Auto Switch Input Method

A VSCode extension that automatically switches input methods when switching between different editor groups.

Features

• Automatically switch to a default input method (e.g., English) when a text editor becomes active
• Restore the previous input method when leaving the text editor (e.g., switching to a non-editor panel in another group)
• Uses im-select for cross-platform input method switching

Note: This extension monitors onDidChangeActiveTextEditor events within VSCode. It does not detect when the VSCode window itself loses focus to another application.

Requirements

• im-select must be installed on your system

Configuration

Setting	Type	Default	Description
autoSwitchInputMethod.imSelectPath	string	/path/to/im-select	Path to im-select executable
autoSwitchInputMethod.defaultInputMethod	string	""	Default input method code when editor is focused
autoSwitchInputMethod.switchDelay	number	100	Debounce delay (ms) — also prevents false triggers when switching tabs
autoSwitchInputMethod.verbose	boolean	false	Enable debug logging in console

Usage

1. Install im-select for your platform
2. Run im-select in terminal to get your current input method code
3. Configure the extension settings:
   • Set autoSwitchInputMethod.imSelectPath to the full path of im-select executable
   • Set autoSwitchInputMethod.defaultInputMethod to your preferred input method code (e.g., English keyboard)

Example Configuration

{
  "autoSwitchInputMethod.imSelectPath": "C:\\im-select\\im-select.exe",
  "autoSwitchInputMethod.defaultInputMethod": "1033"
}
