StateMachineParser

Check what an IOI state machine would return given an input.

What's an IOI state machine?

An IOI state machine is what we call a part of the JSON scripting system used within the Glacier engine.

For example:

{
    "$eq": ["$Value.MyParameter", "Hello"]
}

That is a state machine condition that checks if $Value.MyParameter is "Hello".

Normally, only the actual Glacier engine could check the output of this condition, but this parser can also do it.

yarn add @peacockproject/statemachine-parser

Usage

const { test } = require("@peacockproject/statemachine-parser")

const condition = {
    $eq: ["$Value.Greeting", "Hi!"],
}

const result = test(
    condition, // the state machine condition
    {
        Value: {
            Greeting: "Hi!",
        },
    }, // the variables object, which is essentially the input values.
)
