ps-util-is

This module copies functionality of core-util-is v1.0.2 for ExtendScript.

Installation

``npm i ps-util-is`

Usage

* As a module for scripts that uses this template:

`javascript
var util = require('ps-util-is');
`
* As a module for scripts that uses `#include`:

`javascript
#include "{path_to_bundle}/ps-util-is.jsx"
var util = require(ps-util-is);
`

typeof

The behavior of the typeof operator in ExtendScript differs from node.js:
`javascript
// ExtendScript
var re = /a*/gim;
$.writeln(typeof re); // function !!!
//Node
var re = /a*/gim;
console.log(typeof re); // object
`
This module takes core-util-is as "source of truth", so:
`javascript
// ExtendScript
var re = /a*/gim;
$.writeln(isObject(re)); // true
$.writeln(isRegExp(re)); // true
$.writeln(isFunction(re)); // false
`

isArray

This module will search for Array.isArray() polyfill. For example, ps-scripting-es5shim relies on __class\_\_ property, and code in this repo relies on Object.prototype.toString

Tests

Tests will be kept only in github repo.
If you want to test on another dataset do the following steps:

1) Get files from this repo, then `npm install`
2) ./test/data/test_data.js change data as you need.
3) [OPTIONAL] `nmp run watch` just in case (rebuild bundles).
4) run ./build/test_bundle.jsx in ESTK, or in target app. This will rewrite ./test/data/ps-util-is-result.js
5) `npm test`` see test results in console
