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:

var util = require('ps-util-is');

• As a module for scripts that uses #include:

#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:

// 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:

// 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
