Simple Data Notation (SDN)

Simple Data Notation started as a project to create a library that used regularexpressions that could be used in small projects. The initial setup for SDN was a simple setup without nesting. This is a more robust version with nesting. SDN was not created with amazing performance in mind, It is a test project to experiement with regex with a gaol in mind. SDN builds a dll that you can link into your .net projects SDN is made for .netcore 2.2

SDN format

# strings: captures everything between ""
data: [
    "This is a piece of text",
    "this is a piece of text"
]

# nesting of objects
scene: [
    name: [menu]
    objects: [
        player: [
            name: [player1]
            lvl: [1]
            str: [10]
            int: [7]
            dex: [9]
            hp: [14]
            attack: [4]
            inventory: [10, 20, 33, 120] # simple array support
        ]
        frog_enemy: [
            name: [frog]
            lvl: [2]
            hp: [4]
            attack: [4]
        ]
    ]
]

Features

• nesting
• capture everything between qoutes
• get tokens with a path (scene.objects.player)
• typing
• fix parse performance

Takeaways

• do's and dont's with regular expressions
• making shared libraries with .netcore
• How to optimize a regular expression
