Omni’s customJS technical documentation

Welcome to the technical documentation of Omni’s customJS. This is the only technical part of the guide; I promise. It might be a bit more boring than normal, but it has been designed to be pretty much a translation of the old polish documentation found on Daniel’s gist. If you’re looking for a user guide, code examples and tips and tricks for making your own customJS, we recommend you go to Standard use of customJS or to From Calculatorian to Calculatorian

• Create a Value Select
• Create a Value Setter
• Define custom calculator functions
• On Initialization (context)
• On Result (context)

Introduction

To simplify the process of creating and editing a calculator in customJS, Omni provides a set of personalized instructions that act as a translation between the pure javascript and the calculatorian.

In this section we will take a look at all of them from a technical point of view. For each element we will see its behaviour, its syntax and the input and output parameters required.

If you are looking for a practical explanation and practical usage guide, head to the section STD usage of customJS were we will take a look at how to achieve the desired behaviour in our calculator by using and combining the different elements available.

Warning

Whenever you edit customJS for your calculator you should add 'use strict'; at the very top of the code. Don’t ask why, don’t question it, just follow instructions. This bit of code has been omitted from most snippets of code in this documentation, but you must remember to put it.
