Usage

Getting values from an infofile:

getDouble

Returns a double value from an infofile for a given key or an array of keys. The value will be returned as a number.

Getting a single double value from an infofile:

// import the library
const infofile = require("@ipguk/infofile-utils");

// get the absolute path to the infofile
const file = "C:\infofiles\infofile";

// get the double value for the keys "WheelCarrier.fl.mass"
const wheelCarrierValue = infofile.getDouble({file, keys:"WheelCarrier.fl.mass"});

// console.log the value, returns a double e.g. "0.5"
console.log(wheelCarrierValue)

Getting an array of double values from an infofile:

// import the library
const infofile = require("@ipguk/infofile-utils");

// get the absolute path to the infofile
const file = "C:\infofiles\infofile";

// get the double values for the keys "WheelCarrier.fl.mass" and "WheelCarrier.fr.mass"
const wheelCarrierValues = infofile.getDouble({file, keys:["WheelCarrier.fl.mass", "WheelCarrier.fr.mass"]});

// console.log the values, returns an array of objects with the keys "keys" and "value" e.g. [{keys: "WheelCarrier.fl.mass", value: 0.5}, {keys: "WheelCarrier.fr.mass", value: 0.5}]
console.log(wheelCarrierValues)
