I did not quite understand you requirement, how about placing an alert inside the method defintion saying it was called, like the following

function doUnStyler
{
 alert("You called doUnStyler")
//do your stuff here
}

Thank you for your reply but i mean when function is finshing executing and all the function code is done!, how to alert the user that the function is done befor exit the script?

[Manan Joshi]

The answer remains the same as above, just the alert line becomes the last line of the function definition, unless it has some other routes of exit.

If you could show a simple example of your code decribing what is needed while the code flows across functions maybe i will be able to give a better idea

I tried it here but still alert the user before it real finishing the code, here is the code :

//Remove all Object Styles, Paragraph Styles, Character Styles
//Developed By Neal Derek
//Additional Developing : Mohammad Ibrahim

//Activate Undo Feature for this Script
if (parseFloat(app.version) < 6)
doUnStyler();
else
app.doScript(doUnStyler, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, "UnStyle all Object,Paragraph,Character Styles");
//Start the Function
function doUnStyler() {
//Remove all Object Styles, Paragraph Styles, Character Styles
#target InDesign    
    myDoc = app.activeDocument;         
    var chs1 = myDoc.characterStyles.length;    
    for(var j=chs1-1; j>0; j--) //j++ replaced here by j--    
    {    
      var CharRes = myDoc.characterStyles[j].remove();    
    }    
  var pghs1 = myDoc.paragraphStyles.length;    
    for(var j=pghs1-1; j>1; j--)//j++ replaced here by j--    
    {    
      var PSRes = myDoc.paragraphStyles[j].remove();    
    }    
  var objs1 = myDoc.objectStyles.length;    
    for(var j=objs1-1; j>0; j--) //j++ replaced here by j--    
    {    
      var ObjRes = myDoc.objectStyles[j].remove();    
    }
//Check if the Program is Done
 alert("Finished")
}

How did you come to the conclusion that the alert is shown before the code execution is finished. I see the script deletes the styles properly before the alert pops up. What am i missing here? Which version of InDesign are you using?

Im using InDesign 2020 (15.1.1) I have test it on 50 page document , and alert start very early!, if you test it in One Page only you will feel its normal

Hello Mohammad

you could try waitForTask();

//Remove all Object Styles, Paragraph Styles, Character Styles
//Developed By Neal Derek
//Additional Developing : Mohammad Ibrahim

//Activate Undo Feature for this Script
if (parseFloat(app.version) < 6)
doUnStyler();
else
task = app.doScript(doUnStyler, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, "UnStyle all Object,Paragraph,Character Styles");
//Start the Function
function doUnStyler() {
//Remove all Object Styles, Paragraph Styles, Character Styles
#target InDesign    
    myDoc = app.activeDocument;         
    var chs1 = myDoc.characterStyles.length;    
    for(var j=chs1-1; j>0; j--) //j++ replaced here by j--    
    {    
      var CharRes = myDoc.characterStyles[j].remove();    
    }    
  var pghs1 = myDoc.paragraphStyles.length;    
    for(var j=pghs1-1; j>1; j--)//j++ replaced here by j--    
    {    
      var PSRes = myDoc.paragraphStyles[j].remove();    
    }    
  var objs1 = myDoc.objectStyles.length;    
    for(var j=objs1-1; j>0; j--) //j++ replaced here by j--    
    {    
      var ObjRes = myDoc.objectStyles[j].remove();    
    }
//Check if the Program is Done
 task.waitForTask();
 alert("Finished")
}

you may need to move the "task = " to  function doUnStyler()

Regards,

Mike

Edit:   Please disregard my mistake, waitForTask(); is for background task.

JS is by nature async so it could be possible that in a big document this happens. There is not much we can do here in my opinion, we can't force the sync behaviour. One idea is try putting the alert after doScript and then check.

Thank you very much

ExtendScript predates anything async in JavaScript by a decade.

A problem of the alert in the middle of the script execution may be that InDesign's text processing "composer" is async and not completed when the alert dialog shows and blocks all other InDesign processing (kind of the opposite of async). You may eventually get around that by adding this line before the alert(), it forces the composer to complete.

app.activeDocument.recompose()

That's a fine idea Dirk. I meant the same where the api's return promptly and might lead to cases where the effect is not yet registered totally as you explained. i think your suggestion should work. Thanks for sharing your thoughts
