AutoHotKey Help, matching character and replacing - autohotkey

Question

My save feature, note I do not want to know better ways to save it or corrections to my save code, I just need help on the part where I need it to automatically remove additional non required/old brackets generated on save:
Here's the save button:
buttonSave:
FileAppend,
(
nprocess,exist, %Input%
nprocess,priority, %Input%, %PriorInput%
}
), C:\Users\%A_UserName%\Desktop\AutoSetup\Settings.ahk
MsgBox, 0, Saved, %PriorInput% Priority to %Input% has been saved.
How can I get AutoHotkey to find } and remove any matching the char } and then add one } at the very end of the file, and have this looped?
I have a save feature and the output is this:
loop
{
process,exist, Steam.exe
process,priority, Steam.exe,
}
process,exist, Steam.exe
process,priority, Steam.exe,
}
I want it to find the end } and the middle } remove both of them and then add a single } at the very end. If you save, it always adds a bracket at the bottom.

Answer 1

buttonSave:
FileRead, Contents, C:\Users\%A_UserName%\Desktop\AutoSetup\Settings.ahk
if not ErrorLevel ; Successfully loaded
{
StringTrimRight, Contents, Contents, 1 ; remove the end }
FileAppend, %Contents%, C:\Users\%A_UserName%\Desktop\AutoSetup\Temp.ahk
Contents = ; Free the memory
}
FileAppend,
(
process,exist, %Input%
process,priority, %Input%, %PriorInput%
}
), C:\Users\%A_UserName%\Desktop\AutoSetup\Temp.ahk
FileMove, C:\Users\%A_UserName%\Desktop\AutoSetup\Temp.ahk, C:\Users\%A_UserName%\Desktop\AutoSetup\Settings.ahk, 1 ; overwrite existing file
; Run, edit C:\Users\%A_UserName%\Desktop\AutoSetup\Settings.ahk
MsgBox, 0, Saved, %PriorInput% Priority to %Input% has been saved.
; reload ; if Settings.ahk is included in this script
return

Answer 2

I'd use something like this (The loop causes high CPU utilization):
#NoEnv
#SingleInstance Force
#Persistent
Menu, Tray, Add
Menu, Tray, Add, Add Process, Add_Process
Menu, Tray, Default, Add Process ; doubleclick the tray icon to add a new process
SetTimer, set_priority, 500
return
set_priority:
Process,exist, Notepad.exe
Process,priority, Notepad.exe, L
; Add Process
return
Add_Process:
InputBox, ProcessName, ProcessName, Enter a Process.
if !ErrorLevel
InputBox, priority, priority, Enter a priority.
if !ErrorLevel
{
text =
(
Process,exist, %ProcessName%.exe
Process,priority, %ProcessName%.exe, %priority%
; Add Process
)
FileRead, Contents, %A_ScriptFullPath%
if not ErrorLevel ; Successfully loaded
{
StringReplace, Contents, Contents, `; Add Process, %text%
FileAppend, %Contents%, %A_ScriptDir%\Temp.ahk
Contents = ; Free the memory
}
FileMove, %A_ScriptDir%\Temp.ahk, %A_ScriptFullPath%, 1 ; overwrite existing file
reload
}
return
