Autohotkey: how to determine if a text file is opened in emac or notepad3 - autohotkey

Question

I need to determine the path and file name of an open text file, whether it is opened in Notepad3 or in Emacs.
For both editors the path and file name are displayed in the window title of the opened file. Hence, I can use the AHK function WinGetTitle to extract the window title, and then the function SubStr to extract the path and file name from the window title.
However, the two editors differ in how the path and filename are displayed in the window title. In Notepad3 the title format is [filename][path], while in Emacs (my configuration) the format is [path][filename].
I would like my code to be usable regardless which of the two editors the text file is opened in. I guess I have to use some sort of an if-statement.
My pseudo code looks like this:
::uuu::
; find the window title of the opened txt file
WinGetTitle, windowTitle, A
; determine if text file is opened in Notepad3 or in Emacs
appName = <some function>
; construct file name and file path from window title
if appName = notepad3
fileName := SubStr(windowTitle,3,24)
filePath := SubStr(windowTitle,29,-12)
elseif appName = emacs
fileName := SubStr(windowTitle,-23)
filePath := SubStr(windowTitle,1,-24)
end
; send input to file
SendInput, %windowTitle% {enter}
SendInput, %fileName% {enter}
SendInput, %filePath% {enter}
return
1) what AHK function can be used to determine appName?
2) if appName can be determined, how should the if-statement in my code be made in correct AHK syntax?

Answer 1

I think I figured out one way to solve my own question:
::uuu::
; find the window title of the opened txt file
WinGetTitle, windowTitle, A
; find the process or app used to open the text file
WinGet, process, ProcessName, A
; construct file name and file path from window title
if (process = "Notepad3.exe")
{
fileName := SubStr(windowTitle,3,24)
filePath := SubStr(windowTitle,29,-12)
}
else if (process = "emacs.exe")
{
fileName := SubStr(windowTitle,-23)
filePath := SubStr(windowTitle,1,-24)
}
; send input to file
SendInput, %windowTitle% {enter}
SendInput, %fileName% {enter}
SendInput, %filePath% {enter}
SendInput, %process% {enter}
return
