JON

JON (Jacy Object Notation) is an alternative for JSON used by Jacy programming language.

Note: JON grammars for different IDEs are inside Jacy packages for IDEs.

Example:

// JON Supports C-style comments
/*
 * Block comments too
 */

string: 'String is enclosed into quotes'
string2: "Either single or double"

multiline: """
Multiline strings are enclosed into triple double quotes
"""

multiline2: '''
or in triple single quotes
'''

'Key can be a string': 'Value'

object: {
    description: 'Objects are enclosed into {}'
    also: 'Root of the whole file is an object by default'
}

array: [
    'Arrays are enclosed into []'
]

items: {
    separator: 'Items in objects and arrays are separated either with , or new-line'
    also: 'Comma is optional if new-line is present'
}

numbers: {
    integer: 34958
    integerHex: 0x123213
    integerBin: 0b101010
    integerOcto: 0o234221

    float: 0.12312321
    floatWithExponent: 0.123e-10
}

// Boolean values
yep: true
nope: false

// null is no-value constant
nothing: null

Specification

JON does not specify mostly anything except grammar, client (implementation) needs to handle everything else, including numbers size limit, etc.

Constants

Implementation is considered valid if true, false and null corresponds to right meanings which are:

• true/false - boolean values
• null - no-value (read further)

null value

null must not differ in implementations in the way of processing it, if null appears as value -- it must exist in the representation of source code. null is not "undefined", it is a "none" value, thus appearance of null does not mean that value can be omitted.

Numbers

JON does not require any limitation for numbers, grammatically valid number can be of any length. Each implementation need to handle size by itself and should do it.
