SMILE - simple markup language

SMILE is similar to YAML, but much more simple to learn and use.

Install

npm

npm i smilelang

html

<script src="https://unpkg.com/smilelang@1.1.3/bundle.js"></script>

<script>
var SMILE = require('smilelang')
</script>

SMILE data types

string

'some string'

A string is any collection of characters. It must have a single quote at the beginning to open the string and a single quote at the end to close it.

number

examples

123
245.7
0.5

boolean

true
false

A boolean is a special type which must be one of two possible values, either true or false.

no set value

null

The value null is used to specify that there is no set value.
Unlike languages such as JSON (no value of enumerable type - [], no value of object type - {}), Smile does not have different types of no set value. In Smile all of these are just no set value: null

object

name: 'Steve'
age: 30
homeless: false
children: null
address:
  country: 'USA'
  city: 'New York' 

An object is a set of keys and values. the pattern is key: value.
key is any characters, including whitespaces, except :. For example name or age
value is any value of the types above (string, number, boolean, null) or object or list types (list is discussed below).

nested object

address:
  country: 'USA'
  city: 'New York' 

to show that the address key has value of an object, leave address: on the first line and write next object key:value pair in the next line. Put 2 whitespaces before the key so that compiler will know that the next object belongs to the address key. Depth is not limited, you can create nested objects inside nested objects.

address:
  country: 'USA'
  contact:
    email: true
    phone: false
  city: 'New York' 

list

- 'Smith'
- 'Doe'
- 'Jones'
- 123
- true
- null
-
  name: 'Tony'
  surname: 'Stark'

list is similar to an object, but instead of key: you have - sign. It is usefull in cases where you don’t need key for each item and want to get the item by it’s index, for example item number 2.
List can have the same values as object (string, number, boolean, null, object, list)

make list a value to object key

members:
  - 'Tony Stark'
  - 'Spiderman'
  - 
    squadName: 'best'
    members:
      - 'me'
      - 'you'

That is all

I hope you find it very simple and easy to use.

Especially when compared with YAML!

  surname: "Stark"
}

SMILE.stringify(demoObject)
/*
OUTPUT:

name: 'Tony'
surname: 'Stark'

*/

// parse
var str =`
