Using ASObjC Runner to Cancel a Shell Script Command in Applescript

I have an ASObjC Runner code on my AppleScript that shows a progress window after launch do shell script. How to make the button in the execution window kill the shell script?

Here is a sample of my code:

tell application "ASObjC Runner"
    reset progress
    set properties of progress window to {button title:"Abort", button visible:true, indeterminate:true}
    activate
    show progress
end tell

set shellOut to do shell script "blahblahblah"
display dialog shellOut

tell application "ASObjC Runner" to hide progress
tell application "ASObjC Runner" to quit

There are several parts to the answer:

  • Asynchronous do shell script: usually do shell scriptreturned only after the shell command completes, which means that you cannot manipulate processes inside the shell. However, you can get a command do shell scriptto asynchronously execute the backgrounding of the shell command that it executes, i.e.

    do shell script "some_command &> /target/output &"

    - . , , , ( /dev/null, ). echo $! , do shell script PID . , do

    set thePID to do shell script "some_command &> /target/output & echo $!"

    . TN2065. - do shell script "kill " & thePID.

  • ASObjC Runners - button was pressed true:

    repeat until (button was pressed of progress window)
    delay 0.5
end repeat
if (button was pressed of progress window) then do shell script "kill " & thePID

  • , script , :, , . ps PID, , , , ..

    if (do shell script "ps -o comm= -p " & thePID & "; exit 0") is ""

    true, .

:

tell application "ASObjC Runner"
    reset progress
    set properties of progress window to {button title:"Abort", button visible:true, indeterminate:true}
    activate
    show progress

    try -- so we can cancel the dialog display on error
        set thePID to do shell script "blahblahblah &> /file/descriptor & echo $!"
        repeat until (button was pressed of progress window)
            tell me to if (do shell script "ps -o comm= -p " & thePID & "; exit 0") is "" then exit repeat
            delay 0.5 -- higher values will make dismissing the dialog less responsive
        end repeat
        if (button was pressed of progress window) then tell me to do shell script "kill " & thePID
    end try

    hide progress
    quit
end tell
