
        '''
    
    # Backslashes are interpretted as an escape character ONLY in quoted strings
    slash: This will not have a new line\n
    slash-quoted: "This will definitely have a new line\n"

    # Make sure to use quotes when mixing whitespace with important punctuation
    example1: "If, you're, going, to, comma in a string, use, quotes!"
    example2: "Also if you want to use {} or [] or any JSON relevant punctuation!"
    example3: [because, this, is, totally, BROKEN!]
    example4: this is technically OK though: {}[],:
