AutoHotkey Plus Plus (AHK++)

AutoHotkey Plus Plus (AHK++) provides AutoHotkey language support for VS Code. This includes:

  • IntelliSense
  • code highlighting
  • basic debug support
  • code formatting
  • ...and more!

Currently, AHK++ officially supports only AHK v1. AHK v2 will likely work, but please open issues and be patient if complex workflows are not supported. See issue 146: Support AHK v2

AHK++ is a fork of AutoHotkey Plus by cweijan, with the primary goal of fixing bugs and adding user-requested features.

Why AutoHotkey Plus Plus?

AutoHotkey Plus Plus is one of many extensions that offer VS Code language support. So why should you use this one?

  • IntelliSense: Smart code completion, syntax highlighting, code navigation, and more.
  • Actively Maintained: Any issues encountered while using this extension can be reported and fixed. With other extensions, anything that's broken will stay broken forever. You can report any issues with AHK++ (and view all issues) through the issue tracker.
  • Debug Support: Run and debug AHK scripts from VS Code.
  • New Features: Another benefit to active maintenance is that AHK++ can add new features as users request them.

Install

Install from VS Code or install from VS Code Marketplace: Install AutoHotkey Plus Plus.

Commands

With AHK++, you can compile, debug, and run your scripts with keyboard shortcuts. You can also run a selection as a standalone script. Additionally, you can Open Help with Ctrl + F1.

  • Compile: Ctrl + Shift + F9
  • Debug: F9
  • Open Help: Ctrl + F1

Formatter Directives

Formatter directives instruct the formatter to behave a certain way on sections of code.

The only directive currently supported is FormatBlockComment and it's used as below:

/*
;All text inside block comment will be formatted like regular code.
*/
