AutoHotKey进程等待脚本优化：需兼顾进程启动与用户输入中断

Got it, let's sort out this script for you. The core issue with your original code is that Process, Wait blocks the script entirely when there's no timeout set—so it can't listen for user input at all. Plus, the A_TimeIdlePhysical check was backwards from what you needed. Here's how to fix it properly:

First: Check for Existing Process on Startup #

First, we need to exit immediately if SomeProcess.exe is already running when the script starts. That's straightforward:

; Exit right away if the target process is already running
Process, Exist, SomeProcess.exe
if (ErrorLevel) {
    ExitApp
}

Option 1: Listen for Any User Input (Keyboard + Mouse) #

This solution captures any keyboard press or mouse click to terminate the wait, while checking for the process at regular intervals. It uses message listeners to catch user input events:

; Initial check as above
Process, Exist, SomeProcess.exe
if (ErrorLevel) {
    ExitApp
}

; Register listeners for common user input events
OnMessage(0x0100, "OnUserInput")  ; Catch keyboard key presses
OnMessage(0x0201, "OnUserInput")  ; Catch left mouse button down
OnMessage(0x0205, "OnUserInput")  ; Catch right mouse button down
OnMessage(0x0203, "OnUserInput")  ; Catch middle mouse button down

; Loop to check for process start with short timeouts
Loop {
    ; Wait 100ms for the process to start (non-blocking enough to catch input)
    Process, Wait, SomeProcess.exe, 0.1
    if (ErrorLevel) {
        ; Process started! Exit the script
        ExitApp
    }
    ; If user input is detected, OnUserInput will exit the script automatically
}

; Triggered when any user input is detected
OnUserInput() {
    ExitApp
}

How This Works: #

• The OnMessage hooks listen for low-level keyboard and mouse events. Any input triggers the OnUserInput function, which immediately exits the script.
• The Process, Wait, , 0.1 uses a 100ms timeout, so the script never blocks for long. Every 100ms, it checks if the process started—if not, it loops back and keeps listening for input.

Option 2: Keyboard-Only Input (Simpler) #

If you only care about keyboard input (not mouse clicks), you can use the Input command instead of message listeners. This is more concise:

; Initial check
Process, Exist, SomeProcess.exe
if (ErrorLevel) {
    ExitApp
}

Loop {
    ; Check if the process has started
    Process, Exist, SomeProcess.exe
    if (ErrorLevel) {
        ExitApp
    }
    ; Wait 100ms for keyboard input; if none, loop again
    Input, , T0.1 V
    ; If input was detected (not just a timeout), exit
    if (ErrorLevel != "Timeout") {
        ExitApp
    }
}

Why Your Original Code Failed #

Your original line while (A_TimeIdlePhysical > 100) { Process, Wait, SomeProcess.exe } had two big issues:

1. Process, Wait with no timeout blocks the script indefinitely—so it can't respond to any user input until the process starts.
2. A_TimeIdlePhysical > 100 checks if the system has been idle for over 100ms, which is the opposite of what you wanted (you want to stop waiting when the user does input something).
