Execute JavaScript Scripts

TextGO supports using JavaScript to write custom scripts for text processing. JavaScript scripts can perform various complex text transformation and processing operations, greatly extending TextGO's capabilities.

Feature Overview

JavaScript scripts allow you to:

• Use JavaScript to process text
• Leverage the rich JavaScript standard library and ecosystem

Runtime Environment

TextGO uses Node.js or Deno to run JavaScript scripts.

Supported Runtimes:

• Node.js: The most widely used JavaScript runtime
• Deno: Modern, secure JavaScript/TypeScript runtime

Auto-Detection:

• TextGO automatically detects available runtimes on your system
• Node.js is prioritized; if unavailable, Deno is used
• Custom runtime paths can be specified in settings

Create JavaScript Script

Step 1: Access Script Management

1. Open "Settings" > "Script Execution"
2. Click the "+" button to add a new script

Step 2: Basic Information

Script Name (Required)

• Used to identify this script
• Recommend using a descriptive name

Script Icon (Optional)

• Click the icon selector to choose an icon
• Supports built-in icon library
• Supports uploading custom SVG icons

Script Type

Step 3: Write the Script

JavaScript scripts must contain a process function:

function process(data) {
  // data.clipboard - Clipboard content
  // data.selection - Selected text

  // Return processed text
  return '';
}

Parameter Description:

• data: Object containing input data
  • data.clipboard: Current clipboard text content
  • data.selection: Selected text content

Return Value:

• Must return a string
• Returned content serves as the processing result
• Can return an empty string

Use JavaScript Script

After creating the script, you can use it in shortcut rules:

1. Open "Global Shortcuts"
2. Add a new rule
3. Select your created JavaScript script in "Execute Action"
4. Save the rule

JavaScript Script Examples

Example 1: Text Reversal

function process(data) {
  return data.selection.split('').reverse().join('');
}

Example 2: Character Count

function process(data) {
  const text = data.selection.trim();
  return text.length;
}

Example 3: Remove Duplicate Lines

function process(data) {
  const lines = data.selection.split('\n');
  const unique = [...new Set(lines)];
  return unique.join('\n');
}
