So, I make this, a AutoHotKey debug adapter written by AutoHotKey. Not bad, isn't it?

Get it from here:
Download
or install from vscode extension marketplace directly by search: autohotkey and debug
It is still a very early release. Some bugs need to be solved. But, it is able to debug a ahk source file.
