AutoHotKey IfWinExists Not Working With ReGex-CodePudding

I have a window title something like this: ComInstr - Q4NATIONAL-11.21(1).pdf - Google Chrome

I want to use IfWinExist to let me know if that windows exists. I do this:

SetTitleMatchMode Regex

IfWinExist i)\..{3,4} - Google Chrome
{   
  Msgbox Here
}
return

The title of the window will change, but it will always contain a dot and 3 or 4 characters (an extenstion) and then - Google Chrome.

This doesn't work and I don't know why. Any advice?

Okay, not sure why but this works:

SetTitleMatchMode Regex 
regex_match:="\..{3,4} - Google Chrome"
IfWinExist %regex_match%
{

CodePudding user response：

You would need to escape the comma with `,.
Otherwise your arguments to the IfWinExist^(docs) command are as follows:

WinTitle = i)\..{3
WinText = 4} - Google Chrome

So, be sure to escape the comma:
IfWinExist i)\..{3`,4} - Google Chrome

But really, you shouldn't use legacy AHK.
IfWinExist is a deprecated legacy command and should no longer be used.
Use WinExist()^(docs) along with the modern if ()^(docs) instead.

In modern AHK you don't need to worry about the troubles legacy syntax will bring you here since you're explicitly specifying strings inside "":
if (WinExist("i)\..{3,4} - Google Chrome"))
