Installation

npm install rd-utility-ahkIn your code include the following:

U := new rd_Utility()Description
rd_Utility is a utility class providing string, file and miscellaneous methods for Autohotkey.
All methods have function comments and if you're looking for examples check out the tests.
If you use the VS Code AutoHotkey Plus Plus extension, you might also want to check out Peak Definition (Alt+F12) or Go To Definition (F12).
These classes will throw an exception in case of a serious error by default which works well in combination with a global error handler. This behavior can be changed by setting rd_Utility.throwExceptions := false.

This comes with a speed penalty though, see a benchmark here.
