math.js range override bug

mathjs_range_bug.js

const math = require('mathjs')

// define factory functions for range and reshape
function myRangeFactory (type, config, load, typed) {
  return (() => 12)
}

function myReshapeFactory (type, config, load, typed) {
  return (() => 21)
}

const factoryArr = [
  {
    name: 'range',
    factory: myRangeFactory
  },
  {
    name: 'reshape',
    factory: myReshapeFactory
  },
]

// uncomment to override using non factory function
// this will work, and subsequently overriding `range` using factory function will work
//math.import({ range: () => 13 }, { override: true })

// attempt to override using factory function
// this works for reshape but NOT for range
math.import(factoryArr, { override: true })

const rangeEval = math.eval('range(2,5)')
const reshapeEval = math.eval('reshape(2,5)')

// this _should_ be 12
// if it is [2,3,4,5] then the original function was not overwritten
console.log('range(2,5) evaluates to', rangeEval)

// note that reshape can be overritten with a single factory function without issue
// should return 21
console.log('reshape(2,5) evaluates to', reshapeEval)
