WSHModule

WSHModule is a JavaScript virtual machine built in WSH/JScript.

It is a subset of the JavaScript interpreter that supports to compatible with the ECMAScript 5 standard in WSH/JScript. WSHModule's script run at module scope (CommonJS/UMD) that means it can use require, exports and module objects. WSHModule can assist to upgrade JScript in Windows Script Host as much as possible to approach the ECMA-262 standard.

Possibly, better to use Node.js it would be quickly. However, JScript has been bundled with Windows. Improves a local environment when run a batch script with extension "js" by the passage to WSHModule.

Compatibility

• Windows (32bit/64bit)

WSHModule will work with WSH version 5.6 or later.

Currently, WSHModule does not use file type association and Windows environment (eg., PATH).

Features

WSHModule supports the following features:

• Supports ECMAScript5 standard syntax.
• Supports CommonJS Universal Module Definition (UMD).
• Working with UTF-8 encoding.
• Supports standard DOM functions: alert/confirm/prompt, setTimeout/clearTimeout and setInterval/clearInterval.
• Supports a console window.
• Fixed JScript bug: try-finally statements, String.prototype.substr, Array.indexOf and Array.prototype.splice functions to standard ECMA-262.

Quickstart usage

Runs script with WSHModule:

WSHModule.exe "C:/path/to/myscript.js"

or

Execute (drag-drop) C:/path/to/myscript.js to WSHModule.exe

Simple way:

1. Create a shortcut of WSHModule.exe to desktop.
2. Execute script by drag-drop to shortcut.

Tests

Runs test script:

1. cd WSHModule
2. "bin/WSHModule.exe" "scripts/test.js"

ToDo

• Getter and Setter support.
• "use strict" syntax support.

Dev

• bin/src/WSHModule is built on Lazarus (Free Pascal)

Build

1. Copy bin/wshmodule.wsf and bin\wshmshell.js to bin/src/WSHModule folder
2. Download Lazarus IDE and Install
3. Project -> Open Project -> Open bin/src/WSHModule/WSHModule.lpr (Change All files (*.*))
4. Confirm dialog The file "WSHModule.lpr" is not a Lazarus project. Create a new project for this "program"? -> Create project
5. Select Application
6. Run (Menu Run -> Run) or Build (Menu Run -> Build)

You can get a WSHModule.exe by build, and also run JavaScript with WSHModule console, for example, typing 1+1 and press enter key in the console window, you can get result 2.

JavaScript API

Global

• __filename : Current filename
• __dirname : Current dirname

Example

console.log(__filename); // C:\path\to\your_script.js
console.log(__dirname); // C:\path\to

Clipboard

Example

var clip = require('clip');
clip.set('test');

Available format: 'text' or 'html'

• get ([format = 'text']) : Get clipboard text as [format]
• set (data, [format = 'text']) : Set data to clipboard as [format]
• empty() : Empty clipboard data
• hasFormat(format) : Check whether clipboard has a format
• getAsText() : A shortcut of get('text')
• getAsHTML() : A shortcut of get('html')
• setAsText(data) : A shortcut of set(data, 'text')
• setAsHTML(data) : A shortcut of set(data, 'html')
• copy() : Emulate copy command of the keyboard
• paste() : Emulate paste command of the keyboard
• cut() : Emulate cut command of the keyboard
• getSelectedText() : Get selected text to clipboard (shortcut of copy() and get())
• print(text) : Print clipboard text (shortcut of set(text) and paste())

fs

Local file system utility

var fs = require('fs');
console.log(fs.readFileSync('./test.txt'));

• renameSync(oldPath, newPath) : Rename file oldPath to newPath
• statSync(path) : Get file stat
• unlinkSync(path, force = false) : Remove file
• existsSync(path) : Check whether a file exists
• readFileSync(filename, encoding = 'utf-8') : Read content from filename
• writeFileSync(filename, data, encoding = 'utf-8') : Write content data to filename
• copySync(src, dst, overwrite = false) : Copy file src to dst
• moveSync(src, dst) : Move file from src to dst
